Description

Technical Field

[0001] The present invention belongs to the technical field of anti-mistaken locking, and in particular relates to a method and device, equipment and storage medium for controlling the anti-mistaken locking of a trolley-type switch cabinet. Background Art

[0002] The anti-misoperation locking device is a mechanical device installed on high-voltage electrical equipment to prevent misoperation by utilizing its own established program locking function. It can realize five protection functions, including preventing mis-opening and mis-closing of circuit breakers; preventing pulling and closing of disconnectors under load; preventing closing of grounding wires (switches) under power (hanging); preventing closing of circuit breakers (disconnectors) with grounding wires (switches) under power; and preventing accidental entry into live intervals.

[0003] Before the electrical operation of the power system, the anti-error locking device needs to be locked, and after the electrical operation, the anti-error locking device needs to be locked. It is a positive measure to prevent the operator's misoperation accidents. The realization of the anti-misoperation function has become one of the important measures for power safety production.

[0004] At present, most of the domestic high-voltage switch cabinets use trolley-type switch cabinets. In order to make the trolley-type switch cabinet easy to operate, the trolley is equipped with a hand-cranking mechanism (such as a manual crank or a rocker, etc.), which allows the trolley to flexibly enter and exit the switch cabinet. Most switch cabinets are equipped with an anti-mistake locking device on the trolley hand-cranking mechanism, which has a certain "five-prevention" function.

[0005] Usually, an unlocking key is used to unlock the anti-error locking device of the hand-crank mechanism, but the distribution network requires frequent operations, and this unlocking method is not convenient enough. In addition, due to the lack of effective supervision of the personnel on the operation site, it is not clear what the actual geographical location of the on-site operators is, nor is it clear whether the operators are operating the correct equipment. Therefore, operational accidents caused by human factors still occur from time to time. It can be seen that the control accuracy of the anti-error locking of the existing trolley-type switch cabinet is low. Summary of the invention

[0006] The object of the present invention is to provide a method and device, equipment and storage medium for preventing accidental locking of a trolley-type switch cabinet, which can make the unlocking method more convenient and improve the control accuracy of preventing accidental locking of the trolley-type switch cabinet.

[0011] Calculating a matching degree between the first switch cabinet information and the second switch cabinet information;

[0012] When the matching degree reaches a specified threshold, an unlocking instruction is sent to the switch cabinet;

[0013] When the unlocking information fed back by the switch cabinet in response to the unlocking instruction is received, prompt information is output, where the prompt information is used to prompt the user to insert the hand-crank mechanism into the crank hole of the switch cabinet trolley to operate the trolley.

[0014] The second aspect of the present invention discloses a trolley-type switch cabinet anti-mislocking control device, comprising:

[0015] A receiving unit, used to receive the operation tasks sent by the scheduling background;

[0016] a determining unit, configured to determine first switch cabinet information according to the switch cabinet task when the operation task is a switch cabinet task;

[0018] A matching unit, used to calculate the matching degree between the first switch cabinet information and the second switch cabinet information;

[0019] An unlocking unit, used for sending an unlocking instruction to the switch cabinet when the matching degree reaches a specified threshold;

[0020] The prompt unit is used to output prompt information when receiving the unlocking information fed back by the switch cabinet in response to the unlocking instruction, wherein the prompt information is used to prompt the user to insert the hand-crank mechanism into the crank hole of the switch cabinet trolley to operate the trolley.

[0021] The third aspect of the present invention discloses a handheld intelligent device, comprising a memory storing executable program code and a processor coupled to the memory; the processor calls the executable program code stored in the memory to execute the anti-mislocking control method of the trolley-type switch cabinet disclosed in the first aspect.

[0022] A fourth aspect of the present invention discloses a computer-readable storage medium storing a computer program, wherein the computer program enables a computer to execute the anti-mislocking control method for a trolley-type switch cabinet disclosed in the first aspect.

