Abstract
The invention relates to a gas alarm with voltage output. The gas alarm with the voltage output comprises a microcontroller and is characterized in that the microcontroller is connected with a power supply output module to supply power to external devices. The gas alarm can directly supply power to a gas meter through a power supply output interface arranged on the gas alarm, so that batteries do not need to be replaced. Furthermore, due to the fact that the gas alarm can supply power to the external devices such as the gas meter, power supplied by a detector enables the gas meter to work normally even though the gas meter does not have the batteries.
Description
Technical field
The present invention relates to a kind of fuel gas alarm with Voltage-output.
Background technology
Combustible gas probe is a kind of gas leakage detection alarm instrument.When flammable in the environment or toxic gas are revealed, be when combustable gas concentration reaches the critical point of detector setting in the air, combustible gas probe will send sound, light is reported to the police, output alarm signal is to gas meter, flow meter simultaneously, gas meter, flow meter disable motor valve, with the generation of Accident prevention, and present intelligent gas meter is all powered with dry cell.
Summary of the invention
The purpose of this invention is to provide a kind of fuel gas alarm with Voltage-output, thereby can avoid changing battery in the gas meter, flow meter for gas meter, flow meter power supply.
A kind of fuel gas alarm with Voltage-output comprises microcontroller, and its special feature is: described microcontroller is connected with a power supply output module, thereby can power for external unit.
Wherein microcontroller also is connected with the gas alarm module, thereby the gas leakage alarm is being arranged.
Wherein microcontroller also is connected with the forced-ventilated relay module, ventilates thereby open the forced-ventilated fan when gas leakage; And microcontroller also is connected with the gas emergency cut-off valve module, thereby cuts off source of the gas when gas leakage.
Wherein microcontroller adopts single-chip microcomputer.
Fuel gas alarm of the present invention can directly be powered to gas meter, flow meter by its power output interface that carries, thereby need not change battery, in addition because this fuel gas alarm can provide power supply to power to external units such as gas meter, flow meters, even therefore gas meter, flow meter is not installed battery, the power supply that detector provides also can make the gas meter, flow meter normal operation.

Wherein microcontroller also is connected with the gas alarm module, and when gas leakage was arranged, the gas alarm module was sent sound, light is reported to the police, and this microcontroller also is connected with the forced-ventilated relay module respectively, opens the forced-ventilated fan when being used for gas leakage and ventilates; Also be connected with the gas emergency cut-off valve module simultaneously, cut off source of the gas when being used for gas leakage, ensure and use gas safety.
Of the present invention specifically composed as follows:
1, microcontroller:
Adopt the C8051F330 single-chip microcomputer of 51 series as the microcontroller of alarm.
2, power supply output module:
Mainly consisted of by three terminal integrated voltage stabilizer 78M06, commutation diode and filter capacitor, thereby for gas meter, flow meter or other external unit provide the power supply of 6V, for the gas meter, flow meter normal operation.
3, gas alarm module
Mainly consisted of by hummer, light emitting diode and driving circuit, in case the simultaneously LED flash then hummer is uttered long and high-pitched sounds of reporting to the police.
4, forced-ventilated relay module:
Formed by SRD-12VDC-SL-C solid-state relay and driving circuit.Ventilate by being connected with exhaust fan.
5, gas emergency cut-off valve module:
Offered the positive negative pulse stuffing of emergency cut-off valve breakdown by triode S0805 and the driving circuit that consists of of protection diode.
