Description

Technical Field

[0001] The present invention relates to the technical field of indoor positioning of the Internet of Things, and in particular to a workshop object positioning device and management system based on ultra-wideband. Background Art

[0002] Traditional discrete manufacturing workshops are often large, even extraordinarily large, spaces. They process numerous components, complex structures, and a wide variety of similar designs, leading to chaotic inventory management. Workers often struggle to find the tools or parts they need. Traditional inventory management methods often rely on manual record-keeping or low-precision positioning methods, making it difficult to accurately track item locations in real time.

[0003] Furthermore, GPS and other satellite positioning signals cannot be received indoors, making GPS positioning technology unsuitable for indoor positioning. Currently, commonly used indoor positioning technologies include infrared technology, radio frequency identification (RFID), and Bluetooth indoor positioning technology. Infrared positioning technology relies on infrared sensors to determine the target's location. It locates the target by detecting the target's reflection or radiation characteristics of infrared light and analyzing its intensity and direction. RFID positioning technology relies on radio frequency identification technology, determining the specific location of an object through wireless signal transmission between the RFID tag and the reader. Bluetooth indoor positioning technology utilizes the installation of several Bluetooth LAN access points indoors to establish a multi-user network connection mode, ensuring that the Bluetooth access point always serves as the master device. By measuring signal strength, the system can obtain the user's location information.

[0004] Infrared technology cannot penetrate walls and is not suitable for complex workshop environments. RFID is widely used for item identification and information reading, but it cannot achieve real-time, high-precision location information acquisition. It is limited by short-range positioning and identification and cannot meet the precise positioning needs of large-scale workshops. Although Bluetooth positioning technology has low costs, its positioning accuracy is limited, usually within the meter range, and it is easily interfered with by environmental signals, making it unsuitable for complex workshop environments.

[0005] In view of this, the present invention proposes a workshop object positioning device and management system based on ultra-wideband. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] This embodiment provides a workshop item and parts positioning and management system based on ultra-wideband (UWB) technology, including a positioning device and a management system, wherein:

[0041] The positioning device enables high-precision, real-time positioning, binding, unbinding, and status updates of workshop parts. It utilizes the UWB standard wireless communication protocol, offering high real-time performance and strong anti-interference capabilities, ensuring stable and reliable data transmission. The system is designed with a dynamic power management mechanism that dynamically adjusts power consumption modes based on data transmission frequency, interactive operations, and silent status, achieving overall low-energy operation and significantly extending the life of the equipment. A built-in power detection module monitors the battery charge in real time. When the charge falls below a preset threshold, a power warning is issued by the LED light switching from green to red, reminding staff to recharge promptly. In addition, the system supports an electronic fence function, allowing users to preset the activity area of ​​an item. When the locator detects that the set boundary has been exceeded, an audible and visual alarm is immediately triggered to ensure the safety of the item and prevent loss or accidental movement.

[0042] The management system includes a map positioning module, a terminal management module and an algorithm analysis module, which realizes automated management functions such as real-time positioning, binding, unbinding and status update of workshop targets.

[0043] Example 1, please refer to Figure 2-6 As shown, the present embodiment of the present invention is a workshop object positioning device based on ultra-wideband, including a UWB module, the UWB module includes a UWB positioning base station and a UWB locator, the target device 8 is the object (part) to be positioned, and the UWB locator is fixed on the target device 8, as shown in FIG. Figure 1 As shown, the UWB positioning base station is arranged in the activity area, and the UWB positioning base station exchanges positioning information with the host computer through the UWB wireless communication module 5 and the microcontroller 10; wherein:

[0044] The UWB locator is fixed on the target device 8, sends UWB signals to communicate with the UWB positioning base station and the host computer, has the functions of a display device and a button module, and supports binding and unbinding operations.

