Abstract

The invention belongs to the technical field of embedded computers, and relates to a train digital broadcast controller based on HomePlug. The train digital broadcast controller comprises a main control module and a communication module. The main control module is composed of a main control chip and a peripheral circuit thereof, the main control module is responsible for the initialization of a train digital broadcast system, clock synchronization, fault monitoring and management, control and processing of audio and video streams, and operation of an MVB network high layer protocol. The communication module is composed of a USB submodule, a HomePlug power line carrier network submodule, an Ethernet submodule, an RS232 submodule and an MVB submodule. The communication module provides data access portals for log recording of network communication and the train digital broadcast system, program update and the debugging of the train digital broadcast controller. The functional modules workin coordination to form a complete train digital broadcast controller. The train digital broadcast controller provided by the invention can be applied in the fields of bullet trains, city subways, light rails or the like of the rail traffic system.

Description

technical field [0001] The invention belongs to the technical field of embedded computers, and relates to a train digital broadcasting controller based on HomePlug. Background technique [0002] The emergence and development of train digital broadcasting system cannot be separated from the rapid development of train communication network technology. In recent years, in the practical application of the train communication network, the scheme of using TCN (Train Communication Network) to form the control network and industrial Ethernet to form the multimedia information network has become the mainstream. Because of TCN's advantages in network real-time and reliability, it will also occupy a dominant position in the train control network for a long time. With the application of multimedia technology in the train broadcasting system, the network communication volume has increased significantly, and the application of industrial Ethernet in the train communication network is inc...
