The timer circuit switches the second change-over switch and the third change-over switch to the pulse output unit for a certain period of time when the power supply is started, and enables the pulse output unit to output code pulses to the second communication line. The input/output control unit switches the first change-over switch to the first terminal for a certain period of time when the power supply is started, determines whether a code indicated by the code pulse received from the first terminal is a normal code, and cuts off power supplied from the first power supply line to the second power supply line when the code is not the normal code.
定时器电路在启动电源时将第二切换开关和第三切换开关切换到脉冲输出单元一定时间段,并使所述脉冲输出单元向第二通信线输出代码脉冲。输入输出控制单元在启动电源时将第一切换开关切换到第一端子一定时间段,判断从所述第一端子接收的所述代码脉冲所指示的代码是否为正规代码,并且在所述代码不是所述正规代码时切断从第一电源线供应到第二电源线的电力。
