Abstract
The utility model relates to an electronic digital reading mechanical rotating wheel counter. Each digital wheel of a decimal system counter is provided with four switching quantity type sensors; each digital lattice at the periphery of the digital wheels is respectively coated with light-absorbing material or light-reflecting material according to definite regulations; or magnetic material or magnetic induction material is arranged on parts of lattices. Through the judgment of the sensors to the positions of the digital wheels, a standard digital waveform is obtained after signals sensed by each row of sensors are shaped and processed; after the waveform is conveyed to a single-chip computer to process, the digital recognition of the digital wheels is realized.
Description
The utility model relates to a kind of counter.
Mechanical rotary-type counter is widely used on ammeter (individual calling register), gas meter, mileometer and other accumulative total formula measuring instrument, simple in structure and reliable operation is stablized owing to it, in period, all is an irreplaceable metering method at suitable phase of history.Yet, because the development of technology, require this gauging instrument to export the metering result in the electronic digitalizing mode, so that remote transmission or directly deliver to computer and carry out data processing in addition, thereby and this class instrument owing to there is not corresponding electronic digitalizing output device to bring significant problem to metering automation.Digitizing for this kind equipment, current solutions is to carry out digitized processing by the pulsed counting, promptly by the number of revolutions of a certain rotatable parts of this instrument is carried out pulse output metering by light, magnetic or resonant inducing mode etc., revolution is moving once just to be exported a pulse or pulsegroup and carries out digitized processing by one-chip computer again and added up and store.There is following shortcoming in this mode:
One, this pulse digit mode is not to read the metering result on measuring instrument, but carries out the electronic type metering again, like this, has just formed and carried out double metering (being original mechanical type metering and additional pulsed metering) on same instrument.The electronic digit of being exported not is the metering result of former instrument, but the result of additional electron metering.
Two, the electronics metering method is subject to disturb, as thunder and lightning, power-supply fluctuation and various power current to interference of circuit or the like, thereby the accuracy of influence metering.And disturbed each time among all permanent result who is present in metering of the mistake metering that is produced, in other words, the metering mistake can accumulate.
Three, must carry out end number of degrees initialization process.Because the just metering of process of pulsed metering, its final metering must be transferred to computing machine (or single-chip microcomputer) and handle and store, so degree was handled at the bottom of each measuring instrument all need carry out electronization.This in many cases (when installing) as large quantities of watt-hour meter be very inconvenient.
Four, pulse metering device must guarantee in the overall process of metering in running order all the time, some measuring instruments are (as watt-hour meter, water meter, the gas meters etc.) that are in free of discontinuities work year in year out, the corresponding pulses measuring apparatus is continuous working accordingly also, therefore produced two problems: 1. corresponding electronic device must guarantee long-term substantially error-free work continuously, otherwise its metering result has very big discrepancy; 2. long-term continuous working produces the life problems of device inevitably, and particularly sensor is especially true.
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of mechanical rotary-type counter of realizing that electronic digitalizing reads is provided.
The scheme that the utility model purpose realizes is: the periphery that will have each digital wheel of decimal counter now is divided into ten lattice, represent 0,1,2,3,4,5,6,7,8,9 respectively, each lattice is coated light absorbent or reflectorized material respectively by certain rule, or each digital wheel utilizes external structure to fix four switch volume sensors (sensor that promptly only reflects 0,1 state) by certain rule device magnetic material or magnetic induction material on partitive case at each a certain position of digital wheel periphery.When digital wheel is in diverse location, four states that sensor reflected of one row have nothing in common with each other, and the signal that is come out by each biographies sensor sensing of counter that the several number code wheel is formed is handled the digital waveform of the standard that obtains through shaping, and this waveform is delivered to one-chip computer through output and handled and realize that just electronic digitalizing reads.
The sensor of the utility model indication is photo-electric or magnetic inductive or inductance type (being resonant mode).
Usually mechanical counter is to be made of 4-8 digital wheel, and the centre is connected with rounding wheel, constitutes the decimal counter of a 4-8 position.The utility model need be arranged the sensor array of corresponding (4-8) * 4 equally, and each row (4) sensor is responsible for the digit recognition of a digital wheel.How many biographies sensors what digital wheels need.
The utility model adopts four Boolean value output sensors to discern digital rotary wheel device, and then realizes that electronics directly reads the method for numeral, is not subject to the interference of factors such as thunder and lightning, power-supply fluctuation, the accuracy height, easy to use, the life-span is long, more can not produce the history accumulation of mistake metering.
Below in conjunction with embodiment the utility model is further described.
Fig. 1 is the utility model timer number wheel radial diagrammatic cross-section.
Embodiment 1:
As shown in Figure 1, the upper fixed at each digital wheel 1 of counter has 4 reflective photoelectricity that only reflect 0,1 state to tube sensor 2.Digital wheel 1 periphery is divided into 10 lattice, represents 0,1,2,3,4,5,6,7,8,9 respectively, and every lattice are coated black (light absorbent) by mode shown in Figure 1 at 1,3,6,7 lattice, all the other each lattice coated white (reflectorized material).When a certain lattice when being white (light reflex time), the state of sensor 2 is 1, is 0 when black.Digital wheel 1 revolution moves lattice, and corresponding variation all takes place the state of sensor.In addition the position is corresponding one by one with the reading of eye-observation, just realizes the reading of digital wheel 1 is become the judgement of logarithm code wheel 1 position, and its result is as shown in the table:
Obviously, the shown state of each sensor is to be convenient to very much electronic digital processing.The signal that every biographies sensor sensing is come out only needs the square wave digital waveform of the standard that just can obtain by simple shaping.The waveform that each biographies sensor is exported only need be delivered to one-chip computer and carry out the digit recognition process that simple process has just been finished a digital wheel.
