Description

technical field [0001] The invention relates to the field of aerial exploration, in particular to a real-time measurement device and method for air pressure, temperature and humidity. Background technique [0002] In airborne geophysical prospecting, when higher measurement accuracy is required, it is not only necessary to measure parameters such as the magnetic field, gravity, and electrical method necessary for geophysical prospecting, but also to simultaneously measure the environmental parameters of the geophysical prospecting measurement system, including Ambient temperature, humidity, and air pressure are used to correct geophysical survey measurements and improve the accuracy of geophysical survey surveys. [0003] At present, the measurement method of air pressure, temperature and humidity is generally serial sampling, that is, after sampling the air pressure signal, then sampling the temperature and humidity signal, and then processing the data by the single-chip mi...

Problems solved by technology

If the existing serial sampling technology is used to measure air pressure, temperature, and humidity, the obtained data will lose real-time performance; and because there is no clock and data storage inside the general air pressure, temperature, and humidity instruments, it cannot be synchronized with other measurements, and subsequent data cannot be performed deal with
