Embodiment Construction

[0047] As shown in the figure, the electronic radiosonde of the present invention comprises:

[0048] 1. Measuring box: temperature, pressure, humidity acquisition and processing, and modulated output 10K, 20K square wave signal.

[0049] 2. Transmitter: Complete 10K, 20K square wave signal transmission, and generate ranging signal.

[0050] 3. The radiosonde power supply consists of water-filled magnesium batteries.

[0051] The radiosonde is composed of sensors (rod-shaped thermistor, carbon hygrostat, silicon varistor bridge, compensation thermistor), and the pressure sensor of the electronic radiosonde adopts the bellows varactor type.

[0052] The P-band transmitter and radiosonde are embedded in thermal insulation foam plastic, and the shell is made of waterproof paper. The sensor for measuring atmospheric temperature and humidity is placed on the lid of the carton, and the thermistor bracket is turned out when releasing, and fastened with the thin wire of the lid.

Abstract

A method for setting sense signal of sounding device includes using transducer to collect meteorological information of temperature, pressure and humidity; using resistance variation to represent temperature and capacity variation to represent pressure and humidity; converting said variations to be frequency signal and applying 10K and 20K square wave to modulate and code frequency signal; varying sense signal carried by 10K and 20K square wave signal in following variation of air sounding information then sending it to emitter and using 10K and 20K frequency as sub carrier to send air sounding data.

Description

technical field [0001] The invention relates to a high-altitude meteorological detection device, namely a method for setting sensing signals for electronic sounding measurement and a sounding instrument. Background technique [0002] The 59-type code-type mechanical radiosonde for the 705 and 706 weather radars was designed and produced by Shanghai Radio 23 Factory with the support of the National Meteorological Bureau. It was put on the market in the 1960s and has been in use until now. Its core technology is: the temperature, pressure, and humidity sensors are connected to the code barrel through a mechanical connecting rod, and a contact pin at the other end of the connecting rod conducts with the electrode of the code barrel to generate a Morse code signal when the code barrel rotates. The generated Morse code is modulated on the 800M transmitter to transmit the collected sounding data to the ground radar. [0003] The radiosonde has been used in the 701 and 705 seconda...
