TECHNICAL FIELD

[0001] The present application relates to the technical field of position identification, in particular to a spatial position identification method, system, device and storage medium. BACKGROUND

[0002] GIS equipment is widely used in power systems due to its compact structure, small footprint, high reliability, flexible configuration, easy installation, strong safety, strong environmental adaptability, and small maintenance workload. However, due to the fully sealed structure of GIS equipment, fault positioning and maintenance are more difficult, and the maintenance work is complicated. The average outage maintenance time after an accident is longer than that of conventional equipment, and the outage range is large, often involving many non-fault components.

[0003] Therefore, real-time or periodic detection of the operating state of GIS equipment using partial discharge monitoring devices or live testing devices can intervene in GIS equipment maintenance at an early stage of defects, which is an important means to prevent abnormal development of GIS equipment into faults. According to the technical specification requirements of the Southern Power Grid, partial discharge monitoring devices are required for GIS equipment of 220kV and above, and all GIS equipment needs to be periodically tested for partial discharge.

[0004] The spatial position of the partial discharge sensor is an important parameter for GIS equipment partial discharge anomaly investigation and positioning. The current technology obtains the position parameters of the sensor by manual measurement in the case of needing sensor position parameters for inspection, and then inputs the monitoring or detection device for analysis and calculation. When the sensor position parameters are needed to construct a sensor point distribution information map, manual drawing is required. Therefore, the sensor spatial position information has a large error and low accuracy. SUMMARY

[0057] This invention provides a spatial location identification method, system, device, and storage medium to address the current technical problem that, in inspection applications requiring sensor location parameters, sensor location parameters are obtained manually and then input into monitoring or detection devices for analysis and calculation; furthermore, when constructing sensor distribution information maps using these parameters, manual drawing is required. Therefore, the sensor spatial location information suffers from significant errors and low accuracy.

[0058] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0059] Please see Figure 1 , Figure 1 The flowchart illustrates the steps of a spatial location identification method provided in Embodiment 1 of the present invention.

[0060] This invention provides a spatial location marking method, applied to a location marking device, relating to a partial discharge ultra-high frequency sensor. The location marking device is connected to the partial discharge ultra-high frequency sensor. This method includes the following steps:

[0061] Step 101: In response to the received trigger information, measure the height data of each partial discharge UHF sensor.

[0062] It should be noted that the location identification device refers to the device installed on the partial discharge UHF sensor. The location identification device includes a power module, network module, clock module, storage module, laser positioning module, computing module, signal generation module, signal detection module, signal switch, high-speed cable interface, receiving antenna, and transmitting antenna. The partial discharge UHF sensor is a device that can quickly and in real-time identify power equipment with latent partial discharge defects, allowing power users to focus on detailed inspections of potentially hazardous equipment, greatly reducing the workload of power maintenance personnel and effectively preventing power grid equipment safety accidents.

[0063] In a specific embodiment, trigger information is sent periodically. When the trigger information is received, the system responds by measuring the height data of each partial discharge UHF sensor, and records the sending and receiving times of the trigger information, as well as the receiving and height data.

[0064] Step 102: Generate a time-altitude matrix using various altitude data and data measurement time.

[0065] It should be noted that the data measurement time includes the time for sending the measurement and the time for receiving the measurement.

[0066] In a specific embodiment, a time-height matrix is ​​generated by using various height data, the corresponding transmission and reception times of the height data.

[0067] Step 103: Calculate the absolute position coordinate matrix of each partial discharge UHF sensor based on the time-height matrix.

[0068] In a specific embodiment, the relative positions between each partial discharge UHF sensor are calculated using the height data, measurement transmission time, measurement reception time, and speed of light in the time-height matrix. Then, the coordinate axis information of one of the partial discharge UHF sensors is preset, thereby calculating the coordinate axis information of adjacent partial discharge UHF sensors. The relative positions between each device are iteratively calculated, and the coordinate axis matrix corresponding to the relative positions of each partial discharge UHF sensor is constructed, thereby determining the absolute position coordinate matrix of a certain partial discharge UHF sensor.

[0069] Step 104: In response to the input GIS device size data, construct a GIS device size matrix, wherein the GIS device size matrix includes the absolute position information of the GIS device insulation disk.

[0070] It should be noted that the partial discharge UHF sensor is installed inside the insulating panel of the GIS equipment, therefore the absolute position information of the insulating panel of the GIS equipment is consistent with the absolute position information of the corresponding partial discharge UHF sensor.

[0071] In a specific embodiment, GIS device size data can be obtained from the host device 13 to construct a GIS device size matrix, which includes the absolute position information of the GIS device insulation disk.

[0072] Step 105: Compare the absolute position coordinate matrix of each partial discharge UHF sensor with the size matrix of each GIS device to generate a partial discharge UHF sensor layout map.

