RS code-based distributed wireless meteorological monitoring method, monitoring station and system

Abstract

The invention provides an RS code-based distributed wireless meteorological monitoring method, monitoring station and system and belongs to the meteorological monitoring technical field. The objective of the invention is to solve problems of low effective transmission efficiency and low reliability of data in an existing distributed wireless meteorological monitoring system under harsh meteorological environments. The meteorological monitoring method provided by the invention includes the following steps that: a sensor node is adopted to acquire meteorological information requiring monitoring, process the meteorological information, and perform RS code encryption on the meteorological information so as to obtain encrypted ciphertext of meteorological data, and transmit the ciphertext of meteorological data to a monitoring station computer; and the monitoring station computer receives the ciphertext of meteorological data, and decodes the ciphertext of meteorological data, and thereafter pre-processes and stores the decoded ciphertext of meteorological data, and transmits the ciphertext to a meteorological data center through the Ethernet. According to the above technical scheme, an RS code mode is applied to wireless meteorological data transmission, and therefore, the RS code-based distributed wireless meteorological monitoring method has the advantages of high data transmission efficiency and high reliability.

Description

technical field [0001] The invention relates to the technical field of meteorological monitoring, in particular to a distributed wireless meteorological monitoring method, monitoring station and system based on RS coding. 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, ...