[0023] The beneficial effect of the present invention lies in that the provided trolley-type switch cabinet anti-misoperation locking control method and device, equipment, and storage medium receive the operation task sent by the scheduling background. When the operation task is a switch cabinet task, the switch cabinet information specified by the task is determined according to the switch cabinet task, and then when the radio frequency signal sent by the electronic tag on the switch cabinet is detected, the camera module is turned on to scan the identification code information on the switch cabinet to obtain the switch cabinet information on the spot. When the matching degree of the two switch cabinet information reaches the specified threshold, an unlocking instruction is sent to the switch cabinet. When the unlocking information fed back by the switch cabinet is received, a prompt message is output to prompt the user to insert the hand-cranking mechanism into the cranking hole of the switch cabinet trolley to operate the trolley, so that after arriving at the site, the switch cabinet information can be scanned and matched with the switch cabinet information specified by the task, so as to realize automatic wireless anti-misoperation locking, and there is no need to use an unlocking key to unlock the switch cabinet, which can make the unlocking method more convenient, and at the same time avoid the problem of the operator operating the wrong equipment as much as possible, and can improve the control accuracy of the trolley-type switch cabinet anti-misoperation locking.

[0035] The embodiment of the present invention discloses a method for preventing mislocking of a trolley-type switch cabinet. The execution subject of the method can be a handheld smart device such as a computer, a laptop, a tablet computer, or a trolley-type switch cabinet mislocking control device embedded in the handheld smart device, and the present invention does not limit this. In this embodiment, a handheld smart device is used as an example for explanation.

[0036] like Figure 1 As shown, the method includes the following steps 110 to 160:

[0037] 110. The handheld smart device receives the operation task sent by the scheduling background.

[0038] In an embodiment of the present invention, the handheld smart device can be a mobile terminal carried by the operator, and the handheld smart device has a built-in application for the operator to execute the electronic operation ticket on site. The handheld smart device is wirelessly connected to the remote dispatch background. Generally, after the dispatch background generates an electronic operation ticket including one or more operation tasks, it is sent to the handheld smart device of the operator via wireless transmission. After that, the operator carries the handheld smart device to the site to perform the operation. When the handheld smart device receives the operation task sent by the dispatch background, the handheld smart device can first identify the operation task.

[0039] 120. When the operation task is a switch cabinet task, the handheld smart device determines first switch cabinet information according to the switch cabinet task.

[0040] If the operation task is identified as a switch cabinet task, the handheld smart device determines the first switch cabinet information according to the switch cabinet task. The first switch cabinet information is the relevant equipment information of the reserved switch cabinet under the task, including the province, city, district, station name, voltage level, line name and other information.

[0041] 130. When the handheld smart device detects the radio frequency signal sent by the electronic tag on the switch cabinet, the handheld smart device turns on its own camera module to scan the identification code information on the switch cabinet to obtain the second switch cabinet information.

[0042] In an embodiment of the present invention, an electronic tag, i.e., a radio frequency identification (RFID) device, is provided on the switch cabinet to identify the switch cabinet. Before using the hand-crank mechanism to operate the trolley-type switch cabinet, the switch cabinet identity needs to be verified. When the handheld smart device detects the radio frequency signal sent by the electronic tag on the switch cabinet, it indicates that the operator has brought the handheld smart device to the vicinity of the switch cabinet. At this time, the operator can control the handheld smart device to turn on the camera module, or the handheld smart device can automatically turn on its own camera module to scan the identification code set on the switch cabinet, such as a QR code or a barcode, so as to obtain the relevant equipment information of the on-site switch cabinet, i.e., the second switch cabinet information.

[0043] 140. The handheld smart device calculates a matching degree between the first switch cabinet information and the second switch cabinet information.

[0044] As an optional implementation, step 140 may include the following steps 1401 to 1404:

[0045] 1401. Extract a first input vector according to first switch cabinet information, and extract a second input vector according to second switch cabinet information.

