说明：  本文针对目前利用GSM进行无线数据通信的需要，设计了GSM无线数据传输系统的终端。利用日渐成熟的无线通讯网络所建立的数据通道，以短消息作为数据传输方式，开发出基于GSM-SMS的智能无线报警系统。该系统克服了报警有效距离的限制，无线通讯网络能覆盖到的地方均为有效报警区域。此外，系统采用短信互动方式，实现了超距离遥控功能。
(In this paper, the current use of GSM wireless data communication needs, the design of the GSM wireless data transmission system terminals. The use of increasingly sophisticated wireless communications network established by the data channel to the short message data transmission as a way to develop a GSM-SMS-based intelligent wireless alarm system. The system is effective to overcome the distance limitations alarm, wireless communications network to cover the local region are valid alarm. In addition, interactive text messaging system to achieve the ultra-distance remote control function.)
