Design Of Driver Display Unit For Metro Based On MVB

Subway train driver display unit is an equipment of the train network control system, mainly used for train drivers and train running information of human-computer interaction. The driver display unit is capable of real-time display of the in-vehicle device of a train, train basics and recorded Driving failure and other important parameters to directly reflect the changes in the way to a combination of graphics, symbols, text, color, etc.; the device also has some instructions to send the property, the driver is able to display unit to send commands to the vehicle equipment test train recognized before driving the train equipment. The visible driver display unit is essential to the normal operation of the train driver display unit has far-reaching practical significance.Domestic driver display unit development is lagging behind, and as the train network control system equipment, in the actual subway project applications, often with a complete suite of network control system directly introduced, which the day-to-day maintenance and futurethe development work has brought great difficulties. Therefore, the driver display the unit localization of an increasing demand, we need to speed up its own study, master the core technology, and dependence on foreign technology. The subject comes from the actual project, the paper from the hardware platform integrated development and driver display unit software development these two angles comprehensive exposition of the system implementation process. Hardware integration, including the demand for hardware platforms, the selection of the microprocessor, the MVB network card, Ethernet card module; Software development include the realization of the principle of the research on MCGS MVB equipment components and MCGS configuration software driver display unit interface. Online testing is carried out on the driver display unit in the last chapter, the central control unit of the laboratory with the driver display MVB bus connected through custom variables and properly configured logical address by the central control unit to the driver display unit hairdata through observation, showing good results, and various functions can be well meet.The driver display unit has a stable working performance, feature-rich, and easy secondary development, in line with the actual engineering requirements. At the same time, China has accelerated the independent research and development driver display unit to provide some reference.
