Embodiment Construction

[0012] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0013] As shown in Figure 1, the automatic broadcast program flow is as follows:

[0014] (1) Obtain the broadcast item on the current waiting position from the broadcast list, and obtain the broadcast time of the item;

[0015] (2) Judging whether the broadcast time has arrived, if not, return to the beginning to continue;

[0016] (3) If the broadcasting time has arrived, move the current waiting position down to the next broadcasting item with specific designated time;

[0017] (4) Check whether the current system is broadcasting, if so, issue an instruction to stop broadcasting, and then issue an instruction to start broadcasting, and simultaneously transmit the names of each voice file that needs to be broadcasted; the mark is already broadcastin...

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.

Description

technical field [0001] The invention belongs to a broadcasting device, in particular to a control method of a digital train broadcasting machine for automatic broadcasting of train broadcasting. Background technique [0002] The current train broadcasting machine is an analog type and only artificial mouth broadcasting, the broadcasting work has a large workload, is prone to fatigue and mistakes, and does not have the conditions for automatically playing digital audio. Contents of the invention [0003] The invention provides a control method of a digital train broadcasting machine capable of automatically broadcasting in order to solve the technical problems in the known technology. [0004] The technical scheme that the present invention takes for solving the technical problem that exists in the known technology is: it includes the main program of industrial control computer, also includes automatic broadcasting program, and its concrete steps are as follows: [0005] (...
