A plurality of button images 60 imitate a plurality of actual buttons installed in a main control room, each of the button images 60 is linked to the actual button, and the actual lighting state of the button is reflected in the linked button image 60 in real time. Aside from this, the plurality of button images 60 may include images of buttons that are not actually installed in the main control room. An area in which a plurality of button images 60 are arranged can be clicked from the remote terminal 12, and when the area is operated, an enlarged button operation screen 50D (see FIGS. 5 and 6), which will be described later, is displayed on the remote terminal 12. The incoming call display element 62 simulates an actual telephone installed in the main control room in this embodiment, and visually notifies that the telephone in the main control room is receiving an incoming call. The incoming call display element 62 can be clicked or otherwise operated from the remote terminal 12, and although the details will be described later, by operating the incoming call display element 62, call start operation and call end operation are possible.

The main monitoring screen 50A is displayed on the remote terminal 12 as follows. That is, each PC operation screen is input from the plurality of system devices 46A to the operation switching unit 26, and the PC operation screen selected by the operation switching unit 26 under the control of the control unit 28 is input to the video synthesizing unit 22. Further, each video monitor screen and audio are input from the plurality of system devices 46B to the video switching unit 20 and the video synthesizing unit 22, and the video monitor screen and audio selected by the video switching unit 20 under the control of the control unit 28 are also input to the video synthesizing unit 22. Furthermore, the base image of the main monitoring screen 50A including the respective display units 52, 54, 56, 58, a plurality of button images 60, and an incoming call display element 62 is input from the operation unit 16 to the image synthesizing unit 22. FIG. Then, the image synthesizing unit 22 synthesizes the input image monitor screen on the composite monitor display unit 52 of the base image of the input main monitoring screen 50A and the individual monitor display unit 54, and synthesizes the waveform monitor of the image monitor screen synthesized on the individual monitor display unit 54 on the waveform display unit 56. Further, the video synthesizing unit 22 synthesizes the input PC operation screen with the operation screen display unit 58 of the base video of the main monitoring screen 50A to generate the main monitoring screen 50A.

After that, the video synthesizing unit 22 outputs the generated main monitoring screen 50A to the operation switching unit 26 together with the sound associated with the video monitor screen synthesized on the individual monitor display unit 54 . The operation switching unit 26 outputs the main monitoring screen 50A and the audio received from the video synthesizing unit 22 to the remote terminal 12B inside the office and to the remote terminal 12A outside the office via the remote unit 14 . In each of the remote terminals 12A and 12B, the main monitoring screen 50A is displayed on the monitor, and the audio of the video monitor screen displayed on the individual monitor display section 54 of the main monitoring screen 50A is output from the speaker.

Next, referring to FIG. 3, an example of a video monitor enlarged screen 50B is shown, and this video monitor enlarged screen 50B presents an enlarged image monitor screen displayed on the individual monitor display section 54 of the main monitoring screen 50A. The video monitor enlarged screen 50B includes an enlarged individual monitor display section 70, an enlarged waveform display section 72, and an operation screen display section 74. FIG. The enlarged individual monitor display portion 70 and the enlarged waveform display portion 72 are enlarged versions of the individual monitor display portion 54 and the waveform display portion 56 of the main monitoring screen 50A, and the operation screen display portion 74 displays a PC operation screen for switching the video monitor screen displayed on the enlarged individual monitor display portion 70. For this reason, the operation screen display unit 74 can be clicked from the remote terminal 12, and the video monitor screen displayed on the enlarged individual monitor display unit 70 can be switched according to the operation contents of the operation screen display unit 74.例文帳に追加In conjunction with the switching of the enlarged individual monitor display section 70, the video on the individual monitor installed in the main control room is also switched. While the video monitor enlarged screen 50B is being displayed, the audio associated with the video monitor screen displayed by the enlarged individual monitor display section 70 is output.

