Abstract

The invention provides a synchronous tunnel video display system, which comprises a power supply module, a master server, a human-computer interaction module, a plurality of display modules, a plurality of synchronization modules and a communication module, wherein the master server is used for producing a play image; the plurality of display modules are arranged in a plurality of train running tunnels, and are used for displaying video image information; the plurality of synchronization modules are used for ensuring the synchronization of a train running state and information displayed by the display modules; the communication module transmits data produced by the master server to the display modules; the synchronization module further comprises a plurality of speed testers and a synchronization signal processor; the speed testers are arranged between two metro stations, and are uniformly distributed in the tunnels between the two stations of a train, and when detecting the passage of the train, transmit the information to the synchronization signal processor respectively; the synchronization signal processor performs calculation to obtain a synchronization control signal, transmits the synchronization control signal to the display modules; and the display modules display the video image information according to the instruction of the synchronization control signal. The synchronous tunnel video display system has the advantages of synchronous display capability and high definition.

Description

technical field [0001] The invention relates to the field of tunnel video display, in particular to a high-definition video display system that can be used in subway operation and can be synchronized with train operation. Background technique [0002] Due to its fast, convenient and low-cost advantages, the subway has increasingly become the preferred mode of transportation for people to travel. Taking Beijing as an example, there are about 7 million passengers every day, while the Tokyo subway has 8 million passengers every day. For passengers who take the subway for a long time, the journey in the subway becomes very boring because there are no entertainment facilities. By virtue of this, placing advertisements or entertainment programs in the subway can not only bring relaxation to the journey of passengers, but also bring greater attention and popularity to the advertisers with the help of the large traffic of the subway, thus Bring economic benefits. [0003] At prese...