[0046] Among them, a learning algorithm that converts text into a corresponding vector can be used. For example, through the sklearn library in Python, the switch cabinet information is converted into an input vector in the form of bag-of-words model features; wherein Python is a computer programming language; sklearn, also known as scikit-learn, is a python-based machine learning library that can facilitate the implementation of machine learning algorithms, including: classification, regression, clustering, dimensionality reduction, model selection and preprocessing and other data mining related algorithms.

[0047] 1402. Input the first input vector into a pre-built coding model to obtain a first feature vector, and input the second input vector into the coding model to obtain a second feature vector.

[0048] Among them, the encoding model is specifically a model obtained by training a neural network, which can encode and decode the input vector to convert it into a corresponding feature vector. The first feature vector and the second feature vector can retain a large amount of information of the original input vector and are used to represent the feature information of the first switch cabinet information and the second switch cabinet information.

[0049] 1403. Calculate the vector similarity between the first eigenvector and the second eigenvector.

[0050] Regarding the calculation of vector similarity, the distance between two vectors is usually calculated. The closer the distance, the greater the similarity. The cosine similarity calculation method can be used to calculate the cosine similarity between the first eigenvector and the second eigenvector, and then determine the vector similarity of the two based on the cosine similarity.

[0051] Among them, cosine similarity is usually used in positive space, so the value given is between 0 and 1. When two vectors have the same direction and the angle between them is 0 degrees, the cosine similarity is the highest and the value is 1; when the two vectors point in completely opposite directions, the cosine similarity value is -1; when the angle between the two vectors is 90°, the cosine similarity value is 0.

[0052] 1404. A logistic regression model is obtained according to the second switch cabinet information and preset keyword training, and the vector similarity is input into the logistic regression model to obtain the matching degree between the first switch cabinet information and the second switch cabinet information.

[0053] Among them, firstly, the parameters of the logistic regression model are calculated by the second switch cabinet information and the preset keywords, and then the vector similarity obtained in step 1403 is input into the logistic regression model, and a matching degree value is output to obtain the matching degree of the two. The matching degree can be expressed as a percentage value, such as 60%, 70%, 86%, etc.

[0054] 150. When the matching degree reaches a specified threshold, the handheld smart device sends an unlocking command to the switch cabinet.

[0055] By matching the first switch cabinet information with the second switch cabinet information, the equipment can be checked to avoid operating the wrong equipment. If the matching degree of the two reaches the specified threshold, it is considered that the comparison is consistent, and the handheld smart device can send an unlocking command to the switch cabinet. If the matching degree of the two is less than the specified threshold, it is considered that the comparison is inconsistent, which means that the operator may have walked into the wrong equipment interval and will operate the wrong equipment. Then it will not be unlocked. When the anti-mistake locking device set in the switch cabinet is in the locked state, the switch cabinet cannot be operated.

[0056] 160. When receiving the unlocking information fed back by the switch cabinet in response to the unlocking instruction, the handheld smart device outputs a prompting information, where the prompting information is used to prompt the user to insert the hand-cranking mechanism into the cranking hole of the switch cabinet trolley to operate the trolley.

[0057] When the unlocking information fed back by the switch cabinet in response to the unlocking instruction is received, it means that the switch cabinet has been unlocked. Specifically, the anti-mislocking device of the switch cabinet is arranged on the hand-crank mechanism of its trolley. When the hand-crank mechanism is unlocked, the hand-crank mechanism can be inserted into the trolley's crank hole. At this time, by using external force to shake the hand-crank mechanism, the trolley can be operated to enter and exit the switch cabinet to realize the switch control of the switch cabinet. At this time, the handheld smart device can output a prompt message to prompt the user to insert the hand-crank mechanism into the crank hole of the switch cabinet trolley to operate the trolley. The purpose of the trolley operation is to turn on or off the switch of the switch cabinet.

