Abstract
The utility model relates to an IC intelligent gas meter for preventing straight-through and ultra-flow, which comprises a basic meter 1 and a CPU connected together. The utility model is characterized in that: the basic meter 1 is internally provided with an electromechanical valve 4, the basic meter 1 is connected with a gas source input port 2, a gas source output port 3 and a CPU controller 5, and also connected with a counting dry-reed tube 6. After the electromechanical valve 4 is opened, the CPU controller 5 sends a program command for closing the valve to an electromechanical valve control circuit 8 in order to close the electromechanical valve 4, so as to close the gas source input port 2 and block gas to flow into the basic meter 1, thereby preventing users from continuing to use the gas during no-metering. The utility model can prevent inaccurate metering of gas meter under the condition of ultra-flow gas consumption.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter, and concrete is a kind of IC-card intelligent gas meter that prevents straight-through and super flow.
Background technology
At present, the principle of work of domestic common IC-card intelligent gas meter is: the user gives administrative authority with gas expense, administrative authority will purchase in the tolerance input IC-card, information input intelligent gas meter during the user will block, intelligent gas meter is the automatic valve opening air feed, in user's gas process just commonly used, base table carries out the metering of gas consumption, and the signal of gathering when base table measured changes the numeral metering into to control circuit, micro computer is according to the digital stoichiometric number gas consumption of examining and making cuts automatically, the tolerance of purchasing is used up, and intelligent gas meter valve-closing is died, and the user need purchase gas again can open the valve air feed once more.
But, when several abnormal conditions below the product appearance, all can cause gas meter, flow meter not measure, for example the user will show reversal connection, artificial destruction with the base table character wheel block, base table is originally experienced transportation or shake is installed causes base table not turn round or character wheel block, take a sample electron device or circuit breaks down, base table movement fault does not turn round, like this in the gas process in the intelligent gas meter tolerance of control circuit part just can't be reduced to zero and close valve, gas meter, flow meter will be in pass-through state, the user need not natural gas companies and purchases gas, also can continue to use combustion gas.Another situation is, national standard all defines the maximum flow that can pass through to the gas meter, flow meter of various different sizes at present, and when reality surpassed the flow value of this qualification by flow, the metering of gas meter, flow meter will be inaccurate.
The utility model content
For solve that existing IC-card intelligent gas meter may occur with gas meter, flow meter in the gas process do not measure and super flow after the problem of the inaccurate problem of metering, the utility model provides a kind of and can effectively prevent to lead directly to and the IC-card intelligent gas meter of super flow.
The utility model is achieved in that
A kind of IC-card intelligent gas meter, comprise continuous base table 1 and cpu controller 5, be provided with electromechanical valve 4 in the base table 1, base table 1 links to each other with source of the gas input port 2, source of the gas delivery outlet 3, cpu controller 5, counts tongue tube (6) in addition and links to each other with cpu controller (5) with base table (1) simultaneously
Further scheme is: counting tongue tube 6 is common counting tongue tube or antimagnetic counting tongue tube.
Further scheme is: cpu controller 5 links to each other with counting tongue tube 6 by counting tongue tube sampling control circuit 7; Link to each other with electromechanical valve 4 by electromechanical valve control circuit 8; Cpu controller 5 links to each other with IC-card read/write circuit 9, liquid crystal display circuit 10.
The beneficial effects of the utility model are can stop gas-flow to cross base table to avoid gas meter, flow meter user under the state that does not have metering to continue to use combustion gas; Perhaps the long-term unmanned situation of user's family also can avoid the gas consuming device flexible pipe to cause hidden dangers such as leakage because of a variety of causes.The utility model can also stop gas-flow to cross base table to prevent that gas meter, flow meter from error in dipping occurring under super flow status, guarantee the gas meter, flow meter accurate measurement.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cpu controller electrical block diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in accompanying drawing 1,2, the utility model is taken a sample by 6 pairs of gas quantities that pass through of counting tongue tube, and sampling result is sent to cpu controller 5, utilize cpu controller 5 internal clocking functions, by the start time of establishing valve by cable on program compilation setting and the storage IC-card intelligent gas meter, pick up counting from power on cycle of first sampled signal by program setting in advance.After electromechanical valve is opened, if tongue tube does not have acquired signal then closes electromechanical valve for the electromechanical valve control circuit by the programmed instruction that CPU sends valve-off in the cycle of this setting, thereby close the source of the gas input port, stop gas-flow to cross base table and avoid gas meter, flow meter user under the state that does not have metering to continue to use combustion gas; Perhaps the long-term unmanned situation of user's family also can avoid the gas consuming device flexible pipe to cause hidden dangers such as leakage because of a variety of causes.
In addition, situation for super flow usefulness gas, be sampled to cpu controller 5 by the counting tongue tube, the normal space time when mean value that utilizes CPU computing function synchronometer to calculate continuous three acquired signal interval times allows maximum metered flow with this model specification combustion gas that is stored in 5 li of cpu controllers in advance compares, thereby judge automatically whether the gas meter, flow meter metering has surpassed peak flow values, when flow surpasses maximum flow, cpu controller 5 can send the programmed instruction of valve-off and close electromechanical valve for the control circuit of electromechanical valve, thereby close the source of the gas input port, stop gas-flow to cross base table and prevent that gas meter, flow meter from error in dipping occurring under super flow status, guarantee the gas meter, flow meter accurate measurement.
The utility model has also increased the mode of antimagnetic counting tongue tube, use antimagnetic counting tongue tube after, the utility model can use in strong magnetic field circumstance and can not cause the counting tongue tube to lose efficacy.
In actual use, cpu controller reads IC information by the IC-card read/write circuit, and can information be come out by liquid crystal display displays by liquid crystal display circuit.
