DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In view of the problems existing in the above-mentioned technologies, the embodiments of the present utility model provide a positioning card reading base station. Figure 1 This is a schematic diagram of a positioning card reading base station of the utility model. Figure 2 For the logic block diagram of the positioning card reading base station of the utility model, see Figure 1 and Figure 2The positioning card reading base station includes: a first board component 110, a second board component 120 and a third board component 130. The first board component 110 includes a main control module 112 and a positioning module 113. The first board component 110 is connected to a battery through a first power management circuit 140. A first switch K1 is provided on the circuit between the first power management circuit 140 and the third board component 130. The second board component 120 includes other modules 122. The second board component 120 is connected to a battery through a second power management circuit 150. A second switch K2 is provided on the circuit between the second power management circuit 150 and the second board component 120. The third board component 130 includes a switch module 132. The third board component 130 is connected to the battery through the third power management circuit 160. A third switch K3 is provided on the circuit between the third power management circuit 160 and the third board component 130. The third switch K3 is connected to the first switch K1, the second switch K2 and the third switch K3 through the control of the main control module 112, so that the main control module 112 can control the opening and closing of the first switch K1, the second switch K2 and the third switch K3.

[0032] In this embodiment, the internal board is designed in a fusion mode, and the fusion board is formed by the first board 110, the second board 120 and the third board 130. The first power management circuit 140, the second power management circuit 150 and the third power management circuit 160 are used to respectively power the functional modules on the first board 110, the second board 120 and the third board 130, and each board is equipped with an independent power management circuit and an independent switch to control the on and off of the power supply. This scheme adopts multi-level power management, and the first switch K1, the second switch K2 and the third switch K3 are uniformly controlled by the main control module 112 on the first board 110. When the voltage is supplied, the main control module 112 collects the battery voltage information in real time. If the collected voltage is less than the set voltage threshold or the power supply discharge time is greater than the set discharge time, the main control module 112 controls the second switch K2 to close, and cuts off the power supply voltage of other modules 122, thereby ensuring that the important components of the switch and the positioning module 113 are continuously powered for a long time. This solution achieves a rational structural layout through integration, reduces wiring, and solves the problems of existing equipment with messy internal structure, high power consumption, and no power classification function.

[0033] In a preferred embodiment, see Figure 1 and Figure 2The first board component 110 also includes a first board body 111, a card reader module, and a communication module. The main control module 112, the positioning module 113, the card reader module, and the communication module are arranged on the first board body 111. Specifically, the main control module 112, the positioning module 113, the card reader module, and the communication module are plugged and connected to the first board body 111. The main control module is responsible for the control and management of the entire base station. The main control module includes functions such as data processing, communication control, and positioning algorithms. The card reader module is a radio frequency card reader module and is used to read the information of the radio frequency positioning card carried by each miner. The positioning module 113 is a radio frequency positioning module and is used to locate the tag and determine the position of the tag relative to the positioning card reading base station. The communication module includes an RS485 unit and an RS232 unit. The communication module is used to communicate with the host computer and transmit the read tag information and positioning data to the monitoring device.

[0034] In a specific embodiment, see Figure 1 and Figure 2 The second board component 120 also includes a second board body 121, and other modules 122 are arranged on the second board body 121. The other modules 122 are plugged and connected to the second board body 121. Specifically, the other modules 122 include at least one of a WIFI module and a 4G module. The WIFI module is used to enable the positioning card reading base station to connect to other devices or networks through a wireless network. The 4G module is used to provide the positioning card reading base station with the ability of mobile data communication.

[0035] In a specific embodiment, see Figure 1 and Figure 2 The third board component 130 further includes a third board body 131, and a switch module 132 is disposed on the third board body 131. The switch module 132 is plugged and connected to the third board body 131. The switch module 132 is used to achieve high-speed and stable data exchange within the positioning card reading base station or between other devices.

[0036] In this embodiment, different functional modules are designed to be pluggable and installed on the board, so that the configuration of the functional modules on the entire board is more flexible. When a functional module needs to be added or replaced, it is only necessary to operate the corresponding functional module alone, without disassembling the entire board. This design makes the replacement, upgrade and maintenance of the functional modules simple and fast. At the same time, the plug-in connection also ensures the connection stability and data transmission efficiency between the module and the board body. Multiple functional modules are integrated on a board, reducing complexity and space occupation. The modular design makes maintenance and troubleshooting easier. When a module has a problem, the faulty module can be quickly located and replaced, reducing maintenance costs and time.

