Method for controlling broadcast system by telephone and its control device

Abstract

The present invention relates to a control method of broadcasting system using a telephone and control device thereof. The method comprises the steps of: connecting to a tone detector of the control system by switching a hook switch when a bell signal transmitted by a call of the subscriber is detected more than a set number; after the connection step, sending a previously recorded guidance voice to the subscriber under control of a central processing unit and detecting telephone button signals generated by a manipulation of the subscriber by frequency values of tone frequency; determining which broadcast region the subscriber wants based on the telephone button signals and driving corresponding relays; and connecting electrically the broadcasting system to a broadcast destination of the selected broadcast region to broadcast speech signals to the broadcast destination, the speech signals being sent from the subscriber. A control device corresponding to said method comprises: a bell signal detector (20) connected to a telephone line (10) for detecting bell signals that ring by a set number; a central processing unit (50); a tone detector (30); a broadcast equipment controller (60); and an output controller (70).

Description

technical field [0001] The present invention relates to a method for controlling a broadcasting system by using a telephone and a control device thereof, in particular to such a method for controlling a broadcasting system and a control device thereof, that is, a small-scale broadcasting system can be controlled by using a telephone, so that without specialized knowledge, Make convenient and ideal broadcasting. Background technique [0002] In a large-scale broadcasting system, especially a broadcasting system in a parking lot area or a department store, the system is operated under the control of some professionals in the broadcasting field. However, in the case of small-scale broadcasting systems, especially those used in companies or schools, it is not possible to employ professionals in these broadcasting fields, so that the employees of companies or schools have to operate broadcasting incidentally in addition to their own duties. system. Therefore, if certain employe...

However, in the case of small-scale broadcasting systems, especially those used in companies or schools, it is not possible to employ professionals in these broadcasting fields, so that the employees of companies or schools have to operate broadcasting incidentally in addition to their own duties. system

Therefore, if some employees are incidentally operating the PA system while doing their job, the PA system cannot operate while the employees are doing their own job

For example, in a school, if the teacher in charge of the PA system is teaching students in the classroom, and other teachers cannot operate the PA system, then the PA system will not work

[0003] In fact, since the broadcast system is relatively complex, with multiple control devices for amplifiers and microphones and multiple switches for selecting broadcast targets, the operator must carefully understand the configuration of each device and broadcast target
