[0017] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments in conjunction with the accompanying drawings, in which:

[0019] Figure 2 It is a structural diagram of a multifunctional module integration according to one embodiment of the utility model. DETAILED DESCRIPTION

[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following describes an intrinsically safe base station for mining proposed according to an embodiment of the present invention with reference to the accompanying drawings.

[0022] Figure 1 The figure is a schematic structural diagram of a mine-used intrinsically safe base station according to an embodiment of the present utility model.

[0023] like Figure 1As shown, the intrinsically safe base station for mining includes a functional circuit, a CAN interface is provided on one side of the functional circuit, one end of the functional circuit is connected to one end of the radio frequency circuit, the other end of the radio frequency circuit is connected to the antenna, the other side of the functional circuit is provided with Ethernet and CPRI interfaces, one side of the other end of the functional circuit is connected to the positive pole of the multi-way power supply, and the same side of the other end of the functional circuit is connected to the negative pole of the multi-way power supply.

[0024] In one embodiment of the present invention, the multi-channel power supply is a mining flameproof and intrinsically safe DC regulated power supply.

[0025] Specifically, the KDW660 / 12B(E) mining flameproof and intrinsically safe DC regulated power supply is a universal flameproof and intrinsically safe uninterruptible power supply approved for use in hazardous environments with gas and coal dust explosion hazards. It is suitable for powering intrinsically safe mining equipment. It employs dual overcurrent and overvoltage protection to ensure that the output meets intrinsically safe performance requirements.

[0026] Specifically, KDW660 / 12B(E) is used to provide power to intrinsically safe equipment in mines where there are dangers of methane and coal dust explosions.

[0027] Specifically, this power supply utilizes a flameproof housing with a hook on the top. The front cover is hinged to the housing for easy opening. The battery is controlled by a knob, which must be operated with the housing closed. Turning the knob to "on" activates battery power; turning it to "off" automatically shuts off the battery. This power supply has a dual-chamber design, and cables connecting to associated devices are routed directly into the chamber and connected to the corresponding terminals on the terminal block.

[0028] Figure 2 This is a schematic diagram of the integrated structure of functional modules, such as Figure 2 As shown, it includes an integrated module circuit of a UWB positioning module, a traffic light control module and a network switch module.

[0029] Specifically, one end of the UWB positioning module circuit is connected to one end of the traffic light control module circuit, and the other end of the traffic light control module circuit is connected to the network switch module.

[0030] For example, the network switch module is the communication hub of the system, responsible for the rapid exchange and transmission of data. It can connect various devices, such as UWB positioning modules, traffic light control modules, sensors, and cameras, ensuring efficient and secure data flow between them. The network switch module also provides network management and security functions, forming the cornerstone of the stable operation of the entire system.

[0031] For example, the UWB (Ultra-Wideband) positioning module provides highly accurate location information. In traffic management systems, UWB technology can be used to track the locations of vehicles and pedestrians in real time, helping the system make location-based decisions, such as dynamically adjusting the timing of traffic lights to optimize traffic flow and reduce congestion.

[0032] For example, the traffic light control module is the core of the traffic signal control system, dynamically adjusting the timing of traffic lights based on traffic flow, pedestrian activity, and emergency situations. In an integrated system, the traffic light control module can receive real-time location data from the UWB positioning module, as well as information from other sensors such as vehicle flow and pedestrian counts, to intelligently adjust traffic lights to ensure smooth and safe traffic.

[0033] The integrated system combines a network switch module, a UWB positioning module, and a traffic light control module to achieve the following: Dynamically adjust traffic light signals based on real-time traffic flow and location information, reducing congestion and improving traffic efficiency. The UWB positioning module detects the location of pedestrians and vehicles, and the traffic light control module adjusts signals accordingly to ensure their safety. In emergency situations, such as traffic accidents or emergency vehicle traffic, the system can quickly adjust signals to create a safe passage for emergency vehicles. The extensive data collected by the integrated system can be used to analyze traffic patterns, identify bottlenecks, and optimize traffic planning and signal control strategies. The UWB positioning module can also be used in smart parking lots, providing vehicle navigation and parking guidance, improving parking efficiency.
