Description

Technical Field

[0001] The present invention relates to the technical field of substation management and control, and in particular to a substation secondary safety measure management and control method, device, system and storage medium. Background Art

[0002] At present, the secondary safety measures control method of substations is as follows: managers at all levels conduct advance checks on key information such as work tickets and secondary safety measures through online operation risk control work groups in accordance with the requirements of operation risks and supervision methods. After the on-site operators have executed the secondary measures, they upload the secondary measures and photos of the on-site safety measures to the operation risk control work group. The professional specialists of the substation management office will review the safety measures and issue professional approval after confirming that they are correct and complete. After the work is completed, the on-site operators upload the secondary measures and photos of the on-site safety measures recovery to the operation risk control work group, which will be reviewed and confirmed by the professional specialists of the substation management office. The professional specialists of the system department will conduct random inspections of relevant secondary safety measures information.

[0003] The existing secondary safety measures control methods for substations have the following main problems: 1. The effectiveness of safety measures review depends on the experience and sense of responsibility of managers, and the verification efficiency is low; 2. There is a lack of control over safety measures during the operation; 3. With the popularization of smart stations, on-site secondary safety measures are gradually electronic.

[0062] Embodiment 1

[0063] Figure 1 It is a flowchart of a substation secondary safety measure control method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of safety control of substation secondary operations. This method can be executed by a substation secondary safety measure control device, and the substation secondary safety measure control device can be implemented in the form of hardware and / or software. The substation secondary safety measure control device can be configured in a substation. As Figure 1 shown, the substation secondary safety measure control method includes:

[0064] S100. Establish a secondary safety measure reference library, where the secondary safety measure reference library includes a protection device status reference, a secondary measure list library reference, a secondary safety measure execution reference, and a secondary safety measure restoration reference.

[0065] Among them, during the control of secondary safety measures, the components involved usually include pressure plates, terminals, and air switches. Therefore, the pressure plate reference can be stored according to intervals, protection devices, operation types, operation stages (after implementing safety measures, after restoring safety measures) and the position (such as the first row and the first column) of the pressure plate withdrawal situation. The pressure plate at each position can also be named; the terminal safety measure reference can be stored according to intervals, protection devices, operation types, and operation stages (such as sealing: 1KD9; opening and sealing: 1UD1, etc.); the air switch reference can be stored according to intervals, protection devices, operation types, and operation stages at the position (such as the first one), and the air switch at each position can be named. Each reference state can be modified. The secondary safety measure implementation reference refers to the state that each component should be in when implementing secondary safety measures. When the components at this time involve pressure plates, terminals, and air switches, it is the reference value of the pressure plates, terminals, and air switches after the operation stage of implementing safety measures. The secondary safety measure restoration reference refers to the state that each component should be in after the implementation of secondary safety measures. When the components at this time involve pressure plates, terminals, and air switches, it is the reference value of the pressure plates, terminals, and air switches after the operation stage of restoring safety measures.

[0066] The protection device status reference refers to the reference value of each component when the protection device is in different states. For example, the protection device status reference includes the protection device maintenance state reference, the protection device operation state reference, and the protection device isolation state reference. When the protection device is in different states, according to the different types of substations, there will be corresponding reference values for soft pressure plates, hard pressure plates, and switch quantities related to the protection device.

[0067] The secondary measure list records the specific content of secondary safety measures, and the operating personnel can implement secondary safety measures according to the secondary measure list. For example, the secondary measure list records the specific operations that should be carried out on pressure plates, terminals, and air switches at different operation stages, that is, which terminals need to be sealed, which pressure plates need to be withdrawn or inserted, etc. Since the corresponding secondary measure lists are different when the intervals, protection devices, and operation types are different, the secondary measure list library reference can store the secondary measure list reference in text according to intervals, protection devices, and operation types to form the secondary measure list library reference.

[0068] S110. Obtain the protection device status information.

