Abstract
The utility model discloses a track traffic vehicle-mounted fire disaster image alarming device which comprises a connecting in sequence an industrial grade high frequency area array camera, an image storage device, an image processing device, a communication device and an alarming device. The area array camera of the vehicle-mounted fire disaster image alarming device is fixed on the top portion of a train. 2-5 area array cameras with the same space are arranged in each train. Videos in a compartment are collected for a current time by the industrial grade high frequency area array camera. Smoke calculating arithmetic is carried out by the image processing device. Testing precision of the fire disaster is improved. Remote transmission of the videos and networking monitoring of the train are realized. The track traffic vehicle-mounted fire disaster image alarming device is low in cost, high in efficiency and good in expansibility.
Description
Technical field
The utility model relates to a kind of video image identification system of smog, especially relates to a kind of rail transportation vehicle-mounted fire image warning device, belongs to industrial automation.
Background technology
Along with the quickening of Urbanization Process In China, urban population increases severely, and the low pollution of development, low energy consumption, the For City Public Transportation System that capacity is large, speed is fast, safe are the effective ways that solves large-and-medium size cities public transport pressure.Vehicular system as urban public bus lines operation commander maincenter is the important guarantee of the safe, reliable, efficient operation of urban public bus lines.
Traditional track traffic fire prevention measure is used smoke detector, optical detector of fire smoke etc.And in most of occasions, the generation of fire hazard aerosol fog is early than the appearance of naked light, existing these detectors exist owing to the wrong report that the factors such as smog color, space size, air-flow, vibration cause, report late, and owing to the wrong report that dust accumulation and environmental change cause, the phenomenon such as failing to report, the characteristics such as the NA night alarm rate is low in addition.The track traffic image alarm system has very large using value in the track traffic detection.
Summary of the invention
The purpose of this utility model is exactly a kind of rail transportation vehicle-mounted fire image warning device that strong, the good extendability of a kind of low cost, general ability is provided in order to overcome the defective that above-mentioned prior art exists.
For achieving the above object, the utility model provides a kind of rail transportation vehicle-mounted fire image warning device, comprise the technical grade high frequency area array cameras, video memory, image processor, communication device and the alarm that connect successively, it is characterized in that: be provided with tight shot and infrared light sources on the described technical grade high frequency area array cameras.
Described technical grade high frequency area array cameras is connected with described video memory by the high-speed video bus.
Described technical grade high frequency area array cameras is fixed on the train top by support, and every joint train is provided with 2-5 with spacing.
Described video memory links to each other by the high-speed video line with image processor.
Described image processor links to each other by data line with alarm with communication device.
Described communication device links to each other with the cable TV on train supervisory system.
Concrete, technical grade high frequency area array cameras, video memory, image processor, communication device and alarm described in the utility model all can adopt known schemes of the prior art, relevant above-mentioned known solution, those skilled in the art all understands, does not repeat them here.
Description of drawings
Fig. 1 is hardware configuration schematic diagram of the present utility model;
Fig. 2 is process flow diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of rail transportation vehicle-mounted fire image warning device, comprise the technical grade high frequency area array cameras 1, video memory 2, image processor 3, communication device 4 and the alarm 5 that connect successively, it is characterized in that: be provided with tight shot and infrared light sources on the described technical grade high frequency area array cameras 1.
Described technical grade high frequency area array cameras 1 is connected 2 by the high-speed video bus with described video memory.
Described technical grade high frequency area array cameras 1 is fixed on the train top by support, and every joint train is provided with 2-5 with spacing.
Described video memory 2 links to each other by the high-speed video line with image processor 3.
Described image processor 3 and communication device 4 and alarm 5 link to each other by data line.

As shown in Figure 2, workflow of the present utility model is as follows:
101,1 pair of image of technical grade high frequency area array cameras carries out continuous acquisition, and view data is passed through the high-speed video bus transfer to video memory 2.
102, video memory 2 memory images, and view data is transferred to image processor 3 by the high-speed video line, the consecutive image data of 3 pairs of collections of image processor are carried out noise reduction process.
103, behind the noise reduction, this image processor 3 adopts topography to compare to eliminate redundancy.
104, eliminate redundancy after, this image processor 3 is processed by image, and the image that gathers is carried out frame by frame difference, and is that statistical study is carried out in many zonules with the result images cutting.Adopt Snake energy model algorithm and AdaBoost sorting algorithm that image is processed in real time, video data is peeled off into frame by frame picture, current data frame is demarcated unusually.Extraction for static and color characteristic need to reconstruct background image by the Background Reconstruction algorithm from successive frame, then use background difference, gaussian filtering, area filling scheduling algorithm to carry out cutting apart of target area, then extracts feature analysis.
105, video memory 2 is stored the view data that gathers, and supports follow-up historical video playback.
106, alarm 5 carries out Realtime Alerts.
107, communication device 4 shows the view data that gathers in real time by the Control Room that the cable TV on train supervisory system sends to train.
Compared with prior art, the utility model has improved the evaluation degree of accuracy of fire, can realize the long-distance transmissions of video and the networked control of train, and low-cost, high-level efficiency have good extendability.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
