The level of technology

Known detector, which during operation informs the operator about the presence and position in building constructions hidden objects, such as pipes, cables, fittings in walls, ceilings or floors. Known detector also has a wheel that allows you to move the detector along the surface of the investigated object for scanning or sensing of the object.

Disclosure of inventions

The subject of the invention is a detector device for detection and positioning (localization) hidden objects in the object under study, comprising a housing, guide means for providing directional movement of the detector along the studied object in at least one direction, and the output device.

Features manual detector to detect and determine the position of the hidden objects in the object under study, comprising a housing, guide means mounted on the housing to provide directional movement of the detector along the studied object in at least one direction of displacement, the measuring device for recording at least real the setting movement of the moving body, the control device and an output device for outputting information to the operator. In the proposed detector, the output device is located on the front side of the housing and is designed as a digital display, and a control device coupled with an output device configured to output at least one dimension, i.e. with the dimension of the distance values determined in the direction of movement, in the form of a generated electronic digital symbol, and with the ability to update the output value of the distance, carried out at least mostly synchronously with the change of the parameter of motion, and manual detector further comprises an input device and has the input mode with the ability to set through the input device point of reference with respect to which the determined distance value and the job reference point is possible without interrupting the process of detecting and determining the position of the hidden object.

The invention provides increased comfort control manual detector, allowing to display the distance information in an intuitive form. Due to the fact that the control device in combination with a display unit configured to display the distance value in the form of a generated electronic digital si the ox, can be achieved particularly quick and accurate perception of the operator information about the distance. This symbol may be displayed in a digital display such as an led display or LCD display.

Additional technical result achieved in the invention is to improve the speed and convenience of the layout of the investigated object simultaneously identify the hidden objects and determining their location. The presence of the input device allows the operator to abandon the use of additional auxiliary measuring instruments such as a ruler and/or marking means for applying a starting point. This point can serve as the starting point for determining distance values or label operating position, for example, the drilling point. For example, the operator can investigate using the proposed invention in manual detector reinforced concrete wall for positioning reinforcement bars and point selection drilling. He can choose the point of drilling in the place where the valve is not moving the detector from the wall and even while doing the detector on the wall, click on the governing body of the input device by specifying the point of drilling as a starting point (zero). Leading the detector on the wall, the operator can easily lay out further t is his drilling with a given step (e.g., every 20 cm, i.e. at points located at a distance of 20 cm, 40 cm, 60 cm and so on), which is achieved by the output distance values and update this value in the process of doing the detector. The operator will be able to ascertain these points of reinforcement. If any of the points of the drilling was on top of the valve, the operator can move it to the minimum safe distance from the valve, reset the output device by clicking on the governing body of the input device and setting the offset point drilling as a new starting point (zero), and continue the process described above.

A guiding means is preferably in the form of a wheel mounted on the case and allows you to roll the body in the direction of movement. Instead of such wheels or in addition to the guiding means may be in the form of the sliding surface of the housing, which serves to ensure that the sliding housing on the investigated object in the direction of movement.

Under "dimension value" should be understood, in particular, the value of the dimension value, which corresponds to at least one unit. Unit in the preferred case refers to a particular system of units, such as the metric system or the English system of units. If the operator gets zachariassen, the unit can be used with them. If the correspondence between the unit and the distance value is for the operator unambiguous, for example, if the unit specified by the operator from specifying the units can be waived.

The presence of a measuring device for registering at least one parameter of motion when moving the enclosure, and that the control device is coupled with an output device configured to update the displayed value of the distance, carried out at least mostly synchronously with the change of the parameter of motion, allows to achieve a particularly high level of comfort control.

Under "parameter of the movement" should be understood, in particular, the dimension or metric by which you can determine certain characteristics of the movement of the housing relative to the studied object, such in particular as the length of the path or direction of movement. To register the setting movement of the measuring device can be used a variety of methods. Check parameter can be, for example, optomechanical means, for example, on the principle of optocoupler or photoelectric barrier. In addition, you can apply optical method, analyzing the structure of the surface is investigated object to register the movement direction and/or length of the path by moving the enclosure, for example, with the aid of the measuring transducer on the charge-coupled devices. You can surface to cover, and for accurate surface analysis can be applied laser beam. Can also be used to check parameter of the motion of an electron method, in particular, with the use of radar signal. If the detector is to detect and determine the location of hidden objects made using the radar method for registration of option movements is possible to additionally use a radar device used for determining the position of objects.

