In this embodiment, two charging methods, the wireless charging module 140 and the charging interface assembly 150, are adopted, which provides users with a variety of charging options, reduces the dependence on specific charging equipment, and avoids the inconvenience caused by a single charging method.

[0029] In one embodiment, the charging interface assembly 150 includes at least one of a TYPC interface, a USB interface, and a Lighting interface. On the one hand, the user can use a variety of different methods to charge the rechargeable battery 130. This diverse charging method not only improves the convenience of charging, but also reduces the risk of downtime of the UWB positioning tag device due to loss or damage of a specific charger. On the other hand, even if there is a problem with a charger or cable of a certain interface type, the user can still use other types of interfaces for charging to ensure the normal operation of the UWB positioning tag device.

[0030] In another embodiment, see Figure 2 The tag board 120 includes a main control module 121, which is electrically connected to a rechargeable battery 130, and the main control module 121 has a built-in positioning algorithm and identity recognition information. Specifically, the tag board 120 also includes a board body, and the main control module 121 is plugged and connected to the board body. The built-in positioning algorithm of the main control module 121 can autonomously participate in position determination, thereby improving positioning accuracy and efficiency. At the same time, the saved identity recognition information enables the system to accurately identify the identity of each person going down the well and realize accurate personnel management. The person going down the well carries the UWB positioning tag device, and when the UWB positioning tag device is within the positioning range of the positioning base station, the identity recognition information is sent to the positioning base station, and the position of the UWB positioning tag device is determined together with the positioning base station.

[0031] Preferably, the tag board 120 also includes a radio frequency module and a motion sensing module electrically connected to the main control module 121 , the radio frequency module is used to communicate with the positioning base station, and the motion sensing module is used to sense the movement state of the tag.

[0032] In a preferred embodiment, see Figure 1 The wireless charging module 140 includes a wireless charging coil 141 electrically connected to the main control module 121. The wireless charging coil 141 is used to receive electromagnetic energy by electromagnetic induction and convert the electromagnetic energy into electrical energy to wirelessly charge the rechargeable battery 130. Further, the wireless charging module 140 also includes a receiving circuit electrically connected between the main control module 121 and the wireless charging coil 141. The receiving circuit includes a rectifier, a filter and a voltage regulator. The receiving circuit is used to convert and process the AC signal received from the wireless charging coil 141 to output a stable DC power for the rechargeable battery 130.

[0033] In a preferred embodiment, see Figure 2 and Figure 3The UWB positioning tag device also includes a display screen 160 disposed on the housing 110 and electrically connected to the main control module 121. The display screen 160 is used to display the department, identity information (ID), text information, and battery status information. Specifically, the display screen 160 is an OLED display screen, which reduces the cost and ensures low power consumption. The display screen 160 is located on the front of the housing 110.

[0034] Better, see Figure 2 The UWB positioning tag device also includes an LED indicator light 111 disposed on the housing 110 and electrically connected to the main control module 121. The housing 110 is made of ABS resin material, which has the characteristics of high strength, good toughness, easy processing and molding, and good electrical insulation, ensuring that the UWB signal of the built-in antenna in the structure is not shielded.

[0035] In a preferred embodiment, the tag board 120 uses a low-power chip to extend the power usage time. The tag board 120 is miniaturized and integrated. The tag board 120 integrates a UWB functional circuit to implement the functions and charging methods required by the standard, and to judge and control the battery status.

[0036] In one specific embodiment, see Figure 2 The UWB positioning tag device also includes an alarm button 112 arranged on the housing 110. The alarm button 112 is electrically connected to the main control module 121. By pressing the alarm button, an alarm message can be sent to the positioning base.

[0037] In another specific embodiment, see Figure 4 The UWB positioning tag device also includes an alarm 170 disposed in the housing 110 and used to issue an alarm. The alarm 170 is an audible and visual alarm. The tag board 120 can receive an accident evacuation command from the positioning base station and control the alarm 170 to issue an accident alarm message to remind people to evacuate in time. Figure 5 A sound outlet 113 is provided on the back of the housing 110 .

[0038] In one embodiment, the UWB positioning tag device also includes a detection module electrically connected to the main control module 121, the rechargeable battery 130, the wireless charging module 140 and the charging interface assembly 150. The detection module is used to determine the current charging mode and detect the current battery status. The current battery status includes the current battery voltage and the current battery power. When the current battery voltage is lower than 3.0V, the detection module sends an undervoltage alarm signal to the main control module 121. After receiving the undervoltage alarm signal, the main control module 121 controls the alarm 170 to sound an alarm. Therefore, an alarm is sounded in time when the battery power is low to remind the user to charge in time.

[0039] The communication between the UWB positioning tag device and the positioning base station is described in detail below.

[0040] a. The UWB positioning tag device and the positioning base station can realize two-way communication and data transmission. In the normal state, the information is synchronized first. The synchronization information includes the synchronization clock, data status, etc. to ensure that both parties work at the same time point and data status.

[0041] b. The UWB positioning tag device and the positioning base station establish a connection through handshake. The UWB positioning tag device can actively send broadcast messages so that the positioning base station can detect and identify the tag. The broadcast message includes identity information, etc. The positioning base station can wirelessly change the identity information of the UWB tag through its card reader.

[0042] c. The positioning base station sends a ranging signal to the UWB positioning tag device. The UWB positioning tag device calculates the distance information based on the flight time from the positioning base station to the UWB positioning tag device, and then uploads it to the positioning base station. The positioning base station uploads it to the host computer.

[0043] d. When the host computer sends a command, it first sends it to the positioning base station, which then forwards it to the corresponding UWB positioning tag device. After receiving the command, the UWB positioning tag device performs the corresponding operation and returns confirmation information to the positioning base station.

[0044] The utility model provides a technical solution for a UWB positioning tag device that supports multiple types of charging, proposes an improved charging circuit, adopts a newly designed mold, and makes practical expansion based on an integrated and platform-based design to meet the functions required by the standards.

[0045] 1. The UWB positioning tag device can be charged in the mining lamp charging cabinet or with a conventional mobile phone charger. This flexibility greatly broadens the usage scenarios of the tag without having to worry about the compatibility of the charging equipment.

[0046] 2. The display screen 160 can display the current battery power information in real time, so that the user can intuitively understand the power status of the tag. When the battery power is lower than a certain threshold, the tag will issue a prompt alarm to remind the user to charge in time. This helps to avoid performance degradation or damage caused by over-discharge of the battery, and improves the service life and safety of the tag. In the charging state, the tag can display the charging progress and charging method, so that the user can understand the status and progress of the charging process.

[0047] 3. As it supports multiple charging methods, users do not need to purchase additional dedicated chargers or charging equipment, which greatly reduces the user's investment cost and is more economical and practical.
