Description

Technical Field

[0001] The present invention relates to the technical field of electric power monitoring, and in particular to an electric power monitoring network security intelligent inspection system and method. Background Art

[0002] At present, with the rapid development of urban construction and urbanization, the coverage of power networks, the number of power equipment, and the distance of transmission lines are increasing rapidly. In order to reduce the number of inspection personnel for the operation and maintenance of power systems in the existing technology, it is often necessary to rely on a large number of auxiliary monitoring equipment, such as inspection robots, drones, and various sensors. This requires not only high equipment installation and maintenance costs, but also the need to process massive amounts of collected data through the combination of intelligent algorithms. Massive data transmission also has the problems of data loss and delay. Therefore, it is particularly important to develop a safer, smarter and lower-cost power monitoring network security inspection system.

[0003] In the prior art, invention patent CN104218679A proposes a remote automatic inspection method for substations based on a remote viewing system. By comparing the status information of the monitored power equipment during the real-time / historical inspection process, the remote equipment status is confirmed, and the real-time database equipment status information is updated in the historical inspection image database for use in updating the plan. However, the invention requires a large amount of image analysis and inspection data processing, and the operating parameters of the equipment in the power grid are often dynamically changing, and the operating status parameter data in the same period are often different. The above technical solution cannot effectively process and compare dynamic data.

[0004] In the prior art, invention patent CN105488863A proposes a static inspection system for cable wells, which collects data such as impact and environmental information in the cable well, and then transmits and processes the collected data, thereby reducing the reliance on manual inspections and improving inspection efficiency. However, the above scheme only collects images and environmental data of equipment and cables in the cable well, but a large amount of collected images and data need to be processed manually or in the background, and it is impossible to alarm faults in real time.

[0005] In the prior art, invention patent CN105357481A proposes a multi-dimensional inspection system, which includes a monitoring center connected to a video inspection system, a drone inspection system, a robot inspection system and a manual inspection system, respectively, combining the above four systems to complement each other's advantages. However, in the face of the ever-expanding scale of the power network, the adoption of the above solution requires high equipment costs and the subsequent inspection equipment maintenance costs.

[0022] Obviously, many modifications and changes made by those skilled in the art based on the purpose of the present invention belong to the protection scope of the present invention.

[0023] It will be understood by those skilled in the art that, unless expressly stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present invention refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0025] The embodiment of the present invention provides a power monitoring network security intelligent inspection system. Figure 1 , Figure 1 A schematic diagram of the structure of an intelligent inspection system for power monitoring network security provided by an embodiment of the present invention, the system includes a data acquisition unit, a data transmission verification unit, a data transmission unit, an alarm and response unit, an electrical fire monitoring unit, a power status monitoring unit, a human-computer interaction unit and a central processing unit, wherein the data acquisition unit is connected to the central processing unit via the data transmission unit, and the remaining units are directly connected to the central processing unit; Optionally, the electrical fire monitoring unit includes an electrical fire monitoring host and an electrical fire monitoring module in each regional power transmission and distribution equipment box connected to it, which is used to detect parameters such as residual current and fault arc in the electrical circuit of the power equipment; the power supply status monitoring unit includes a power supply status monitoring host and a power supply status monitoring module in each regional power equipment connected to it, which is used to detect parameters such as voltage, current, power and frequency related to the power equipment.

[0026] The electrical fire monitoring host and the power status monitoring host are usually installed in the fire control room. When the inspection system of the existing power monitoring network is modified, the central processing unit can directly obtain the corresponding electrical operation parameters through the above-mentioned monitoring host.

[0027] Optionally, the sensor unit includes a sensor module for collecting signals, which may be a temperature and humidity sensor, a fire alarm sensor, a water immersion sensor, an intrusion alarm sensor, etc. The data of the sensor module may be transmitted to the central processing unit via wired or wireless means.

[0028] Optionally, the central processing unit can set different inspection cycles according to the importance level of the power equipment, and then use different sampling frequencies for different power equipment. For example, for the regional power distribution box, the data collection cycle is set to 1 hour each time, the secondary distribution box data collection cycle is set to 3 hours each time, and the tertiary distribution box data collection cycle is set to 6 hours each time. The above sampling cycle setting method can be flexibly adjusted according to the inspection requirements and the historical fault data of the power equipment, and is not specifically limited here.

