The invention relates to a circuit control device, a storage device controlled by a control device and at least two measuring devices connected to the control device and recording the measurement results due to temporal correlation in the same time unit as well as transmitting them to the control device.

Such schemes are used, for example, in the field of protective equipment. They serve, for example, for registration and analysis of the current and voltage lines or power lines or transmission system to detect invalid or dangerous operating conditions and, if necessary, prompt disable parts of plants to minimize, and if possible prevent damage.

As for determining the defect or failure in varying degrees, must take into account not only current measurement results, but, in addition, the previous time the old measurements, the measurement results must be retained at least for some period of time in the intermediate memory. Thus from the point of view of the subsequent analysis of failures in most cases, it is desirable that the storage period was perhaps the largest and constituted, for example, a few days. However, the longer the time period, the bigger number is the number of measurement results, to be processed, and the longer the sampling time of the individual measurement results contained in the array is measured, and, figuratively speaking, the hidden values. In standard systems, data banks, established on a commercial basis, although they without problems provide the possibility of using even a very large dataset, the time of their selection for use, for example, in the field of engineering protection of power plants, as determined by the inventor, in the presence of large amounts of measurement results in most cases too large.

The basis of the invention in accordance with this laid the task of creating a schema for a long period of storage and at the same time, the minimum sampling time of the recorded measurements.

This task is solved on the basis of the above-mentioned type with distinctive signs of paragraph 1 of the claims. Preferred embodiments of the invention are given in the dependent claims.

In line with this, according to the invention provides that the control device was designed in such a way that it recorded the measurement results of at least two measuring devices in the storage device as a logical matrix with rows and columns, what to eat each measurement device it took an individual column, in which would be recorded measurement results of the respective measuring device, and to a new measurement result of each measurement device was, accordingly, in the next line of the corresponding column, and to record measurement results of different measuring devices line is correlated, for which the results of measurement of various measuring devices belonging to one and the same time the measurements are recorded in the same line.

A significant advantage of the circuit according to the invention is seen in that the recorded measurement results can be accessed relatively quickly. This is because the measurement results recorded structure taking into account the time dimension. Namely, if the processing module, let this be a hardware processing device or application software software that wants to access the old time to the measurement results, they generally will not request a separate measurements at different time points of measurement and the units of the measured values from the measurement results of different measuring devices for a certain period of time. Because provided according to the invention structured recording of results is serenia all the measurement results, referring to one and the same time of measurement or to a specific time interval measurement in a storage device logically recorded directly next to each other and each other, to request measurement results, there is no need to consider and to view the entire available data set from the measurement results; on the contrary, it is enough to transfer the relevant memory area in the intermediate storage device, such as device control, and continue to use only this relevant memory area. Due to this sampling time requested or required measurements will be reduced considerably. In other words, the invention thus uses the understanding of the fact that in practice, especially in technology protection and transfer blocks of data are sampled, not arbitrarily, but according to a specific pattern related to the time dimension. This position is the starting point of the invention, when the expected or likely the query sample is taken into account during data recording, allowing accelerated subsequent polling process.

Preferably, valid or free memory area for recording the measurement results is limited in order to allow other devices, such as, e.g. the, the processing modules and the like, to have at its disposal sufficient memory within the control unit. In accordance with this according to a preferred variant implementation of the scheme is preferable that the number of rows of the matrix was severely restricted in advance a specified maximum number and to the control device after the description of the last row of each column of the matrix returned back to the first row of the corresponding column and carried the appropriate next measurement result corresponding measuring device in the first row of the corresponding column.

Although the measuring device should always record and record the results of their measurements at the same points in time, so they are always identical time points, measurements still can't reach the controls at the same time. Namely, if one of the measuring devices installed is clearly closer to the master than other measuring device, the measurement results of the spatial closer the measuring device, as a rule, reach the controls faster than more distant measuring device. So simple and therefore advantageous manner to ensure that all the measurement results, advancing to the device the VA management all were recorded in the proper place matrix, or as prescribed matrix element, according to a preferred variant implementation of the scheme provides that the control device was designed in such a way that it was first applied to the array of pointers, in which each of the measuring devices and thus, for each column of the matrix listed information, directly or indirectly specifies what string should be recorded corresponding to the next measurement result.

