[0070] It should be noted that, in this embodiment, the settings of the camera 206, microphone 207, fill light 208, indicator light 209, various interfaces and button positions can be adjusted according to actual conditions. The present invention is not limited to one position layout of the above embodiment, and other position layouts are also protected by the present invention.

[0071] The embodiment of the present invention discloses a method for using a split-type intelligent safety helmet, comprising:

[0072] The audio and video module collects the video stream of the work site, the voice signal and video request of the worker wearing the helmet, the GPS positioning module collects the location information of the worker wearing the helmet, and the environmental perception module collects the acceleration information and environmental information of the worker wearing the helmet;

[0073] The control module receives the video stream of the work site, the voice signal of the worker wearing the safety helmet, the position information, acceleration information and environmental information of the worker wearing the safety helmet, and processes and analyzes the video stream of the work site to determine whether the worker wears the safety helmet and / or the safety belt, and sends the video stream of the work site, the voice signal of the worker wearing the safety helmet, the video request, the position information, acceleration information, environmental information and the position information of the worker wearing the safety helmet and / or the safety belt to the remote terminal through the communication module, and temporarily stores the video stream, position information and environmental information of the work site in the storage module when the network signal is not smooth, and continues to upload when the network is restored;

[0074] The remote terminal can display the video and location information of the work site in real time, and can issue voice commands or video requests to on-site workers.

[0075] For example, when an incorrect wearing method is detected, the result will be reported to the remote terminal. The remote control terminal can issue voice commands to the on-site workers, play voice commands through the audio and video module, and warn them to wear correctly. Voice commands do not only refer to voice warnings, but also remote voice communication when the helmet is worn correctly. That is, the remote control terminal can actively initiate a video request, and when the worker wearing it has a need, he can also initiate a video request through the button on the side of the smart terminal and talk to the remote terminal. Another main function is that when the built-in model of the smart terminal automatically analyzes that there is a dangerous behavior of incorrectly wearing a helmet or safety belt at the work site, the split smart helmet will also automatically broadcast a voice reminder to regulate the wearing of workers' protective equipment.

[0076] Preferably, Figure 8 As shown, the video stream of the work site is processed to determine whether the workers on site are wearing safety helmets and / or safety belts, specifically including:

[0077] Preprocess the collected work site video stream, including spatial filtering, image enhancement, etc., to reduce interference from complex environments;

[0078] The preprocessed video stream is input into the lightweight YOLO model for target recognition, and the situation of workers wearing helmets and / or safety belts on site is output. Among them, the lightweight YOLO model can be a yolov8 model, which is a preset model, that is, it is trained in advance based on a large number of images of workers wearing helmets and safety belts according to the on-site operation conditions. The specific process is: the built-in model in the smart terminal automatically identifies the dangerous behavior of incorrectly wearing helmets or safety belts, and will promptly broadcast the voice, and upload the results to the remote terminal. The remote terminal can also remind the workers who do not wear helmets or safety belts correctly on site again according to the results output by the model. Broadcasting voice reminders directly through smart terminals is more timely, reducing the delay of network transmission.