In a preferred embodiment of the invention, this distance depends on at least the length of the journey of the corps in the direction of movement, which can be achieved particularly intuitive perception of distance. This path can be a path taken by the body in the direction of movement. In another embodiment, the path may be a path, in which case you want to move and which is defined, for example, by the operator. In addition, the distance may be the distance between two detected hidden object or between two preset operator reference points (reference points), for example by drilling points.

In addition, to detect and determine the position of the hidden objects before agemy in the invention of the handheld detector may be a detector device, made with the possibility of collecting information on research results of the studied object, and has the logging mode to create a database in which information about the results can be correlated with the distance value. This makes it possible to achieve a particularly high flexibility in the application of the detector, if, for example, to prepare a report on the status of the investigated object, after which measurements can also be used for other applications.

It is therefore proposed to provide a handheld detector storage device for storing at least a database, which can be achieved particularly quick and easy database creation or quick access to the information contained therein.

In a preferred embodiment of the invention, the output device may have an interface for issuing at least distance values in external to the housing, the processing unit of output, due to what can be achieved with high flexibility analysis information about the distance. This interface is preferably designed for wireless transmission, such as, for example, the data interface via infrared technology or interface data transfer via Bluetooth wireless technology.

Preferably, the detector had an input mode of vozmojnostyami distance, specifies the path to which you want to move the body. This makes it particularly easy and accurately move the housing to the desired position. Enter the distance may be the path that must pass the detector. This path and enter the distance may vary on a length value that depends on a certain size, particularly the width of the housing in the direction of movement. While the path to which you want to move the detector can be set automatically based on the entered distance.

A particularly simple and intuitive control detector can be achieved if to detect and determine the location of hidden objects proposed in the invention of the handheld detector includes a detector device configured to collect information on research results of the studied object, and the control unit is configured to set the reference point to determine the distance value on the basis of information on research results in at least a partially automated mode. It found the hidden object, you can automatically match the zero point for determining distance values.

Other advantages of the invention discussed in the following description of the invention. Signs izobreteniya in the following description, the claims and the drawings, in some combination with each other. The expert in carrying out the invention will be able to use these features individually or jointly with other rational combinations.

The implementation of the invention

Figure 1 shows the detector 10, comprising a housing 12 made in the form of a shell to accommodate the internal components. It is applied to the object under investigation 14 made in the form of a wall. The housing 12 is fixed to the arm 16, for which the detector 10 can keep the operator. On the front side 18 of the housing 12 posted by device 20 output for outputting information to the operator and the device 22 is input to the information input by the operator, with a group of control buttons. The device 20 o contains unit 24 display, made in the form of zhidkokristallicheskogo (indicator). The device 20 output during operation of the detector is controlled by the device 26 controls. In addition, the housing 12 is installed directing means 28, is designed with four wheels in the position shown adjacent to the surface 30 of the investigated object 14. In the area of the side surfaces 32 and 34 of the housing 12 there are two such guide means 28, which are oriented perpendicular to the direction of the main length of the body 12, presents its Central axis 36. Directing means 28 are paired axes 38 and 40. Axes 38, 40 are held in the direction of the main length of the body 12 on either side of the Central axis 36. Directing means 28 are used for directional movement of the housing 12 in the direction 42 move parallel to the surface 30 of the investigated object 14. Direction 42 are oriented perpendicular to the moving direction of the main length of the body 12.

When moving the housing 12 by the operator of the detector can scan or probe, the analyzed object 14 to detect and determine the location of hidden objects that lie beneath the surface 30 and invisible, for example, a hidden object 44. For this purpose, the detector 10 has a detector device 46 located beneath the unit 24 display and is shown in figure 2. The interaction device 26 controls directorymountain.com 46 and the device 20 conclusion in more detail in figure 2. The detector device 46 includes an emitter for emitting a measuring signal 48 in the form of, for example, a radar signal, the UWB signal, inductive or capacitive measuring field, a receiver for receiving the measurement signal 48 after its interaction with the object 14 and the processing unit (not shown) for analysis of the measuring signal 48.

The detector 10 can also display information about performed by the operator moving the housing 12 about the examined object 14. For this purpose, the detector 10 includes a measuring device 50 with two transducers 52, made in the form of displacement sensors. Each measuring transducer 52 is associated with one of the axes 38, 40 (see figure 1). Transducers 52 are notched wheel fixed on the plot axis 38, 40, at least one emitter for generating a light beam and a receiver (not shown) for receiving the light beam. Each measuring transducer 52 registers on the principle of optocoupler or photoelectric barrier parameter 54 motion corresponding to the increment of the path defined by the rotation of the gears caused by the movement of the body 12. This principle is known in the framework of this description is not explained in more detail.