Since all the measurements in time are recorded line by line, the individual recording the absolute time measurement, i.e. time of day, upon registration, each measurement result is not required. Moreover, according to a preferred variant it is sufficient if the control device was designed in such a way that it is, accordingly, remembered absolute time only for a subset of rows, at least, however, for one (for example, for the i-th row) row of the matrix, which specifies the point in time of measurement of the measured values recorded in this line. For example, for each column of the matrix is fixed, a single absolute time. In this case, the moments tj measurement time remaining measurements in other rows of the matrix are defined simply, dlaczego multiplied the difference between the line numbers and the time interval of registration of measurement results and added absolute time ZA, for example, according to

tj=(Zj-Zi)*T+ZA or

tj=(Zj-Zi)*1/f+ZA,

where Zj is the j-th row of the matrix, Zi is the i-th row of the matrix, for which a fixed absolute time ZA, T is the time interval between two consecutive time points of measurement specified measuring devices, and f is the period of measurements, the specified measuring devices.

Preferably, the control device is designed so that it overwrites the recorded absolute time to a new absolute time every time, once in the string will be logged measurement result at a later point in time measurement is compared with the recorded time reference.

Particularly preferably, in the array of pointers individually for each column by direct or indirect instructions were recorded the following: the string in which each listed next measurement result of the corresponding column of the matrix or the corresponding measuring device, as well as the absolute time indicating the time of the last recorded measurement of the dimension of the corresponding column. Under the indirect instruction in this connection, it should be understand from which a conclusion can be made about the line and/or about the time indication: for example, can be specified last line in which you have entered the last measurement result of the Il is, instead, a new string in which shall be entered a new measurement result.

In addition, the invention relates to a method for recording measurement results of at least two measuring devices.

In order in this way to ensure that ensured a large interval of time memorizing and together with the minimum sampling time of the recorded measurement results, according to the invention is provided, so that the measurement results of the measuring devices were recorded with a time correlation and recorded in the storage device as a logical matrix with rows and columns, with each measurement device is allocated an individual column, and this column records the measurement results of the respective measuring device, and a new measurement result of each measuring device is inserted in the next line of the corresponding column and recording the results of measurement of various measuring devices is carried out with a time correlation, for which the results of measurement of various the measuring device pertaining to one and the same time the measurements are recorded in the same line.

As for the advantages of the method according to the invention and the preferred embodiments of the method, it can be what about the reference above in connection with the scheme according to the invention.

In addition, as the invention is considered a control device.

According to the invention in respect of such control devices, provided that it is done in such a way that it recorded the measurement results of at least two measuring devices in the form of a logical matrix with rows and columns, with each measuring device, it allocates an individual column, which records the measurement results of the respective measuring device, and a new measurement result of each measuring device is inserted, respectively, in the next line of the corresponding column and recording the results of measurement of various measuring devices with line-by-line correlation, for which the results of measurement of various measuring devices belonging to the same point in time dimension written in the same line.

As for the benefits of the control device according to the invention and the preferred embodiments of the device management, you can refer to above in connection with the scheme according to the invention.

Below the invention is explained in more detail based on the embodiments, as an example

Figure 1-6 reasons of clarity, for identical or comparable components are constantly used the same position.

Figure 1 shows the device 10 management, United network 20 data with three measuring devices PMU1, PMU2 and PMU3. In the case of three measuring devices PMU1, PMU2 and PMU3 it is, for example, about measuring device pointers (so-called Phasor measurement Units), which measures the magnitude of the currents and voltages are not shown in figure 1 transmission line and forming the corresponding results of the measurement directions. the results of measurement of pointers together with the appropriate time ti time dimension in blocks D1, D2 and D3 of the data transmitted over the network 20 to the data transmission device 10 of the control.

Further assume that the measuring device PMU1 in their blocks D1 data transmitting device 10 controls the measurement result pointer voltage in the following briefly referred to as a pointer V11 voltage, and the corresponding measurement result of current - in the following briefly referred to as a pointer I11 current. Blocks D2 data of the second measuring device PMU2 contain, respectively, the index voltage V21 and the pointer current I21. The third measuring device PMU3 passes in their blocks D3 data two pointer V31 and V32 voltage, and one pointer I31 current.

With the device 10 of the control are connected to two modules 60 and 70 of the handle connected to the device 10 management as a separate hardware-implemented processing device via electrical connecting lines.

In addition, device 10 controls connected storage device 100 with the Bank 110 data, in which the device 10 of the control records the measurement results, i.e. the directions of voltage and current, three measuring devices PMU1, PMU2 and PMU3.

The circuit according to figure 1 may be operated as follows.

