Abstract: In order to solve the problem that real-time monitoring of distributed system can not be achieved without cable networks, a wireless broaching machine remote controlling system based on general packet radio service(GPRS) was designed, and the procedure of the center computer software was described in detail. Its hardware includes data acquisition and control client, GPRS network, Internet network and monitoring center computer, its software includes operating system, client software and center computer software. The control client is able to preview locally and do PLC controlling actions. GPRS network is always on-line and charging on flow quantity. Center computer controls remotely and switches freely. The result of three-month testing proves that this system has many advantages such as wide geographic application, easy expansion, high reliability, and can greatly reduce the investment and running expenditures.
Key words: general packet radio service(GPRS); control client; remote control; center computer
