Description

Technical Field

[0001] This utility model relates to the technical field of explosion-proof base stations, and in particular to an explosion-proof base station and a three-dimensional visualization system. Background Technology

[0002] UWB positioning technology is a wireless communication technology based on nanosecond-level pulse signals. It achieves high-precision positioning by measuring the signal propagation time difference or arrival time difference. In use, a UWB mobile tag is worn on the object being located and periodically sends UWB signals. The UWB explosion-proof base station receives the UWB signals from the mobile tag and then communicates with a host computer via Ethernet or wirelessly. The host computer combines the coordinates of the UWB explosion-proof base station to calculate the three-dimensional coordinates of the UWB mobile tag. Then, the three-dimensional visualization software platform receives the coordinate data calculated by the host computer and renders the three-dimensional position of the object being located in the spatial model in real time.

[0003] UWB explosion-proof base stations need to be installed in a high position to avoid obstruction and maximize their visible coverage. At the same time, it is forbidden to install the base station above obstructions such as ceilings, low-voltage cable trays, fire pipes, air conditioning pipes, and indoor green plants. The positioning base station should be installed in the correct posture, facing down, and should not be installed vertically or at an angle.

[0004] When using existing UWB explosion-proof base stations, the equipment is usually fixed directly to the wall with bolts. In this fixing process, the installer needs to first install the base plate, then hold the UWB explosion-proof base station and install the bolts to fix the UWB explosion-proof base station to the base plate. This makes the installation, measurement and calibration process take a long time and the installation efficiency is not high. Utility Model Content

[0056] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0057] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0058] Example 1, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 14 This is the first embodiment of the present invention, which provides an explosion-proof base station. The device includes a base station body 500, a mounting base plate 505 disposed on one side of the base station body 500, a cavity provided inside the mounting base plate 505, and a guide surface 507 provided on the mounting base plate 505; and a base station fixing seat 508, with an expansion guide port 509 provided on the front side of the base station fixing seat 508.

[0059] The mounting base 505 has a guide strip 506 at its bottom and a slot 511 on its surface. The base station mounting bracket 508 has a mounting bracket slide groove 510 at its bottom and a clip 512 connected to it. A cable connector 513 is fixedly connected to one side of the base station body 500. The cable connector 513 is either horizontal or inclined toward the mounting base 505.

[0060] It also includes a UWB signal receiver 601 and a circuit assembly 600; the circuit assembly 600 includes a power module 602, a signal processing module 603, a communication module 604, and a control module 605; the power module 602 and the control module 605 are bidirectionally connected, the control module 605 is connected to the signal processing module 603, the signal processing module 603 is connected to the UWB signal receiver 601, and is used to parse the received signal data and output the processing results; the communication module 604 is connected between the signal processing module 603 and an external device, and is used to send the processing results to the external device; a power interface 606 is provided on one side of the power module 602, and a communication interface 607 is provided on one side of the communication module 604; both the power interface 606 and the communication interface 607 are pin structures and are both located inside the cable connector 513.

[0061] During use, multiple UWB explosion-proof base stations are installed on the ceiling or wall of the monitoring area during installation. They are connected to the industrial Ethernet via wired connection. Each base station is configured with a unique IP address through a configuration tool. It supports a dual-channel data reporting mechanism between the main server and the backup server. As required by the technicians, the base station mounting bracket 508 is fixed in a specific position with expansion screws, and the mounting base plate 505 is pushed toward the base station mounting bracket 508.

[0062] During the initial insertion, the triangular structure and the inclined surface on the expansion guide port 509 guide each other, and with the guiding effect of the inclined guide surface 507, the expansion guide port 509 of the base station mounting base 508 can be inserted into the gap between the U-shaped structures, so that the guide strip 506 on the guide mounting base plate 505 can be roughly aligned with the mounting base slide groove 510.

[0063] When pushed, the opening of the expansion guide port 509 is larger on the side facing outward, and smaller on the side facing the fixed seat slide groove 510 and directly connected to the fixed seat slide groove 510 to form a complete guide groove; so that when pushed, the guide bar 506 can be guided to slide into the fixed seat slide groove 510 after contacting both sides of the expansion guide port 509.

