A hump remote push peak control system suitable for hxn5b high-power locomotive

Abstract

The invention discloses a hump remote control system for HXN5B high-power locomotives. The scheme enables the crew to observe the display state of the hump signal in the driver's cab through the vehicle-mounted equipment, which solves the difficulty of the existing crew to look at the hump signal, and is easy. The problem of signal confirmation error occurs; at the same time, it also solves the problem that the existing HXN5B locomotive cannot realize remote control and automatic peak pushing, and the crew must rely on manual operation to carry out the peak pushing operation, resulting in a large operating workload and high labor intensity. , can also solve the problem of low speed control accuracy in manual peak pushing operations, and improve the efficiency of peak pushing and dismantling operations by realizing automatic remote control of peak pushing; Or the problem that the speed change of the locomotive is not timely after the hook lifter at the peak changes the signal for pushing the peak.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a hump remote control system for pushing the hump of the HXN5B high-power locomotive. Background technique [0002] The wireless remote control system of the hump-pushing locomotive is a computer integrated control system. The system adopts wireless data transmission technology, passive transponder positioning technology, and locomotive traction braking control technology to realize automatic starting, forward, backward, speed regulation, and parking of the hump-pushing locomotive. Operation to ensure accurate and stable peak pushing speed. The working scope of the system is the whole push operation process from the time when the peak pushing locomotive is attached to the train train that is about to be dismantled at the arrival site, and the trial pull is carried out until the disintegration of the train is completed. Including the pre-push operation and the main push oper...

AI Technical Summary

Problems solved by technology

Since the flight attendants rely on the observed signal display to operate the locomotive, the wrong signal lookout has posed a greater safety hazard to the driver's operation

[0012] 2) Since the locomotive needs to frequently perform forward / reverse direction switching operations and acceleration and deceleration speed regulation operations during the peak pushing operation, the crew has a large workload and high labor intensity. It also requires better operating skills, and requires higher skill levels for flight attendants

At the same time, if the crew operates the locomotive at a speed higher than the signal display speed, it may lead to hook chasing, and the peak push speed is lower than the signal display speed, which will affect the efficiency of the dismantling operation

[0013] 3) Since the signal of the hump locomotive is not interlocked with the status of the locomotive pushing the hump in the existing mode, the speed change of the locomotive after the hump signal is changed is greatly affected by human factors. speed
