Safety circuit for individual door control

Abstract

The invention discloses a safety circuit for independent control over vehicle doors. The safety circuit comprises a vehicle door control circuit and a door controller control circuit. After a vehicle door control relay CDPR, a normally-closed contact of a cab non-activated relay NCSR, a normally-closed contact of a cab activated relay CSR1 and a vehicle door control button CDPB are connected in series, one end is electrically connected to a connecting line of a storage battery and a DC 110 V power supply, and the other end is grounded. Output of the DC 110 V power supply is divided into four paths, and the four paths are connected to a door controller. By means of the safety circuit for independent control over vehicle doors, independent control over vehicle doors is achieved, a driver can get on or off a vehicle through any door in a compartment, and the function of single-driver get-off side-change operation on coupled vehicles is achieved. Besides, the safety of the circuit is fully considered in designing of the circuit, and the safety of vehicle door control is guaranteed.

Description

technical field [0001] The invention relates to the field of door control of urban rail vehicles, in particular to a safety circuit for individually controlling the doors. Background technique [0002] In urban rail transit vehicles, subway vehicles usually provide drivers with a separate driver's cab door for drivers to get on and off the car. The control of the driver's cab door is independent of the passenger compartment door. The driver opens and closes the driver's cab door through a mechanical key. As an important part of rail traffic, light rail articulated vehicles in urban rail vehicles have obvious advantages when passing through smaller plane curves. However, in order to pass through smaller plane curves, the length of light rail articulated vehicles is usually relatively short, so the driver's cab It is relatively small. It is difficult to arrange a separate driver's cab door for the driver to get on and off the car in the narrow driver's cab, so the driver can ...

AI Technical Summary

Problems solved by technology

If the driver closes all the doors before getting off the car, and then opens the door through the emergency unlock knob of a certain car door to get off the car, then the door will also have the problem of being unable to close after the driver gets off the car, and this method of opening the car door through the emergency unlock function The operation does not meet the driver's normal operating requirements
