采用XMPP与GPRS网络的远程控制系统及其应用

Remote control of field devices over wireless network usually refers to complicated configurations in connections, message format, and logging of control message history. Conventionally, devices are separated, without the capability of easy expansion or easy renovation. Besides, specifically defined equipments are usually expensive. However, remote control technology integrated with GPRS and XMPP only requires low-cost devices. It is an open communication system, and provides higher compatibility as this solution could be distributed onto various devices and is also integrated with remote data collection, remote data logging and remote control. The demo program in this paper has already displayed its capability of control.
