Description

The coding counting assembly of series connection output

Technical field

The present invention relates to a kind of counting assembly, relate in particular to a kind of coding counting assembly that can be used for the series connection output of measuring instruments such as water meter, ammeter, gas meter.

Background technology

The passive type counting assembly that is used for measuring instruments such as water meter, ammeter, gas meter at present adopts one group of way of output in parallel of exporting of a character wheel more, as: as described among the Chinese patent 01112371.0.00105255.1.There is a common defective in this way of output, that is: each character wheel all is provided with one group of output terminal, the mode of this multidigit character wheel output in parallel not only circuit increase, connect up complexity, take a plurality of ports of computing machine, and the trouble spot is many, versatility is poor, carry is put easy error code etc., and the practical application of checking meter to computing machine has caused very big obstacle.

Summary of the invention

Purpose of the present invention be exactly many for the counting assembly outlet line that solves present gauge, take port many, safeguard that difficult, obstructed usefulness and carry place are prone to problems such as error code, provide a kind of and have simple in structurely, the coding counting assembly that the series connection of advantages such as can effectively reducing outlet line, reduce to check port, increase its versatility, carry point is judged error correction is exported.

For achieving the above object, the present invention adopts following technical scheme:

A kind of coding counting assembly of the output of connecting, it is made up of the count word wheel of the different unit quantities of a plurality of correspondences, the code-disc of the corresponding unit quantity of expression is housed in each counting character wheel, the resistive segments of a plurality of adjacency of setting-in of rule on the code-disc circumference, on the code-disc internal perisporium, be provided with simultaneously can move along circumferential wall and with the contacted brush of each resistive segments, output lead on brush and each resistive segments, each resistive segments in described each counting character wheel is connected in series, the one end is an output terminal, and brush is as another output terminal; The output terminal of resistance in series section is connected with the brush of a last counting character wheel then, corresponding brush then connects with the output terminal of next resistance in series section.

The digital corresponding circumferential position of on the described code-disc each is embedded with the resistive segments of different resistances.

Described each resistive segments is divided into preceding half section and second half section, and its resistance difference.

Described counting character wheel is by the order series connection of a position, little-endians such as ten, hundred and arrange, and the setting principle of the resistance of resistive segments is in wherein every bit code dish: the maximal value of the resistance value in low is the minimum value of the resistance value among the Gao Yiwei; Simultaneously the minimum change value of resistance value is the maximal value of the resistance in low one in high one.

The present invention with the series connection back of the resistance in counter wheel reading, can determine counting according to the total resistance value of gained with the series connection form, thereby has avoided present character wheel to adopt parallel way output to cause interface too much, is difficult to guarantee accuracy of reading, and problem such as failure rate height.

The invention has the beneficial effects as follows: by above design, just every character wheel is passed through resistance code-disc separately, promptly independent separately series connection again is combined togather uniformly.Result after the series connection addition is translated into corresponding former code data, has just obtained the metering numerical value of our needed water, electricity, gas instrument.Promptly do not need supply power during this, do not need computer operation yet, this counting assembly is writing down numerical value automatically, people only need measure tandem data just when wanting to read this numerical value, it is simple in structure, easy to use, saved the interface resource and the working time of computing machine to greatest extent.

Embodiment

The invention will be further described below in conjunction with accompanying drawing and embodiment.

Among Fig. 1,2, a kind of coding counting assembly of the output of connecting, it comprises that print wheel shaft 2 and inside mounted thereto are provided with the character wheel 1 of resistance code-disc 4.

Among Fig. 3 a-3b, each counts character wheel 1 corresponding corresponding unit quantity, a position as shown in Fig. 3 c, shown in Fig. 3 b ten, shown in Fig. 3 a hundred etc., the code-disc 4 of the corresponding unit quantity of expression is housed in each counting character wheel 1, the resistive segments 5 of a plurality of adjacency of setting-in of rule on code-disc 4 circumference, on code-disc 4 internal perisporiums, be provided with simultaneously can move along circumferential wall and with each resistive segments 5 contacted brushes 6, output lead 3 on brush 6 and each resistive segments 5, each resistive segments 5 in each counting character wheel 1 is connected in series, the one end is an output terminal, and brush 6 is as another output terminal; The output terminal of resistance in series section is connected with the brush of a last counting character wheel, corresponding brush is then connected with the output terminal of next resistance in series section.

In order to make non-overlapping copies, staggered mutually after the resistance value series connection addition in every character wheel code-disc, forms one and be convenient to the numerical value accurately deciphered.Carried out orderly arrangement in the resistance setting of resistive segments 5, its setting principle is: ... hundred, ten, resistive segments 5 resistances of individual position are minimum value (5K) in high one (ten) by the maximal value (5K) in low (as individual position) ... analogize in proper order.Simultaneously the minimum change value (as the 5K in ten character wheels of Fig. 3 b) in high also is the maximal value (as the 5K in the character wheel of individual position) in low.

For fear of making a low character wheel code-disc change the critical mistake that a full circle upwards produces because of the out of true of mechanical location during a carry, specially each digital resistive segments 5 of a high character wheel code-disc 4 is divided into preceding half section and second half section (as 35K and the 40K in ten character wheels of Fig. 3 b), be at the brush 6 of a low bit code dish 4 like this and refer to 9 when still being 0 critical place, just can refer at preceding half section still to be the second half section to go to judge actual right position, thereby avoid error code by high one brush 6.

In instrumentation (rotation) process, resistive segments 5 contacts and does with brush 6 and relatively rotates, make and form the resistance value that constantly changes between resistive segments 5 and the brush 6, output after this resistance value is connected successively by the lead 3 among Fig. 1, Fig. 2, form a plurality of resistive segments 5 additions resistance total value afterwards, this value has just obtained our needed metering numerical value after deciphering by computing machine.For example: the maximum value 5K among Fig. 3 c in the character wheel of position is as minimum resistance 5K in ten character wheels among Fig. 3 b; Maximum value 100K is as hundred minimum resistance 100K among Fig. 3 a in ten ...According to the character wheel running status of Fig. 3 a-3c, the resistance of pointer this moment (brush) on hundred, ten, individual relevant position is respectively 300K, 40K, 4K, and the result of its series connection is 300K+40K+4K=344K, and corresponding number is exactly 137 in Fig. 3 a-3c.

This shows, the design of the present invention aspect resistance, well arranged when making different character wheel resistance connect addition, folded and not random, corresponding one by one with the character wheel number, be convenient to very much computing machine decoding.
