Abstract

The invention provides a distributed wireless meteorological encoding monitoring method, a device and a system, and relates to the technical field of meteorological monitoring. Meteorological data can be transmitted effectively in a severe meteorological environment, and the transmission efficiency is improved. The distributed wireless meteorological encoding monitoring method comprises the steps that sensor nodes perform RS (Remote Sensing) encoding encryption on the acquired meteorological data by an FPGA (Field Programmable Gate Array) chip; the encrypted meteorological data is transmitted to a monitoring station computer in a wireless manner; and the monitoring station computer is used for receiving the encrypted meteorological data, decoding the encrypted meteorological data, then performs data preprocessing and storage, and sending the data to a meteorological data center by the Ethernet. The distributed wireless meteorological encoding monitoring method is mainly used for a distributed meteorological automatic monitoring system.

Description

technical field [0001] The invention relates to the technical field of meteorological monitoring, in particular to a distributed wireless meteorological coding monitoring method, device and system. Background technique [0002] At present, the meteorological monitoring systems adopted at home and abroad can be divided into centralized and distributed according to the system structure. Among them, in the centralized monitoring system, a control center is responsible for the unified processing of various information in the system and the distribution of tasks. Since all control tasks are completed by the control center, once the control center fails, the entire system will not be able to operate normally. . The distributed monitoring system assigns tasks such as information processing to each sub-unit within the system for collaborative control and management. Once a sub-unit within the system fails, other units can still continue to operate normally, thereby improving the re...
