Solar powered intelligent gas meter

Technical field

The utility model relates to a kind of intelligent gas meter, particularly a kind of solar powered intelligent gas meter.

Background technology

In the existing intelligent gas meter, as IC-card gas meter, flow meter, wireless remote transmission gas meter, flow meter etc., particularly the power supply of people's subscriber's meter adopts powered battery mostly.These intelligent gas meters have generally all adopted the circuit design of little power consumption, and battery can use the long period.But this still can produce a large amount of used old and useless batterys, pollutes to environment.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of solar powered mode of utilizing is provided, as the power supply or the accessory power supply of intelligent gas meter, reaches the purpose of energy savings, cleaning, environmental protection.

The technical scheme that the utility model is taked has reached above-mentioned purpose of design, the utility model is made of solar panel, voltage stabilizing chip, energy-storage travelling wave tube and intelligent gas meter control circuit, the output of solar panel is connected with the voltage stabilizing chip, voltage stabilizing chip voltage output terminal connects energy-storage travelling wave tube, and the energy-storage travelling wave tube output terminal is connected with intelligent gas meter control circuit power supply.

Solar panel of the present utility model is selected a kind of dyssophotic non-crystal silicon solar cell plate, and its feature is also can set up the necessary operating voltage of load under indoor more weak scattered light condition.Behind the voltage stabilizing chip of voltage with the solar panel generation, energy-storage travelling wave tube (super capacitor or accumulator) is charged, be supplied to the circuit board of intelligent gas meter to use simultaneously through a little power consumption.

When visible light reached illumination, the voltage that solar panel produces after the voltage stabilizing of little power consumption voltage stabilizing chip, charged to super capacitor, offers the work of intelligent gas meter circuit board with battery simultaneously, can reduce battery consumption; When visible light does not reach illumination, keep voltage output by the super capacitor discharge; When the super capacitor electric weight is not enough, supply with the work of intelligent gas meter circuit board by battery.

The beneficial effects of the utility model are: the area stronger at sunshine can directly power to intelligent gas meter, do not re-use battery, under the situation of sunlight deficiency, can be used as auxiliary power supply, energy savings, reduce battery consumption, reduce the operating cost of intelligent gas meter, and reduce the old and useless battery pollution on the environment.