The video monitor enlarged screen 50B is displayed on the remote terminal 12 as follows. That is, in a state where the main monitoring screen 50A is displayed on the remote terminal 12, when the individual monitor display unit 54 of the main monitoring screen 50A is operated from the remote terminal 12, the operation switching unit 26 transmits the operation to the operation unit 16 as an operation targeting the operation unit 16. The operation unit 16 that has received this requests the control unit 28 to perform layout change control in order to generate the image monitor enlarged screen 50B. Upon receiving this request, the control unit 28 performs layout change control to cause the image synthesizing unit 22 to generate the enlarged image monitor screen 50B. The video synthesizing unit 22 synthesizes the same video monitor screen and waveform monitor displayed on the individual monitor installed in the main control room among the video monitor screens and waveform monitors input from the plurality of system devices 46B to the enlarged individual monitor display part 70 and the enlarged waveform display part 72 of the video monitor enlarged screen 50B provided from the operation unit 16. Further, the image synthesizing unit 22 synthesizes the PC operation screen for switching the image monitor screen provided from the system device 46A with the operation screen display unit 74 of the base image of the image monitor enlarged screen 50B to generate the image monitor enlarged screen 50B.

After that, the video synthesizing unit 22 outputs the generated video monitor enlarged screen 50B to the operation switching unit 26 together with the sound associated with the video monitor screen synthesized on the enlarged individual monitor display unit 70 . Thereafter, as in the case of the main monitoring screen 50A, the operation switching unit 26 transmits the video monitor enlarged screen 50B and the audio to each of the remote terminals 12A and 12B, the video monitor enlarged screen 50B is displayed on the remote terminals 12A and 12B, and the audio of the video monitor screen displayed on the enlarged individual monitor display unit 70 is output. Furthermore, when the PC operation screen of the operation screen display section 74 of the image monitor enlarged screen 50B is operated, it is transmitted to the system equipment 46A via the operation switching section 26, and the image monitor screen displayed on the individual monitor installed in the main control room is switched. Then, in conjunction with this, the image synthesizing unit 22 switches the image monitor screen synthesized on the enlarged individual monitor display unit 70 to the same image monitor screen as the individual monitor in the main control room. Further, in conjunction with this, the waveform monitor displayed on the expanded waveform display section 72 and the output sound are switched. In this manner, switching of the video monitor screen displayed on the enlarged individual monitor display section 70 is realized.

Next, FIG. 4 illustrates a PC operation enlarged screen 50C for enlarging and operating the PC operation screen, and this PC operation enlarged screen 50C includes an operation screen display section 78 and an icon display section 80. The operation screen display unit 78 is an enlarged version of various PC operation screens, and can be clicked from the remote terminal 12 . The icon display section 80 displays a plurality of icons for switching the PC operation screen to be displayed on the operation screen display section 78 and a "BACK" icon for returning to the main monitoring screen 50A. Therefore, each of these icons can be clicked or otherwise operated from the remote terminal 12, and the PC operation screen displayed on the operation screen display unit 78 or the monitor screen 50 itself is switched by the operation of each icon.

The enlarged PC operation screen 50C is displayed on the remote terminal 12 as follows. That is, when the operation screen display unit 58 of the main monitoring screen 50A is operated from the remote terminal 12 while the main monitoring screen 50A is displayed on the remote terminal 12, the operation switching unit 26 transmits the operation to the operation unit 16 as an operation targeting the operation unit 16. The operation unit 16 that has received this requests the control unit 28 to perform layout change control in order to generate the enlarged PC operation screen 50C. Upon receiving this request, the control unit 28 performs layout change control to cause the video synthesizing unit 22 to generate the enlarged PC operation screen 50C. The image synthesizing unit 22 synthesizes the PC operation screen input from the plurality of system devices 46A with the operation screen display unit 78 of the base image of the enlarged PC operation screen 50C provided from the operation unit 16 to generate the enlarged PC operation screen 50C. After that, the video synthesizing unit 22 outputs the generated PC operation enlarged screen 50C to the operation switching unit 26, and the operation switching unit 26 transmits the PC operation enlarged screen 50C received from the video synthesizing unit 22 to each of the remote terminals 12A and 12B. Then, the PC operation enlarged screen 50C is displayed on the monitor of each of the remote terminals 12A and 12B.

