Voice broadcasting method and voice broadcasting system of industrial control system

Abstract

The invention provides a voice broadcast method and broadcast system for an industrial control system, and the method comprises the steps: obtaining the current alarm information of the industrial control system according to a broadcast application instruction; acquiring alarm variable information from the alarm information, wherein the alarm variable information at least comprises an alarm type and an alarm variable value; converting the alarm information into a text according to the alarm variable information and a preset information text conversion rule corresponding to the alarm variable information, and storing the text into a preset file library as a newly added text; obtaining a newly added text from the preset file library according to the updating information of the preset file library; and converting characters in the newly added character text into voice, and carrying out voice broadcast. By utilizing the invention, the problems that the alarm system of the existing industrial control system broadcasts according to the pre-recorded audio file, the form is single, if a certain alarm character is changed, the alarm character needs to be recorded again, and meanwhile, the real-time alarm of the analog quantity cannot be realized can be solved.

Description

technical field [0001] The invention belongs to the technical field of industrial control alarms, and more specifically relates to a voice broadcast method and a broadcast system of an industrial control system. Background technique [0002] In the field of industrial control, WinCC (Windows Control Center), as a human-machine interface component, has been widely used in industrial sites at the same time as the PLC control system. The on-site data is displayed by the WinCC host computer, and the important data is alarmed at the same time. [0003] At present, the voice alarm system of the WinCC system has the following implementation methods, one is to use its own alarm to configure, and when the alarm enters, play the pre-selected sound file in mav format; the other is to use the script to call the API function PlaySoundA To play sound files in mav format. These two methods can only play a fixed voice, which can be a sound file recorded in advance, or a single alarm sound...
