[0002] In the current communication technology field, for Ethernet data transmission, the main method currently used is to connect Ethernet data to the data processing system and then parse and process the data. There are various processing methods, but no matter which processing method is used, the ultimate goal is to connect the Ethernet data that needs to be monitored and transmitted to the processing equipment to complete the subsequent analysis, processing and transmission. However, the data input and output methods (TCP or UDP) and the specific information of the data (IP information and port information) cannot be set according to the needs. Only data processing and monitoring effects can be achieved, and the specific information of the data cannot be clearly understood. In addition, the number of data access paths is limited, which has certain limitations. Summary of the invention

Its purpose is to provide a transmission device and an implementation method that can transmit one or more Ethernet data, in view of the current problems of long-distance Ethernet data transmission, such as limited transmission paths, low data transmission efficiency, inability to obtain data-related information, and uncontrollable data input and output methods.

[0004] The device consists of a multiplexing terminal device and a tapping terminal device. The multiplexing terminal device can set the input mode and specific information of the input Ethernet data according to requirements and establish corresponding connections. The data processing system can monitor and process the data based on this information; the tapping terminal device can set the data output mode and specific information of the data receiving end according to requirements and establish corresponding connections, and complete the data output.

[0035] The branch terminal device is composed of a main control chip II, a touch screen II2-1, a control network port II2-2, a data network port II2-3 and a digital optical port II2-4 arranged in a shell II2.

[0037] The touch display screen II2-1 is arranged on the front panel of the shell II2, and the control network port II2-2, the data network port II2-3 and the digital optical port II2-4 are arranged on the rear panel of the shell II2.

[0038] The models of main control chip I and main control chip II are both ZYNQ 030.

[0039] The user can use the host computer Ⅰ to establish a TCP connection with the multiplexing end device through the control network port Ⅰ1-2 and realize remote control. The user can also use the touch screen Ⅰ1-1 to establish a TCP connection with the multiplexing end device through the control network port Ⅰ1-2 and realize local control. Use the host computer Ⅱ to establish a TCP connection with the tapping end device through the control network port Ⅱ2-2 and realize remote control. The user can also use the touch screen Ⅱ2-1 to establish a TCP connection with the tapping end device through the control network port Ⅱ2-2 and realize local control.

[0040] The Ethernet data is input through the data network port Ⅰ1-3 of the multiplexing terminal device. After receiving the Ethernet data, the main control chip Ⅰ analyzes and processes the data and sends it to the digital optical port Ⅰ1-4. Finally, it is sent through the digital optical port Ⅰ1-4 in the form of an optical signal.

[0041] The branch terminal device receives the optical signal from the multiplexing terminal device through the digital optical port II2-4, analyzes and processes the optical signal, restores it to the Ethernet data input by the multiplexing terminal device, and finally sends it through the data network port II2-3.

[0042] like Figure 2 and Figure 4 As shown, the touch screen Ⅰ1-1 and the touch screen Ⅱ2-1 can set the network information of the control network port, the network information of the data network port and the IP information, port and rate of multiple Ethernet data.

[0043] like Figure 3 and Figure 5 As shown, the data network port Ⅰ1-3 of the multiplexing end device is used to establish a TCP or UDP connection with the Ethernet data input end and receive Ethernet data; the data network port Ⅱ2-3 of the branching end device is used to establish a TCP or UDP connection with the data receiving end and send Ethernet data.

[0044] The multiplexing terminal device is controlled by the host computer I and the touch screen Ⅰ1-1 through the control network port Ⅰ1-2, and the branching terminal device is controlled by the host computer Ⅱ or the touch screen Ⅱ2-1 through the control network port Ⅱ2-2.

[0045] The digital optical ports Ⅰ1-4 of the multiplexing terminal equipment are used for outputting the optical signals after the multiple Ethernet channels are integrated; the digital optical ports Ⅱ2-4 of the demultiplexing terminal equipment are used for receiving the optical signals.

[0046] Figure 6 This is a functional diagram of the touch screen. The functions of the host computer are the same as those of the touch screen.

[0047] like Figure 7 and Figure 8 As shown, the implementation method of the Ethernet data transmission device based on the Linux system, the steps are as follows:

[0048] The overall process of Ethernet data transmission is as follows: after the multiplexing end device and the tapping end device are started, the remote host computer Ⅰ of the multiplexing end device and the local touch display screen Ⅰ1-1 establish a network connection with the main control chip Ⅰ through the control network port Ⅰ1-2. The user can set the input method of Ethernet data, such as TCP method, IP information and port number. The remote host computer Ⅱ of the tapping end device and the local touch display screen Ⅱ2-1 establish a network connection with the main control chip Ⅱ through the control network port Ⅱ2-2. The user can set the output method of Ethernet data, such as TCP method, IP information and port number.

[0049] The multiplexing end device will first start the corresponding TCP Server thread according to the multiple IPs and port numbers. When a connection is established with the TCP Client and data is transmitted, the touch screen Ⅰ1-1 and the host computer Ⅰ will display the corresponding rates. When this information is changed on the touch screen Ⅰ1-1 or the host computer Ⅰ, the main control chip Ⅰ will change and save it accordingly. For channels where the IP or port has changed, the main control chip Ⅰ closes the original TCP connection and establishes a new TCP connection to receive data from the data end in a timely manner.

[0050] After receiving Ethernet data through the data network port Ⅰ1-3, it is integrated and output in the form of optical signals through the digital optical port Ⅰ1-4.

[0051] The tap-end device will first start the corresponding TCP Client thread to establish a connection with the TCP Server according to the multiple IP and port numbers. When there is a signal input at the digital optical port Ⅱ2-4, the tap-end device will send the parsed data from the data network port Ⅱ2-3 to the data receiving end through TCP communication. The touch screen Ⅱ2-1 and the host computer Ⅱ will display the corresponding rate. When the information is changed on the touch screen Ⅱ2-1 or the host computer Ⅱ, the main control chip Ⅱ will be changed and saved accordingly. For the channel with changed IP or port, the main control chip Ⅱ closes the original TCP connection and establishes a new TCP connection to send the data to the receiving end in time. The main control chip Ⅰ and the main control chip Ⅱ of the multiplexing end device and the branching end device can save and monitor the network information of the control network port of the device. When this information is changed on the touch screen Ⅰ1-1 or the touch screen Ⅱ2-1 or the host computer Ⅰ or the host computer Ⅱ, the main control chip will be changed and saved accordingly, and the device will automatically restart. After that, the main control chip re-establishes the connection with the touch screen Ⅰ1-1 or the touch screen Ⅱ2-1 and the host computer Ⅰ or the host computer Ⅱ, and can save and monitor the network information of the data network port. When this information is changed on the touch screen Ⅰ1-1 or the touch screen Ⅱ2-1 or the host computer Ⅰ or the host computer Ⅱ, the main control chip will be changed and saved accordingly, and the corresponding TCP connection will be changed accordingly.

[0052] The above steps are for when the Ethernet transmission mode is TCP. The steps are the same when the Ethernet transmission mode is UDP.
