Research Of Radio Supervisory Control And Data Acquisition System Based On GPRS

Supervisory control and data acquisition system (SCADA) has a long history and a very important significance in industrial control field. It could obtain the spot data of some dispersive or unwatched occasions at regular intervals and sent simple control commands. It could organically combine the computer technique and the telecommunication technique, be suitable for many kinds of wide fields.The construction of special cable or wireless communication network is the traditional implementation approach of supervisory control system, which will include a considerable cost to construct and maintain. With the explosive development of telecommunication technology, a kind of new low-cost and wide-band communication method will be provided, which is General Packet Radio Service (GPRS).1. This paper gives a discussion on the network construction and work...
