High-precision air pressure automatic measuring device

Abstract

The invention discloses a high-precision air pressure automatic measuring device. A high-resolution air pressure sensor, data acquisition and control and communication and operation monitoring circuits, and a spare battery are all arranged in an anti-corrosion, antitheft and waterproof closed machine case; the closed machine case is buried underground or placed in a closed room; the air pressure sensor is connected with the atmosphere pressure through a connecting pipe; a porous fiber material which is used for producing a mechanical wave filtering effect on the damping reduction of air flow is arranged in the connecting pipe; a microprocessor in the closed machine case is used for acquiring atmosphere pressure data, receiving instructions, transmitting data, and monitoring operation; wireless communication equipment is used for data communication; and a solar panel and a spare battery are used for supplying power to a system. The device combines mechanical and digital wave filtration technologies, eliminates the interference from atmosphere pressure fluctuation caused by non-meteorological factors in the atmosphere, fully plays the performance of the high-resolution air pressure sensor, improves the accuracy of the atmosphere pressure measurement, and facilitates the detailed study on change of a weather system.

Description

technical field [0001] The invention relates to a high-resolution air pressure sensor to realize air pressure measurement, in particular to a high-precision air pressure automatic measurement device. Background technique [0002] At present, the resolution of known air pressure sensors has reached 0.01Hpa, but the air pressure measurement resolution of ordinary automatic weather stations is only 0.1Hpa, which cannot meet the fine analysis requirements of weather systems. This is because the air pressure sensor in the air pressure measuring instrument of an ordinary automatic weather station is directly connected to the atmosphere, and has no anti-interference ability to air fluctuations caused by various non-meteorological factors. The data acquisition circuit has no filtering measures, and strong environmental conditions will affect the measurement accuracy. It has obvious influence, and cannot give full play to the measurement performance of the high-resolution air pressur...

[0002] At present, the resolution of known air pressure sensors has reached 0.01Hpa, but the air pressure measurement resolution of ordinary automatic weather stations is only 0.1Hpa, which cannot meet the fine analysis requirements of weather systems

This is because the air pressure sensor in the air pressure measuring instrument of an ordinary automatic weather station is directly connected to the atmosphere, and has no anti-interference ability to air fluctuations caused by various non-meteorological factors. The data acquisition circuit has no filtering measures, and strong environmental conditions will affect the measurement accuracy. It has a significant impact, and cannot give full play to the measurement performance of the high-resolution air pressure sensor, and cannot meet the requirements of high-precision air pressure measurement
