CN104732704A - Intelligent smoke alarm and working method thereof - Google Patents

Abstract

An intelligent smoke alarm comprises a controller and a smoke sensor, a camera and an audible and visual alarm which are connected with the controller. The intelligent smoke alarm does not immediately give an alarm when detecting smoke, whether a firing phenomenon occurs in a room is judged firstly through video collection, false alarm caused by various factors is avoided, and the unnecessary problem that noise disturbs residents is avoided.

Description

Intelligent smog alarm and method of work thereof

Technical field

The present invention relates to a kind of warning device, specifically, is a kind of intelligent smog alarm and method of work thereof.

Background technology

Fire is more multiple a kind of accident, and before fire occurs, all can occur smog, in order to improve the reaction velocity of fire alarm, many premises are all provided with smoke alarm.But current alarm, detects that smog just sends warning, when the people in the room smog that the smog, the culinary art that produce produce of smoking also can excite alarm, send chimes of doom, cause false alarm, harassing and wrecking resident family.

Summary of the invention

The present invention is directed to above-mentioned the deficiencies in the prior art, devise a kind of intelligent smog alarm and method of work thereof.

Intelligent smog alarm of the present invention, comprise controller and be connected with controller smoke transducer, camera, audible-visual annunciator.

A method of work for intelligent smog alarm, step is as follows:

1) air of smoke transducer to indoor detects;

2) when smoke transducer detects smog, smoke transducer sends signal to controller;

3) controller Received signal strength, controls camera collection off-the-air picture;

4) controller receives image, and analyzes image, judges whether have combustion phenomena in room;

5) if having burning in room, controller controls audible-visual annunciator and sends sound and light alarm.

The invention has the beneficial effects as follows: intelligent smog alarm is not reported to the police when smog being detected at once, but first judge whether there is phenomenon on fire in room by video acquisition, avoid the false alarm that various factors causes, avoid unnecessary noise and to disturb residents problem.

Accompanying drawing explanation

Accompanying drawing 1 is the structured flowchart of intelligent smog alarm.

Embodiment

Intelligent smog alarm of the present invention, as shown in Figure 1, comprise controller and be connected with controller smoke transducer, camera, audible-visual annunciator.

During use, the air of smoke transducer to indoor detects.

When smoke transducer detects smog, smoke transducer sends signal to controller.

Controller Received signal strength, controls camera collection off-the-air picture.

Controller receives image, and analyzes image, judges whether have combustion phenomena in room.

If have burning in room, controller controls audible-visual annunciator and sends sound and light alarm.

Claims (2)

1. an intelligent smog alarm, is characterized in that, comprise controller and be connected with controller smoke transducer, camera, audible-visual annunciator.