Further, when the operation screen display portion 78 of the enlarged PC operation screen 50C is operated, the operation is transmitted from the operation switching portion 26 to the system device 46A providing the PC operation screen displayed on the operation screen display portion 78. As a result, the operation of the system device 46A providing the PC operation screen displayed on the operation screen display section 78 is realized. Further, when each icon of the icon display unit 80 is operated, it is recognized by the operation unit 16, and under the control of the control unit 28, the PC operation screen selected by the operation switching unit 26 and synthesized on the operation screen display unit 78 by the image synthesizing unit 22 is switched. In this manner, switching of the PC operation screen displayed on the operation screen display unit 78 is realized. Alternatively, when the "BACK" icon is operated, it is recognized by the operation unit 16, and the main monitoring screen 50A is generated and displayed on the remote terminal 12 as described with reference to FIG.

Next, referring to FIG. 5, an example of an enlargement button operation screen 50D is shown, and this enlargement button operation screen 50D is for enlarging and operating a plurality of button images 60 displayed on the main monitoring screen 50A. A plurality of enlargement button images 84 and a screen display section 88 are included in the enlargement button operation screen 50D. A plurality of enlarged button images 84 are obtained by enlarging a plurality of button images 60 of the main monitoring screen 50A, and those simulating actual buttons installed in the main control room are enlarged while maintaining the linkage with the buttons. The screen display unit 88 is for displaying the image monitor screen and the PC operation screen individually or in combination without interlocking with any monitor installed in the main control room. In the enlargement button operation screen 50D of FIG. 5, a plurality of enlargement button images 84 are displayed in two rows at the top and bottom. On the other hand, the plurality of magnified button images 84 in the lower row may include, in addition to magnified buttons simulating the buttons actually installed in the main control room, operation buttons 90 to which functions different from those of the buttons installed in the main control room can be assigned.

Each of the plurality of enlargement button images 84 can be clicked from the remote terminal 12 , and each function assigned to each enlargement button image 84 is executed by operating each enlargement button image 84 . That is, when an enlarged button image 84 imitating a button actually installed in the main control room is operated, the function of the actual button is executed, and when the enlarged button image 84 corresponding to the operation button 90 is operated, an operation assigned in advance to the operation button 90 is executed. Further, when the enlarged button image 84 corresponding to the monitor switching button image 86 is operated, the video monitor screen displayed on the screen display section 88 is switched. Furthermore, when a video monitor screen is displayed on the screen display unit 88, the audio associated with the video monitor screen is output. At the lower left of the enlarged button operation screen 50D, the same "BACK" icon as the enlarged PC operation screen 50C is displayed, and its function is also the same as that of the enlarged PC operation screen 50C.

The enlargement button operation screen 50D is displayed on the remote terminal 12 as follows. That is, in a state where the main monitor screen 50A is displayed on the remote terminal 12, when an area in which a plurality of button images 60 are arranged is operated from the remote terminal 12, the operation switching unit 26 transmits the operation to the operation unit 16 as an operation targeting the operation unit 16. The operation unit 16 that has received this requests the control unit 28 to perform layout change control in order to generate the enlargement button operation screen 50D. Upon receiving this request, the control unit 28 performs layout change control to cause the video synthesizing unit 22 to generate the enlargement button operation screen 50D. The image synthesizing unit 22 synthesizes the image monitor screen input from the plurality of system devices 46B and/or the PC operation screen input from the plurality of system devices 46A with the screen display unit 88 of the base image of the enlargement button operation screen 50D provided from the operation unit 16, and generates the enlargement button operation screen 50D.

