Air purification system for high-speed rail train intelligent and control method of system

Abstract

The invention discloses an intelligent air purification system for a high-speed rail train. The system comprises a fresh air main pipe and an air return main pipe, flow regulating valves are respectively mounted on the fresh air main pipe and the air return main pipe; the tail end of the fresh air main pipe is connected with a fresh air temperature adjusting pipe and a fresh air bypass pipe. An air conditioner temperature adjusting module is installed on the fresh air temperature adjusting pipe, the fresh air bypass pipe and the air return main pipe are jointly connected to a primary air return pipe, the fresh air temperature adjusting pipe and the first air return pipe are jointly connected to a mixing cavity, a filter element is inserted into the mixing cavity, an air outlet pipe is connected to the air outlet side of the mixing cavity, and temperature sensors are installed on the primary air return pipe and the air outlet pipe respectively; the filter element comprises a frame, theframe is matched with an inserting groove in an inserted mode, a filter element body is fixed in the frame, the air inlet side and the air outlet side of the frame are each connected with a pluralityof overturning baffles through shafts, and air pressure sensors are installed on the surfaces of the overturning baffles. The defects in the prior art can be overcome, the air filter element is effectively monitored, and the replacement process is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of intelligent control of high-speed rail trains, in particular to an intelligent air purification system for high-speed rail trains and a control method thereof. Background technique [0002] With the rapid construction of my country's high-speed railway network, more and more high-speed trains have been put into use. Due to the high speed of high-speed trains, the requirements for the tightness of the compartments are high, so operations such as ventilation, purification and temperature adjustment of the air in the compartments of high-speed trains require a special air purification system to complete. The existing high-speed train air purification system has a complex structure, but it cannot effectively monitor the use status of the air filter element. The replacement of the filter element is completely controlled by the replacement cycle determined by experience, and the replacement process is likely to...
