[0036] Embodiment 1

[0037] Figure 1 The architecture diagram of the industrial Ethernet system of the fully mechanized mining face according to the embodiment of the present disclosure is shown as follows: Figure 1As shown, an industrial Ethernet system for a fully mechanized mining face provided by an embodiment of the present disclosure includes:

[0038] A plurality of access devices 1, wherein the access devices 1 are arranged at the fully mechanized mining working face and are used to access the first terminal device of the fully mechanized mining working face;

[0039] A three-layer switch 2 is arranged in the chute, and the three-layer switch 2 is respectively connected to the communication network of the fully mechanized mining face and the communication network connected to the ground communication network;

[0040] NAT device 3, arranged in the chute and connected to the three-layer switch 2, the NAT device 3 separates the underground communication network into an external network and an internal network, the three-layer switch 2 is arranged in the internal network;

[0041] At least one access switch 41, arranged in the intranet and connected to the layer 3 switch 2;

[0042] At least one server 5 is arranged in the intranet, and the server 5 is connected to the access switch 41 .

[0043] Among them, the drift refers to the lanes on both sides of a mining face for people and belt comprehensive mining equipment to enter and exit. The comprehensive mining face is the mining face underground. The communication networks of the drift and the comprehensive mining face together constitute the underground communication network. The ground communication network (or the above-ground communication network) is the public network of the industrial Ethernet system of the comprehensive mining face. The three-layer switch 2 can be linked to the ground communication network to realize the remote control and monitoring of underground coal mining from the ground.

[0044] In this embodiment, according to the physical location of the equipment distribution, the access device 1 is arranged in the comprehensive mining working face. The access device 1 can be an access device for the first terminal equipment such as a video camera, a sensor, and a driver. The access device 1 preferably adopts a ring network connection mode to form a ring network in the comprehensive mining working face to facilitate the reliable communication of each first terminal equipment and subsequent communication with the ground. The access device 1 can also be a controller, which serves as a control access device for the first terminal equipment.

[0045] Video cameras, sensors and other acquisition devices are used to obtain working face data of the comprehensive mining working face (such as the coal mining position and coal mining action of the coal mining machine); the driver can be used as a driving device of the comprehensive mining equipment to drive and control the comprehensive mining equipment, and transmit the working parameters of the comprehensive mining equipment to the access device 1.

[0046] NAT device 3 is used as a boundary protection device, which divides the underground communication network into two parts, an intranet and an extranet, with NAT device 3 as the boundary. The extranet on one side of NAT device 3 is usually connected to the public network, and the other side is the intranet.

[0047] The three-layer switch 2 serves as an aggregation switch, which is respectively connected to the communication network of the comprehensive mining working face (connected to the access device 1), the dedicated line network leading to the ground, and the NAT device 3.

[0048] The access switch 41 is connected to the server 5 and the second terminal device 6 respectively. The access switch 41 serves as an access point for a control terminal or a fully-mechanized mining equipment (including a coal mining machine, a hydraulic support, a scraper, etc.) to meet the access and transmission of a large number of monitoring point data, video surveillance data, etc. in the mine. The access switch 41 can be arranged in the drift or in the fully-mechanized mining working face. The second terminal device 6 and the first terminal device can be at least partially the same, for example, both are control terminals.

[0049] The server 5 can be multiple servers, for example, it can be divided into a work data server and a video server according to the type of transmission data. The server 5 can be arranged in the drift, and can also be arranged in the fully mechanized mining face.

[0050] In this embodiment, the access switch 41 and the server 5 are preferably arranged in the chute, and cooperate with the three-layer switch 2 and the NAT device 3 arranged in the chute to form a chute communication network, ensuring that data is reliably transmitted to the three-layer switch 2 and the NAT device 3, and then transmitted to the ground communication network. The equipment in the chute is connected to the industrial Ethernet system of the fully mechanized working face through the three-layer switch 2.

[0051] When the entire Ethernet system is working normally, the server 5 of the intranet collects and saves the data of various types of equipment and terminals connected in the comprehensive mining automation system, and transmits it to the ground communication network through the access switch 41 and the three-layer switch 2. Corresponding ground switches and ground servers can be arranged on the ground.

[0052] In this embodiment, the three-layer switch 2, access switch 41, server 5, access device 1, etc. are intranet devices. The devices located outside the NAT device 3 (close to the ground) in the slot are extranet devices. All intranet devices are set with private addresses, that is, the intranet addresses are privatized, and only a small number of device addresses are mapped externally through the NAT device 3.

[0053] The industrial Ethernet system for a fully mechanized mining face provided by the embodiment of the present disclosure arranges a plurality of access devices 1 on the fully mechanized mining face to access the first terminal device of the fully mechanized mining face, and arranges a three-layer switch 2 and a NAT device 3 in the chute, the three-layer switch 2 is respectively connected to the communication network of the fully mechanized mining face and the communication network connected to the ground communication network, the NAT device 3 is connected to the three-layer switch 2, the NAT device 3 separates the underground communication network into an external network and an internal network, and the three-layer switch 2 is arranged in the internal network; at the same time, at least one access switch 41 and at least one server 5 are arranged in the internal network, the access switch 41 is connected to the three-layer switch 2, and the server 5 is connected to the access switch 41, the boundary isolation between the internal network and the external network is realized through the NAT device 3, the internal network address is privatized, and only a small number of device addresses are mapped externally, which can improve the stability of the Ethernet system, and the Ethernet system configuration is more standardized, and the configuration is more convenient and reliable; the server 5 is arranged in the internal network of the Ethernet system to collect and centrally store data, and publish data information to the external network through the server 5, and it is only necessary to perform NAT mapping on the server 5, the Ethernet system configuration is simpler, and the maintenance and management of the Ethernet system is also more convenient.

