Abstract

Currently, most LED controllers for the metro carriage display are driven directly by I/0 of MCU and the display interface is very simple, therefore it´s difficult to meet the multiform requirements of video terminal. In order to meet this requirement, this paper designed the software system of new type metro display LED controller based on Ethernet, analyzed its function and achieved an implementation. This new type metro display LED controller takes Linux and Qt system as a developing platform and communicated with TCMS in process data and message data through the Ethernet. This new type metro display LED controller has been applied to a driverless metro and the result shows that its response speed is fast and its display effect tends to be diversiform.