On the basis of the years of this parameter 54 movement, transmitted in the form of an electrical signal in the device 26 controls, you can get information about moving the housing 12. In particular, through the device 26 controls you can define traversed by the housing 12 segment of the path and/or direction of its motion. Due to the registration of the two motion parameters performed in the case of two independent from each other axes 38, 40, it is possible to achieve high-accuracy determination of the traversed path. You can, for example, to correct errors, for example, due to nonlinearities, due to the structure of the surface 30.

Assume that the operator scans the investigated object 14. It places the detector 10 to the edge 56 of the investigated object 14, corresponding, for example, the corner of the wall and moves it in the direction 42 move to a distance of 58, representing the length of the path. Shown in figure 1 the position detector 10 detector device 46 is detected hidden object 44 in the test object 14. When the detector device 46 after the analysis of the measuring signal 48 displays information 60 on research results, in particular the position 60.1 center hidden object 44 relative to the housing 12, the width 60.2 hidden object 44 and the depth 60.3 occurrence hidden object 44 in the test object 14, which is indicated by block 24, the display symbol 2 hidden object. On the basis of information 60 on the results of the study device 26, the control generates the control signal 64 to control the operation of device 20 to output the result on the display 62 of the hidden object. In addition, in this embodiment of the invention is shown another symbol 63, which corresponds to the Central axis 36 of the housing 12 and provides a particularly simple possibility of the operator's perception of the position of the hidden object 44 relative to the Central axis 36. In the present example, the center of the hidden object is located on the Central axis 36. In another embodiment, for the image of symbol 63 on the housing 12 on the edge of the block 24 of the display can also be applied to the label.

When moving the detector 10 in the position shown in figure 1, the measuring device 50 during the movement of the detector records parameters 54 of movement corresponding to the increment of the path of the guide means 28. Settings 54 motion is transmitted to the device 26 controls. Based on these parameters, 54 movement device 26, the control generates the control signal 66, which is a visual representation of the detected hidden object 44 unit 24 display is provided in accordance with the current location of a hidden object 44 relative to the housing 12. When this symbol 62 hidden object moves within the x unit 24 display, made in the form of a liquid crystal display, respectively, the fixed increment path. To do this, select a specific correlation coefficient, in which the measured path, for example, 1 cm corresponds to a specific number of pixels of the block 24 of the display. This allows us to depict the scale of the investigated object 14, and, if necessary, and hidden objects. For example, you can display the area of the investigated object 14 extending beyond the width of the housing 12. In particular, at block 24 of the display can scale to display all of the investigated object 14. In addition, you can also display the characters, the width of which on the block 24 of the display corresponds to the actual width of the corresponding detected hidden object. This allows you to display the exact size of the image region of the investigated object 14, closed at least a separate section of the surface of the housing 12. The correlation coefficient, which determines the ratio between the number of pixels by the detector can be set during manufacture of the detector or in the preferred case - can be installed by the operator in operation.

In addition, the device 26 control determines the distance 58, passed by the appropriate body 12 way, in the units specified by the operator or the manufacturer, in this when the ore in centimeters. In this example, the detector 10 operates in a mode in which the distances are defined relative to the Central axis 36 of the housing 12. The device 26 controls adds half the width of the housing 12 and the resulting distance 58, resulting in a gain value 68 a distance corresponding to the distance 70 between the starting point traveled stretch of road, in this case, the edge 56 of the object, and the Central axis 36. This value 68 distance and electric control signal 72 are fed into the device 20 output. The control signal 72 controls the display values 68 distance through a digital symbol and symbol 74 units. In other modes, in contrast to the above, a value of 68 distance can be defined relative to the edges 76, 78 of the housing 12. If, for example, to bind a dimension to the face 76, the displayed value 68 distance will correspond to the distance traveled 58. Used unit of measurement, such as millimeters, centimeters, meters, etc. can be set by the operator using the device 22 to input and display unit 24 display control surfaces. The display unit can be performed by symbol 74 units, and/or may display scale with defined unit divisions, to determine the value 68 distance, revniv symbol 62 a hidden object with scale. There is also a setting mode, canceling the display unit, which frees up space to display other information, in particular information about the results of the research object. Value 68 distance can also be displayed only at the request of the operator, for example, when you enter the corresponding command from the device 22 to enter. In automatic mode, the value 68 distance is displayed continuously, resulting during the movement of the housing 12, the detector may constantly inform the operator of the distance travelled 58. For this performed by a device 26 controls the update, or updating, the output 68 of the distance continuously correlated with the change in time of the parameters 54 movement. Another option configuration mode provides the possibility of relating displaying on the display the values 68 distance from the beginning of the movement of the detector 10.

