[0002] Whether it is in the construction period or the operation and maintenance period, the safety protection of personnel is essential. At present, in addition to strengthening safety education and equipping sufficient safety equipment at the construction site, other control measures are limited. Due to the weak self-safety awareness and low comprehensive quality of the operators, the wearing of safety equipment such as helmets, safety belts, life jackets, reflective vests, etc. is not standardized, or even not worn at all, which will inevitably lead to frequent safety accidents; unsafe behaviors such as smoking exist during the on-site construction process, which can easily cause risks such as fires and have serious impacts on society and the economy.

[0003] At present, terminal intelligent manufacturers have developed wearable devices such as smart helmets and smart seat belts. Such intelligent devices can impose certain constraints on operators and improve the comprehensive management level of the construction site. However, such devices have disadvantages such as high initial investment, high damage rate of positioning modules during on-site use, and high subsequent maintenance costs.

[0004] At present, the digital construction of engineering is in full swing, the construction of engineering site monitoring system is perfect, and the coverage of important scenes is very high. Personnel recognition technology based on image analysis is becoming more and more mature, and it can effectively identify unsafe behaviors of on-site personnel, such as improper wearing of safety equipment such as helmets and safety belts, fighting, smoking, not wearing masks and other unsafe behaviors. However, due to problems such as personnel angle and video clarity, the accuracy and efficiency of face recognition are insufficient, and the system cannot accurately determine identity information, and cannot make timely and accurate warnings and records.

[0005] The Chinese patent publication number is CN114399552B, and the publication date is April 26, 2022. The name of the invention is a method for behavior recognition and positioning in an indoor monitoring environment. The application discloses the use of multi-angle and multi-source data to identify the behavior of the detection object and locate the head, so as to determine the accurate behavior category of each detection object, so as to achieve effective intelligent monitoring of the behavior of the care recipient in the indoor monitoring environment. The disadvantage is that at the construction site, personnel usually wear safety helmets and protective masks, and accurate object detection cannot be performed through image recognition. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the analysis and alarm system based on behavior recognition and spatial positioning provided by the present invention. Implementation

[0013] The present invention is further described in detail below with reference to the accompanying drawings and specific examples.

[0014] The analysis and alarm system includes a monitoring system 1, a graphic processing module 2, an intelligent work badge 3, an intelligent analysis system 4 and an alarm system 5.

[0015] The monitoring system 1 monitors the construction site to generate a video stream 10. The input end of the graphics processing module 2 receives the video stream 10 and outputs an unsafe behavior code and location information 20. The smart work badge 3 includes identity information and location information 30. The intelligent analysis system 4 receives the unsafe behavior code and location information 20 and the identity information and location information 30. The intelligent analysis system 4 outputs an unsafe behavior record 40 and inputs it into the alarm system 5, which executes alarm actions such as broadcasting and voice calls.

[0016] When the system is working, the monitoring system 1 generates a video stream 10, which is transmitted to the graphics processing module 2. The graphics processing module 2 performs video segmentation, video compression, frame extraction and other operations on the video stream 10 to obtain a key frame image, and then performs image preprocessing through image ROI, image filtering, denoising, image binarization and other operations. The graphics processing module extracts features from the preprocessed image to obtain pixel value features, optical flow information features, edge features, etc. The data set after the feature value extraction is input into the behavior recognition deep neural network model, and the unsafe behavior of the personnel in the video stream is calculated and identified. The unsafe behavior is encoded according to the existing unsafe behavior encoding library. At the same time, the positioning deep neural network model in the graphics processing module can identify the coordinates of the personnel's location, and the unsafe behavior encoding information 20 with coordinate information is input into the intelligent analysis system 4; the smart work badge 3, which can be transmitted through ultra-wide band (UWB) or radio frequency identification (RFID) The intelligent analysis system 4 uses RFID (Radio Frequency Identification) technology to upload the identity information and location information of the personnel in real time to the intelligent analysis system 4 30; the intelligent analysis system 4 combines various types of input information, compares the location information transmitted by the graphic processing module and the smart work badge, and thus determines the identity information of the personnel of the unsafe behavior identified by the graphic processing module, and assigns the unsafe behavior information obtained by the graphic processing module to the personnel, and generates a record 40 in the system; at the same time, the intelligent analysis system 4 transmits the information to the alarm system 5, and the alarm system 5 warns the personnel through broadcasting, calls, and other methods.

[0017] The present invention imports the information flow generated by behavior recognition and spatial positioning into the intelligent analysis system. Through analysis, the identity information and the unsafe behavior of the person can be determined, and the personnel can be warned in time, thereby improving the safety management level of the engineering site, reducing the occurrence of safety accidents, and directly and indirectly improving economic benefits, which has a promotional effect.

[0018] The above description is only used to illustrate a specific implementation case of the present invention, and is not used to limit the applicable scope of the present invention. All equivalent changes or modifications made by those skilled in the art without departing from the spirit and principle of the present invention shall still be covered by the scope of the claims of the present invention.
