[0027] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a system for monitoring faults of overhead power equipment is provided.

[0028] Specifically, Figure 1 As shown, the overhead power equipment fault monitoring system includes a fault monitoring module, a fault processing module and a fault alarm module. The fault monitoring module is arranged on the overhead power equipment. The fault monitoring module is used to monitor fault signals and generate monitoring data; the fault processing module is electrically connected to the fault monitoring module; the fault alarm module communicates with the fault processing module; wherein the fault processing module is used to generate a control instruction set based on the monitoring data, and the control instruction set is used to control the fault alarm module to generate a fault alarm signal.

[0029] Applying the technical solution of this embodiment, the overhead power equipment fault monitoring system includes a fault monitoring module, a fault processing module and a fault alarm module. The fault monitoring module is arranged on the overhead power equipment. The fault monitoring module is used to monitor fault signals and generate monitoring data; the fault processing module is electrically connected to the fault monitoring module; the fault alarm module communicates with the fault processing module; wherein the fault processing module is used to generate a control instruction set based on the monitoring data, and the control instruction set is used to control the fault alarm module to generate a fault alarm signal. The fault monitoring module can monitor the operating status of the overhead power equipment in real time and generate monitoring data in real time. When the monitored data is abnormal, the abnormal data is sent to the fault processing module to start the fault processing process. The fault processing module generates a control instruction set, and controls the fault alarm module to generate a fault alarm signal to promptly notify the staff to take effective measures to prevent power interruption and ensure the stable operation of the power grid. Through the characteristics of real-time monitoring and rapid response, the fault monitoring system can significantly reduce the fault time of the power equipment and reduce the economic losses caused by power interruption. For example, during the peak period of electricity consumption, or when lightning strikes, discharges and other events occur, once the power equipment fails, the fault monitoring system can immediately respond to notify the staff to avoid large-scale power outages.

[0030] Specifically, Figure 2 As shown in the figure, the fault monitoring module includes an electromagnetic field sensor, a photoelectric sensor and an acoustic sensor. The electromagnetic field sensor is used to monitor the electromagnetic pulse signal in the fault signal; the photoelectric sensor is used to monitor the photoelectric signal in the fault signal; and the acoustic sensor is used to monitor the acoustic wave signal in the fault signal. Through the combined use of electromagnetic field sensors, photoelectric sensors and acoustic sensors, the fault monitoring system can capture and monitor abnormal signals from multiple aspects, such as arc discharge, overheating of overhead power equipment transmission lines, abnormal mechanical vibration and other signals, which is suitable for multi-type fault monitoring and improves the accuracy and comprehensiveness of fault identification. In one event, multiple sensors such as electromagnetic field sensors, photoelectric sensors and acoustic sensors can simultaneously monitor abnormal signals, identify faults more quickly and accurately, reduce the probability of false alarms and missed alarms, and improve the safety of power system operation.

[0031] Furthermore, the overhead power equipment fault monitoring system also includes a communication module, through which the fault monitoring module communicates with the fault location module, and through which the fault location module communicates with the fault processing module; wherein the communication module includes at least one of a wireless communication module and a wired communication module. The setting of the communication module ensures the rapid transmission of signals between the fault monitoring module and the fault location module, and between the fault location module and the fault processing module. At the same time, the communication module can also transmit the signal and fault information back to the control center in a timely manner. The staff can understand the fault situation of the overhead power equipment by monitoring the signal of the control center, avoiding the traditional inspection method of walking along the line to inspect the overhead power equipment, which can reduce the labor intensity and improve the efficiency of fault monitoring.

[0032] In one embodiment of the present application, wireless communication can adopt wireless communication technologies such as 4G / 5G modules, LoRa, ZigBee or NB-IoT to transmit monitoring data to a remote control center in real time. When necessary, wireless communication and wired communication can be combined to transmit data and signals. Wired communication is used in scenarios where high signal transmission stability is required. For example, when there are dense wires in overhead power equipment and strong electromagnetic interference may be generated, wired communication is combined to communicate between the fault monitoring module, the fault location module and the fault processing module. Optionally, wired communication can be carried out by optical fiber or other means.