[0029] Optionally, the data transmission verification unit is synchronously set based on the above-mentioned different sampling periods. Before each sampling, the data transmission verification unit sends verification data. When the central processing unit receives the verification data, it determines that the data transmission in the area is normal and performs data collection. If the verification data is not received, it is determined that a network transmission failure has occurred in the data collection in the area, and an alarm signal is output and a professional maintenance personnel is dispatched for maintenance. Specifically, the verification data sent by the data verification unit is a heartbeat signal with the location of the power system equipment or the set inspection period. The data verification unit processes the verification data and sends it to the central processing unit. Specifically: Out_put = In_put * (In_put + 1), Input_put is the verification data sent, and Output_put is the data sent to the central processing unit. The central processing unit compares the received data with the Output_put data. If they are consistent, the data transmission is normal. If they are inconsistent, a data transmission failure occurs and a signal is sent to the alarm and response unit.

[0030] Specifically, the data transmission unit can also serve as a data verification unit, which processes and calculates the set verification data and then sends it to the central processing unit to verify the reliability of data transmission and processing.

[0031] Optional, for data acquisition unit, please refer to Figure 2 The data preprocessing module processes the signals output by the electrical fire monitoring module, the power supply monitoring module and the sensor module, and the data acquisition module acquires the signal data processed by the data preprocessing module.

[0032] The data preprocessing module includes a signal input module, a switch selection module, a clock module and a display module. Figure 3 The signals of the electrical fire monitoring module, power supply monitoring module and sensor module are connected in parallel to the signal input module. The above three modules have three different types of input signals, representing the normal, abnormal and faulty operating states. Among the three signals, the fault state has the highest priority, the abnormal state is second, and the normal state has the lowest priority. The signal input module determines the input signal state and priority. If any signal has a fault state, the output end of the signal input module outputs a fault signal to the switch selection module. If there is no fault state, the abnormal state is determined. If there is no abnormal state, the normal operation signal of the device is output.

[0033] The switch selection module is divided into three output circuits corresponding to the normal, abnormal and fault states of the input signal. Circuit L1 represents the normal operation state of the equipment, circuit L2 represents the abnormal operation state of the equipment, and circuit L3 represents the fault operation state of the equipment. Different operation states can be displayed by indicator lights of different colors set on the outside of the power equipment box. Specifically, Figure 4 As shown, signal light b is a yellow indicator light, representing an abnormal operating state, and signal light c is a red indicator light, representing a faulty operating state.

[0034] The output loop L1 of the switch selection module is connected to the normal operating status signal indicator light a through the timing clock module. The number of indicator lights a can be one or more. For example, a corresponding number of indicator lights a1-an are set according to the number of inspections per day or per week. When the data acquisition module collects the equipment operating status signal, different inspection time periods correspond to different indicator lights. By collecting different signals, it also has the function of data transmission status verification. In addition, it can also determine whether there is an abnormality in the data preprocessing module within different inspection cycles.

[0035] Optionally, the data acquisition module collects the signal light signal in the output loop of the data preprocessing module. The specific data acquisition module can adopt an intelligent camera with both data transmission and data processing functions. The operating status of the equipment can be directly judged by the type of indicator light. If the power equipment is in normal operation, only the normal operation results of the equipment need to be sent to the central processing unit during the inspection set period, thereby reducing the data transmission volume of the central processing unit and the amount of calculation in the data processing process.

[0036] In another embodiment, the data acquisition module is a camera that has been installed on site or is a conventional model of the power equipment, which records the power equipment on site in real time and saves it locally. At the set time of the inspection cycle, the captured image data is sent to the central processing unit via the data transmission unit, and the central processing unit determines the operating status of the equipment. Compared with the above-mentioned smart camera, the real-time performance of the power equipment fault judgment in this embodiment is reduced, but the monitoring equipment in the existing power monitoring network can be used, and the modification cost is low.

[0037] Optionally, the alarm and response unit issues an alarm based on abnormal operation or fault status of the power equipment, and simultaneously dispatches an order based on the priority of the power equipment fault. Specifically, the alarm uses an audible and visual alarm to warn irrelevant personnel not to approach and facilitate maintenance personnel to promptly identify the equipment fault area for maintenance. The alarm and response unit can also send information to the maintenance personnel's mobile phone, or remind them through a mobile APP.

[0038] Optionally, the human-computer interaction unit displays the equipment operation status information through the display screen. When an abnormality or fault occurs in the power equipment, the fault information is displayed in a pop-up window or a warning sound is issued to remind the on-duty personnel. In addition, the on-duty personnel can also actively retrieve the real-time monitoring information of the power equipment in the target area through the human-computer interaction unit, so as to fully understand the operation status of the power monitoring network.

[0039] Optionally, the central processing unit stores and statistically analyzes the fault information of the power equipment, and flexibly adjusts the inspection cycle of the power equipment in the corresponding area according to the fault frequency of the power equipment, which can reduce the amount of data received and processed by the central processing unit, thereby reducing the hardware requirements of the central processing unit.

