摘要
瞬态场的测试节点采用上、下位机模式实现其功能。上位机负责无线数据的收发、自组网、控制命令的接收,控制下位机并读取存储器的数据。该文采用结构化和模块化网络编程语言nesC编写其程序。下位机负责采集各种试验信号,完成数据的快速存储并进行相应的数据处理,软件编程采用VHDL语言。在自研平台DJ1.1上对高频信号的采样和多节点组网的实验结果表明,该平台的软件系统稳定可靠。
The nodes implement function by adopting host-guest in testing instantaneous field.The host takes charge of wireless data communications,self buildup meshwork,and controlling command received,controls the guest and reads data from memory.The program is written by nesC which is a configurable and blocking program language.The guest takes charge of sampling all kinds of testing signal and saving data fleetly and processing data.It is approved that the software system is steady and reliable by experiments of sampling high frequency signal and many nodes forming meshwork in the DJ1.1 platform.
