The invention relates to a method of applying the useful data are not amenable to direct the processing of data formats according to the generic concept of paragraph 1 of the claims, to a geodetic device according to item 14 or 16, geodetic system of paragraph 20, as well as the computer software product according to paragraph 10, the computer data signal according to paragraph 11 and the base directory or the data directory under paragraphs 12 or 13 of the claims.
In many geodetic applications and systems, there is a need for frequent or constant data transfer between different devices. This is preferably transmitted data with temporal or spatial support, which may contain parameters, measured values or regular messages, such as error messages. Examples of such data are the current time, the location measuring device together with the existing reference points, as well as the direction, distance and angle relative to the measurement points. This transfer can be performed by various suitable wired or wireless communications, for example, using a direct cable connection, as well as directional or non-directional radio data.
Without limiting the General applicability of the relevant invention pic is BA and relevant to the invention of devices as an explanatory example in this case can serve as their application for Differential Global Navigation Satellite System (D-GNSS), for example, a Global Positioning System (GPS). This includes purely illustrative presents data types and data formats that are in a similar embodiment can be used in many other applications.
In differential GNSS positioning of the mobile device, the so-called Rover (research mobile device)is performed by receiving data and measurement data on satellites and receiving data obtained by the measurement data relative to at least one base station. Since the location of the reference station is known, and it also receives identical signals from satellites, due to this differential correction method can be fixed some inaccuracies and errors. Through this method it is possible to achieve higher accuracy than the method with a mobile device without using a reference station. This station continuously transmits the mobile device data from the received satellite signals. Depending on the implementation it may be the original (raw) data or already prepared data.
In practice, the base station, however, more often than not are set anew for each measurement process, and uses a network of permanently installed reference station is th, which can also be used simultaneously by different users. These stations broadcast, along with related to satellites, data and time, specific information about themselves, such as a number of reference stations. In addition, you want to convey technical information, for example, the parameters of antennas or the correction parameters. Examples of such correction parameters can serve as atmospheric and geometric correction, which, for example, was determined in the network of permanent reference stations and related network software and can now be used to correct measurements of the mobile device depending on the distance to the reference stations.
As the use of data from the reference station must be possible for different mobile devices, the radiation signal is omnidirectional. In General, when there is a requirement that must also be possible Association with various systems in the field of radiation of the reference station, so need some form of standardization of formats of transmitted data.
One use for such data transmission standard for independent manufacturer's data formats installed Radio technical Commission for Maritime services (RTCM) (Alexandria, stevegynie, USA) the Concept of "data format" describes a complete block of information to be transferred between the geodetic instrument. Information exchange occurs through identical or different data formats on the same or different frequencies of data transmission. The concept of the "field data" describes the complete content of the data with the specified range of values. Data formats are, for example, from the code identification (ID) of the beginning, the various data fields and code recognition is completed, if necessary, with the checksum to validate the data when receiving. The term "data type" describes the possible expression, such as the length, unsigned or signed information block. The data types used in the description of the data fields.
Current standard RTCM V2.x consists of one or more header fields of the data as the main information that can be added as optional extras. The appearance of such additions to the data format specified by the so-called flags as indicators. This means that each sent message after its input side contains a sequence that indicates to the receiver whether to follow further additions, and if so, what. From this information, the receiver learns how he should interpret and process the data stream.
In General this solution, known from the prior art, is insufficient is to, namely, that the number of permutations possible when the applicable number of flags though relatively little, however, in spite of this not every manufacturer takes into account all possible permutations and processing related data in their devices. Known from the prior art solution for a limited number of flags is to define data formats, for example, from the selected permutations, and to provide a continuous code. This passed in the beginning of the message number of the device can output data format as a sequence of different data fields of the data types and, therefore, to evaluate the data field.
Although thus address space and, therefore, the number of options used messages can be considerably extended compared to the variant with the use of flags, there is a problem, which is that all transferable options should be provided in the software and hardware of the device. If the device accepts the message or data format with an unknown code, then immediate treatment is no longer made, although in this case, in the sequence of data fields are also critically evaluated data device data fields with useful and workable data.