A video monitor screen and/or a PC operation screen to be synthesized on the screen display section 88 are selected under the control of the control section 28 so as to be necessary for operating the plurality of enlarged button images 84 . After that, the image synthesizing part 22 outputs the generated enlarging button operation screen 50D to the operation switching part 26 together with the sound linked to the image monitor screen when the image monitor screen is synthesized on the screen display part 88.例文帳に追加After that, similarly to the case of the main monitor screen 50A, the operation switching unit 26 transmits the enlarged button operation screen 50D and audio to each of the remote terminals 12A and 12B, and the enlarged button operation screen 50D is displayed on the remote terminals 12A and 12B.

Furthermore, when an enlarged button image 84 imitating a button actually installed in the main control room is operated, it is recognized by the operation unit 16, and a plurality of system devices 46C are controlled by, for example, the control unit 28 so that the function of the actual button linked to the operated enlarged button image 84 is executed. As a result, the actual button operation via the remote terminal 12 is realized. Further, when the enlargement button image 84 corresponding to the monitor switching button image 86 is operated, it is recognized by the operation part 16, and the video control part 18 is controlled by the control part 28 so that the video monitor screen preset to the operated monitor switching button image 86 is displayed on the screen display part 88. - 特許庁Furthermore, in conjunction with this, the audio transmitted from the video synthesizing section 22 to the remote terminal 12 via the operation switching section 26 is switched to that of the video monitor screen displayed on the screen display section 88 . Thus, switching of the video monitor screen displayed on the screen display unit 88 is realized, and FIG. 6 shows how the video monitor screen displayed on the screen display unit 88 is switched from the state of FIG.

Here, in the present embodiment, the temporary operation screen 50E generated as one of the monitoring screens 50 has the same configuration as the enlarged button operation screen 50D shown in FIGS. 5 and 6, and the temporary operation screen 50E is displayed on the remote terminal 12. First, in a state where some monitoring screen 50 such as the main monitoring screen 50A is displayed on the remote terminal 12, a trigger signal is input to the control unit 28 from any one of the plurality of system devices 46C. Upon receiving the trigger signal, the control unit 28 selects the system device 46A to be operated by the remote supervisor from among the plurality of system devices 46A according to the event indicated by the input trigger signal, and further selects the system device 46B that provides the video monitor screen to be displayed to the remote supervisor from among the plurality of system devices 46B. In addition, the control unit 28 selects an operation to be executed in order to deal with the event indicated by the input trigger signal from among the multiple system device 46C operations.

Then, the control unit 28 controls the operation switching unit 26 so that the transmission destination of the operation input from the remote terminal 12 is the system device 46A to be operated selected as described above, and the PC operation screen provided by the system device 46A is input to the image synthesizing unit 22. Further, the control unit 28 controls the video switching unit 20 so that the video monitor screen selected as described above to be displayed is input to the video synthesizing unit 22 . Furthermore, the control unit 28 controls the operation unit 16 so that the base image of the temporary operation screen 50E including the operation button 90 for performing the operation selected as described above is provided to the image synthesizing unit 22. After that, the control unit 28 performs layout change control to cause the video synthesizing unit 22 to generate the temporary operation screen 50E. The image synthesizing unit 22 synthesizes the image monitor screen to be displayed on the screen display unit 88 of the base image of the temporary operation screen 50E provided from the operation unit 16, further synthesizes the PC operation screen of the system device 46A to be operated as necessary, and generates the temporary operation screen 50E. It is assumed that operations to be executed on the system device 46A to be operated by the remote monitor, the system device 46B that provides the video monitor screen to be displayed, and the system device 46C that are selected in response to the trigger signal as described above are set in advance for each type of trigger signal.

