Description
Technical field
The utility model belongs to gas technology, intelligent control technology, reading technique, the field of radio detection technology, more
Body is said, is related to a kind of automatic checkout system of intelligent gas meter.
Background technology
Combustion gas is the important energy source of people's production and living, and gas supply turns into the important composition of countries and cities infrastructure
Part.According to statistics, China was being increased with mouth of making angry, per capita gas consumption and gas pipeline length year by year, in national coal in 2004
Gas total supply is 213.7 billion cubic meters, and natural gas supply total amount is 169.4 billion cubic meters, and liquefied gas total supply is
1122.4 ten thousand tons.City 151 is 277,850,000 people with making angry, and combustion gas popularity rate reaches 81.5%t.From nineteen ninety to 2006, city
City's gas industry supply and demand duct length adds nearly 7 times, increases to 18.9 ten thousand km from 2.4 ten thousand km.Especially at 2002 to 2006
Year, average growth rate is more than 13%, and wherein the average growth rate of natural gas line is then more than 20%.Gas meter, flow meter-managed as city
The metering device of road combustion gas, it is indispensable.The development of combustion gas industry has driven the development of gas meter, flow meter.
Country had promulgated that some policies increased the investment to natural gas related industry in recent years, and west was started since 2000
After the defeated engineering in gas east, line two wires area successively penetrates, and puts into production, and three lines then started to build on October 16th, 2012,
It is expected that it will be built successfully in 2015.In addition.Foundation of the country to marine liquefied natural gas passage also takes much count of, so, naturally
Gas will improve constantly in the dominant role of China's gas industry.By 2015, China's natural gas demand will turn over one than 2008
Kind, reach 2600 billion cubic meters；To the year two thousand twenty, the growth rate of Natural Gas Demand will be slowed down, but will be kept for year within 2016
Equal 8% growth rate, to the year two thousand twenty, the demand of natural gas is expected to more than 4000 billion cubic meters.
In addition, Urbanization Process In China is accelerated, urban population is continuously increased, and this can all excite work to use and civilian outstanding to combustion gas
It is the rising of natural gas demand, combustion gas and gas meter, flow meter industry is kept rapid growth momentum.
With the fast development of the communication technology, computer technology and automated control technology, daily life becomes
Technicalization, intelligentize and informatization.People are to the demand more and more higher of gas meter, flow meter, therefore as intelligent gas meter manufacturer,
It is imperative that the raising quality of production and efficiency can be described as.The quality of gas meter, flow meter depends on the matter of all parts of composition gas meter, flow meter
In the case that amount, only all parts are good, the gas meter, flow meter for meeting user's request can be just produced.The core component of gas meter, flow meter
Including parts such as LCDs, valve, wireless module, IC-cards, former detection designs one just in each module
Individual detection means, or even the product of a module different model also have different detection means, such as LCD MODULE, intelligence
Gas meter, flow meter Panel Type is different, and detection means is also different, and so often detecting a kind of liquid crystal display of model will change the outfit again
Put, not only lost time but also waste of manpower, substantially reduce operating efficiency.
Nowadays, the test technique automatic in gas meter, flow meter production is not still intelligent gas that is very ripe, producing
Table still suffers from the problem of big and small, and through investigation, statistics and analysis, the problem of gas meter, flow meter being applied in user is present is main
Have：
1), open and close valve performance is unstable, and part is influenceed excessive by humidity, temperature in valve, and service life is short, Er Qiejing
The situation for being not related to valve or not driving valve often occurs；
2), because deck service life is shorter, cause controller can not normal data in identification card, it is necessary to change control
Device；
3) it is lack of standardization due to plugging, because IC-card itself can not identify the data of read-write and storage exactly, easily cause
Data corruption in card, so, the situation that actual amount is not consistent with user's purchase tolerance usually occurs；
4), the sealing of controller is poor, and in the space higher in temperature and humidity, connecing for battery often occurs
Situations such as contact corrosion, sensor and controller tie point aoxidize, can not normally start controller；
5), power consumption is bigger, and some users, which change one-shot battery, can only use a week；
6), IC-card intelligent gas meter scientific and technological content is higher, and having some users can not be proper use of, such as sometimes by IC-card
It is anti-inserted, cause normally to supply；
7), compared with general gas table, IC-card gas meter, flow meter has metering and control function concurrently, but hiding trouble point also compared with
More, certain point is broken down, and just can not normally be started controller, will be directly affected user's food problem.
In current information-intensive society, continuous development and wound with computer technology, automated control technology and the communication technology
Newly, people are to the demand of intelligent gas meter also more and more higher, therefore as intelligent gas meter manufacturer, improve the quality of production and
Efficiency is imperative.The quality of gas meter, flow meter depends on the quality of all parts of composition gas meter, flow meter, and only all parts are good
In the case of, it can just produce the gas meter, flow meter for meeting user's request.The core component of gas meter, flow meter include LCDs, valve,
The parts such as wireless module, IC-card, former detection design a detection means, or even a mould just in each module
The product of block different model also has different detection means, such as a LCD MODULE, and intelligent gas meter Panel Type is each
Different, detection means is also different, so often detect a kind of liquid crystal display of model will changing device again, not only lose time but also waste people
Power, substantially reduce operating efficiency.
