Description

Technical Field

[0001] This utility model belongs to the field of passenger compartment door switch technology, specifically relating to a subway car door maintenance control circuit and its maintenance control device. Background Technology

[0002] During major overhauls of subway cars, after door inspections are completed, electric door opening and closing tests are required to ensure the doors are functioning correctly. A subway car consists of six carriages, each with five doors on each side (A and B). Each door has a door controller to manage opening and closing, as well as signal processing. Normally, the opening and closing of each side of the train's doors is controlled by buttons on the driver's cab console, essentially sending signals to each door controller. Under normal circumstances, subway doors are opened and closed via buttons on the driver's cab console. However, during overhauls, there is a process called a complete overhaul, where the subway is disassembled into individual carriages and de-energized. Electric door opening and closing tests require 500 and 1500 consecutive opening and closing cycles to detect any faults and ensure proper functioning. Therefore, a DC 110V power supply and an external door opening and closing control device are needed to enable electric door opening and closing.

[0003] Existing testing equipment can only operate in either automatic or manual mode. If switching between automatic and manual modes is required during testing, the equipment itself must be replaced. Furthermore, existing equipment requires simultaneous DC 110V and AC 220V connections to function properly, which not only increases the operational conditions but also complicates the testing process and adds complexity.

A 500-cycle door opening and closing test is required, using a counter to count the cycles. After 500 cycles, the door opening and closing stops, ending the operation. A manual mode is also available to allow for independent control of one side's opening and closing, and to perform checks such as verifying the anti-pinch, cut-off, and unlocking functions of each door. Besides enabling door opening and closing, it's necessary to check if the door can be opened without zero speed. A button is added to the zero-speed terminal for on / off control, making it convenient to operate and highly controllable.
