[0046] Example

[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a mine communication system based on a time-sensitive network, including a power box and a hydraulic support controller;

[0048] The power box includes a power module and a TSN switch, wherein the power module is electrically connected to the TSN switch. The TSN switch has a time-sensitive network function, is used to process communication data, and provides a communication network port to the outside.

[0049] Specifically, the mining communication system further includes a camera, and the camera is connected to the hydraulic support controller.

[0050] Specifically, the explosion-proof type of the power box is flameproof and intrinsically safe.

[0051] Specifically, the mining communication system also includes a sensor and a WiFi base station. The sensor is connected to the hydraulic support controller. The sensor and the WiFi base station are both electrically connected to the power module. The power module provides power for TSN switch modules, hydraulic support controllers, cameras, sensors, WiFi base stations and other equipment.

[0052] The mining communication system also includes a 5G CPE, which is connected to the power module.

[0053] Specifically, the TSN switch and the hydraulic support controller each have two network ports for automatic networking, one network port is used to connect to an upstream device, referred to as an upstream port, and the other operation port is used to connect to a downstream device, referred to as a downstream port.

[0054] The power module has the function of converting 127V AC power into 12V DC intrinsically safe power, and outputs no less than 5 intrinsically safe power supplies for use by other loads in the comprehensive mining working face.

[0055] The TSN switch module has no less than 6 network ports and supports 100Base T1 and 1000Base T1 protocols.

[0056] The TSN protocols supported by the switch include but are not limited to IEEE802.1Qbv, IEEE1588, IEEE802.1Qci, IEEE802.1CB, IEEE802.1Qbu, and IEEE802.1 Qcc.

[0057] The mine communication system includes a plurality of power supply boxes and a plurality of hydraulic support controllers.

[0058] The switches in the power box are strictly connected in a chain topology. The power box not only provides power to the controller, but the TSN switches in it also receive and forward network data sent by the controller.

[0059] In the fully mechanized mining face, multiple power boxes are cascaded through network ports to build a TSN backbone network. Other loads, including but not limited to network cameras, hydraulic support controllers, WiFi base stations, 5G CPE, sensors, etc., are connected to the power box TSN switch through the network port. The TSN switch will identify the network data of different loads according to its own configuration, and use different processing mechanisms for the network data of different loads to ensure the deterministic transmission of key traffic.

For the convenience of description, the TSN switch directly connected to the first-level TSN switch port is recorded as a second-level TSN switch. According to this rule, the second-level TSN switch continues to send automatic encoding configuration messages to the next-level TSN switch directly connected to the second-level TSN switch port, and configures the IP address of the next-level TSN switch until the next-level TSN switch is a terminal device, completing the configuration of the IP addresses of all TSN switches.

[0071] The first-level hydraulic support controller sends an automatic coding configuration message to the hydraulic support controller directly connected to the first-level hydraulic support controller port, and configures the IP address of the hydraulic support controller directly connected to the first-level hydraulic support controller port. For the convenience of description, the TSN switch directly connected to the first-level TSN switch port is recorded as the second-level TSN switch here; according to this rule, the second-level hydraulic support controller continues to send automatic coding configuration messages to the next-level hydraulic support controller directly connected to the second-level hydraulic support controller port, and configures the IP address of the next-level hydraulic support controller until the next-level hydraulic support controller is a terminal device, and the configuration of the IP addresses of all hydraulic support controllers is completed.

[0072] It should be noted that the automatic encoding configuration messages sent by the TSN switch and the hydraulic support controller are different each time, and the automatic encoding configuration messages are generated according to preset rules.

[0073] The TSN switch and hydraulic support controller complete the automatic encoding function of the device and configure the IP address of the TSN switch and hydraulic support controller by sending automatic encoding configuration messages to similar devices directly connected to their upstream ports and downstream ports in the system (except the main controller).