Further, the operator can be informed of the distance at which the detected hidden object 44 is relatively edges 56 of the studied object or another operator specified reference point. This is particularly easy to implement, providing a continuous indication of the value 68 distance and symbol 63. In the example shown in figure 1, we show the value of 68 distance corresponds to the distance from the center of the hidden is bhakta 44 to edge 56, i.e. the distance of 70 as the center of the hidden object 44 is located on the Central axis 36. In addition, the moving body 12 from the position shown to the left or right, you can easily determine the distance between the left and the right edge of the hidden object 44 and the edge 56 of the investigated object 14. When this symbol 62 corresponding to the hidden object 44 is moved within the block 24 of the display, respectively. The housing 12 is moved up until the symbol 63 is aligned with the left or right edge of the character 62 hidden object. In this case, the value 68 distance corresponds to the desired distance. Instead of a continuous display values 68 distance, or in addition to it can be at the operator's option at any time to show the distance from the hidden object 44 to the edge 56 of the investigated object, measured from the left or right edge of the hidden object 44 or from its center.

Another mode of operation of the detector provides the ability to display values 80 distance corresponding to the distance 82 between the two detected hidden object. This feature is shown in figure 3. Assume that the operator moves the detector 10 from the position shown in figure 1, moves in the direction 42 of the move. The detector detects another hidden object 84, which is signaled by the appearance on the display of another symbol 86 hidden object. Simultaneously, from which the representation of symbol 86 hidden object displays the value of the 80 distance characterizing the distance 82 between the hidden object 44, 84, in certain units. This is due to the fact that the detection of the first hidden object 44 device 26 management on the basis of relevant information 60 on research results corresponding to the detection of the first hidden object 44, sets the reference point to determine the distance 82. In this case, the length of the path traveled by the housing 12 when it is moved continuously determined by the device 26 controls based on the settings 54 motion until you found the second hidden object 84. Upon detection of the second hidden object 84 defining the length of the path is terminated. Based on the path length and information 60 on research results, in particular the width of the respective detected hidden object 44, 84, it is possible to determine the distance 82. This distance 82 between hidden object 44, 84 in this example, is the distance between facing each other with the edges of the corresponding hidden objects. In another embodiment, it is possible to determine the distance between the centers of the hidden objects. After determination of the distance 82 device 26 controls generated control signal for indicating the distance 82 in the form of values 80 distance and the corresponding unit of measurement.

The starting point for determining another value is FL 88 distances in another mode of operation can be set by the operator regardless of the detection of the hidden object. This feature is presented in figure 4. If the body 12, in particular its Central axis 36 or faces 76, 78, is in a position corresponding, for example, the position of the point of drilling, the operator, acting on the device 22 to enter, you may set point 90 relative to the figure schematically presents a cross). Regarding this point, 90 count when moving the housing 12 in the direction 42 of the move is determined and continuously displayed on the display 88 of the distance corresponding to the distance 92 between the point 90 of reference and the Central axis 36 of the housing. This mode allows, in particular, to renounce the use of additional measuring device, such as a measuring ruler to measure the distance 92. Point 90 count can be set to do this without interrupting the measurement process performed by the detector device.

Another mode of operation of the detector is seen in figure 5. In this mode, the operator using the device 22 input and control surface, the display unit 24 displays, introduces a certain distance 94, representing the length of a path on which the detector must be moved in the direction 42 move to achieve the desired working position 96, for example, the drilling point. In this case, the device 26 control sets the current position of housing 12, shown in figure 5, in private the tee its Central axis 36, as a starting point, or reference point. When moving the housing 12 on the basis of parameters 54 movement registers the path, which is compared with the distance 94 that allows you to determine the length of the rest of the journey in the form of values 98 distance that appears on the display. Upon reaching the desired operating position 96, namely, when the working position 96 will be on the Central axis 36, may be issued an optical signal, for example, by including a light indicator or a corresponding display on the unit 24 display and/or audio signal. When moving the housing 12 may display the length of the rest of the journey. In this example, the desired position, as a possible option may be such that the operating position 96 is adjacent to the face 78 of the housing. In this case, as described above, enter the distance 94 between the Central axis 36 and a work position 96, the distance 94 is different from the path on which you want to move the housing 12, the half width of housing 12.

