Embodiment approach 1

[0034] This implementation mode provides an Ethernet-based self-checking optical fiber data unidirectional transmission method, such as figure 1 shown, including:

[0035] Step S1: Use a splitter to divide the optical signal sent by the sending end into a first optical signal and a second optical signal.

[0036] Step S2: return the first optical signal to the sending end, and send the second optical signal to the receiving end; the sending end verifies the first optical signal according to the verification protocol.

[0037] The first optical signal and the second optical signal split by the splitter have the same information. The sending end can be a host computer with an optical fiber network card, the receiving end can be a lower computer with an optical module, and the splitter can be a fiber optic splitter. After the second optical signal is sent to the receiving end, the receiving end can convert the second optical signal into an electrical signal and store it in the ...

Embodiment 1

[0041] In this example, the specific transfer process is:

[0042] Step 1: The upper computer sends data through the optical fiber network card, and the optical fiber network card converts the electrical signal into an optical signal through the optical module, and the optical signal is divided into the same two channels through the optical fiber splitter.

[0043] Step 2: All the way is captured by the lower computer and stored in the buffer.

[0044] Step 3: The other way returns to the optical fiber network card, and the host computer program accepts it, and verifies the data according to the verification protocol. If the verification is successful, continue to send, and if the verification fails, resend.

[0045] If the transmitted data does not need to be verified, step 3 can be omitted.

[0046] The remarkable effect of this embodiment is that, using the characteristics of the optical fiber network card having the function of self-sending and self-receiving, the optical...

Embodiment approach 2

[0048] This embodiment provides an Ethernet-based self-checking optical fiber data one-way transmission system, such as figure 2 As shown, it includes the sending end, the splitter and the receiving end; the sending end is used to transmit the optical signal to the splitter; the splitter is used to divide the optical signal from the sending end into the same two paths, and the first path returns to the The sending end, and the sending end checks; the second transmission is to the receiving end.

[0049] The sending end can be a host computer with an optical fiber network card, and the receiving end can be a lower computer with an optical module. The receiving end is also used to convert the second optical signal into an electrical signal and store it in the buffer. The principle of this embodiment is the same as that of Embodiment 1.

Abstract

The invention aims to solve problems in the prior art that one-way transmission does not have a verification function and a development checking module has defect of increasing the development difficulty and cost of a lower computer. The invention provides a self-checking optical fiber data one-way transmission method and system based on Ethernet. The method comprises: using a deconcentrator for dividing optical signals sent by a sending end into first-path optical signals and second-path optical signals; returning the first path of optical signal to the sending end, and sending the second path of optical signal to the receiving end; and the sending end verifying the first path of optical signal according to the verification protocol. The system comprises a sending end, a deconcentrator and a receiving end, wherein the sending end is used for transmitting an optical signal to the deconcentrator. The deconcentrator is used for dividing the optical signal from the sending end into two identical paths, the first path returns to the sending end, and the sending end verifies the optical signal. The second path transmits to the receiving end. The method is suitable for the field of Ethernet high-speed data transmission.

Description

technical field [0001] The invention relates to the technical field of Ethernet high-speed data transmission, in particular to an Ethernet-based self-checking optical fiber data unidirectional transmission method and system. Background technique [0002] In the prior art, there are mainly the following ways for the upper computer to transmit data to the lower computer: [0003] 1. Based on serial port transmission, the feature is that it does not require too many external devices, but the disadvantage is that the transmission rate is small, and it is mostly used for data interaction of control commands; [0004] 2. Based on Ethernet transmission, this transmission method has the advantage of fast transmission speed, but this method requires the lower computer to have a network card chip, which can complete the handshake communication with the upper computer, which makes the development of the lower computer difficult and costly, which affects the transmission speed; [0005...