Such a solution requires, modified and existing messages by adding new data formats or changes to existing data formats, required the development of a new version of software and hardware all manufacturers. In addition, this new variant after its development must be reproduced on all devices, which leads to high costs of coordination.
This is illustrated with differential GNSS system problems can occur when information exchange between other geodetic instruments. For example, a theodolite can communicate with other theodolites and/or intellectual reflective systems, we have a similar problem, since in this case there must be communication and interaction between devices from different manufacturers and different levels of development.
The present invention is to provide a method and associated devices, as well as information and technical elements, which provide a continuous change of the block of data.
In particular, should be ensured to prevent permanent coordination of existing geodetic instruments software and hardware-based processing or new development of the standard.
An additional objective is to provide automatic implementation of suitability for treatment is not amenable to direct the processing of forms is tov data.
Another objective is to provide machinability well as previous data formats.
Another objective is to provide the possibility of expanding the applicable data fields or data formats by introducing new data types.
These tasks in accordance with the invention are solved by the distinguishing signs of paragraphs 1, 14 and 16, and due to the distinctive features of the dependent claims these decisions will be improved later.
The proposed invention relates to a method, surveying instruments, surveying system, and computer program product, the computer data signal and a reference directory or data directory.
Transferable in accordance with the invention, messages are transmitted in a data format that consists of a sequence of at least two data fields. While one data field has, in principle, any length, so that the data fields within the data format can have different lengths. The information in each data field contained in a certain data type. Within the data format of the data fields can be repeated, for example, if the same data from multiple satellites are transmitted one after another, or the same information may be contained in multiple fields of different data types the data for example, when the transmission time in various forms of representation. This data field can be selected with a fixed length, in particular with length determined by geodetic data format location or time. The message may contain multiple indicators, such as flags or bits of parity. These items are also included accordingly in the concept of a data field.
The data format of each message is uniquely determined based on the encoding, which is preferably a numeric or alpha-numeric method. Each corresponding to the invention of the geodesic device that is configured to receive messages, there is a means for processing the payload, which can evaluate the set of known for this device data fields. In addition, the device has information about a number of data formats, that is, as contained data fields and their sequence in the device, known and may on the basis of encoding messages to be used as the basis for processing. These data formats are thereby set directly processed data formats that have exclusively allow evaluation of the data fields. While the concept of "permissive assessment" ("having the opportunity assessment", "p is daysies assessment") indicates, that by means of the device or is it the firmware can be implemented recognition and evaluation of the data contained in this data field. It does not require that the appropriate data is then actually processed for a particular purpose. The concept of "permissive assessment indicates, therefore, for potential use in the corresponding data field.
The term "geodetic instrument" in this relationship must be understood in a generic manner the devices, which serve for measuring or checking data with spatial support or configured to do this. In particular, it relates to the measurement location, the distance and/or direction or angles relative to one or more reference or measurement points. This applies not only to terrestrial systems, but also to such components which are used for positioning based on satellite measurements (e.g., GPS or GLONASS). In particular, under such geodetic instrument here should be understood, for example, stationary, mobile base stations or mobile stations, the so-called Rovers, as well as mobile devices of smaller dimensions, such as theodolites, as well as so-called full station as total stations with electronic the m angular measurement and electro-optical measurement of distance. Similarly the invention is suitable for use in specialized devices with similar functionality, for example in the artillery aiming circles in military equipment or industrial appliances control structures or processes; therefore, these systems are also included in the scope of the "geodetic instrument.
If there is a Supplement existing data formats by adding new data formats, these new data formats can not directly be processed, because the device contains no information about their structure. Approval and addition of data fields may, for example, be necessary to increase the resolution or for the implementation of the modified field values. As well as should be considered the optimal bandwidth and optimal communication, it is preferable to replace existing data formats on the newly defined data formats. However, new data formats can consist of permutations of the data fields known data format, or a new sequence of data fields. In case of an emergency such data formats also contain new types of data fields, which can neither be recognized by the device, nor be used. Thus, these data fields can not be evaluated.
Thus new, not giving directly the authorized processing data formats consist of a sequence of measurable and/or not measurable data fields.
