In general, an internal broadcasting system / public broadcasting system is a system designed to broadcast in a single building or a neighboring building such as an office building or a hotel in a desired area, a floor, and a district, and simultaneously transmits various sound sources It is designed to be able to select different sound sources according to each region or area, and it is designed to be variously modified according to the size and necessity of the building.

Among these public address broadcasting systems, in particular, a broadcasting system installed in a building or the like has a transmitting apparatus installed in a central broadcasting room, and a receiving apparatus is installed in each conference room. And broadcasts to each conference room in a central broadcasting room through a speaker or a television as a receiving apparatus.

However, in the case of the tree structure, the broadcasting system and the conventional broadcasting system having the general tree structure / ring structure as described above have a disadvantage in that the wiring work is complicated and the cost is increased because the wires are connected to the terminal equipment in a centralized manner. In case of the structure, there is a disadvantage that a collision detection protocol must be established in all equipment, and broadcasting can not be performed when the network is broken.

In addition, there is a problem in that a broadcast system of a general tree structure / ring structure and a conventional technology do not have a broadcast supplementary function for traffic of a network network and broadcasts are disconnected when traffic is excessive, .

Hereinafter, a network-based intelligent broadcasting system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a schematic block diagram of a tree structure network broadcasting system according to the present invention. In FIG. 3, a main controller 200 for controlling the overall operation of a broadcasting system and an administrator terminal 100 are connected via a network, (401 to 400n) are connected to a redundant network. Where the duplicated network may include first and second networks 301 and 302.

In addition, the main controller 200 and the first and second networks 301 and 302 may be wired or wirelessly connected, or wired or wirelessly connected. Especially, in the case of wireless connection, there is an advantage of solving the problem of the existing wiring installation. Here, the IP addresses of the first network 301 and the second network 302 are different from each other, and the network is switched using the IP address.

The tree structure network broadcasting system configured as described above is connected to the main controller 200 and each of the terminals (terminal A, terminal B, and terminal C) by using any one of the redundant first and second networks 301 and 302, Lt; / RTI > At this time, the main controller 200 monitors traffic for each network and performs traffic control based on the traffic monitoring result. For example, when the traffic of the specific network exceeds the predetermined reference value as a result of the traffic monitoring, some terminals may use the first network 301, some may distribute the networks to use the second network 302, Thereby preventing data loss and ensuring data transmission speed.

In addition, if a failure occurs in a specific network, the network is switched to another network so that broadcasting is continuously performed even when a failure occurs in a specific network. In addition, an automatic reset operation is performed for the failed network, and the network failure is automatically recovered. If the failure can not be recovered by the recovery operation, a message about the network failure is generated, and the message is sent to the administrator terminal to inform the administrator of the network failure. This allows administrators to be aware of network failures in real time while remotely located.

FIG. 4 is a schematic block diagram of a ring network broadcast system according to the present invention. In FIG. 4, a main controller 200 for controlling the entire operation of a broadcasting system and an administrator terminal 100 are connected via a network, (401 to 400n) are connected to a redundant network. At this time, the main controller 200 and the start terminal (for example, 401) and the end terminal (for example, 400n) of the plurality of terminals are connected to the redundant network 501 to 504, And are connected to the redundant networks 506 to 508.

The redundant network may include first and second networks 501 and 502. 4, the third network 503 and the fourth network 504 are actually the same networks as the first and second networks 501 and 502, and the fifth network 505 to the eighth network 508 And is actually the same network as the first and second networks 501 and 502. For convenience of explanation, the symbols are different from each other, and only the names are different.

The main controller 200 and the first and second networks 501, 502, 503 and 504 may be wired or wirelessly connected, or wired or wirelessly connected. Especially, in the case of wireless connection, there is an advantage of solving the problem of the existing wiring installation.

Likewise, each terminal can be connected by wire or wirelessly, or by wired or wireless connection. Especially, in the case of wireless connection, there is an advantage of solving the problem of the existing wiring installation.

When the communication system is implemented using the ring network as described above, since the wires are quadrupled between the main controller 200 and the terminals, more stability can be achieved in broadcasting.

The ring network broadcast system configured as described above is connected to the main controller 200 and some terminals (for example, the first and second networks 501, 502, 503, and 504) Terminal A, terminal C) are connected. At this time, the main controller 200 monitors traffic for each network and performs traffic control based on the traffic monitoring result. For example, when the traffic of the specific network exceeds the predetermined reference value as a result of the traffic monitoring, some terminals may use the first network 301, some may distribute the networks to use the second network 302, Thereby preventing data loss and ensuring data transmission speed.

Similarly, each terminal is connected to each other through a redundant network. If a failure occurs in a connected network, the terminal immediately switches to another network through network switching. It is preferable to switch the network using the IP address.

In addition, if a failure occurs in a specific network, the network is switched to another network so that broadcasting is continuously performed even when a failure occurs in a specific network. In addition, an automatic reset operation is performed for the failed network, and the network failure is automatically recovered. If the failure can not be recovered by the recovery operation, a message about the network failure is generated, and the message is sent to the administrator terminal to inform the administrator of the network failure. This allows administrators to be aware of network failures in real time while remotely located.

FIG. 5 is a block diagram of a network-based intelligent broadcasting system according to a preferred embodiment of the present invention. Referring to FIG. 5, terminals 401 to 400n, an administrator terminal 100, a main controller 200, ) ≪ / RTI >

Herein, the first network 301 and the second network 302 are symbols of a tree structure. When the first network 301 and the second network 302 are implemented as a ring structure, the first network 301 and the second network 302 are changed to the first network 501 and the second network 502, respectively. Hereinafter, the first network 301 and the second network 302 will be described for convenience of explanation. The tree structure and the ring structure network have been described in detail with reference to FIG. 3 and FIG. 4, and a detailed description of the tree structure and the ring structure network will be omitted below in order to avoid redundant description.

