Description

Computerized magnetic card cost counter for pipeline gas

The computermatic magnetic card taximeter of the utility model metal conduit coal gas field.

Along with the develop rapidly of urban duct coal gas cause, coal gas the user constantly enlarge in recent years, and coal gas fee collection amount is increasing, and coal gas charge at present mostly is to adopt the Payment Methods of tabling look-up behind the first usefulness gas, causes very big financial burden to coal gas company.Looking into gas meter now is to look meter and charge by family with artificial every month each household, brings inconvenience to the user.In order to change this lookup table mode, the domestic development that has devices such as " outdoor type table look-up systems ", but because expense is too high, build difficulty, safeguard numerous and diversely, bring certain difficulty to popularization, this product of current development also all is payment and an artificial lookup table mode behind the first usefulness gas, use wire transmission, bring a lot of problems for construction and protection.Use the device of gas behind a kind of friendship earlier of necessary for this reason development money, with satisfied management and request for utilization.

Goal of the invention of the present utility model overcomes above-mentioned defective exactly, and that invents a kind of payment earlier back usefulness gas counts charging device with computer control automatic look-up table.

The utility model is to realize like this, its architectural feature of accompanying drawings, in order to realize automatic counting, carry out with single-chip microcomputer that data processing constitutes taximeter and solenoid valve is done topworks, form smart instrumentation, its architectural feature is, it partly is made up of the display 4 in bistable electromagnetic operation valve (abbreviation solenoid valve) 1, electromagnetic valve coil 2, control line 3, the taximeter, anti-explosion cover 5, magnetic card input port 6, card reader 7, pipe laying gas port 8 etc., solenoid valve 1 and taximeter all can be contained on the piped gas pipe, see accompanying drawing 1.

In order to realize automatic counting, its architectural feature is, taximeter is by display 9, code translator 10, card reader 11, single chip microcomputer 12, state control circuit 14, electronics gas meter rotational speed converter 15, data-carrier store 16, voltage comparator 17, DC power supply 18 formations such as grade, single-chip microcomputer microcomputer 12 and decoding mouth 10, card reader 11, state control circuit 14, data-carrier store 16 joins, decoding mouth 10 and display 9 join, state control circuit 14 and solenoid valve 13 join, electronics gas meter rotational speed converter 15 and data-carrier store 16 join, voltage comparator 17 and DC power supply 18 join, display 9 can be made up of numeral demonstration and alarm indication a, sees accompanying drawing 2.

The principle of work of the present utility model and the course of work, single-chip microcomputer 12 is under the support of software, be converted into the tolerance value of coal gas after fund data on the magnetic card of putting into card reader 11 are read, be stored in then in the data-carrier store 16, single-chip microcomputer 12 is state of a control control circuit 14 simultaneously, by 1 action of its control electromagnetic valve, " confession ", " breaking " gas control valve are opened or closed automatically, to realize normal air feed or to stop.When the coal gas user uses gas, is electric impulse signal to its gas consumption by electronics gas meter rotational speed converter 15 gas consumption conversion of signals, send into and carry out data processing in the single-chip microcomputer 12, data after the processing will deposit in the data-carrier store 16 data to former storage in and successively decrease, and by display 9 data presentation in the data-carrier store 16 is come out, report to the user.When the data in the data-carrier store 16 are decremented to predetermined value, state control circuit 14 startup warning devices by single-chip microcomputer 12 controls send alarm indication, remind the tolerance that the user purchased to run low, need to buy new magnetic card or pay dues and on the magnetic card of former use, write, at this moment magnetic card is inserted by magnetic card input port 6, taximeter begins operate as normal, guarantees to use continuously gas.When if the data in the data-carrier store 16 are decremented to zero, also input newly purchase or newly write magnetic card the time, go control electromagnetic valve 1 to close source of the gas by the state control circuit 4 of single-chip microcomputer 12 controls and stop air feed.Have only when inserting the magnetic card of new purchase, could start solenoid valve 1 once more and recover normal air feed.Card reader 7 is about to data on the magnetic card and sends in the data-carrier store 16 also " zero clearing ", so that magnetic card can be reused in sense data.In order to prevent to forge the use of magnetic card, on magnetic card and computer equipment, be composed of password and apparatus for security code recognition.The utility model adopts the dc low-voltage mode to power, and be added with anti-explosion cover, solenoid control for, die and adopt noncontacting switch and electronic bistable state mechanical caging mode, with the generation of avoiding electric spark with guarantee the saving power consumption of need not powering when " opening ", " pass " two states.In order to guarantee data-carrier store 16 at the power supply dry cell or when changing battery, can obliterated data, generally on data-carrier store 16, install miniature lithium battery additional.

The utility model is owing to adopt singlechip technology, can realize closing by the air feed control gas piping of paying dues, open function, equipment has self-checking function, has magnetic card charging digital conversion function, changed traditional manual toll collection pattern, having gas leakage reports to the police and explosion-protection equipment, can guarantee the safe gas of using effectively, use the start-stop device of electronic technology control electromagnetic valve door, and leave the output interface of necessity for microcomputer network from now on, when the magnetic card gas consumption reaches lower limit, can remind the user by light warning, need purchase card again or pay and to write card, otherwise, equipment can stop air feed automatically, and characteristics of the present utility model are to use gas after the payment earlier.It is widely used in piped gas air feed field.
