Problems solved by technology

[0005] But there are also disadvantages: the network under test needs built-in bit error rate (BER) measurement function, the workload is heavy, and it cannot be recognized by a third party; for example, mobile phone testing (non-signaling mode), base station testing of 3G/LTE and other communication systems Wait
[0007] But there are ...

Embodiment 1

[0046] Such as figure 1 As shown, this embodiment provides a dual-loop network bit error rate test method. The test method generates a test original data packet and a test start or end signal through a computer. The method includes:

[0047] S101. Parameter data acquisition: Obtain the original test data package (STDP) and test start or end signal generated by the computer, and package and store the original test data package (STDP) and test start or end signal in a local data buffer area; Among them, the test start or end signal is a switch digital signal, so it is referred to as DI signal;

[0048] S102. Parameter processing: if the test start signal is obtained, the original data packet is sent to at least two adjacent network nodes adjacent to the tested network, and at least two adjacent network nodes form a reverse double-loop network ;

[0049] In addition, the above-mentioned original data packet in the reverse dual-ring network, after passing through at least two adjacent n...

Embodiment 2

[0062] The second embodiment further optimizes the test method and test device for the bit error rate of the dual-loop network on the basis of the first embodiment.

[0063] Such as image 3 As shown, the double-loop network bit error rate test method provided in the second embodiment includes:

[0064] S300. Start: start the network error rate test;

[0065] S301. Preset parameters: input the original test data packet and the test start or end signal on the configuration interface of the computer; and the original test data packet includes data content corresponding to one or more network communication protocols; among them, the test start or end signal To switch the digital signal, so it is referred to as DI signal;

[0066] More specifically, such as Figure 4 , Figure 5 As shown, the PC (computer) connected to the test device includes an input keyboard and a display screen; and the PC installation is implemented by C++ technology to implement the operation configuration interface...

Abstract

The invention relates to the technical field of network communication in a nuclear industry and provides a double-loop network bit error rate test method. According to the test method, an original data packet for a test and a test starting or ending signal are generated through a computer. The method comprises the steps of obtaining the original data packet for the test and the test starting or ending signal generated by the computer and storing original data; if the obtained signal is the test starting signal, sending the original data packet to at least two adjacent network nodes adjacent to a tested network, wherein a reverse double-loop network is formed between the at least two adjacent network nodes; after the original data packet passes the at least two adjacent network nodes along two different directions in the reverse double-loop network, generating a target test data packet; and receiving the target test data packet and judging a bit error rate of the reverse double-loop network according to a comparison result of the original data packet and the target test data packet. The problem of testing the bit error rate of the reverse double-loop network can be solved.

Description

Technical field [0001] The invention relates to the technical field of network communication in the nuclear industry, and in particular to a method and device for testing the bit error rate of a double-loop network. Background technique [0002] As digital control systems are more and more widely used in the field of nuclear power, the degree of digitization is getting higher and higher. An important prerequisite for ensuring the application of digital technology is that the network can complete data transmission normally and quickly; and the network error rate The test is to ensure the normal transmission of data in network communication. [0003] The network communication error rate test in the prior art is mainly divided into two test methods: [0004] 1. Single-Ended BER (Single-Ended BER) test. This test method outputs a radio frequency signal through a test instrument or vector signal source, feeds it into the tested network, and the tested network completes the BER test. The ...
