[0042] The technical solution of the embodiment of the present application is introduced below.

[0043] With the development of informatization and intelligence of power systems, more and more distribution rooms are introducing intelligent inspection robots to replace manual inspections to check whether power equipment is operating normally. This can reduce labor costs and achieve 24-hour uninterrupted inspections through robots to avoid accidents.

[0044] However, due to the wide variety of equipment in the distribution room, the manual debugging process of the inspection robot is very cumbersome and lengthy. Every time a new device is added to the distribution room, the robot needs to be re-familiarized with the updated equipment distribution of the distribution room. At the same time, in order to avoid errors in the robot program, a dedicated person is required to supervise it during its work, which in turn brings a huge workload to the staff.

[0045] To solve the above problems, please refer to Figure 1 , Figure 1 1 is a schematic block diagram of a patrol circuit provided in an embodiment of the present application. Figure 1 As shown, the inspection circuit 10 includes: a control unit 11 , a communication unit 12 and an interface unit 13 .

[0046] The inspection circuit 10 is used for each power distribution device 21 in the power distribution room 20 to be inspected (the present application does not limit the number of power distribution devices 21, wherein Figure 1 Only the connection mode with one of the power distribution equipment 21 is shown) for inspection, such as Figure 1 As shown, the communication unit 12 is communicatively connected with the power distribution equipment 21, and the interface unit 13 is electrically connected with the power distribution equipment 21. Then, the control unit 11 combines the information obtained by the communication unit 12 and the interface unit 13 under normal operation to construct a device model for each power distribution equipment, and then combines the device model and the equipment inspection parameters during daily use to complete accurate, real-time and uninterrupted inspection of each power distribution equipment.

[0047] In some embodiments, the control unit 11 may be a microcontroller unit (MCU) or other chips with processing capabilities or any controller equipped with the above chips.

[0048] In some embodiments, the inspection circuit 10 can be mounted on an inspection robot or any inspection equipment or handheld inspection terminal. At the same time, the distribution room 20 can also be equipped with a variety of different / same types of equipment equipped with the inspection circuit 10 for coordinated use to improve the efficiency of the inspection.

The embodiment of the present application does not limit the type of the communication unit 12). The control unit 11 is an MCU, and the communication unit 12 and the control unit 11 are powered by a first power supply VCC1. At the same time, the interface unit 13 includes multiple interfaces for connecting to a power distribution device as shown in the figure. At the same time, the interface unit 13 is also connected to a second power supply VCC2 for powering it as a backup power supply.

[0050] Combination Figure 1-Figure 2 Please refer to the inspection circuit provided in the corresponding embodiment. Figure 3 , Figure 3 The figure is a flow chart of a power distribution room inspection method provided in an embodiment of the present application. The power distribution room inspection method in an embodiment of the present application can be applied to the control unit of the inspection circuit provided in an embodiment of the present application. Figure 3 As shown, the power distribution room inspection method of this embodiment includes steps S301 to S305, which are described in detail as follows:

[0051] Step S301: Control the interface unit to be electrically connected to each power distribution device in the power distribution room to be inspected, and obtain the electrical parameters of each power distribution device.

[0052] Specifically, the control unit controls the interface unit to electrically connect with each normally operating distribution device in turn according to the type of its interface (whether multiple interfaces can be connected at the same time) and the distance from the distribution device, and then obtains the electrical parameters corresponding to each distribution device to determine the working conditions of the circuits inside each distribution device.

[0053] In some embodiments, the inspection circuit also includes a detection unit, which is electrically connected to each distribution equipment in the distribution room to be inspected via an interface unit; obtaining the electrical parameters of each distribution equipment includes: obtaining the initial parameters of the detection unit before it is electrically connected to the distribution equipment; obtaining the connection parameters of the detection unit after it is electrically connected to the distribution equipment; and obtaining the electrical parameters of the distribution equipment based on the initial parameters and the connection parameters.

[0054] By forming a detection unit through detection circuits such as voltage / current / power, the electrical parameters corresponding to each distribution device can be quickly determined based on the change from initial parameters to connection parameters before and after the connection each time the interface unit is electrically connected to the distribution device.

[0055] In some embodiments, before the control interface unit is electrically connected to each power distribution device in the power distribution room to be inspected, the control unit further includes: obtaining interface information of the power distribution device, and confirming the target interface in the interface unit that is electrically connected to the power distribution device according to the interface information of the power distribution device, so as to control the interface unit to be electrically connected to the power distribution device through the target interface. Thus, when connecting to each power distribution device, the control unit can confirm the most appropriate target interface to ensure normal connection with the power distribution device.

[0056] Step S302: Control the communication unit to establish communication connection with each power distribution device in the power distribution room to be inspected, and obtain specification parameters of each power distribution device.

