Embodiment Construction
[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0039] The invention provides an imaging device, referring to figure 1 and figure 2 , in this embodiment, the camera 1 includes a camera 10, a control chip 11, an infrared filter 12 and a communication module 13, and the infrared filter 12 is movably arranged on the light incident side A of the camera 10,
[0040] When the control chip 11 receives a visible light shooting instruction (the visible light shooting instruction is a user input or a default command for starting up the camera device), the control chip 11 controls the infrared filter 12 to deviate from the light incident side of the camera 10 The light entrance of A (not shown in the figure), so that the camera 10 collects visible light images and sends the collected visible light images to the control chip 11, and the control chip 11 is used to generate im...

The invention discloses a camera apparatus. The camera apparatus comprises a camera, a control chip, an infrared optical filter and a communication module. The infrared optical filter is movably arranged at the incident side of the camera, the control chip, when receiving a visible light shooting instruction, controls the infrared optical filter to deviate from an incident port at the incident side of the camera, the camera acquires a visible light image, and the control chip is used for determining whether a monitoring area is at a preset fire risk state; when the monitoring area is at the preset fire risk state, the infrared optical filter shields the incident port at the incident side of the camera; and the control chip, according to a received infrared light image, determines whether the monitoring area is at a preset fire state, and when the monitoring area is at the preset fire state, sends second fire alarm information to a preset monitoring server. The invention also discloses a fire detection alarm system and method. According to the invention, visible light image acquisition and infrared light image acquisition are integrated together, and the cost of the camera apparatus and the cost for arranging the fire detection alarm system based on the camera apparatus are reduced.
Description
technical field [0001] The invention relates to the technical field of fire detection and alarm, in particular to an imaging device, a fire detection and alarm system and a method. Background technique [0002] At present, there are generally three types of fire detection systems on the market. The first is to use traditional fire sensors (such as temperature sensors, smoke sensors, and gas sensors) for fire detection. The gas sensor is a contact sensor. Its principle is to detect the physical parameters (such as concentration, temperature) and the variation of these physical parameters generated during the fire process. It is mainly used for indoor small-scale fire detection. The fire detection method of the infrared sensor has the disadvantages of limited space applicability, poor information reliability, and susceptibility to external interference; the second is to use the infrared sensor for fire detection, but the expensive price of the infrared sensor limits its scope ...