The device 10 management analyzes the blocks D1, D2 and D3 of the data obtained from the three measuring devices PMU1, PMU2 and PMU3, and developed the thus pointers V11, V21, V31 and V32 voltage, as well as pointers I11, I21 and I31 current. Because the blocks D1, D2 and D3 of the data, respectively, are also appropriate times ti time measurement device 10 controls can also be set for each measurement result of the pointer corresponding to the time dimension.

10, control passes to the corresponding results of the measurement of pointers directly at the disposal of both modules 60 and 70 processed so that they can immediately apply to the relevant measurement results before they will be written to the storage device 100. Thanks to this mode achieves a significant gain in time, as the same modules 60 and 70 processing will be able to resume the direct processing of the current results of measurements of pointers and they don't have to read them from a storage device, spending a relatively long time.

However, the device 10 not only supplies the modules 60 and 70 processing the measurement results of pointers, and sequentially writes them to the Bank 110 data. However, the record data Bank 110 data structure. Specifically, all the measurement results of pointers referring to one and the same time ti time measurement, logically written to the same prompt, mA the Siwa matrix data storage device - in the following briefly referred to as the matrix. Thus the corresponding column of the matrix shows which of the measuring devices PMU1, PMU2 or PMU3 belongs to the corresponding measurement result. The entry of the matrix is carried out, preferably, not only logically but also physically in a matrix form in the appropriate area of memory.

The matrix structure shown in detail in figure 2 and indicated by the position 200. It is easy to see that the pointers V11 voltage measuring device PMU1 listed in the first column S1 of the matrix 200. Pointers I11 current measuring device PMU1 listed in the second column S2 matrix 200.

Accordingly recorded the results of the measurement directions of the second measuring device PMU2 in columns S3 and S4, and the results V31, V32 and I31 measurement directions of the third measuring device PMU3 in columns S5, S6 and S7.

While recording the measurement directions in the matrix 200 ensures that all results of measurements relating to one and the same time ti time, was recorded in the same line. It is easy to see that in the i-th row Zi writes the results of the measurement points in time ti time, and (i+1)-th row Zi+1 - results of the measurement at time ti+1 time. The same applies to (ti+2)-that moment in time, captured in the line Zi+2.

Cu is IU, figure 2 shows a one-dimensional array 210 pointers, containing exactly the same number of columns as the matrix 200. Arrays 210 pointers for each column of the matrix 200, i.e. individually for a column, each time is recorded, in which the line Zj matrix 200, respectively, should be listed next measurement result. Thus, the array 210 of pointers allows you to ensure that the incoming measurements pointers relating to different points in time dimension added to their proper place inside the matrix 200. Below it will be explained in more detail in the example.

If we proceed from the fact that the first measuring device PMU1 established especially close to the device 10 of the control, the results V11 and I11 measurements pointers will arrive before the corresponding measurement results of pointers to other measuring devices PMU2 and PMU3. In the example shown in figure 3, where the incoming current measurement results of the pointers shown using vertical strokes. Thus, in the embodiment of figure 3 the results of V11 and I11 measurement directions of the first measuring device PMU1 has already received up to the time t6 to the time dimension.

The third measuring device PMU3 more removed from the device 10 of the control, so that the results V31, V32 and I31 of measurements of the decree of the oil will go into the device 10 management later respective measurement results of the pointers of the first measuring device PMU1. In the example according to figure 3 the results V31, V32 and I31 measurement directions are presented only until time t5, while at the time t6 to the time measurement device 10 management has not yet received any results of measurement of pointers.

The second measuring device PMU2 in the embodiment of figure 3 the most removed from the device 10 of the control, so that the measuring device has only the results V21 and I21 measurement of pointers until time t4 measurement.

But, despite the shift in the flow of the measured values of the pointers time, to ensure that each measurement result pointers constantly feel in their proper place inside the matrix 200, the first array 210 pointers is read. This enables the device 10 to control the admission of each new measurement result of pointers first determines in the array 210 pointers place, in which shall be entered corresponding to the next measurement result. If, for example, receive new results of measurement of the first measuring device PMU1, the device 10 management after reading the array 210 pointers will establish the following results V11 and I11 measurement of signs should be received in the seventh line Z7, since the measurement results are related to the time t7 to the time dimension./p>

Accordingly, the device 10 reads the array 210 pointers when you register new results V21 and I21 measurement of the second measuring device PMU2. In this case, the device 10 management determines that the new measurement results of pointers must be recorded in the fifth line Z5, as they are for the fifth time t5 to the time dimension.