[0045] It should be noted that the UWB locator is a hardware device fixed on the target device 8, responsible for sending UWB signals and communicating with the UWB positioning base station and the host computer. It is the direct carrier for realizing object positioning and information binding, such as Figure 2As shown in the stereoscopic diagram, the UWB locator is provided with a display screen (1) on the surface for displaying the number and status information of the bound items in real time; a button 11 is designed on the side for binding or unbinding operations. In addition, the locator is also equipped with an LED red light 2 and an LED green light 3 for indicating the power status or alarm information; that is, the top of the UWB locator is provided with a display device and a key module, the display device includes a display screen 1, an LED red light 2 and an LED green light 3; the display screen 1 is preferably an OLED display screen 1, the key module includes a button 11, and the button 11 is preferably a vertical button switch; a microcontroller 10, a UWB wireless communication module 5, a buzzer module 6 and a battery compartment 12 are provided inside the UWB locator, and the battery compartment 12 is designed as a detachable structure, with a snap or sliding mechanism, so that the staff can quickly replace the battery; the battery compartment 12 is tightly matched with the locating device housing to ensure that the battery is stable and safe during the operation of the device, and to prevent the battery from loosening or accidentally falling off. It is placed in the locating device and is used to provide a stable power supply for the locating device.

[0046] The UWB locator is topped with a display device and a key module. The key module is connected to the display device via a data signal. Operating the key module displays the target's status and location information on the display device. In other words, a worker binds the UWB locator to the part number on a host computer, synchronizes the information to the UWB locator, and uses the key module to display the part number on the display device. When the target leaves the workshop, the UWB locator can be unbound from the part, and the binding or unbinding operation can be triggered using the key module. This not only enables precise target positioning but also simplifies the system's usage process and improves the intelligence level of target management.

[0047] The UWB locator also features a magnetic positioning assembly 7, which facilitates attachment and detachment of the locator to components, enhancing operational convenience and environmental adaptability in industrial scenarios. This effectively addresses issues such as blind spots in location tracking, high manual labor dependency, and the lack of multi-dimensional spatial positioning in traditional material management, providing a reliable technical solution for digital logistics upgrades in the intelligent manufacturing sector.

[0048] Specifically, the UWB locator is equipped with a microcontroller 10 (MCU) for processing location information, binding information and user interaction instructions. 2The C interface connects to the display device, sending control commands and display data to the display device. Display data includes the item number, binding status, and alarm information, ensuring real-time data transmission. The microcontroller 10 in the UWB locator connects to the key module via GPIO pins, supporting one-touch binding, unbinding, and function switching. Configuration parameters and status information are stored in the built-in flash module to ensure data is not lost during power outages, facilitating device maintenance and parameter management. GPIO interrupts are used to detect key module input events; key module events are transmitted to the display device driver via microcontroller 10 interrupts. Key module operations update the display device content, including displaying the target number or unbinding status.

[0049] To further illustrate, the positioning device has a built-in UWB wireless communication module 5, which communicates with multiple UWB positioning base stations, receives positioning signals from the UWB positioning base stations, and calculates the real-time position of the part based on the time difference of air (TDOA).

[0050] Specifically, the UWB locator periodically sends UWB signals for distance measurement and time difference calculation in the positioning management system. The UWB positioning base station receives the UWB locator signal and calculates the precise position of the UWB locator with an accuracy of up to centimeters.

[0051] To further explain, it also includes a pressure sensor 9 for collecting air pressure and altitude data; using an adaptive multimodal data fusion algorithm, the target position information and the air pressure and altitude information are dynamically combined to achieve accurate analysis of the three-dimensional spatial position of objects in a multi-floor environment, and the error of the origin locator is corrected through an adaptive calibration mechanism to improve the stability and reliability of positioning.

[0052] It should also be noted that a locator baffle 4 is also provided inside the UWB locator. The locator baffle 4 is provided on the side or near the battery compartment 12 and is used to divide and isolate the functional areas of the various modules within the UWB locator (such as the microcontroller 10, the UWB wireless communication module 5, the buzzer module 6, and the air pressure sensor 9). The locator baffle 4 is made of lightweight and durable materials, such as ABS plastic or lightweight metal materials, to provide the necessary support and protection. The baffle is designed for easy installation and removal and is firmly connected to the locator housing by snap fastening or screw fixing, ensuring the stability and safety of the internal modules, preventing accidental contact, short circuits, or loose components due to vibration, and further improving the reliability and durability of the positioning device in industrial environments.