[0069] Among them, the protection device status information refers to the actual state that the protection device is currently in. For an intelligent substation, the protection device usually includes soft pressure plates, hard pressure plates, and switch quantities. At this time, it refers to the current state values of the soft pressure plates, hard pressure plates, and switch quantities. For a conventional substation, the protection device usually includes hard pressure plates. At this time, it is the state of the hard pressure plate, that is, the withdrawal or insertion situation.

[0070] S120. Determine whether the substation protection device is in the maintenance state based on the protection device status information and the protection device status reference.

[0071] Among them, before implementing secondary safety measures, it is usually necessary to first put the protection device into the maintenance state to prevent false alarms during the implementation of secondary safety measures. The protection device state reference refers to the reference values of each component when the protection device is in different states. Therefore, based on the protection device state information and the protection device state reference, it is possible to determine whether the substation protection device is in the maintenance state.

[0072] If the substation protection device is in the maintenance state, step S140 is executed. If the substation protection device is not in the maintenance state, it indicates an error at this time. The on-site personnel can check and then execute step S110 again, and execute the secondary safety measure control process again.

[0073] S130. Obtain the content information of the secondary measure list.

[0074] Among them, the content information of the secondary measure list refers to the specific content of the secondary measure list confirmed on-site. There are various ways to obtain it. It can be manually input on-site, or photographed and input, and then the content information of the secondary measure list is obtained through image recognition.

[0075] S140. Determine whether the secondary measure list is correct based on the content information of the secondary measure list and the secondary measure list library reference.

[0076] Among them, the secondary measure list library reference includes the secondary measure list references in different situations. The content information of the secondary measure list refers to the specific content of the secondary measure list confirmed on-site. Therefore, based on the content information of the secondary measure list and the secondary measure list library reference, it is possible to determine whether the on-site secondary measure list is correct.

[0077] If the secondary measure list is correct, step S140 is executed. If the secondary measure list is incorrect, it indicates that there may be an error in uploading. The on-site personnel can re-check the secondary measure list and re-upload it, and then execute step S130 again at this time.

[0078] S150. Obtain the secondary safety measure execution information.

[0079] Among them, the secondary safety measure execution information refers to the actual execution situation of the on-site secondary safety measures.

[0080] S160. Determine whether the secondary safety measures are executed correctly based on the secondary safety measure execution information and the secondary safety measure execution reference.

[0081] Among them, the secondary safety measure execution reference refers to the state that each component should be in when implementing secondary safety measures. The secondary safety measure execution information refers to the actual execution situation of the on-site secondary safety measures. Therefore, based on the secondary safety measure execution information and the secondary safety measure execution reference, it is possible to determine whether the secondary safety measures are executed correctly.

[0082] If the secondary safety measures are correctly implemented, step S140 is executed. If the secondary safety measures are incorrectly implemented, it indicates that the on-site personnel have made mistakes. They can re-check the secondary safety measures on-site and then re-confirm. At this time, step S150 is executed again.

[0083] S170. Obtain the secondary safety measure restoration information.

[0084] Among them, after the secondary safety measures are implemented, restoration is usually required. The secondary safety measure restoration information refers to the actual restoration situation of the on-site secondary safety measures.

[0085] S180. Determine whether the secondary safety measures are correctly restored based on the secondary safety measure restoration information and the secondary safety measure restoration benchmark.

[0086] If the secondary safety measures are correctly restored, the secondary safety measure control process ends.

[0087] Among them, the secondary safety measure restoration benchmark refers to the state that each component should be in after the secondary safety measures are implemented. The secondary safety measure restoration information refers to the actual restoration situation of the on-site secondary safety measures. Therefore, it is convenient to determine whether the secondary safety measures are correctly restored based on the secondary safety measure restoration information and the secondary safety measure restoration benchmark. When the secondary safety measures are correctly restored, it indicates that the process of the secondary safety measures has ended, and the secondary safety measure control process ends. When the secondary safety measures are not correctly restored, it indicates that there is an error in the restoration. At this time, the on-site personnel re-check the restoration situation of the secondary safety measures, and then execute S170 again.

