Circuit fault monitoring system based on Internet of Things

Abstract

The invention discloses a circuit fault monitoring system based on the Internet of Things. The system comprises an infrared test unit, a fault analysis module, a background terminal, a power supply switch module and a warning module. The infrared test unit comprises an excitation module, a thermal image acquisition module, a thermal image correction module and an imaging module. The excitation module is used for applying a power supply and a necessary excitation signal required for normal work to the tested circuit board to prepare for acquiring a visual thermal image before thermal image acquisition, and the thermal image acquisition module is used for acquiring infrared thermal radiation of a tested piece in a field of view. The system has the beneficial effects that the operation of cutting off the power supply is executed on the circuit board at the abnormal working environment temperature; therefore, the temperature of the circuit board is prevented from further rising, the problems of potential safety hazards and maintenance cost increase are solved, the circuit environment temperature condition of each device can be monitored in real time, and unified mastering and management of the circuit environment temperature of each device are realized.

Description

technical field [0001] The invention relates to a circuit fault monitoring system, in particular to a circuit fault monitoring system based on the Internet of Things, belonging to the technical field of circuit monitoring. Background technique [0002] A conductive circuit composed of metal wires and electrical and electronic components is called a circuit. Adding a power supply to the input end of the circuit causes a potential difference at the input end. When the circuit is connected, it can work. The existence of current can be tested by some instruments, such as voltage Meter or ammeter deflection, bulb lighting, etc. The simplest circuit is composed of power supply, electrical appliances, wires, switches and other components. When the circuit is turned on, it is called a circuit, and when it is disconnected, it is called an open circuit. Only through the circuit, there is current in the circuit Through, a disconnection of a certain part of the circuit is called an open...

Problems solved by technology

[0004] The purpose of the present invention is to solve the existing circuit fault monitoring system. When performing circuit fault monitoring, the monitoring method is contact type. When measuring parameters, it will inevitably affect the distribution parameters of the circuit, which cannot be used for real-time fault monitoring of high-frequency circuits. , and affects the real-time operation status of the equipment, the monitoring speed is slow and the efficiency is low. It is time-consuming and laborious to monitor the devices one by one. Fault Monitoring System
