[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] Reference Figures 1-8 As shown, a transportation management system based on BeiDou positioning mainly consists of a steel structure transportation tracking system terminal based on BeiDou positioning, a mobile app, a BeiDou chip 5, and a fixed card 4. The BeiDou chip 5 is bound to the steel structure component or its transport vehicle through the fixed card 4. The transportation process of the steel structure component can be identified and tracked in real time through the mobile app, and the transportation information can be synchronized to the steel structure transportation tracking system terminal in real time, thus forming an integrated steel structure tracking system based on BeiDou positioning.

[0036] The BeiDou-based steel structure transportation tracking system terminal mainly refers to the PC / web terminal. Its main function is to facilitate the back-end management to view the transportation status of steel structure components in real time. It integrates functional modules such as component list import and export, big data dashboard, individual component details, and special status warnings.

[0037] The mobile app is equipped with a Beidou communication system and Bluetooth connectivity. Its main function is to transmit information about steel structure components to the transportation tracking system terminal in real time by identifying the Beidou positioning chip. The app's interface and functional modules can be customized according to project requirements.

[0038] The Beidou positioning chip incorporates Beidou satellite positioning technology and integrated navigation technology, enabling real-time high-precision three-dimensional positioning and speed measurement. It can effectively locate in areas with weak or no satellite signals, such as jungles, tunnels, and underground parking lots.

[0039] Its specific structure includes:

[0040] Frame 2 is fixed to steel component 1 by fasteners 3, or by bolts or other mounting components;

[0041] Fixed card 4 is set inside frame 2, and Beidou chip 5 is installed inside fixed card 4. When the transport vehicle moves, it will shake to a certain extent, and fixed card 4 can move back, forth and left and right inside frame 2.

[0042] The fixing frame 7 is set inside the frame 2. The fixing frame 7 can move back and forth relative to the frame 2, while the fixing clip 4 can move left and right relative to the fixing frame 7. When the fixing frame 7 moves back and forth, it will also force the fixing clip 4 to move left and right. When the fixing frame 7 moves forward, the fixing clip 4 moves to the left.

[0043] Two protective sleeves 6 are respectively set on both sides of the fixed card 4 and slidably connected to the fixed frame 7 to protect the fixed card 4. When violent movement such as impact occurs, the speed will change significantly. At this time, the fixed card 4 will shake significantly, so that the fixed card 4 can be directly inserted into the protective sleeve 6 to protect the Beidou chip 5.

[0044] Initially, the Beidou chip 5 was not inserted into the protective sleeve 6 and was in a relatively exposed state. When the Beidou chip 5 is working, it can generate a certain heat dissipation effect. After the Beidou chip 5 is subjected to a large impact, it can be inserted into the protective sleeve 6 for protection.

[0045] The buffer component 8 is located between the fixing card 4 and the protective sleeve 6 to buffer the fixing card 4 and reduce the shaking of the Beidou chip 5.

[0046] The limiting rod 9 is rotatably mounted on the buffer assembly 8 and is used to push the buffer assembly 8 so that when the fixing frame 7 moves back and forth, it can drive the fixing card 4 to move left and right.

[0047] In one embodiment, positioning plates 41 are movably provided at both ends of the fixing card 4, positioning components 42 are provided at the four corners of the fixing card 4, a first slot that cooperates with the fixing card 4 is provided inside the protective sleeve 6, and a second slot located on one side of the first slot is provided inside the protective sleeve 6, and the second slot cooperates with the positioning plates 41.

[0048] Initially, the positioning plate 41 is partially located inside the fixing card 4 and is fixed by the positioning component 42. After the fixing card 4 is inserted into the first slot, the positioning component 42 is opened, and then the positioning plate 41 is inserted into the second slot.

[0049] In one embodiment, the positioning component 42 includes a positioning rod 421 inserted into the fixing card 4. The positioning rod 421 is inserted into the positioning plate 41. A guide plate 422 is provided at one end of the positioning rod 421. A pressure plate 423 is provided on the positioning rod 421 and located inside the fixing card 4. A first limiting spring 424 sleeved on the positioning rod 421 is provided on one side of the pressure plate 423. A guide groove 620 that cooperates with the guide plate 422 is also provided in the protective sleeve 6. The guide groove 620 is inclined and gradually moves away from the first slot.

[0050] After the fixing card 4 is inserted into the protective sleeve 6, the guide plate 422 will also be inserted into the guide groove 620 and slide along the guide groove 620. As the guide groove 620 goes further in and further away from the first slot, the guide plate 422 will gradually move outward, allowing the positioning rod 421 to disengage from the positioning plate 41. At this time, the positioning plate 41 can also move into the second slot.

[0051] In one embodiment, one end of the protective sleeve 6 is slidably connected to the fixed frame 7 via the movable plate 60, one end of the buffer assembly 8 is connected to the movable plate 60, a baffle 61 is provided at the end of the protective sleeve 6 away from the movable plate 60, the baffle 61 is slidably connected to the protective sleeve 6, and a driving assembly 62 is provided inside the protective sleeve 6, the driving assembly 62 is used to drive the baffle 61 to slide.

