MVB network-based data record analyzer and working method thereof

Abstract

The invention discloses an MVB network-based data record analyzer and a working method thereof. The analyzer comprises an MVB board card, a central processing unit and a computer, wherein the MVB board card is connected with the central processing unit through a PC104 bus; the MVB board card comprises an MVB protocol controller and an MVB bus network interface; the MVB protocol controller is connected with the MVB bus network interface in a two-way communication mode; an ethernet interface is arranged on the central processing unit; the central processing unit is connected with the computer through an ethernet bus; and the computer is provided with special data analysis software. Because of the adoption of the central processing unit with a storage function, the NVB network-based data record analyzer can record train operating data and fault data, and can prevent train faults in time and provide a basis for fault analysis after the occurrence of faults, thereby increasing the reliability of train operation.

Description

technical field [0001] The invention relates to a data record analysis device, in particular to a data record analyzer based on MVB network and its working method. Background technique [0002] In recent years, with the rapid development of the railway industry, fieldbus has become more and more widely used due to its advantages of high reliability, low cost and low failure rate. It occupies a large proportion in the field, especially in the field of rail transportation such as locomotives, bullet trains, and subways, and the application of MVB buses is particularly extensive. With the locomotive structure and equipment becoming more and more complex and the speed increasing, it is required to have higher operational reliability. This requires us to record and analyze the status and fault data of the locomotive during operation through technical means. When the equipment fails, we can find and determine the fault location in time, record the fault process, and provide it to...

AI Technical Summary

Problems solved by technology

[0003] Since there is no data record analyzer based on the MVB network on the locomotive at present, we can only detect the real-time data of the train operation, and cannot record and output these operation data in a delayed manner. Therefore, it is impossible to judge the health status of the train through historical records, and it is impossible to prevent it in advance train breakdown

When a train breaks down, the fault can only be judged based on experience, and there is no basis for operating data, which wastes time for repairing train failures