[0088] In the above solution, by establishing a secondary safety measure benchmark library, the secondary safety measure benchmark library includes a protection device status benchmark, a secondary measure sheet library benchmark, a secondary safety measure implementation benchmark, and a secondary safety measure restoration benchmark. Then, according to the actual situation on-site, it is sequentially determined whether the substation protection device is in the maintenance state, whether the secondary measure sheet is correct, whether the secondary safety measures are correctly implemented, and whether the secondary safety measures are correctly restored. Therefore, it can automatically control the entire process of the secondary safety measures without manual review. Therefore, the review efficiency is high, it can control the whole process, and the reliability is strong. It solves the problems of low review efficiency, lack of control over safety measures, and poor reliability in the existing substation secondary safety measure control methods.

[0089] Embodiment 2

[0090] Figure 2It is a flowchart of a secondary safety measure control method provided in the second embodiment of the present invention. This embodiment improves the relationship with the above embodiment. Optionally, the protection device status information includes soft pressure plate status information, hard pressure plate status information, and digital input status information, and the protection device status reference includes the protection device maintenance status reference; before obtaining the protection device status information, it further includes: determining whether the substation is an intelligent substation; based on this, as Figure 2 shown, the method includes:

[0091] S200. Establish a secondary safety measure reference library, where the secondary safety measure reference library includes a protection device status reference, a secondary measure list library reference, a secondary safety measure execution reference, and a secondary safety measure restoration reference.

[0092] S210. Determine whether the substation is an intelligent substation.

[0093] Among them, for an intelligent substation, the protection device usually includes soft pressure plates, hard pressure plates, and digital inputs. At this time, it refers to the current state values of the soft pressure plates, hard pressure plates, and digital inputs. For a conventional substation, the protection device usually includes hard pressure plates. At this time, it is the state of the hard pressure plates, that is, the switching status. Therefore, for different types of substations, the protection devices are different, so it is necessary to determine whether the substation is an intelligent substation.

[0094] If the substation is an intelligent substation, execute step S2211. When the substation is not an intelligent substation, that is, a conventional substation, execute step S2221 at this time.

[0095] S2211. Obtain the soft pressure plate status information, hard pressure plate status information, and digital input status information.

[0096] Among them, the soft pressure plate status information, hard pressure plate status information, and digital input status information respectively refer to the current soft pressure plate, hard pressure plate, and digital input status values of the protection device in the intelligent substation, and can be obtained through communication.

[0097] S2212. Compare the soft pressure plate status information, the hard pressure plate status information, and the digital input status information with the protection device maintenance status reference to obtain a first comparison result.

[0098] Among them, the protection device maintenance status reference refers to the reference values of the components involved in the protection device maintenance when the protection device is in the maintenance state. At this time, it refers to the reference values of the soft pressure plates, hard pressure plates, and digital inputs. Therefore, only by comparing the soft pressure plate status information, the hard pressure plate status information, and the digital input status information with the protection device maintenance status reference, the first comparison result obtained can reflect the comparison situation between the two, and then determine whether the protection device is in the maintenance state.

[0099] S2213. Confirm whether the comparison is consistent based on the first comparison result.

[0100] If the first comparison result is consistent, determine that the substation protection device is in the maintenance state and execute step S240. If the first comparison result is inconsistent, the substation protection device is not in the maintenance state, indicating an error at this time. The on-site personnel can check and then execute step S2211 again to execute the secondary safety measure control process again. Optionally, when the first comparison result is inconsistent, an alarm reminder message can be sent. The alarm reminder message refers to the information that alarms and reminds the operators, which can be a prompt box, sound, light, or vibration, etc. In this way, it is convenient for the on-site operators to know the inconsistent comparison situation in a timely manner.

[0101] S2221. Obtain the image information of the protection device's hard pressure plate, and determine the hard pressure plate status information based on the protection device's pressure plate image information.

