[0021] like Figures 1 to 5As shown, the utility model provides a portable UWB data log recording device, which mainly includes a battery and power management module, a processor module, a display module, a button module, a switch module, a UWB receiving module (including a DWM1000 module and a DWM3000 module), an indicator light module, a storage module and a USB to serial port module (see Figure 1 ),in:

[0022] The battery and power module are responsible for the power supply of the entire device. When the device is connected to a power adapter, the power supply is used to supply power and charge the battery at the same time. When the device is not connected to a power adapter, the battery is used to supply power to the entire device.

[0023] The processor module is composed of the STM32F429IGT6 chip and supports a maximum operating frequency of 180MHz, which is used to realize data reading, processing, storage and forwarding functions;

[0024] The display module consists of a 3.2-inch LCD screen, to which the processor chip is connected via the LTDC interface, and is used to display received data and configure the device;

[0025] The key module consists of multiple touch switches, and the processor chip is connected to it through IO pins to configure some functions of the device and control the operation of the device;

[0026] The switch module consists of multiple sliding switches, and the processor chip is connected to it through IO pins to configure the device's transparent transmission function and logging function;

[0027] The UWB receiving module consists of the DWM1000 module and the DWM3000 module. The processor chip is connected to them through two different SPI interfaces to receive UWB data in the air.

[0028] The indicator light module consists of multiple LED lights of different colors. The processor chip is connected to it through the IO pin to display the current working status of the device.

[0029] The storage module is composed of an SD card, and the processor chip is connected to it through the SDIO interface to realize the functions of saving and reading log data files and reading configuration files;

[0030] The USB to serial port module is implemented by CH340, and the processor chip is connected to it through the USART interface to realize the conversion of serial port data to USB data.

[0031] The working process of this device is shown in Figure 2UWB data acquisition is primarily accomplished through two UWB receiver modules, the DWM1000 and DWM3000, supporting channels 1, 2, 3, 4, 5, 7, and 9. Upon powering up, the device first reads the corresponding configuration file from the SD card and sets the default data acquisition channel based on the channel specified in the configuration file. Users can also adjust the desired acquisition channel using buttons. After selecting a channel, users can modify the configuration file to configure frame filtering conditions based on their usage, such as the frame format and length of UWB data frames, as well as the destination address and PAN. Frame filtering can also be disabled to directly capture all UWB data frames over the air. After setting the frame filtering conditions, users can select the acquisition time. The acquisition time is optional and can be skipped, resulting in continuous acquisition. After configuration is complete, press the Start Acquisition button. The device will collect valid data packets over the air according to the configured conditions and display the results on the screen. If logging is enabled, the data will be timestamped and the results will be saved to a log file. If the transparent transmission switch is turned on, the collected data will be output through the serial port to USB module, and the host computer can be connected to view the transparent data in real time.

[0032] The application scenarios of this device can be seen in Figure 3 、 Figure 4 、 Figure 5 In a one-to-one scenario of UWB products, the device can collect the content of communication between devices, and save and analyze whether the communication is carried out as required.

[0033] In many-to-one and many-to-many scenarios, the device collects data from communications between devices and outputs the results via the serial port to a host computer, which can analyze and compile statistics, calculate system performance, and identify and address gaps. In some special working conditions, the log save function can also be used to record and save data for later centralized analysis.

[0034] Existing technologies offer only simple data forwarding. This device not only supports low-latency transparent data transmission but also features efficient logging. Its built-in battery greatly enhances its operational flexibility, enabling it to operate for extended periods in complex working conditions. The device supports both direct configuration via configuration files and keystrokes, adapting to diverse work scenarios. The included display allows for real-time viewing of both currently collected data and data already stored in the log.
