Real-time Ethernet device performance test method, device and system

Abstract

The present invention provides a real-time Ethernet device performance test method which is applied to a test device. The method comprises the steps of: receiving a test example sent by a test upper computer; according to the test example, sending a delay test request message to a monitored device, receiving a delay test reply messages sent by the monitored device, and / or receiving a stability test message sent by the tested device; according to the delay test request message and the delay test reply message, sending delay test data to the test upper computer through a preset timestamp interface, and / or according to the stability test message, sending stability test data to the test upper computer through a preset interface message error interface or a receiving message correction messageto allow the test upper computer to perform analysis to obtain a test result according to the delay test data and / or the stability test data. The method provided by the invention achieves the Ethernetstability device and the delay test of the monitored device and mainly a terminal-type device.

Description

technical field [0001] The present application relates to the technical field of testing, in particular to a method, device and system for testing the performance of real-time Ethernet equipment in trains. Background technique [0002] The current train real-time Ethernet is still a relatively new technology, and has not yet been widely used in practice. With the development of train real-time Ethernet bus technology, more and more real-time Ethernet devices will be used on trains. As a brand-new communication protocol, real-time Ethernet for trains must be verified and tested in different degrees and aspects before it is applied to trains. [0003] The real-time Ethernet equipment that has passed the conformance test and function test needs to be tested for performance, including stability test and delay test, before being applied to trains. However, in the testing status of real-time Ethernet devices, most of them only realize the conformance test and function test for r...

Problems solved by technology

However, the functions and characteristics of switching devices and terminal devices are different. Switching devices are only used to forward data. The forwarded message returns to the test device, but the terminal device needs to perform data processing. If the performance test of the terminal device is performed in the same way, the test message carried by the terminal device will cause the terminal device to fail to recognize the message. Therefore, the performance test method for switching equipment cannot be used for performance testing of Ethernet terminal equipment. It can be seen that the performance test for real-time Ethernet terminal equipment is still blank
