The utility model has the advantages that volume is little, cost is low, power consumption is little, easy to operate, reliability is high, combines with the normal domestic use gauging table, can play the effect of prepaid, and need not regularly check meter to the doorstep, simplified charging process, improved efficiency, high practical value has been arranged.

Accompanying drawing 1 is total block scheme of prepaid controller;

Accompanying drawing 2 is example structure synoptic diagram of the present utility model;

Accompanying drawing 3 is physical construction synoptic diagram of quantitative register.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing: single-chip microcomputer 31 is mainly by central processing unit 31-3, program storage 31-1, encryption memory 31-2, output control interface 31-4, input control interface 31-5, output control interface 31-6 and data bus DD, address bus AD, control bus CD forms.Single-chip microcomputer 31, keyboard 33, light-emitting diode display 32, the annexation of stepper motor 34 and quantitative register 35 is FPDP of program storage and encryption memory, address port, control port respectively with the data bus of central processing unit, address bus, control bus joins, each output port of keyboard is by the data bus of input control interface and central processing unit, address bus, control bus joins, each input port of light-emitting diode display is by the data bus of output control interface and central processing unit, address bus, control bus joins, the input end of stepper motor is by the data bus of output control interface and central processing unit, address bus, control bus joins, the rotation axis 22 of stepper motor is by gear 17 and quantitatively character wheel 6 left side tooth combinations of register, quantitatively register is by character wheel 1,2,3,4,5,6, rotor wheel 7,8,9,10, worm screw 11, worm gear 12, gear 13,15,16, disk 14, rotation axis 18,19,20,21 grades constitute, see Fig. 3, wherein character wheel 5,6 with character wheel 1,2,3,4 on same axle but direction is opposite, rotor wheel 10 and rotor wheel 7,8,9 on same axle but direction is opposite, and the left side tooth of character wheel 4 and the right tooth of character wheel 5 stop mutually that on the surfaces of revolution gear 15 and rotation axis 19 flexibly connect, disk 14 is fixedlyed connected with rotation axis 19, gear 15 sides have circular hole 23 to be used for threading, the control input switch, and there is circular hole 24 the disk side.Single-chip microcomputer model: PIC16C84

Store many passwords in the encryption memory of prepaid controller in advance, these passwords are deposited according to the order of sequence, watchdog routine in the program storage is according to current password comparison in the password of keyboard input and the encryption memory, the password coupling, then the control step motor makes numeral of character wheel 5 upsets, and prepares to receive Next Password.Numeral of character wheel 5 every upsets makes quantitative register increase by 100 count number, and when quantitative register has been counted 100 amounts, hundred figure place carries make character wheel 4 upsets.If do not input password in advance, character wheel 4 will be subjected to character wheel 5 the right teeth to be stopped, can't finish rotary movement, rotation axis 19 is remained static, and gear 15 is still rotating, distance is elongated between the circular hole 23,24, tightrope 25 Drawing switches, cut off the gauging table input channel, worm screw 11 stops operating, and quantitatively register suspends counting.At this moment, the user must arrive the expense that specified quantity is paid in the cash desk, can inquire password by the gauging table numbering, password is imported by the keyboard of prepaid controller in the back of going home, and the control step motor makes numeral of character wheel 5 upsets, the resistance of character wheel 4 disappears, rotation axis 19 is in active state, and tightrope 25 pulling force disappear, spring 26 Drawing switches, connect the gauging table input channel, quantitatively register is counted again.