The terminals 401 to 400n serve to output a broadcast signal, which means an amplifier and a remote amplifier.

The main controller 200 is connected to the terminals 401 to 400n through a redundant network. The main controller 200 controls the network switching by determining the used network through the redundant network traffic monitoring, It performs the automatic recovery of the faulty network.

The duplexed network includes first and second networks 301 and 302 and the terminals 401 to 400n and the main controller 200 are connected to the first and second networks 301 and 302, It is preferable to be connected through any one of them.

The main controller (200) includes a network interface (201) for interfacing data with the terminal through the duplicated network; A traffic monitoring unit 202 for monitoring traffic of a redundant network connected through the network interface 201; A network determination unit (203) for determining a network to be connected to each terminal according to a traffic monitoring result of the traffic monitoring unit (202); A network switching unit 204 for switching to a network to be used among the redundant networks under the control of the network determining unit 203; A network communication state detection unit 205 for detecting a communication state of the redundant network connected through the network interface unit 201 and transmitting the detected state to the network determination unit 203; A faulty network automatic reset unit 206 for automatically resetting the faulty network and performing automatic recovery when a fault occurs in the random network as a result of detecting the network in the network communication state detection unit 205 and the network communication state detection unit And a network failure notification unit 207 for reporting network failure information, network information, and traffic monitoring result information detected by the network failure notification unit 205 to the associated administrator terminals.

The operation of the network-based intelligent broadcasting system according to the preferred embodiment of the present invention will now be described in detail.

The network interface 201 is connected to the first network 301 and the second network 302 to interface data between the main controller 200 and the terminals 401 to 400n. At this time, the traffic monitoring unit 202 is connected to the network interface 201 and monitors the traffic of the network in real time. Here, the traffic monitoring may include various methods, but it may include the number of channels occupied through the network and the data transmission rate of the corresponding channel.

The monitored traffic monitoring result information is transmitted to the network determining unit 203, and the network determining unit 203 determines network switching based on the traffic monitoring result information. That is, the network traffic state is determined based on the number of occupied channels of the network, the data transmission rate, and the like, and the network switching is determined based on the determined state. For example, if the traffic is overheated only in a specific network, the data transmission rate is slow, and data transmission / reception with the terminal that can not occupy the channel or data transmission / reception between the terminals can not be performed. Accordingly, in order to solve this problem, the present invention determines a network to be used or a network to be switched based on the traffic result monitored by the network determining unit 203. In this case, the network determination method determines the network to use the presently used network when the traffic of the network is appropriate, and determines the network change to the network that is not overheated if the specific network is overheated.

The network switching unit 204 switches the network according to the network determination. That is, it connects a network between a terminal and a main controller or between a terminal and a terminal.

In another aspect of the present invention, it is possible to detect a network communication state and perform network switching while automatically attempting a failure recovery.

For example, the network communication state detection unit 205 is connected to the network interface 201 to detect a communication state of the network. That is, it senses a communication signal of a specific network, detects whether a communication signal normally occurs, and detects a communication state. The communication state detection result is transmitted to the network determination unit 203 and the faulty network automatic reset unit 206, respectively.

The network determination unit 203 analyzes a communication state detection signal to determine a network communication state. For example, if the communication status detection signal is analyzed and the network communication status signal is not generated at all, or the detection period of the detection signal is long, or the network communication status signal is very weak, it is determined that a failure has occurred in the network, The switching unit 204 controls the network switching so as to use another network instead of the failed network.

In addition, the failure network automatic reset unit 206 also analyzes the communication status detection signal to determine the network communication status. For example, if the communication status detection signal is analyzed and the network communication status signal is not generated at all, or the detection period of the detection signal is long, or if the network communication status signal is very weak, it is determined that a failure has occurred in the network. If it is determined that the network has failed, the network is automatically reset. After performing the network automatic reset, the communication status detection unit 205 analyzes the communication status detection signal generated by the network communication status detection unit 205 to determine whether the network failure has been eliminated. If the network failure is not resolved, the network automatic reset is performed again. It is preferable that the automatic network reset process is performed a predetermined number of times only when the network failure has not been solved.

It is an advantage of the present invention to perform an A / S function that can automatically recover a faulty network by automatically resetting a faulty network while continuously broadcasting while switching to a spare network at the time of a network network breakage have. Therefore, it is impossible to broadcast in case of a network failure, and the inconvenience of a service person performing a manual reset can be solved. Especially, in case of a network failure, it takes a long time for a service person to manually check the network, and broadcasting can be stopped until a failure is recovered, which can cause a serious problem. However, the present invention can minimize the network failure recovery time through the network automatic reset function.

In addition, when a network failure occurs, the network communication status detection unit 205 notifies the network failure notification unit 207 of the failure.

The network failure notification unit 205 generates a text message for the network failure and transmits the text message to the previously registered administrator terminal 100 through the network so that the remotely located administrator can recognize the network status in real time. In addition, when the failure is recovered, the failure recovery data can be generated and transmitted to the administrator terminal 100, and it is possible to transmit the traffic monitoring result to the administrator terminal 100 as needed.

Therefore, the administrator does not have to continuously check the network of the broadcasting system manually, and can recognize the state of the network in real time even if the user is far from the broadcasting system.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
