Abstract
The utility model discloses a kind of wireless gas alarm, including power module, wireless alarm signal receiving module and relay module, wherein power module connects wireless alarm signal receiving module and relay module respectively, wireless alarm signal receiving module is also connected with relay module, wireless alarm signal receiving module is used to receive alarm signal, and relay module is also connected with gas piping magnetic valve and vent fan.Wireless gas alarm of the present utility model can close gas piping magnetic valve in time according to alarm signal, open vent fan, so as to break off the leakage of fuel gas, reduce the concentration of fuel gas in air.
Description
Technical field
A kind of controller is the utility model is related to, specifically a kind of wireless gas alarm.
Background technology
The extensive use of gas, while many facilitate is brought to people's live and work, there is also many
Potential safety hazard.These potential safety hazards are mainly shown as, combustion gas has a possibility of leakage during conveying and use, and present institute
By the use of gas (mainly composition be methane) as a kind of fuel gas, when reaching finite concentration in the environment, run into bright
Fire can produce blast or fire, the safety of life and property to people bring high risks, cause extreme loss.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of wireless gas alarm, can be can
The leakage of gas is prevented when firing gas leakage in time, and reduces the concentration of fuel gas in control as early as possible, avoids generation bigger
Disaster and loss.
What the purpose of this utility model was realized in：A kind of wireless gas alarm, including it is power module, wireless
Alarm signal receiving module and relay module, power module connect wireless alarm signal receiving module and relay mould respectively
Block, wireless alarm signal receiving module are also connected with relay module, and wireless alarm signal receiving module is used to receive alarm signal,
Relay module is also connected with gas piping magnetic valve and vent fan.
Further, wireless alarm signal receiving module includes signal amplification circuit, filter circuit and decoding circuit, and signal is put
Big circuit, filter circuit and decoding circuit are sequentially connected.
Further, power switch is provided between power module and power supply.
Further, relay module includes normal-closed end and normally opened end, and normal-closed end connection gas piping magnetic valve, normally opened end connects
Connect air port exhaust fan.
Further, relay module also includes optical coupling isolation circuit and control relay circuit, and control relay circuit is used
It is opened or closed in control normal-closed end and/or normally opened end.
The utility model has the advantage of：Wireless gas alarm of the present utility model, can let out in fuel gas
The leakage of gas is prevented during dew in time, and reduces the concentration of fuel gas in control as early as possible, avoids that bigger disaster and damage occurs
Lose.
Brief description of the drawings
Fig. 1 is wireless gas alarm system construction drawing of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
The utility model is a kind of wireless gas alarm, including power module, wireless alarm signal receiving module
And relay module, power module connect wireless alarm signal receiving module and relay module respectively, wireless alarm signal connects
Receive module and be also connected with relay module, wireless alarm signal receiving module is used to receive alarm signal, and relay module is also connected with
Gas piping magnetic valve and vent fan；Wherein wireless alarm signal receiving module includes signal amplification circuit, filtered electrical
Road and decoding circuit, signal amplification circuit, filter circuit and decoding circuit are sequentially connected；It is provided between power module and power supply
Power switch；Relay module includes normal-closed end and normally opened end, normal-closed end connection gas piping magnetic valve, normally opened end connection ventilation
Mouth exhaust fan；Relay module also includes optical coupling isolation circuit and control relay circuit, and control relay circuit is used to control
Normal-closed end and/or normally opened end are opened or closed.
Wireless gas alarm of the present utility model so works：Turn on the power switch, the supply of 220V power supplys
Power module and relay module work, power module work export+5V to wireless receiving module and relay module, relay
Module normal-closed end exports 220V power supplys and gives gas piping magnetic valve, and electromagnetic valve work, it is normal that vent fans contact relay module
Beginning, vent fan do not work.
After wireless alarm signal receiving module receives alarm signal, control relay module works, and Control is normal
Closed end disconnects, and gas piping magnetic valve is stopped, to prevent fuel gas from continuing to reveal；Normally opened end is controlled to close, ventilating opening
Exhaust fan works, and reduces the concentration of fuel gas in control, reduces dangerous.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate the application example, and simultaneously
The non-restriction to embodiment.For those of ordinary skill in the field, can also do on the basis of the above description
Go out other various forms of changes or variation.There is no necessity and possibility to exhaust all the enbodiments.And thus drawn
Among the obvious changes or variations that Shen goes out is still in the protection domain of the application type.
