[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model embodiment discloses a split-type smart safety helmet, such as Figure 1-4 As shown, it includes: a helmet body 1 and a smart terminal 2, wherein the smart terminal 2 is detachably connected to the helmet body 1;

[0035] The safety helmet body 1 includes a helmet body 101, a mounting base 102 fixed on the helmet body 101, and a mounting groove 103 provided on the mounting base 102;

[0036] The smart terminal 2 includes a terminal body 201, and an installation strip 202 is fixed to the back of the terminal body 201. The installation strip 202 is inserted into the installation slot 103.

[0037] This utility model enables the detachable installation of the safety helmet body 1 and the smart terminal 2 through the structure of the mounting strip 202 and the mounting groove 103.

[0038] In this embodiment, the terminal body 201 is also provided with a spring-loaded buckle 203, a limiting block 204, and a spring 205. The limiting block 204 is fixed to the bottom of the spring-loaded buckle 203. One end of the spring 205 abuts against the bottom surface of the hole on one side of the limiting block 204, and the other end abuts against the inner wall of the terminal body 201. A gap is provided on the terminal body corresponding to the front end of the limiting block 204 for the extension and retraction of the limiting block 204. During installation, the terminal body 201 is inserted into the mounting base 102 at the front end of the safety helmet from top to bottom. When the spring-loaded buckle 203 is closed, it will cause the front end of the limiting block 204 to extend out of the terminal body 201, and the limiting block 204 will be locked at the top of the safety helmet body slot 104. Figure 5 As shown; during disassembly, the spring-loaded latch 203 is pushed in the opposite direction to unlock and open, thereby causing the front end of the limit block 204 to retract into the terminal body 201. After unlocking, pulling upwards completes the disassembly. Figure 6 As shown.

[0039] In this embodiment, as Figure 7 As shown, the main body of the terminal is also equipped with a control module, an audio and video module, a communication module, a storage module, an environmental perception module, and a GPS positioning module. The control module is connected to the audio and video module, the communication module, the storage module, the environmental perception module, and the GPS positioning module, respectively.

[0040] The audio and video module is used to collect video streams from the work site, collect voice signals from workers wearing safety helmets, issue video requests, play voice commands, and receive video requests sent by remote terminals.

[0041] The GPS positioning module is used to collect the location information of workers wearing safety helmets;

[0042] The environmental perception module is used to collect acceleration information and environmental information of workers wearing safety helmets;

[0043] The control module controls the audio / video module, communication module, storage module, environmental sensing module, and GPS positioning module. It processes and analyzes the video stream from the work site to determine whether workers are wearing safety helmets and / or safety belts. The video stream, voice signals from workers wearing safety helmets, video requests, location information, acceleration information, environmental information, and information on whether workers are wearing safety helmets and / or safety belts are transmitted to a remote terminal via the communication module. It should be noted that the methods for processing the video stream and determining whether workers are wearing safety helmets and / or safety belts can all be implemented using existing technologies, and this utility model does not constitute any innovation.

[0044] The storage module is used to temporarily store video streams, location information, and environmental information at the work site when network signals are unavailable.

[0045] The safety helmet and safety belt are separate items. The safety helmet is worn on the head of the on-site worker, and the safety belt is worn on the body of the on-site worker. The audio and video module collects the wearing status of safety belts and safety helmets of other workers around them, including situations where only a safety helmet is required, or situations where both a safety helmet and a safety belt are required. Therefore, this utility model plays a role through mutual supervision.

[0046] The remote terminal can display real-time video and location information of the work site, and can issue voice commands or video requests to on-site workers.

[0047] For example, when incorrect helmet wearing is detected, the remote terminal can issue voice commands to workers on site. These commands are played through the audio-visual module, warning them to wear the helmet correctly. The voice commands are not limited to warnings; remote voice communication is also possible when the helmet is worn correctly. The remote control can initiate video requests, and workers can also initiate video requests via buttons on the side of the smart terminal to communicate with the remote terminal. Another key function is that when the smart terminal's built-in model automatically analyzes and identifies dangerous behaviors such as incorrect helmet or safety belt wearing at the work site, the split-type smart helmet will automatically issue voice reminders to standardize the wearing of protective equipment. Specifically, the video stream processing at the work site can be as follows: the smart terminal's built-in model (which can use the existing lightweight YOLO model) automatically identifies dangerous behaviors such as incorrect helmet or safety belt wearing, promptly issues voice reminders, and uploads the results to the remote terminal. The remote terminal can also use the model's output to remind workers who are not wearing helmets or safety belts correctly. Directly broadcasting voice reminders through the smart terminal is timely and reduces network transmission latency.

[0048] The audio-visual module includes a camera 206, a microphone 207, and a speaker. Both the camera 206 and the microphone 207 are located on the front of the terminal body 201, with the camera 206 positioned above the microphone 207. Both the mounting base 102 and the terminal body 201 have sound holes 3 on their contact surfaces, which correspond to the speakers to facilitate the wearer's reception of voice messages.

[0049] It is also equipped with a fill light 208 and an indicator light 209. Both the fill light 208 and the indicator light 209 are located in front of the terminal body 201. The fill light 208 is located below the microphone 207, and the indicator light 209 is located to one side of the fill light 208.

[0050] The environmental sensing module includes an accelerometer and an environmental sensor. The accelerometer is used to collect acceleration information of workers wearing safety helmets, and the environmental sensor is used to collect environmental information of workers wearing safety helmets. The environmental sensor includes, but is not limited to, temperature and humidity sensors, gas concentration sensors, and biosensors.

[0051] The communication module includes a 4G module, a 4G antenna, and a SIM card. The terminal body 201 has a Type-C interface at the bottom, TF card and SIM card interfaces on the right side, and three buttons on the left side for function selection and settings. Workers wearing smart safety helmets can also use the buttons on the side of the smart terminal to select functions such as taking photos, lighting, initiating voice requests to remote terminals, and alarms, according to their needs. Specifically:

[0052] Button 1:

[0053] Power on: Press button 1. A "beep" sound indicates that the device has started successfully. The blue indicator light will flash, and the device will begin connecting to the network.

[0054] Power off: Press and hold button 1 for three seconds until a long beep sounds, then the device will be off.

[0055] Initiating a voice request: After the device is powered on, press button 1 briefly once. You will hear a "beep" sound and enter intercom mode.

[0056] Button 2:

[0057] Taking a picture: After the device is powered on and running normally, press button 2 briefly. A "beep" sound will be heard. At this time, the camera will start taking a picture and save a picture to the SD card.

[0058] Turn on the fill light: After the device is powered on, the fill light is off by default. Press and hold button 2 to activate the fill light to deal with shooting environments with insufficient light. Release the button after hearing a "beep" sound, and the fill light will turn on.

[0059] Button 3: After the device is powered on, press and hold button 3 to trigger a one-click alarm, and the device will immediately upload the alarm information.

[0060] It should be noted that, in this embodiment, the positions of the camera 206, microphone 207, fill light 208, indicator light 209, various interfaces, and buttons can be adjusted according to actual conditions. This utility model is not limited to the position layout of the above embodiment, and other position layouts are also protected by this utility model.
