[0078] The fourth receiving unit is configured to receive the result of establishing the communication link of the closed device from the transparent proxy module.

[0079] As shown in Figures 1 and 2, the specific working principles are as follows:

[0080] S01: Establish a communication link.

[0081] The embodiment of the present application involves a remote master station, a transparent proxy module and a protection device of a substation. A transparent proxy module is deployed in a substation gateway machine, and a TCP link is established with the master station using the dispatching data network IP of the substation gateway machine.

[0082] The remote master station has access to various protection protocols. When a new substation needs to be connected, all configuration work must be completed at the remote master station according to the substation protection device situation, including the network IP address of each protection and the communication protocol used.

[0083] It should be noted that the master station and the transparent proxy module communicate using a dedicated communication protocol, which is a private protocol specifically customized to meet the functional requirements of the master station and the transparent proxy module. The protocol between the transparent proxy module and the protection device includes a standard protocol or a private protocol of the protection manufacturer.

[0084] After the remote master station is configured, as shown in S01 in Figure 1, the remote master station starts the process of establishing a communication link. The remote master station first establishes a TCP link with the transparent proxy module of the substation gateway machine, and then establishes a communication link with the protection device, as follows:

[0085] (1) The master station sends a TCP connection establishment signal to the transparent proxy module. After receiving the TCP connection establishment signal from the master station, the transparent proxy module establishes a TCP connection with the master station and then sends the result of the TCP connection establishment to the master station.

[0086] (2) After the TCP link is established, based on the requirements of the protection communication protocol, the master station sends one or more commands to establish a protection device communication link to establish communication links with different port numbers or different link types.

[0087] The command for establishing a communication link with the protection device includes the IP address, port number and link type of the protection device; the transparent proxy module establishes a communication link with the protection device based on the above information, and performs a communication link number on the communication link to obtain a communication link number corresponding to the communication link; then the result of establishing the communication link with the protection device is sent to the master station, wherein the result of establishing the communication link with the protection device includes the communication link number corresponding to the communication link.

[0088] S02: Transparent transmission of data.

[0089] As shown in S02 in FIG1 , after the communication link between the remote master station and the transparent proxy module is established, the transparent data transmission process is started.

[0090] The remote master station organizes communication messages based on the protection device's communication protocol and sends a first-data forwarding command according to the dedicated communication protocol. Upon receiving this first-data forwarding command, the transparent proxy module forwards the first-data forwarding command to the corresponding protection device. Similarly, upon receiving the second-data forwarding command from the protection device, the transparent proxy module organizes a second-data forwarding command and sends it to the remote master station. The transparent proxy module's relay agent function enables bidirectional communication between the remote master station and the protection device.

[0091] It should be noted that the protocol first data forwarding command sent by the remote master station includes the protocol first data and the communication link number of the corresponding protection device. The transparent proxy module finds the corresponding protected communication link according to the "communication link number" in the protocol first data forwarding command, and forwards the protocol first data to the corresponding protection device through the communication link.

[0092] After receiving the second protocol data and its communication link number from the protection device, the transparent proxy module organizes the data into a second protocol data forwarding command and sends it to the master station. The second protocol data is organized according to the protection device's protocol, which may be a standard protocol or a proprietary protocol of the protection vendor.

[0093] S03: Close the communication link.

[0094] As shown in S03 in FIG1 , the remote master station may initiate a process of closing the communication link as needed.

[0095] When the remote master station needs to close the communication with a protection device, it sends a command to close the protection device communication link to the transparent proxy module. The transparent proxy module disconnects the communication link with the protection device and then sends the result of closing the device communication link establishment to the master station.

[0096] It should be noted that, in response to the interruption of communication between the master station and the transparent proxy module, the transparent proxy module disconnects the communication links with all protection devices.

[0097] The above embodiment achieves the transparent transmission effect shown in Figure 2. The substation gateway transparent proxy module has only one physical link with the remote master station, and the substation gateway transparent proxy module establishes an independent physical link with each protection device. Through the transparent proxy module, all protection device physical link messages are mapped to the physical link between the same transparent proxy module and the remote master station, enabling the remote master station to "directly" access the protection device without being restricted by the protection protocol.

[0098] In one embodiment, a method for transmitting remote protection information based on a transparent transmission link is provided, which is configured as the transparent proxy module of the aforementioned embodiment, including the following steps:

[0099] Sending the first protocol data to the corresponding protection device according to the first protocol data forwarding command;

[0100] After receiving the protocol second data and its communication link number sent by the protection device, it sends a protocol second data forwarding command to the master station;

[0101] The protocol first data forwarding command includes the protocol first data and the communication link number of the corresponding protection device; the protocol second data forwarding command includes the protocol second data and the communication link number of the corresponding protection device.

[0102] In one embodiment, a method for transmitting remote protection information based on a transparent transmission link is provided, which is configured as the master station of the aforementioned embodiment, including the following steps:

[0103] Sending a first data forwarding command to the transparent proxy module;

[0104] receiving a second data forwarding command sent by the transparent proxy module;

[0105] The protocol first data forwarding command includes the protocol first data and the communication link number of the corresponding protection device; the protocol second data forwarding command includes the protocol second data and the communication link number of the corresponding protection device.
