Description

TECHNICAL FIELD

[0001] The present application relates to the field of environmental simulation control, in particular to a safety protection system for a high-altitude environmental test chamber. BACKGROUND

[0002] The environmental characteristics of plateau areas are: low atmospheric pressure, small air density, low temperature, large diurnal temperature difference, strong sunlight (ultraviolet light), large wind and sand, complex terrain, and poor road conditions. Vehicles used in plateau areas are affected by natural environmental conditions and long-term effects, and the functions, performance and reliability of the vehicles are all affected to varying degrees, and in severe cases, the vehicle functions can fail. Currently, in order to improve the adaptability and reliability of products, various altitude working conditions are tested before the products are shipped. Vehicles used in plateau areas must be subjected to high-altitude environmental adaptability tests to verify their adaptability to the plateau environment during storage, transportation and use in plateau areas. In order to save product development and testing time and reduce testing costs, many altitude environmental simulation test chambers have been established.

[0003] The human body is not greatly affected in an environment below an altitude of 3000m, and in this case, although the slight decrease in oxygen partial pressure can be compensated for by increasing respiration and heart rate. In particular, above an altitude of 3000m, the human body needs a gradual adaptation process. The higher the altitude, the longer the time spent in altitude testing, and the lower the altitude simulation rate required to reach the altitude environment. Therefore, the safety of personnel at high altitudes and during altitude transitions must be ensured. SUMMARY

[0004] A series of simplified concepts are introduced in the summary section, which are simplifications of the prior art in the field, which will be described in further detail in the detailed description section. The summary section of the present application does not mean to attempt to limit the key features and necessary technical features of the claimed technical solution, nor does it attempt to determine the protection scope of the claimed technical solution.

[0005] The technical problem to be solved by the present application is to provide a high-altitude environmental test chamber safety protection system that allows personnel to safely enter and exit a high-altitude test chamber for various operations, ensuring the health and safety of operating personnel.

That is, the first pipeline can be connected to the external environment, or connected to the passage control room, because the pressure of the control room and the external environment is consistent.

[0022] Optionally, the high altitude environment laboratory safety protection system is further improved, the first control assembly comprises:

[0023] a first emergency manual operation valve connected to the first pipeline;

[0024] a first emergency rescue operation valve connected to the first pipeline;

[0038] Optionally, further improve the high-altitude environment laboratory safety protection system, and the high-altitude environment laboratory safety protection system further comprises:

[0039] The second silencer is formed at one end of the second pipeline in the high-altitude environment laboratory.

[0040] Optionally, further improve the high-altitude environment laboratory safety protection system, and a display screen is arranged in the transition chamber, which is used for displaying the collected values of the pressure sensors in real time and outputting control signals (electric signals) through the operation screen to control the operation valves and then control the pressures in the control chamber, the transition chamber and the high-altitude environment laboratory.

[0041] The high-altitude environment laboratory safety protection system of the application provides the following three working modes:

[0042] Mode one: normal automatic operation mode of the altitude transition chamber

[0043] Case one: when a person needs to enter the altitude test chamber, the first transition door on the control chamber side is first pressed to apply for opening the first transition door, and the safety protection system of the application is operated by judging the current pressure in the altitude transition chamber. When the first pressure difference sensor measures the value within the set first pressure difference range (preferably, the first pressure difference sensor collects the pressure difference of zero), the first transition door is allowed to be opened; when the pressure difference between the altitude transition chamber and the control chamber exceeds the first pressure difference range, the first pipeline is first controlled to open the remote three-way electric valve to perform pressure balance operation. Until the pressure difference between the two is within the first pressure difference range (preferably, the first pressure difference sensor collects the pressure difference of zero), the first transition door is opened.

[0044] When the person enters the altitude transition chamber, the transition chamber side button of the second transition door is pressed to apply for opening the second transition door. At this time, the safety protection system balances the pressure between the test chamber and the altitude transition chamber through the second pipeline, and when the second pressure difference sensor measures the value within the set second pressure difference range (preferably, the second pressure difference sensor collects the pressure difference of zero), the second transition door is allowed to be opened, and the person safely enters the test chamber.

[0045] Case two: when the personnel need to exit the altitude test chamber, first press the button on the test chamber side of the second transition door to apply for opening the second transition door, and the safety protection system operates by judging the current pressure in the altitude transition chamber. When the second differential pressure sensor measurement value is within the set second pressure difference range (preferably the second differential pressure sensor collects a pressure difference of zero), the second transition door is allowed to be opened; when the pressure difference between the altitude transition chamber and the control chamber exceeds the second pressure difference range, first control the remote three-way electric valve to open the second pipeline for pressure balance operation. Until the pressure difference is within the second pressure difference range (preferably the second differential pressure sensor collects a pressure difference of zero), the second transition door can be opened.

[0046] When the personnel enter the altitude transition chamber, the first transition door side button on the transition chamber is pressed to apply for opening the first transition door. At this time, the safety protection system controls the pressure balance between the control chamber and the altitude transition chamber through the first pipeline. When the first differential pressure sensor measurement value is within the set first pressure difference range (preferably the first differential pressure sensor collects a pressure difference of zero), the first transition door can be opened; the personnel safely exit the test chamber.

[0047] Mode two: emergency manual operation mode of the altitude transition chamber

[0048] When the test chamber has equipment failure or altitude out-of-control, all pipelines in the test chamber that communicate with the outside world will be cut off. At this time, personnel need to manually balance the pressure of each room through the emergency manual operation valves of the first pipeline, the second pipeline, the third pipeline and the fourth pipeline.

[0049] Mode three: emergency rescue operation mode of the altitude transition chamber

[0050] When the personnel need emergency rescue, the rescue personnel can manually balance the pressure of each room through the emergency rescue operation valves of the first pipeline, the second pipeline, the third pipeline and the fourth pipeline. The emergency rescue valve has a larger air flow area than the emergency manual operation method, so that the altitude control rate is faster and the time required to balance each room is shorter.

[0051] The above technical solutions can avoid the health risks of operating personnel entering and exiting the high-altitude (3000m and above) environment test chamber, and ensure the health and safety of the operating personnel. BRIEF DESCRIPTION OF DRAWINGS
