[0019] Reference Figure 1-2A centralized control computer for coal mines comprises an intrinsically safe cavity 4 and a flameproof cavity 2 arranged inside a box assembly 1, wherein an intrinsically safe module assembly is arranged in the intrinsically safe cavity 4, and a flameproof module assembly is arranged in the flameproof cavity 2, and the intrinsically safe module assembly and the flameproof module assembly are physically connected via a flameproof network through-wall terminal and a flameproof signal through-wall terminal arranged on the box assembly 1; the intrinsically safe module assembly comprises a WIFI6 control mainboard, a LORA wireless transmission module, a current loop communication module, and an IO control module; the flameproof module assembly comprises an industrial tablet computer, a PLC control host, an intrinsically safe power supply module, a communication isolation module, an isolation coupling module, an industrial router, an industrial Ethernet switch, and a network isolation module; the modules are connected to each other by means of a CAN bus, and the industrial tablet computer and the PLC control host are connected by means of gigabit optical communication or Ethernet electrical signal communication.

[0020] The intrinsically safe module assembly is set up to realize functions such as data acquisition, transmission, control and human-computer interaction.

[0021] The flameproof module assembly is used to realize the functions of logical control, storage, call and query of data. By integrating the flameproof chamber with the intrinsically safe chamber, it can be directly applied to coal mines with gas and coal dust explosion hazards. The flameproof technology and intrinsically safe technology are combined in an integrated way, which not only ensures the safety of the system, but also improves the integration. The volume of the flameproof chamber is reduced, the weight of the product is reduced, and the application of multiple modules also effectively reduces the number of equipment in the working face control room, so that the system can be better optimized and managed.

[0022] The flameproof cavity is physically connected to the flameproof module assembly in the intrinsically safe cavity and the module assembly in this case through the flameproof network through-wall terminal and the flameproof signal through-wall terminal, ensuring that the energy can be effectively isolated and evacuated when a potential explosion occurs.

[0023] Modules communicate with each other via CAN bus, making data transmission more stable and reliable; computers and other control devices or switches communicate via Gigabit optical communication or Ethernet electrical signals, which have stronger anti-interference capabilities.

[0024] The explosion-proof module assembly has two control hosts, industrial tablet computers and PLC control hosts. The PLC control host mainly collects data from the underground coal mine centralized control system for logic control. The industrial tablet computer is mainly used to send configuration data of each subsystem of the centralized control system, display the software interface, store data, call and query data, etc. The intrinsically safe power supply module is used to power the intrinsically safe part of the module. Various isolation modules are used to distinguish between intrinsically safe and non-safe isolation signals, which is safe and reliable.

[0025] The back of the box assembly 1 is provided with a WIFI communication interface, a LORA wireless interface, a current loop interface, and an IO interface connected to the WIFI6 control mainboard, the LORA wireless transmission module, the current loop communication module, and the IO control module on one side of the intrinsically safe cavity 4. The multiple control interfaces set by the centralized control computer can meet different control requirements.

[0026] The box assembly 1 is provided with an intrinsically safe keyboard 5 connected to the intrinsically safe module assembly outside the intrinsically safe cavity 4. The intrinsically safe keyboard is an essential tool for user human-computer interaction and facilitates the operation of the centralized control computer.

[0027] The intrinsically safe module assembly also includes a voice intercom module, which is used to speak to people along the belt or working surface, and can be used in conjunction with the IP phone of the ground centralized control center and the dispatching center to conduct emergency broadcasts along the line.

[0028] An explosion-proof glass window 3 for observing the explosion-proof module assembly is provided on the front side 1 of the box assembly and on one side of the explosion-proof cavity 2 .

[0029] A sealing strip is provided between the explosion-proof glass window 3 and the box assembly 1 .

[0030] The back of the box assembly 1 is provided with a plurality of socket cable assemblies 6 connected to the flameproof module assembly on one side of the flameproof cavity 2. The socket cable assembly is used to directly connect to a network switch or a hydraulic support controller, and is directly led out from the flameproof cavity, which can reduce on-site wiring of the equipment.
