Description

Technical Field

[0001] This utility model relates to the field of positioning cap card technology, and in particular to a multi-source fusion positioning cap card. Background Technology

[0002] Safety helmets are crucial equipment used to protect the heads of personnel on construction sites.

[0003] However, existing safety helmets have certain limitations, the most significant being the lack of positioning functionality. Currently, single positioning technologies are insufficient to meet the needs of all scenarios. For example, while satellite navigation systems such as GPS or BeiDou perform excellently in outdoor environments, they become unusable indoors due to severe signal attenuation. This hinders effective location monitoring and management of personnel on-site, limiting the overall improvement in intelligence levels. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-source fusion positioning cap card in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-source fusion positioning cap includes a housing, in which a wireless communication module, a Bluetooth tag, a UWB tag, and a Beidou receiver are installed. It also includes a metal spring. Blind holes are formed around the bottom of the housing, and annular grooves are connected to the blind holes. The metal spring passes through the blind holes and engages with the annular groove. The annular groove and the metal spring are movably connected by a positioning post.

[0007] As a further description of the above technical solution:

[0008] The metal spring includes an integrally formed cap end, a ring post, and a flange. The ring post has a notch along its radial direction, and the flange is located on both sides of the free end of the ring post. The flange is engaged with the ring groove.

[0009] As a further description of the above technical solution:

[0010] The diameters of the cap end and the flange are both larger than the diameter of the blind hole.

[0011] As a further description of the above technical solution:

[0012] A compression spring is fixedly connected between the annular groove and the positioning post, and a positioning hole that mates with the positioning post is provided on the flange.

[0013] As a further description of the above technical solution:

[0014] A telescopic rod is inserted inside the compression spring, and the two ends of the telescopic rod are fixedly connected to the annular groove and the positioning post, respectively.

[0015] As a further description of the above technical solution:

[0016] The positioning post comprises an integrally formed hemisphere and a column. The hemisphere mates with a positioning hole, and the column is connected to a compression spring and a telescopic rod.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, when workers wear safety helmets equipped with helmet clips and move indoors or outdoors, the wireless communication module collects positioning data obtained from Bluetooth tags, UWB tags, and Beidou receivers, and uploads this data to the positioning server through the data transmission gateway. The positioning server further processes and calculates the received data, converts it into specific coordinate information, and pushes it to the application server. This processed location data will be displayed to users or administrators on the application platform to facilitate monitoring and management of workers' location information.

[0019] 2. In this utility model, firstly, pressure is applied from both sides of the ring post to compress the flange into the blind hole. Since the diameter of the flange is larger than the diameter of the blind hole, it will be forced to contract inward during the process of entering the blind hole. When the flange completely passes through the blind hole and reaches the position of the ring groove, it will unfold due to the elastic restoring force and engage with the ring groove. Secondly, when the cap clip is to be removed, the metal spring is rotated to disengage the hemisphere from the positioning hole. Then, the ring post is squeezed from both sides to compress the flange and remove it through the blind hole, which facilitates the disassembly and assembly of the cap clip.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7This utility model provides a technical solution: a multi-source fusion positioning cap clip, including a housing 1, which is connected to a safety helmet via a metal spring 4. The metal spring 4 includes an integrally formed cap end 41, a ring post 42, and a flange 43. A notch 4201 is formed on the ring post 42 along its radial direction. The flange 43 is located on both sides of the free end of the ring post 42. Blind holes 2 and annular grooves 3 communicating with the blind holes 2 are formed around the bottom of the housing 1. By applying pressure, the flange 43 of the metal spring 4 is compressed into the blind hole 2, and the flange 43 engages with the annular groove 3. The diameters of the cap end 41 and the flange 43 are both larger than the diameter of the blind hole 2. By applying pressure from both sides of the ring post 42, the flange 43 is compressed into the blind hole 2. Edge 43 is compressed into blind hole 2. Because its diameter is larger than that of blind hole 2, edge 43 is forced to contract inward during its entry into blind hole 2. When edge 43 completely passes through blind hole 2 and reaches the position of annular groove 3, it unfolds due to elastic restoring force and engages with annular groove 3. A compression spring 6 is fixedly connected between annular groove 3 and positioning post 5. A telescopic rod 7 is inserted inside the compression spring 6. One end of the telescopic rod 7 is fixedly connected to annular groove 3. Positioning post 5 consists of an integrally formed hemisphere and a column. The column is connected to the free end of compression spring 6 and telescopic rod 7. Positioning hole 4301 is provided on edge 43 to mate with hemisphere, increasing installation stability. To remove the cap clip, rotate metal spring 4 to disengage hemisphere from positioning hole 4301. Then, squeeze annular post 42 from both sides to compress edge 43 and remove it through blind hole 2.

