Description
Technical field
The utility model relates to a kind of counter, and especially a kind of electromechanical integration counter that increases photoconductive structure on the mechanical counter basis belongs to the measuring instrument Instrument technology field.
Background technology
The present stage people adopt machinery or two kinds of metering methods of electronics usually to the metering of doing fluid motion and doing other moving object.Mechanical system mainly is by the character wheel carry counting system; The sample circuit that the electronic technology mode mainly is made of sensor is measured various types of displacements and variable, handles back output as calculated and shows.The advantage of mechanical system metering is dependable performance, do not need power supply, can use in rugged surroundings, cost is low, and shortcoming is the on-the-spot reading of data of needs, function singleness; The advantage that the electronics mode is measured is diverse in function, can realizes remote reading and monitoring that shortcoming is that cost is higher, maintenance is big, reliability relies on power supply and Circuits System fully.In order to learn from other's strong points to offset one's weaknesses, the metering method that machinery and electronics combine has appearred, and this mode generally is to increase electronic structure on mechanical character wheel counter.But understand according to the applicant, in the counter of existing dynamo-electric combination, the electronic component quantity that is increased is more, such as at decimal system mechanical character wheel when the improvement that do to increase photoelectric sensor, therefore the photoelectric sensor quantity that is increased need the signal of processing also many, corresponding circuit complexity all more than five groups, and because number of sensors is many, the position of the corresponding character wheel loaded down with trivial details inconvenience that when laying, seems.
Summary of the invention
The purpose of this utility model is: at the weak point that above prior art exists, propose a kind of machinery and electronics metering advantage and electromechanical integration counter simple in structure of having concurrently.
In order to reach above purpose, electromechanical integration counter of the present utility model comprises that the infrared transmission that the center is worn the anti-dazzling screen that is connected with axle and rotating character wheel, is fixed on the character wheel circumference, is installed in the anti-dazzling screen both sides and is electrically connected on the signal transmission board receives pipe, and described infrared transmission receives the pipe relative fixed.Its improvements are, it is right to Guan Weisi that described infrared transmission receives, and wherein three pairs with central angle adjacent the arranging of 36 degree at interval, and another differs 180 degree to one of centre with described three centerings with center of circle angle and arranges; Anti-dazzling screen on the described character wheel is five, wherein four with four pairs of infrared transmissions receive the pipe arrangement mode identical, another with above-mentioned four in the anti-dazzling screen arranged separately differ 36 with central angle and spend adjacent arranging.Like this, anti-dazzling screen receives passing the slit in the middle of managing from infrared transmission when rotating with character wheel, and encoding law that can be specific realizes the recognition of decimal system number of words with the scale-of-two sensing mode.
The utility model has reduced main electron device quantity, has simplified the structure by the ingenious layout to existing electromechanical integration counter sensor spare position, thus the progress that has brought existing electromechanical integration counter.

Below in conjunction with accompanying drawing the utility model is further described.
Embodiment
Embodiment one
The counter of present embodiment comprises that mainly the center wears the anti-dazzling screen 2 that is connected with axle 5 and rotating character wheel 1, is fixed on character wheel 1 circumference, is installed in infrared transmission that anti-dazzling screen 2 both sides are electrically connected on signal transmission board 4 and receives managing 3, infrared transmission receive to manage 3 with character wheel central shaft relative fixed.Totally three pairs of character wheels 1 are represented individual, ten, hundred decimal system counting (in case of necessity, can increase character wheel 1 as required and be used for more high-order counting) respectively.Anti-dazzling screen 2 on each character wheel is five, and it is four pairs that infrared transmission receives managing 3.Infrared transmission receives pipe and anti-dazzling screen with around arranging with the mode of character wheel concentric circumferences: 1. the four pairs of infrared transmissions receive that 36 degree are adjacently arranged at interval, another arranges to then differing 180 degree with center of circle angles in centre of above-mentioned three centerings with central angle to managing three couple in 3; In five anti-dazzling screens 2 four and four pairs of infrared transmissions receive that 3 arrangement modes are identical to managing, another anti-dazzling screen with above-mentioned four in independent anti-dazzling screen differ 36 with central angle and spend adjacent arranging.Like this, anti-dazzling screen 2 passes managing the slit in the middle of 3 from infrared transmission reception with character wheel 1 rotation the time.Character wheel 1 circumference is divided into ten five equilibriums, and the numeral of correspondence position is 10 bit digital from 0～9.Infrared emission receives managing 3 as incorporate infrared light transducer[sensor.
Five anti-dazzling screens 2 and the four pairs of infrared emission receive and rearrange a collecting unit to managing 3 by above-mentioned ad hoc fashion, this collecting unit can be finished the identification to ten kinds of location statuss of a character wheel 0-9, its basic functional principle is: when character wheel 1 rotation, the anti-dazzling screen group 2 that is connected on character wheel 1 outer circumference is followed character wheel 1 and is done rotation synchronously, character wheel 1 every generation one-bit digital changes, the relative infrared emission in anti-dazzling screen 2 positions receives and just takes place once to change to managing 3 positions, when an anti-dazzling screen 2 be parked in owing to the character wheel carry infrared emission receive the slit of managing 3 centre in the time, infrared emission receives and to be stopped a receiving tube output terminal output low level " 0 " by anti-dazzling screen 2 to managing the infrared beam that 3 power valve sends; Otherwise, when anti-dazzling screen 2 is not in infrared emission receives the slit of managing 3 centre, a receiving tube output terminal output high level " 1 ".Like this, five anti-dazzling screens 2 are along with character wheel 1 rotation carry receives managing 3 in four infrared emission of different periods blocking-up respectively, make four infrared emission receiving tubes 3 export corresponding blocking-up low level " 0 " respectively and do not block high level " 1 ".Anti-dazzling screen 2 revolve turn around after, export 10 groups of mutually different binary codes respectively by four infrared emission receiving tubes 3, receive the circuit structure that pipe is connected with infrared emission this code is deciphered by above-mentioned true value numerical table, can read and show corresponding character wheel true value numeral.The true value number of binary code correspondence sees Table one.
