摘　　要：针对无线EPA接入设备中蓝牙、ZigBee等无线通信技术传输距离短、不利于远程监控的缺点,设计了基于GSM功能的无线EPA接入设备。考虑到移动通信网络实时性不高的特点,提出了在EPA控制网络的L2网段设计GSM接入点的方案。分别从硬件设计、报文转换、地址映射等角度,对GSM接入点的设计流程进行了研究。测试结果表明,GSM接入点能够较好地满足EPA微网段远程监控的需要,商用无线通信技术也必将引领未来无线控制网络的发展方向。Aiming at the disadvantages of the wireless communications technologies, including Bluetooth and ZigBee used in EPA wireless access equipment, which have the short communications distance not suitable for remote monitoring, so the wireless access equipment based on GSM function is designed. In addition, considering the mobile communication network does not offer very good real-time performance, thus the GSM access is designed in L2 segment of EPA control network. The design procedure of GSM access is researched in the aspects of hardware design, message conversion and address mapping. The testing result indicates that GSM access well meet EPA micro network segment remote monitoring demand; and the commercial wireless communications technology will eagerly look forward the developing trend of wireless control network.
