Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1 to 3, the construction site personnel safety warning system based on image recognition comprises a construction site image acquisition and warning information broadcasting device. Construction scene image acquisition uses high definition surveillance camera head and infrared imaging camera 1, and warning information reports device and adopts public address loudspeaker 2, and camera and public address loudspeaker 2 have been installed simultaneously on a support, constitute construction scene safety alarm system. The safety warning system can be placed near a dangerous area 3 on a construction site, the camera is aligned with the dangerous area 3 to be monitored, and a plurality of such devices can be placed in the construction site. The transmission of the video signal and the alarm voice signal can be wired transmission or wireless transmission, the device is powered by a wired cable during wired transmission, and the device is powered by a battery during wireless transmission.
The high-definition monitoring camera is used for acquiring a real-time clear image of a construction site and providing high-quality image information for face recognition and behavior analysis of a person 4 and judgment on whether the dangerous area 3 invades or not. The infrared camera is used for assisting in judging the behavior information of the human body when the field light is poor or the facial features of the person 4 cannot be identified, and the accuracy of the video image analysis of the whole system is improved.
The public address loudspeaker 2 is used for playing alarm information, and public address playing contents are automatic danger reminding contents and can also be the shouting contents of monitoring center personnel; the warning information can be played in a single device area, and can also be broadcast on the public address loudspeaker 2 of the whole construction site at the same time.
The system also comprises an image recognition control center. The image recognition control center is the central pivot of the whole safety alarm system, is responsible for inputting, processing and outputting information, and is mainly divided into four modules of information input, system setting management, image analysis and calculation and alarm information distribution.
The main function of information input is to enter basic information of the constructor 4, including basic information of name, sex, age, blood type and work category, and most importantly, the facial features and the morphological features of the constructor 4, which are used for the identification function of the subsequent constructor 4.
The system setting management is the system setting and personnel 4 management of the whole alarm system. The most important functions are planning the hazardous area 3, setting the hazardous actions of the area and setting the personnel involved in the construction 4.
The image analysis and calculation is the technical core of the whole alarm system, and bears the important responsibility of analyzing and judging the intrusion and the dangerous behavior of the dangerous area 3. The image analysis and calculation module receives image information of a high-definition camera of a construction site, is assisted by human body infrared information of the infrared camera, judges whether a person 4 approaches or acts dangerously in a current dangerous area 3 or not through leading-edge technologies such as face recognition, posture step recognition, artificial intelligence and deep learning, and automatically generates alarm information content. The level of the alarm information can be divided into two levels, which are respectively: firstly, entering a danger monitoring range, and paying attention to safety; approaching the dangerous area 3 or having dangerous behaviors, and immediately departing from the dangerous area 3 or stopping the dangerous behaviors.
The alarm information distribution can send alarm information of different levels to the public address loudspeaker 2 of the construction site, a manager terminal of the construction site and a monitoring large screen of a command center according to the setting, and related personnel 4 are prompted to pay attention to safety risks or go to the construction site to check on the spot.
The warning terminal of the warning information broadcasting device can also comprise three types of loud speakers 2 divided into a construction site, a construction site manager terminal and a large screen of a monitoring command center. The public address loudspeaker 2 on the construction site can prompt attention to safety; the construction site manager terminal can be intelligent equipment such as a mobile phone, and the construction site manager can take corresponding risk precautionary measures according to the received safety alarm information; the large screen of the monitoring command center can see a plurality of real-time videos and alarm information of a construction site, and command scheduling decisions can be made according to actual conditions of the site.
In summary, in a certain large power construction site, there are several high-voltage dangerous areas 3 that need to be kept at distance, and the specific implementation method of the scheme is as follows:
firstly, a person 4 file is required to be established in a management system, the person 4 file comprises basic information such as name, sex, age, blood type and work category, and facial features and physical features of the person 4 are required to be input, so that comparison data which is a good basis for the following face recognition and behavior and action recognition are obtained.
And then determining a plurality of dangerous areas 3 needing safety control on a construction site, placing one or more image acquisition and alarm information broadcasting devices near each dangerous area, and aligning the camera to the dangerous identification area.
In an image recognition control center, special software is used for adjusting the camera view of each path, then the shape outline of the dangerous area 3 is drawn in the view range of the camera, and an area which is larger than the dangerous area 3 and is used for ordinary level reminding can be drawn. For the area needing to identify the dangerous behavior action, the dangerous behavior action to be identified can be selected in a behavior action analysis library of the system.
Before the construction is started every day, the personnel 4 participating in the construction on the same day need to be added into the management system, so that the construction site is prevented from entering the irrelevant personnel 4.
The working process of the safety alarm system is that if the safety alarm system identifies that the safety alarm system does not belong to the added construction participants 4 in the monitoring range, alarm information is sent out, and a field construction manager can decide whether to check and process the safety alarm system according to the situation; if the public address loudspeaker 2 on the spot detects that a person enters the early warning range, the public address loudspeaker broadcasts the attention safety reminding information of the common level; if the detection identifies that the dangerous area 3 close to the preset dangerous area or the dangerous behavior acts, the warning information is issued at a plurality of terminals to remind the user of safety, and if the user can correctly identify who the user is, the name can be broadcasted, the behavior is recorded, so that the user can conveniently check in the later period and emphatically strengthen the awareness of safety risk prevention on the individual person 4.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the spirit of the present invention, and these modifications and decorations should also be regarded as being within the scope of the present invention.
