Multi-purpose meteorological data wireless transmission system and method

Abstract

The invention provides a multi-purpose meteorological data wireless transmission system and method. The system comprises a transmitter, an antenna group, a combiner and a multi-path signal receiving device and the antenna group, the combiner and the multi-path signal receiving device are connected orderly. The antenna group comprises one or more antennas arranged on the ground in a target acquisition area. The transmitter is communicated with a corresponding antenna. The multi-path signal receiving device is communicated with a control center station and is used for transmitting meteorological data transmitted by the transmitter and orderly passing through the antenna group and the combiner to the control center station. The multi-path signal receiving device is used for transmitting a control command of the control center station to the transmitter through the antenna group. The multi-purpose meteorological data wireless transmission system has the advantages of wide application range, simple structure, high operation efficiency, high use reliability and easy installation, can be used for networking or point-to-point data transmission of a surface weather station, and can also be used for high-altitude atmosphere observation system networking or point-to-point wireless data transmission, and provides an accurate and reliable data base for meteorological data analysis and research.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a multipurpose meteorological data wireless transmission system and method. Background technique [0002] In the field of meteorological detection, data collection is an important field of the meteorological observation system. The accuracy and punctuality of data transmission have extremely high requirements for the meteorological detection system, which provides a strong guarantee for the later weather forecast; while in the ground meteorological The station system mainly uses CAN bus to collect various sensor data, and then uploads to the data center station through wired or wireless (mainly GPRS and SMS, etc.) networks; in the high-altitude meteorological detection system, L-band radar is used to track data. transmission. The existing transmission mode is single, the cost is high, and the application is inflexible. [0003] At present, conventional antennas cover ...

AI Technical Summary

Problems solved by technology

The existing transmission method is single, the cost is high, and the application is inflexible

[0003] At present, conventional antennas cover a fixed area, omnidirectional antenna plane coverage, unable to achieve full hemispherical coverage

Usually, a combination of multiple antennas is used, which needs to be switched by an electronic switch to achieve hemispherical reception. The structure is complex and the installation convenience is low.

[0004] In addition, conventional receivers are all single-channel, limited to one-way point-to-point data transmission, and cannot realize networked data transmission
