Network communication quality detection method and system, train display screen and storage medium

Abstract

The invention discloses a rail transit vehicle network communication quality detection method and system, and the method comprises the steps: creating a file on a train display screen, selecting a to-be-detected port, receiving network data through the to-be-detected port according to a sampling period, and when the network communication of the to-be-detected port is changed from normal to abnormal, sending the to-be-detected port to a server; recording the abnormal time point as the current abnormality occurrence time, wherein the current abnormality occurrence frequency is equal to the sum of the last abnormality occurrence frequency and 1; when the network communication of the to-be-detected port is changed from the abnormal state to the normal state, recording the time point when the network communication is changed to the normal state as the current abnormal end time, calculating the current abnormal duration time, the previous abnormal duration average time, the current longest abnormal duration time and the current shortest abnormal duration time, and storing data; according to the method, an additional special test instrument does not need to be accessed, disassembly and access of the vehicle network equipment are avoided, and the detection cost and the detection workload are reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle communication detection, and in particular relates to a method, system, train display screen and storage medium for network communication quality detection of rail transit vehicles. Background technique [0002] At present, the conventional on-board subsystems of the rail transit vehicle control network include power pack system, super capacitor system, traction system, auxiliary system, braking system, pantograph system, emergency broadcast system, air compressor system, door system, Air-conditioning system, passenger information system, fire alarm system, running part detection system, etc. At the same time, with the continuous development of rail transit technology and the introduction and popularization of the concept of smart transportation, urban rail transit vehicles have more and more functions and are more and more humanized. Correspondingly, the number of on-board subsystems loaded on t...
