Description
technical field [0001] The invention relates to the field of embedded network equipment, in particular to a digital broadcast control system applied to trains. Background technique [0002] In the modern train broadcasting system, the digital broadcasting controller, as the auxiliary control device of the TMS signal, is an important part of the passenger broadcasting system. [0003] The digital broadcast controller can complete the interaction between the subway driver's cab and the ground control center, broadcast to the train carriage, intercom with passengers, cab intercom, real-time display of TMS information, train fault and fault removal guidance display and other functions. During the operation, the driver can broadcast station announcements, emergency broadcasts and mouth broadcasts in real time through the LCD screen. When there is a passenger intercom request, the driver can also decide to connect the passenger's request on the LCD screen according to the order o...
