Abstract

The invention discloses a hand-hold portable MVB network data analyzer for locomotive and control method thereof, relates to the application of network system, the analyzer comprises a main controller module composed of AT91SAM7A3, an MVB network protocol control module composed of XC2S50-5TQ1441, an MVB network signal interface unit, a data display control unit and a power supply unit. The MVB network signal is inputted to the MVB network protocol control module from the MVB network bus through the MVB network interface unit, the MVB network protocol control module analyzes the Manchester code signal into standard signal data and then transmits to the main controller module, the data is analyzed, processed and stored in the main controller module, and at last the data by the form of 8 bit parallel port is transmitted to the data display control unit.

Description

technical field [0001] The invention relates to the application of the network system. Background technique [0002] The TCN standard network bus MVB network is a new type of network system dedicated to the railway field. It is adopted by more and more countries in the world because of its reliability and flexibility. [0003] However, due to the strong professionalism of the MVB network (mainly used in some special fields such as railways and some power systems), and the current testing methods and instruments are still very few, especially the portable MVB network analysis equipment suitable for field use is more is blank. [0004] The hand-held portable MVB network data analyzer for locomotives of the present invention is just a data analysis device based on the network system in the railway field—the TCN standard network bus. It is suitable for locomotives with MVB network bus. Contents of the invention [0005] In view of the problems existing in the above-menti...
