The present invention relates to a power consumption control system using matrix diversification broadcasting.

Generally, buildings with multiple compartmentalized spaces, such as schools, buildings, government offices, and apartments, are equipped with a voice broadcasting system to deliver notification messages to people in each compartment and to transmit an emergency alarm in the event of an emergency. there is.

Taking schools as an example, the operation of the audio broadcasting system within the school is carried out independently in the broadcasting room, auditorium, gymnasium, audiovisual room, music room, etc., and in most schools, one broadcasting teacher manages all the school's broadcasting equipment. .

To operate this voice broadcasting system, speakers are installed in separate spaces such as classrooms, teachers' offices, playgrounds, auditoriums, and science rooms for each grade and class, and amplifiers, microphones, audio, etc. that supply voice signals of appropriate sizes to these speakers. The sound source generator is installed in the control room.

A typical voice broadcasting system consists of a sound source generator, an amplifier that amplifies and outputs the voice or sound signal output through the sound source generator, and a speaker that transmits the amplified signal output from the amplifier so that humans can hear it. . In addition, a speaker selection unit is provided that electrically connects or disconnects the speaker and the amplifier so that voice or sound signals are selectively output through a desired speaker.

Meanwhile, a public address system refers to a broadcasting system that can deliver sound to a limited range of the public through a one-to-many communication method. The main function of this type of public address system is to receive information from the fire reception center in the event of a fire and make fire emergency announcements for the purpose of protecting people, so it is installed in almost all buildings in accordance with the Fire Service Act.

In addition, the public address system is not only used for single simple buildings, but also for buildings that require free regional (class-specific) broadcasting such as elementary/middle/high schools, large-scale buildings such as intelligent complex buildings (IBS: Intelligent Building System), and public address broadcasting systems. Broad applicability is required to respond to a wide range of uses, such as buildings such as military bases that must be able to broadcast by large, medium, and small units through interconnection.

In addition, in response to consumer convenience demands, free expandability is required to enable the use of a wider variety of sound sources and outputs, including not only emergency fire broadcasting but also microphone broadcasting, reservation broadcasting, and background music broadcasting from many remote locations.

In other words, a broadcasting system, commonly called a Public Address (PA) System or a pluralistic broadcasting system, refers to a system that transmits and controls broadcasts of various contents for each zone within a certain geographical range, such as a building or school. do.

The conventional public address system or multiplexed broadcasting system as described above applies power to the entire system (e.g., audio device, communication device, control device, etc.) to provide multiplexed broadcasting and priority broadcasting of the existing broadcasting equipment system, thereby reducing power consumption. There are many problems.

In addition, except for the open switch corresponding to the area or area where broadcasting is not performed, the remaining audio equipment is in a standby state, which causes power consumption, and equipment that is not normally used as audio broadcasting equipment is also turned off. There is a problem of consuming power by inputting it.

In addition, when controlling broadcast audio (e.g., volume, monitoring, amplification, etc.), there is a problem that power consumption is consumed by applying audio load to unused audio channels, and there is a problem that audio noise is amplified during multi-channel broadcasting. there is.