[0102] Among them, the protection device's hard pressure plate image information refers to the image information including the hard pressure plate, and the hard pressure plate status information refers to the on / off status of the hard pressure plate. There are various ways to determine the hard pressure plate status information based on the protection device's pressure plate image information. For example, if the protection device's hard pressure plate image information is a photo of the hard pressure plate, the on / off status of the hard pressure plate in the photo can be identified through the yolov5 algorithm to obtain the hard pressure plate status information.

[0103] S2222. Compare the hard pressure plate status information with the maintenance state reference of the protection device to obtain a second comparison result.

[0104] Among them, the maintenance state reference of the protection device refers to the reference value of the components involved in the maintenance of the protection device when the protection device is in the maintenance state. At this time, it refers to the reference value of the on / off status of the hard pressure plate. Therefore, only by comparing the hard pressure plate status information with the maintenance state reference of the protection device, the second comparison result obtained can reflect the comparison situation between the two, and then determine whether the protection device is in the maintenance state.

[0105] S2223. Confirm whether the comparison is consistent based on the second comparison result.

[0106] If the second comparison result is consistent, determine that the substation protection device is in the maintenance state and execute step S240. If the second comparison result is inconsistent, the substation protection device is not in the maintenance state, indicating an error at this time. The on-site personnel can check and then execute step S2221 again to execute the secondary safety measure control process again. Optionally, when the second comparison result is inconsistent, an alarm reminder message is sent. The alarm reminder message refers to the information that alarms and reminds the operators, which can be a prompt box, sound, light, or vibration, etc. In this way, it is convenient for the on-site operators to know the inconsistent comparison situation in a timely manner.

[0107] S230. Obtain the content information of the secondary measure sheet.

[0108] S240. Determine whether the secondary measure sheet is correct based on the content information of the secondary measure sheet and the benchmark of the secondary measure sheet library.

[0109] If the secondary measure sheet is correct, execute step S240. If the secondary measure sheet is incorrect, it indicates that there may be an error in uploading. The site can re-check the secondary measure sheet and upload it again. At this time, execute step S230 again.

[0110] S250. Obtain the execution information of the secondary safety measures.

[0111] S260. Determine whether the secondary safety measures are executed correctly based on the execution information of the secondary safety measures and the execution benchmark of the secondary safety measures.

[0112] If the secondary safety measures are executed correctly, execute step S240. If the secondary safety measures are executed incorrectly, it indicates that there is an error in the execution by on-site personnel. The site can re-check the secondary safety measures and re-confirm. At this time, execute step S250 again.

[0113] S270. Obtain the recovery information of the secondary safety measures.

[0114] S280. Determine whether the secondary safety measures are recovered correctly based on the recovery information of the secondary safety measures and the recovery benchmark of the secondary safety measures.

[0115] If the secondary safety measures are recovered correctly, end the control process of the secondary safety measures. When the secondary safety measures are not recovered correctly, it indicates that there is an error in the recovery. At this time, the site re-checks the recovery situation of the secondary safety measures, and then executes S270 again.

[0116] The above solution can select and determine the specific method for whether the protection device is in the maintenance state according to the type of substation, so as to more accurately determine whether the protection device is in the maintenance state.

[0117] Optionally, the secondary safety measure control method for the substation further includes establishing a first deep learning model, identifying the content of the protection device pressure plate image information through the first deep learning model to determine the hard pressure plate state information. When the second comparison result is inconsistent, manually confirm whether it is an identification error. If so, collect the situation of the identification error and train the first deep learning model.

[0118] In an optional embodiment of the present invention, the obtaining the content information of the secondary measure sheet and determining whether the secondary measure sheet is correct based on the content information of the secondary measure sheet and the benchmark of the secondary measure sheet library includes:

[0119] Obtain the image information of the secondary measure sheet.

[0120] Determine the content information of the secondary measure list based on the secondary measure list image information.

[0121] Compare the content information of the secondary measure list with the benchmark of the secondary measure list library to obtain a third comparison result.

[0122] Based on the third comparison result, confirm whether the comparison is consistent.