In addition, the detector 10 has a logging mode, shown in figure 2 and 6. In this mode, in particular, creates the base 100 of the data, in which the distance information obtained by the device 26 controls based on the settings 54 motion, correlated with information 60 on research results. This database 100 data is redstavlena figure 6. In the left column is written corresponding to the distance information, in particular the specific location of the object on the surface 30 in the form of values 102 distances showing the dimension. This value 102 distances, it is preferable to determine from the edge of the investigated object 14 in the direction 42 of the move, but it can also be determined from the given operator point of reference. With a value of 102 distances correlate information 60 on research results, in particular the type 60.4 detected hidden object marked in the drawing by letter, a depth 60.3 its occurrence in the studied object 14, width 60.2, etc. Shown in the drawing values serve as an example for explanation. In addition, with a value of 102 distance can be correlated information "hidden object not found". This database describes the topography of the investigated object 14 and allows to make a conclusion about the state to be processed is examined object 14. On the basis of 100 data, you can easily find the specific location of the investigated object 14, it is possible to determine whether there is in this place of the investigated object 14 hidden object. You can also search for a particular hidden object, such as wiring, and can be set in any place or places where the studied object 14 find the camping this hidden object.

The base 100 of the data can be saved by working with the detector 10 in its storage device 104 (Fig 1 and 2). Base 100 data compiled by device 26 control to move the housing 12 on the basis of parameters 54 traffic and information 60 on research results. After performing the measurement base 100 data can be transmitted to the external device 106 data processing. In this example, the device 106, data processing is executed in the form of a PDA (personal digital assistant). In another embodiment, the processing unit may be in the form of a laptop or mobile phone. To establish communication with the device 106, the data processing device 20 output provided by interface 108 (see also figure 1 and 2), which is made in the form of interface Bluetooth communication. Bluetooth is an industry standard IEEE 802.15.1, developed by the Institute of electrical engineers, and electronics on a wireless (radio)communication between devices over a short distance. Instead, the interface may be in the form of interface data transfer via infrared technology. In addition, you can use the interface for data transmission by cable, such as a universal serial bus (USB). After performing a measurement by operator data can be transferred into the database 100 is data. You can use the logging mode in which the value of 102 distance and information 60 on research results without intermediate storage in a storage device 104 are transmitted to the device 106, data processing, and database 100 data created in the internal memory device 106 of the data processing. This data transfer is carried out each time using the interface 108 in connection with the device 26 of the control.

Setting up a database of 100 data can be performed continuously during scanning of the investigated object 14, with each position of the surface 30 is put into correspondence information 60 on research results, or entering data into the database 100 of data may occur upon detection of a hidden object.

The detector 10 also has a calibration mode in which the device 26 of the control, in particular, is calibrated to determine the dimensional values 68, 80, 88, 98 distance based on the settings 54 movement. In this mode, the body 12 is moved at a known distance operator, which can be entered using the device 22 to enter. In another embodiment, the detector 10 may be designed so that regardless of the type of surface 30, the pressing force applied by the operator to the housing 12, the wear of the guide means 28, speed, etc. to determine for a certain length of the path od is about the same distance value.

The above-described modes of operation, as well as other programs to configure the detector 10 and the interaction device 26 controls the devices connected to it, for example, programs for processing parameters 54 traffic and information 60 on research results, and for generating control signals 64, 66, 72, is stored in the storage device 110 of the device 26 of the control.

SUBSTANCE: invention relates to marine geoelectrical exploration using controlled artificial sources of electromagnetic field. Using a dipole source, an electromagnetic field is generated inside the analysed medium by sending rectangular electric pulses with intervals in between into the medium. Geometrical probing is done along the profile during the current pulse, and probing on transient processes is done during the interval. Measurements are taken using measuring apparatus mounted on the seafloor, consisting of five electrodes: a central electrode with four others around it on corners of a square, two opposite sides of which are parallel to the axis of the profile. During the current flow period and intervals between current pulses, the second electric potential difference between external electrodes and the central electrode, as well as the first electric potential differences between three pairs of external electrodes is measured. When the dipole source passes through different points, there is provision for equipotentiality of a closed line passing through four external electrodes of the measuring apparatus thereby eliminating the horizontal component of current density in each probing point inside this line. Values of the measured electric potential differences are used to calculate three sets of standard interpreted electrical parametres which are not subject to lateral effect of three-dimensional geological non-uniformities located outside the probing point. Using the derived parametres, the model of the medium is found and time sections of this model is constructed on electroconductivity of elements of the medium, induced polarisation coefficient and decay time constant of induced polarisation potential differences.

EFFECT: elimination of distorting lateral effect on probing results, which allows for deep sea delineation of hydrocarbon accumulation with high contrast.
