Data recording device of network control and monitoring system of train

Abstract

The invention discloses a data recording device of a network control and monitoring system of a train, belonging to the technical field of rail transportation. The data recording device can adapt to severe environments of vibration, high temperature and the like during running of the train, and has the advantages of simple structure, low cost, large storage capacity, relatively high reliability and the like. The data recording device of the network control and monitoring system of the train comprises a CPU unit, an interface unit, a logical unit and a storage unit, wherein the CPU unit is connected with the interface unit, the logical unit and the storage unit respectively; the interface unit is used for receiving data from the network control and monitoring system of the train and comprises an MVB bus interface module and an MVB bus control module, and the MVB bus control module is connected with the CPU unit and is used for monitoring the MVB bus interface module; the logical unit is used for adjusting the time sequence of the MVB bus control module to ensure that the time sequence of the MVB bus control module is matched with that of the CPU unit; and the storage unit comprises a CF card for storing the data from the network control and monitoring system of the train.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a data recording device for a train network control and monitoring system. Background technique [0002] The train network control and monitoring system is mainly used in locomotives, bullet trains, subways and other fields. It plays a key role in system integration in the on-board electrical system and plays a central role in the system. It adopts distributed control technology and includes a series of modules or devices, among which the data recording device plays a vital role as a device for recording train operation safety-related data. [0003] With the rapid development of rail transit technology, the speed of train passenger transportation has also been rapidly improved. At the same time, people have higher requirements for the performance of the data recording device in the train network control and monitoring system, which is specifically reflected in the increasin...