[0057] Specifically, the control unit communicates with each power distribution device in normal operation in the power distribution room by controlling the communication unit, and can obtain the specification parameters corresponding to each power distribution device. For example, by controlling the communication unit to send a specification request instruction to the power distribution device, the specification parameters corresponding to the power distribution device (including but not limited to various characteristics of the power distribution device such as purpose, type, and size) are obtained according to the information returned by the received power distribution device. Then, through steps S301 and S302, the control unit can determine the specification parameters and electrical parameters of the normal operation of each power distribution device, so as to prepare for the subsequent inspection.

[0058] In some embodiments, the communication unit is controlled to communicate with each power distribution device in the distribution room to be inspected to obtain specification parameters of each power distribution device, including: generating a specification acquisition instruction according to a preset equipment specification information table; controlling the communication unit to send the specification acquisition instruction to each power distribution device to obtain the initial specification information returned by the power distribution device; obtaining the communication connection protocol between the communication unit and the power distribution device; parsing the initial specification information according to the communication connection protocol to obtain the specification parameters of each power distribution device.

[0059] By pre-storing a device specification information table in the control unit, the specification acquisition instruction is the type of specification to be obtained or its corresponding code, and then by obtaining the communication connection protocol between the communication unit and the power distribution equipment, the initial specification information received by sending the specification acquisition instruction can be parsed, and the specification parameters corresponding to the power distribution equipment can be accurately obtained.

[0060] Exemplarily, before the control communication unit sends the specification acquisition instruction to each power distribution device, the method further includes modifying the format of the specification acquisition instruction according to the communication connection protocol to send the modified specification acquisition instruction to each power distribution device. The method provided can ensure that the specification acquisition instruction can be correctly interpreted by the power distribution device.

[0061] Step S303: construct a device model corresponding to each power distribution device according to the electrical parameters and specification parameters of each power distribution device.

[0062] Specifically, after obtaining the electrical parameters and specification parameters of the power distribution equipment under normal operation, the above parameters are used as training samples to construct the initial model to be trained, and the intelligent device model corresponding to each power distribution equipment is obtained. This model can be used to determine whether the power distribution equipment is in normal operation.

[0063] In some embodiments, the electrical parameters include at least voltage parameters and power parameters, and the control unit stores a preset model library, in which a plurality of initial models and model feature information of each initial model are stored; a device model corresponding to each power distribution device is constructed according to the electrical parameters and specification parameters of each power distribution device, including: calculating the model matching degree between the specification parameters of each power distribution device and the model feature information of each initial model; determining the target initial model corresponding to each power distribution device according to the model matching degree; completing the construction of the target initial model according to the voltage parameters and power parameters corresponding to each power distribution device, and obtaining the device model corresponding to the power distribution device.

[0064] Initial models such as neural network models, support vector machine models, Transformer models and other types of models. At the same time, due to the various specifications of power distribution equipment, different models will have better inspection effects on power distribution equipment of one specification. Therefore, this application specifically calculates the model matching degree between the specification parameters of each power distribution equipment and the model feature information of each initial model, and determines the target initial model corresponding to each power distribution equipment according to the model matching degree, so as to determine that the device model constructed by each power distribution equipment is based on its most suitable initial model, thereby improving the accuracy of subsequent inspections of the power distribution equipment.

[0065] Exemplarily, calculating the model matching degree between the specification parameters of each power distribution equipment and the model characteristic information of each initial model includes: parsing the specification parameters to obtain the type parameters and the use parameters corresponding to the specification parameters; respectively obtaining the type coding vector corresponding to the type parameters, the use coding vector corresponding to the use parameters, and the feature coding vector corresponding to the model characteristic information; calculating the model matching degree according to the feature coding vector, the type coding vector, and the use coding vector; the expression of the model matching degree includes:

[0066] ; Wherein, K is the model matching degree, A is the power distribution equipment, M is the initial model, is the feature encoding vector, is the type encoding vector, Encode the vector for the stated purpose, is the first preset threshold, is the second preset threshold, is the third preset threshold, and e is the base of the natural logarithm.

[0067] By combining the type and purpose of the distribution equipment with the characteristics of the initial model, the matching degree is calculated. For example, the matching degree between the characteristics and the type is calculated by the class index method, and then the matching degree between the characteristics and the purpose is calculated by the index method to obtain the final model matching degree K. The reason for adopting the above method is that the purpose is more abstract than the type, and the sampling index method may not get the final result close to the actual matching degree. At the same time, due to the large workload of equipment inspection and the need for uninterrupted inspection, an overly complex algorithm will lead to a long inspection interval, affecting the inspection efficiency.

[0068] Exemplarily, the target initial model is constructed according to the voltage parameters and power parameters corresponding to each power distribution equipment, including: randomly generating a test voltage and a test power; inputting the test voltage and the test power into the target initial model to be constructed, and obtaining the inspection prediction results output by the target initial model; obtaining the voltage deviation value according to the test voltage and the voltage parameters, and obtaining the power deviation value according to the test power and the power parameters; obtaining the actual inspection results according to the voltage deviation value and the power deviation value; optimizing the target initial model according to the inspection prediction results and the actual inspection results, and obtaining the constructed equipment model.

