Description

Broadcasting audio system monitoring system and control method thereof

The present invention relates to a broadcast system, and more particularly, to a monitoring system of a broadcast audio system and a control method thereof.

Currently, the broadcasting system lacks an alarm function in the event of a failure, and most of the operations are monitored by the operator.

In the case of the audio transmission system, since the sound output from the first to the last output stage is the same, it is judged whether there is an abnormality by listening to the final stage output.

Not only unintended radio transmission interruption status (static wave), but also a non-modulated state by silence in which no signal is carried on the radio wave should be prevented. To achieve this goal, an independent silent sensor is installed and used as an auxiliary monitoring tool.

In the case of broadcasting, the sound source may remain silent for a certain period of time, so a short unmodulated state may be normal, but if a certain period of time persists, appropriate measures should be taken. This unmodulated state is caused by mistakes or mechanical failures in broadcast production transmission operation.

Currently, the criterion of the broadcasting accident according to the embodiment is set to 6 seconds or more in the non-modulation duration, and when an abnormality of such a transmission system occurs, the operator must determine which part of the transmission system is abnormal by intuition.

In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

1 is a block diagram of a monitoring system for a broadcast audio system according to an embodiment of the present invention.

Referring to Figure 1, the monitoring system of the broadcast audio system according to an embodiment of the present invention,

The audio equipment 11 to 15, the switches 21 and 22, the audio processing units 30 and 40, the output stage detecting unit 60, the control unit 70, the display unit 80, and the alarm unit 90 are included.

The audio equipments 11 to 15 provide audio signals of various sound sources received or received from a broadcasting station of a broadcasting station, and can be added, deleted, and modified as necessary, and replaced in the event of any audio equipment failure. The ranking can also be modified.

In the embodiment of the present invention, the priority is determined in the order of LINE 11, STL1 12, STL2 13, SNG 14, and standard FM 15.

The above terms are given arbitrarily and may be given different names.

In addition, the switches 21 and 22 switch the audio signals output from the five audio equipments 11 to 15 to the processors 31 and 41 according to the control signal of the controller 70, and the operator can directly operate the audio signals. Alternatively, the switch 22 also switches the audio signal to the processor 51 as needed. The processor 51 used as spare equipment may be omitted in some cases, and may be output to the transmitter through any wiring through the audio patch panel.

The audio processors 31, 41, and 51 process the audio signal of each line so as to be a signal suitable for transmission. The processed audio signal is transmitted through a transmitter 32, 33, 42, 43 to a receiver such as a radio or another transmitting station, a relay station, or the like.

On the other hand, the output stage detection unit 60 detects and outputs the output signal of each audio equipment 11 to 15, the output signal of the switches 21 and 22, and the output signal of the processors 31 and 41.

The control unit 70 receives a signal received from the output end detection unit 60 and determines whether or not each received signal is silently modulated, and checks whether there is an abnormality. To show.

The display unit 80 displays the presence or absence of an abnormality in a graphic screen according to the signal of the controller, and displays the audio signal level state with a level meter and a phase monitor together with the system schematic diagram.

Referring to the operation of the monitoring system of the broadcast audio system according to an embodiment of the present invention having such a configuration in detail as follows.

2 is an operation flowchart of a monitoring system of a broadcast audio system according to an exemplary embodiment of the present invention.

First, a sound source selected from various audio signals of the audio equipment 11 to 15 is output through the switches 21 and 22 under the control of the controller 70.

The analog or digital audio signals of the respective audio equipments 11 to 15 are processed by the audio processors 31, 41, and 51 and transmitted through a transmitter selected from the transmitters 32, 33, 42, and 43. The radio waves are then received through the antenna so that the listener can listen.

On the other hand, the output stage detection unit 60 detects and outputs the output signal of each audio equipment (11 ~ 15), the output signal of the switches (21, 22), the output signal of the processor (31, 41) (S210). At this time, the controller 70 measures the Vrms value of the audio signal in real time in order to detect the signal of each output terminal. The measured Vrms value is processed so that it can be displayed as a VU meter where 0.775 (Vrms) becomes 0 (dBu). In particular, it processes so that it can be displayed by the phase monitor which is a function for monitoring the left and right channel phase of a stereo broadcast.

In addition, after the predetermined procedure, the control unit 70 displays the processed result on the screen of the display unit 80 in real time (S270).

At this time, the controller 70 immediately calculates the elapsed time in units of 0.01 seconds when the Vrms value (dBu value) measured for the non-modulation test is equal to or less than a predetermined value. Then, the control unit 70 resets the elapsed time to 0.0 seconds when the measured value becomes a predetermined value or more (S220).

