Detailed description of the invention
Provide the detailed description of the invention of a kind of gas heater safety detection device of the utility model below in conjunction with accompanying drawing, but enforcement of the present utility model is not limited to following embodiment.
See Fig. 1.A kind of gas heater safety detection device, containing controller 2, carbon monoxide gas sensor 3, carbon dioxide gas dependent sensor 4, buzzer 5 and window motor 7.Described controller 2 is containing control chip, connecting circuit and city's arrangements of electric connection or battery.Described control chip can adopt TMS320LF2812 chip.Most high threshold and the gas heater 1 cumulative operation time limit value of carbon monoxide and carbon dioxide are set in described control chip: the most high threshold of carbon monoxide is set to 200ppm; The most high threshold of carbon dioxide is set to 10000PPM; The each cumulative operation time limit value of gas heater 1 is 3 hours.Described controller 2 is connected with the switch of gas heater 1, to monitor the water heater working time.
In shower wall surrounding, carbon monoxide gas sensor 3 and carbon dioxide gas dependent sensor 4 and buzzer 5 are set.If needed, several carbon monoxide gas sensors 3 and carbon dioxide gas dependent sensor 4 can be set.Described carbon monoxide gas sensor 3, carbon dioxide gas dependent sensor 4 and buzzer 5 are electrically connected with described controller 2, described carbon monoxide gas sensor 3, carbon dioxide gas dependent sensor 4 and buzzer 5 is controlled by described controller 2.
By relative with shower door 8 for described bathroom window 6 and establish, make it more to be conducive to ventilating.On bathroom window 6 side, a window motor 7 is set.Described bathroom window 6 should adopt intelligent window, controls window motor 7 open or close by controller 2.The SCD300-M type motor that described window motor 7 can adopt Shanghai Lu Li intelligent door and window Co., Ltd to produce.Described window motor 7 is connected with the headstock gear of bathroom window 6, more described window motor 7 is electrically connected with described controller 2, make opening or close and controlling by described controller 2 of described bathroom window 6.
Once CO and CO that described carbon monoxide gas sensor 3, carbon dioxide gas dependent sensor 4 detect
2when gas concentration is greater than the most high threshold of setting in control chip, or during the setting limit value of each cumulative operation time of gas heater 1 more than 3 hours, described controller 2 starts buzzer 6 immediately and carries out reporting to the police and by window motor 7, bathroom window 6 is opened ventilation simultaneously.
If needed, can on described controller 2 attachment means, described controller 2 arranges PSTN system and gsm system: PSTN Internet Transmission selected by controller 2 under normal circumstances, when PSTN network failure, controller 2 automatically converts GSM network transmission to and the fault message of PSTN can be reported by GSM network.The data format transmitted by GSM is that SMS information mode delivers to mobile phone, or CID or the SIA format information of audio frequency delivers to receive centre equipment; So when described controller 2 can be reported to the police there is gas leakage or anoxia phenomenon situation: by mobile data network send alarming short message to programmed emergency or and Times 110 to obtain rescue.
See Fig. 2.The operation principle of a kind of gas heater safety detection device of the utility model is:
(1) in the control chip of described controller 2, CO and CO is set
2most high threshold and the limit value of each cumulative operation time of gas heater 1.
(2) CO and CO is monitored with carbon monoxide gas sensor 3, carbon dioxide gas dependent sensor 4
2gas concentration; When having multiple carbon monoxide gas sensor 3 and multiple carbon dioxide gas dependent sensor 4, to CO and CO
2the monitoring of gas concentration is using the mean value of sensor as detected value.
As CO or CO in bathroom
2when gas concentration does not reach setting threshold value, carbon monoxide gas sensor 3 and carbon dioxide gas dependent sensor 4 export high level signal.As long as any one of carbon monoxide gas sensor 3 or carbon dioxide gas dependent sensor 4 reaches setting threshold value, carbon monoxide gas sensor 3 or carbon dioxide gas dependent sensor 4 will output low level signals.
(3) when each cumulative operation time of the gas heater 1 shown on described control chip exceedes limit value, described control chip output low level signal, illustrates the danger that may exist in use.
Otherwise output high level signal.
(4) when carbon monoxide gas sensor 3 or carbon dioxide gas dependent sensor 4 and the monitoring that works all export high level, show that gas heater 1 is in a safe condition, controller 2 can not drive other component working.
(5) when any one transducers output low-level, show that safety problem has appearred in gas heater 1.After described controller 2 receives low level signal, buzzer 5 warning reminding related personnel can be started immediately; Meanwhile, described controller 2 can control window motor 7 and bathroom window 6 is opened ventilation, to ensure personal security.
(6) as CO or CO
2gas concentration drops to below threshold value, and meanwhile, when each cumulative operation time of gas heater 1 does not transfinite yet, controller 2 receives high level signal, stops starting buzzer 5, controls window motor 7 and is closed by bathroom window 6.Control system resets.
