基于GSM的无线数据传输系统

GSM在数据传输应用上,具有价格便宜、覆盖范围广等特点,特别适用于需频繁传送小流量数据的应用,如车辆调度、监控、监测等领域。本文利用GSM公共网络进行数据传输的方法,通过标准的RS232接口结合己有的单片机系统,实现数据的无线传输,并且监控终端也不再仅局限于PC机,也可以是移动电话或其他移动终端。

Wireless Data Transmission System Based on GSM

The application of GSM has its own advantages, such as low price and wide scope covering, which is especially suitable in the field that the data is transmitted frequently but the flow of is low, for instance, at tempering vehicles, supervising and navigating. The thesis uses the method of data transmission on GSM network, and in virtue of the standard RS232 interface and the existing single chip micyoco GSM wireless network to realize wireless data transmission. The monitoring terminal is not limited in PC machine, also can be mobile telephone or other mobile terminal.
