Preferably, described gas warning system also comprises air valve and is electrically connected on the 3rd relay switch of described gas sensor, and described 3rd relay switch receives described gas sensor signal, controls described air valve and closes.
Preferably, described gas warning system also comprises the main frame being connected to described audible-visual annunciator, and described main frame is connected to user mobile phone by GPRS network.
Preferably, described gas sensor inside is provided with controller, and for detecting gas concentration, when described gas concentration value is more than or equal to preset value, described audible-visual annunciator starts; When described gas concentration is less than described preset value, described audible-visual annunciator cuts out.
Preferably, described air valve is solenoid valve.
Preferably, described air valve is also socketed with sealing shroud.
Preferably, described audible-visual annunciator is also connected with earthing device.
Preferably, described audible-visual annunciator is inflammable gas audible-visual annunciator.
According to technique scheme, gas warning system provided by the invention comprises power supply, audible-visual annunciator, gas sensor, vent fan, gas sensor respectively with the first relay switch is connected with the second relay switch, when indoor gas concentration reaches preset value, first relay switch receives the signal of gas sensor, transfer closure state to from off-state, audible-visual annunciator is reported to the police; Side by side, the second relay switch receives the signal of gas sensor, transfers closure state to from off-state, and vent fan starts, thus can reduce the concentration of indoor harmful gas.Prevent indoor harmful gas concentration from exceeding certain value and injure personal safety.
Other features and advantages of the present invention are described in detail in embodiment part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for instructions, is used from explanation the present invention, but is not construed as limiting the invention with embodiment one below.In the accompanying drawings:
Fig. 1 is the schematic diagram of the gas warning system according to the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the nouns of locality be included in term such as " upper and lower, left and right, inside and outside " only represents the orientation of this term under normal service condition, or being commonly called as of understanding for those skilled in the art, and should not be considered as the restriction to this term.
The invention provides a kind of gas warning system, as shown in Figure 1, described gas warning system comprises power supply, gas sensor, audible-visual annunciator, vent fan, is electrically connected on the first relay switch of described gas sensor, is electrically connected on the second relay switch of described gas sensor, wherein, described power supply provides operating voltage, described first relay switch receives described gas sensor signal, control described audible-visual annunciator to start, described second relay switch receives described gas sensor signal, controls described vent fan and starts.According to total design aim of the present invention, when mainly providing one to prevent indoor gas concentration from exceeding certain value, injure the gas warning system of personal safety, this kind of gas warning system comprises power supply, gas sensor, audible-visual annunciator, vent fan, the first relay switch being electrically connected on described gas sensor respectively and the second relay switch, in addition, first relay switch is for controlling audible-visual annunciator, and the second relay switch is for controlling vent fan.When indoor gas concentration reaches certain predetermined value, the first relay switch receives the signal of gas sensor, transfers closure state to by off-state, and audible-visual annunciator is reported to the police, and produces alerting signal, reminds people to take measures in time, ensures safety; Meanwhile, the second relay switch receives the signal of gas sensor, also transfers closure state to from off-state, and now, vent fan starts, thus reduces indoor gas concentration, ensures personal safety.In addition, when indoor gas concentration drops to below preset value by vent fan, gas sensor quits work, then whole gas warning system quits work.
In the present invention, in order to ensure personal safety further, new gas can not be produced again time vent fan is vented, reduce the concentration of indoor gas faster, described gas warning system also comprises air valve and is electrically connected on the 3rd relay switch of described gas sensor, described 3rd relay switch receives described gas sensor signal, controls described air valve and closes.When indoor gas concentration exceedes preset value, the 3rd relay switch receives the signal of gas sensor, transfers closure state to by off-state, and now air valve is closed, forbid again by gaseous volatilization to indoor.
In the present invention, described gas warning system also comprises the main frame being connected to described audible-visual annunciator, and described main frame is connected to user mobile phone by GPRS network.Under preferable case, described audible-visual annunciator is inflammable gas audible-visual annunciator.Inevitably, when indoor inflammable gas reaches preset value, be such as coal gas, when indoor gas concentration exceedes certain value, people not only can be allowed to suffocate, also can produce blast, if residential block, then can cause large-scale blast, the infringement caused is very large.So when user goes out time, or certain parts in this gas warning system are when going wrong, situation described above will be caused, so audible-visual annunciator can be connected a main frame, this main frame is connected to user mobile phone by GPRS network, so just can reminding user, allows it return to take measures in time, reduce concentration, prevent dangerous generation.
In the present invention, described gas sensor inside is provided with controller, and for detecting gas concentration, when described gas concentration value is more than or equal to preset value, described audible-visual annunciator starts; When described gas concentration is less than described preset value, described audible-visual annunciator cuts out.It should be noted that, preset value described here is fixed as the case may be, is not particularly limited, as long as the concentration of setting can not injure personal safety.
In the present invention, the 3rd relay switch controls air valve and cuts out, and for the ease of control and management, described air valve is solenoid valve, when the 3rd relay switch closes, and closed electromagnetic valve, thus prevent indoor gas concentration from increasing further.
In addition, selectively, described air valve is also socketed with sealing shroud.Can be removably connect between sealing shroud and air valve, junction arranges seal, more convenient like this manual-lock air valve.In order to security consideration, prevent audible-visual annunciator to make moist electric leakage, described audible-visual annunciator is also connected with earthing device.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible array mode.
In addition, also can carry out combination in any between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