[0033] Specifically, the overhead power equipment fault monitoring system also includes a power management module, which is used to manage the system power supply, and the system power supply is used to supply power to at least one of the fault monitoring module, the fault alarm module, the fault processing module, and the communication module. By setting the power management module, the electrical signals and power consumption of the fault monitoring module, the fault alarm module, the fault processing module, and the communication module are managed, and power is supplied to them at the same time to ensure that each module can operate normally.

[0034] It should be noted that the power management module includes a power supply battery and a backup battery to ensure the normal operation of the fault monitoring system. Since overhead power equipment will be set up in various environments in real life, and most of them will be installed in remote or high places, priority is given to using renewable power systems to power the fault monitoring system. For example, through renewable energy such as solar panels or wind turbines, the fault monitoring system can be powered stably for a long time to ensure the stable operation of the fault monitoring system, reduce manual maintenance costs and operating costs. At the same time, the setting of the backup battery can further ensure that the fault monitoring system can operate normally at night or in bad weather, thereby improving system reliability.

[0035] Furthermore, electromagnetic field sensors are arranged on the top of the substation and the top of the tower of the overhead power equipment. Photoelectric sensors are arranged on the high-voltage lines of the overhead power equipment. Acoustic sensors are arranged on the transmission lines of the overhead power equipment. Placing electromagnetic field sensors on the top of the substation or the top of the tower of the overhead power equipment can effectively monitor the changes in the electromagnetic environment around the substation and the tower, and can promptly detect the occurrence of faults such as transformer overload and insulator flashover; arranging photoelectric sensors on the high-voltage lines of the overhead power equipment can monitor overheating, arcing and other phenomena in the lines, and can effectively prevent accidents such as short circuit or fire of the high-voltage lines; arranging acoustic sensors on the transmission lines of the overhead power equipment can monitor the mechanical vibration and abnormal noise of the lines, such as insulator damage, wire wear and the like. The arrangement of electromagnetic field sensors, photoelectric sensors and acoustic sensors in the above positions can improve the safety of power system operation.

[0036] It should be noted that the effective coverage distance of electromagnetic field sensors, photoelectric sensors and acoustic sensors is limited, and the sensitivity of each sensor is not uniform and the working environment requirements of each sensor are different. Therefore, the number and location of each sensor can be considered according to the actual specific situation. For example, in areas with dense high-voltage lines, multiple photoelectric sensors can be set at key line nodes and multiple acoustic sensors can be deployed at key parts of the equipment. In addition, the entire fault monitoring system also adopts a distributed architecture distributed throughout the power equipment network to form a distributed monitoring network. Each sensor can cover a larger area to improve the fault location accuracy and improve the monitoring accuracy and reliability of the fault monitoring system.

[0037] Furthermore, the fault processing module includes a data acquisition module, a data processing module and a signal generation module. The data acquisition module is used to collect monitoring data, and the monitoring data at least includes signal type information and signal location information of the fault signal; the data processing module is used to identify the fault information of the overhead power system based on the monitoring data, and the fault information at least includes fault type information and fault location information; the signal generation module is used to generate a control instruction set based on the fault information. The modularization of data acquisition and data processing makes fault processing more efficient, and the fault point can be quickly located, reducing the impact of the fault on the power supply.

[0038] In one embodiment of the present application, the fault processing module can use a microcontroller MicrocontrollerUnilt (MCU), a field-programmable gate array Field-Programmable Gate Array (FPGA), and a processor based on an ARM (Advanced RISC Machine) architecture to collect data from each sensor in real time and perform preliminary processing. Preferably, the controller uses a low-power microcontroller (such as the STM32 series); the data processing module in the fault acquisition module integrates data from different sensors, filters noise, and identifies the characteristics of lightning strikes and discharge events to analyze the specific type and location of the fault. The signal generation module generates a control instruction set, and the control instruction set activates a fault alarm.

