Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, the kitchen fire-away alarm and video linkage device comprises a kitchen room 1, a stove 2, a fire-away alarm host 3 and an online early warning supervision platform 8;
the fire-away alarm host 3 is electrically connected with a thermometer 4, a human body induction detector 5, a monitoring camera 6 and an audible and visual alarm 7, and the stove 2 is arranged in the induction range of the human body induction detector 5.
The fire-away alarm host 3 is connected with an online early warning and supervision platform 8 through a network, and the online early warning and supervision platform 8 comprises a system server, a PC client and a mobile phone client. The fire-away alarm host 3 is connected with a range hood control cabinet 9.
The human body induction detector 5 comprises a microwave induction switch a13 and a microwave induction switch b14, in order to prevent misoperation, two microwave induction switches are arranged, the microwave induction switch a13 and the microwave induction switch b14 are connected in parallel and are respectively connected between a zero line and a live line, and a main switch 10 and a fume exhaust fan contactor 11 are connected on the live line. Oil extraction cigarette fan contactor 11 belongs to lampblack absorber switch board 9, and oil extraction cigarette fan contactor 11 is used for linking with the lampblack absorber, and the lampblack absorber starts the back, and the fire just begins work from people's device.
