[0015] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with embodiments.

[0016] The robot inspection data and equipment uploaded data comparison verification system comprises an electric appliance cabinet monitoring system located in an electric appliance cabinet, which is used for monitoring the operation of the electric appliance in the electric appliance cabinet. The electric appliance cabinet monitoring system mainly comprises a microprocessor module, a monitoring element and a first communication module. The electric appliance cabinet monitoring system obtains monitoring data related to the operation of the electric appliance in the electric appliance cabinet through the monitoring element, including the temperature in the electric appliance cabinet, the temperature of the circuit board, the current, the voltage and the like. The robot inspection data and equipment uploaded data comparison verification system further comprises a server located outside the electric appliance cabinet. The electric appliance cabinet monitoring system transmits the monitoring data monitored by the monitoring element to the server through the first communication module. The data processing module of the server compares the monitoring data with the standard data stored in the storage module of the server. If the difference is within the allowable range, it is considered that the electric appliance cabinet is operating normally, otherwise it is considered that the electric appliance cabinet may be faulty. The storage module of the server also stores the location information of the electric appliance cabinet. When the electric appliance cabinet may be faulty, the server retrieves the location information of the electric appliance cabinet that may be faulty. This design is prior art, so it is not described in detail here.

[0017] The robot inspection data and equipment uploaded data comparison verification system further comprises an inspection robot with walking ability located outside the electric appliance cabinet. The electric appliance cabinet instrument group is redundantly arranged in the electric appliance cabinet. Each electric appliance cabinet instrument in the electric appliance cabinet instrument group has an indication window. An electric appliance cabinet instrument window is further arranged on the electric appliance cabinet. Each indication window of the electric appliance cabinet instrument group is arranged in an electric appliance cabinet instrument window. The inspection robot has a camera device. The position of the electric appliance cabinet instrument window is located on one side of the walking track of the inspection robot. The height of the electric appliance cabinet instrument window is adapted to the height of the camera head of the camera device. The inspection robot has a second communication module. The inspection robot captures the image at the electric appliance cabinet instrument window through the camera device and transmits the image to the server through the second communication module. The server obtains the inspection data after analyzing and processing the image.

[0018] The server compares and verifies the inspection data, the monitoring data and the standard data to determine the cause of the fault.

[0019] In the embodiment 1, when the server does not receive the monitoring data after the server exceeds the specified time, the server issues a restart command to the electrical cabinet monitoring system. If the server receives the monitoring data within the set time after the restart command is issued, the server considers that the electrical cabinet monitoring system is normal and does not need to be maintained, but records the time when the restart command is issued and the time when the monitoring data is received again, for predicting the performance of the electrical cabinet monitoring system, such as frequent restarts, which indicates poor performance. If the server still does not receive the monitoring data after the set time after the restart command is issued, the server considers that the device is suspected to be faulty, and the fault type is A. In the case of the fault type A, the server issues the location of the suspected faulty device to the inspection robot, and the inspection robot walks to the suspected faulty device and takes an image of the instrument window of the electrical cabinet. At the same time, the server issues a command to retrieve the monitoring data to the inspection robot. The electrical cabinet monitoring system and the inspection robot both have a Bluetooth communication module. After receiving the command to retrieve the monitoring data, the inspection robot acquires the monitoring data of the electrical cabinet monitoring system through the Bluetooth communication module and uploads the monitoring data to the server. If the server can receive the monitoring data from the inspection robot, the server considers that the fault reason is a data transmission line fault. If the server does not receive the monitoring data from the inspection robot or the inspection robot feedbacks that reading the monitoring data fails, it is considered that the fault reason is that the electrical cabinet monitoring system is damaged. Regardless of whether the server obtains the monitoring data from the inspection robot, the server compares the inspection data with the standard data. If the difference is within the allowed range, it is considered that the electrical cabinet is running normally, otherwise it is considered that the electrical cabinet is faulty.

[0020] In the embodiment 2, when there is missing data in the monitoring data, the server considers that the device is suspected to be faulty, the fault type is B, in the case of the fault type B, the server issues the location of the suspected faulty device to the inspection robot, the inspection robot walks to the suspected faulty device, and takes an image at the instrument window of the electrical cabinet. Meanwhile, the server issues a command to the inspection robot to retrieve the monitoring data, the electrical cabinet monitoring system and the inspection robot both have a Bluetooth communication module, after receiving the command to retrieve the monitoring data, the inspection robot acquires the monitoring data of the electrical cabinet monitoring system through the Bluetooth communication module, and uploads the monitoring data to the server. If the server receives the monitoring data from the inspection robot, the server considers that the fault reason is a data transmission line fault, and issues a restart command to the electrical cabinet monitoring system. If the server receives the monitoring data within the set time after the restart command is issued, the server considers that the electrical cabinet monitoring system is normal and does not need to be maintained, but records the time when the restart command is issued and the time when the monitoring data is received again, for predicting the performance of the electrical cabinet monitoring system, such as frequent restarts, which indicates poor performance. If the server receives the monitoring data from the inspection robot, which is consistent with the missing part of the monitoring data from the electrical cabinet monitoring system, the server compares the inspection data with the standard data, if the difference is within the allowed range, the server considers that the electrical cabinet monitoring system is faulty, otherwise, the server considers that the electrical appliance in the electrical cabinet is faulty.

