[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to 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 position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] Reference Figure 1-Figure 8 As shown, a transportation management system based on Beidou positioning is mainly composed of a steel structure transportation tracking system terminal based on Beidou positioning, a mobile phone app terminal, a Beidou chip 5 and a fixed card 4. The Beidou chip 5 is bound to the steel structure component or its transportation 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 phone app terminal, and the transportation information can be synchronized to the steel structure transportation tracking system terminal in real time, thereby forming an overall steel structure tracking system based on Beidou positioning.

[0036] The steel structure transportation tracking system terminal based on Beidou positioning mainly refers to the PC / web terminal. Its main function is to facilitate the background management to check the transportation status of steel structure components in real time. It integrates functional modules including component list import and export, big data stand, single component details, special status warning, etc.

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

[0038] The Beidou positioning chip has built-in Beidou satellite positioning technology and combined navigation technology, which can achieve 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] The frame 2 is fixed to the steel member 1 by means of the snap fasteners 3, and may also be fixed by means of other mounting components such as bolts;

[0041] The fixed card 4 is arranged in the frame 2, and the Beidou chip 5 is installed in the fixed card 4. The transport vehicle will have a certain degree of shaking during the movement, and the fixed card 4 can move forward, backward, left and right in the frame 2;

[0042] The fixing frame 7 is arranged in the frame 2. The fixing frame 7 can move forward and backward relative to the frame 2, and the fixing card 4 can move left and right relative to the fixing frame 7. When the fixing frame 7 moves forward and backward, the fixing card 4 is also forced to move left and right. When the fixing frame 7 moves forward, the fixing card 4 moves leftward.

[0043] Two protective covers 6 are respectively arranged on both sides of the fixing card 4 and are slidably connected to the fixing frame 7 to protect the fixing card 4. When a violent movement such as a collision occurs, the speed will change greatly. At this time, the fixing card 4 will shake greatly, so that the fixing card 4 can be directly inserted into the protective cover 6 to protect the Beidou chip 5.

[0044] At the beginning, the Beidou chip 5 is not inserted into the protective cover 6 and is in a relatively exposed state. When the Beidou chip 5 is working, it can produce a certain heat dissipation effect. After the Beidou chip 5 produces a large impact, it can be inserted into the protective cover 6 for protection.

[0045] The buffer component 8 is arranged between the fixing card 4 and the protective cover 6, and is used to buffer the fixing card 4 and reduce the shaking of the Beidou chip 5;

[0046] The limiting rod 9 is rotatably disposed on the buffer assembly 8 and is used to push the buffer assembly 8 so that the fixing bracket 7 can drive the fixing card 4 to move left and right when moving forward and backward.

[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 matching with the fixing card 4 is provided in the protective cover 6, a second slot located on one side of the first slot is provided in the protective cover 6, and the second slot matches with the positioning plate 41;

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

[0049] In one embodiment, the positioning assembly 42 includes a positioning rod 421 inserted on the fixing card 4, the positioning rod 421 is inserted in 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 in the fixing card 4, a first limit spring 424 sleeved on the positioning rod 421 is provided on one side of the pressure plate 423, and a guide groove 620 matched with the guide plate 422 is further provided in the protective cover 6, and 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 cover 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 moves further inward and further away from the first slot, the guide plate 422 will gradually move outward, allowing the positioning rod 421 to separate 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 cover 6 is slidably connected to the fixing frame 7 through a movable plate 60, one end of the buffer assembly 8 is connected to the movable plate 60, a baffle 61 is provided at one end of the protective cover 6 away from the movable plate 60, the baffle 61 is slidably connected to the protective cover 6, and a driving assembly 62 is provided in the protective cover 6, and the driving assembly 62 is used to drive the baffle 61 to slide;

[0052] The driving assembly 62 is started by the positioning plate 41 . After the positioning plate 41 is inserted into the second slot, the driving assembly 62 is started, thereby driving the baffle 61 to move inwards through the driving assembly 62 to clamp the fixed card 4 .

[0053] In one embodiment, the driving assembly 62 includes a push rod 621 located in the second slot, a movable frame 622 is provided at one end of the push rod 621, and the movable frame 622 is movably connected to the protective cover 6 through a first guide rod 623, and a first wedge block 624 is provided at one end of the movable frame 622 away from the push rod 621, and a second wedge block 625 is movably provided on the first wedge block 624, and the second wedge block 625 is movably connected to the protective cover 6 through a second guide rod 626, and the surface connecting the two wedge blocks is an inclined surface, so that when the first wedge block 624 slides along the surface of the second wedge block 625, the second wedge block 625 can be pushed to slide, and a driving rod 627 connected to the baffle 61 is provided on the second wedge block 625, and a return spring 628 is provided on one side of the driving 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, and the first wedge block 624 on the movable frame 622 slides along the surface of the second wedge block 625, thereby pushing the second wedge block 625, and the second wedge block 625 drives the baffle 61 through the driving rod 627, so that the baffle 61 limits and fixes the fixed 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, one end of the pull rod 81 is rotatably provided with a buffer rod 82, a fixed shaft is inserted on the positioning plate 41, one end of the buffer rod 82 away from the pull rod 81 is sleeved on the fixed shaft, the limit rod 9 is connected to the fixed shaft, the pull rod 81 is provided with a protrusion 83, and a second limit spring 84 is provided between the two protrusions 83, wherein the elastic force of the second limit spring 84 is the largest among all;

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

[0057] A first fixing block 91 is rotatably provided at one end of the limiting rod 9, and the first fixing block 91 is connected to the fixed rotating shaft. A second fixing block 92 is rotatably provided at the other end of the limiting rod 9, and the second fixing block 92 is fixed on the frame 2.

[0058] Only one of the two groups of buffer components 8 will be started at a time, and the damper 75 on the other side will be compressed. At the same time, the two limit rods 9 will also be synchronously deflected, thereby pushing the entire fixing frame 7 to move forward or backward. Specifically, if the fixing card 4 moves to the left or forward (these two things happen at the same time), the fixing card 4 is close to the protective cover 6 on the left, which will cause the two buffer rods 82 on the left to deflect, and the ends away from each other will open to the upper and lower sides, and at the same time, the second limit spring 84 in the middle will be stretched. As for the right side buffer component 8, since the two buffer rods 82 on the right side cannot deflect inward, the entire right side buffer component 8 will be directly pulled through the fixing card 4. The right side buffer component 8 pulls the movable plate 60 to compress the damper 75. At the same time, it will also drive the limit rod 9 to deflect, compress or stretch the compression spring 74, and use the damper 75 and the elastic force of the compression spring 74 and the second limit spring 84 to reduce the shaking of the fixing card 4.

[0059] If an unexpected event occurs, that is, the instantaneous speed changes greatly, taking the movement to the left as an example, the fixed card 4 will move toward the protective cover 6 on the left, and start the buffer assembly 8 and the limit rod 9. Due to the large impact force, when the two buffer rods 82 are parallel to each other, that is, after the second limit spring 84 is stretched to the maximum, the impact force will push the fixed card 4 inward, and the fixed card 4 continues to move. At this time, the buffer rod 82 flips to the other side, directly changing the deflection direction of the buffer rod 82. At this time, the elastic force of the second limit 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, so that the fixed card 4 can be directly inserted into the protective cover 6 for protection. In this way, even if the external impact force is removed, the fixed card 4 will still be firmly located in the protective cover 6 under the elastic force of the second limit spring 84 and send a signal;

[0060] At this time, a lifting component can be arranged in the protective cover 6, that is, after ensuring safety, the fixing card 4 can be pushed away from the protective cover 6 to maintain the 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
