Description
The utility model relates to a kind of step-by-step counter of mechano-electronic fabricated structure, is used for fields such as coal gas, tap water, electric current metering, can realize continuous compound reading effect, belongs to mechano-electronic measuring instrument field.
The existing counter that is used for metering effects such as coal gas, tap water, electric current mainly contains mechanical type step-by-step counter, mechanical type coding counter and electronic counter etc.The mechanical type step-by-step counter is divided into multiple structure type again by its type of drive difference, but its basic function all is the mechanical action frequency of record, directly shows the numerical value that is measured by the decimal system with number in window again, is called window value; The weak point of this counting mode is not supply to read its window value with the method for electronics with the corresponding electric signal output of decimal system window value.The mechanical type coding counter then adopts four switches to carry out the break-make combination, represents ten natural numerical value of 0-9 respectively, and its window value is corresponding with switch combination, reads the assembled state of four switches with the method for electronics and just can read its window value; Its shortcoming is that one is that its switch is a switch with mechanical contact, and the driving force that needs is big; The 2nd, though can be combined into metric any position as required, each all is independently, does not reach the function of stepping, and promptly low level walked for ten steps, and a high position makes a move; The 3rd, its data output has only parallel a kind of mode.End is got up, and existing counter is because design and structural reason, the ubiquity complex structure, and the counting degree of accuracy is low, and the reading inconvenience especially can not realize the shortcomings such as effect of multi-metering.
Goal of the invention of the present utility model is to overcome the shortcoming of existing electronics, the existence of mechanical counter technology, seek on the physical construction basis, counter to be improved, design forms a kind of existing window value tens digit and shows, the output of electronics serial code is arranged again, and serial code has the electrical distance transmitting step-by-step counter of anti-interference effectiveness.
In order to realize the foregoing invention purpose, the utility model improves on the existing conventional mechanical counter basis of containing parts such as several wheel drive mechanisms and fixed support, install the infrared exoelectron code switch respectively additional in 0.1 consecutive number wheel gap of taking turns to hundred figure places of mechanical counter, the infrared exoelectron code switch adopts the infrared sending and receiving of through mode that pipe is formed; On the platen surface of circular number wheel, waiting on the central angle radius and be shaped on light hole respectively on the different radii circumference around center pit, its layout is corresponding with " 8421 " coding, promptly when the number wheel rotated a week, its light transmission state was corresponding with the binary digit of " 8421 " sign indicating number of " 0-9 " tens digit.Gear train is with the rotation requirement according to a certain percentage of measured parameter, 0.1 figure place wheel is rotated, after it rotates a circle, make the units wheel rotate one, after the units wheel rotates a circle, make the tens wheel rotate one, and the like, just read decimal numerical value respectively at the window mouth.Simultaneously, when number wheel is mobile, because that the light hole on the number wheel causes is luminous with to receive the on off operating mode that light cooperates just in time corresponding with the number combination, and through the usefulness of processing of circuit realization electronic counting.
It is feasible that the utility model compared with prior art has design concept, stable and reliable for performance, machinery and the dual reading degree of accuracy of electronics advantages of higher, and electronical reading is not subjected to power and influences, and can realize the function of global enumeration.
Fig. 1 is number wheel of the present utility model and infrared switch mounting structure synoptic diagram.
Fig. 2 is number wheel light hole layout and 8421 yards corresponding relation synoptic diagram.
Fig. 3 is a signal Processing electricity principle schematic.
Embodiment of the present utility model adds the electronic counting function to form the electrical distance transmitting step-by-step counter integral body that has machinery, the dual counting of electronics and do not powered and influence on existing mechanical counter basis, the realization of its electronic counting function realizes that by taking turns at number to offer light hole and add system infrared exoelectron code switch between the number wheel signal that is produced by the electronic code switch gets final product reading through the data acquisition unit processing.The infrared exoelectron code switch places between the gap of number wheel, in the middle of it is expelling plate, both sides are dash receiver, read individual, ten double figures like this, if read three figure places, then the plate between 0.1 figure place wheel and the units wheel is an expelling plate, and the plate between units wheel and the tens wheel is the sending and receiving plate, and the face of promptly close units wheel is for sending out; In like manner the plate between tens wheel and hundred figure places wheel also is the sending and receiving plate, and the face that promptly close tens is taken turns is for receiving, and the face of taking turns near hundred figure places is to send out.Between hundred figure places wheel and thousands digit wheel, place dash receiver at last.Read other figure place, its principle is identical, and promptly two ends are respectively single-shot, single plate of receiving, and middle is the sending and receiving common plate.
On the platen surface of each circular number wheel 17, waiting and be shaped on a plurality of light holes 13 on the central angle radius on the different radii circumference respectively around center pit 18, wherein 18 nearest " 8 " sign indicating numbers encircle on 12 and are shaped on 2 light holes in the decentering hole, on " 4 " sign indicating number ring 11, be shaped on 4 light holes, on " 2 yards " ring 10, be shaped on 4 light holes, on " 1 " sign indicating number ring 9, be shaped on 4 light holes.Evenly distributed right-to-left totally 5 numbers wheel between fixed mount 2, its rightmost is 0.1 a figure place wheel 3, is followed successively by units wheel 4, tens wheel 5, hundred figure places wheel 6 and thousands digit wheel 7, is shaped on infrared exoelectron code switch 8 by designing requirement in the crack between each number wheel.Gear train 1 belongs to the conventional structure of existing machinery counter.
Infrared exoelectron code switch 14 is to be combined by electrical connections such as resistance R, light emitting diode D, transistor Q and number wheels 17, be be arranged in parallel 12 (one of each of the two ends of only drawing in its schematic diagram) altogether, its light emitting diode D is an infrared emission, transistor Q is infrared reception, the resistance value of connecting with two utmost point D is generally 4-6K, resistance value on transistor Q collector is 480-550K, and integrated chip 16 is chosen the parallel/serial coding of PT2262 type IC, its A
