Abstract
The utility model relates to an intelligent film gas meter adopting a double-reed pipe to sample flow pulse signals. The intelligent film gas meter comprises a micro-controller and a character wheel counter, wherein a first reed pipe is arranged beside the character wheel counter, and connected with the micro-controller by a peripheral circuit. The intelligent film gas meter is characterized in that a second reed pipe is arranged at the other side of the character wheel counter and also connected with the micro-controller by the peripheral circuit. The reed pipes are respectively arranged above and below the character wheel counter, and can not be conducted simultaneously, when a character wheel rotates, the two reed pipes can alternatively generate the pulse signals to the micro-controller, and the micro-controller can judge whether the reed pipes has faults according to a phase relationship of the signals; as the a double-pulse phase judging method, the micro-controller can self-diagnose the faults of the reed pipes; and if the reed pipes has the faults, a valve is shut immediately, so that the undercounting or non-counting of flow can be prevented.
Description
Technical field
The utility model relates to a kind of intelligent diaphragm gas meter that adopts double dry-reed pipe sampling flow pulse signal.
Background technology
Gas meter, flow meter is a kind of metering device that uses combustion gas that is used to measure.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 got into kitchen range from gas pipeline through gas meter, flow meter, connecting tube; General diaphragm gas meter is through being arranged on the mechanical type meter 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 confirm what of gas consumption through the numeral that shows on the counter.And present intelligent gas meter is obtained pulse signal through a tongue tube from the magnetite on the counter and is carried out flow metering, and the electronics metering just can not be carried out after tongue tube breaks down, but gas meter, flow meter still can continue use.
The utility model content
The purpose of the utility model provides a kind of intelligent diaphragm gas meter that adopts double dry-reed pipe sampling flow pulse signal; After one of them tongue tube fault occurring; Microcontroller just can be diagnosed and valve-off immediately, prevents that intelligent gas meter is in can not count but can continue the state of usefulness gas.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of intelligent diaphragm gas meter that adopts double dry-reed pipe sampling flow pulse signal; Comprise microcontroller and character wheel counter; Wherein at other first tongue tube that is equipped with of this character wheel counter, this first tongue tube is connected with microcontroller through peripheral circuit, and its special feature is; At said character wheel counter opposite side second tongue tube is installed also, this second tongue tube also is connected with microcontroller through peripheral circuit.
Wherein first tongue tube and second tongue tube are installed in the upper and lower both sides of character wheel counter respectively.
The utility model is respectively installed a tongue tube at the upper and lower of character wheel counter, and two tongue tube conductings simultaneously are when character wheel rotates; Two tongue tubes alternately produce pulse signal and give microcontroller; Judge whether to exist the tongue tube fault by microcontroller according to the phase relation of signal, owing to adopted dipulse phase determination method, microcontroller can self diagnosis has the fault of tongue tube; If tongue tube fault valve-off immediately then prevents few meter or disregards flow.
Description of drawings
Accompanying drawing 1 is the logic theory block diagram of the utility model;
Accompanying drawing 2 is the control flow chart of the utility model.
Embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing; As shown in Figure 1, comprise microcontroller and character wheel counter, wherein at other first tongue tube that is equipped with of this character wheel counter; This first tongue tube is connected with microcontroller through peripheral circuit; At the character wheel counter opposite side second tongue tube is installed also, this second tongue tube also is connected with microcontroller through peripheral circuit, is specially first tongue tube and second tongue tube and is installed in the upper and lower both sides of character wheel counter respectively.
By microcontroller the pulse signal that two tongue tubes produce is carried out sample count during use, metered flow is presented at LCD MODULE and is kept at memory module, can also pass through valve control module valve-off according to failure condition.
Claims (2)
1. intelligent diaphragm gas meter that adopts double dry-reed pipe sampling flow pulse signal; Comprise microcontroller and character wheel counter; Wherein at other first tongue tube that is equipped with of this character wheel counter; This first tongue tube is connected with microcontroller through peripheral circuit, it is characterized in that: at said character wheel counter opposite side second tongue tube is installed also, this second tongue tube also is connected with microcontroller through peripheral circuit.
2. the intelligent diaphragm gas meter of employing double dry-reed pipe sampling flow pulse signal as claimed in claim 1 is characterized in that: wherein first tongue tube and second tongue tube are installed in the upper and lower both sides of character wheel counter respectively.
