[0021] In one embodiment, a knob 13 and an emergency stop switch 14 are provided at the front end of the intrinsically safe panel 4. In this embodiment, a knob 13 and an emergency stop switch 14 are provided at the front end of the intrinsically safe panel. The knob 13 serves as an interface for power supply and parameter setting. The user can turn on the power or adjust relevant parameters by pressing and rotating the knob. This design not only improves the safety of operation, but also makes parameter setting more intuitive and convenient. The emergency stop switch 14 is an emergency brake device. When encountering an emergency or needing to stop the operation of the equipment immediately, the user can quickly cut off the power supply by pressing the emergency stop switch to ensure the safety of the equipment and personnel.

[0022] In one embodiment, an explosion-proof knob 15 is also provided on one side of the box body 1. The design of the explosion-proof knob 15 takes into account the special environment of the coal mine. It allows the user to safely operate the power switch and avoids the safety risks that may be caused by direct operation. By rotating the explosion-proof knob, the user can easily control the power on and off, thereby achieving safe control of the controller.

[0023] In one embodiment, both sides of the box 1 are provided with a threading tube 16 connected to the intrinsically safe chamber 2 and the flameproof chamber 3. The threading tube 16 provides a convenient access channel for external cables, so that the controller can be connected to other devices or systems. At the same time, the design of the threading tube also maintains the integrity of the box, prevents external gas or moisture from entering the box, and ensures the stable operation of the controller.

[0024] In one embodiment, mounting brackets 17 are provided at the upper and lower ends of the inner wall of the flameproof chamber 3, and connecting plates 18 are integrally formed at the middle and both ends of the mounting brackets 17. The battery box 9 is fixed to the connecting plates 18 at the middle of the two mounting brackets 17 by screws, and mounting plates 19 for fixing the power module 10 are connected to both sides of the two mounting brackets 17 by screws. The mounting bracket 17 is fixedly connected to the inside of the box body by the connecting plate 18, providing a stable installation position for the power module 10 and the battery box 9. This design not only improves the stability of the equipment, but also facilitates the maintenance and replacement of the power module and the battery box. At the same time, the integrally formed design of the connecting plate 18 also enhances the stability and reliability of the entire structure.

[0025] In one embodiment, a handle 20 and an antenna 21 are provided at the upper end of the box 1. The design of the handle 20 makes it easier to move and carry the controller underground in a coal mine. Operators can easily lift or drag the controller to adapt to the complex and changeable working environment underground. The introduction of the antenna 21 enhances the remote communication capability of the controller. Through the antenna 21, the controller can wirelessly communicate with the ground control center or other equipment, transmit data in real time, receive instructions, and realize remote monitoring and control.

[0026] In one embodiment, the four corners of the back of the box 1 are provided with fixing lugs 22 for firmly mounting the controller at a fixed position in the coal mine. These fixing lugs 22 are optimized and can adapt to different installation environments and requirements. They not only provide sufficient support, but also allow the controller to be fixed to a wall, bracket or other fixed structure by screws or other fasteners. This design ensures the stability and safety of the controller in the coal mine, and avoids safety accidents that may be caused by shaking or movement of the equipment.

[0027] This application is suitable for the harsh environment of coal mines and can display the voltage and current output status in real time. The following are the specific performance parameters of this application:

[0041] 14. The explosion-proof chamber integrates two sets of intrinsically safe power supplies, one for internal use and one for external output;

[0042] 15. The host has a built-in 4AH intrinsically safe battery that supports more than 4 hours of battery life during power outages.

[0043] Working principle: The present application is composed of a box 1, which is divided into two main parts: an intrinsically safe chamber 2 and a flameproof chamber 3. This design allows the key components inside the controller (such as the power supply and signal processing part) to be physically isolated, reducing the risk of explosive gas directly affecting the internal circuit of the controller. The intrinsically safe chamber 2 and the flameproof chamber 3 are respectively closed by an intrinsically safe panel 4 and a flameproof panel 5, and are fixed by hinges. The joint surface is finely processed to achieve a good sealing effect. This design prevents the sparks that may be generated inside from spreading to the external environment through the gap between the panel and the box, thereby avoiding the possibility of contact with external flammable gases and causing an explosion. A power board 8, a battery box 9 and a power module 10 are installed in the flameproof chamber 3 to provide a stable power supply for the controller. The battery 11 is installed in the battery box 9 and is connected to the power board 8 through the power module 10 to ensure that the controller can continue to work through the backup battery when the main power fails. The power board 8 is connected to the main control board 6 in the intrinsically safe chamber 2 through the wires in the wire tube 12 to achieve safe transmission of power. The main control board 6 is installed in the intrinsically safe chamber 2, which is the core part of the controller and is responsible for signal collection, processing and transmission. Through the display board 7 electrically connected to it, key information such as the opening and closing status of the damper, the operating status of the external device, and the camera shooting picture can be displayed in real time. The front end of the intrinsically safe panel 4 is provided with a knob 13 and an emergency stop switch 14, which is convenient for users to set parameters and emergency stop operations on the controller. The explosion-proof knob 15 set on one side of the box 1 allows the user to safely operate the power switch, avoiding the safety risks that may be caused by direct operation. The two sides of the box 1 are provided with threading tubes 16 to facilitate the access and wiring of external cables while maintaining the integrity of the box. The mounting frame 17 and the connecting plate 18 on the inner wall of the flameproof chamber 3 provide a stable installation position for the power module 10 and the battery box 9, ensuring the stability and reliability of the internal components of the controller. The handle 20 and the antenna 21 at the upper end of the box 1 provide convenience for transportation and remote communication functions respectively. The fixed ear plate 22 on the back of the box 1 allows the controller to be easily installed in a fixed position underground in the coal mine.

In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