[0053] The UWB positioning base station transmits signals through the wireless communication protocol (UWB) with the UWB locator. After receiving the UWB locator signal, the UWB positioning base station calculates the position of the UWB locator and transmits the position information to the microcontroller 10 in the UWB locator for processing. The UWB locator also transmits the target position information and binding information to the host computer management system through the wireless communication protocol. The wireless communication protocol used in the system can ensure the real-time and reliability of the data while avoiding interference and signal loss. Each UWB locator is equipped with a microcontroller (microcontroller 10) to process the received position information, control the display device to display the target number, respond to the button module operation, and transmit data to the host computer through the wireless communication module.

[0054] The UWB positioning base station is responsible for receiving the signals sent by the UWB locator and calculating the precise position of the UWB locator with an accuracy of up to centimeters. The UWB positioning base station is one of the core hardware in the UWB positioning management system. It is responsible for receiving the signals sent by the UWB locator. When the UWB locator interacts with multiple UWB positioning base stations, it can calculate the precise position of the UWB locator with an accuracy of up to centimeters. It can also ensure the consistency of the time reference of multiple UWB locators, thereby accurately calculating the time difference.

[0055] The present embodiment describes a workshop item and parts positioning device based on ultra-wideband (UWB) technology, including a UWB module, which includes a UWB positioning base station and a UWB locator, wherein the target device 8 is the item (part) to be positioned, and the UWB locator is fixed to the bottom or side of the target device 8 through a magnetic positioning component 7 to achieve convenient adsorption and disassembly.

[0056] As shown in the figure, the UWB locator is topped with a display device and a key module. The display device includes a display screen 1, a red LED light 2, and a green LED light 3, which display the target number, status, and battery information in real time. Display screen 1 is preferably an OLED display. The key module includes a button 11 located on the side of or adjacent to the display device for binding and unbinding operations. Button 11 is preferably a vertical push button switch.

[0057] The UWB locator is equipped with a microcontroller 10, a UWB wireless communication module 5, a buzzer module 6, an air pressure sensor 9, and a removable battery compartment 12 for power supply. The battery compartment 12 tightly fits into the outer shell through a snap or sliding mechanism. Located at the bottom or side of the UWB locator, it facilitates quick battery replacement and ensures stable and safe battery operation.

[0058] A red LED light 2 and a green LED light 3 are located near the display device. When the battery level drops below a preset threshold, the lights turn from green to red to indicate charging. Furthermore, a buzzer module 6 and the LED lights together form an audible and visual alarm device, which triggers an alarm when the locator exceeds the boundary of the electronic fence.

[0059] The microcontroller 10 uses I 2 The C interface connects to a display device for real-time control and display of target number, status, and alarm information. A GPIO pin connects to button 11, which responds to commands such as bind and unbind. Microcontroller 10 processes positioning information and sensor data, and uses a built-in flash module to save configuration and status information to prevent accidental data loss.

[0060] The UWB locator periodically transmits UWB signals to a UWB positioning base station via its built-in UWB wireless communication module 5. The UWB positioning base station accurately calculates the locator's position based on the time difference of attention (TDOA) of the signals, achieving centimeter-level positioning accuracy. The locator also transmits processed location information, binding status, and barometric altitude information to a host computer via the wireless communication module 5.

[0061] The air pressure sensor 9 is placed at a specific position inside the locator to collect environmental height data for dynamic calibration and error correction of three-dimensional positioning, significantly improving positioning stability and accuracy in multi-floor environments.

[0062] The overall design is compact and reasonable, and the positions are arranged in an orderly manner, which improves the usability and reliability of industrial application scenarios.

[0063] Example 2, please refer to Figure 7-8 As shown, the ultra-wideband-based workshop item positioning and management system described in this embodiment includes a map positioning module, a terminal management module and an algorithm analysis module, which realizes automated management functions such as real-time positioning, binding, unbinding and status update of workshop targets.

[0064] in:

[0065] Map positioning module, receiving target status information and target positioning information sent by UWB positioning base station;

[0066] It should be noted that the map positioning module is the data center of the entire system. It is responsible for processing the data transmitted by the UWB positioning base station and the UWB locator, and providing real-time target status information and target positioning information. It transmits the target status information and target positioning information to the terminal management module to facilitate staff operations and decision-making.

