摘要: 针对在恶劣的工作环境下工业无线网络WIA-PA的可靠性问题,分析了WIA-PA的特点,详细介绍了WIA-PA终端节点的硬件及软件设计。测试结果表明,设计的WIA-PA终端节点的射频距离在没有外界干扰的情况下为600 m,在有外界干扰的情况下为400 m,满足WIA-PA的需求。Abstract: In view of problem of reliability of wireless industry network WIA-PA under bad working environment, the paper analyzed characteristics of WIA-PA, introduced design of hardware and software of terminal nodes of WIA-PA. The test result shows that distances of radio frequency of the terminal nodes of WIA-PA are 600 m without external disturbances and 400 m with external disturbances, which meet requirements of WIA-PA.
