Method for automatically eliminating accumulated ice at bottom of motor train in running process of high-speed motor train unit

Abstract

The invention relates to high-speed railway transportation, in particular to a method for automatically eliminating accumulated ice at the bottom of a motor train in the running process of a high-speed motor train unit. The method is suitable for high-speed rails and motor trains. The method can automatically eliminate accumulated ice at the bottom of the motor train in the running process of the high-speed motor train unit in cold seasons. The main function is to automatically clean up accumulated ice at the bottom of the motor train under the state of not parking or limiting speed; more importantly, it is avoided that water vapor or the like is condensing at the bottom of the motor train in the cold and accumulated ice is generated. According to the technical scheme, a temperature detection device unit detects the temperature at the bottom of the motor train, a control circuit gives instructions one by one according to the different temperature values obtained through detection, and a temperature control device unit is started and carries out temperature rise actions of different amplitudes on needed portions respectively. The running safety index of the high-speed motor train unit in winter is increased; the running speed and punctuality of the motor train are improved.

Description

technical field [0001] The present invention relates to railway transportation, to high-speed railways, to a Chinese train operation control system CTCS (Chinese Train Control System) and its onboard subsystem and ground subsystem, to ATP (Automatic Train Protection) for train overspeed protection, and to a single-chip microcomputer as the main body The invention relates to a temperature control circuit and peripheral accessories, relating to a software programming language, an electrothermal conversion material and a device, and in particular to a method for automatically eliminating ice accumulation on the underside of a high-speed train during operation. [0002] The invention is applicable to high-speed railways and bullet trains, and is also applicable to ordinary-speed passenger trains with electric locomotives as traction power. Background technique [0003] At present, the operating status of China's high-speed rail and bullet trains is like this: every cold winter p...

Problems solved by technology

[0005] In addition, in the overhaul station, when the daily maintenance and overhaul of the high-speed rail EMU is carried out every day, the current method of cleaning the ice accumulation on the bottom of the car is to beat it with a wooden stick to make it loose and fall

This method not only has low labor efficiency, but also easily causes damage to the car body.
