A multi-mode data management and communication system suitable for field unattended stations

Abstract

The invention discloses a multi-mode data management and communication system suitable for unattended stations in the field. Through the mutual backup of various communication means and the establishment of a MESH network between each multi-mode communication unit, the multi-mode communication unit and the control A star network is established between the centers to achieve highly reliable data communication capabilities, which overcomes the shortcomings of the existing RTU technology, such as single communication means, prone to data terminals, and loss of system monitoring and early warning functions; overcomes the traditional communication signal perception algorithm for communication channel quality evaluation False alarms and missed alarms are prone to occur, and the communication mode switching time is too long, which affects the immediacy of data transmission and system reliability. By designing a channel quality fast sensing algorithm based on heartbeat packet data smoothing strategy and communication based on double early warning thresholds The fast mode switching strategy can effectively improve the sensitivity to communication channel quality perception and shorten the communication mode switching time.

Description

technical field [0001] The invention belongs to the technical field of natural disaster prevention and forecasting, and specifically relates to a multi-mode data management and communication system suitable for field unattended stations. The main application direction is data management and communication 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 e...
