[0003] Safety belts are the core protective equipment for ensuring the safety of personnel in high-altitude and high-altitude operations, and their correct use is the key to preventing falls from heights.

[0004] In the prior art, such as the intelligent safety belt device disclosed in the patent with publication number CN210057200U, although the sensor group in the chest protection plate realizes the detection of environmental parameters (such as temperature, humidity and wind speed), and improves the flexibility of operation by means of telescopic belt and retraction mechanism;

[0005] However, no auxiliary reminders or alarm functions are set up for the usage status; when users engage in illegal operations such as hanging the hook empty or placing the hook too low, they cannot receive timely warnings. If they are not intervened in time, it is very easy to cause a fall accident, resulting in personal injury or death.

[0006] Therefore, an intelligent seat belt device that can monitor usage status in real time and provide proactive reminders is proposed to compensate for the shortcomings of traditional seat belts in safety supervision. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-4This utility model provides an intelligent seat belt device, including a back strap body 100, on which a seat belt assembly 200 is provided, and a detection unit is provided on the seat belt assembly 200; the seat belt assembly 200 includes a seat belt webbing 210 and a hook 220, one end of the seat belt webbing 210 is connected to the back strap body 100, and the other end of the seat belt webbing 210 is connected to the hook 220; the detection unit includes a first infrared sensor 300 and a second infrared sensor 400, both of which are disposed on the hook 220. If either the first infrared sensor 300 or the second infrared sensor 400 fails to detect a valid signal, the hook 220 is determined to be in an unattached or unlocked state. A host 500 is installed on the main body 100 of the shoulder strap. The first infrared sensor 300 and the second infrared sensor 400 are electrically connected to the host 500. The host 500 integrates a positioning module, an information transmission module, a three-dimensional spatial sensing module, and an audible and visual alarm module. The positioning module, information transmission module, three-dimensional spatial sensing module, and audible and visual alarm module are connected to the host 500. The host 500 can be equipped with an ARM Cortex-M series MCU as the main control core. Through the main body 100 of the shoulder strap, the safety belt assembly 200, the detection unit, and the host 500 integrating positioning, information transmission, three-dimensional spatial sensing, and audible and visual alarm modules, the basic structure of the intelligent safety belt is constructed, realizing the initial monitoring, alarm, and information synchronization functions of the hook 220's usage status, and providing a core framework for subsequent detailed functions.

[0031] The hook 220 includes a connecting ring 221, a hook body 222, a locking part 223, and a limiting part 224. The hook body 222 is connected to the end of the seat belt webbing 210 through the connecting ring 221. The locking part 223 and the limiting part 224 are rotatably connected to the hook body 222 through pins. The first infrared sensing device 300 is fixedly connected to the outer surface of the hook body 222 by a high-temperature resistant adhesive and a metal pressure plate, and is used to detect whether the hook body 222 is hooked on an object. The second infrared sensing device 400 is fixedly connected to the outer surface of the locking part 223 in the same way, and is used to detect whether the locking part 223 is in a locked state. This allows the sensing devices to accurately correspond to the hooking and locking actions of the hook 220, improving the pertinence and accuracy of detecting the hook's empty or unlocked state.

[0032] Both the first infrared sensing device 300 and the second infrared sensing device 400 employ infrared proximity sensors. The infrared proximity sensor on the hook body 222 can be a HEG-LPR-01-R model, which directly determines the hooking status through level signals, has strong anti-interference capabilities, and is suitable for complex high-altitude operation environments. The infrared proximity sensor on the locking part 223 can be a Si1102-A-GM model, which uses its threshold reflection principle to identify the mechanical positioning status of the locking part without MCU intervention, reducing the load on the host 500. Utilizing its sensitive detection characteristics of object proximity status, it improves the reliability of detecting whether the hook 220 is hooked on an object and whether the locking part 223 is locked, reducing false or missed judgments.

[0033] The three-dimensional spatial sensing module uses either a three-axis accelerometer or a gyroscope to accurately detect the spatial positional relationship between the seat belt assembly 200 and the host 500. The three-dimensional spatial sensing module can use a three-axis gyroscope of model ER-3MG-041. Through its accurate perception of spatial positional relationships, it can reliably identify the relative position of the seat belt assembly and the host, ensuring that the alarm can be accurately triggered when the hook 220 is too low.

[0034] The positioning module uses a GPS module or a Beidou positioning module, while the information transmission module uses a 4G and Bluetooth wireless communication module. The former ensures the stable acquisition of device location information, while the latter enables efficient and multi-scenario transmission of alarm information to the terminal, such as long-distance 4G transmission or short-distance Bluetooth linkage, thus improving the feasibility of remote management.

[0035] The sound and light alarm module includes a buzzer and a warning light, both of which are exposed on the surface of the main unit 500 housing. Through dual warnings of sound and sight, it can ensure that users can quickly perceive violations in noisy working environments, thus enhancing the reminder effect.

[0036] The outer surface of the main unit 500 housing is provided with a QR code identification area 510. The QR code on the QR code identification area 510 is associated with the positioning module. Information can be entered and matched with the device by scanning with a mobile terminal, which simplifies the information entry and matching process of the device, facilitates the rapid association management of the device, user and location, and improves the convenience of device use and management.

[0037] The main unit 500 is equipped with a rechargeable lithium battery inside its housing. The main unit 500, positioning module, information transmission module, three-dimensional spatial sensing module, and sound and light alarm module are all connected to the rechargeable lithium battery. The main unit 500 housing is equipped with a charging interface. This ensures continuous power supply to the main unit 500 and each module, adapts to the needs of long-term outdoor operation, avoids the inconvenience of frequent battery replacement, and improves the equipment's endurance.

[0038] The seat belt webbing 210 and the back strap body 100 are provided with a wire channel. The first infrared sensor 300 and the second infrared sensor 400 are electrically connected to the main unit 500 through wires passing through the wire channel. This realizes a concealed electrical connection between the first infrared sensor 300, the second infrared sensor 400 and the main unit 500, avoiding wear or tangling caused by exposed wires, and improving the durability and safety of the smart seat belt device.

[0039] The main unit 500's casing is made of ABS engineering plastic and has a waterproof coating, which is either a polyurethane waterproof coating or a polytetrafluoroethylene coating. The high-strength material ensures the structural stability of the main unit 500, while the waterproof coating enhances its adaptability to complex environments such as humidity and dust, thus extending the equipment's service life.

[0040] The working principle of this utility model is as follows:

[0041] Power-on matching: Scan the QR code in the QR code identification area (510) with a mobile terminal to complete the device information entry and matching; the positioning module starts synchronously, automatically associates the device location information, and can be put into use after successful matching;

[0042] Status monitoring and alarms:

[0043] Hook status detection: The first infrared sensor 300 detects in real time whether the hook 222 is hooked on an object, and the second infrared sensor 400 detects simultaneously whether the locking part 223 is in the locked state; if either sensor fails to detect a valid signal, the host 500 determines it to be in a violation state (empty hook or not locked) and immediately triggers the sound and light alarm module to issue a dual reminder through a buzzer and a warning light.

[0044] Position status detection: The three-dimensional spatial sensing module continuously detects the spatial position relationship between the seat belt assembly 200 and the host 500. When the hook 220 is lower than the host 500 (i.e., the position is too low), the host 500 will also trigger an alarm and synchronize the alarm information and the real-time position obtained by the positioning module to the preset terminal through the information sending module, so that the manager can respond quickly and stop the violation.

[0045] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
