Monitoring and control system for bottom door of railroad hopper car

Abstract

The invention discloses a monitor and control system for a bottom door of a railroad hopper car. The system includes a bottom door sensor, a central controller, a communication positioning module anda remote monitoring platform. The bottom door sensor is connected with the central controller through communication and used for detecting the open or close state of the bottom door; the central controller is connected with the bottom sensor and the communication positioning module through communication and used for receiving the open or close state information detected by the bottom door sensor,and controls the communication positioning module to obtain the real-time location information of the hopper car; the communication positioning module is used for obtaining the real-time location information of the hopper car and sends the open or close state information and the real-time location information to the remote monitoring platform; the remote monitoring platform is connected with the communication positioning module through communication and used for receiving the open or close state information and the real-time location information sent by the communication positioning module, and displays the open or close state information and the real-time location information. The monitor and control system for the bottom door of the railroad hopper car achieves intelligent real-time monitoring of the opening or closing state and the location information of the bottom door of the hopper car, the work intensity of operation personnel is thus reduced, potential safety hazards are timelydetected, and the transportation safety of the hopper car is ensured.

Description

technical field [0001] The invention belongs to the technical field of railway vehicles, and more specifically relates to a monitoring system for a bottom door of a railway hopper vehicle. Background technique [0002] The funnel car is a kind of railway freight car whose end wall is inclined inward or the end surface is a large arc. The lower part of the car body is equipped with a funnel and a bottom door. It can realize fast unloading without using dumpers and other station equipment. After careful design, the funnel car can also realize the function of loading various goods, and has certain versatility. The funnel car is mainly used to transport bulk goods such as coal, ore, and ballast. Most of them are gravity unloading, and the goods are loaded from the top. When unloading, the bottom door of the funnel is opened by manpower or wind, and the goods are automatically unloaded by their own gravity. It can be unloaded one by one, or several vehicles or trains can be unl...

AI Technical Summary

Problems solved by technology

Although the anti-misrotation device is added to improve the locking safety of the bottom door of the hopper car and prevent potential safety hazards caused by misoperation, the operator still cannot quickly understand the locking state, and personnel need to visually inspect the bottom door one by one. open and closed state, which undoubtedly increases the workload of the operators

Under the current management system, operators often have inadequate monitoring due to reasons such as short working hours and high labor intensity.

During the loading and transportation of the existing coal and stone ballast hopper trucks, accidents such as material leakage occur from time to time