In order nevertheless to be able to use beyond the immediate processing of data formats, the device must be able to identify or locate measurable data fields. Therefore, in accordance with the invention with two-way communication is transmitted reference directory, preferably in conjunction with the establishment of the communication connection between communication devices, while at one-way connection parts reference catalog can be transmitted in a distributed manner over a certain interval of time and with repetition through the determined data formats. Other cases automated or manually initiated transfer control catalog can also be an external process, such as notifying the host device that the message cannot be processed. For example, the receiving device may report that shall be adopted or passed beyond the immediate data processing, data format, or to give a message that this device is indicated data formats directly processed by this device. This message may then be taken transmitting the message by the device and to serve as an initiator for transmitting the reference catalog. In the same way, can also is performing some internal process in the transmitting device to function as such an initiator, for example, the elapsed time counter or process account or achievement and recognition timestamp, whereby, in particular, for example, through periodic timestamps may be due to the periodic transmission catalog. This recognition timestamp as mentioned initiator transfer can be carried out, in particular, during the lifetime of the connection relationship between devices.
Reference directory contains for each data format, the sequence of types of data formats. Thus, even when completely new, not amenable to direct the processing of the data format used one or more of the evaluated data formats. This provides the possibility of indirect processing of new data formats.
Alternatively, instead of directly specifying the sequence of data fields can be applied to another account. For example, new, not directly processable data formats can also be derived from known data formats due to the fact that the specified changes. In particular, in the case of new data formats, which can be represented only as a sequential ordering more short known data formats, offers this account, because this reference directory which may be formed shorter. In addition, the indication changes may be preferable in the case where there is already considerable stock of relatively short data formats, which can describe "quasimodular" more complex data formats. In this respect, such a short data formats are meta-data fields for the longer formats of the data at a higher level.
If the device or in it hardware and software is designed in such a way that these new types of data fields or new data types can be applied on the basis of at least one transmitted data directory, it is possible to make full use of new formats of data with the new data fields. The data directory can be executed and can be used like a reference to the directory and can, therefore, define new data fields or data types. If necessary, can also be the definition of data fields and data types in parallel in a shared directory. New data fields can be entered as extended descriptions of the previous data field. Thus, for example, to implement the expansion area or adaptation information resolution.
From the passed reference catalog follows the sequence of data fields that can now be known and evaluated illinoie and not measurable. While the measured field data on the basis of this information sequences can be localized and thus valued for not measurable data fields may not be obtained from the data directory, so that not any is still evaluating data fields can be used. In principle, it is possible to combine both types of directories in one directory, or to introduce additional levels of description and definitions of data and, if necessary, add more directories to be transferred. Reference directory or the data directory may, in accordance with the invention, be transmitted as a file in the same process or with the distribution of the blocks within a certain time interval, or as multiple processes. Use is then based on discrete blocks transferred or only after receiving the entire directory. In particular, when one-way communication can be periodic transmission of short parts reference catalog and/or catalog data, and this process is carried out after the complete transfer of the catalogue can also be repeated constantly, necessary in the case of interrupts. The transmission of the directory receives, and thus, the quasi-continuous nature. In this way, the receiving device becomes possible, later defined the time interval, get all of the relevant directory of sent messages and to recover from them the full catalog.
The above technical result is in accordance with the invention also provides computer-readable media, including the embodiment of such computer-readable media by electromagnetic wave having stored thereon program code that, when executed, his means of processing useful data, provides the steps of receiving data and processing the data payload in the claimed method of use of the useful data is not amenable to direct the processing of data formats.
The above technical result is in accordance with the invention is also provided supporting data directory stored as updating elements of software code on a computer readable medium that, when executing program code means for processing the payload, the implementation of the method according to any of paragraphs 1-9.

