Accompanying drawing explanation
Fig. 1 is the combustion gas state acquisition process block diagram of one embodiment of the invention.
Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the combustion gas state acquisition process block diagram of one embodiment of the invention, see Fig. 1, described in the invention is a kind of intelligent gas meter had into water measuring ability, this gas meter, flow meter outer setting has terminal computer, comprise base table, base table inside is provided with controller unit, A/D conversion chip, pressure transducer, radio receiving transmitting module, operation valve, sound and light alarm module.
Pressure transducer is arranged on the panel itself of base table, and its range is 0-1.5MPa, connects the input end of A/D conversion chip, flows through the air pressure of combustion gas generation, the input end of the output terminal connection control device unit of A/D conversion chip for detecting base table inside.The air pressure simulating signal that pressure transducer detects converts digital signal to through A/D conversion chip and is transferred to controller unit.Sound and light alarm module is connected with controller unit, for receiving the alerting signal from controller unit.
Controller unit is by radio receiving transmitting module accessing Internet, and terminal computer is by internet notification far-end civil gas management system.Controller unit is connected with operation valve by valve driving circuit, and valve driving circuit accesses terminal computer.Further, operation valve is the output terminal of four line motor valves, its input end connection valve gate drive circuit, and the input signal according to receiving driving circuit opens or closes; Wherein, two lines connect the both positive and negative polarity of power supply, and other two lines receive operation valve switches and to put in place detection signal.
Pressure transducer gathers the pressure information of the inner combustion gas of base table through producing, and is converted into corresponding detection signals, is input to described terminal computer by controller unit.Terminal computer is at least preset with the abnormality threshold range of the pressure corresponding with base table body, service time in cycle, for with come from the pressure information comprised in the pressure detecting signal of pressure transducer and contrast, judge by valve driving circuit according to comparing result and then control the unlatching of operation valve or close gas meter, flow meter gas admittance valve.Wherein, the abnormality of pressure is within the predetermined period time, flow through combustion gas air pressure in base table body not in preset range value, and gaseous-pressure is greater than 5KPa.The abnormality of service time in cycle be within the predetermined period time, flow through base table combustion gas air pressure in normal range, but the duration exceeded preset value.Service time in cycle can be arranged with actual conditions.
