摘要
基于SIM900A无线通信模块,设计和实现了一个环境在线监测短信反控系统。该系统在嵌入式Linux平台下,通过编程实现了一个标准的多路复用协议———GSM 07.10 Multiplexer Protocol,并结合"伪终端(pseudo tty)"技术,在串口和应用层之间搭建一个"串口通信链路复用层",成功解决了SIM900A串口分时复用问题,从而实现了使用GSM短信息远程控制环境监测终端设备的目的。
Based on wireless communication module - SIM900A, a SMS Anti-control system in environment on-line monitoring is designed and realized. By utilizing pseudo-terminal technology and programming to achieve GSM 07.10 Multiplexer Protocol in the embedded Linux platform, the system implements a serial multiplexer layer between serial port and application layer, and solves the problem of time-multiplexed in serial port of SIMg00A. So, the purpose of mobile remote controlling environmental monitoring equipment is achieved.
