Beneficial effect:
Intelligent unmanned gas safety monitor of the present utility model, its core concept is to change thinking ideas, create a kind of scheme that replaces " limting concentration " enforcement warning of combustion gas based on " time length ", survey and determine that people's behavior is dynamic in mode initiatively, on " ideal time ", take precautions against in advance, from " root ", thoroughly break off source of the gas, " people-oriented ", accomplishes reliably, precisely and rapidly realizes and use gas safety guarantee completely.
The utility model can automatically be monitored from people's current intelligence in good time and effectively regularly be closed Gas-combustion valve.This kind of is designed to human-computer interaction, Intelligent Dynamic monitoring, closes automatic nobody-is-safe's protective device of combustion gas in good time.The main setting monitoring objective of function object is behaved.When people is during in setting regions activity, intelligent main controller can because of people arbitrarily standby take orders from.Once people leaves, just self-timing is closed total air valve.Main purpose be thoroughly solve and prevent because of stove when long from people without keeping an eye on, cause a pot interior full water to overflow stop working gas leakage or anhydrous dry combustion method, the serious combustion gas waste causing and the initiation of fire incident; No matter when the utility model also can be realized round the clock, meet building or family's fault outage as prominent, the protection of also urgent self-closing gas being ceased fire.Realize thoroughly eliminate or prevent because of stove when long from people without keeping an eye on, cause anhydrous dry combustion method in saucepan, in effectively preventing combustion gas serious waste, key is the initiation of stopping fire incident.
The utlity model has without operation, self-detection, self-timing, countdown and show, automatically close down the multi-functional advantages such as nobody-is-safe's intelligence of (combustion gas total gate valve) is on duty.When after device power (switching on power), a very important person enters monitoring (as kitchen) district, and it is dynamically on duty that intelligent main controller enters delay monitoring automatically.Only need manually (at every turn must) to propose to open the use of just can opening fire of the electromagnetic valve " small red cap " of gas pipeline.Due to, the protection automatically in default 20 minutes temporarily of intelligent main controller.So people is if any 1～n time behavioral activity with leave in short-term within this time limit, intelligent main controller all will automatically terminate (countdown) time of advancing at any time, and combustion gas can not stop closing down.Set the time limit as exceeded and leave, just intelligent main controller self-timing (containing fault outage) is closed total air valve, realize self-closing gas truce protection.
Above, owing to effectively realizing " in advance " anti-control techniques initiatively, realize from people's automatic self-closing gas gate valve, can avoid or reduce our gas leakage problem of long-term puzzlement and disaster hidden-trouble problem completely;
The utility model is designed to man-machine unification, has manually the function of opening, automatically closing " dual fail-safe ", safe and reliable.
The all right further basic gas concentration monitoring alarm of the utility model, function has obtained further expanding and is perfect like this.The interlock control of this additional gas concentration monitoring alarm, strengthens especially to the safe and reliable another guarantee of coming personally.
The utility model is realized arbitrary with the fire moment simultaneously, meets building or family's fault outage as prominent, and all tight speed is closed stop valve protection automatically.
In addition, Doppler radar inductor is the sensor of finally choosing through test of many times, compare other sensor (as infrared sensor, voice operated sensor, photoelectric sensor etc.), this Doppler radar inductor sensitivity is good, antijamming capability is strong, is particularly suitable for being applied in the occasions such as kitchen.
