Passenger compartment door opening and closing control circuit and control method thereof and rail transit vehicle

Abstract

The invention discloses a passenger compartment door opening and closing control circuit and a control method thereof, and a rail transit vehicle. A first interface of a passenger compartment door controller is connected with an external switch, a second interface of the passenger compartment door controller is connected with a passenger compartment interior opening / closing door switch through a first normally closed contact of a first contactor. A power supply interface of the passenger compartment door controller is sequentially connected with a second contactor contact and a second normallyclosed contact of the first contactor. The external switch, the interior opening / closing door switch, and the second normally closed contact point of the first contactor are connected with a normal load power supply train line through the normally open contact point of the first contactor. One end of a coil of the second contactor is grounded, the other end is connected with the first interface and the second interface. The coil of the first contactor is connected to the normally open contact of the first contactor through a train activation circuit. The invention enables the driver to open the first passenger compartment door by adopting the external electric key of the car body under the condition that the train is not powered on.

Description

technical field [0001] The invention relates to the field of rail transit circuit control, in particular to a passenger compartment door opening and closing control circuit and control method, and a rail transit vehicle. Background technique [0002] In the prior art, the vehicle is equipped with a driver's compartment door, and the driver's compartment door is operated independently by the driver and the relatively independent operation of the passenger compartment door does not interfere with each other. After the driver enters the driver's cab through the driver's cab door, the passenger compartment door of the whole vehicle is opened and closed under the unified control of the driver. [0003] figure 1 Shown is the whole vehicle interface circuit diagram of a single passenger compartment door controller in the prior art. In the whole vehicle circuit, the power supply, zero speed, door permission, door opening and closing commands of all passenger compartment door contro...

AI Technical Summary

Problems solved by technology

When the train is not powered on, the first passenger compartment door cannot be opened by using the electric key outside the car body, and the driver cannot control the train to power on after entering the driver's cab through the first opened passenger compartment door, and the vehicle cannot be guaranteed to enter normal operation
