However, if figure 1 As shown, when there are reflective objects such as mirrors and glass in the fire place, the sensor often cannot distinguish between the original image and the mirror image, causing the automatic water cannon to locate the fire point to the mirror image to extinguish the fire. It becomes a big fire, which brings great damage to personal safety and great loss to personal property and social public property.
[0003] Moreover, every time the automatic water cannon searches for a fire point, it takes a certain amount of time to scan all the positions in the fire place, which is a waste of time and may delay the best time to extinguish the fire

Embodiment Construction
[0016] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0017] A fire extinguishing system that quickly and accurately detects the point of fire, such as Figure 2-4 As shown, including automatic water cannon 1, control system and sensor array.
[0018] The automatic water cannon 1 includes a mechanical device and a water cannon, and the mechanical device is used for opening and closing the water cannon, and driving the water cannon for positioning. Specifically, the mechanical device is connected with the water cannon in a conventional manner, so that the water cannon can be turned on or off through the mechanical device, and the corresponding output terminal of the control system is electrically connected to the driving end of the mechanical device, so that the control system controls the action of the mechanical device to drive The monitor is positioned so that ...

The invention discloses a fire extinguishing system for rapidly and accurately detecting the ignition point. The fire extinguishing system comprises an automatic water cannon, a control system and a sensor array. The automatic water cannon comprises a mechanical device and a water cannon. The control system controls positioning, starting and stopping of the water cannon through the mechanical device. The sensor array is composed of a plurality of sensor modules which are arranged on the indoor top face. Each sensor module covers the 1-4 m<2> of top face area, and the line spacing and row pitch between the sensor modules are both 1-2 m. Each senor module comprises a microprocessor, an infrared flame detector and an ultraviolet flame detector. The ultraviolet flame detectors are connected with the input ends of the microprocessors, the microprocessors are in both-way connection with the infrared flame detectors, the output ends of the microprocessors are electrically connected with the input end of the control system, the heads of infrared pipes of the infrared flame detectors are arranged right in the lower portion, and the heads of ultraviolet light sensitive tubes of the ultraviolet flame detectors are arranged right in the lower portion. Compared with the prior art, the ignition point can be rapidly and accurately determined.
Description
technical field [0001] The invention relates to the field of fire protection, in particular to a fire extinguishing system for rapidly and accurately detecting fire points. Background technique [0002] The automatic water cannon can automatically locate the fire point and extinguish the fire, so it is often used in large places such as airports and shopping malls. At present, the fire extinguishing system of the automatic water cannon mainly relies on sensors such as cameras, infrared tubes, and ultraviolet photosensitive tubes when locating the fire point. However, if figure 1 As shown, when there are reflective objects such as mirrors and glass in the fire place, the sensor often cannot distinguish between the original image and the mirror image, causing the automatic water cannon to locate the fire point to the mirror image to extinguish the fire. Become a big fire, bring great damage to personal safety, bring great loss to personal property and social public property....