[0067] Terminal management module: The terminal management module communicates with the map positioning module, displays the results of the locator coordinates calculated by the map positioning module, and forms a visual interface. The terminal management module can store workshop data, which includes employee information data, inventory data, binding data and workshop item information data. The binding data is the binding information of all UWB locators and targets, and supports historical record query function.

[0068] Specifically, when the staff performs binding or unbinding operations through the terminal management module or button module, the management control module will update the target status information in real time and synchronize the operation results to the host computer and terminal management module.

[0069] More specifically, for target binding, the staff selects the target number on the terminal management module and binds it to the UWB locator. After binding, the target number, target position and UWB locator information will be synchronized to the host computer and the terminal management module. Similarly, for target unbinding, when the target leaves the workshop, the staff can unbind the target through the terminal management module or the button module. After unbinding, the system will update the target status information and record the unbinding time.

[0070] Through the signal interaction between the UWB positioning base station and the UWB locator, the target's position is calculated in real time, and the current position and status of the target are displayed on the terminal management module to achieve real-time positioning and monitoring. The terminal management module can also be used to query the target's historical position and status information to facilitate tracing the target's flow process.

[0071] The algorithm analysis module uses the TDOA algorithm to measure the time difference between the UWB locator sending positioning signals to multiple UWB positioning base stations to determine the target positioning information with an accuracy of up to centimeter level.

[0072] It should be noted that the location of objects in the workshop is determined based on the TDOA algorithm, achieving centimeter-level positioning accuracy to achieve precise control of objects in the workshops of discrete manufacturing enterprises. The TDOA algorithm can quickly respond to the movement of objects in the workshop and meet the requirements of dynamic object management. The TDOA algorithm can be used to locate multiple locators, improving the company's parallel management capabilities. Specifically, the TDOA algorithm is a time difference of arrival (TDOA) positioning algorithm for positioning information sent by the UWB locator, which quickly responds to the movement of targets in the workshop and meets the requirements of dynamic target management.

[0073] It's important to note that the location of objects within a workshop is determined by measuring the time difference between signals traveling from a single UWB locator to multiple UWB positioning base stations. The TDOA algorithm can achieve centimeter-level positioning accuracy, enabling precise control of objects within the workshops of discrete manufacturing enterprises. The TDOA algorithm can rapidly respond to the movement of objects within the workshop, meeting the requirements of dynamic target management. The TDOA algorithm can also be used to locate multiple UWB locators, improving enterprises' parallel management capabilities.

[0074] Further explanation: it also includes a pressure sensor 9 for collecting air pressure and altitude data; using an adaptive multimodal data fusion algorithm, the target position information and the air pressure and altitude information are dynamically combined to achieve accurate analysis of the three-dimensional spatial position of objects in a multi-floor environment, and the error of the origin locator is corrected through an adaptive calibration mechanism to improve the stability and reliability of positioning.

[0075] To further explain, the algorithm analysis module exchanges data with the UWB locator, the UWB positioning base station and the host computer through the wireless communication module 5 to ensure the real-time and consistency of information.

[0076] By integrating Internet of Things technology and high-precision UWB positioning capabilities, the shortcomings of existing discrete manufacturing enterprise target management methods (such as manual recording, RIFD positioning, and traditional barcode tracking) in terms of inaccurate workshop target positioning, low efficiency, and high manual intervention costs are overcome. Through the intelligent control of the management system and the precise positioning of the UWB positioning device, efficient, accurate, and automated technical effects are achieved.

[0077] In summary, this invention uses UWB technology and the TDOA algorithm to achieve centimeter-level high-precision positioning, ensuring target location accuracy. It supports automated target binding, unbinding, and status updates, reducing manual intervention and improving management efficiency. It monitors the target's location and status in real time, supports historical record queries, and facilitates tracing the target's movement. It can adapt to the binding management requirements of different target types, and implements real-time positioning, binding, unbinding, and status updates for workshop targets.

[0078] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
