In addition, terms and words used in the following description and claims should not be construed to be limited to ordinary or dictionary meanings, but are to be construed in a manner consistent with the technical idea of the present invention As well as the concept.

1 is a schematic diagram of a system 10 for managing all-channels broadcast channels according to an embodiment of the present invention.

The PSTN channel state management system 10 according to one embodiment may include an integrated control device 100, a plurality of channels 200, and a plurality of output devices 210. However, the public address broadcasting channel state management system 10 according to the present embodiment may further include other general-purpose devices.

The integrated control device 100 is a device for remotely controlling a plurality of output devices 300 located in various areas where audio output is broadcasted by a user of the public address channel state management system 10, . For example, the integrated control device 100 can control a plurality of output devices 300 installed in different broadcasting areas by being located in a broadcasting room.

The plurality of output apparatuses 300 may have the same configuration as a speaker for outputting audio output, and may be installed in different broadcast areas. For example, the plurality of output devices 300 may include an output device 211, an output device 212, and an output device 213 installed in each floor or each room of the building. The plurality of output devices 300 are connected to the plurality of channels 200 and the plurality of channels 200 are connected to the integrated control device 100 so that the plurality of output devices 300 are connected to the plurality of channels 200, And can receive audio output or the like from the integrated control device 100 through the control unit 100.

The plurality of channels 200 may represent the respective broadcast regions from which the audio output is output. One end of the plurality of channels 200 may be connected to the plurality of output devices 300 of the broadcasting area and the other end may be installed in advance in the broadcasting room for connection to the integrated control device 100.

The plurality of channels 200 and the plurality of output devices 300 can be located remotely from the integrated control device 100 and can be installed in the inside of the building or buried in the ground. It may be difficult to analyze and recover it. A method for monitoring a plurality of channels 200 and a plurality of output devices 300 by using an integrated control device 100 located at a remote location, Can be provided.

The integrated controller 100 may measure an initial line impedance for a plurality of channels 200 and set an initial state. The integrated control apparatus 100 may set an initial state for a plurality of channels 200 at the time of initial installation of the integrated control apparatus 100 or when an initial state setting request is received from an administrator.

The integrated controller 100 may measure the initial line impedance sequentially for a plurality of channels 200 and set different initial states for the respective channels 201, 202, and 203. The integrated controller 100 may output a predetermined reference signal to the plurality of channels 200 and measure the line impedance of the plurality of channels 200 to which a predetermined reference signal is output.

The initial state may represent the initial line impedance measured for the plurality of channels 200. [ In addition, the initial state may indicate whether or not each channel is used according to the measured initial line impedance. For example, if the measured initial line impedance for the first channel 201 is 10 OMEGA and the measured initial line impedance for the second channel 202 is 5 K OMEGA, Can be set to 10 OMEGA and the initial state of the second channel 202 can be set to 5 KM.

In addition, the integrated controller 100 may initially set the line to an unused state when the initial line impedance is a predetermined maximum reference value, for example, 5 K? Or more, according to the measured initial line impedance. That is, the integrated controller 100 may set the initial state of the first channel 201 to the use state and the initial state of the second channel 202 to the unused state.

The integrated control device 100 may receive a status check request for a plurality of channels 200. For example, the integrated control apparatus 100 may receive a status check request from an administrator or a status check request periodically generated at predetermined intervals.

The integrated controller 100 may measure the current line impedance for the plurality of channels 200 according to the status check request. The integrated controller 100 can measure the current line impedance in the same manner as the measurement of the initial line impedance.

The integrated controller 100 may determine the current state of the plurality of channels 200 according to the measured current line impedance based on the initial state set in advance. For example, the integrated controller 100 may determine the current state of each of the channels 201, 202, and 203 by comparing the initial line impedance of the plurality of channels 200 with the current line impedance.

The current state is state information indicating whether the plurality of channels 200 are operating normally or abnormally with respect to the plurality of the channels of the plurality of output devices 300, And may be status information including whether or not it is normal. For example, the current state is a preset state type and can be determined as any one of a normal state, a short-circuit state, a disconnection state, a fluctuation state, and a fault state.

