The Optimal Deploy Method of Multi Redundancy FPGA Gateway Design

Prevention of geological disasters is essential in highaltitude or semi high mountain plateaus and hilly areas. To monitor disaster, the manuscript presents a design method of distributed redundancy FPGA (Field Programmable Gate Array) gateway. This gateway can test a series of parameters in order to estimate geological disaster. However, the detection of geological disasters is complex work, for the test fields are located in different monitoring place and every place has a different environment condition. Meanwhile, the same type of monitoring parameters should be monitored more than two places, and the place may be changed, it results in the problem of distributed redundant monitoring. So, there are three kinds of monitoring actors: the active detection one, the auxiliary detection one, and the redundancy one. And these actors can transform one to the other. To obtain the balance between the communication resources and effective detection of geological disasters, the design of distributed redundancy gateway should be dynamic deployed based on the environmental and detection condition change. The article adopts a redundant gateway design using multiple FPGA in hardware, and uses distributed redundant decision-making method in software. It uses a wireless redundancy decision-making optimization method, and gives a design example for ‘the atomic cloud’ application of infrasound monitoring.