[0073] In a specific embodiment, the x-axis, y-axis, and z-axis coordinates corresponding to the absolute position coordinate matrix of each partial discharge UHF sensor are compared with the x-axis, y-axis, and z-axis coordinates corresponding to the absolute position information of the GIS equipment insulating disk in each GIS equipment size matrix. If the coordinate information matches, the position of the GIS equipment insulating disk can be determined based on the installation position of the partial discharge UHF sensor. By connecting the GIS equipment insulating disk, the type of GIS equipment can be determined, and a GIS equipment wiring diagram can be formed, thereby automatically generating a partial discharge UHF sensor layout diagram. If the coordinate information does not match, it means that the installation position of the partial discharge UHF sensor is not on the GIS equipment insulating disk. A new GIS equipment size matrix [G] needs to be selected, and the absolute position matrix [Z] of the device and the GIS equipment size matrix [G] are compared again until the compared coordinate information matches.

[0074] This invention measures the height data of each partial discharge (PD) UHF sensor in response to received trigger information; generates a time-height matrix using the height data and measurement time; calculates the absolute position coordinate matrix of each PD UHF sensor based on the time-height matrix; constructs a GIS device size matrix in response to input GIS device size data, where the GIS device size matrix includes the absolute position information of the GIS device's insulating disc; and compares the absolute position coordinate matrix of each PD UHF sensor with the GIS device size matrix to generate a PD UHF sensor layout map. This solves the current technical problem that in inspection applications requiring sensor position parameters, sensor position parameters are obtained manually and then input into monitoring or detection devices for analysis and calculation; and when constructing a sensor layout map using sensor position parameters, manual drawing is required. Therefore, the sensor spatial position information has significant errors and low accuracy.

[0075] This invention automatically calculates the absolute position of the sensors installed in the online monitoring device and the relative position of the sensors installed for live testing, providing important parameters for the investigation and location of partial discharge anomalies. It completely avoids the manual measurement of sensor distances during the investigation of partial discharge anomalies in GIS equipment, effectively reducing measurement errors and improving work efficiency and the reliability of results.

[0105] It should be noted that the measurement transmission time is the time when the information is transmitted, and the measurement reception time is the time when the information is received. The various partial discharge UHF sensors correspond to devices A, B, and C, respectively.

[0106] In a specific embodiment, the formula for calculating the relative position between device A and device B is as follows:

[0107] D AB =c*(T) BA -T A )

[0108] Where c is the speed of light, T BA T is the time when device B receives information from device A. A The time when device A sends the information.

[0109] By providing a preset value for the coordinates of the outermost device, typically set to (0, 0, z)... A Then, by using time multiplication and height data, the coordinate information of adjacent devices is calculated, and the relative position between each device is calculated iteratively. The coordinate axis matrix corresponding to the relative position of each partial discharge UHF sensor is constructed, thereby determining the absolute position coordinate matrix [Z] of a certain partial discharge UHF sensor.

[0110] Optionally, step S13 includes the following steps S131-S132:

[0111] S131. Set the x-axis coordinate and y-axis coordinate of the first partial-amplifier UHF sensor to preset values ​​for x-axis coordinate and y-axis coordinate, respectively.

[0112] S132. Using time multiplication and the height data corresponding to the first, second, and third partial discharge UHF sensors, calculate the x-axis and y-axis coordinates of the second and third partial discharge UHF sensors, and determine the coordinate axis information corresponding to the relative positions of each partial discharge UHF sensor.

[0113] It should be noted that the first UHF partial discharge sensor corresponds to device A, the second UHF partial discharge sensor corresponds to device B, and the third UHF partial discharge sensor corresponds to device C.

[0114] In a specific embodiment, device A is set to preset x-axis coordinates and preset y-axis coordinates, both of which are 0. Therefore, the coordinate information of device A is (0, 0, z). A ), x corresponding to computing device B B and y B The x corresponding to computing device C C and y C This allows for iterative calculation of the coordinate axis information corresponding to the relative positions of each partial discharge UHF sensor or device. The calculation formula is as follows:

[0115]

[0116] Among them, D AB Let D be the distance between device A and device B. BC Let D be the distance between device B and device C. AC Let c be the distance between device A and device B, and c be the speed of light.

[0117] Step 205: Response to the input GIS device size data, construct a GIS device size matrix, wherein the GIS device size matrix includes the absolute position information of the GIS device insulation disk.

[0118] Optionally, this method includes the following step S21:

[0119] S21. Place the partial discharge UHF sensor inside the insulating tray of the GIS equipment.

[0120] In a specific embodiment, the location marking device is mounted on the partial discharge UHF sensor, which is itself mounted inside the insulating tray of the GIS equipment. A GIS device has multiple insulating trays; by connecting these trays, a partial discharge UHF sensor distribution map can be formed.

[0121] Step 206: Compare the absolute position coordinate matrix of each partial discharge UHF sensor with the size matrix of each GIS device to generate a partial discharge UHF sensor layout map.

[0122] Optionally, step 206 includes the following steps S31-S33:

[0123] S31. Compare the coordinate information corresponding to the absolute position coordinate matrix of each partial discharge UHF sensor with the coordinate information corresponding to the absolute position information of the GIS equipment insulating disk in the GIS equipment size matrix.