[0123] When the third comparison result is consistent, determine that the secondary measure list is correct.

[0124] When the third comparison result is inconsistent, determine that the secondary measure list is incorrect, send an alarm reminder message, and execute the step of obtaining the secondary measure list image information again.

[0125] Among them, the secondary measure list image information refers to the image including the secondary measure list uploaded on site, such as a photo of the secondary measure list. By identifying the secondary measure list image information through image recognition, the content information of the secondary measure list can be determined. In a specific embodiment, the CNN+RNN+CTC algorithm is selected to identify the content of the secondary measure list to obtain the content information of the secondary measure list.

[0126] The benchmark of the secondary measure list library includes the secondary measure list benchmarks in different situations. Therefore, comparing the content information of the secondary measure list with the benchmark of the secondary measure list library, the obtained third comparison result can reflect whether the secondary measure list on site is correct. When the third comparison result is consistent, determine that the secondary measure list is correct. When the third comparison result is inconsistent, determine that the secondary measure list is incorrect and send an alarm reminder message, which is convenient for on-site operators to know the error situation of the secondary measure list in time, with high efficiency.

[0127] Optionally, the secondary safety measure control method for the substation further includes establishing a second deep learning model, identifying the secondary measure list image information through the second deep learning model to obtain the content information of the secondary measure list. When the third comparison result is inconsistent, manually confirm whether it is an identification error. If so, collect the situation of the identification error and train the second deep learning model.

[0128] In an optional embodiment of the present invention, the obtaining of the secondary safety measure execution information and determining whether the secondary safety measure is executed correctly based on the secondary safety measure execution information and the secondary safety measure execution benchmark includes:

[0129] Acquire secondary safety measure image information, and determine secondary safety measure execution information based on the secondary safety measure image information, compare the secondary safety measure execution information with the secondary safety measure execution benchmark to obtain a fourth comparison result, and confirm whether the comparison is consistent based on the fourth comparison result, if the fourth comparison result is consistent, determine that the secondary safety measure is executed correctly, if the fourth comparison result is inconsistent, determine that the secondary safety measure is executed incorrectly; wherein, the secondary safety measure image information includes hard pressure plate image information, terminal image information and circuit breaker image information, and the secondary safety measure execution benchmark includes hard pressure plate secondary safety measure state benchmark, terminal secondary safety measure state benchmark and circuit breaker secondary safety measure state benchmark.

[0130] Among them, the secondary safety measure image information refers to the image of the component that performs the secondary safety measure. For example, when performing the secondary safety measure, the hard pressure plate, the terminal and the circuit breaker will all move, so the secondary safety measure image information includes the hard pressure plate image information, the terminal image information and the circuit breaker image information. The secondary safety measure execution information refers to the information reflecting the execution status of the secondary safety measure, such as whether the hard pressure plate is put into use. On the basis of knowing the secondary safety measure image information, the secondary safety measure execution information can be obtained through the image recognition method. In a specific embodiment, the secondary safety measure image information includes photos of the hard pressure plate, the terminal block and the air switch. The execution status of the hard pressure plate and the circuit breaker in the photo is identified by the yolov5 algorithm, and the execution status of the terminal safety measure is identified by the Mask-RCNN+CNN+RNN+CTC algorithm, so as to obtain the secondary safety measure execution information.

[0131] The secondary safety measure execution benchmark refers to the state that each component should be in when executing the secondary safety measure. Since the hard pressure plate, terminal and circuit breaker will all move when the secondary safety measure is executed, the secondary safety measure execution benchmark includes the hard pressure plate secondary safety measure state benchmark, the terminal secondary safety measure state benchmark and the circuit breaker secondary safety measure state benchmark. The fourth comparison result obtained by comparing the secondary safety measure execution information with the secondary safety measure execution benchmark can reflect whether the secondary measure is executed correctly. If the fourth comparison result is consistent, it is determined that the secondary safety measure is executed correctly. If the fourth comparison result is inconsistent, it is determined that the secondary safety measure is executed incorrectly. An alarm reminder message is issued when the secondary safety measure is executed incorrectly. After rechecking the secondary safety measures on site, the secondary safety measure image information is uploaded.

