Description

Technical Field

[0001] This utility model relates to the field of high-precision wireless positioning technology using wireless pulses, and in particular to a helmet-shaped positioning tag based on visual management. Background Technology

[0002] In the current safety management of complex working environments such as construction, industry, and mining, 3D visualization management systems have become core infrastructure. Through 3D modeling and real-time data fusion technology, they dynamically map physical space, equipment assets, personnel movement and work processes into interactive digital twins, significantly improving situational awareness and decision-making efficiency.

[0003] Independently operated positioning terminals and identity authentication systems force personnel to carry multiple types of equipment, which not only increases the operational burden but also causes a disconnect between the physical location and identity information in the 3D visualization environment. During emergency response, it is impossible to associate personnel attributes in real time, resulting in delays in evacuation command and rescue dispatch.

[0004] To address the aforementioned technological gaps, there is an urgent need for an innovative hardware platform that integrates high-precision 3D positioning and real-time identity recognition. This platform should overcome the spatial coordinate drift problem in complex environments and enable dynamic binding. Furthermore, existing positioning and identity recognition devices have shortcomings in their wearing methods. Some devices are bulky and uncomfortable to wear, hindering normal activities; while smaller devices suffer from short battery life and unstable signal transmission. Therefore, developing a personnel positioning tag that integrates high-precision positioning and multi-functional identity recognition, is convenient to wear, easy to operate, and has a stable signal, is of significant practical importance in meeting the needs of various industries.

Detailed Implementation

[0029] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a helmet-type positioning tag based on visual management, which can ensure that the normal use of the helmet is not affected while facilitating the wearer to track their location in real time, access control, and card payment. It includes: a tag 100, a connecting component 200, and an IC card 300; the tag 100 is set on the outer edge of the helmet through the connecting component 200, and the IC card 300 is connected to the main control circuit and set inside the tag 100 and electrically connected to the tag 100;

[0033] The connecting assembly 200 includes a connecting plate 201 on the safety helmet, a guide plate 206 on the label, an insert 202 on one side of the guide plate 206, and an unlocking component 205 on one side of the insert 202; the total axial superposition length of the guide plate 206 and the insert 202 is equal to the axial installation distance from the unlocking component 205 to the inner wall of the connecting plate 201.

[0034] Tag 100 is a Tb1000-h type micro tag 100, which is a new type of wireless pulse high-precision wireless positioning beacon device used to locate personnel wearing the tag 100. It has high-precision positioning and ranging accuracy up to 10cm level.

[0035] The tag 100 is worn by connecting to a safety helmet via a connector 200. It features a built-in omnidirectional antenna and rechargeable battery, supporting emergency distress alarms. It uses a universal magnetic charging interface, is easy to operate, and has a long standby time. It is simple to wear and convenient to use. In addition to high-precision positioning, the tag 100 can be equipped with an IC / ID card, replacing ordinary passive IC / ID cards for access control, card payment, and other functions.

[0036] The number of times tag 100 communicates with the base station per second is called the refresh rate of tag 100. By default, the refresh rate of tag 100 is 1Hz, which means it communicates with the base station once per second. In the LocalSense positioning system, this is represented by the parameter "refresh interval in milliseconds" (ms), and the relationship is: refresh interval in milliseconds = 1000 / refresh rate. For example, if you want to set tag 100 to refresh 3 times per second at a 3Hz refresh rate, the refresh interval should be set to 333ms. Sleep mode is a working mode designed to reduce the power consumption of tag 100. In sleep mode, the refresh rate of tag 100 is significantly reduced to reduce power consumption and extend standby time. When tag 100 is in sleep mode, the refresh interval increases to 10000ms, which means it sends a signal once every 10 seconds.

[0037] Tag 100 uses a vibration sensor to determine its own status and switches between sleep and positioning modes. To avoid frequent switching between sleep and working states, Tag 100 uses the following mechanism: if Tag 100 remains stationary for a period exceeding the time set by the "sleep delay," it enters sleep mode. The default sleep delay setting is 15 seconds. In real-world scenarios, when placed on a table or installed on a fixed, stationary object, it will enter this mode after 15 seconds. Upon detecting vibration, it immediately exits sleep mode. Generally, when worn by a moving person or installed on a moving device, vibration due to movement will cause it to exit sleep mode and enter normal positioning mode.

