GPS meteorological sounding meter design method using radio frequency to transmit data

Abstract

The invention discloses a GPS meteorological sounding meter using a radio frequency to transmit data. The GPS meteorological sounding meter includes a helium balloon and a main body; the main body is hung below the helium balloon; the main body comprises a shell; the shell is internally provided with a circuit board and a battery; a GPS module connected with a GPS antenna, a single-chip microcomputer, a temperature and humidity sensor, and an atmosphere pressure sensor are arranged on the circuit board; a data output end of the GPS module of the GPS antenna is connected to a serial input end of the single-chip microcomputer; the temperature and humidity sensor, the atmosphere pressure sensor are connected with a parallel I / O port of the single-chip microcontroller; a serial output end of the single-chip microcomputer is connected with a wireless data transmission module; the wireless data transmission module is connected with a communication antenna; and the battery is connected with the circuit board by a wire. The helium balloon lifts off and then uses the wireless data transmission module to transmit the meteorological data collected by the temperature and humidity sensor and the atmosphere pressure sensor and the geographic location information collected by the GPS module to the ground information center.

Description

technical field [0001] The invention relates to the technical field of meteorology, in particular to a GPS meteorological radiosonde which uses wireless radio frequency to transmit data. Background technique [0002] The observation and study of the atmospheric boundary layer are of great significance for meteorological and climate forecasting. Meteorological radiosonde is an important and commonly used meteorological observation equipment. It usually has temperature and humidity sensors, air pressure sensors, etc. to collect the altitude, temperature, humidity and atmospheric pressure of the observation location, and transmit the data through mobile communication. to the ground receiving center. However, in practical applications, it has been found that some remote areas do not have mobile communication signals, resulting in the inability to transmit data in time and delaying the collection of meteorological data. The data is distorted, which is not conducive to weather f...