1 schematically shows the structure of geodetic data format according to the prior art involving the use of flags. An example of this form of implementation can serve as a standard RTCM V2.3. After identical for all data formats of the initial part And followed by bit 1 of the first flag, bit 2 of the second flag and bit 3 of the third flag. For accounts the installation of one of the flag bits, that is, by assigning a binary value of "unit" to the corresponding bit of the evaluation program is indicated on the corresponding adjoint extension part. In the top example of a code format all three bits 1, 2, 3 flags are set to "zero"so that the program handles the initial part of the message in this format and then no other data is no longer reads from this message. Shown below is the format of the data shows the bit 1 of the first flag is set to "unit", which indicates that it is followed by the extension portion B1. If bit 1 of the first flag and bit 2 of the second flag is set to "unit", as shown in the middle example, followed by two extension parts B1 and B2, and part B1 should always be in front of part B2. The order of the extension parts is skipping one extension part, as shown in both the lower examples. Thus through the use of flag bits can display a number of different data formats respectively from a common initial part and a number corresponding to the number of bits of the flags of additional parts, and the extension part, in principle, can include multiple data fields in a strictly defined sequence.
Figure 2 shows another form of execution of data formats according precede the him prior art. This example is similar to the structure provided in the draft standard RTCM 3.0. Each data format has a fixed first code 4, which is the initial part of the data format. This code is followed by several data fields C1, C2, and C3, the number and order of which may vary for each data format, in particular, some data fields may also be repeated, for example, when the same blocks of data from different satellites in the case of differential GNSS system are transmitted via a single control station.
Figure 3 shows two groups of data formats, which are identified on the basis of their code 4. From these data formats version 0001, 0002 and 0003 are known and therefore can be directly processed and formats 0004 and 0005 data are re-introduced and therefore, in previous devices, which do not account for these data formats in its software, not amenable to direct treatment. Generally, in this special case is not amenable to direct processing formats 0004 and 0005 data consist of data fields, which in principle can be processed by the device or existing software. In the General case, the corresponding sequence of data fields is unknown, so that can't be made no identification and evaluation.
Figure 4 illustrates the first is the possibility of using measured field data are not amenable to direct the processing of data formats in Figure 3. If the device has information about the sequence of the data fields that are not amenable to direct the processing format 0004 data, by lowering or cutting data following the field data C1, can be treated as a known format 0001 data.
Figure 5 explains the second possibility of using measured field data are not amenable to direct the processing of data formats. Beyond the immediate processing format 0005 data, after removal of the field C3 data can be rearranged in such a way that it will fit directly processable format 0002 data. If the sequence of data fields that are not amenable to direct the processing format 0005 data are known, for example, when receiving a data format of the evaluated field data can be stored intermediate image in the storage medium and then read from a storage medium in the order of the corresponding directly processable format 0002 data. In relation to the processing software this is then directly processed format 0002 data.
Figure 6 shows the representation of the third possibility, similar to that shown in Figure 5, for the use of estimated data fields that are not amenable to direct the processing of the format of the x data, when not, in General, is no clipping of the data fields, however, are not amenable to direct the processing format 0005 data after reordering directly in the processed format 0003 data can be used fully. Thus, such is not amenable to direct processing format 0005 data can be displayed differing directly processable format 0002 or 0003 data.
Fig.7 shows an example corresponding to the invention reference directory with direct indication of the sequence of data fields is shown in Figure 3 example of data format. The data formats described line by line. In the first field of the string specified encoding format of the data, which in this case is carried out using a four-digit number. Then follows a continuous indication of the data fields in their sequence in the structure of the data format. Alternatively, when the knowledge of bit patterns known data fields may also be provided for distribution by regions of memory, internal to hardware and software tools. Missing data fields or reached the end of the data format is indicated, specifying field of "00" data. Selected presentation 7 stems reasons of clarity, and determines not necessarily required in a reality format podlasek the transfer control catalog. When transferring such reference catalog, due to transfer of the volume data, it is recommended to compress the amount of data by reducing the unused rows or columns. For example, after each complete description of the format of the data can be transmitted corresponding indicator (end sequence) to end of line. An alternative can also be applied to other suitable methods for compression or transfer control catalog.
On Fig shows the first group of directly processed formats 0001-0004 data and the second group of not amenable to direct processing formats 0005 and 0006 data.