The integrated controller 100 can determine only the current state of the channels corresponding to the use state among the plurality of channels 200 based on the initial state set in advance. That is, the integrated controller 100 can determine the current state of the channels corresponding to the use state by measuring only the current line impedance of the channels corresponding to the use state. The integrated control device 100 can reduce unnecessary operations and power by not judging the current state of the unused channels.

The integrated controller 100 may display the current status of the plurality of determined channels. The manager can grasp the current state of the plurality of channels 200 indicating different broadcasting areas at a glance through the integrated control device 100. [

In addition, the integrated controller 100 may determine channels to output audio output among the plurality of channels 200 according to the determined current state. For example, if it is determined that the current state of the channel 203 among the plurality of channels 200 is short-circuited, the integrated controller 100 may output the audio output except for the channel 203. The integrated controller 100 can prevent the output device 213 from being damaged by outputting the audio output to the channel 203 that is in the short-circuited state.

In addition, the integrated controller 100 may determine channels to output audio output among the plurality of channels according to the determined initial state. For example, the integrated control device 100 may output an audio output except for the channel 202 whose initial state is unused among the plurality of channels 200, thereby reducing unnecessary computation and power.

The integrated control apparatus 100 may output the audio output to the determined channel 201 among the plurality of channels 200 and the channel 201 may transmit the audio output to the output apparatus 211. [ The output device 211 can output the received audio output to broadcast. At this time, the administrator of the PSTN channel state management system 10 can quickly and accurately check which broadcasting area the broadcasting is normally through by displaying the current status of the channels 200. [

FIG. 2 shows a detailed configuration of the system for managing the overall broadcast channel status of FIG.

Referring to FIG. 2, the PFC channel state management system 10 includes an integrated controller 100, a plurality of channels 200, and a plurality of output devices 300, An initial state setting unit 120, a state determination unit 130, a user interface unit 140, a counter 150, an output control unit 170, and an audio input / output unit 170.

The integrated control device 100 is a device for remotely controlling a plurality of output devices 300 and a plurality of channels 200 connected thereto, which are located in various regions where audio output is broadcasted, and may be a mobile device. The integrated control device 100 may include a plurality of output devices 300 and various hardware and software configurations for controlling the plurality of channels 200. [ In FIG. 2, only the components shown in FIG. 2 will be described in order to prevent the features of the present embodiment from being blurred. It should be understood by those skilled in the art, however, that other general-purpose components other than the components shown in FIG. 2 may be included.

The measurement unit 110 may be configured to measure a line impedance of a plurality of channels 200 connected to the integrated controller 100.

Specifically, the measuring unit 110 may measure the line impedance of the plurality of channels 200 when the initial state setting request is received. At this time, the measured line impedance can be the initial line impedance. The measuring unit 110 may measure the initial line impedance sequentially for the plurality of channels 200. [ The measuring unit 110 may measure a line impedance of a plurality of channels 200 outputting a predetermined reference signal and outputting a predetermined reference signal to the plurality of channels 200.

In addition, the measuring unit 110 may measure the line impedance of the plurality of channels 200 when the status check request is received. At this time, the measured line impedance can be the current line impedance. The measuring unit 110 can measure the current line impedance in the same manner as the measurement of the initial line impedance.

The measuring unit 110 may measure only the current line impedance of the channels corresponding to the use state among the plurality of channels 200 based on the initial state set previously.

The measuring unit 110 may include a reference signal oscillator for generating a predetermined reference signal to be output to the plurality of channels 200. The measuring unit 110 may include a reference signal oscillator, And a 12-bit AD converter for receiving the feedback signal and converting it to line impedance.

The initial state setting unit 120 may set an initial state for a plurality of channels 200 using the initial line impedance measured by the measuring unit 110 when an initial state setting request is received.

The initial state may represent the initial line impedance measured for the plurality of channels 200. [ In addition, the initial state may indicate whether or not each channel is used according to the measured initial line impedance.

