Problems solved by technology

Urban rail trains often fail to stop at fixed points, and the doors and platform screen doors are not aligned, which affects the convenience of riding and the punctual operation of trains
A few days ago, some high-speed EMUs stopped at the station and completely relied on the driver to manually adjust the brake handle, which caused the excessive impulse of the train during braking, which directly affected the ride comfort.

Embodiment Construction

[0016] The specific implementation of the deceleration control system for trains to realize automatic arrival and parking of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] The deceleration control system for trains to realize automatic arrival and parking includes an acceleration sensing device, an automatic train protection system and a braking control unit. The acceleration sensing device is used to monitor the real-time acceleration of the train, and the automatic train protection system is used to monitor the real-time Speed ​​and displacement, the brake control unit receives real-time acceleration, real-time speed and real-time displacement signals, and outputs control signals after calculation to control the filling and exhausting of train brake cylinders, so as to realize the stop of the train.

[0018] See attached figure 1 , 2 , when the train needs to stop at the station, the distance S between the veh...

Abstract

The invention relates to a deceleration control system for realizing automatic arrival parking of trains. The deceleration control system comprises an acceleration sensing device arranged on a train, wherein the acceleration sensing device is used for monitoring the real-time acceleration of the train, the braking level command is combined with the real-time acceleration as well as a speed signal and a displacement signal obtained by an ATP (automatic train protection) system for monitoring the train operation to be output to a braking control unit. The signal outputted by the braking control unit is connected to an electrically controlled switching solenoid valve; the inflation and the exhaust of a braking cylinder are automatically controlled; therefore, the deceleration of the train is controlled; and the accurate arrival parking is realized.

Description

technical field [0001] The invention relates to a train deceleration control system, in particular to a deceleration control system for the train to realize automatic arrival and stop. Background technique [0002] Most high-speed trains and urban rail transit trains use computer-controlled direct electro-pneumatic braking systems. Due to the use of microcomputer control technology, the brake system makes the control of electro-pneumatic coordination, adjustment of empty and heavy vehicles, and anti-skid control easier and more precise. However, for the requirement of high-precision stopping distance, it is currently compensated by relying on the automatic train protection system (ATP) or the driver's constant correction of the braking command according to the stopping distance ahead. In most cases, this approach works. However, in some special cases, such as large fluctuations in road conditions, large changes in the friction coefficient of friction pairs at high speeds, ...
