Embodiment

With reference to Fig. 1～5, intelligent prepayment electric expense described in the utility model system, form by the pre-payment management computer of fulgurite reason department and electric user's pre-paying kilowatt-hour meter, electricity user's pre-paying kilowatt-hour meter is provided with supplements module and measure control module with money, the measure control module is that core is provided with metering units b with single-chip microcomputer a, display unit c, control module d and storage unit e, pre-payment management computer f is provided with management short message transceiving module g, setting up data between the central processing unit of management short message transceiving module g and pre-payment management computer f connects, ammeter short message transceiving module h is installed in the pre-paying kilowatt-hour meter, set up data between ammeter short message transceiving module h and the single-chip microcomputer a and connect, pass through the note system Data transmission between management short message transceiving module g and the ammeter short message transceiving module h.Because the utility model has utilized ready-made note system, the electric user mobile phone i that therefore intelligent prepayment electric expense system can utilize electric user to hold, between ammeter short message transceiving module h and the electric user mobile phone i by the note system Data transmission.Guarantee that the user can obtain relevant information immediately.

Management short message transceiving module g and ammeter short message transceiving module h can adopt the GSM short message transceiving module, pass through GSM note system Data transmission between management short message transceiving module g and the ammeter short message transceiving module h.Perhaps, management short message transceiving module g and ammeter short message transceiving module h adopt the CDMA short message transceiving module, pass through CDMA note system Data transmission between management short message transceiving module g and the ammeter short message transceiving module h.Management short message transceiving module g and ammeter short message transceiving module h can adopt the TC35I chip to realize.During concrete enforcement, the TC35I chip also need be established peripheral tandem circuit, for example timer 555, Transistor-Transistor Logic level serial ports.The MAX232 chip is the serial ports commonly used of computer, connects for convenience, and the management short message transceiving module g of the utility model embodiment is provided with 9 needle serial port DB.By the grafting of 9 needle serial ports, the output of the data of TC35I chip can be connected to the serial ports of pre-payment management computer f.Power supply POWER provides operating voltage after voltage regulating module LM2914 pressure regulation, operating voltage is labeled as BAT, and the data linkage flag between management short message transceiving module g and the pre-payment management computer f is RXDO, TXDO.The Transistor-Transistor Logic level serial ports of ammeter short message transceiving module h then links to each other with the Transistor-Transistor Logic level serial ports of single-chip microcomputer a and gets final product, and data linkage flag therebetween is RXD1, TXD1.Said chip is the existing product of selling in market, and it is convenient to implement, but specifically uses reference chip service manual and pin explanation.

The measure control module is made up of single-chip microcomputer a, metering units b, display unit c, control module d and storage unit e.Single-chip microcomputer a is a data processing centre (DPC), and main effect is to carry out the instruction that ammeter short message transceiving module h passes over, and user's electricity consumption data are measured computing; The effect of metering units b is being converted to digital pulse signal with electrical load power and measuring processing for single-chip microcomputer a the user; The effect of display unit c is that the real-time circulation of user's power information is shown for user inquiring; The effect of storage unit e is the various data parameters of preserving ammeter; The effect of control module d is to carry out the control signal that single-chip microcomputer a sends, and cuts off or connecting subscribers participating supply line.The utility model embodiment has adopted common chip AT89C52 as single-chip microcomputer a, because this chip and peripheral circuit belong to mature technology, for example storage unit e adopts the 24C32 chip.Can select concrete chip as required for use during concrete enforcement, the connected mode of AT89C52 chip and peripheral circuit can be referring to chip service manual and pin explanation, for example: pin 32～39 transmitting display signal therefor P00～P07 are to display unit c, and display unit can adopt the charactron display when specifically implementing; Metering units b inserts pin 14 with electric impulse signal output; Control module d is picked out by pin 17 with electric impulse signal; Storage unit e is connected with pin 23,24.During concrete enforcement, the TC35I chip is connected with 10,11 pins of AT89C52 chip.

The workflow of the utility model embodiment is: (1) is when the user needs electricity consumption, earlier to the power supply department purchase power consumption index of paying tariff in advance.Power supply management department supplements instruction through management short message transceiving module g to this user's pre-paying kilowatt-hour meter transmission by the sale of electricity management software on the pre-payment management computer f.If successful recharging then ammeter sends " successful recharging " information by SMS module to power supply management department and user, supplement instruction with money up to successful recharging otherwise continue to send.(2) the single-chip microcomputer a in the ammeter is kept at data such as power consumption index in the storage unit e after receiving instruction, when user power utilization, metering units b converts power consumption to digital pulse signal and handles and preserve for single-chip microcomputer a, power consumption with recording user, (as 1 degree) promptly deducts this number in the electric index of purchasing of user when record reaches a unit, preserves remaining sum simultaneously in storage unit e, and in display unit c, demonstrate power consumption and dump energy, so constantly move.(3) when judging dump energy and reach warning charge value or electric weight and exhausted, single-chip microcomputer a sends warning message by ammeter short message transceiving module h to power supply department, and on display unit c, also demonstrate warning message, perhaps send the note of " please supplementing with money as early as possible " content, remind the in time continuous purchase power consumption index of paying tariff of user from trend electricity user mobile phone i.(4) after power consumption index that the user purchases uses up, single-chip microcomputer a sends the control signal of operating a switch, and makes control module d cut off user's supply line, and the user is electricity consumption again.
