Train door lock detection system and method, detection device and motor vehicle

Abstract

The invention belongs to the technical field of mechanical part testing and discloses a train door lock detection system and method, a detection device and a motor vehicle. A front panel is fixed to the front end of a bottom plate through bolts, and a circuit module and a sleeve are embedded in the bottom plate. A door state indicator lamp is welded to the circuit module, a spring sleeves the sleeve, and a magnet is fixedly connected to the upper end of the sleeve. The system can sleeve the outer side of a door lock sleeve through the sleeve, and the door lock sleeve drives the magnet on the sleeve to rotate; a Hall switch in a circuit control box is capable of inducing magnetic field changes, detecting magnet position changes and judging door lock on-off states to further report signals of the door lock on-off states through a wireless transmission module in a circuit.

Description

technical field [0001] The invention belongs to the technical field of testing mechanical components, and in particular relates to a train door lock detection system and method, a detection device and a motor vehicle. Background technique [0002] At present, the commonly used existing technology in the industry is as follows: the door locks on railway trains are mainly used in various trains on the railway, but at present, the new intercity and bullet trains are integrated wired connections inside the car body to detect the state of the door, while ordinary express There is no door detection device on ordinary and express trains, and wiring transformation cannot be carried out according to railway requirements, so wireless transmission must be used. At present, most of the trains can only be manually inspected by the train crew, which increases labor costs and cannot be timely alarmed when abnormalities occur, and there is a lag. Another solution is to install a separate do...

AI Technical Summary

Problems solved by technology

[0004] (1) At present, most of the trains can only pass the manual inspection of the train staff, which increases the labor cost and cannot be promptly reported to the police when there is an abnormality, and there is a lag

[0005] (2) At present, the separate door magnetic device installed on the car door can only detect whether the door is opened or closed. If the door lock is opened abnormally but the door is not opened, it will not alarm, which has a great potential safety hazard. If the door magnetic solution is used , if the door is only closed but not locked, the system will also consider it to be in a normal state. If the train continues to run with the door unlocked, there will be a great safety hazard, such as a passenger opening the door or the train shaking Cause the door to open, it is easy to cause an accident

[0007] To solve the above problems, it is necessary to directly detect the state of the door lock. However, since the traditional train door locks are all mechanical lock bodies, the position of the lock tongue is directly detected, which is difficult to modify and complicated to construct.
