[0021] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0022] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] like Figure 1 As shown, a safety monitoring system for on-site mine workers includes a positioning base station, positioning tags, an alarm device, and a control terminal; the positioning base station is fixedly installed in the mine operation area; the alarm device includes an audible and visual alarm and a vibration module.

[0024] Multiple positioning tags are attached to the workers' belongings, and these tags are wirelessly connected to the positioning base station; the control terminal is located in the mine monitoring center and is connected to the positioning base station via a wired network.

[0025] Preferably, since all workers must wear safety helmets at the work site, attaching the positioning tag to the helmet can prevent workers from becoming separated from the positioning tag, thereby ensuring that personnel at the mine monitoring center can obtain the location of workers through the positioning tag and positioning base station.

[0026] When in use, after the worker wears the positioning tag and enters the mining work area, the positioning tag sends a signal to the surrounding positioning base stations through the wireless communication module. The antenna array of the positioning base station receives the signal and transmits it to the signal processing unit. The signal processing unit calculates the positioning tag's location information based on the signal's arrival time and strength. The location information is transmitted to the control terminal through a wired network. The control terminal determines whether the worker is in a dangerous area based on the preset danger zone range. If the worker enters a dangerous area, the control terminal sends an alarm command to the audible and visual alarm and the vibration module through the remote control module. The audible and visual alarm is activated to remind the surrounding personnel to take precautions, and the vibration module is activated to remind the worker wearing the positioning tag to evacuate the dangerous area. At the same time, the control terminal displays the worker's real-time location on the screen so that the management personnel can monitor the situation on site.

[0027] Preferably, the positioning base stations are fixedly installed on the top or side wall of the mining operation area. They are installed in an open space to facilitate signal reception and transmission, and there are multiple positioning base stations evenly distributed in a grid pattern.

[0028] In some embodiments of this utility model, the positioning base station includes a housing, a signal processing unit, an antenna array, and a power supply module;

[0029] The housing is a rectangular box structure with a mounting groove on its rear wall. A mounting plate is embedded and fixed in the mounting groove. Several bolt holes are evenly distributed on the surface of the mounting plate. The signal processing unit is fixed in the middle of the housing cavity and connected to the housing with screws. The antenna array includes four directional antennas, which are fixed at the four corners of the front wall of the housing, and the included angle between two adjacent directional antennas is 90°. The power module is fixed at the bottom of the housing cavity and electrically connected to the signal processing unit through wires.

[0030] The rectangular enclosure structure offers high stability and space utilization. Combined with mounting slots and embedded mounting plates on the rear wall, it provides excellent protection for internal components while facilitating installation and maintenance. This allows the positioning base station to be easily fixed to walls or other supporting structures, and the bolt hole design further enhances the installation's robustness.

[0031] Four directional antennas are fixed at the four corners of the front wall of the housing, with a 90° angle between adjacent antennas, achieving 360° omnidirectional signal coverage. This ensures uniform signal distribution, improving positioning accuracy and signal reception range. Furthermore, the directional antennas concentrate the signal in a specific direction, reducing signal diffusion loss and increasing signal strength and transmission distance compared to omnidirectional antennas. The power module is fixed at the bottom of the housing cavity and electrically connected to the signal processing unit via wires. This prevents interference from other components, facilitates heat dissipation, and improves the reliability and lifespan of the power module.

[0032] The entire base station has a compact structure and a reasonable layout of components, which saves space and facilitates integration and maintenance. Moreover, since each component is fixed in the housing through modular design, it can be easily upgraded or replaced in the future as needed, such as replacing the signal processing unit or antenna with a higher performance one.

[0033] The front wall of the positioning base station housing has heat dissipation holes arranged in a honeycomb pattern. The depth of the mounting groove on the rear wall of the housing is one-third of the housing thickness. The mounting plate surface has four bolt holes arranged in a rectangular pattern.

