Embodiment Construction

[0013] figure 2 with image 3 The schematic block diagrams of using 4 sensors and 6 sensors to form a sensor group in the embodiment of the present invention are given respectively.

[0014] Such as figure 2 As shown, the barometric altitude detection device provided in the embodiment of using four sensors S to form the sensor group 4 is composed of a programmable controller 1, a computer 2, a sensor group 4, and a low pressure chamber 7, wherein the sensor group consists of 4 sensors S composition. The working process of the barometric altitude detection device is as follows: the programmable controller 1 reads the pressure value detected by each different sensor S in the pressure sensor group 4, and calculates to obtain the simulated altitude value in the low pressure cabin 7. Due to the adoption of the sensor group 4, the detection accuracy of each sensor S in the sensor group 4 is relatively high in the corresponding range, so that the detection accuracy can be achiev...

Abstract

The invention relates to an air pressure altitude detection apparatus, which comprises a programmable controller, a computer, a sensor set and a low pressure cabin. According to the present invention, the single sensor in the prior art is changed into the sensor set comprising a plurality of sensors, such that the problem that the precision can not achieve requirements when the air pressure altitude exceeds 10000 meters is effectively solved.

Description

technical field [0001] The invention relates to an air pressure detection device, which belongs to the technical field of air pressure detection. Background technique [0002] In daily scientific research and production activities, people often use the air pressure value to represent the corresponding altitude according to the natural phenomenon that the air pressure changes with the altitude. This altitude corresponding to the air pressure value is called the air pressure altitude. According to this principle, people often use different air pressure environments artificially generated to simulate different altitudes. The range of air pressure altitude simulated by current civil equipment is generally below 10,000 meters. In the air pressure altitude detection device, a single commercially available An easily available sensor with a resolution of 1 / 1000 can meet the barometric altitude detection requirements. However, when the device is used in a low-pressure chamber with a...
