摘要
基于无线采集技术,设计了一种通用的可靠的长距离无线数据采集系统。一对编码器/译码器之间数据经卷积编码并使用两条相互备份的无线数据传通道同时发送数据,接收端进行viterbi译码后,接收端的硬件对2路数据的实时校验和判选,实现可靠的数据传输。该系统包括硬件框架、逻辑设计,利用现场可编程门阵列(field programmable gate array,FPGA)作为主控制器,实现了远距离可靠触发、控制和采集。
Based on technology of wireless data acquisition, this paper designs a general and reliable long distance wireless data acquisition system. A pair of encoder/decoder exchanged data by the two mutual backup data transmission channel to send data at the same time. After Viterbi decoding, the receiving end checked the two way data and selected one as the last data. Using this method , we can achieve reliable data transmission. The system included hardware framework design and logic design, using FPGA as a main controller , realizing the reliable controlled detonation and data collection.