[0064] During the insertion process, the card 512 set on the base station mounting base 508 is pressed down. After the insertion is completed, the card 512 rebounds due to its own elasticity and is locked into the slot 511. There are two cards 512 and two slots 511, which realizes reliable fixation of the base station body 500.

[0065] At this point, the base station body 500 and the base station mounting base 508 are stably connected, forming a reliable fixation, thereby enabling rapid installation;

[0066] Then, the cable is connected. The cable needs to be connected to the base station body 500 using a compliant wire harness with an explosion-proof flexible tube. When the cable connector 513 is horizontal, it is easier to connect. When the cable connector 513 is tilted towards the mounting base plate 505, it needs to be connected before installation. However, after connection, due to the tilt angle, when water droplets fall on the cable connector 513, they will not stay at the interface for too long, reducing the possibility of water ingress.

[0067] Then, a marker for total station positioning is installed at the center of the top cover 502 of the base station body 500 using a temporary positioning frame. The total station is then used to measure the distance to the marker. After measuring the distance, the relative position of the base station body 500 can be obtained. This relative position, combined with the position of the total station itself, can give the approximate position of the base station body 500 in space.

[0068] In use, the power module 602 is connected to an external power supply through the power interface 606 located on one side. The power interface 606 is a pin-type structure and is integrated inside the cable connector 513 to ensure good sealing and explosion-proof performance in hazardous environments. The power module 602 establishes a bidirectional connection with the control module 605, providing operating voltage to the control module 605 while receiving start / stop, fault detection, or low-power switching commands from the control module to achieve system-level power management.

[0069] The control module 605, as the core control unit of the base station, is further connected to the signal processing module 603 to coordinate signal acquisition, timestamp recording, and processing logic. The signal processing module 603 is connected to the UWB signal receiver 601 via an internal data bus, receives UWB pulse signals from the positioning tag 51, and performs digitization, filtering, identification, and Time of Arrival (TOA) marking on the signals to ultimately form structured positioning signal data.

[0070] The processed data is output from the signal processing module 603 to the communication module 604. The communication module 604 has a communication interface 607 on one side, which also adopts a pin structure and is integrated inside the cable connector 513. The communication module 604 establishes a data communication connection with external Ethernet or Wi-Fi devices through the communication interface 607, encapsulates the positioning signal data into network data packets and transmits them to the host computer.

[0071] In this embodiment, the host computer receives timestamps and signal strength information from multiple explosion-proof base stations, and calculates the three-dimensional spatial position of the positioning tag using the TDOA (Time Difference of Arrival) or TOA (Time of Arrival) algorithm in combination with the preset spatial coordinates of each base station, thereby realizing real-time data driving and output of the overall positioning function.

[0072] Example 2, refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 16 This is the second embodiment of the present invention, providing an explosion-proof base station. This embodiment differs from the first embodiment in that: a protective frame 100 with a slidingly connected crossbar 200; a positioning block 300 with a plug-in block 301 on one side; and a positioning rod 400 inserted into the plug-in block 301. The positioning rod 400 includes a thin rod segment 400a and a snap-fit ​​segment 400b, where the thin rod segment 400a is a rigid rod. A scale groove 401 is provided on section 400a; a snap-fit ​​groove 400c is provided on snap-fit ​​section 400b, and a reflector 700 is snapped into the inside of the snap-fit ​​groove 400c; a reference groove 501 is provided at the top edge of the base station body 500; the positioning rod 400 is composed of a left rod 402 and a right rod 403, a groove 404 is provided on the side of the left rod 402 opposite to the right rod 403, and a protrusion 405 is provided at the corresponding position of the right rod 403 opposite to the left rod 402;

[0073] The crossbar 200 has a first groove 201 at both ends, and the protective frame 100 has a second groove 101 at both ends that is in the same direction as the first groove 201. A sliding groove 102 is provided on one side of the protective frame 100, and rectangular guide portions 200a are provided on both sides of the crossbar 200. The guide portions 200a and the sliding groove 102 are adapted to each other. There are two protective frames 100 and two crossbars 200. The two protective frames 100 are fixedly connected to the symmetrical sides of the top cover 502, and the two crossbars 200 are slidably connected between the protective frames 100. The base station body 500 includes a top cover 502 and a bottom shell 503. The bottom shell 503 has an installation cavity 504 inside, which is used to install the circuit assembly 600.

