Embodiment
The utility model is done the explanation in a step below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model network prepayment electricity-selling system comprises CPU card, table meter unit, concentrator unit, communication unit and main station unit at least; Wherein,
The CPU card is used for finishing and purchases electricity and purchase electric weight to showing to count to append in the unit;
Table meter unit in order to the power consumption of metering user, and is uploaded to this power consumption concentrator unit and receives the data and the order that pass under the concentrator unit with carrier system by line of electric force and carry out corresponding action;
Concentrator unit in order to the electricity consumption data centralization with each table meter unit, its downstream, and is uploaded to main station unit and receives main station unit by communication unit and carry out corresponding action by data and order that communication unit passes down;
Communication unit intercoms with main station unit mutually in order to connect concentrator unit by public communication network;
Main station unit is in order to receive data that concentrator unit uploads and it is carried out statistical study and according to user power utilization amount situation with purchase and pass corresponding data and order under the electric weight situation.
Wherein, above-mentioned CPU card preferably adopts the Contact Type Ic Card that meets the ISO7816 international standard, also can adopt other form certainly, as radio-frequency card etc.
As shown in Figure 2, above-mentioned table meter unit is made up of main control chip and connected key-press module, E-SAM key authentication module, protection module, display module, infrared/the 485/PLC communication module, power on/off module, memory module, metering module and supply module; Wherein, infrared/485/PLC communication module is used to be provided with real-time clock, the timesharing parameter of table meter unit, and can carry out operations such as parameter modification, status data read, check meter by communication interface his-and-hers watches meter unit; E-SAM key authentication module is in order to sticking into capable safety certification to CPU, metering and the status data in the storage list meter unit simultaneously, table are counted main control chip in the unit only plays data transmission in verification process effect, do not relate to data encryption and decipherment algorithm.
