Module Introduction With the development of the embedded Microcomputer Control Technology and the Fieldbus Technology, the Process Control for the modern train has developed from the centralized Direct Digital Control (DDC) system to the Distributed Control System (DCS) which is based on the network. MVB (Multifunction Vehicle Bus) which is based on the distributed control is a recommended project of IEC61375-1(1999) TCN (Train Communication Network). MVB possesses the features of high real time and reliability. According to the modernization development trade of the train and vehicles and the requirements of the reliability, safety and communication real time, MVB will gradually become the communication bus standard of the next generation vehicles. Application Field It is applied in varieties of carriages of the train to make the equipments within the carriages connect with each other. 【DOWNLOAD】