When the enlarged button image 84 corresponding to the operation button 90 is operated while the temporary operation screen 50E as shown in FIGS. 5 and 6 is displayed, the operation is recognized by the operation unit 16, and the plurality of system devices 46C are controlled by the control unit 28 so that the operation assigned in advance to the operated operation button 90 is executed. The operation pre-assigned to the operation button 90 here is an operation selected by the control unit 28 as an operation to be executed in order to cope with the event indicated by the input trigger signal. Further, the operation when the enlarged button image 84 imitating the button actually installed in the main control room or the enlarged button image 84 corresponding to the monitor switching button image 86 is operated may be the same as that of the enlarged button operation screen 50D. Furthermore, when the PC operation screen is combined with the temporary operation screen 50E, the PC operation screen can be operated in the same manner as the enlarged PC operation screen 50C.

Next, with reference to FIG. 7, the attendant display function of the monitoring work remote system 10 will be described. The occupant display function is to detect whether or not an occupant is present at the monitoring table in the main control room, and if the occupant is present, notify the remote observer that the occupant is present and who is present. Specifically, the occupant display unit 42 uses a sensor to detect the presence of an occupant at the monitoring console in the main control room, and identifies who the occupant is. This can be realized, for example, by attaching various transmitters that can be detected and identified by the sensor of the person-in-place display unit 42 to the employee ID cards of the persons concerned who may be present at the monitoring table. Then, when detecting and identifying a person present, the person display unit 42 outputs a display element indicating that the person is present and a display element indicating who the person is to the video synthesizing unit 22. - 特許庁In this embodiment, the former display element is the person silhouette 64 and the latter display element is the person name plate 66 . The image synthesizer 22 receiving this synthesizes the silhouettes 64 of the persons present and the name plates 66 of the persons present on the main monitoring screen 50A, and displays them on the remote terminal 12 as shown in FIG.

Next, referring back to FIG. 1, a communication conversation function and a telephone answering function, which are realized via the voice control unit 32 and are used by a remote monitor outside the office to communicate by voice, will be described. First, the communication conversation function is a function for a remote supervisor outside the office to have a conversation with a person present in the main control room, the voice uttered by the remote observer outside the office is received by the microphone of the remote terminal 12A, and the voice uttered by the person present in the main control room is received by the microphone of the communication conversation unit 30. Then, the voice received by the microphone of the remote terminal 12A and the voice received by the microphone of the communication conversation unit 30 are mutually transmitted by the voice synthesis unit 34 and the voice transmission unit 36 of the voice control unit 32, the voice uttered by the remote observer is output from the speaker of the communication conversation unit 30, and the voice uttered by the person present is output from the speaker of the remote terminal 12A. This audio transmission system is preferably always connected.

On the other hand, the telephone answering function is a function for the remote supervisor to answer in place of the person present when an extension or outside line is received on the telephone installed in the main control room. Specifically, when the telephone in the main control room receives an incoming call, it is detected by the telephone receiving unit 40, and the telephone receiving unit 40 notifies the control unit 28 of the incoming call. The control unit 28 having received this command controls the operation unit 16, and notifies the remote monitor that the main control room is receiving an incoming call by, for example, blinking the incoming call display element 62 of the main monitoring screen 50A shown in FIG. 2 displayed on the remote terminal 12A. For example, FIG. 8A shows a state in which part of the incoming call display element 62 emits light. In addition, the telephone receiving unit 40 that has detected an incoming call transmits a preset ringing tone to the voice synthesizing unit 34, which is transmitted to the remote terminal 12A via the voice synthesizing unit 34 and the voice transmitting unit 36. As a result, the ring tone is output from the speaker of the remote terminal 12A.

The incoming call display element 62 can be clicked from the remote terminal 12, and when the incoming call display element 62 is operated during an incoming call as described above, the operation unit 16 recognizes it as a call start operation, and the operation unit 16 requests the control unit 28 to control call start. Upon receipt of this request, the control unit 28 controls the call reception unit 40 to start a call, and the call reception unit 40 that receives the call start control starts a call between the telephone in the main control room and the remote terminal 12A. As a result, the voice uttered by the person who made the call to the main control room is output from the speaker of the remote terminal 12A via the telephone receiving section 40 and the voice control section 32, and the voice uttered by the remote supervisor input to the microphone of the remote terminal 12A is transmitted to the person who made the call via the voice control section 32 and the telephone receiving section 40. When the call is started in this way, the transmission of the ring tone to the remote terminal 12 is stopped, and as shown, for example, in FIG.

