Description

Technical Field

[0001] This utility model relates to the field of anti-collision positioning equipment technology, specifically an anti-collision positioning device based on UWB ranging. Background Technology

[0002] Collision avoidance positioning devices are intelligent safety equipment that integrates positioning, ranging, and early warning functions. They are mainly installed in mobile devices (such as industrial robots, logistics AGVs, and intelligent vehicles) or specific scenarios (such as warehouses, factories, and mines). By acquiring the position and distance information of target objects in real time and combining it with preset safety thresholds, it triggers actions such as audible and visual alarms, deceleration, or braking when a potential collision risk is detected, thereby avoiding collision accidents. UWB (Ultra-Wideband) technology is based on extremely short pulse signal transmission. UWB's high precision, anti-interference ability, and real-time performance make it an ideal choice for collision avoidance positioning devices, especially suitable for industrial scenarios with high automation and strict safety requirements.

[0003] Existing collision avoidance positioning devices based on UWB ranging involve UWB tags within the device exchanging extremely short pulse signals with base stations (or tags mounted on other devices). The time-of-flight (ToF) or time-of-arrival (TDoA) algorithms are used to calculate the signal transmission time, which is then converted to a precise distance between the two devices (with centimeter-level error) based on the speed of light. Simultaneously, multi-base station collaborative positioning is used to calculate the target's three-dimensional coordinates. The system monitors distance and position data in real time. When a target is detected entering a preset safety threshold range, a warning signal is immediately triggered, prompting the device to perform deceleration and shutdown operations. Through high-precision ranging and real-time data interaction, accurate prediction and proactive avoidance of collision risks are achieved. However, during long-term use and internal maintenance, screwdrivers and other tools are required to loosen the outer casing one by one to remove the internal electronic components for inspection and replacement.

[0004] Existing collision avoidance positioning devices based on UWB ranging require disassembling the outer casing for internal maintenance, which necessitates removing each screw individually. This is especially problematic when the casing is secured with multiple screws, resulting in lengthy maintenance times, the need for specialized tools, and a high level of operator skill. Non-professionals may damage internal components due to improper operation, affecting the stability of the UWB signal. Therefore, we propose a collision avoidance positioning device based on UWB ranging. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a collision avoidance and positioning device based on UWB ranging, which realizes the rapid disassembly and assembly of the device shell, greatly shortens the maintenance time, improves the equipment operation and maintenance efficiency, facilitates rapid emergency handling, and provides strong support for the efficient and stable operation of the UWB ranging collision avoidance and positioning device, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision avoidance positioning device based on UWB ranging, including a base plate, a UWB chip on the upper front side of the base plate, a UWB antenna on the upper rear side of the base plate, a rectangular groove inside the base plate, a shell inside the rectangular groove, and a quick disassembly and assembly mechanism.

[0007] The quick-assembly and disassembly mechanism includes a rectangular frame, a pressing block, a fixing block, and a pressing block. The rectangular frame is located inside the rectangular slot, and the fixing blocks are located on the left and right inner walls of the rectangular frame. The pressing blocks are located on the left and right sides of the outer shell. The upper surface of the fixing block and the lower surface of the pressing block are both inclined. The fixing block is installed in conjunction with the vertically adjacent pressing block. The pressing block is located on the front side of the rectangular frame, and the avoidance groove corresponding to the pressing block is located on the front side of the base plate. This mechanism enables quick assembly and disassembly of the device outer shell, significantly shortens maintenance time, improves equipment operation and maintenance efficiency, facilitates rapid emergency handling, and provides strong support for the efficient and stable operation of the UWB ranging and anti-collision positioning device.

[0008] Furthermore, a microcontroller is provided on the front side of the housing, and the input terminal of the microcontroller is electrically connected to an external power source. A data transmitter is provided in the upper middle part of the base plate, and the input terminal of the data transmitter is electrically connected to the output terminal of the microcontroller, providing electrical connections for various electrical appliances.

[0009] Furthermore, the quick assembly / disassembly mechanism also includes dovetail sliders and dovetail grooves. Dovetail grooves are respectively provided on the inner walls of the left and right sides of the rectangular groove, and dovetail sliders are respectively provided on the left and right sides of the rectangular frame. The dovetail sliders are all slidably connected to the inside of the dovetail groove on the same side to prevent shaking inside the rectangular groove.

[0010] Furthermore, the quick assembly / disassembly mechanism also includes telescopic rods and springs. The rear sidewall of the rectangular groove is provided with telescopic rods, and the front end of the telescopic rods is fixedly connected to the rear side of the rectangular frame. The springs are movably sleeved on the outside of the telescopic rods and are located between the rear sidewall of the rectangular groove and the rear side of the rectangular frame, so as to realize the automatic rebound sliding of the rectangular frame.

[0011] Furthermore, the quick assembly / disassembly mechanism also includes a fixing pin, a support plate is provided on the front side of the base plate, a fixing pin is slidably connected to the middle of the support plate, and a positioning hole corresponding to the fixing pin is opened on the left side of the pressing block to restrict the sliding of the pressing plate.

