Fuel gas alarm with wireless self-networking function
Technical field
The present invention relates to a kind of fuel gas alarm with wireless self-networking function.
Background technology
Combustible gas probe (fuel gas alarm) is a kind of gas leakage detection alarm instrument.When flammable in the environment or toxic gas are revealed, be that combustible gas probe will send sound, light is reported to the police when combustable gas concentration reached the critical point of detector setting in the air, output alarm signal is to gas meter, flow meter simultaneously, gas meter, flow meter disable motor valve is with the generation of Accident prevention.Present combustible gas probe all only has sound and light of alarm.
Summary of the invention
The purpose of this invention is to provide a kind of fuel gas alarm with wireless self-networking function, thereby can be connected network consisting in the residential quarter by wireless mode with wireless receiver.
A kind of fuel gas alarm with wireless self-networking function comprises microcontroller, and its special feature is: thus described microcontroller is connected with a wireless communication module and can communicates by letter by wireless mode with wireless receiver.
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 gas emergency cut-off valve module, thereby cuts off source of the gas when gas leakage.
Wherein microcontroller adopts single-chip microcomputer.
Wherein wireless receiver is installed in the duty room.
The present invention adopts the fuel gas alarm with wireless self-networking function, by adding wireless module at fuel gas alarm, has realized networking and unmanned in the residential quarter.Fuel gas alarm kind of the present invention can be carried out wireless telecommunications with wireless receiver, thereby and can the automatically more convenient use of network consisting in the residential quarter.In case community user has gas leakage alarm, the residential quarter operator on duty namely knows it is which family, which unit, which building, and processes accordingly fast.
Description of drawings
Accompanying drawing 1 is logic theory block diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention is a kind of fuel gas alarm with wireless self-networking function, comprises microcontroller, thereby described microcontroller is connected with a wireless communication module and can communicates by letter by wireless mode with wireless receiver.
Wherein microcontroller also is connected with the gas alarm module, thereby reports to the police by sound, light when gas leakage is arranged, and microcontroller also is connected with the gas emergency cut-off valve module, thereby cuts off source of the gas when gas leakage, ensures and uses gas safety.
Wherein microcontroller adopts single-chip microcomputer, and wireless receiver is installed in the duty room.
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, wireless communication module:
Adopt integrated LSDRF4710N01 wireless transceiver for Internet of Things to consist of wireless communication module with relevant driving circuit, thereby realize wireless telecommunications.
3, wireless receiver:
The communication module of wireless communication module coupling is connected with single-chip microcomputer again in employing and the alarm, and the alarm signal of single-chip microcomputer by receiving provides alarm by display screen or speech IC.
4, sound and light 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.
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.
