According to the coal gas leakage processing system, the coal gas pipeline is turned off automatically when coal gas is leaked, and the alarm can be given in various modes in time when the coal gas pipeline is not turned off successfully.
Description
Technical field
The present invention relates to Smart Home technical field, particularly relate to a kind of gas leak disposal system.
Background technology
At present, the combustion gas in city, mainly based on piped gas, although bring conveniently for daily life, due to the combustibility of coal gas and containing toxic gas carbon monoxide, also exists certain potential safety hazard.People forget the valve of closing gas piping outlet sometimes after using coal gas, and this may cause fire or gas poisoning, even coal gas blast accident.Therefore, how realizing automatically dying of coal gas when people forget closing valve, is a problem needing solution badly.
In order to use coal gas more relievedly, in intelligent domestic system, being integrated with coal gas detecting and gas automatic shutoff function, namely detecting gas concentration by sensor, once gas concentration exceeds standard, just control coal gas inductive switch and automatically close coal gas.But gas sensor and coal gas inductive switch exist situation about losing efficacy, now, still there will be the situation that coal gas continues to leak.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of gas leak disposal system, can automatically shut down gas piping when gas leak, and when gas piping turns off unsuccessful, carries out various ways warning in time.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of gas leak disposal system, described gas leak disposal system comprises and is arranged in gas piping and is in the solenoid valve of off-state, be arranged on gas piping exit and the first gas sensor be electrically connected with described solenoid valve, away from the second gas sensor of gas piping outlet, the audible-visual annunciator be electrically connected with described second gas sensor, electrically driven curtain and gsm communication module, described first gas sensor be used for detect gas concentration detected value control when exceeding warning value described solenoid valve turn off gas piping, described second gas sensor is used for detecting that gas concentration detected value controls described audible-visual annunciator and reports to the police when exceeding described warning value, control described electrically driven curtain to open and carry out ventilating and control described gsm communication module and send alarming short message.
Preferably, described first gas sensor is electrically connected with described second gas sensor, and described second gas sensor detects at described first gas sensor and to start after gas concentration detected value exceeds warning value to detect.
Preferably, described first gas sensor distance gas piping exports within 0.5 meter.
Preferably, described second gas sensor distance gas piping exports 10 meters to 15 meters.
The invention has the beneficial effects as follows: the situation being different from prior art, the present invention detects gas leak situation by two gas sensors, a gas sensor is close to gas piping outlet, gas piping is turned off for Controlling solenoid valve, a gas sensor is away from gas piping outlet, report to the police for controlling audible-visual annunciator when gas piping turns off unsuccessful, control electrically driven curtain is opened and is ventilated, and control gsm communication module transmission alarming short message, thus gas piping can be automatically shut down when gas leak, and when gas piping turns off unsuccessful, carry out various ways warning in time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the gas leak disposal system of the embodiment of the present invention.
Embodiment
Arbitrary feature disclosed in this instructions, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Referring to Fig. 1, is the schematic diagram of the gas leak disposal system of the embodiment of the present invention.The gas leak disposal system of the embodiment of the present invention comprises and is arranged in gas piping 1 and is in the solenoid valve 2 of off-state, be arranged on gas piping 1 exit and the first gas sensor 3 be electrically connected with solenoid valve 2, away from the second gas sensor 4 that gas piping 1 exports, the audible-visual annunciator 5 be electrically connected with the second gas sensor 4, electrically driven curtain 6 and gsm communication module 7, first gas sensor 3 turns off gas piping 1 for the Controlling solenoid valve 2 when detecting that gas concentration detected value exceeds warning value, second gas sensor 4 is reported to the police for controlling audible-visual annunciator 5 when detecting that gas concentration detected value exceeds warning value, control electrically driven curtain 6 to open and carry out ventilating and control gsm communication module 7 and send alarming short message.
Solenoid valve 2 is embedded in gas piping 1, is usually in off-state, ensures that the air-flow of gas piping 1 is unobstructed.When the first gas sensor 3 detects that gas concentration detected value exceeds warning value, first gas sensor 3 sends cut-off signals to solenoid valve 2, solenoid valve 2 connects circuit after receiving cut-off signals, solenoid valve 2 adhesive, thus turn off gas piping 1, make coal gas stop exporting, ensure coal gas safety in utilization.。
When solenoid valve 2 because fault cannot adhesive time, coal gas can continue to leak, and spread in house, when coal gas diffusion certain limit, the second gas sensor 4 detects that gas concentration detected value exceeds warning value, control audible-visual annunciator 5 and carry out sound and light alarm, control electrically driven curtain 6 is opened and is ventilated, and continues to increase to prevent indoor gas concentration, and control gsm communication module 7 sends alarming short message, to inform gas leak in homeowners family, and cannot automatically get rid of gas leak fault.
Alternatively, the first gas sensor 3 is electrically connected with the second gas sensor 4, and the second gas sensor 4 detects at the first gas sensor 3 and to start after gas concentration detected value exceeds warning value to detect.Second gas sensor 4 can be in low power consumpting state at ordinary times, first gas sensor 3 detects that send activation signal after gas concentration detected value exceeds warning value starts to detect after the second gas sensor 4, second gas sensor 4 receives activation signal.In the present embodiment, the first gas sensor 3 exports within 0.5 meter apart from gas piping 1, and the second gas sensor 4 exports 10 meters to 20 meters apart from gas piping 1.
The gas leak disposal system of the embodiment of the present invention can not only automatically shut down gas piping when gas leak by solenoid valve, and when gas piping turns off unsuccessful, electrically driven curtain can be opened in time again to ventilate, and carry out sound and light alarm and SMS alarm, guarantee warning generation effect, improve the robotization performance that coal gas detects.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
