Design and realization of remote-control terminal based on GPRS

To guarantee unmanned machinery rooms work normally and safely and promote maintenance lever, the paper presents the remote-control terminal based on General Packet Radio Service(GPRS). The remote-control terminal can monitor temperature, humidity, fire, water leaching and burglar etc, and alarm the maintainer the accident/abnormal behavior. Especially, the remote-control terminal can control the air conditioner automatically without hardware changing of the air conditioner. The terminal can work with monitoring center to setup up a powerful monitor system. With the using of the terminal, the machinery rooms can be monitored and controlled in anywhere at anytime on any device. It makes the machinery rooms maintenance become easy and efficient.
