Description
Technical field
The utility model belongs to the instrument field, particularly a kind of gas meter, flow meter.
Background technology
Gas meter, flow meter is a kind of metering device that is used for the metering gas use amount.Common gas meter, flow meter connected mode is that an end connects gas pipeline, and the other end is connected on the kitchen range, and when the user used combustion gas, combustion gas entered kitchen range from gas pipeline through gas meter, flow meter, connecting tube; Pre-aeration quantity IC-card diaphragm gas meter commonly used is by being arranged on mechanical type meter and the Hall counter in the gas meter, flow meter to the metering of using combustion gas, be that mechanical counter of gear train drive that combustion gas promotes to be arranged on through gas meter, flow meter the time in the gas meter, flow meter is beated, when combustion gas stops to flow, counter also stops to beat, and finally is to determine what of gas consumption by the numeral of the demonstration on the counter.Respond to the flow of mechanical counter simultaneously by Hall element, determine to make gas consumption, the corresponding gas consumption of deduction from the tolerance that the user buys, but this gas meter, flow meter has following shortcoming: the price that at first is combustion gas does not remain unchanged, need change according to the purchasing price of gas company, if the user buys tolerance and does not use up price and change, still buy the price on the same day during use, so just cause gas company to buy in the combustion gas price and sell the unmatched situation of combustion gas price, may be unable to make ends meet, produce heavy losses.Be exactly that the user may be because price be an integer when buying tolerance in addition, the amount of money of buying certain tolerance is not integer, brings the trouble that converts or change.
Summary of the invention
The utility model provides the amount of money formula gas meter, flow meter of a kind of preliminary filling amount of money value, adaptation combustion gas price change at the problems referred to above.
The technical solution of the utility model is: a kind of prepayment diaphragm gas meter, comprise power supply, main control module, main control module connects gage probe, data-carrier store, the IC-card read-write interface, display module and valve driving module, power supply is used for powering to main control module, the data on flows that gage probe is used to gather combustion gas sends main control module to, be transported to after the main control module deal with data in the display module show and data-carrier store in store, main control module is according to the switch of data processed result by-pass valve control driver module driving valve, and described main control module also is connected with and is used to change the price modification card read-write interface that combustion gas is chargeed.
As preferably, described gage probe is a Hall element.
As preferably, described main control module is connected with the gas-robbery resistence module, and the gas-robbery resistence module is connected with gage probe.
As preferably, described main control module is connected with warning device, is used to point out the user's gas table to occur supplementing with money unusually and in time.
As preferably, described main control module is connected with voltage detection module, and voltage detection module connects power supply, is used to detect power source voltage.
As preferably, described display module adopts LCDs.
As preferably, described main control module connects the super capacitor as standby power supply.
Principle of work of the present utility model is: after the user hands over money, institute's amount of money of purchasing and combustion gas price data are written in the card, the user inserts IC-card in the controller on the gas meter, flow meter again, card can take out, the amount of money of input gas meter, flow meter controller internal memory is reduced (amount deducted=gas consumption * price) automatically during with gas; When the combustion gas price changes, gas company is reset the combustion gas price with special-purpose price modification card for each user, the price modification card read-write interface of price modification card insertion gas meter, flow meter, gas meter, flow meter is by the combustion gas charging unit price of the price modification information change data-carrier store stored on the read-write price modification card; When remaining sum in the table during less than the warning amount of money set in advance, provide audible alarm, point out the user in time to supplement with money; When remaining sum is zero, valve-off, the user supplements plug-in card again with money and opens valve gas.The utility model can conveniently be adjusted the price of combustion gas, can not cause gas company to buy in the combustion gas price and sells the unmatched situation of combustion gas price.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
As shown in Figure 1, it is Hall element that main control module connects gage probe, is used to gather the data on flows of combustion gas, and the combustion gas price of storing in this data on flows and the gas meter, flow meter multiplies each other and obtains the amount of money that the user uses, and deducts from user balance.This module connects the gas-robbery resistence module simultaneously, when the user steals gas by stoping gas meter, flow meter to rotate with the close gas meter, flow meter of magnet, occur unusual because of the conducting simultaneously of Hall element two terminal circuits, and send abnormal signal to main control module, the hummer that main control module detects unusual back control warning device sends warning, and sending the pass valve signal simultaneously to the valve driving module, by-pass valve control is closed breather line, stops air feed.
Power supply is powered to main control module by battery, and main control module is by remaining sum and other flows of liquid crystal display explicit user, information such as warning.
Main control module connects data memory, data memory adopts eeprom memory, is used for various gas meter, flow meter information and user profile such as storing subscriber information data, table number information, measuring parameter information, combustion gas pricing information, use information, abnormal alarm information.
Main control module connects alarm module, and when gas meter, flow meter takes place when unusual, or power down or storage tolerance are sent buzzer warning sound, call user's attention when not enough.
Main control module connects the IC-card read-write interface, the IC-card read-write interface is used for IC-card and gas meter, flow meter carries out the information transmission, the user can pay the combustion gas expense in advance by gas company, gas company writes the information of paying the fees to IC-card then, the user realizes the break-make of combustion gas by IC-card and gas meter, flow meter message exchange, thereby realizes the pre paid functionality of gas meter, flow meter.When the combustion gas price changed, gas company was by gas meter, flow meter message exchange realization the resetting combustion gas price of price modification card with each user; The price modification card read-write interface of price modification card insertion gas meter, flow meter, gas meter, flow meter reaches the purpose of accurate billing thus by the combustion gas charging unit price of the price modification information change data-carrier store stored on the read-write price modification card.
Main control module connects the voltage detection module that is used to detect supply voltage; Voltage detection module detects power source voltage, when supply voltage drops to under-voltage value, send under-voltage signal and give main control module, main control module sends alarm command, valve closing order, data storage command and stops the IC-card read write command, and each functional module is according to command execution.
Main control module connects the super capacitor as standby power supply; Behind power supply power-fail, adopt standby super capacitor power supply, be mainly used in the command execution of main control module order issue and each performance element this moment.
Be connected with the valve driving module on main control module, the valve driving module connects valve, and when gas meter, flow meter detects the unusual or supply voltage of gas flow when under-voltage, main control module just by valve driving module controls valve closing breather line, stops air feed; After gas flow and supply voltage recovery normally, main control module is opened breather line with regard to by-pass valve control, recovers air feed.
