Digital train broadcast transmitter control method

Abstract

The invention relates to a method for controlling a broadcasting machine of a digital type in a train. The invention comprises a main program of an industrial control computer of which an automatic broadcasting program of the main program including the following the steps: broadcasting projects and time in the present waiting location are obtained in a broadcasting list; whether the broadcasting time is arrived is determined and if the broadcasting time is not arrived, the program is turned back to beginning and continue; if the broadcasting time is arrived, the present waiting location is moved down to next broadcasting project with concrete appointed time; whether the present system is carrying out broadcasting is examined and if the present system is carrying out broadcasting, an order for stopping broadcasting is released and a broadcasting order as well as the name of a voice document needed to be broadcasted are released too; if the present system is not carrying out broadcasting, an order for starting broadcasting is released and the name of the voice document needed to be broadcasted is transmitted and marked in broadcasting; then the program begins to turn back. Due to adoption of an embedded system of the industrial control computer, the invention stores the broadcasting content in a memory in a digital form and compiles corresponding broadcasting list according to the up and down link time of the train or geographical information. Broadcasting is carried out according to the broadcasting list; artificial mouth broadcasting and artificial intervention are not needed.