[0074] Compared to Embodiment 1, further, a positioning block 300 is selected first, and the positioning rod 400 is inserted into the plug block 301. Each horizontal rod 200 has a rectangular guide portion 200a on both sides. The guide portion 200a can slide along the sliding groove 102 opened on one side of the protective frame 100 to achieve lateral position adjustment. By adjusting the position of the horizontal rod 200 and the positioning block 300, the bottom end of the positioning rod 400 can accurately abut against the calibrated antenna position. A scale groove 401 is provided on the thin rod section 400a. A reference groove 501 opened on the edge of the top cover 502 of the base station body 500 provides a reference. The interior of the top cover 502 is a hollow structure. The UWB signal receiver 6... 01 The top is located inside the top cover 502. The reference slot 501 is a factory-preset mark position. Its height value is the height value of the UWB signal receiver 601 to be installed in this device. After aligning with the calibrated antenna position, the height offset between the scale slot 401 and the reference slot 501 can be quickly read, so that the height offset of the reflector 700 can be quickly calibrated. After positioning, rotate the positioning rod 400 so that the reflector 700 faces the total station. Start the total station to measure, thereby realizing the rapid three-dimensional coordinate acquisition of the base station antenna position. After the acquisition is completed, correct the height value, and the accurate position of the UWB signal receiver 601 can be obtained.

[0075] After the measurement is completed, the reflector 700 is pulled out from the snap-fit ​​section 400b, the positioning rod 400 is disassembled into the left rod 402 and the right rod 403, the crossbar 200 is pushed to the initial position and reset between it and the protective frame 100; the left rod 402 and the right rod 403 are respectively inserted into the second groove 101 provided on both sides of the protective frame 100, and further inserted into the first groove 201 on the crossbar 200 to achieve fixation between them and the crossbar 200.

[0076] The positioning rod 400 consists of a left rod 402 and a right rod 403. The left rod 402 has a groove 404 on one side, and the right rod 403 has a protrusion 405 on one side. The two are inserted together to form an integrated rod structure. The positioning rod 400 body includes two sections: one end is a thin rod section 400a, made of a hard material (such as plastic), which is used to ensure structural stability and measurement accuracy; the other end is a snap-fit ​​section 400b, made of rubber, which allows the snap-fit ​​groove 400c to insert and fix the reflector 700 in the snap-fit ​​groove 400c, which not only ensures the fixation performance, but also facilitates quick assembly and disassembly.

[0077] The remaining structure is the same as that in Example 1.

[0078] Example 3, referring to Figure 15The explosion-proof base station, as described in any one of claims 1 to 9, further includes a positioning tag 51, a host computer 52, a three-dimensional visualization software platform 53, and a reflector 700; the explosion-proof base station is electrically connected to the host computer 52, the host computer 52 is connected to the three-dimensional visualization software platform 53, and the positioning tag 51 is wirelessly connected to the UWB explosion-proof base station 50; the reflector 700 is disposed on the explosion-proof base station and cooperates with its positioning structure to assist in three-dimensional spatial position calibration.

[0079] Compared to Example 2, the height measured by the positioning rod 400 is further used as a correction parameter. The correction parameter is input into the UWB explosion-proof base station 50 and then combined with the coordinates of the reflector 700 in three-dimensional space measured by the total station. The height of the Z-axis is added to the correction parameter to obtain the true position of the UWB explosion-proof base station 50, so that the correct coordinates of the UWB explosion-proof base station 50 can be used in subsequent measurements.

[0080] During positioning, the positioning tag 51 periodically sends UWB signals. Multiple UWB explosion-proof base stations 50 receive the UWB signals and extract the corresponding arrival time information. The arrival time information and the coordinates of each UWB explosion-proof base station 50 are sent to the host computer 52 through the interface. The host computer 52 calculates the coordinate position of the positioning tag 51 in three-dimensional space based on the arrival time information and the coordinates of the UWB explosion-proof base stations 50, and transmits the coordinate position to the three-dimensional visualization software platform 53 for real-time three-dimensional rendering. The visualization rendering is completed within the established spatial model, realizing accurate visual positioning of the object carried by the tag (such as workers, equipment, etc.) within the monitoring area.

[0081] The remaining structure is the same as that in Example 2.
