Abstract
The present invention relates to a method for detecting fire with light section image to sense smoke. Infrared radiation arrays (1) and infrared cameras (2) are provided in a monitored area. The images of the infrared light spots transmitted by the infrared radiation arrays (1) are converted into video signals by the infrared cameras (2), and transferred to a video switcher (3). The video switcher sends the video signals received from the infrared cameras to a computer (4) one by one. The computer processes the signals. If fire is sensed, the computer controls the alarm unit (5) to alarm by a linkage.