[0037] In one embodiment, see Figure 2 , the positioning card reading base station also includes at least two antennas 170 connected to the positioning module 113. Antenna 170 is used to receive the wireless signal sent by the tag, and may also be used for positioning function. By configuring at least two antennas 170, the positioning card reading base station can receive the wireless signal sent by the tag more stably, reduce the recognition failure or error caused by signal interference or attenuation, and improve the stability and accuracy of the received signal. The difference between the signals received by different antennas 170 can also be used to improve the positioning accuracy. Even if one antenna 170 fails or its performance degrades, the other antennas 170 can still work normally to ensure the normal operation of the entire system and the continuity of data.

[0038] In yet another embodiment, see Figure 1 and Figure 2 The positioning card reading base station also includes an external interface module 180 connected to the switch module 132. Specifically, the external interface module 180 includes a bus interface 183 and an HDMI interface 187 connected to the first board component 110, and a plurality of optical ports 181 and a plurality of electrical ports 182 connected to the third board component 130, and the access mode can be flexibly selected according to the on-site wiring application.

Figure 4 This is a side view of the positioning card reading base station of the utility model, see Figure 3 and Figure 4 The positioning card reading base station further comprises a box 190, which comprises a lower shell 191 and an upper cover 192. One side of the upper cover 192 is rotatably mounted on one side of the lower shell 191 through a hinge 193, and the other side of the upper cover 192 is detachably connected to the other side of the lower shell 191 through a locking member 194. Preferably, the first board component 110, the second board component 120 and the third board component 130 are located in the box 190, the external interface module 180 is arranged on the lower shell 191, and the box 190 is also provided with a handle 195. The lower shell 191 is also provided with a first interface 184 connected to the first power management circuit 140, a second interface 185 connected to the second power management circuit 150, and a third interface 186 connected to the third power management circuit 160. The first interface 184, the second interface 185 and the third interface 186 are respectively connected to the battery through cables. The optical port 181, the electrical port 182, the bus interface 183, the first interface 184, the second interface 185 and the third interface 186 all adopt aviation docking interfaces, which eliminates the need to open the cover on site and can be directly used for aviation plug-in docking on site, thereby increasing the protection performance of the product.

[0040] In a specific embodiment, see Figure 3 and Figure 4The positioning card reading base station also includes a first connecting plate 1911 disposed on the other side of the lower shell 191 and a second connecting plate 1921 disposed on the other side of the upper cover 192. The first connecting plate 1911 is provided with a first threaded hole, and the second connecting plate 1921 is provided with a second threaded hole. The locking member 194 is threadedly connected in the first threaded hole and the second threaded hole.

[0042] The utility model proposes a technical solution for a positioning card reading base station supporting power management, which has the following beneficial effects:

[0043] 1. Adopt integrated fusion board design: Integrate modules with different functions into one board to reduce the complexity of internal layout and wiring problems. Compared with the existing combination and stacking of multiple functional boards, the integrated design can achieve a reasonable layout of the internal structure, reduce wiring confusion, and improve the stability and maintainability of the overall system. Modules with different functions can be flexibly selected and plugged in as needed, which improves the flexibility and scalability of module configuration and reduces costs.

[0044] 2. The positioning card reader base station adopts an intrinsically safe design. The electric sparks and thermal effects generated in normal operation or fault conditions cannot ignite the specified explosive mixture, which greatly improves the safety of the product in flammable and explosive environments. It can meet the strict safety requirements for electrical equipment in mines, allowing the positioning card reader base station to operate safely and stably in multiple locations in mines, reducing the risk of accidents caused by electrical failures.

[0045] 3. Multi-level power management: The main control module 112 monitors the power supply voltage and discharge time of each board, and controls the power supply priority of internal modules. When the backup battery voltage is low, the power supply of key components is prioritized, ensuring the safety of production management.

[0046] 4. The dual antenna 170 design can enhance the receiving capability of the positioning module 113 for tags, improve positioning accuracy and stability, and is suitable for positioning requirements in complex environments. The design of two antennas 170 can achieve redundant backup. Once one antenna 170 fails, the system can still work normally, which improves the reliability and stability of the system.