[0132] Through the above method, it is possible to easily determine whether the secondary security measure is executed correctly.

[0133] Optionally, the substation secondary safety measures management and control method also includes establishing a third deep learning model, identifying the secondary safety measures image information through the third deep learning model to obtain secondary safety measures execution information, and when the fourth comparison result is inconsistent, manually confirming whether it is a recognition error, and if so, collecting the recognition error situations and training the third deep learning model.

[0134] In an optional embodiment of the present invention, the secondary safety measure recovery information includes hard pressure plate image information, terminal image information, circuit breaker image information, protection device constant value information, soft pressure plate status information, hard pressure plate status information and switch quantity status information, and the secondary safety measure recovery benchmark includes hard pressure plate recovery benchmark, terminal recovery benchmark, circuit breaker recovery benchmark, protection device constant value recovery benchmark, soft pressure plate recovery benchmark and switch quantity recovery benchmark.

[0135] The obtaining of the secondary security measure recovery information, and determining whether the secondary security measure is correctly recovered based on the secondary security measure recovery information and the secondary security measure recovery benchmark, includes:

[0136] Obtain hard pressure plate image information, terminal image information, and circuit breaker image information, determine hard pressure plate recovery information, terminal recovery information, and circuit breaker recovery information based on the hard pressure plate image information, terminal image information, and circuit breaker image information, compare the hard pressure plate recovery information, terminal recovery information, and circuit breaker recovery information with the hard pressure plate recovery benchmark, terminal recovery benchmark, and circuit breaker recovery benchmark one by one to obtain a fifth comparison result, and confirm whether the comparisons are consistent based on the fifth comparison result.

[0137] If it is confirmed that the comparisons are consistent, the protection device setting information and the protection device setting recovery benchmark are compared to obtain a sixth comparison result, and whether the comparisons are consistent is confirmed based on the sixth comparison result.

[0138] If the sixth comparison result of the protection device setting information and the protection device setting recovery benchmark is consistent, it is determined whether it is a smart substation.

[0139] If it is a smart substation, the soft pressure plate status information and the switch quantity status information are compared with the soft pressure plate recovery benchmark and the switch quantity recovery benchmark one by one to obtain the seventh comparison result, and confirm whether the seventh comparison results are consistent. If the seventh comparison results are consistent, it is confirmed that the secondary safety measure has been restored correctly.

[0140] If it is not a smart substation, make sure that the secondary safety measures are restored correctly.

[0141] Among them, since the hard pressure plate, terminals and circuit breakers will all move when the secondary installation is executed, the hard pressure plate, terminals and circuit breakers must also be restored to a specific state after the secondary installation is completed. When the image information of the hard pressure plate, the image information of the terminal and the circuit breaker is known, the hard pressure plate recovery information, the terminal recovery information and the circuit breaker recovery information can be determined through the image processing algorithm. In a specific embodiment, the yolov5 algorithm is used to identify the recovery status of the hard pressure plate and circuit breaker in the photo to obtain the hard pressure plate recovery information and the circuit breaker recovery information, and the Mask-RCNN+CNN+RNN+CTC algorithm is used to identify the terminal installation recovery status to obtain the terminal recovery status information.

[0142] The hard pressure plate recovery benchmark, terminal recovery benchmark, and circuit breaker recovery benchmark respectively reflect the benchmark values ​​of the recovery of the hard pressure plate, terminal, and circuit breaker. Therefore, the fifth comparison result obtained by comparing the hard pressure plate recovery information, terminal recovery information, and circuit breaker recovery information with the hard pressure plate recovery benchmark, terminal recovery benchmark, and circuit breaker recovery benchmark one by one can reflect the recovery status of the hard pressure plate, terminal, and circuit breaker. If the comparison is confirmed to be consistent, it means that the hard pressure plate, terminal, and circuit breaker have all recovered. At this time, the next step is executed to determine whether the set value of the protection device has been restored. If it is confirmed that there is an inconsistency in the comparison, it means that the hard pressure plate, terminal, and circuit breaker have not been restored. After re-checking on site, the hard pressure plate image information, terminal image information, and circuit breaker image information are uploaded again.

