Intelligent door of locomotive

Abstract

The invention provides an intelligent door of a locomotive. The intelligent door comprises a door, a display alarm box and an electromagnetic lock arranged on the door, the display alarm box comprisesa control host and a display slave, the control host comprises a microprocessor minimum system, a signal acquisition module and an external driving circuit, the external driving circuit controls theon-off of the power supply of the electromagnetic lock, and the signal acquisition module is connected with a speed sensor arranged on a main shaft of the locomotive and a position sensor arranged ina lock hole of the electromagnetic lock. When the locomotive speed exceeds a safety threshold value, the electromagnetic lock is powered on to achieve locking of the door, meanwhile, whether the dooris normally closed or not is judged by detecting whether a spring bolt stretches out in place or not, the display slave communicates with the control host, current vehicle speed information, door state and fault conditions are fed back on the display screen in real time, and the display alarm boxes communicating with one another are arranged in driver's rooms at the two ends of the locomotive. Theintelligent door is high in intelligent degree, can guarantee the safety of drivers and passengers, and achieves the synchronization of the opening and closing state information of doors at two endsof the locomotive.

Description

Technical field [0001] The invention belongs to the technical field of rail vehicles, and particularly relates to a locomotive smart door. Background technique [0002] Traditional locomotive cab entrances and exits use simple mechanical locks to close the doors. The degree of intelligence is not high during use. Not only is it possible to forget to close the doors due to human negligence, but also after a long period of use. The situation where the door cannot be locked and fixed due to the wear of the mechanical lock, causing personal injury to the drivers and passengers during the high-speed running of the locomotive. [0003] In addition, both ends of the locomotive are equipped with driver’s cabs, but because there is usually only the driver’s cab located in the direction of travel during driving, the operator in the driver’s cab at one end cannot know the closing of the door in the cab at the other end in time. It is often necessary to send people across the entire carriage ...

AI Technical Summary

Problems solved by technology

[0002] The traditional locomotive driver's cab uses a simple mechanical lock to close the door. During use, the degree of intelligence is not high. Not only may the door be forgotten due to human negligence, but also after a long period of use, Due to the wear and tear of the mechanical lock, the door cannot be locked and fixed, causing personal injury to the driver and passengers during the high-speed driving of the locomotive

[0003] In addition, there are cabs at both ends of the locomotive, but since only the cab in the direction of travel is usually occupied during driving, the operator in the cab at one end cannot know the closing status of the door in the cab at the other end in time. It is often necessary to send people through the entire carriage to check and verify, which not only wastes manpower, but also cannot achieve real-time feedback
