Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, present embodiment comprises gas meter, flow meter base 2, by-pass valve control 4, counter assembly 5, user data exchange control unit 33, inverted power motor and speed reduction unit control circuit 27, inverted power motor and speed reduction unit 26, probe portion, self-sustaining topworks, the output of user data exchange control unit 33 connects inverted power motor and speed reduction unit control circuit 27 as power supply signal, inverted power motor and speed reduction unit control circuit 27 connect inverted power motor and speed reduction unit 26 and probe portion respectively, inverted power motor and speed reduction unit and 26 counter assemblies 5 join, and counter assembly 5 joins by probe portion and self-sustaining topworks.Self-sustaining topworks comprises self-supporting switch and release lever 37, balance stem 38, control backguy 40 and protection tube 41; balance stem 38 is connected with control backguy 40; control backguy 40 is connected with the rotary valve plate 42 of by-pass valve control 4 inside by protection tube 41, and self-supporting switch and release lever 37 offset with the detection sensing shaft 44 of probe portion.Counter assembly 5 comprises a counter wheel 10, ten counter wheels 11, hundred counter wheels 12, the kilobit counter wheel 13 of detection wheel 20,21,22 and 23 grooves that match of inverted counter wheel 18, band and the probe portion of inner band rotary chute, inverted counter wheel 19 and be against main shaft character wheel retracing spring 17 on the most significant digit kilobit counter wheel 13, inverted power motor and speed reduction unit 26 are connected with the inverted counter wheel 18 of being with rotary chute by inverted counting wheel shaft 19.Inverted power motor and speed reduction unit control circuit 27 comprise central processing unit 28, be connected on central processing unit 28 output terminals with the triode 32 that drives inverted power motor and speed reduction unit 26, be used to store electric flash memory 29, the isolating diode that is used for isolated data 31 that is connected on central processing unit 28 two ends and the data protection electric capacity 30 of user's purchase data etc.Probe portion is surveyed a position on the sensing shaft 44 by being through from the low level to a high position and is surveyed 20, ten on wheel and survey 21, hundred on wheel and survey wheel 23 and kilobit and survey wheel 24 and forms, and the self-sustaining release lever 37 of surveying sensing shaft 44 and self-sustaining topworks offsets.
The utility model principle of work is: combustion gas (rock gas, coal gas, liquefied gas) enters gas meter, flow meter base table 2 from draft tube 1, and gas is supplied with the user from escape pipe 3 through by-pass valve control 4 and used.When the user uses combustion gas, combustion gas is by base table 2, the counter assembly 5 of base table 2 is started working, the writing speed of counter assembly 5 also is directly proportional gas consumption with the user, base table 2 is meshing by counter output shaft 6 and counter assembly 5, by 0.001 counter wheel, 7,0.01 counter wheel, 8,0.1 counter wheel 9, to individual position counter wheel 10 carries, individual position counter wheel 10 by one's carry wheel 14 to ten counter wheel 11 carries, by rounding wheel to hundred counter wheel 12 carries, again by rounding wheel to kilobit counter wheel 13 carries.
When the utility model dispatches from the factory, counter assembly 5 data presentation are 0 entirely, in the position of character wheel mint-mark 0 is recessed design, this moment, wheel 20 was surveyed in a position, survey wheel 21 for ten, survey wheel 23 for hundred, kilobit is surveyed wheel 24 and is through on the detection sensing shaft 44, surveyed under the effect of sensing shaft stage clip 25, four recessed places, position that wheel enters character wheel 0 respectively, surveying sensing shaft 44 moves downward, trigger release lever 37, it is invalid to make the self-supporting switch open valve handle 39 twisting, deficiency also just can't spur valve control backguy 40 so that self-supporting switch's balanced lever 38 is in equilibrium state, and valve is in closed condition.
When the user will store the data carrier 34 of the buying tolerance information user data exchange control unit 33 of packing into, after injecting the data input jack of the prepaid gas meter, flow meter that need not working power of the present utility model, the battery of user data exchange control unit 33 gives the central controller in inverted power motor and the speed reduction unit control circuit 27 28 power supplies, this central controller 28 can adopt PIC16C73A, after central controller 28 powers on and stablizes, from data carrier 34, read the user and buy the tolerance data, judge after the legitimacy, with data storage in electric flash memory (can adopt the Flash storer) 29, if data are legal, central controller 28 will drive triode 32 by power motor and utilize external power source to drive inverted power motor and speed reduction unit 26,19 rotations of inverted counting wheel shaft, thereby drive 18 rotations of inverted counter wheel, be subjected to the 18 inner skewed slot effects of inverted counter wheel, inverted counter wheel 18 is to left dislocation, overcome main shaft character wheel retracing spring 17 elastic force, with ten counter wheels 11, hundred counter wheels 12, kilobit counter wheel 13 spurs left, break away from one's carry wheel 14, one's carry wheel 14 is subjected to locating stop piece 15 restrictions, can not move to left.Rotation along with inverted counter wheel 18, ten counter wheels 11 are rotated, ten counter wheels 11 whenever move a numeral, quite import ten cubic metres of tolerance, inverted count detection switch 22 is used for counting, whenever move 11 1 numerals of ten counter wheels, signal of detector switch 22 outputs is given central controller 28, and is reliable to guarantee importing data.After ten counter wheels 11 and counter backward rotation; concave point on ten counter wheels 11 is moved; this moment, ten detection wheels 21 were by jack-up; survey sensing shaft 44 by jack-up; break away from release lever 37; rotate self-supporting switch's handle 39 this moment; self-supporting switch's balanced lever 38 is subjected to release lever 37 effects; to anticlockwise and keep stable; the 38 pulling valve control backguys 40 of self-supporting switch's balanced lever, valve control backguy 40 spurs rotary valve plates 42 by the retracing spring 43 that control guy guard 41 overcomes in the by-pass valve control 4, rotary valve plate 42 rotations; pore on the rotary valve plate is concentric with the pore on the valve 4, and combustion gas is passed through.
After the tolerance data of user's purchase all are converted into oneself wheel demonstration of counter, inverted power motor and speed reduction unit 26 quit work, inverted counting wheel shaft 19 stops the rotation, be subjected to 17 effects of main shaft character wheel retracing spring, ten counter wheels 11, hundred counter wheels 12, kilobit counter wheel 13 returns show the tolerance data of this purchase.
The tolerance purchase data is restricted to ten and multiple, so inverted is ten counter wheels 11, is not using combustion gas to cause error in dipping for counter 5 thereby do not influence the user.
When importing the tolerance data of new purchase in the middle of the user is using, control system with ten counter wheel 11 inverteds of counter 5, surpasses ten buyers automatic carry when inverted automatically.Because of the new purchase volume inverted character wheel of system's basis, therefore can finish the demonstration that adds up of remaining data and new data automatically.
Isolating diode 30 in inverted power motor and the speed reduction unit control circuit 27 is used for isolated data protection electric capacity 31.When system just when the inverted counter is operated; if the user removes power supply or the energy content of battery when being not enough to drive system work; after the P1 mouth of central controller 28 detects, can utilize the energy of protection electric capacity 31 to protect the current data state automatically, treat to continue to finish the inverted operation when powering on once more.
The advantage that the utlity model has is: need not power supply and keep system works, therefore do not exist and disturb and number Unreliable problem according to the problem of losing and battery and voltage detecting circuit existence; With low cost, be fit to large quantities of Amount is applied.