[0012] Furthermore, an alarm is installed on the outside of the base plate, and the input terminal of the alarm is electrically connected to an external power source to facilitate alerting staff.

[0013] Furthermore, connecting plates are fixedly connected to the left and right sides of the base plate, and fixing holes are opened in the middle of the connecting plates to facilitate the fixing of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This collision avoidance positioning device based on UWB ranging has the following advantages:

[0015] By pressing the pressing block, the rectangular frame slides inside the rectangular groove, causing the fixing block to move backward and avoid the squeezing block. The outer casing can then be gently lifted upward to remove it. After maintenance, align the outer casing with the rectangular groove and insert it downward, pressing gently. As the pressure is transmitted, the fixing block compresses the spring behind the rectangular frame, allowing the outer casing to sink. When the squeezing block passes the fixing block, the spring instantly releases its elastic potential energy, pushing the rectangular frame forward to reset, causing the lower surface of the fixing block to fit against the upper surface of the squeezing block, completing automatic locking. This allows for quick assembly and disassembly of the anti-collision positioning device without the need for other auxiliary tools, significantly improving maintenance efficiency, effectively reducing equipment downtime, and shortening the time internal components are exposed, thus reducing indirect impacts on the reliability of the UWB signal link.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This embodiment provides a technical solution: a collision avoidance positioning device based on UWB ranging, including a base plate 1. A UWB chip 2 (a chip used in existing UWB ranging collision avoidance positioning devices, responsible for generating and modulating digital signals (such as nanosecond-level pulse sequences), but digital signals cannot directly propagate through space and need to be converted and transmitted through a UWB antenna 3) is located on the upper rear side of the base plate 1. A UWB antenna 3 (realizing spatial signal propagation; its performance (such as bandwidth and directivity) directly affects ranging accuracy and communication distance) is also provided on the base plate 1. The base plate 1 has a rectangular slot 5 inside, and a housing 4 is located inside the rectangular slot 5. It also includes a quick-release mechanism 6. A microcontroller 7 is located on the front side of the housing 4, and the input of the microcontroller 7 is electrically connected to an external power source. A data transmitter 8 is located in the middle of the upper part of the base plate 1, and the input of the data transmitter 8 is electrically connected to the output of the microcontroller 7. An alarm 9 is located on the outside of the base plate 1, and the input of the alarm 9 is electrically connected to an external power source. Connecting plates 10 are fixedly connected to the left and right sides of the base plate 1, and each connecting plate 10 has a fixed... In factory manufacturing, when anti-collision positioning devices are needed to ensure the safety of personnel and equipment, the UWB positioning base station is first installed in a fixed location such as the factory ceiling, wall, or shelf. (It emits UWB pulse signals as a reference for time synchronization and ranging, receives signals emitted by UWB tags worn by factory vehicles and personnel, calculates the time of flight (ToF) or time difference of arrival (TDoA) between the tag and the base station, and determines the real-time position of the tag.) The base plate 1 is then installed on the roof of the factory vehicle. The UWB chip 2 on the upper part of the base plate 1 then connects to the base plate via UWB... Antenna 3 will send pulse signals to the UWB positioning base station in real time. After receiving the signals, the UWB positioning base station will calculate and organize all the signals. The UWB positioning base station will then transmit the calculated data to the data transmitter 8 with the support of the wireless network. The data transmitter 8 will then transmit the data to the microcontroller 7. The microcontroller 7 will integrate the data. When the data exceeds the set value, the microcontroller 7 will control the alarm 9 to work. The speaker inside the alarm 9 will emit a warning sound, and the alarm light at the top will flash continuously, thereby reducing the impact of the factory vehicle on the visual obstruction.

