preparing electric power supply for the train: the standby power can only work normally after the train is awakened (the driver presses the train awakening button).
Emergency power supply of the train: the train emergency power supply system is derived from a train storage battery, and the train emergency power supply normally works as long as the voltage of the train storage battery is larger than 84V.
The circuit breaker CB1-A, CB1-B, CB1-C, CB1-D, CB2-B, CB2-C, CB2-D protects the circuit breaker from closing.
Power loss delay module ELDM: the R1 relay is controlled in a delayed mode, and time is adjustable.
R1: and controlling the relay.
K1, K2, K3, K4: the emergency lighting lamp supplies power the contactor.
D1: and the diode is used for conducting the current in the forward direction and stopping the current in the reverse direction.
In this example, only the schematic diagram of the pair of a1 cars is provided, and the schematic diagram of the a2 car (the opposite head car) is symmetrical to the a1 car. The schematic diagrams of the B1 vehicle and the B2 vehicle are also symmetrical, and the schematic diagrams of the C1 vehicle and the C2 vehicle are also symmetrical, but in order to avoid confusion, the devices are indicated by different codes.
In the figure, relay coils and contactor coils such as R1 relays of A1 vehicles can only control R1 contacts of A1 vehicles and cannot control R1 contacts of A2 vehicles, and other devices are similar.
Starting time delay control:

When the train is in dormancy, the relay R1 can be controlled to lose power through the delay module ELDM (time adjustable) in a delay mode, so that the power-off time of emergency lighting is controlled, and the relay R1 is used for short-time lighting of train maintenance personnel.
