[0043] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] The utility model provides an intelligent safety belt based on UWB and GPS, comprising: a safety belt body and a host; the safety belt body comprises a fixing part and a hook part; the fixing part is provided with a buckle, suitable for being fixed to a user through the buckle; a hook is provided at one end of the hook part, and the other end is connected to the fixing part; the host is fixed on the fixing part, and comprises a microprocessor module, a GPS module, a UWB module, a detection module and an alarm module; the GPS module, the UWB module, the detection module and the alarm module are all electrically connected to the microprocessor module; and the detection end of the detection module is also electrically connected to the buckle and the hook.

[0045] It should be noted that the seat belt body is the part that the user directly contacts, and is divided into two parts: the fixing part and the hook part. The fixing part is designed with a buckle, through which the user can fix the seat belt to the body to ensure the stability of wearing. One end of the hook part has a hook for connecting to a fixed point (such as a building safety point, etc.), and the other end is connected to the fixing part to form a closed-loop protection system.

[0046] The host is installed on the fixed part of the seat belt and is the control center of the entire intelligent system. Among them, the microprocessor module serves as the brain, responsible for coordinating and processing data from various sensor modules, and responding or issuing instructions according to preset logic. The GPS module uses satellite signals to continuously provide the wearer's location information, which is essential for tracking, rescue and geo-fencing applications. Compared with traditional wireless communication technologies, UWB modules provide higher-precision distance and position measurements, which are suitable for close-range precision monitoring, such as determining whether the seat belt is closed normally and the distance between the user and a specific point. The detection module is directly connected to the buckle and hook to monitor the use status of the seat belt, such as whether it is worn and locked correctly. When the alarm module detects an abnormal situation (such as the seat belt is not worn correctly, the user exceeds the safety area, etc.), it issues a warning through sound, vibration or other means to alert the user or the monitoring center.

[0047] When the smart safety belt of this embodiment is actually used, the fixing part is first worn on the user and fixed by the buckle. Then the hook part is fixed to a safe point in the working environment by the hook. The detection module of the host detects the connection status of the buckle and the hook. If both are connected, a corresponding signal is sent. After the microprocessor module receives the signal from the detection module, it determines that the safety belt is in use, and then further obtains GPS positioning information and ranging information through the GPS module and the UWB module. When the user is in an area with a good GPS signal, the microprocessor analyzes the GPS positioning information with the preset dangerous working area. When the user's GPS positioning information shows that he is in a dangerous working area, an alarm signal is sent through the alarm module. Since there may be areas with poor GPS signals in the working environment, the microprocessor module uses the ranging information of the UWB module to determine the distance between the user and the dangerous target. When this distance does not meet the definition of the safe distance, a corresponding alarm signal is sent through the alarm module.

[0048] See also Figure 1 , Figure 1 A structural design scheme of an intelligent safety belt is shown. Figure 1 Some embodiments of the utility model are introduced.

[0049] like Figure 1 As shown, in some embodiments, the fixing part includes: a fixing belt body and a buckle. The fixing belt body includes a waist fixing belt 1, a shoulder fixing belt 2 and a back fixing belt 3; the waist fixing belt 1 is ring-shaped; one end of the shoulder fixing belt 2 is fixedly connected to the waist fixing belt 1, and the other end is fixedly connected to one end of the back fixing belt 3; the other end of the back fixing belt 3 is fixedly connected to the waist fixing belt 1; the buckle is set on the shoulder fixing belt 2. The host 4 can be fixed on the shoulder fixing belt 2.

[0050] It can be understood that the waist fixing belt 1, the shoulder fixing belt 2 and the back fixing belt 3 are used to be fixed on the waist, shoulders and back of the user respectively, so that the smart safety belt provided in this embodiment can be tightly fixed on the user to ensure the safety of the user.

[0051] like Figure 1 As shown, in a further embodiment, the shoulder fixing strap 2 and the back fixing strap 3 each include two fixing straps; the two fixing straps of the shoulder fixing strap 2 are symmetrically arranged, and one end of the two fixing straps in the same direction is fixedly connected to the first connecting portion of the waist fixing strap 1, and one end in the other direction is respectively connected to one end of the two fixing straps of the back fixing strap 3; the two fixing straps of the back fixing strap 3 are cross-arranged, and the other ends of the two fixing straps are fixedly connected to the second connecting portion of the waist fixing strap 1; the first connecting portion and the second connecting portion are arranged at opposite ends of the waist fixing strap 1.

[0052] It should be noted that the shoulder strap 2 has two symmetrical straps, which means that they are designed to surround and support the shoulder area in a balanced manner. This design helps to evenly distribute pressure, reduce the sense of oppression in a single position, and increase stability. One end of the two straps is connected to the first connection part of the waist strap 1, which means that the support of the shoulders will receive additional stability support through the waist, helping to maintain the correct body posture. The back strap 3 adopts a cross design. This layout can form a stable network on the back and strengthen the support for the spine. The two ends of the two straps are connected to the two ends of the waist strap 1 (the first connection part and the second connection part) respectively. This connection method can ensure that the fixation of the entire back and shoulders is linked and balanced, which helps to maintain overall stability and adjust the body posture. The waist strap 1 serves as a bridge connecting the shoulder and back straps 3. Its first connection part and the second connection part are located at opposite ends. This design allows the user to adjust the tightness of each part according to their body shape and needs to achieve the best fixation effect. The waist strap 1 not only provides an important support point, but also helps to disperse the pressure on the shoulders and back, reducing the burden on these areas.

[0053] like Figure 1 As shown, in some embodiments, an auxiliary fixing belt 5 is further included; two ends of the auxiliary fixing belt 5 are symmetrically fixed on the two fixing belts of the shoulder fixing belt 2.

[0054] In some embodiments, the hook 6 portion includes: two hook bodies. The two hook bodies are both provided with a hook 6 at one end in the same direction, and the other end is fixedly connected to the fixing portion.

[0055] See also Figure 2 , Figure 2 A module design scheme of a host is shown. Figure 2 Some embodiments of the utility model are introduced.

[0056] like Figure 2As shown, in some embodiments, the detection module includes: a use detection module; the use detection module includes a wearing detection module and a hook detection module; the detection end of the wearing detection module is connected to the buckle; the detection end of the hook detection module is connected to the hook. Further, the buckle adopts a car plug-in buckle, and the wearing detection module adopts a micro switch detection circuit. Further, the hook detection module adopts a photoelectric detection device. Further, the detection module also includes: an auxiliary detection module; the auxiliary detection module is a gyroscope device. Further, it also includes: a communication module. The communication module is electrically connected to the microprocessor module. Among them, the auxiliary detection module detects the movement information of the user after wearing the seat belt through the gyroscope device. Based on the movement information, the microprocessor module can comprehensively judge the use status of the seat belt in combination with the detection information provided by the detection module to prevent misjudgment. In addition, the microprocessor module can also communicate with external devices through the communication module to realize functions such as remote transmission of alarm signals.