[0022] Quick-release mechanism 6: It includes a rectangular frame 61, a pressing block 62, a fixing block 63, and a pressing block 64. The rectangular frame 61 is located inside the rectangular groove 5. Fixing blocks 63 are located on the left and right inner walls of the rectangular frame 61. Pressing blocks 62 are located on the left and right sides of the outer shell 4. The upper surface of the fixing block 63 and the lower surface of the pressing block 62 are both inclined surfaces (the lower surface of the pressing block 62 is inclined from top to bottom, and the upper surface of the fixing block 63 is inclined from bottom to top). The fixing block 63 is installed in conjunction with the vertically adjacent pressing block 62. A pressing block 64 is located on the front side of the rectangular frame 61, and a clearance groove corresponding to the pressing block 64 is located on the front side of the base plate 1. Quick-release mechanism... The assembly / disassembly mechanism 6 also includes dovetail sliders 65 and dovetail grooves 66. Dovetail grooves 66 are respectively provided on the inner walls of the left and right sides of the rectangular groove 5. Dovetail sliders 65 are respectively provided on the left and right sides of the rectangular frame 61. The dovetail sliders 65 are all slidably connected to the interior of the dovetail grooves 66 on the same side. The quick assembly / disassembly mechanism 6 also includes telescopic rods 67 and springs 68. Telescopic rods 67 are respectively provided on the rear side wall of the rectangular groove 5. The front ends of the telescopic ends of the telescopic rods 67 are fixedly connected to the rear side of the rectangular frame 61. Springs 68 are movably sleeved on the outside of the telescopic rods 67. The springs 68 are located between the rear side wall of the rectangular groove 5 and the rear side of the rectangular frame 61. The quick assembly / disassembly mechanism 6... It also includes a fixing pin 69. A support plate is provided on the front side of the base plate 1, and the fixing pin 69 is slidably connected to the middle of the support plate. The left side of the pressing block 64 has a positioning hole corresponding to the fixing pin 69. However, when it is necessary to inspect the inside of the anti-collision positioning device, the fixing pin 69 is pulled out from the fixing hole of the pressing block 64, and then the pressing block 64 is pressed, so that the rectangular frame 61 slides inside the rectangular groove 5 under the limit of the dovetail slide groove 66 and the dovetail slider 65, thereby causing the fixing block 63 to move backward and avoid the squeezing block 62. The outer shell 4 can be lifted upward and removed from the rectangular groove 5, exposing the core components such as the microcontroller 7 and the UWB chip 2 inside. The components facilitate quick troubleshooting by engineers. After repair, the outer casing 4 is aligned with the rectangular slot 5 and inserted. When pressed down lightly, the inclined surface of the pressing block 62 and the inclined surface of the fixing block 63 are slidably coupled. As the pressure is transmitted, the rectangular frame 61 compresses the spring 68 and the telescopic rod 67 behind it to allow the outer casing to sink. When the pressing block 62 passes the fixing block 63, the spring 68 releases its elastic potential energy instantly, pushing the rectangular frame 61 forward to reset, so that the lower surface of the fixing block 63 fits with the upper surface of the pressing block 62, completing the automatic locking. Then, the sliding fixing pin 69 is inserted into the fixing hole on the left side of the pressing block 64 to prevent the staff from accidentally touching the pressing block 64.

[0023] The working principle of the anti-collision positioning device based on UWB ranging provided by this utility model is as follows: When an anti-collision positioning device is needed to ensure the safety of personnel and equipment during factory production, the UWB positioning base station is first installed in a fixed position such as the factory ceiling, wall, or shelf. (It emits UWB pulse signals as a reference for time synchronization and ranging, receives signals emitted by UWB tags worn by factory vehicles and personnel, calculates the time of flight (ToF) or time difference of arrival (TDoA) between the tag and the base station, and solves the real-time position of the tag.) The base plate 1 is then installed... Installed on the roof of the factory vehicle, the UWB chip 2 on the upper part of the rear floor plate 1 sends pulse signals to the UWB positioning base station in real time via the UWB antenna 3. After receiving the signals, the UWB positioning base station calculates and processes all the signals. The calculated data is then transmitted to the data transmitter 8 with the support of the wireless network. The data transmitter 8 transmits the data to the microcontroller 7. The microcontroller 7 integrates the data. When the data exceeds a set value, the microcontroller 7 will control the alarm 9 to activate. The speaker inside the alarm 9 will emit a warning sound, and the alarm light at the top will turn off. The intermittent flashing reduces collisions caused by obstructed vision on factory vehicles. However, when internal maintenance of the anti-collision positioning device is required, the fixing pin 69 is pulled out from the fixing hole of the pressing block 64, and then the pressing block 64 is pressed, causing the rectangular frame 61 to slide inside the rectangular groove 5 under the limit of the dovetail slide groove 66 and the dovetail slider 65. This causes the fixing block 63 to move backward, avoiding the squeezing block 62. The outer shell 4 can be gently lifted upward to remove it from the rectangular groove 5, exposing the internal core components such as the microcontroller 7 and the UWB chip 2, which facilitates engineers to quickly troubleshoot faults. After maintenance is completed, When the outer casing 4 is aligned with the rectangular slot 5 and inserted, and then gently pressed down, the inclined surface of the pressing block 62 and the inclined surface of the fixing block 63 are slidably coupled. As the pressure is transmitted, the rectangular frame 61 compresses the spring 68 and the telescopic rod 67 behind it, allowing the outer casing to sink. When the pressing block 62 passes the fixing block 63, the spring 68 releases its elastic potential energy instantly, pushing the rectangular frame 61 forward to reset, so that the lower surface of the fixing block 63 fits with the upper surface of the pressing block 62, completing the automatic locking. Then, the sliding fixing pin 69 is inserted into the fixing hole on the left side of the pressing block 64 to prevent the operator from accidentally touching the pressing block 64.

[0024] It is worth noting that the microcontroller 7 disclosed in the above embodiments can be AT87C5103, the data transmitter 8 can be TY511-B3, and the alarm 9 can be BBJ explosion-proof sound and light alarm. The microcontroller 7 controls the operation of the data transmitter 8 and the alarm 9 using methods commonly used in the prior art.
