With the rapid development of automotive electronics technology, the electrical and electronic parts of the vehicle in the proportion of more and more, its importance is also increasingly attracting attention, its quality directly affects the use of vehicle safety. In the design and assembly process of the car, the electrical part of the fault detection and diagnosis is also more and more important. The vehicle mounted thermal camera can simplify the detection process, improve the efficiency of the work at the same time and greatly improve the quality of the product.
What are the main applications of the vehicle mounted thermal camera in the automotive circuit diagnosis?
1. The car infrared camera can detect the surface temperature of the car
Current through the medium, due to the existence of a certain resistance of the medium, according to the law of conservation of energy can be known, the medium will consume a certain amount of electrical energy, while generating a certain amount of heat energy to temperature reflected.
The vehicle mounted thermal camera can diagnose whether there are abnormalities in the circuit and whether there are hidden design problems through the surface temperature characteristics of the vehicle electrical appliances. Using the obtained temperature information, engineers can improve the design of the circuit principle, improve the stability of the whole car electrical appliances, and finally improve the quality and safety of the whole car.
2. The vehicle mounted thermal camera can detect the circuit components
Automotive electrical energy supply is mainly based on DC voltage and current, and the power consumption is relatively small, but it is still possible to use the vehicle thermal camera to detect the temperature of circuit components (such as power tubes, ECU chips, etc.), circuit board temperature distribution, other system components (such as batteries, generators, DC motors, coils, fuses, etc.), the temperature of the electrical wiring harness and the temperature of each electrical contact, and use the obtained temperature The information obtained can be used to diagnose whether the relevant system is malfunctioning or abnormal.
The electrical system of a hybrid vehicle is relatively more complex because of the additional electrical drive system circuit compared to an energy-supplied vehicle. This system requires the conversion between AC and DC, the control of the inverter, the analysis of the load capacity of the motor, and the use of larger values of voltage and current and larger power consumption. The performance of all these functions is related to the surface temperature. Using the on-board thermal imaging camera, it is possible to analyze whether each function can work properly.
