Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model comprises a plurality of transformer stations 1, switch 2, master server 3, a plurality of optical fiber transmitting-receiving transponder 4, access server 5, sale of electricity client computer 6, contactless card reader 7, monitoring client computer 8, dispatch automated system 9, GPS receiving trap 10 etc.Primary controller in each transformer station 1 comprises master controller 12, programmable logic controller (PLC) 13, communication switch 14, relay group 15, fiber optical transceiver 16, noncontact IC card module 17, GPRS module 18, touch LCD screen 19, a plurality of watt-hour meter 20 etc.

Software, monitoring of tools service software during master server 3 main operation schools, the data that all softwares are used all adopt Database Systems support.The sale of electricity client computer 6 main pre-payment management systems that move; The system manager can carry out operations such as authority is provided with on sale of electricity client computer 6; The operator can operate the pre-payment management system on sale of electricity client computer 6, operation such as supplement with money with wherein current collection administration module.The monitoring client computer 8 main pre-payment management systems that move; Can on monitoring client computer 8, operate the pre-payment management system, supplement audit with money, supplement operations such as error correction with money with financial monitoring module wherein.Access server 5 must dispose two network interface cards, the CMNET network 11 of network interface and China Mobile links to each other and (adopts optical fiber or E1 mode, concrete access way and expense, consult to determine by power supply administration and China Mobile), another network interface links to each other with power supply administration pre-payment LAN (Local Area Network), middlely carries out data-switching with access service software.The monitored instruction of all payment systems all passes through the access service software of access server 5, is forwarded to each transformer station or user's wireless prepaid control system; Equally, the power information of all wireless prepaid control system is forwarded to prepaid server and handles by the access service software of access server.

The communication mode that native system adopts fiber optic network and wireless GPRS network to combine.For the transformer station that has optical fiber to connect, primary controller in the transformer station has network interface, connect optical fiber by fiber optical transceiver 16 and carry out communication with regard to energy and master server 3, message transmission rate is 10Mbps, the realization local data is regularly uploaded, and is defaulted as three minutes once, accepts the order of master server 3 simultaneously at any time, carry out associative operation, as the Long-distance Control gate etc.Because data volume is little, this communication is not subjected to capacity limits, as system's increase-volume from now on, to communication speed substantially without any influence.Book server regularly carries out poll to each primary controller, obtains user's power information.

For 32 transformer stations are arranged, there is the payment system of 32 main system devices in each transformer station, and the data of each poll comprise that size is each controller of 20bytes/, and then the transmission time is wanted 1 minute to data at least back and forth.Consider that in addition controller has abnormal conditions to occur, interrupt suddenly that server need be provided with delay time and judge whether controller is normal such as the circuit of certain controller.So the standard poll time (data collection cycle) is set to 3 minutes.The poll time can be provided with in the pre-payment management system.The payment system scale is less in advance, if having only 9 transformer stations to be connected with server, the poll time can be set to 1 minute.

As the reserve communication of optical-fibre communications, when optical-fibre communications was interrupted, system changed the GPRS communication automatically over to, and the primary controller that is located in the transformer station connects to form the wireless GPRS network by standard serial port and GPRS module, and it is the same to finish function.Master server and master controller adopt point-to-point communication, and traffic rate is 30～50kbps.This communication is not subjected to capacity limits yet, system's increase-volume to communication speed substantially without any influence.

For the calculating of each user power utilization information, be to carry out in each controller the inside.Information such as the user prepayment amount of money are when the operator carries out prepaid electricity selling, after owing the electricity charge by pre-payment management system deduction is old, send sale of electricity and instruct to controller, major parameter comprises: Customs Assigned Number, electricity consumption period, the period electricity price, the electricity price classification, the residue alarm amount of money, the pre-payment amount of money (can just can bear by the amount of money, positive number is represented money charging, and the amount of money is revised in the negative representative) etc.

The master controller 12 that is located at each transformer station to programmable logic controller (PLC) 13 sending controling instructions, is carried out relevant control by it by standard serial port according to the condition of default and the instruction of master server 3 transmission, comes pilot relay group 15 output corresponding signals.System default control output information has: the intact signal of electricity charge alarm signal, the electricity charge, watt-hour meter fault-signal.The watt-hour meter fault-signal is expressed be primary controller can't with the watt-hour meter communication.The primary controller that is located at transformer station can receive the data that contactless IC card read/write module 17 transmits, and judge whether by the encryption and decryption verification legal, as legal, just data are placed on corresponding ammeter data field, in order to gather the comparison of electric weight, realize pre paid functionality, and provide and supplement debugging functions with money.The data state standard cryptographic algorithm guarantees safe and reliable.Master controller 12 is being undertaken major functions such as collection, computing, communication, control, pre-payment control.

Communication switch 14 is directly controlled by master controller 12, the actual change-over switch that is equivalent to, and control switches to different watt-hour meter 20 and carries out data acquisition.Programmable logic controller (PLC) 13 (PLC) major function is to accept the instruction of master controller 12, carries out corresponding actions, pilot relay group 15 output useful signals, and PLC inside is programmable, can revise flexibly according to actual conditions.Noncontact IC card module 17 is responsible for reading the user card punching data, and is sent to master controller 12.GPRS module 18 directly is connected with master controller 12 serial ports, has the function of reaching the standard grade automatically, and going offline reconnects automatically, guarantees that system data can uninterruptedly be sent to master server 3.Fiber optical transceiver 16 is exactly the equipment that master controller 12 network interfaces is converted to optical fiber interface, directly just can connect optical fiber in the transformer station by fiber optical transceiver 16, finish and master server 3 between networking.
