High-reliability relay communication system suitable for field unattended station

Abstract

The invention discloses a high-reliability relay communication system suitable for a field unattended station, overcomes the defects of high overall power consumption, complex power supply system anddifficulty in field construction of an RTU (Remote Terminal Unit) technology, and can obviously reduce the power consumption of the whole monitoring and early warning system by reasonably configuringa small number of all-network communication modules and a large number of low-power-consumption modules in an area. A solar battery and a storage battery pack do not need to be additionally arranged,so that the system erection and construction difficulty is greatly reduced; the defects that an existing RTU technology lacks relay communication capacity and is prone to losing the monitoring and early warning functions of a data terminal and a system are overcome, an MESH network is built between multimode communication units, a star network is built between the multimode communication units anda control center, and the high-reliability data communication capacity is achieved. The defects of high construction cost and high communication expense of the existing RTU technology are overcome, and the construction cost of the whole system can be effectively reduced by adopting a scheme of combining a large number of low-power-consumption versions with low price and a small number of high-performance all-network versions.

Description

technical field [0001] The invention belongs to the technical field of natural disaster prevention and forecasting, and specifically relates to a highly reliable relay communication system suitable for field unattended stations, and its main application direction is data transmission of field unattended stations. Background technique [0002] my country is one of the countries most seriously affected by mudslides. Two-thirds of the inhabited mountainous areas are facing the threat of landslides, mudslides, rolling stones and other natural disasters. The country has an urgent need for monitoring and early warning of geological disasters. In addition, in the field of security monitoring of unattended border stations, safety monitoring of major projects such as dams and culverts, the demand for remote monitoring and early warning is also very strong. [0003] Most of these monitoring and early warning needs are located in unattended areas in the wild, and equipment maintenance ...
