Abstract
The utility model discloses a measurement revising membrane-type gas meter which comprises a display screen, a wireless receiving and sending module, a memorizer, a power supply module and a collecting module, wherein the display screen, the wireless receiving and sending module, the memorizer, the power supply module and the collecting module are respectively connected with a microprocessor. The measurement revising membrane-type gas meter is characterized by further comprising a pressure sensor, a temperature sensor and an alarm module, wherein the pressure sensor and the temperature sensor are arranged inside a cavity body of the gas meter, the alarm module is arranged on a meter shell of the gas meter, the pressure sensor and the temperature sensor are respectively connected with the microprocessor, and the collecting module is a photoelectric counter connected with a character wheel located at the position of an outlet of the gas meter. Collected pressure and temperature are transmitted to the microprocessor by the pressure sensor and the temperature sensor, wherein the pressure sensor and the temperature sensor are located inside the cavity body of the gas meter; an error rate brought by the measured pressure and temperature to gas measurement is figured out through comparing of the measured pressure and temperature with standard pressure and temperature by the microprocessor, wherein the standard pressure and temperature are set inside the microprocessor; and after data signals transmitted back by the photoelectric counter are revised, the revised data signals are sent to an upper server through the wireless receiving and sending module, and accordingly accuracy of data collection is effectively guaranteed.
Description
Technical field
The utility model relates to the device that gas metering is used, and is specifically related to a kind of diaphragm gas meter that the data-signal of gathering is carried out sending to by network behind the amendment type host computer.
Background technology
At present, the metering performance of diaphragm gas meter is in specified conditions (20 ℃) calibrating down, and cubing, yet uses under different temperatures, because the combustion gas volume change is very big, its metering is just inaccurate.No matter gas meter, flow meter is installed in outdoor or indoor, temperature and pressure reduction all can along with from different places, season different changing; Especially northern, temperature Change is particularly outstanding, and winter temperature reaches more than 5 months below 0 ℃, and summer temperature is more than 30 ℃, less than 3 months.Realize the metering gas volume with diaphragm gas meter like this, will have very big error, generally in ± 5% scope, this makes that to the user still be all unusual unfairnesses of gas company.

Embodiment
As shown in Figure 1, this metering amendment type diaphragm gas meter comprises display screen, radio receiving transmitting module, storer, power module and the acquisition module that is connected with microprocessor respectively, it is characterized in that: also comprise the pressure transducer and the temperature sensor that are arranged in the gas meter, flow meter metering cavity, and be arranged on the alarm module on the gas meter, flow meter watchcase; Described pressure transducer, temperature sensor and alarm module are connected with microprocessor respectively; Described acquisition module is the photoelectric counter that is connected with the character wheel in gas meter, flow meter exit.
Metering amendment type diaphragm gas meter also comprises a solenoid valve that is arranged on gas meter, flow meter air intake opening place, and described solenoid valve is connected with microprocessor; Described microprocessor is single-chip microcomputer; Described alarm module is audible-visual annunciator.
During this metering amendment type diaphragm gas meter work:
Pressure transducer and temperature sensor in the gas meter, flow meter metering cavity pass to microprocessor with the pressure and temperature of gathering, microprocessor compares by the normal pressure and temperature that arranges in it, calculate the pressure of measurement, the error rate that temperature is brought to the combustion gas measurement, the data-signal that transmission is returned to photoelectric counter is revised the back and is sent to higher level's server by radio receiving transmitting module, thereby has guaranteed the accuracy of data acquisition effectively; If pressure transducer and temperature sensor have data-signal output, and the output of photoelectric counter no datat signal, microprocessor judges that gas meter, flow meter breaks down, and microprocessor controls solenoid valves is closed, and the blocking-up combustion gas enters, and the guide sound light crossing-signal starts.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement to the utility model, these improvement also fall in the protection domain of the utility model claim.
