The detection system can effectively detect fire hazards and reduce or avoid false fire hazard alarming simultaneously so as to save the cost. The detection system for fire hazard monitoring comprises a plurality of detection devices and a fire behavior analysis chip, wherein each group pf detection devices comprise at least two camera devices; one of the camera devices is an image photographing device and the other one is an infrared photographing device; and each group pf detection devices are all in signal connection with the fire behavior analysis chip. According to the detection system, a mode that the plurality of groups of detection devices are combined is adopted to cover a monitoring area; and meanwhile, each group of detection devices at least comprise image acquisition devices and infrared information acquisition devices; and the fire behavior is judged according to image information and infrared information, so that the judgment accuracy of the fire behavior is improved, and the cost is saved.
Description
Technical field
The utility model belongs to the fire alarm technical field, specifically, relates to a kind of detection system of fire monitoring.
Background technology
Along with the development of society, people are more and more deep to the understanding of fire, and each fire all is accompanied by the loss of material, and the disappearance of life; In order to reduce fire, particularly in public, a lot of AnBao Co., Ltd all are provided with fire detecting system, for detection of the condition of a fire, camera commonly is installed in public, prevent fire by artificial monitoring, this detection system need to have people's monitoring in 24 hours, and working strength is larger; And the condition of a fire is easy to just spread apart when occuring, if blind area or blind time period appear in monitoring, then easily causes fire; Occur for fear of this phenomenon, a lot of AnBao Co., Ltd also are provided with smoke detector in public, in case larger smog is arranged just reports to the police, but this warning is prone to the spurious alarm situation, as foggy weather appears, or people collective smoking etc., the loss that brings unnecessary human and material resources to fire-proof are arranged.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of detection system of fire monitoring is provided, and this detection system can effectively be surveyed the condition of a fire, reduces simultaneously or avoids false condition of a fire alarm condition to occur, and saves cost.
The technical solution adopted in the utility model is:
A kind of detection system of fire monitoring, comprise many group sniffers and a fire analysis chip, every group of sniffer comprises at least two camera heads, one of them of these two camera heads is image pickup device, another is the infrared pick-up device, and every group of sniffer all is connected with the fire analysis chip signal.
Further, every group of sniffer also comprises a far infrared induction installation.
Further, described image pickup device comprises low illuminance CCD camera.
Further, described infrared pick-up device comprises the CCD infrared camera.
Further, the detection system of described fire monitoring also comprises warning device, and warning device is connected with the fire analysis chip signal.
The beneficial effect that the utility model is obtained is: the utility model adopts the mode of many group sniffers combination to cover guarded region, every group of sniffer comprises image collecting device and infrared ray information collecting device at least simultaneously, judge the condition of a fire by image information and infrared information, the judging nicety rate of the condition of a fire is improved, and saves cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral is:
1---far infrared induction installation 2---infrared pick-up device
3---image pickup device 4---fire analysis chip
5---warning device.
Embodiment
Below in conjunction with accompanying drawing 1 and embodiment the utility model is described further.
Embodiment: referring to Fig. 1.
A kind of detection system of fire monitoring, comprise many group sniffers and a fire analysis chip 4, every group of sniffer comprises at least two camera heads, one of them of these two camera heads is image pickup device 3, another is infrared pick-up device 2, and every group of sniffer all is connected with fire analysis chip 4 signals.
The utility model adopts many group sniffers, sniffer is distributed in the regional in monitoring location, in each zone, adopt at least two cameras to monitor, survey respectively image and infrared ray in this zone, and image analoging signal and infrared ray simulating signal in should the zone pass to analytical equipment, analytical equipment is distinguished in conjunction with two kinds of signal analyses, can in time report to the police to the condition of a fire, and reduce the warning probability of the false condition of a fire.As when the red substrate of the image in this zone is more, compare in conjunction with infrared ray information again, if show the rising of the temperature anomaly in this zone, then the condition of a fire appears in explanation.If there is not temperature to rise, may be red object in the zone, avoid the false condition of a fire to report to the police.Secondly the utility model is provided with fire analysis chip 4, after obtaining field data, directly analyzes, and need not to communicate information to control center and analyzes, and reduces signal passing time distance, avoids signal to be interfered.Result after fire analysis chip 4 is analyzed passes to control center together with image video signal.
Further, every group of sniffer also comprises a far infrared induction installation 1.
Far infrared induction installation 1 is set, can further differentiates for flame; Because smoke at ordinary times, use lighter, the operation such as kindle incense all can detect to infrared camera, therefore might process in the mode of false condition of a fire newspaper; The far infrared inductor can be differentiated for these situations, can further reduce the spurious alarm situation.
Further, described image pickup device 3 comprises low illuminance CCD camera.
Adopt low illuminance CCD camera, can be in the darker situation of light environment being carried out image taking, wherein, the CCD lowest illumination be (lux) 3, hangs down illuminance here and refers generally to illuminance less than 20 lux.In the present embodiment, image pickup device 3 is diameter 14, the low illuminance CCD SD pick-up lens of 1,300,000 picture numbers, and it can adapt to the strong and weak light of varying environment, greatly strengthens gathering the color image information ability.
Further, described infrared pick-up device 2 comprises the CCD infrared camera.
Adopt the CCD infrared camera can improve imaging pixels.
Further, the detection system of described fire monitoring also comprises warning device 5, and warning device 5 is connected with fire analysis chip 4 signals.
After warning device 5 was set, detection system can be carried out first onsite alarming, the on-the-spot people of prompting put out the fire or away from, reduce the loss.Warning device 5 can be the acoustic alarm device, also can be the light warning device, also can be for acoustic alarm device and light warning device integrated.
Below only be the application's preferred embodiment, equivalent technical solutions on this basis still falls into the application protection domain.