[0031] Specifically, such as Figure 7As shown, the housing 1 houses a wireless communication module 8, a Bluetooth tag 12, a UWB tag 14, and a Beidou receiver 16. Multiple Bluetooth beacons 13 are deployed indoors. When workers wear helmets equipped with Bluetooth tags 12 and enter the indoor area, the Bluetooth tags 12 periodically scan the surrounding Bluetooth beacons 13 and calculate the distance to each beacon based on the received Bluetooth signal strength (RSSI). By analyzing the signal strength data from multiple Bluetooth beacons 13 and using algorithms such as triangulation, the worker's position is estimated, with a positioning accuracy typically of 3-5 meters. In critical areas requiring higher precision positioning, UWB beacons 15 are deployed. When workers wear helmets equipped with UWB tags 14 and enter these areas, the UWB tags 14 and UWB beacons 15 exchange timestamps and calculate Time-of-Flight (ToF) to obtain accurate distance information. Using data from multiple UWB beacons 15, multiple... The edge positioning algorithm calculates the precise location of the worker, with an accuracy of about 1 meter. When the worker is outdoors, the Beidou receiver 16 on the safety helmet receives signals from the Beidou satellite navigation system 17. Based on the received satellite signals, the Beidou receiver 16 calculates its own three-dimensional coordinates using the tri-sphere intersection principle. For a dual-band Beidou receiver, its outdoor positioning accuracy is about 3 meters. Whether indoors or outdoors, the wireless communication module 8 collects positioning data from the Bluetooth tag 12, UWB tag 14, and Beidou receiver 16, and uploads this data to the positioning server 10 through the data transmission gateway 9. The positioning server 10 further processes and calculates the received data, converts it into specific coordinate information, and pushes it to the application server 11. Finally, this processed location data is displayed to users or administrators on the application platform for monitoring and managing the worker's location information. Through this multi-layered, multi-technology integration approach, it adapts to various positioning needs from open outdoor to complex indoor environments, providing continuous and relatively accurate location services.

[0032] Working principle: In use, firstly, pressure is applied from both sides of the ring post 42 to compress the flange 43 into the blind hole 2. Since the diameter of the flange 43 is larger than the diameter of the blind hole 2, it will be forced to contract inward during the process of entering the blind hole 2. When the flange 43 completely passes through the blind hole 2 and reaches the position of the ring groove 3, it will unfold due to the elastic restoring force and engage with the ring groove 3. After that, when the staff wears the safety helmet with the helmet clip installed and moves indoors and outdoors, the wireless communication module 8 collects the positioning data obtained by the Bluetooth tag 12, UWB tag 14 and Beidou receiver 16, and uploads the data to the positioning server 10 through the data transmission gateway 9. The positioning server 10 further processes and calculates the received data, converts it into specific coordinate information and pushes it to the application server 11.

[0033] Finally, to remove the cap clip, rotate the metal spring 4 to disengage the hemisphere from the positioning hole 4301. Then, squeeze the ring post 42 from both sides to press the flange 43 and remove it through the blind hole 2, which facilitates the removal and installation of the cap clip.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
