Problems solved by technology

If there is a communication failure on a certain MVB port of the terminal device, the main control device cannot determine whether there is a problem with the command execution or channel acquisition of the terminal device.
When the port communication failure is serious, it will endanger the safety of the train

Abstract

A communication port fault detection method comprises a communication port fault detection method for terminal equipment and a communication port fault detection method for main control equipment, andthe communication port fault detection method for the terminal equipment comprises the steps of monitoring a communication state of a to-be-tested port; if the test data is not monitored from the to-be-tested port within the first preset duration, configuring fault flag bit data corresponding to the to-be-tested port as first flag bit data; and generating corresponding feedback data according tothe fault mark data of the to-be-tested port and the life signal of the terminal equipment, and sending the feedback data to the main control equipment, so that the main control equipment determines the fault state of the to-be-tested port according to the feedback data. According to the method, the main control equipment can accurately determine the communication state of each port of the terminal equipment, so that the fault state of each equipment in the communication network can be detected more accurately.

Description

technical field [0001] The present invention relates to the field of MVB communication technology, in particular to a communication port fault detection method, in particular to a communication port fault detection method for terminal equipment and a communication port fault detection method for master control equipment. Background technique [0002] The traditional MVB communication fault is to judge whether the terminal equipment is online through the life signal port of the terminal equipment. When the long-time life signal port does not update, the main control device will report the communication failure of the terminal device. [0003] The disadvantage of this method of communication diagnosis is that it can only feed back the online status of a certain terminal device, and cannot accurately reflect the communication status of a specific port. However, each terminal device actually has many different ports, and these ports involve important information such as control...