New measurements of the signs of the third measuring device PMU3 appropriately recorded in the sixth row Z6, because they belong to the sixth time t6 to the time dimension.

As can be seen in figure 2, in the matrix 200 points t1-t6 measurement time in order to save memory, as such, are not recorded. Such moments ti time measurements through a matrix structure and is not necessary because the measurement results are recorded in the matrix 200 sequentially structured fashion. Because each row Zi recorded, respectively, only the measurement results at the same time ti time, this time for all of the results of the measurement matrix 200 is calculated simply, if known absolute time or absolute time of day the measurement of at least one row and if the measurement results of the three measuring devices PMU1, PMU2 and PMU3 correlated the time in one specific quantum or are equidistant in time. This will be illustrated in the following example.

If three measuring devices PMU1, PMU2 and PMU3, respectively, register a new measurement result every 25 milliseconds, for each row of the matrix 200, and thus for each measurement result can be computed absolute time tj measurement time or the time of registration of the measurement, for which the corresponding string value is parsed according to

tj=(Zj-Zi)*T+ZA

tj=(Zj-Zi)*25 MS+ZA,

where Zj is the j-th row of the matrix, Zi is the i-th row of the matrix, T is the time interval of 25 MS between two consecutive time points of measurement specified measuring devices PMU1, PMU2 and PMU3, and ZA - fixed absolute time measurements.

In the result it can be stated that the circuit according to figure 1 provides a very fast processing blocks D1-D3 of the data, as the device 10 management for a fast and efficient processing, on the one hand, immediately supplies the modules 60 and 70 processing the measurement results of pointers, and on the other, shall record the measurement results of the pointers in the device 10 management in a matrix form, providing quick access to all measurement results obtained for the same period of time. Namely, due to the unit, or packet, records of related results ISM is rhenium inside the matrix 200 relevant region data Bank or matrix for the survey can be copied into an intermediate storage device, implemented in the device 10 controls for quick access to all measurement results of the pointers stored in the relevant areas for appropriate processing. So there is no need to open the entire pot 110 data or the entire matrix, it is enough to open them only partially, so the sample corresponding to the desired blocks of data or measurements pointers markedly accelerated.

If the measurement results in the data Bank were not distributed in a matrix form, and arbitrarily, it would have to apply to the entire data Bank that in case of large amount of data Bank would be very time-consuming; this is evidenced by the following numerical example: if, for example, the measurement results recorded in 10-bit format, and the results of measurement 1000 measuring devices are logged every 100 MS and stored for 30 days, then the file size is equal to at 2.59 KB. If the measurement results were distributed in this file is unstructured, then the processing would have to deal with the whole file, which would require a powerful intermediate storage device, and a considerable amount of time reading. However, due to the recording of measurement results in a logical matrix form we know exactly in what area of the file you can find the results of measurement for measuring the certain period of time, so copy in the intermediate storage device and process have only this relatively small area of the file that is of interest.

In addition, by recording the measurement results in the form of a matrix is very simply achieved by limiting the size of the file or data Bank 110, which is "circle" account: this means that when the maximum number of rows from the first row of the matrix 200 according to figure 2 begins a new countdown, and recorded it the old content is overwritten. Thus, recording of measurement results occurs in cycles, and the measurement results of each of the preceding measurement cycle is overwritten by new measurement results corresponding to the current measurement cycle.

However, the function of the array 210 of pointers is when overwriting old data to show to what row of the matrix 200, the measurement results are relevant or related to the current cycle, and what is the row matrix of the recorded measurement results of the preceding cycle.

As for simple control over the recorded whether the results of measurement at a given point in time or not, according to the alternative implementation of the array 210 pointers along with the current number of rows can be written t is the train time of the last measurement result; this is shown in the example in figure 4: it is easy to see that along with the number of rows for the next measurement result is specified as the time of the last recorded measurement result.

Data recording can be carried out in a one dimensional array of pointers, as shown in figure 2 and 4; the alternative can also be used in a two-dimensional or three-dimensional array of pointers, as shown in the example in figure 5.

Figure 6 shows a second example of implementation of the scheme. In this example, the implementation of both modules 60 and 70 processing performed not as individual components, and how the software modules of the software, or application software running in the processor unit , device 10 controls. For the functioning of these modules software software no matter where they are physically stored; they can be stored, for example, inside the storage device 100 or any other storage device schema.