[0021] In the embodiment 3, when there is data with a difference greater than a set value in the two monitoring data within a specified time, the server considers that the device is suspected to be faulty, the fault type is C. In the case of the fault type C, if the difference between the two monitoring data and the standard data is within the allowed range, the server records the monitoring data and the time when the monitoring data occurs, for predicting the operation of the electrical appliance in the electrical cabinet or adjusting the standard data. If at least one monitoring data is beyond the allowed range, the server issues the location of the suspected faulty device to the inspection robot, the inspection robot walks to the suspected faulty device, and takes an image at the instrument window of the electrical cabinet. If the difference between the inspection data and the standard data is also beyond the allowed range, the server considers that the electrical appliance in the electrical cabinet is faulty, if the difference between the inspection data and the standard data is within the allowed range, the server issues a command to take an image again after a specified time, the inspection robot takes an image again after the specified time, if the difference between the second inspection data and the standard data is within the allowed range, the server records the monitoring data and the time when the monitoring data occurs, for predicting the operation of the electrical appliance in the electrical cabinet or adjusting the standard data. If the difference between the second inspection data and the standard data is beyond the allowed range, the server considers that the electrical appliance in the electrical cabinet is faulty.

[0022] In the three embodiments, the electrical cabinet monitoring system uploads monitoring data to the server every 1-10 minutes. Thus, energy consumption is reduced. Preferably, the specified time in the three embodiments is the same as the interval time, and the set time in the three embodiments is not less than the interval time.

[0023] In the three embodiments, the electrical cabinet monitoring system is powered by a power supply system independent of the electrical cabinet. Thus, the problem of being difficult to distinguish the damage cause when the power supply system is damaged is solved.

[0024] In the three embodiments, the communication protocols used by the first communication module and the second communication module are different. Thus, the situation that both communication modules cannot work normally due to the interruption of the communication line is avoided. Preferably, the first communication module is a wifi communication module, and the second communication module is a 5G communication module.

[0025] In the three embodiments, a two-dimensional code is provided on the electrical cabinet instrument window, the two-dimensional code contains the identification information of the electrical cabinet, the image taken by the inspection robot contains the two-dimensional code, the server identifies the two-dimensional code and associates the identification information of the electrical cabinet with the inspection data. Thus, the server can determine whether the electrical cabinet where the image taken by the inspection robot is located is accurate. At the same time, during daily inspection, the server uses the two-dimensional code to determine the position of the inspection robot, so as to plan the optimal walking route for the inspection robot to reach the suspected faulty electrical cabinet more quickly when a fault occurs.

[0026] In the three embodiments, the monitoring element is a temperature sensor, which is preferably a diode temperature sensing probe (model MF5C) of Shenzhen Kepengda Electronics Co., Ltd. or a platinum resistance temperature sensor (model WZP-187) of Yancheng Songda Thermal Instrument Co., Ltd. The electrical cabinet instrument is a liquid thermometer. The color of the liquid in the liquid thermometer is preferably red, so that it is more convenient to identify. In order to facilitate night identification or identification in a dark environment inside the electrical cabinet, a fluorescent agent is provided at the scale value of the liquid thermometer. The monitoring element can also be a current sensor, which is preferably a Hall effect current sensor (model CC6904SO-20A) of Shenzhen Pengchuangxin Source Electronics Technology Co., Ltd. The electrical cabinet instrument is an ammeter, and the hands and dial of the ammeter are coated with a fluorescent agent. The ammeter has a probe, and different lengths of probes can be selected, so that the indication window is located at the electrical cabinet window while measuring the electrical appliances at a distance. For the liquid thermometer, since the temperature measuring part is usually on the thermometer, a heat-conducting wire with good heat conductivity can be used to connect the temperature measuring part with the electrical appliances to obtain the temperature of the electrical appliances at a distance. The liquid thermometer can also be located at the electrical appliances, and a mirror is used to reflect the image of the liquid thermometer to the electrical cabinet instrument window.

[0027] In the above three embodiments, the server obtains data through image analysis, which is existing technology, so its technical principle will not be described in detail. The innovation of this invention is not in obtaining inspection data through image analysis, but in comparing the inspection data with the monitoring data to determine the cause of the fault.

[0028] In the three embodiments described above, the indicator window of the electrical cabinet instrument refers to the side from which the user can observe the temperature reading, such as the cover of an ammeter. LED strips may be provided around the instrument window, with the strips facing the indicator window. Alternatively, the inspection robot may be equipped with supplementary lighting; when taking images, the robot activates the supplementary lighting to illuminate the indicator window behind the electrical cabinet instrument window.

[0029] In the three embodiments described above, the movement of the inspection robot is existing technology, as are obstacle avoidance, determination of the target location, and planning of the movement path; therefore, these will not be described in detail. The inspection robot itself can also determine the accuracy of its location by recognizing a QR code. If it cannot recognize the QR code, it indicates that the location or orientation is incorrect. If the location obtained from the recognized QR code does not match the location of the suspected faulty device, it continues to move without uploading the captured image. If the location obtained from the recognized QR code matches the location of the suspected faulty device, it uploads the captured image.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