[0034] In some embodiments of this utility model, the positioning tag includes a shell, a main control chip, a wireless communication module, a battery, and a vibration module. The shell has a cuboid structure and a slot on its top surface for engaging and fixing with the edge of a safety helmet. The main control chip is fixed in the middle of the inner cavity of the shell and connected to the wireless communication module via a flexible circuit board. The wireless communication module is fixed on one side of the inner cavity of the shell and communicates with the positioning base station via an antenna. The battery is fixed at the bottom of the inner cavity of the shell and electrically connected to the main control chip via a wire. The vibration module is fixed on the other side of the inner cavity of the shell and electrically connected to the main control chip via a wire.

[0035] The rectangular shell structure offers high space utilization and structural stability, effectively protecting the internal components. The slots on the top surface are designed for secure engagement with the helmet's edge, allowing for easy and secure installation of the positioning tag. This ensures the tag is firmly attached and won't easily fall off, making it particularly suitable for industrial settings or situations requiring helmet use.

[0036] The main control chip is located in the center of the inner cavity of the housing and is connected to other modules via a flexible circuit board. This effectively reduces the impact of external shocks and vibrations on the main control chip, while the flexible circuit board improves the reliability and flexibility of the connection. The wireless communication module is fixed to one side of the inner cavity and communicates with the positioning base station via an antenna. This ensures that the antenna has sufficient space for signal transmission and reception, reduces signal interference, and improves the stability and reliability of communication. The wireless communication module can communicate efficiently with the positioning base station to achieve real-time transmission of positioning data, ensuring the accuracy and real-time performance of the positioning system. The battery is fixed at the bottom of the inner cavity and electrically connected to the main control chip via wires. This prevents the battery from being squeezed or interfered with by other components, facilitates heat dissipation, and extends battery life. The battery provides stable power support for the entire positioning tag, ensuring that the tag can work normally during long-term use. The vibration module is fixed to the other side of the inner cavity and electrically connected to the main control chip via wires. This ensures that the vibration module can respond promptly to the instructions of the main control chip when needed. The vibration module can be used to alert the wearer, for example, when the positioning signal is weak, when entering a dangerous area, or when receiving an emergency command, by vibrating to remind the wearer to take appropriate measures, improving safety and user experience.

[0037] This utility model features a compact positioning tag with a rationally arranged component layout, saving space and facilitating integration and maintenance. Furthermore, the components are modularly designed and fixed within the outer shell, allowing for easy upgrades or replacements as needed in the future, such as replacing the wireless communication module or battery with a higher-performance one. This utility model effectively improves personnel safety and management efficiency. Moreover, the tag is secured to a safety helmet via a slot, ensuring it won't detach during operation and enhancing wearing safety. The vibration module's alert function promptly notifies the wearer, preventing them from missing important information due to noise or limited vision, further improving user experience and safety.

[0038] Furthermore, the inner wall of the slot on the top surface of the positioning tag is provided with a rubber pad, and the rubber pad is 2mm-3mm thick. A charging interface is provided on the bottom surface of the outer shell, and the charging interface is electrically connected to the battery. An indicator light is provided on the side of the outer shell, and the indicator light is electrically connected to the main control chip through a wire.

[0039] In some embodiments of this utility model, the control terminal includes a host, a display screen, and input devices.

[0041] Furthermore, the control terminal's host has an internal storage module, which is connected to the host via a data cable. The storage module is used to store the location information of the operators and alarm records.

[0042] In some embodiments of this utility model, the positioning base station and the positioning tag transmit data through UWB wireless communication technology. The positioning base station receives the signal emitted by the positioning tag and calculates the location information of the positioning tag through the signal processing unit. The location information is transmitted to the control terminal through a wired network. The control terminal determines whether the worker is in a dangerous area based on the location information and displays the real-time location of the worker on the display screen.

[0043] In detail, based on the characteristics of UWB, UWB technology provides high-precision positioning, which can accurately determine the location of workers.
