Power Supervising System Based On GPRS Network

The author through many year paths, the bridge, the tunnel maintenance experience, in view of the current domestic road lighting, the night scene illumination and the equipment for the power distribution, the tube raises the present situation, to the current several kinds wired, the wireless data transmission technology carries on the analysis, in the comparison foundation, chooses takes the communication in technical front general grouping wireless service (GPRS) the medium, proposed based on the GPRS network intelligent electric power supervisory system. Through the GPRS network's data communication, this system can realize with monitors the sub-station two-way communication, both can from monitor the sub-station to receive each kind of electrical parameter data respectively, and to be able to provide a visualization contact surface for the user, causes the user to be confined at home then understood that the far prescription stands the real-time movement condition, and may to monitor the sub-station according to the actual need to transmit each kind of operational order, the control monitors the sub-station the operational aspect, when and the equipment appears exceptionally or by the robber can send out automatically the alarm; And introduced the use electric cable carrier and the electric current monitor emphatically and so on many kinds of technical electric cable security alarm systems.The present paper's first chapter brief summarized our country electric power communications network's development process and the present situation, the second chapter of contrastive analysis automated system several mailing addresss and the good and bad points, and introduced the GPRS several kind of network plan; The third chapter develops a set of electric power supervisory system is a background, introduced the GPRS communication in the transformer substation utilization and transformer substation automated system's realization. The latter several chapters are engaged in many year tubes according to the author to raise and the system development experience, introduced with emphasis in the electric power supervisory system development applies several key technologies, like the SQL database's application, system software's design and the security warning technology and realize in system's application. Last chapter is to the system development summary and the forecast.
