Principle of work of the present utility model is: because decimal place character wheel 2, individual position character wheel 3, ten character wheels 4, hundred character wheels 5, kilobit character wheels 6 are in complete 0 state; at this moment; recess 46 lateral alignment of above-mentioned each character wheel protruding plate 45; the wheel of complete 0 acquisition sensor wheel 8 enters in the recess; be subjected to the effect of acquisition sensor retracing spring 9; poke rod 17 upwards; release lever 18 upwards; support bar 20 upwards; balanced lever 22 returns; by guy guard 25, make backguy 26 returns, valve 47 is in closed condition.
The user will insert in the external cell box 29 with the IC-card of legal data, and is connected with control circuit 28 by interface.At this moment; plug-in card switch 38 closures; the electric power of battery 36 offers control circuit 28; give data protection electric capacity 32 chargings by isolated from power diode 33; after being full of; single-chip microcomputer 30 works on power; begin to read data in the IC-card by IC-card seat 37; after correct; in the writing data into memory in the IC-card 31; data according to storer 31 begin the inverted counter; this moment, status indicator lamp 34 was lighted; single-chip microcomputer 30 drive motor triodes 35; motor and speed reduction unit 16 are started working; one group of output at first drives clutch for clutch control wheel 14; on the clutch for clutch control wheel 14 skewed slot is arranged; when the motor shaft turn of inside; be subjected to the effect of skewed slot; clutch for clutch control wheel 14 is moved to the left; thereby promotion intermediary wheel 11 overcomes the acting force of retracing spring 10 to be moved to the left; break away from input reversing wheel 12; and make intermediary wheel 11 and inverted counter power wheel 13 meshing; through a mistiming; second group of output shaft of motor and speed reduction unit 16 drives inverted counter power wheel 13, decimal place character wheel 2 is rotated in the forward, in the rotary course; whenever turn around; inverted counter power wheel number of turns detector switch 27 is delivered to single-chip microcomputer 30 (single-chip microcomputer can adopt PIC1673A) once with data, and the data (or examining and making cuts from the internal memory of single-chip microcomputer 30) of the user's purchase of examining and making cuts from storer 31 (can adopt Flash), when the data in the storer 31 are 0; the inverted counter works finishes, and what counter showed is the data that the user buys.If user's remaining data is not 0 o'clock, by above-mentioned data input, data will superpose automatically.
In metering process, the counter that is originally just changeing, by input reversing wheel 12 oppositely, make by the data back of inverted to reduce, until being 0, valve-off 47 or switch.
After the data input, the character wheel rotation, the recess 46 of character wheel protruding plate 45 is taken turns 8 jack-up with complete 0 acquisition sensor; be subjected to 19 effects of release lever retracing spring; poke rod 17 returns, release lever 18 returns, release lever 18 are against on the support bar 20, are subjected to support bar retracing spring 21 effect, and balanced lever 22 can move left and right; at this moment; in the instrument outside, stir handle 24, push rod 23 promotes balanced lever 22 and moves; thereby the backguy 26 in the pulling guy guard 25 makes valve 47 or switch opens.
Before the inverted counter works is not finished as yet; the user breaks away from battery; this moment, the P0 mouth by single-chip microcomputer 30 detected power down information; write in internal storage 31 by the data of data protection electric capacity 32 with single-chip microcomputer 30 internal memories this moment; when powering on once more, continue to finish the work of inverted counter.Isolated from power diode 33 prevents data protection electric capacity 32 back discharges, and status indicator lamp 34 indication users have finished inverted work.
The advantage of the utility model and prior art is: need not power supply and keep system works, therefore do not exist dried Disturb the unreliable problem with data loss problem and battery and voltage detecting circuit existence; With low cost, suitable Close in enormous quantities and apply; Although use IC-card as exchanges data, internal control circuit does not participate in meter Amount and cutting-off controlling also need not be kept by electric power at ordinary times, therefore are not afraid of any type of attack.
