WORLDFIP data recording unit for locomotive and working method thereof

Abstract

The invention discloses a WORLDFIP data recording unit for locomotive and a working method thereof. The unit comprises a WORLDFIP protocol controller, a WORLDFIP bus transceiver and a WORLDFIP transformer isolator, wherein the WORLDFIP protocol controller is bidirectionally connected with a high-speed singlechip and a PC104 bus interface through an internal bus in sequence; the PC104 bus interface and the PC104 bus of a PC104 X86 interface card are bidirectionally connected through the internal bus; and the output end of the PC104 X86 interface card is connected with the input end of a data storage unit. In the invention, the high-speed singlechip is responsible for controlling the working time sequence of the WORLDFIP protocol controller and the generation of a PC104 data stream, and data are sent to the data storage unit to be stored and recorded after being processed by the PC104 X86 interface card. The invention has the advantages of high reliability, flexibility and generality, low cost and the like.

Description

technical field [0001] The invention relates to a locomotive network control device based on WORLDFIP network technology, in particular to a WORLDFIP data recording unit for locomotives and a working method thereof. Background technique [0002] The WORLDFIP network is a network specially designed for locomotive and vehicle buses. It has become a high-reliability fieldbus network widely used abroad and at home. It is an important part of the IEC61375-3 standard. However, due to its strong professionalism, The external interface is not particularly convenient. [0003] Data recorder is a data storage device that is widely used on rolling stock at present. It is generally placed in the driver's cab to facilitate maintenance personnel to download and analyze data. When the vehicle is returned to the warehouse, the maintenance personnel can download the faults and vehicle operation files stored in the data recorder, and use the relevant upper computer analysis software to make ...

AI Technical Summary

Problems solved by technology

However, due to the special applicability of rolling stock, many core technologies are monopolized by foreign countries, resulting in very expensive foreign data recorders

Moreover, the structure and function of foreign data recorders cannot fully meet the needs of users. Many users have a lot of needs. They need the scalability of the recording unit and the interface of the data recording unit to be changed. However, foreign manufacturers have never met the needs of users.
