| Abstract: | Based on Nios Ⅱ and Beidou first generation system,a meteorological disaster warning information receiving terminal design scheme is proposed to deal with problems of receiving early-warning information in the majority of remote mountain where information receiving blind spot exists and power supply is difficult.By adopting FPGA EP1C12Q240 and RNC2410 RF chip,the cost,size and power consumption of the warning information receiving terminal hardware are reduced.At the same time,by using Nios Ⅱ soft-core processor,this terminal can realize correct receiving early-warning information and alarm through software design.This method has been successfully applied in receiving early-warning information in mountain floods and debris flow-prone areas. |