[0143] Among them, the protection device setting recovery benchmark refers to the benchmark value of the setting of the protection device after the secondary protection measure is restored, and the protection device setting information refers to the current actual setting of the protection device. The sixth comparison result is obtained by comparing the protection device setting information with the protection device setting recovery benchmark. The sixth comparison result can determine whether the setting of the protection device is restored to the benchmark. When the protection device setting information and the protection device setting recovery benchmark are consistent with the sixth comparison result, it means that the setting of the protection device has been restored to the benchmark at this time, and the next step is executed to determine whether it is a smart substation. If the protection device setting information and the protection device setting recovery benchmark are inconsistent, it means that the setting of the protection device has not been restored to the benchmark at this time, indicating that there is an error. At this time, an alarm reminder message can be issued, and the on-site re-check is re-determined whether the setting of the protection device is restored to the benchmark.

[0144] Due to the difference between smart substations and conventional substations, in addition to hard pressure plates, smart substations also have soft pressure plates and switch quantities. Therefore, when the substation is not a smart substation, it means that all have been restored correctly and the process ends. When the substation is a smart substation, the soft pressure plate status information and switch quantity status information need to be compared with the soft pressure plate recovery benchmark and the switch quantity recovery benchmark one by one to obtain the seventh comparison result, and confirm whether the seventh comparison result is consistent. If the seventh comparison result is consistent, it is confirmed that the secondary safety measures have been restored correctly.

[0145] Optionally, the substation secondary safety measures management method also includes establishing a fourth deep learning model, and identifying the hard pressure plate image information, terminal image information, and circuit breaker image information through the fourth deep learning model to obtain hard pressure plate recovery information, terminal recovery information, and circuit breaker recovery information. When the fifth comparison result is inconsistent, manually confirm whether it is an identification error. If so, collect the identification errors and train the fourth deep learning model.

[0146] In an optional embodiment of the present invention, the secondary safety measure reference library includes key reference items; before obtaining the hard pressing plate image information, the terminal image information, and the circuit breaker image information, the following is further included:

[0147] Determine whether it is a smart substation.

[0148] If it is a smart substation, start the management and control function, wherein the management and control function includes obtaining benchmark change information, issuing an alarm message when the benchmark change information includes a change in a key benchmark item, comparing the status information of the protection device corresponding to the benchmark change information with the isolation state benchmark value, and if they are consistent, changing the key benchmark item corresponding to the benchmark change information in the secondary safety measure benchmark library based on the benchmark change information.

[0149] If it is not a smart substation, execute the steps of obtaining the hard pressure plate image information, terminal image information, and circuit breaker image information.

[0150] Among them, the key benchmark items refer to the operation items that may cause the protection device to malfunction and cause power grid accidents when operating the protection device. Specifically, the key benchmark items may include failure soft pressure plates, joint trip soft pressure plates, maintenance hard pressure plates, etc. The benchmark change information reflects the changes in the benchmarks in the secondary safety measures benchmark library. The isolated state refers to the state in which the protection device is isolated from other associated devices. When it is necessary to change the key benchmark items, in order to avoid the protection device from malfunctioning and causing power grid accidents, the protection device must be placed in an isolated state first. Therefore, the state information of the protection device corresponding to the benchmark change information is compared with the isolated state benchmark value. When the two are consistent, it means that the protection device is in an isolated state. At this time, the key benchmark items corresponding to the benchmark change information in the secondary safety measures benchmark library can be changed according to the benchmark change information. Through the above method, it is possible to effectively avoid the protection device from malfunctioning and causing power grid accidents during the management and control process, and it is also possible to modify and change the benchmarks in the secondary safety measures benchmark library in a timely manner.
