GPSGPS Multifunctional turbulent current sonde and its measurement method

Abstract

The invention discloses a GPS multifunction turbulence radiosnode and a measurement method thereof. The radiosonde comprises a sensing part (1) including a temperature pulse sensor (11), a Barometric pressure sensor (12), an atmospheric temperature sensor (13) and a GPS sensor (14), a signal converting part (2) including an analog-to-digital converter MAX197 and a singlechip AT89C2051, a transmitting part (3) including a lever translator and a transmitter (31), and a power supply (4), all of which are used to convert electric signals output by the sensors into digital signals, and calculate, analyze, code and transmit the digital signals. The method comprises the following steps of: receiving the signal output by the sensors and outputting digital signals; particularly setting time slice for acquiring the output of the sensors and acquisition frequency and determining the acquisition proportionality coefficient of the sensors according to the acquired sensor; and processing and coding the data converted into digital signals and transmitting the data converted into digital signals to the transmitting part to be transmitted. The invention can accurately position and measure the atmosphere turbulence and wind direction and speed at the measurement points.

Description

technical field [0001] The invention relates to a radiosonde and a measurement method, in particular to a GPS multifunctional turbulent flow sonde and a measurement method thereof. Background technique [0002] With the rapid development of optoelectronic technology, the importance of optical turbulence has been paid more and more attention. In the process of laser transmission, the turbulence effect causes the drift and expansion of the beam; in the image application, the turbulence effect causes the shaking and deformation of the image; the turbulence also reduces the resolution of the astronomical telescope. In order to quantitatively study various phenomena of laser light passing through the turbulent atmosphere, and to solve various optical engineering problems related to these phenomena, it is necessary to deeply study the optical turbulent structure of the optical path, and study its variation law and statistical characteristics. The obtained turbulence data can serv...

Problems solved by technology

However, there are deficiencies in this kind of radiosonde. First of all, it has a single function. Although it can measure the turbulence, temperature and pressure in the atmosphere, it cannot give where it was measured at the same time, let alone give it accurately. The coordinate points during measurement; secondly, the degree of intelligence is not high, and the various signals measured cannot be processed and analyzed in real time, especially the wind speed and wind direction in the atmosphere cannot be obtained in real time, which is very important for turbulent flow. The analysis of the cause and development trend is very important; again, it is not easy to recover. The radiosonde carried by the balloon floats with the wind in the atmosphere. Since there is no coordinate information of the radiosonde, it is not clear where it will fall. Known