[0039] Specifically, Figure 3 As shown in the figure, the fault processing module also includes a local storage module and a data upload module. The local storage module is used to store fault information locally; the data upload module is used to upload fault information to the cloud. The dual storage mechanism of local storage and cloud upload ensures the security of fault information. Even if the local storage module fails, data can be restored from the cloud. It is suitable for long-term storage and remote analysis of power equipment fault information, providing data support for fault prediction and preventive maintenance of the power system, reducing the maintenance cost of power equipment and the risk of power outages.

[0040] Furthermore, if Figure 4 As shown, the fault alarm module includes a local alarm module and a remote alarm module. The local alarm module is used to generate a local alarm signal, which includes at least an audible and visual alarm signal; the remote alarm module is used to generate a remote alarm notification, which includes at least a text message alarm notification and an email alarm notification. The local alarm module reminds the on-site personnel through the audible and visual alarm signal, and the remote alarm module notifies the remote control center of the fault information through text messages, emails, etc. The dual alarm form of the local alarm module and the remote alarm module can ensure that the fault information can be received and processed in time, that is, the on-site staff and the staff of the remote control center can receive the fault alarm in the first time, and the remote and on-site linkage comprehensive processing of events can be realized to avoid failures in the operation of the power system.

[0041] The present application also provides a circuit board of a fault monitoring system and a circuit board design method, the design method includes multiple steps and principles, specifically including hardware design, schematic drawing, PBC motherboard layout, power management, and communication interface design.

[0042] Specifically, the fault monitoring system is divided into a fault monitoring module, which includes an electromagnetic field sensor, a photoelectric sensor, an acoustic sensor, etc.; a data processing module, which includes a core processing unit for collecting and processing sensor data; a power management module, which is used to manage the charging and voltage regulation of the solar power supply and the backup power supply; a communication module, which is responsible for the wired or wireless transmission of data and signals; and an interface module, which is connected to external overhead power equipment or used for debugging, such as UART, SPI, I2C and other interfaces.

[0043] Select appropriate components according to functional requirements, such as STM32 MCU microcontroller, LoRa communication module, photodiode, solar charging controller, etc. in this embodiment; use EDA software (such as Altium Designer, KiCAD, Eagle) to draw circuit schematics, ensure that the connections between modules are correct, and add necessary filter capacitors, protection diodes and other components; design voltage stabilization circuits to ensure that the operating voltage of each module is stable, and consider using low-power components, especially sensor modules and communication modules; design debugging interfaces for MCU or FPGA to facilitate firmware development and system debugging.

[0044] Determine the PCB layout, usually using a double-layer or four-layer PCB to facilitate wiring and ground processing, place key components in appropriate locations, pay attention to the layout of sensor input ports and communication antennas to reduce interference, perform PCB wiring according to the schematic diagram, pay attention to signal integrity and power ground processing, keep high-frequency signal routing as short as possible and use appropriate impedance control; consider heat dissipation requirements and the physical installation location of the equipment, and design holes and housings; reduce electromagnetic interference through appropriate shielding and wiring strategies.

[0045] After the circuit layout is completed, use simulation tools (such as SPICE, Altium simulation module) to simulate the power supply and signal link to ensure the stability and reliability of the design, and analyze the integrity of high-speed signal transmission to prevent reflection or crosstalk problems.

[0046] Electrical testing is carried out after the PCB is manufactured to ensure that the equipment has no short circuit or open circuit problems. System integration and testing are then carried out. Each sensor input is tested, and the working condition of the power management module is checked to ensure the normal operation of each module. The firmware is written and debugged to test the data acquisition, processing, communication and other functions of each sensor. All modules are integrated together to test the overall function and performance of the system under laboratory and field conditions. Finally, lightning strikes and discharge faults are simulated in the actual power environment to verify the system's response and monitoring accuracy.

[0047] From the above description, it can be seen that the above embodiments of the present invention can monitor the operating status of overhead power equipment in all directions and from multiple angles by integrating multiple sensors and processing modules, timely and accurately identify the fault type and location, effectively improve the operating safety and maintenance efficiency of the power system, and have the following beneficial effects:

[0048] 1) The system uses wireless and wired communication modules to ensure the stability and real-time performance of data transmission. The power management module ensures the continuous operation of the system, and it can work stably even in remote or harsh environments.