[0038] Furthermore, the label 100 is installed on the safety helmet via the connecting assembly 200. Since the total axial superposition length of the guide plate 206 and the safety plug 202 is equal to the axial installation distance from the unlocking component 205 to the inner wall of the connecting plate 201, the label 100 will be installed more tightly on the safety helmet.

[0039] Reference Figure 3 Furthermore, the connecting assembly 200 also includes a fixing rod 203 and a cavity 204; the fixing rod 203 is disposed on one side of the label 100, the cavity 204 is opened on the fixing rod 203, and the mounting plug 202 is disposed on one side of the fixing rod 203. The fixing rod 203 and the mounting plug 202 cooperate with each other, and the label 100 is fixed to the safety helmet by being inserted into the cavity 204 through the mounting plug 202.

[0040] Reference Figure 3 Specifically, the safety plug 202 includes a plug rod 202a, a rotating shaft 202b, and a spring 202c. The plug rod 202a is rotatably connected to the connecting plate 201 via the rotating shaft 202b. The plug rod 202a is Z-shaped, with one end being a pointed tip 202a-1 and the other end being a straight end 202a-2. The height of the pointed tip 202a-1 of the plug rod 202a is less than the width of the cavity 204. The spring 202c is located on one side of the pointed tip 202a-1 of the plug rod 202a and is connected to the safety cap.

[0041] The fixed rod 203 has a beveled edge 203a at its end, and the tip 202a-1 of the insertion rod 202a has a beveled surface 202a-3. A portion of the projection of the beveled edge 203a is located on the beveled surface 202a-3, and the area projected on the beveled surface 202a-3 is smaller than its projection area on the non-beveled surface 202a-3. When the operator inserts the fixed rod 203 on the label 100 into the connecting block, the fixed rod 203 will squeeze the insertion rod 202a when it is inserted into the connecting block. The insertion rod 202a will deflect due to the squeezing force. When the insertion rod 202a deflects, the tip 202a-1 will remain in contact with the side wall of the fixed rod 203 until the tip 202a-1 of the fixed rod 203 enters the cavity 204. The insertion rod 202a will then return to its original position. After returning to its original position, the fixed rod 203 will be subjected to radial squeezing force from the spring 202c, making the label 100 more securely installed.

[0042] Reference Figure 3 Furthermore, the connecting assembly 200 also includes an unlocking component 205, which includes a second spring 205a, a pressure rod 205b, and an unlocking block 205c. The second spring 205a is disposed on one side of the straight rod of the insertion rod 202a and connected to the safety helmet. The pressure rod 205b is disposed between the label 100 and the insertion rod 202a. The unlocking block 205c is disposed at the end of the connecting plate 201, and the end of the unlocking block 205c abuts against the end of the pressure rod 205b. The unlocking block 205c is made of elastic material. When the label 100 needs to be removed, the operator presses the unlocking block 205c inward. When the unlocking block 205c is pressed, it will move the pressure rod 205b into the connecting block. At this time, the pressure rod 205b presses down on the straight end 202a-2 of the insertion rod 202a, causing the insertion rod 202a to deflect. After deflection, the insertion rod 202a disengages from the fixed block, releases the limit, and pushes the label 100 outward under the elastic potential energy of the spring 202c.

[0043] Reference Figure 4 Specifically, the guide plate 206 is set on one side of the fixed rod 203. The width of the guide plate 206 is the distance from the side of the fixed rod 203 to the connecting plate 201. When installing the label 100, the operator only needs to align the side of the guide plate 206 with the side wall of the connecting plate 201 to complete the positioning. Furthermore, the alignment of the side of the guide plate 206 with the side wall of the connecting plate 201 ensures that the fixed rod 203 has no room to move after installation, making the label 100 installed tightly and stably.

