[0022] Understandably, the power circuit board is pluggable in the power area of ​​the base plate 2, and the core circuit board 16 is pluggable in the core area 29 of the base plate 2. Each functional circuit board is pluggable in its corresponding functional area of ​​the base plate 2. This realizes the modular integrated design of the monitoring and control substation, thereby effectively reducing the size of the substation and facilitating its installation and use. At the same time, multiple power lines and multiple communication lines on the base plate 2 are used to achieve electrical connection, avoiding the layout of additional cables, thereby reducing circuit nodes, improving signal transmission efficiency and stability, and contributing to the improvement of equipment reliability, maintenance efficiency and system response speed in the intelligent construction of mines.

[0023] It should be noted that the substation in this embodiment integrates commonly used circuits, and each module is plug-and-play. Electrical connections are achieved using the base plate 2, resulting in higher signal transmission rates and system reliability. Furthermore, it is easy to replace damaged modules. Modules can be selected according to actual needs, thereby reducing costs. This makes the monitoring substation highly reliable, environmentally adaptable, and easy to maintain, making it suitable for complex underground environments.

[0025] The base plate 2 is used for the integrated layout of the power supply circuit board, the core circuit board 16, and various functional circuit boards. The specific type of the base plate 2 can be set according to actual needs and is not limited thereto. For example, the base plate 2 has a multi-layer PCB layout, with power supply traces and communication traces arranged on the surface or inside of the base plate 2. High-speed communication between various modules can be achieved using a unified bus (TTL, SPI, I2C). The base plate 2 has a front and back side in opposite positions. Each area is located on the front side of the base plate 2, and the four sides of the front side of the base plate 2 are the front end, rear end, left end, and right end in opposite positions.

The specific types of the first power module 4, the second power module 5, and the third power module 6 can be set according to actual needs and are not restricted.

[0034] For example, the first power module 4 converts the externally input 18V voltage to 9V voltage (first voltage), the second power module 5 converts the 9V voltage of the first power module 4 to 5V voltage (second voltage), and the third power module 6 converts the 9V voltage of the first power module 4 to 3.3V voltage (third voltage).

[0044] It is understandable that the first communication circuit board 9 is pluggably mounted in the first communication area 26 of the base plate 2, and is electrically connected by the sixth power supply line, the second communication line, the third communication line, and the sixth power supply line on the base plate 2, thereby realizing the modular integrated design of the substation and ensuring the reliable operation and convenient use of the substation.

[0052] It should be noted that the third communication circuit board 11 is used for communication between the core circuit board and the external RS485 communication module. The specific type of the third communication circuit board 11 can be set according to actual needs and is not limited thereto. Specifically, there are six third communication circuit boards 11, and the third communication area 28 of the six second communication circuit boards 10 arranged on the base plate 2 can be located on both sides of the center of the base plate 2.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the monitoring and control substation further includes: a top plate 3, a display circuit board 12, and a display screen 13.

The display circuit board 12 is pluggably disposed in the display area, and the display screen 13 extends to the side of the top plate 3 away from the bottom plate 2. The display circuit board 12 and the second power module 5 are connected by a first power wire, and the display circuit board 12 and the core circuit board are connected by a first communication wire.

[0054] Understandably, because the display circuit board 12 is pluggable and located in the display area of ​​the top plate 3, and is electrically connected using the first power wire, the first communication wire, etc., the modular integrated design of the substation is realized, ensuring the reliable operation and convenient use of the substation.

[0055] It should be noted that the top plate 3 is used to arrange the display circuit board 12, the display screen 13, etc. It is stacked with the floor, which can make full use of the thickness space of the outer shell 1 and reduce the space occupied in the plane direction of the outer shell 1.

The cover 102 is provided with a light-transmitting area 103, and the display screen 13 is located in the light-transmitting area 103.

[0063] It is understandable that, since the cover 102 is movably mounted on the housing 101 and covers the opening of the housing 101, the display screen 13 is located in the light-transmitting area 103 of the cover 102, which allows the housing 1 to facilitate the disassembly and assembly of various modules by utilizing the cooperation between the cover 102 and the housing 101. At the same time, the display screen 13 can be displayed by utilizing the light-transmitting area 103, making the use of the substation more convenient.
