Design and implementation of Train-Borne Announcement System Controller

Along with the development of train communication network, Train-Borne Announcement System Controller (TASC) has become an essential part of the underground and city rail vehicle. According to this requirement and based on the multifunction vehicle bus standard, this paper presents the general design, hardware buildup and software implementation of the TASC. The TASC has perfect functions, transmits data fast and correctly, and satisfies the real time requirement of the train control and manage system. The TASC has applied successfully to a line of Guangzhou underground and runs stably.
