| description | The invention relates to a startup and shutdown control method and a control circuit, and the method comprises the steps that two sensor probes are short-circuited for a preset time, and a short-circuit signal is generated; the voltage follower generates a 0 V voltage to ground according to the short circuit signal and outputs the voltage to ground to the latch; the latch outputs a low level to the switch tube according to the voltage to ground; and the switch tube conducts power supply according to the low level so as to realize startup. According to the invention, the startup and shutdown control is relatively simple, the startup can be realized only after the sensor probe is installed during startup, and the shutdown can be realized only after the monitoring center sends a remote shutdown instruction to the microprocessor during shutdown.
本发明涉及一种开关机控制方法和控制电路，该开关机控制方法包括开机步骤包括：将两根传感器探针短路预设时间，产生短路信号；电压跟随器根据所述短路信号产生0V的对地电压，并将所述对地电压输出到锁存器；锁存器根据所述对地电压输出低电平到开关管；所述开关管根据所述低电平导通电源供应，从而实现开机。本发明开关机控制相对比较简单，在开机时，只能在传感器 |
