Oxygen control device for cab interior of trackless transport vehicle in high-attitude area and control method

Abstract

The invention relates to an oxygen control device for the cab interior of a trackless transport vehicle in a high-attitude area, and a control method. The oxygen control device comprises a control module and further comprises oxygen content detecting sensors, a voice reminding module, an oxygen replenishing module and a ventilation valve which are electrically connected with the control module, wherein the oxygen content detecting sensors are used for detecting the oxygen content in a cab and the oxygen content outside the cab, the voice reminding module haves a voice reminding function, the oxygen replenishing module is used for replenishing oxygen into the cab, and the ventilation valve is used for achieving communicating and separating of air in the cab and air outside the cab. The control module is used for receiving parameters of the oxygen content in the cab and parameters of the oxygen content outside the cab, selectively controlling the voice reminding control to remind a driver about the oxygen content in the cab and the oxygen content outside the cab according to the working state, controlling the oxygen replenishing module to replenish the oxygen into the cab till the oxygen content reaches a set value, and controlling the ventilation valve to be opened, so that the driver slowly adapts to the low-oxygen environment outside the cab. The oxygen content in the cab canbe adjusted, the driver can slowly adapt to the low-oxygen environment outside the cab and can be reminded about the oxygen content in the cab and the oxygen content outside the cab, and refitting isconvenient.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, and in particular relates to an oxygen control device and a control method in a cab of a trackless transport vehicle in a high-altitude area. Background technique [0002] Under normal circumstances, the oxygen content in the air at sea level (0 meters above sea level) accounts for about 21%. As the altitude increases, the atmospheric pressure becomes smaller and the air becomes thinner. "Monitoring and Analysis of Altitude Reactions of Passengers in Trains" shows that for every 1000 meters above sea level, the oxygen content in the air decreases by 10%. In "Monitoring and Analysis of Altitude Reactions of Passengers in the Qinghai-Tibet Train", it is shown that at an altitude of 5,000 meters, the oxygen in the air is only about 57% of that at sea level. In high-cold and high-altitude areas (over 1,500 meters above sea level), the oxygen content in the air is much lower than normal. Working in...

AI Technical Summary

Problems solved by technology

Therefore, in high-altitude areas, trackless transport vehicles (including working vehicles, heavy-duty trucks, transport vehicles, commuter vehicles, etc.) ) drivers work in a low-oxygen environment for a long time, their body functions are more likely to decline, and it is more likely to cause traffic accidents