[0052] The drive assembly 62 is activated by the positioning plate 41. After the positioning plate 41 is inserted into the second slot, the drive assembly 62 will be activated, thereby driving the baffle 61 to move inward and clamp the fixing card 4.

[0053] In one embodiment, the drive assembly 62 includes a push rod 621 located in the second slot. One end of the push rod 621 is provided with a movable frame 622, which is movably connected to the protective sleeve 6 via a first guide rod 623. The end of the movable frame 622 away from the push rod 621 is provided with a first wedge 624, and a second wedge 625 is movably provided on the first wedge 624. The second wedge 625 is movably connected to the protective sleeve 6 via a second guide rod 626. The surface where the two wedges are connected is an inclined surface, so that when the first wedge 624 slides along the surface of the second wedge 625, the second wedge 625 can be pushed to slide. The second wedge 625 is provided with a drive rod 627 connected to the baffle 61, and a return spring 628 is provided on one side of the drive rod 627.

[0054] After the positioning plate 41 is inserted into the second slot, the positioning plate 41 pushes the push rod 621, the push rod 621 pulls the movable frame 622, the first wedge 624 on the movable frame 622 slides along the surface of the second wedge 625, thereby pushing the second wedge 625, the second wedge 625 drives the baffle 61 through the drive rod 627, so that the baffle 61 limits and fixes the fixing card 4 and protects it.

[0055] In one embodiment, the buffer assembly 8 includes two pull rods 81 slidably connected to the movable plate 60. A buffer rod 82 is rotatably provided at one end of the pull rod 81. A fixed rotating shaft is inserted into the positioning plate 41. The end of the buffer rod 82 away from the pull rod 81 is sleeved on the fixed rotating shaft. A limiting rod 9 is connected to the fixed rotating shaft. A protrusion 83 is provided on the pull rod 81. A second limiting spring 84 is provided between the two protrusions 83. The elastic force of the second limiting spring 84 is the largest among all the springs.

[0056] A slide bar 73 is provided inside the frame 2, and a connecting rod 71 is provided on the fixed frame 7. A movable slider 72 is provided at the end of the connecting rod 71 away from the fixed frame 7 and is sleeved on the slide bar 73. Compression springs 74 are provided on both sides of the movable slider 72 and are sleeved on the slide bar 73. A damper 75 is also provided inside the fixed frame 7, and the movable plate 60 is connected to the movable end of the damper 75.

[0057] One end of the limiting rod 9 is rotatably provided with a first fixing block 91, which is connected to a fixed rotating shaft; the other end of the limiting rod 9 is rotatably provided with a second fixing block 92, which is fixed to the frame 2.

[0058] Only one of the two sets of buffer components 8 is activated at a time, and it will compress the damper 75 on the other side. At the same time, the two limit rods 9 will also deflect synchronously, thereby pushing the entire fixed frame 7 to move forward or backward. Specifically, if the fixed card 4 moves to the left or forward (these two happen simultaneously), the fixed card 4 will approach the protective sleeve 6 on the left side, which will cause the two buffer rods 82 on the left side to deflect, and their ends that are far apart will open up and down to the sides. At the same time, it will stretch the second limit spring 84 in the middle. As for the buffer component 8 on the right side, since the two buffer rods 82 on the right side cannot deflect inward, it will directly pull the entire buffer component 8 on the right side through the fixed card 4. The buffer component 8 on the right side pulls the movable plate 60 to compress the damper 75. At the same time, it will also drive the limit rod 9 to deflect, compressing or stretching the compression spring 74. The elasticity of the damper 75, the compression spring 74, and the second limit spring 84 is used to reduce the shaking of the fixed card 4.

[0059] In the event of an accident, such as a significant instantaneous change in speed, taking leftward movement as an example, the fixed clip 4 will move towards the protective sleeve 6 on the left, activating the buffer assembly 8 and the limiting rod 9. Due to the large impact force, even after the two buffer rods 82 are parallel to each other, meaning the second limiting spring 84 is stretched to its maximum, the impact force will still push the fixed clip 4 inward. The fixed clip 4 continues to move. At this point, the buffer rod 82 flips to the other side, directly changing the deflection direction of the buffer rod 82. At this time, the elasticity of the second limiting spring 84 is no longer a resistance to the impact force, but will drive the two buffer rods 82 to rotate to the other side, allowing the fixed clip 4 to be directly inserted into the protective sleeve 6 for protection. In this way, even if the external impact force is removed, the fixed clip 4 will still be firmly located inside the protective sleeve 6 under the elasticity of the second limiting spring 84 and send a signal.

[0060] At this point, a lifting component can be installed inside the protective sleeve 6. After confirming safety, the fixing card 4 can be pushed out of the protective sleeve 6 to maintain its original state.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