For example, when the initial line impedance measured for the first channel 201 is 10 OMEGA and the initial line impedance measured for the second channel 202 is 5 K OMEGA, the initial state setting unit 120 sets the initial channel impedance of the first channel 201 201 can be set to 10? And the initial state of the second channel 202 to 5?. Alternatively, the initial state setting unit 120 may set the initial state of the first channel 201 to the use state and the initial state of the second channel 202 to the unused state according to the measured initial line impedance.

The initial states of the plurality of channels 200 set by the initial state setting unit 120 may be transmitted to the state determining unit 130 or the output control unit 170 and may be stored in a storage unit (not shown).

The state determination unit 130 may be configured to check the current state of the plurality of channels 200. [ The state determiner 130 may determine the current state of the plurality of channels 200 using the current line impedance measured by the measuring unit 110, when the state check request is received.

The current state is state information indicating whether the plurality of channels 200 are operating normally or abnormally with respect to the plurality of the channels of the plurality of output devices 300, And may be status information including whether or not it is normal. For example, the current state is a preset state type and can be determined as any one of a normal state, a short-circuit state, a disconnection state, a fluctuation state, and a fault state.

The state determiner 130 may determine each of the current states of the plurality of channels 200 as one of the preset state types related to the current state.

Specifically, when the measured current line impedance is less than a predetermined minimum reference value, the state determiner 130 may determine the current state of the channel as a short state. For example, the predetermined minimum reference value may be 5?.

The state determiner 130 may determine that the current state of the channel is open if the measured current line impedance is greater than or equal to a predetermined maximum reference value. For example, the predetermined maximum reference value may be 5K [Omega].

The state determiner 130 may determine the current state of the plurality of channels 200 according to the current line impedance based on the initial state set in the initial state setting unit 120. [ For example, the state determiner 130 may determine the current state of each of the channels 201, 202, and 203 by comparing the initial line impedance of the plurality of channels 200 with the current line impedance.

For example, when the measured current line impedance is equal to the initial line impedance, the state determiner 130 may determine the current state of the channel as a normal state. The same impedance may include that the line impedance fluctuates (increases or decreases) within a predetermined variation range. For example, the predetermined range of variation may be 10%.

The state determiner 130 may determine the current state of the channel as a fluctuation state when the measured current line impedance is changed by 10% or more as compared with the initial line impedance. If the measured current line impedance is increased by 50% or more as compared with the initial line impedance, the state determination unit 130 determines that the output device connected to the corresponding channel has failed and sets the current state of the corresponding channel as a failure state It can be judged.

Upon receiving the status check request, the status determination unit 130 may determine only the current status of the channels corresponding to the usage status among the plurality of channels 200 based on the initial status.

The counter 150 may be configured to calculate time information to automatically and periodically manage the public address channel state management system 10. [

For example, the counter 150 may periodically monitor the current time to generate a status check request at each preset time. The counter 150 may generate a status check request when the current time matches a predetermined time.

The output controller 170 controls the overall operation of the integrated controller 100 to control the audio output of the plurality of channels 200.

The output controller 170 may determine the channels to output the audio output according to the initial setting and the determined current state set for the plurality of channels 200. [

For example, the output control unit 170 may determine the channels whose initial states are in the use state as channels to output the audio output.

In addition, the output controller 170 may determine to output the audio output to the channels other than the channel whose current state is short-circuited. The output control unit 170 may determine the channels whose current state is the normal state as the channels for outputting the audio output.

The integrated controller 100 can prevent an output device connected to the channel from being damaged by outputting an audio output to the channel in a short-circuited state.

In addition, the integrated controller 100 may determine channels to output audio output among the plurality of channels according to the determined initial state. For example, the integrated controller 100 may output an audio output except a channel whose initial state is unused among a plurality of channels 200, thereby reducing unnecessary computation and power.

The integrated control device 100 may output an audio output to a channel determined to output an audio output among a plurality of channels 200 and a channel receiving the audio output may transmit an audio output to an output device connected to the corresponding channel have.

The output device can output the received audio output to broadcast. At this time, the administrator of the PSTN channel state management system 10 can quickly and accurately check which broadcasting area is normally broadcasted by displaying the current status of the plurality of channels 200. [
