Intermediate layer basically is: Communication server, its are main the function is collect device centrally in the spot dispersedly, at the same time far pass to the station to accuse a layer, layer of the spot that finish and station dominate the data between the layer alternant. The station accuses a layer: Set the facility such as power source of high-powered industry computer, monitor, UPS, printer, acoustics. Supervisory system installation is on the computer, concentration collects indication spot equipment to run a state, show an user with interactive form. Above network appearance all uses RS485 interface and MODBUS-RTU communication agreement, RS485 uses screen line to transmit. 2.

Main function of the system 2.

1 data collects the base that with processing data is collected is distribution monitoring, data is collected main by ground floor muti_function network appearance is collected finish, this locality that realizes long-range data shows in real time. Need finishs collection signal to include: φ of COS of factor of P of Hz of I of electric current of three-phase voltage U, three-phase, frequency, power, power, report spends Ep, long-range equipment to run the data such as condition. Data processing basically is show the electric parameter that collects by the requirement well and truly to the user in real time, the automation that achieves distribution monitoring is changed and intelligence changes a requirement, stock the data that collects at the same time the database inquires for the user. 2.

2 interactive systems are offerred use simply, easily, good user uses an interface. Use complete Chinese interface, CAD graph shows low-pressure distribution system is electric advocate hookup, switch of indication; of quantity of imitate of; of refresh of real time trends measures status of equipment of indication distribution system and picture of; of parameter of travel of corresponding solid fortune indication; calls the police the record shows etc. 2.

3 breakdown call the police when reaching accident recall to produce operational failure in distribution system, phonate of can seasonable hair calls the police clew user answers breakdown loop in time, the time ground that at the same time self-recording incident produces is nodded, with be being inquired by the user, recall breakdown reason. Nextpage2.

4 databases build quantity of the as main as inquiry telemetering that finish and Yao letter quantity to time collect, and build a database, make etc regularly, print in order to offer user inquiry. 2.

Management of cost of 5 electric energy has day, month automatically, year electric energy statistic, can have set of period of time of pointed, peak, smooth, cereal, implementation has electric energy to divide chronometer to expend a function, generate day, month, annals to express at the same time, voltaic graph. 2.

The user amount that management of 6 users attributive can be added according to buyer requirement and deletes software and the limits of authority that set an user. Be aimed at the user of different level, set different attributive group, because handle production by accident artificially,prevent, the loss that the life brings, achieve the security of distribution system, move reliably. 2.