[0054] The industrial Ethernet system of the comprehensive mining working face of this embodiment can establish a simple, convenient and reliable industrial Ethernet communication system underground in the coal mine, communicate with the ground communication network, ensure the fast, stable and reliable transmission of safety detection data, voice data, video surveillance image data, etc., improve the comprehensive automation level of coal mining, and provide safe, efficient and stable communication guarantee for coal mine safety production.

[0055] Optionally, the industrial Ethernet system of the fully mechanized mining working face further includes a mine ring network switch 42 , wherein the mine ring network switch 42 is located in the external network, and the mine ring network switch 42 is connected to the NAT device 3 .

[0056] like Figure 1 As shown, the mine ring network switch 42 is located in the chute, and the NAT device 3 is set between the three-layer switch 2 and the mine ring network switch 42. The mine ring network switch 42 is connected to the ground server of the ground communication network through the mine ring network as an external network device. The mine ring network is formed by the mine ring network switch 42 and the ground switch to realize the connection between the underground communication network and the ground communication network. The mine ring network can reduce the delay and packet loss rate of data transmission, etc., and improve the communication stability and reliability of the industrial Ethernet system of the entire fully mechanized working face.

[0057] In some embodiments, the NAT device 3 includes a configuration module for configuring destination and source NAT rules for the server 5, or configuring NAT rules for a preset terminal device.

[0058] On NAT device 3, destination and source NAT rules are configured for server 5 so that external network devices can communicate with server 5 and obtain required data; NAT rules can also be configured for other specified devices on NAT device 3, which is simple and convenient to configure.

[0059] In some embodiments, the mapping rule by which the intranet device of the intranet is mapped to the external network through the NAT device 3 includes static NAT, dynamic NAT or port NAT.

[0060] Since the number of devices in the intranet that need to be mapped to the external network through NAT is relatively small (at least only servers are needed), the mapping rules give priority to static NAT, that is, the intranet address and the external network address are mapped one-to-one, without port restrictions. Static NAT achieves communication between the internal and external networks by establishing a one-to-one address mapping relationship. Specifically, the private IP address of the intranet device is mapped to a public IP address, so that the intranet device can communicate with the external network through this public IP address. The one-to-one mapping avoids IP address conflicts and duplications, and by mapping the private IP address of the intranet device to a public IP address, the real topology of the intranet and the real IP address of the intranet device can be hidden, thereby improving communication security.

[0061] As can be seen from the above, in the embodiment of the present disclosure, the form of complex port multiplexing is no longer adopted. Instead, the network architecture of the Ethernet system is reasonably planned and designed as a whole, the isolation of the intranet and the extranet is achieved through the NAT device 3, and the centralized collection and management of data is performed by adding devices such as the server 5. Then, the form of static address conversion is adopted, and only NAT mapping is performed on the server 5. One-to-many address conversion is no longer adopted. The configuration of the Ethernet system is simpler and more convenient, and the maintenance and management of the system are also more convenient. After the isolation of the intranet and the extranet, the stability of the Ethernet system is better and the configuration is more standardized.

[0062] In other embodiments, dynamic NAT or port NAT may also be selected when mapping through the NAT device 3 .

[0063] Optionally, the NAT device 3 may also include a firewall module. In this embodiment, the function of the NAT device 3 may be further expanded to enable it to have a firewall function, thereby enhancing the security of the Ethernet system.

[0064] In some embodiments, the three-layer switch 2 includes a VLAN gateway, and the VLAN gateway is connected to the multiple access switches 41. The multiple access switches 41 isolate different types of communication data by broadcast domain by dividing VLAN.

[0065] By setting a VLAN gateway on the three-layer switch 2 of the intranet and dividing VLAN (Virtual Local Area Network) on the access switch 41 of the intranet, different types of video, control, and sensor data are isolated by broadcast domains. Hosts within the VLAN can communicate directly, but hosts between VLANs cannot, which facilitates the transmission of different data in different categories, ensures the accuracy and reliability of data transmission, and avoids data transmission confusion.

[0066] In some embodiments, the network ports of the access device 1, the layer 3 switch 2 and the access switch 41 respectively have wireless AP (Access Point) modules connected to a wireless network.

[0067] like Figure 1 As shown, the devices in the Ethernet system are mainly connected in the form of cables or optical cables, and the communication bandwidth between devices is at least 1000Mbps. The three-layer switch 2, access switch 41, mine ring network switch 42 and other devices with large communication data volume are preferably 10G switches. At the same time, wireless AP modules (also called wireless access points) are set at the network ports of access devices 1 (or controllers) and switch-type devices to ensure reliable communication of the Ethernet system by connecting to wireless networks such as WiFi.

[0068] In some embodiments, the industrial Ethernet system of the comprehensive mining working face includes a network management module, and the network management module manages the devices in the industrial Ethernet system of the comprehensive mining working face through the SNMP protocol.

[0069] The Ethernet system has network management functions. All devices in the system support the SNMP protocol. Running the network management software on the server 5 or a specific terminal (such as the terminal device 6) in the intranet can realize real-time monitoring, display and fault alarm of the operating status of all network devices and network traffic information in the intranet.

[0074] After the access device 1 is connected to the communication network of the comprehensive mining working face, the server 5 in the intranet can collect and save the comprehensive mining working face data of various types of equipment and terminals connected in the comprehensive mining automation system. Then, through the mapping between the server 5 and the NAT device 3, the comprehensive mining working face data is transmitted to the external network, and then transmitted to the ground communication network, thereby realizing data interaction and transmission between the underground communication network and the ground communication network.