[0069] The corresponding inspection prediction structure is obtained based on the test voltage and test power of the normal operation of the distribution equipment, and then the actual inspection results are judged by combining the deviations corresponding to multiple groups of test voltages and test powers of the real-time strategy, so as to train the target initial model until convergence through methods such as calculating the loss function. Then the initial model of each distribution equipment is constructed.

[0070] Step S304: Control the communication unit to send an inspection instruction to each power distribution device according to a preset inspection interval, and obtain the device inspection parameters returned by each power distribution device.

[0071] Specifically, the communication unit is controlled to send an inspection instruction to each power distribution device according to a preset inspection interval (such as an interval of 10 minutes), and then the inspection parameters returned by each power distribution device are obtained. The inspection parameters may include inspection electrical parameters (real-time voltage, current, power and other information, obtained through internal self-inspection of the power distribution device or access detection through the control interface unit) and inspection equipment parameters (such as communication connection status, operating status and other parameters). Then, the current status of the device can be confirmed based on the device inspection parameters combined with the corresponding device model.

[0072] In some embodiments, the inspection circuit is mounted on an inspection robot. Before controlling the communication unit to send an inspection instruction to each distribution device according to a preset inspection interval, it also includes: obtaining map information obtained by the inspection robot during the inspection of the distribution room; obtaining the equipment location information of each distribution device obtained by the inspection robot when it is electrically connected to each distribution device; and constructing a visual inspection model of the distribution room based on the map information, the equipment location information of each distribution device and the equipment model of each distribution device, so as to obtain the inspection results of each distribution device in the distribution room through the visual inspection model.

[0073] By installing the inspection circuit in the inspection robot, the robot positioning technology can be combined to build a two-dimensional / three-dimensional visualization model of the distribution room, which can help managers quickly confirm the status of each distribution equipment in the distribution room and improve the work efficiency of managers.

[0074] Step S305, input the equipment inspection parameters into the equipment model of the corresponding power distribution equipment, and the equipment model outputs the inspection results of the power distribution equipment to complete the inspection of each power distribution equipment.

[0075] Specifically, by inputting the equipment inspection parameters of the power distribution equipment into the corresponding equipment model, the inspection of each power distribution equipment can be completed according to the inspection results output by the model. Then the equipment model can determine that the currently input inspection parameters are the parameters corresponding to the normal / abnormal power distribution equipment. At the same time, the present application can also adjust the inspection interval according to the inspection results, such as increasing the frequency of sending inspection instructions for abnormal or suspicious power distribution equipment, and reducing the frequency of sending inspection instructions for power distribution equipment that has been normal for many consecutive times. Then, intelligent, efficient and uninterrupted inspection of the power distribution room is realized.

[0076] In some embodiments, after the equipment model outputs the inspection results of the power distribution equipment, it also includes: if it is determined that the power distribution equipment is abnormal based on the inspection results, parsing the inspection results to obtain abnormal inspection parameters of the power distribution equipment; extracting equipment characteristic information of the power distribution equipment from the equipment model of the power distribution equipment; inputting the abnormal inspection parameters and equipment characteristic information into a preset abnormal repair model to obtain the corresponding repair plan for the power distribution equipment, so as to complete the abnormal repair of the power distribution equipment according to the repair plan.

[0077] When there is an abnormality in the power distribution equipment, the provided method can extract the equipment characteristic information of the power distribution equipment from the equipment model (such as equipment purpose, equipment function, etc., which are used to characterize the structure, working mode and other aspects of the power distribution equipment), and then input the abnormal inspection parameters and equipment characteristic information into the abnormal repair model trained by multiple historical maintenance data, which can quickly determine the repair plan of the power distribution equipment, control the maintenance robot to perform rapid maintenance or send it to the maintenance personnel for maintenance. Therefore, the provided method not only improves the efficiency of inspection but also improves the efficiency of maintenance.

[0078] The present application provides a distribution room inspection method, which is applied to a control unit of an inspection circuit, and the inspection circuit also includes a communication unit and an interface unit; the method first controls the interface unit to be electrically connected to each distribution device in the distribution room to be inspected, and obtains the electrical parameters of each distribution device; then controls the communication unit to communicate with each distribution device in the distribution room to be inspected, and obtains the specification parameters of each distribution device; then, a device model corresponding to each distribution device is constructed according to the electrical parameters and specification parameters of each distribution device; secondly, the communication unit is controlled to send an inspection instruction to each distribution device according to a preset inspection interval, and obtains the device inspection parameters returned by each distribution device; finally, the device inspection parameters are input into the device model of the corresponding distribution device, and the device model outputs the inspection results of the distribution equipment, thereby completing the inspection of each distribution equipment.

[0079] Furthermore, the provided method can generate corresponding equipment models for different equipment in the scenario of a distribution room where there are many types of equipment and 24-hour inspection is required. Then, the inspection results of each distribution equipment can be confirmed by inputting its equipment inspection parameters into the equipment model, thereby completing accurate inspections of each distribution equipment in the distribution room quickly, efficiently and continuously.
