Description

Network-based digital public control public address system {Network-based digital Public Adress system}

The present invention relates to a public address broadcasting system, and more particularly, to compress / restore sound and convert it into a protocol suitable for a network, to install a Linux-based OS, and to control various sound devices. By connecting a computer via LAN or the Internet to a multimedia server that can receive firefighting data, the public address can be broadcast without limiting the location, and in the event of an emergency such as a fire, all remote locations can be monitored and controlled centrally. The present invention relates to a network-based digital remote control public address system.

The conventional public address broadcasting facility has limited limitation in interworking operation with IBS system by using analog transmission of voice signal of analog type by transmitting analog signal network as electric signal type or by using modulation method for modem transmission. There was a problem in the complex operation between the main equipment and the local equipment, so when the main equipment had an error, it was not smooth.

In addition, large companies with nationwide production bases or international production lineups had to cope with local fire situations locally, which made it difficult to proactively cope with the occurrence of fire. In the case of broadcasting, there was a problem in that the effect of Japanese broadcasting was halved because of re-broadcasting individually after the verbal instructions on the fax or telephone.

An object of the present invention for solving the problems as described above is to compress / restore the sound and convert it to a protocol suitable for the network, and equipped with a Linux-based OS, COM PORT communication for the control of various audio devices is possible The public address system can be made without limitation of location by configuring a public address system using a multimedia server including a serial port for receiving fire protection data of disaster prevention equipment and a computer connected to the multimedia server through a LAN or the Internet. In addition, to provide a network-based digital remote control public address system that can monitor and control the status of all remote locations from the center in the event of an emergency such as a fire.

An embodiment of the present invention for achieving the object as described above looks at with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a network-based digital public address broadcasting system according to the present invention, Figure 2a is a block diagram showing an example of building application of public address broadcasting system according to the present invention, Figure 2b is a public hall according to the present invention It is a block diagram which shows the example of factory application of a broadcasting system.

An electric network-based digital remote control public address broadcasting system according to the present invention includes an electric microphone including a microphone 12, a speaker 14, a sound source generator 16 such as a cassette deck or a CD player, and a fire receiver or disaster prevention equipment 18. In the broadcasting system, the microphone 12 and the speaker 14 and the fire receiver or disaster prevention equipment 18 and the like are connected by a communication protocol such as RS-232, RS-485, the microphone 12 and the speaker 14 COM PORT communication is possible for the operation control, and includes a serial port for receiving the fire protection data of the disaster prevention equipment 18, converts and transmits the signals output from these devices to a protocol bonded to the network, the microphone ( 12) and a multimedia server 20 for outputting an operation control signal to the speaker 14, and a microphone 12, and connected to the multimedia server 20 through a communication network such as a LAN or the Internet and undergoes user authentication. After various The selection of the operational modes of the tube broadcast system consists of a system manager 30 which outputs the audio signal to the operation control signal, and the corresponding broadcast.

In addition, by applying static IP, it can be used as an address on the network, and it is a network device that makes various functions such as control of various devices and sound selection by making and applying homepage to the device itself.

And, by using a web browser for the Internet, it is possible to overcome the spatial constraints of the user who wants to broadcast, and it is possible to build a DB using the memory of the equipment itself, so that the time of broadcasting occurrence, alarm occurrence time, and end time can be saved. Not only can this be possible, the report can be printed out, and real-time monitoring is possible through user authentication from any PC on the same network.

The multimedia server 20 accepts one of the LINE inputs output through the PRE AMP or the AUDIO MIXER 22, and these sound source supply devices are servers 20 if they are capable of RS-232 or RS-485 communication. ) Can be controlled by operating a separate CONTROL program and a communication converter (not shown) is used for communication between the server 20 and the sound source equipment.

In order to operate with the fire receiving panel or disaster prevention equipment 18 which is the most important function of public address broadcasting equipment, the multimedia server 20 is a relay board or a multi-channel COM PORT BOARD capable of RS-232 communication for taking contact input. Use

In order to receive a fire signal and to operate an emergency broadcast, a separate PAGE VIEW is provided in the HOME PAGE built in the server 20 so as to set the name of each input point and the operation mode related to the broadcast operation when the fire signal is input.

In addition, the server 20 stores various voice data related to the alarm broadcast in the form of a wave file to enable appropriate voice warning broadcast as required. In case of a specific emergency signal, a practical operator wired / wireless telephone is used. Enable warning broadcasts directly.

For the announcement function, one of the main functions of public address broadcasting equipment, general broadcasting is possible using its own MIC input part, and the setting of broadcasting area can be performed by manual selection and automatic selection by incorporating SPEAKER SELECTOR in itself. Do it. This broadcasting is operated at the place where the server 20 is installed, but the manager system (PC) at any place where the administrator can operate can access the web and select a broadcasting area to select a microphone (not shown) provided in the PC. Broadcasting is possible. At this time, the control of the speaker selector is possible on the web.

As can be seen from the above, in the application and operation of the PA system according to the present invention, a complex operation of a conventional broadcast (main broadcasting in LOCAL SIGHT), monitoring of the status of the broadcasting equipment of the manager, and various forms are possible. Management of broadcasting equipment, compensation for the increase of facility cost due to civil works and plumbing / wiring work due to installation of equipment in large spaces such as factories, and guarantee of convenience according to the maintenance and management of equipment. It can increase efficiency.