Figure 9 presents the corresponding invention reference catalog for shows for Fig groups of data formats direct indication of a sequence of data fields. Description not amenable to direct processing formats 0005 and 0006 based on the changes in relation to known and directly processed data formats. The first line in the first field ID "0005" of the corresponding data format. Following both fields in this row show that the sequence of data fields in the data format conforms to the following one behind the other sequences directly processed formats 0004 0002 and data, moreover, is in the General case, one field data C1 in the end formed of known formats data sequence must be again removed. The need for this is indicated by the indication "01" in the last field of the line. Thus, in this example, the instruction set is known and directly processed data formats according to your code in the sequence, starting from the left, while specifying want to delete data fields is at the end of the string, starting from the right. The second line shows the same indication for format 0006 data. Here not amenable to direct the processing of the data format is a combination of both directly processed formats 0002 and 0001 data.
Along with the measured data fields, not amenable to direct the processing of data formats can also meet new and therefore not measurable data fields. Figure 10 schematically illustrates the manipulation is not measurable data fields with application and without application data directory. Shown are not fed directly edit the format 0007 data. Top marked with this symbol And option provides for the allocation of the unknown and not measurable data fields in the device. When the message is received from the reference catalog retrieves the sequence of data fields, and at the time of admission or during subsequent evaluation of the fourth data field strobiles or not is read from the means x is anemia, so the sequence of data fields that are no longer contains not measurable field C4 data. This sequence corresponds then directly processed format 0002 data. Bottom marked with this symbol, option indicates the use is not amenable to direct assessment of the field data by C4 catalogue applications 6 data. In this directory 6 data saved information, which allows the device to use the data contained in not measurable data field.
Figure 11 shows a schematic representation of such corresponding to the invention of the catalog data to determine data types. The data directory contains line-by-line definition data types. Here, for example, the first line defined data type "BIT". The designation indicated in the first field. The second field is the number of bits in the third field is the minimum and the fourth field is the maximal possible value for the data type. In this case, the data type "BIT" is a binary data type with a length of one bit and with the possible values "0" and "1". This type of data may, for example, be used as a flag. The next line is selected, for example, the data type UINT16". In this case we are talking about the type of data with a length of 16 bits, which includes the range of values from "0" to "65535". In the third and fourth rows of the x follows the definition of the data type "INT16" and "INT17", which include negative values. Not used field in the data directory by analogy with Fig.7 and Fig.9 are set to "00".
Schematic representation of another corresponding to the invention of the directory data to define the data fields shown in Fig. In each row defined data field, and in this example, reference is made to the data types defined in figure 11. The first line is defined field "01" data. It is of type "BIT" of data. The next field indicates the interpretation of the subsequent fields. If the flag is here set to "0", then follow the field with all possible values of the field values of this data type. By the value "1" as the flag indicates that the next two fields are respectively the minimum and maximum valid value of the data type. In this first line, followed by all possible values, which are based on the type of data include only "0" and "1". In the fields, these values are correlated respectively with the variable "CODE". In this example, this means that the current in the device variable "CODE" here can be read from the data format possible values "0" and "1", which here as an example, correspond to two different forms of code C/a Code or P(Y) Code" satellites of the GNSS system. As another example similar field on which the R-function indicator may also be the applicable system GNSS. In this case, you would be using the same data type with three possible values be indicated with "0" the GPS system, using the "1" system GLONASS and using the "2" - the GALILEO system. The second line is defined field "02" data. It has a data type of "UINT10", and on the basis of "1" in the third field you can recognize that in the fourth field specifies the minimum, and the fifth field is the maximum value of the data field. In this example, these values are assigned the value of a variable "ANT", which corresponds to the technical parameter height of the antenna.
Such data directory can be used, for example, to adapt the old devices that recognize only two systems (GNSS) and a rough division of the height of the antenna, also to data processing for more than two systems and more accurate unit antenna height. As for the specific number of systems, still the device is informed about the new field of data through the data directory. If the conventional designation of variables for the applicable systems, such as GNSS, there is, still, the device may catalog data extract that processed GNSS systems are indicated respectively by the first both valid values the field values of the data type or data fields.