[0044] Reference Figure 2 Furthermore, the indicator light 207 on label 100 forms a drive circuit with the main control circuit, and the button 208 forms a level detection circuit with the main control circuit;

[0045] The electrical drive circuit is configured to respond to the status control signal output by the main control circuit, and drive the indicator light 207 to display the device's operating status. The level detection circuit is configured to input a low-level alarm signal to the main control circuit based on the grounding action triggered by the alarm button 208 to activate the alarm circuit. The LED indicator light 207 on the tag 100 flashes once every 5 seconds to indicate the current battery level. When the flashing color turns red, it indicates that the battery is about to run out and needs to be charged as soon as possible. When charging, use the magnetic charging cable provided with the device. During charging, the LED indicator light 207 on the tag 100 should flash blue-green. After fully charged, the LED indicator light 207 on the tag 100 will remain solid green. When the alarm button 208 on the tag 100 is pressed, the tag 100 will upload an emergency distress alarm message. When the button 208 is pressed, the indicator light 207 on the tag 100 will flash orange, indicating that it is currently in distress alarm status.

[0046] Furthermore, Label 100 is made of polypropylene and has an IP67 protection rating, making it suitable for normal use in daily office work and in scenarios requiring a certain level of waterproofing.

[0047] Reference Figure 5 Furthermore, the IC card 300 includes a chip 301 and an induction coil 302. The induction coil 302 is magnetically coupled to the induction receiving end of the chip 301. It generates an induced electromotive force inside the chip 301 through electromagnetic induction. The radio frequency signal provides energy to the chip 301 through the induction coil 302 and realizes data transmission and interaction. The chip 301 is responsible for storing data, executing instructions and processing encryption algorithms.

[0048] Reference Figures 6-7 Furthermore, the IC card 300 is divided into 16 sectors, with each sector further divided into 4 data blocks. Each data block is 16 bytes in size. A sector is the basic unit of the IC card 300's storage structure. Each sector can be independently read / written and has access control. Multiple sectors allow for partitioned data storage, improving data security and management efficiency. Each sector contains 4 data blocks, making data storage more granular and facilitating individual operations on each data block. Each data block is 16 bytes in size, capable of storing a certain amount of information, ensuring both reasonable storage capacity and meeting the needs of fast read / write operations, as shown in the brown area in the diagram above. This is fixed by the chip 301 manufacturer and cannot be modified.

[0049] Working Principle: The tag 100 uses a connecting component 200 to connect with the safety helmet, ensuring stable wear in complex working environments without affecting the normal use of the helmet. The tag 100 has a built-in omnidirectional antenna, capable of receiving and transmitting signals from all directions, ensuring stable transmission of positioning signals. Furthermore, the tag 100 is equipped with a universal magnetic charging interface, making operation simple and quick; it automatically attaches and charges when near a charger, avoiding the damage caused by frequent plugging and unplugging of traditional charging interfaces. Functionally, the tag 100 not only has high-precision positioning capabilities, enabling real-time tracking of the wearer's precise location, but also has 300 built-in IC cards, enabling multi-functional applications such as access control and card payments. Simultaneously, the tag 100 supports an emergency alarm function. When the wearer encounters danger or an emergency, simply pressing the emergency button on the tag 100 will immediately send an alarm signal, notifying management personnel or the monitoring center, ensuring immediate rescue and providing comprehensive safety protection for the wearer.

[0050] The operator inserts the fixing rod 203 on the label 100 into the connecting block. During insertion, the fixing rod 203 presses against the insertion rod 202a, causing it to deflect. As the fixing rod 203 is inserted, the tip 202a-1 of the insertion rod 202a remains tightly fitted to the side wall of the fixing rod 203 until the tip 202a-1 of the fixing rod 203 is fully inserted into the cavity 204 of the connecting block. At this point, the insertion rod 202a recovers under its own elasticity. After recovery, the insertion rod 202a, under the radial compressive force of the spring 202c, presses against the fixing rod 203, thereby making the label 100 more securely installed. When it is necessary to remove the label 100, the operator presses the unlocking block 205c inward. During the pressing process, the unlocking block 205c pushes the pressure rod 205b into the connecting block. The pressure rod 205b presses down on the straight end 202a-2 of the insertion rod 202a, causing the insertion rod 202a to deflect again. After deflection, the insertion rod 202a disengages from the fixing rod 203, releasing the limitation on the fixing rod 203. At this time, under the action of the elastic potential energy of spring 202c, label 100 is pushed outward, thereby realizing the rapid removal of label 100.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
