Abstract

The utility model relates to a counter. An opaque shading film is fixed on the side of each counting gear of a gas meter. Five light holes are distributed on each shading film evenly. Circuit boards controlled by transistors are mounted on two sides of each shading film respectively. Luminotrons on an emitting board on one side of each circuit board emit light when powered on. A receiving board on the other side of each circuit board is used for receiving light and generating corresponding level signals. A processor is used for sequentially controlling the luminotrons to emit light, receiving the level signals returned by the receiving board, and converting the signals into decimal data through binary encoding; and the data are actual data on character wheels of the gas meter. Thus, the counter can display the data on the character wheels accurately, and accuracy is high.

Description

Counter

Technical field

The utility model relates to a kind of counter.

Background technology

At present, gas meter, flow meter can add up other gas consumption of each household automatically, in order to can pay the fees according to the cubic meter number that consumed combustion gas in every month, but because the accuracy of counter is relatively poor, so be easy to make mistakes, causes the user accurately not pay the fees.Most of direct-reading gas meter, flow meters have all adopted magnetic-pulse formula counting, namely be stained with magnet steel at character wheel, at the other steel spring pipe of placing of magnet steel, when magnet steel during near the steel spring pipe, umber of pulse is once calculated in its adhesive, the maximum characteristics of these tables are that diamagnetism is poor, and steel spring pipe magnetization afterpulse is forbidden to cause counting inaccurate.

Summary of the invention

The purpose of this utility model is in order to overcome above deficiency, and a kind of simple in structure, counter that the data read accuracy is high is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of counter, comprise fixed support, fixed support is provided with the character wheel of seven series connection, seven character wheels comprise four counting character wheels and three sub-character wheels, the both sides of each counting character wheel are provided with anti-dazzling screen, be evenly distributed with five light holes on each anti-dazzling screen, five light holes are equally distributed on the same circumference, the outside that is arranged on outermost two anti-dazzling screens is equipped with circuit board, also be provided with circuit board between all the other per two adjacent anti-dazzling screens, the one side of each circuit board is expelling plate, the another side of each circuit board is dash receiver, expelling plate and dash receiver are oppositely arranged, be evenly distributed with five luminotrons on the expelling plate, five luminotrons are equally distributed on the same circumference, and circuit board links to each other with main circuit board, main circuit board links to each other with wireless module, and wireless module links to each other by signal with processor.

The utility model compared with prior art has the following advantages:

During counting, power valve on the expelling plate is all luminous, receiving tube on the receiver sheet receives simultaneously, when certain to T-R tube and the light tank of counting on the character wheel over against the time, T-R tube receives light signal, produce a high level then to processor, it is luminous and gather the level signal that dash receiver returns simultaneously that processor is controlled power valve successively, this signal carried out converting metric data to after the binary coding then, like this, counter just can show the data on the character wheel, accuracy height exactly.

Show a kind of counter of the utility model as Fig. 1 to Fig. 3, comprise fixed support 1, fixed support 1 is provided with the character wheel of seven series connection, seven character wheels comprise four counting character wheels 2 and three sub-character wheels 3, the both sides of each counting character wheel 2 are provided with anti-dazzling screen 4, be evenly distributed with five light holes 5 on each anti-dazzling screen 4, five light holes 5 are equally distributed on the same circumference, be that angle between per two light holes is 72 °, the outside that is arranged on outermost two anti-dazzling screens 4 is equipped with circuit board 6, also be provided with circuit board 6 between all the other per two adjacent anti-dazzling screens 4, the one side of each circuit board 6 is expelling plate, the another side of each circuit board 6 is dash receiver, and expelling plate and dash receiver are oppositely arranged, and is evenly distributed with five luminotrons 7 on the expelling plate, five luminotrons 7 are equally distributed on the same circumference, circuit board 6 links to each other with main circuit board 8, and main circuit board 8 links to each other with wireless module 9, and wireless module 9 links to each other by signal with processor.

The principle of the character wheel identification in a kind of counter:

The disposal route of individual position coding: the coding of individual position is once to identify every 0.5, such 0～9 just has 20 kinds of different codings, table 1 is actual coding schedule, wherein high level 1 representative is bright, low level 0 representative is gone out, whenever occur 0.5,1.5 ... 9.5 when coding does to be 0,1 ... 9 handle, and a position initial coding just disposes like this;

Table 1 is the coding codeword table:

?	D5	D4	D3	D2	D1	Coding
