At this time, the main control unit sends out a high-level control signal to the gate of the field effect transistor Q1 through the resistor R5. During normal communication, the field effect transistor Q3 is also conducted, at the moment, the drain electrode of the field effect transistor Q3 outputs a low-level signal to the main control unit, and at the moment, the two communication connection lines 3 are indicated to normally communicate.