[0124] S32. If the coordinate information is consistent, determine the GIS equipment type based on the GIS equipment size matrix, and generate the GIS equipment wiring diagram and the partial discharge UHF sensor layout diagram.

[0125] S33. If the coordinate information is inconsistent, select the remaining GIS equipment size matrix as the new GIS equipment size matrix, and jump to execute the step of comparing the coordinate information corresponding to the absolute position coordinate matrix of each partial discharge UHF sensor with the coordinate information corresponding to the absolute position information of the GIS equipment insulating disk in the GIS equipment size matrix.

[0126] In a specific embodiment, such as Figure 7As shown, using the working network constructed by the host device 13 and the network module 2, the GIS equipment size data is transmitted to the network module 2 through the receiving antenna 11, and then transmitted to the storage module 4 through the data output terminal 2-4 and the data input terminal 4-3. A GIS equipment size matrix [G] is constructed in the storage module 4. The GIS equipment size matrix [G] records the absolute position information [X] of the GIS equipment insulating disk. G ,Y G Z G ], X G Y G Z G These correspond to the x-axis, y-axis, and z-axis coordinates of components in GIS equipment where partial discharge UHF sensors can be installed.

[0127] By comparing the absolute position matrix [Z] of the comparison device with the GIS equipment size matrix [G], if the coordinate information matches, the position of the GIS equipment insulation panel can be determined based on the installation location of the partial discharge UHF sensor. Connecting the GIS equipment insulation panel reveals the type of GIS equipment and generates a GIS equipment wiring diagram, thereby automatically generating a partial discharge UHF sensor layout map. If the coordinate information does not match, it indicates that the installation location of the partial discharge UHF sensor is not on the GIS equipment insulation panel. A new GIS equipment size matrix [G] needs to be selected, and the absolute position matrix [Z] of the comparison device and the GIS equipment size matrix [G] need to be compared again until the compared coordinate information matches.

[0128] Optionally, this method further includes the following steps S41-S44:

[0129] S41. In response to the received update trigger information, measure the updated altitude data of the partial discharge UHF sensor;

[0130] S42. Compare the altitude data and data measurement time with the updated altitude data and updated data measurement time, respectively;

[0131] S43. If the data is consistent, then the partial discharge UHF sensor is confirmed to be in its original position.

[0132] S44. If the data is inconsistent, it is determined that the partial discharge UHF sensor has been displaced, and a displacement alarm message is generated.

[0133] In a specific embodiment, such as Figure 8 As shown, the clock module 3 periodically sends a trigger signal to the laser positioning trigger terminal 5-3 of the laser positioning module 5 through the time recording trigger terminal 3-4, triggering the laser positioning module 5 to measure the height position of the device.

[0134] After the measurement is completed, the laser positioning module 5 sends a signal to the clock recording trigger terminal 3-3 of the clock module 3 through the laser ranging trigger terminal 5-4, triggering the clock module 3 to record time information. At the same time, the laser positioning module 5 transmits the device height data to the storage module 4 through the data input terminal 4-3 through the laser positioning data output terminal 5-5. After the clock module 3 finishes recording the time data, it transmits the updated measurement time data to the storage module 4 through the time data output terminal 3-5 and the data input terminal 4-3.

[0135] The storage module 4 generates information consisting of the updated altitude data and the updated data measurement time data of the partial discharge ultra-high frequency sensor. The data is transmitted to the network module 2 via the data output terminal 4-4 and the data input terminal 2-3. The network module then transmits the information to the host device 13 via the transmitting antenna 11.

[0136] The host device 13 generates a sensor displacement alarm when there are significant changes in the data, based on the updated data measurement time and the updated height data compared with the previous height data and data measurement time.

[0137] This invention measures the height data of each partial discharge (PD) UHF sensor in response to received trigger information; generates a time-height matrix using the height data and measurement time; calculates the absolute position coordinate matrix of each PD UHF sensor based on the time-height matrix; constructs a GIS device size matrix in response to input GIS device size data, where the GIS device size matrix includes the absolute position information of the GIS device's insulating disc; and compares the absolute position coordinate matrix of each PD UHF sensor with the GIS device size matrix to generate a PD UHF sensor layout map. This solves the current technical problem that in inspection applications requiring sensor position parameters, sensor position parameters are obtained manually and then input into monitoring or detection devices for analysis and calculation; and when constructing a sensor layout map using sensor position parameters, manual drawing is required. Therefore, the sensor spatial position information has significant errors and low accuracy.

[0138] This invention automatically calculates the absolute position of the sensors installed in the online monitoring device and the relative position of the sensors installed for live testing, providing important parameters for the investigation and location of partial discharge anomalies. It completely avoids the manual measurement of sensor distances during the investigation of partial discharge anomalies in GIS equipment, effectively reducing measurement errors and improving work efficiency and the reliability of results.