After that, when the incoming call display element 62 is operated during a call as described above, the operation unit 16 recognizes it as a call end operation, and the operation unit 16 requests the control unit 28 to perform call end control. Upon receipt of this request, the control unit 28 controls the call reception unit 40 to end the call, and the call reception unit 40 that receives the call end control terminates the call between the telephone in the main control room and the remote terminal 12A. This terminates the call between the person calling the main control room and the remote supervisor.

Furthermore, the monitoring work remote system 10 has a function of changing the layout of each monitoring screen 50, and FIG. 9 illustrates a main monitoring screen 50A with a modified layout. The main monitoring screen 50A of FIG. 9 has a simple configuration in which three composite monitor display sections 52 are arranged in the upper stage, and two individual monitor display sections 54 and one operation screen display section 58 are arranged in the lower stage. This layout change includes not only changing the position of each display element, but also adding, changing, and deleting each display element such as the button image 60 . The layout change function is started, for example, when a predetermined area preset on each monitoring screen 50 is operated from the remote terminal 12 . After that, layout change control is performed from the control unit 28 to the image synthesizing unit 22 according to the operation content recognized by the operation unit 16, and the monitor screen 50 reflecting the layout change is displayed on the remote terminal 12.例文帳に追加

The display images shown in FIGS. 2 to 9 do not limit the configuration of the monitoring screen 50 used in the monitoring work remote system 10 according to the embodiment of the present invention. For example, the enlarged button operation screen 50D shown in FIGS. 5 and 6 may be divided into the monitoring screen 50 for button operation and the monitoring screen 50 for checking the video monitor screen. That is, the monitoring screen 50 for button operation includes only the enlarged button images 84 arranged in the lower row among the plurality of enlarged button images 84 shown in FIGS. On the other hand, the monitoring screen 50 for checking the video monitor screen includes only the enlargement button image 84 corresponding to the monitor switching button image 86 arranged in the upper row among the plurality of enlargement button images 84 shown in FIGS.

Also, the temporary operation screen 50E similarly illustrated in FIGS. 5 and 6 may have a configuration different from that of the enlarged button operation screen 50D. Naturally, the configuration of the temporary operation screen 50E, for example, the types of operation buttons 90 to be arranged, etc., may differ according to the trigger signal input from the system device 46C to the control unit 28. Furthermore, the incoming call display element 62 shown in FIGS. 2 and 8 is not limited to a model of a telephone. For example, it may be composed of a text display simply indicating that an incoming call is in progress or that a call is in progress, and a call start operation or a call end operation may be input by operating the text display portion.

Now, according to the embodiment of the present invention having the above configuration, it is possible to obtain the following effects. That is, the monitoring work remote system 10 according to the embodiment of the present invention includes a remote terminal 12, an operation section 16, a video control section 18, an operation switching section 26, and a control section 28, as shown in FIG. The remote terminal 12 is for inputting and outputting information to and from the remote supervisor at a remote monitoring location different from the main control room (monitoring room), and is operated by the remote supervisor and outputs video and audio to the remote supervisor. For this reason, the remote terminal 12 includes operation input means such as a mouse and keyboard, a monitor for outputting video, a speaker for outputting audio, and the like. The operation unit 16 receives an operation input from the remote terminal 12 by the remote observer and detects the content of the operation, and provides the base image of the monitoring screen 50 (see FIGS. 2 to 6) displayed on the remote terminal 12. That is, the operation unit 16 detects what kind of operation is input to which part of the monitoring screen 50 displayed on the remote terminal 12, thereby grasping the details of the operation input by the remote monitor.

