through emergency switch, promptly open the train door, be applicable to emergency.
Door opening judgment and protection logic:
when the TCMS monitors and judges that a certain door is not closed and one or more passenger alarms are not reset and the train is stopped at the same time, the TCMS sends a traction prohibition instruction to the DCU to prohibit the train from moving
If the train line with the door open is not valid and the door closed train line is also not valid during opening, the door can still be opened to the final position.
If the trainline with the door open is invalid and the door closed trainline is also invalid during the opening process, the door will perform a closing action.
If the zero speed train line is not active during the opening process, the door will close immediately.
In the event that the zero speed train line is active, the doors will remain open after they are fully opened.
In the event that the zero speed train line is not active, the doors will close immediately after being fully opened.
After the door is fully opened, the EDCU will send the open door status to the TCMS through the MVB network.
Each EDCU has a maintenance operation button for maintenance and debugging. When the door closing train line is not effective, the maintenance person can open the corresponding door by operating the maintenance button, and the door opening sequence will become the door closing sequence when the maintenance button is operated again.
When the maintenance button is pressed to open the door, the EDCU will send the status to the TCMS through the MVB network.
2) Door closing function
