The Research Of The DDM System In CDMA

This text explain and rely on wireless to divide into groups wireless businesses CDMA emphatically, develop and structure electric power run in the system by wireless data, And has explained in detail that the wireless data of electric power run the centre, user and uses the platform system and develops scheme, systematic function, network structure, procedure flow, The network security is controlled. Utilize CDMA network for the first time at home, realizes dispatcher's automation of electric power , realizes that the wireless information is monitored and control wireless and long-rangly long-rangly , Relying on CDMA and divide into groups wirelessly the wireless business development wireless data has very wide development prospect of market to run the centre, Can obtain the good social benefit and economic benefits at the same time , have far-reaching meanings in accelerating the informationization development that the electric power worker accused of the field.The main technology that system involves:1.Adopt wireless communication technology and realize that the multimedia information is inserted wirelessly.2.Function of finishing long-range the geographies of monitoring point make a reservation, attribute analyse , network structure is analysed mainly by GIS geographical information systems etc, User control manage at GIS geographical information systems visual to take interface terminal station, Realize the management to the monitoring point of the data.3.The network technology of the computer, in this system, Combine the LAN, technology of WAN , multiple computer technology of multimedia technology, the compunication and long-range control operation of computer together organically, Finish controlling the function systematically.