The video control unit 18 actually generates the monitoring screen 50 to be displayed on the remote terminal 12, and generates the monitoring screen 50 using the video monitor screen and/or the PC operation screen provided by the plurality of system devices 46 and the base video of the monitoring screen 50 provided from the operation unit 16 as described above. That is, the video control unit 18 selects a video monitor screen or a PC operation screen to be displayed in the base video based on the configuration of the base video of the monitoring screen 50 and the control by the control unit 28, and generates the monitoring screen 50 by synthesizing them with the base video. Therefore, it is possible to generate the monitoring screen 50 with various arbitrary layouts including arbitrary display elements according to the configuration of the base video and the control by the video control unit 18 . Further, when the generated monitoring screen 50 includes a video monitor screen linked with audio, the video control part 18 adds at least a part of the audio provided from a plurality of system devices 46B linked to the video monitor screen to the generated monitoring screen 50 as required. As a result, when the monitor screen 50 is displayed on the remote terminal 12 , the sound of the video monitor screen included in the monitor screen 50 can be output from the remote terminal 12 .

The operation switching unit 26 switches the transmission destination of the operation input from the remote terminal 12 among the operation unit 16 and the plurality of system devices 46A, and is therefore interposed between the remote terminal 12 and the operation unit 16 and the plurality of system devices 46A. Then, when the PC operation screen is operated on the monitor screen 50 displayed on the remote terminal 12, the operation switching part 26 transmits the operation contents to the system equipment 46A providing the operated PC operation screen so that the system equipment 46A can be operated from the remote terminal 12. - 特許庁On the other hand, when an operation other than the PC operation screen is input from the remote terminal 12 , the content of the operation is transmitted to the operation unit 16 . The operation switching unit 26 is also interposed between the remote terminal 12 and the video control unit 18, and plays a role of transmitting the monitoring screen 50 generated by the video control unit 18 as described above from the video control unit 18 to the remote terminal 12.

The control unit 28 controls the video control unit 18, the operation switching unit 26, and at least some of the system devices 46C based on the operation received by the operation unit 16. FIG. That is, the control unit 28 controls the video control unit 18 so as to change the monitoring screen 50, change the layout of the monitoring screen 50, change the display elements of the monitoring screen 50, etc. according to the operation content detected by the operation unit 16. In addition, the control unit 28 controls the operation switching unit 26 so that the transmission destination of the operation input from the remote terminal 12 can be switched between the operation unit 16 and the plurality of system devices 46A according to the operation content detected by the operation unit 16. Furthermore, the control unit 28 directly controls at least a portion of the plurality of system devices 46C according to the operation content detected by the operation unit 16. FIG.

With the configuration described above, the monitoring work remote system 10 according to the embodiment of the present invention can display a video monitor screen and a PC operation screen, output necessary audio, etc. in real time via the remote terminal 12 in response to an operation input from the remote terminal 12, and can operate and control a plurality of system devices 46. Therefore, at a remote monitoring location different from the main control room, the remote monitor can support and execute operation monitoring work (monitoring work) in an environment as if they were actually in the main control room. In addition, since the monitor screen 50 displayed on the remote terminal 12 can freely add, change, or delete display elements, and change the layout, etc., the display of the appropriate monitor screen 50 according to the contents of monitoring can efficiently proceed with operation monitoring work. As an example, it is possible to display a main monitoring screen 50A (see FIGS. 2 and 9) that displays various information necessary for operation monitoring work at once, and a video monitor enlarged screen 50B as shown in FIG. 3 and a PC operation enlarged screen 50C as shown in FIG. Moreover, by controlling via the operation switching unit 26, the video control unit 18, etc., the existing system equipment 46 can be introduced without modification.

