大容量电机的温度保护实现了对电机和环境温度的采集、显示，能够输出对电机的保护信号。程序调用了中断模块、模数转换模块、显示模块、报警及控制模块。当电机温度高于报警值或者温升过高时，系统输出报警信号和电机保护信号，当温升略高时，系统输出预报警信号。-Large-capacity motor temperature protection implemented on the motor and ambient temperature acquisition, display, capable of outputting the motor protection signal. Program calls the interrupt module, analog to digital conversion module, display module, alarm and control modules. When the motor temperature is higher than the alarm value or the temperature is too high, the system outputs an alarm signal and motor protection signal, when temperature is slightly higher, the system output pre-alarm signal.
