Embodiment Construction

[0028] The structure of the Beidou wind detector is as follows: figure 1 , consists of meteorological sensor part, data acquisition and processing part, Beidou receiver detector, radio transmitter, battery and so on. Meteorological sensors collect meteorological data such as temperature, pressure, and humidity in the air. Meteorological sensors use resistive or capacitive sensing devices to collect meteorological data on temperature, pressure, and humidity in the air, and convert changes in temperature, air pressure, and humidity into resistance values ​​or capacitance values. The change of the wind detector is converted into a digital signal by A / D, processed by the microprocessor module, and the real-time elevation data of the wind detector is sent to the Beidou receiver detector; the Beidou receiver detector receives the signal from the Beidou satellite and combines the elevation data to obtain Real-time positioning data (longitude, latitude, elevation), the positioning dat...

Abstract

The invention relates to an anemometry method of a northern dipper of aerological sounding. The method comprises the following steps: receiving a northern dipper satellite signal, and inputting the signal into a signal amplifier by a northern dipper signal receiving antenna in a northern dipper sonde and a receiver; amplifying the northern dipper satellite signal and sending the signal to a correlator by the signal amplifier to acquire the delay time of the signal emitted by a northern dipper satellite from the northern dipper satellite to the northern dipper signal receiving antenna and the receiver; carrying out altitude computation by a northern dipper anemometry unit directly; obtaining the real-time potential height of a northern dipper anemometry unit by the combined computation of the temperature, the humidity, the air pressure and injection initial altitude which are obtained by real-time sounding in the northern dipper sonde, and converting the real-time potential height into a height so as to realize the real-time altitude computation of the sonde; and realizing the positioning information of the northern dipper receiver of the sonde by the attitude obtained by combining the real-time computation of the temperature, the pressure and the humidity in air, and sending the positioning information to a singlechip to obtain the position and the wind speed of a northern dipper anemometry sounding device in space.

Description

technical field [0001] The invention relates to a high-altitude meteorological detection method and a detection instrument thereof. Background technique [0002] The radiosonde is a telemetry instrument, which can convert the directly sensed meteorological element values ​​into radio signals and send them to the ground. As a result, with the cooperation of corresponding positioning equipment, upper-air wind data can be obtained simultaneously. [0003] For different upper-air meteorological detection systems, the methods of aerial wind detection are different. The current high-altitude detection mainly includes high-altitude meteorological detection radar, radio theodolite, radio navigation, optical wind theodolite and other methods. [0004] At present, there is no ranging device on the wind measuring radar and the radiosonde supporting the radio theodolite used in business. The wind measuring radar must emit high-power electromagnetic waves to obtain the balloon slant di...
