Abstract

The invention belongs to the field of stepping motor detection, in particular to an automobile stepping motor detection system. In view of the problems that the existing detection system has a singlefunction, on one hand, less detection data are acquired, thus lacking electric leakage and temperature detection of the stepping motor, and on the other hand, heat dissipation and cooling cannot be performed on the detected motor, thus affecting the service life of the stepping motor, the following scheme is proposed: the automobile stepping motor detection system comprises a module to be detected, a signal conditioning circuit module and a virtual instrument module, the module to be detected is connected with the signal conditioning circuit module, the signal conditioning circuit module is connected with the virtual instrument module, and the module to be detected comprises a stepping motor system unit, a motor driving circuit unit, an electric leakage detection unit and a temperature detection unit. The automobile stepping motor detection system provided by the invention has a reasonable structure and convenient operation, the detection system has various functions, not only acquirescomprehensive detection data, can perform real-time detection on the temperature of the stepping motor, and can also perform heat dissipation on the stepping motor, thereby prolonging 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...