[0040] On the other hand, the central processing unit can also directly obtain the operating status information of the power equipment from the electrical fire monitoring unit, the power status monitoring unit and the sensor unit. When an abnormality or failure occurs, the data acquisition unit data can be compared and analyzed with the above-mentioned fault results, and further judgment can be made by retrieving real-time monitoring images, thereby improving the accuracy of the inspection results and reducing false alarms. Embodiment 2

[0041] The embodiment of the present invention also provides a method for intelligent inspection of network security based on power monitoring. Figure 5 , Figure 5 A flow chart of a method for intelligent inspection of power monitoring network security provided by an embodiment of the present invention, the method comprising the steps of: S1. Collect the operating parameters of the power equipment through the electrical fire monitoring module, the power status monitoring module and the sensor module; Optionally, the step S1 includes: An electrical fire monitoring module is used to detect parameters such as residual current and fault arc in the electrical circuit of the power equipment; a power status monitoring module is used to detect parameters such as voltage, current, power and frequency related to the power equipment; a sensor module may specifically be a temperature and humidity sensor, a fire alarm sensor, a water immersion sensor, an intrusion alarm sensor, etc., and the data of the sensor module may be transmitted to the central processing unit via wired or wireless means; S2. Preprocess the collected operating parameters of the power equipment and output the operating status information of the power equipment; Optionally, step S2 includes: The signals of the electrical fire monitoring module, power supply monitoring module and sensor module are connected in parallel to the signal input module. The above three modules have three different types of input signals, representing the normal, abnormal and faulty operating states. Among the three signals, the fault state has the highest priority, the abnormal state is second, and the normal state has the lowest priority. The signal input module determines the input signal state and priority. If any signal has a fault state, the output end of the signal input module outputs a fault signal. If there is no fault state, an abnormal state determination is performed. If there is no abnormal state, the normal operation signal of the equipment is output. Corresponding to the normal, abnormal and fault states of the input signal, there are three output circuits. Circuit L1 represents the normal operating state of the equipment, circuit L2 represents the abnormal operating state of the equipment, and circuit L3 represents the faulty operating state of the equipment. Different operating states can be displayed by indicator lights of different colors set on the outside of the power equipment box. Signal light b is a yellow indicator light, representing an abnormal operating state, and signal light c is a red indicator light, representing a faulty operating state.

[0042] S3. Verify the data transmission of the power monitoring network, including: Different inspection cycles are set according to the importance level of the power equipment, and different sampling frequencies are adopted for different power equipment. For example, for the regional power distribution box, the data collection cycle is set to 1 hour, the data collection cycle of the secondary distribution box is 3 hours, and the data collection cycle of the tertiary distribution box is 6 hours. The above sampling cycle setting method can be flexibly adjusted according to the inspection requirements and the historical fault data of the power equipment.

[0043] Based on the above different sampling cycles, synchronization settings are performed. Before each sampling, verification data is sent. If the central processing unit does not receive the verification data, it is determined that a network transmission failure has occurred in the data collection in this area, and an alarm signal is output and professional maintenance personnel are dispatched for maintenance. If the verification data is received, the collected data is transmitted.

[0044] If the result of step S3 is that the data transmission is normal, proceed to step S4.

[0045] S4. Collecting operation status information pictures of power equipment and sending them to the central processing unit, including: To collect the operating status signal light signals of power equipment, an intelligent camera with both data transmission and data processing functions can be used. The operating status of the equipment can be directly judged by the type of indicator light. If the power equipment is in normal operating status, only the normal operation results of the equipment need to be sent to the central processing unit during the inspection set period, thereby reducing the data transmission volume of the central processing unit and the amount of calculation in the data processing process.

[0046] On the other hand, it is also possible to use cameras that have been installed on site or conventional models of power equipment to record the power equipment in real time and save it locally. At the set time of the inspection cycle, the captured image data is sent to the central processing unit via the data transmission unit, and the central processing unit determines the operating status of the equipment. Compared with the above-mentioned smart camera, the real-time performance of the power equipment fault judgment in this embodiment is reduced, but the monitoring equipment in the existing power monitoring network can be used, and the modification cost is low.

[0047] S5. Verify the operating status information of the power equipment to determine whether there is a fault or false alarm, including: The central processing unit can also directly obtain the operating status information of the power equipment from the electrical fire monitoring unit, the power status monitoring unit and the sensor unit. When an abnormality or fault occurs, the data from the data acquisition unit can be compared with the operating status information of the power equipment collected in step S4, and further judgment can be made by retrieving the real-time monitoring image. If it is determined to be an abnormal or faulty state, an alarm signal is output and a maintenance order is issued. If it is determined to be a false alarm, no alarm signal is output.

[0048] S6. Fault or abnormal alarm, and maintenance dispatch.