[0058] As an optional implementation, after the handheld smart device outputs the prompt information, the following steps 171 to 174 may also be performed:

[0059] 171. The handheld intelligent device obtains the sensor signal collected by the sensor installed in the swing hole of the switch cabinet trolley.

[0060] 172. The handheld intelligent device determines whether the hand-crank mechanism has been inserted into the crank hole of the switch cabinet trolley based on the sensor signal.

[0061] 173. If it has been inserted, the handheld smart device determines whether the trolley is in place.

[0062] A distance sensor, such as an infrared sensor or a laser sensor, may be provided in the swing hole of the switch cabinet trolley. When a hand-crank mechanism enters the swing hole, the sensing signal of the distance sensor will change in a certain regular pattern. Therefore, it can be determined whether an obstacle is detected based on the sensing signal of the distance sensor. When it is determined that an obstacle is detected based on the sensing signal, it is determined that the hand-crank mechanism has been inserted into the swing hole of the switch cabinet trolley; otherwise, it is determined that the hand-crank mechanism has not been inserted into the swing hole of the switch cabinet trolley.

[0063] Furthermore, after determining that the hand-crank mechanism has been inserted into the crank hole of the switch cabinet trolley, it can be determined whether the trolley has been fully operated. Specifically, the implementation method for determining whether the trolley has been fully operated can be: obtaining the rotation angle and torque of the hand-crank mechanism during the trolley operation; if the rotation angle reaches a preset angle and the torque is greater than a specified threshold, the trolley is determined to be fully operated. By performing "AND" logic on the rotation angle and the torque to determine whether the trolley has been fully operated, the accuracy of the determination can be improved.

[0064] Preferably, before obtaining the rotation angle and torque of the hand-cranked mechanism during the operation of the trolley, the target separation and combination state of the trolley can be determined according to the operation task sent by the scheduling background, and then whether the initial separation and combination state before the trolley operation is opposite to the target separation and combination state; if the initial separation and combination state is opposite to the target separation and combination state, the rotation angle and torque of the hand-cranked mechanism during the operation of the trolley are obtained for judgment.

[0065] The target opening and closing state is specifically open or closed; generally speaking, if the target opening and closing state is closed, then the initial opening and closing state of the trolley should be the opposite opening; if the target opening and closing state is open, then the initial opening and closing state of the trolley should be the opposite closing. If the target opening and closing state is different from the initial opening and closing state, it is considered to be opposite. Through this preferred embodiment, the "AND" logic can be combined with the judgment of the initial opening and closing state of the trolley to judge whether the trolley is in place, thereby further improving the judgment accuracy.

[0066] 174. If the trolley is operated properly, the handheld intelligent device sends a locking command to the switch cabinet.

[0067] In this step, if the trolley operation is in place and the handheld smart device determines that the trolley operation is completed, a locking instruction is sent to the switch cabinet. In addition, the handheld smart device can also upload the operation completion information to the dispatch background to synchronize the device status. Preferably, if the trolley operation is in place and before the handheld smart device sends the locking instruction to the switch cabinet, it can also determine whether the current opening and closing state after the trolley operation is consistent with the target opening and closing state. If they are consistent, it is determined that the current operation task has been completed, and a locking instruction is sent to the switch cabinet, and the trolley is remotely locked to complete the operation closed loop. At the same time as the task is completed, the operation completion information is uploaded to the dispatch background to synchronize the device status.

[0068] In summary, by implementing the embodiments of the present invention, after arriving at the site, the switch cabinet information can be scanned and matched with the switch cabinet information specified by the task, so as to realize automatic wireless anti-mistake locking. There is no need to use an unlocking key to unlock the switch cabinet, which can make the unlocking method more convenient and avoid the problem of the operator operating the wrong equipment as much as possible, thereby improving the control accuracy of the anti-mistake locking of the trolley-type switch cabinet.
