Haulage motor double-pipe air supply system and air supply pipe air supply monitoring method thereof

Abstract

The invention discloses a haulage motor double-pipe air supply system and an air supply pipe air supply monitoring method thereof. The system comprises an air source device, a main air header and an air supply pipe. The air source device comprises a compressor, a first air supply passage, a second air supply passage, a sensor, a control unit and a displayer, wherein the first air supply passage and the second air supply passage are arranged between the main air header and the air supply pipe and arranged in parallel. The drift diameter of the first air supply passage is larger than that of the second air supply passage. The first air supply passage is provided with a first control valve. The second air supply passage is provided with a second control valve. The sensor collects air supply pressure data and flow data of the air supply pipe. The control unit receives data collected by the sensor, transmits prompt or alarm information, controls opening and closing of the first control valve and the second control valve and controls work of the compressor. The displayer displays all the data collected by the sensor, the prompt or alarm information transmitted by the control unit and the working state of the compressor. Air supply pipe pressure and flow of the haulage motor double-pipe air supply system can be monitored, the working mode of the compressor is optimized, and potential safety hazards caused by air supply abnormity are avoided.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a locomotive double-pipe air supply system and a method for monitoring the air supply of the air supply pipes. Background technique [0002] At present, rail transit has become an important part of people's daily travel, and its safety performance has gradually become a hot spot of concern. [0003] In recent years, with the development of vehicle technology, a large number of air-using equipment such as pneumatic doors, air springs and toilets have been used in railway passenger vehicles. In order to adapt to the increasing air volume of vehicles, a double-pipe air supply system has emerged as the times require. , The double-pipe air supply system includes a main air joint pipe and an air supply pipe. The main air joint pipe supplies the compressed air generated by the air source system to the air supply pipe, and then the air supply pipe supplies the air to the vehicle's air equipme...

AI Technical Summary

Problems solved by technology

However, at present, all locomotives, especially passenger locomotives, lack effective monitoring and management means for the air supply pipes, and the drivers cannot know the real-time wind usage status of the vehicles. Changes are too frequent and too fast, which brings safety hazards to driving

On the other hand, due to the increase in the air supply demand of vehicles, the compressors used by passenger locomotives have a large displacement. Once the number of rear-mounted vehicles decreases, the air supply demand will decrease. If the air supply demand cannot be effectively implemented according to the air supply demand The control of the compressor is very likely to cause the working rate of the selected large displacement compressor (that is, the ratio of the working time per unit time to the unit time) to be too low and cause oil emulsification.

[0004] Therefore, how to effectively monitor the pressure and flow of the air supply pipes of the locomotive dual-pipe air supply system, so as to avoid potential safety hazards caused by abnormal air supply, is currently a technical problem to be solved by those skilled in the art