Next, the control unit 70 determines the unmodulated elapsed time for each output terminal (S230, S231), and when it is 6.0 seconds or more (S231), the control unit 70 determines that the alarm condition causes the alarm unit 90 to generate an alarm (S270).

In addition, the control unit 70 compares the unmodulated elapsed time for the five points which are the outputs of the corresponding audio equipments 11 to 15 in the main backup system configuration (S240, S241), and if there is a difference in the elapsed time, It is determined that there is a (S241), to be an alarm (S270). In this case, switch control is performed according to a predetermined priority (S260). By controlling the switch according to this predetermined priority, it is possible to quickly cope with the failure of the audio equipment.

Next, the process of determining whether there is an abnormality (S231, S241) by using the sensed signals input by the controller 70 in the above process will be described in detail with reference to FIGS. 3A to 3E.

3A to 3E, first, when the unmodulated (silent) elapsed time values for five points that are outputs of the audio equipment 11 to 15 are N1, N2, N3, N4, and N5, respectively, In the silent state, the values of N1, N2, N3, N4, and N5 will be the same, so an alarm will sound when 6 seconds elapse, but in this case, the path change control is unnecessary, and the cause of the sound source being silent should be identified.

In the case of FIG. 3A, there is an abnormality, and in this case, switching to the high priority audio equipment is shown in FIGS. 3B to 3E.

As an example, the audio equipments 11 to 15 of FIGS. 3A to 3E are configured for main backup, and the same audio may be output except for different paths transmitted from the performance station. If one path or the corresponding equipment is broken, the value of the broken part of N1 to N5 is a silent condition, so the unmodulated elapsed time increases, and the remaining non-failure is increased when the sound source is silent, and 0 is not. Be sure to

Therefore, when the controller 70 knows the equipment currently selected as the signal output and the no-transmission time corresponding to the signal is N1, N1-N2 representing the difference between the N2 value and the N5 value corresponding to the other remaining signals. If it is determined that there is an abnormality within 1 to 6 seconds using the absolute values for the values N1 to N5, the alarm unit 90 causes an alarm to be displayed, and a failure point is displayed on the display unit 80.

If the output of the audio equipment (11 to 15) according to an arbitrary signal path at the time of the alarm is broken (S240, S241), the control unit 70 connects the input terminals of the switch unit (21, 22) to the audio equipment according to the priority If the switch 21 or 22 or the processor 31 or 41 is faulty, the controller 70 causes the output of the normal system to be output through the transmitter.

As described above, the controller 70 may compare the main corresponding points of the main and backup paths constituting multiple systems to ensure the stability of the broadcast as described above (S240), and the signal starting from the audio equipment 11-15. It is also possible to compare the presence or absence of anomalies in the sequential direction (S250).

In this case, even when the switch control (S260) is not accompanied, the broadcast accident (no modulation) according to the equipment failure can be detected at a time earlier than 6 seconds according to the embodiment by comparing the unmodulated elapsed time (S241). ). In addition, since such a state is represented by a graphic screen as shown in FIG. 4, a worker may quickly take action by intuitive situation determination when an accident occurs.

In the process, if the alarm sound continues to sound while the alarm is in the alarm state, the operator may cause inconvenience in identifying and recovering the cause of the problem. Meanwhile, an alarm sound may also occur during the maintenance of the device. In order to alleviate the inconvenience caused by the alarm sound, an alarm sound ON / OFF function is provided so that the alarm sound is not output. The broadcasting system operator must turn on the function so that the alarm sound can be generated externally after recovering the system. However, in some cases, the alarm sound switch is left in the OFF state, so that it may not be possible to respond quickly to a problem. In order to overcome this, an embodiment of the present invention uses the following method.

According to the exemplary embodiment of the present invention, an alarm sound is generated by a lamp, a buzzer, or a speaker of the alarm unit 90 according to a problem occurrence, or an alarm display is performed by a graphic screen of the display unit 80. The purpose is to inform the operator, which allows the operator to determine the cause of the problem. However, if the alarm sound continues to sound during the process of restoring the system, the user may feel inconvenient. Accordingly, the operator operates the control unit 70 to turn on / off the alarm unit 90 so as to turn on / off the output of the alarm sound. Controls off

When a problem occurs and the operator recovers the problem with the alarm sound output turned off, the operator must recover the alarm sound output to the on state where possible, but may forget it. In this case, there is a possibility that a problem may not be quickly recognized because an alarm sound is not output when a problem occurs later.