If the antenna height may encounter situations when anime resolution increases, and as a unit height of the antenna is used to transmit 1024 values, and 4096 values. From the data specified in the data directory, you can now remove the lower and upper limits of the ranges of values so that it becomes possible correlation of new, more accurate values with values coarser, the former unit. In this example, it can be accepted that the former range is from "0" to "1023" and contains a division by 1024 values. A new data field contains the values from "0" to "2047", and applies the data type with 12 bits and, thus, corresponds to the division on 4095 values. Thus former program can work when it cuts off the top half of the field values in the assessment, as these values go beyond the original area. For the lower half should now be taken into account that respectively two values of a new scale correspond to the value of the previous scale. Thus the device must accordingly two interrelated values to be interpreted as corresponding to the previous value. For example, the values "0" and "1" in the new data field would be interpreted by the device in both cases as "0". Passed in the new data field is "2843" could not be processed and would lead to the error message or for use in the device, instead, the maximum possible value is I "1023". The prerequisite for such applicability corresponding to the invention the data directory is the appropriate accounting for such functionality in the development of the previous software.
In principle it is also possible to define data types and data fields in a way similar to data formats by specifying changes relative to the known and estimated data fields or data types.
On Fig shows a schematic representation of the relationship of data types, data fields and data formats. In catalogue 7' data follows the definition of data types, while the catalog of the 7 data defined data fields. Field 05 data found in the format 0008 data, may be found in catalogue 7 data, where it is defined as type UINT10 data. Specification this data type can be found in the directory 7 data.
In addition, data fields and their contents can be supplied with abstract symbols, such as identifying the sequence and sequentially numbered. New data fields with assigned new sequence can be written in the data directory, as shown in Fig. In this data directory identifies new, not measurable field 67 and 68 of the data on the basis of the evaluated fields 28 and 29 of the data. In the first line again is not entered under aldeasa assessment field 67 data based on the estimated field 28 data, for which, however, defined a new field values with values from 0 to 2400,000, and resolution of 0.002. Content definition data and subsequent processing of the data takes on the definition of the field 28 of the data. The next line defines the available change the field values and resolution for field 29 data by specifying the new, not measurable field of 68 data and related data region or permission.
Fig schematically illustrates an example of transmission control catalog 10 using a method corresponding to the invention. The base station 8 DGNSS system as the first device transmits when the communication reference catalog 10 to the mobile device 9 and theodolite 9' as the second device, located within the area of transfer.
Alternative or in addition, may also be periodic emission current control catalog or catalog data broadcast, so everything inside the receiving station can receive the directory. The following method is only sample only the possibility corresponding to the invention pass duplex transmission. You can also use the one-way transmission according to the accordance with the invention.
The software of the mobile device 9 is designed so that it can directly handle only format M9 data, while theodolites can only handle the format M9' data. In the next step, which is schematically represented in Fig, a data transfer occurs in the M8 format from the base station 8 system DGNSS second devices 9 and 9'. They take directly unhandled format M8 data and can help control catalog 10 to identify or to localize measured field data. Thereby directly processed formats M9 and M9' data can be selected and, therefore, the transmitted data can be used, at least partially.
Fig schematically illustrates the first theodolite 11 with other devices as an example of the system corresponding to the invention. The first theodolite 11 and at least one intellectual reflector 15 as the second device together with another theodolite 11' as the first device are integral parts relevant to the invention system, in which between all components is the exchange of information. The first theodolite 11 contains for this purpose, the tool 12 which is in conjunction with the computer as a tool for processing the payload 13 and means 14 storage built what about the first theodolite 11. At the beginning of the communication connection to another theodolite 11' broadcasts to all second devices support directory. This reference directory in the first theodolite 11 is taken using the 12 communication and stored in the tool 14 of storage. In then transmitted between devices data formats based on the reference catalog can be localized measured data formats, if necessary with the assistance of the transferred data directory, and the data they contain can be used. For this purpose, theodolite 11 data are means of 12 communication and estimated means for processing the payload 13. For this purpose, the means for processing the payload 13 refers to the reference directory stored in the tool 14 of storage. In this regard, there should be no distinction in respect of the implementation of assessment tools and data processing. Corresponding to the invention, the method applies to all based on the use of computational tools implementations, regardless of the specific form of embodiment of a software algorithm based on the circuitry, hardware or executable software.
The presented embodiments describe only examples of the respective implementations of the invention and therefore should not be treated as final and limit the invention. In addition, the special is ialist will be able to get the other corresponding to the invention of a form of execution, for example, with the use of alternative forms of data storage and data processing.
