Abstract

The invention belongs to the field of stepping motor detection, in particular to a stepping motor detection system for automobiles, aiming at the single function of the existing detection system, on the one hand, less detection data, lack of leakage and temperature detection of the stepping motor, and on the other hand On the one hand, the detected motor cannot be radiated and cooled, which affects the service life of the stepper motor. The following scheme is proposed now, which includes a module to be tested, a signal conditioning circuit module and a virtual instrument module. The module to be tested and the signal conditioning circuit The modules are connected, the signal conditioning circuit module is connected with the virtual instrument module, and the module to be tested includes a stepping motor system unit, a motor driving circuit unit, a leakage detection unit and a temperature detection unit. The invention has reasonable structure and convenient operation. The detection system has multiple functions, not only has comprehensive detection data, but also can detect the temperature of the stepping motor in real time, and can also dissipate heat to the stepping motor, thereby increasing the service life of the stepping motor.

Description

technical field [0001] The invention relates to the technical field of stepping motor detection, in particular to a stepping motor detection system for automobiles. Background technique [0002] The car meter is used to display the information when the car is running. It is an important interface and interface for the driver to communicate with the car. The stepping motor car meter controls the stepping motor by the electronic control unit, and drives the pointer to rotate to display and record the car driving. Relevant information in the process, compared with traditional moving magnet and moving coil movement car instruments, has small size, light weight, accurate indication, high reliability, and strong anti-interference, which has become the development of car meters in the world today. Trend, when the stepper motor is running, it is necessary to adjust the current and voltage signals of the stepper motor in real time, and collect the signal and display waveform of the s...