In order to prevent this problem in advance, it is possible to automatically return to a state where the alarm sound can be output in a foolproof manner. The alarm sound is determined as shown in the table of FIG.

In addition, the operator turns off the alarm output before proceeding with the maintenance work of the system and proceeds with the work.The system turns off the alarm output in the normal state (alarm status fall) and the alarm state is cleared by the maintenance work. Alarm output is maintained and no alarm sound is generated. Therefore, the control unit 70 of the embodiment of the present invention returns to the alarm sound output on state when the maintenance work is completed and the alarm state becomes a false.

For example, an alarm state may be true and a normal state may be called a false. At this time, if the system is in a normal state, the alarm state is maintained in a false state. In case of a Tour in the Fall state, when the user turns off the alarm sound while the alarm is generated, the alarm sound is not generated. When the problem is recovered and the alarm state is false, that is, when the alarm state changes from true to false, the problem is solved. If the alarm sound is off, the state should be turned on.

If the operator has turned off the alarm sound when the alarm condition is in the false state (no alarm sound), then it is time to start work to maintain the system. Once you start maintenance work, the alarm condition can go from false to true. In this case, no alarm sounds. When the maintenance work is completed and the system is normal, the alarm state is false in the true state, and in this case, the control unit 70 causes the alarm sound to be automatically turned on. In other words, when the alarm state is set to false in the true state, the alarm sound generation must be returned to on, so that the alarm tone may sound when the alarm state is changed from false to true. In addition, when the alarm state maintains the true state or the false state, the control unit 70 allows the alarm sound generating function to be maintained in an on or off state selected by the user. In addition, the alarm sound may be returned to ON after 10 seconds as an example so that the generation of the alarm sound does not remain OFF for a long time while the alarm state is false.

A summary of the flow of such contents is shown in FIG. 6.

Referring to FIG. 6, after an alarm is displayed according to an alarm signal, an alarm sound may or may not be generated according to an alarm on / off.

At this time, when the operator device check is completed, the user turns off the alarm, but the controller 70 turns on the acoustic alarm.

On the other hand, the control unit 70 may detect the output stage of the multiple points in which the audio is transmitted (S250), and find the abnormal occurrence point based on the detected result (S251). Since audio is transmitted sequentially, after the point where the abnormality occurs, the state is unmodulated. Therefore, it is assumed that no modulation problem occurs at the most advanced point.

Here, since the silent modulation states are determined for each stage (S231 and S241), all of the silent modulation states are displayed on the display unit 80 (S270). In addition, the point estimated through the abnormal occurrence point determination (S251) is additionally displayed in a special form (S270). For example, a special shape is like a blink that periodically changes color.

The alarm unit of the above process can be applied not only to the broadcast audio system but also to a video system or a remote control surveillance field, and the detailed description is omitted since such an application can be easily implemented by those skilled in the art.

This allows the operator to restore the device in a short time, and during the recovery period, the broadcast is made through a normal path. 4 illustrates an embodiment of a system diagram and a monitoring screen according to an embodiment of the present invention, which may be variously modified as necessary.

Such embodiments of the present invention may be variously modified, and a separate monitoring system may be constructed for each transmission station. In addition, since the audio transmission system is separately processed in TV broadcasting, it can be applied as it is. In addition, the function to display an alarm or a display part, or to control the switch of a fault system etc. can be used separately or together as needed.

In the above embodiment of the present invention, the control unit 70, the display unit 80, the alarm unit 90 may be configured to the outside as needed to enable remote control.

In addition, the controller 70 may be left as it is, and the display unit 80 and the alarm unit 90 may be configured externally to enable remote control. In this case, for example, the control unit 70 transmits a signal received from the output terminal detecting unit 60 to the display unit 80 and the alarm unit 90 which are located at a third place externally to display and alarm the signal. can do. A communication network configured for remote control of a broadcasting system generally uses a leased line with low bandwidth due to cost and security. In this case, if only the signals of True (Alarm) and False (Normal) are sent to each part of the monitoring system through the dedicated line, there is no problem in case of normality on the receiving side. The sound signal may be displayed in real time on the level meter as shown in the embodiment of FIG. 4, and in the case of true, the level meter information may not be displayed because it is silent.

The embodiment of the present invention described in the above process can be applied to not only a transmitting station but also a performance station, a head office system, or other third places, and can be variously modified as necessary.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit and scope of the present invention.
