The invention discloses a high-altitude flat-plate-type meteorological parameter measuring system and method. The system comprises a circuit board and a wind speed and wind direction detecting module,an ambient temperature detecting module, a gas pressure detecting module, a circuit temperature control module and a main control unit which are arranged on the circuit board; the wind speed and winddirection detecting module comprises a resistance temperature sensor, a first heating device and a resistance-temperature converter, and the resistance temperature sensor comprises a plurality of thermal resistors circumferentially arranged around the first heating device; the circuit temperature control module comprises a circuit temperature sensor and a second heating device; the main control unit controls the second heating device to control the circuit temperature at the safe working temperature according to the circuit temperature detected by the circuit temperature sensor, and calculates the wind speed and the wind direction according to an ambient temperature value obtained by the ambient temperature detecting module, a gas pressure value obtained by the gas pressure detecting module and temperatures values of the thermal resistors. The size of the provided system is small, and integrated measurement of meteorological parameters can be stably and reliably conducted in a low temperature and low pressure environment.

Description

technical field [0001] The invention relates to the technical fields of aviation and spaceflight environment measurement and ground testing, in particular to a high-altitude flat-panel meteorological parameter measurement system and a measurement method. Background technique [0002] In the ground thermal test of the Mars rover, Mars environment detection, and stratospheric environment detection, the measurement of the small wind speed in the low pressure environment has always been one of the difficult problems. At present, common wind speed sensors can be divided into thermal type, ultrasonic type, pitot tube type, mechanical type, laser particle and other speed measurement methods according to the principle. Among them, mechanical type and pitot tube type are mainly used for high-speed measurement, and their measurement accuracy is relatively low for low wind speed measurement. Low; the ultrasonic type needs to be optimized for the efficiency of the transducer under low a...