Further, in the monitoring work remote system 10 according to the embodiment of the present invention, the remote monitoring place for remotely executing and supporting the operation monitoring work by the remote monitor is located outside the television broadcasting station, and the remote terminal 12A installed there is connected to the operation switching unit 26 via the Internet. This makes it possible to use an arbitrary location outside the TV broadcasting station, such as the remote monitor's home, as a remote monitoring location, as long as the environment for using the Internet is in place.

Furthermore, in the monitoring work remote system 10 according to the embodiment of the present invention, the remote monitoring place for remotely executing and supporting the operation monitoring work by the remote monitor may be inside the television broadcasting station. As a result, even when the main control room cannot be used due to measures against infectious diseases, or when monitoring from a separate room becomes necessary due to an increase in the number of monitoring items, etc., any room within the TV broadcasting station can be used as a remote monitoring location, enabling operation monitoring work to be performed without problems.

Further, in the monitoring work remote system 10 according to the embodiment of the present invention, the operation unit 16 provides the base image of the main monitoring screen 50A as one of the monitoring screens 50 as shown in FIG. 2. The main monitoring screen 50A is the main screen displayed on the remote terminal 12 during the remote monitoring work. For this reason, it is preferable to display other monitoring screens 50 starting from the main monitoring screen 50A, or to arrange display elements displayed in the actual main control room on the main monitoring screen 50A. Such a main monitoring screen 50A includes, as display elements, a display of a video monitor screen and a PC operation screen, and a plurality of button images 60, and the video monitor screen and PC operation screen provided by the plurality of system devices 46 are arranged, for example, the same as those displayed in the main control room.

The plurality of button images 60 are linked to the plurality of buttons installed in the main control room and imitate the plurality of buttons. The video control unit 18 that generates the main monitoring screen 50A from the base video lights each of the plurality of button images 60 included in the main monitoring screen 50A in conjunction with the lighting status of the button of the main control room to which it is linked. As a result, in addition to the video monitor screen and PC operation screen that are actually displayed in the main control room, it is possible to reproduce in real time the lighting conditions of the plurality of buttons arranged in the main control room. Therefore, from the main monitoring screen 50A displayed on the remote terminal 12, it is possible to collectively comprehend the information necessary for operation monitoring work.

Further, in the monitoring work remote system 10 according to the embodiment of the present invention, the layout of at least a part of the image monitor screen, the PC operation screen, and the plurality of button images 60 in the main monitoring screen 50A imitates the actual layout of the image monitor screen, the PC operation screen, and the plurality of buttons in the main control room. As a result, the display of the video monitor screen and the PC operation screen, the plurality of buttons and their lighting conditions can be reproduced in real time by simulating the actual layout in the main control room. Therefore, although the remote monitoring location is different from the main control room, the work environment can be made closer to the actual main control room, and the operation monitoring work can be efficiently executed even remotely.

Furthermore, the monitoring work remote system 10 according to the embodiment of the present invention displays an enlarged button operation screen 50D as shown in FIGS. 5 and 6 starting from the main monitoring screen 50A, and realizes operation of a plurality of buttons installed in the main control room via the enlarged button operation screen 50D. Therefore, when the operation unit 16 detects that the remote terminal 12 has operated the area in which the plurality of button images 60 are arranged on the main monitoring screen 50A, the operation unit 16 notifies the control unit 28 of the operation. The image control unit 18 that has received the enlargement button control generates an enlargement button operation screen 50D and causes the remote terminal 12 to display it. This enlarged button operation screen 50D includes, as display elements, a plurality of enlarged button images 84 obtained by enlarging the plurality of button images 60 while maintaining the linkage with the plurality of buttons in the main adjustment room, and a screen display section 88 for displaying a video monitor screen and/or a PC operation screen.

Then, when the operation unit 16 detects that any one of the plurality of enlargement button images 84 on the enlargement button operation screen 50D has been operated by the remote terminal 12, the operation unit 16 transmits information on the operated enlargement button image 84 to the control unit 28. Upon receiving the information, the control unit 28 controls at least some of the plurality of system devices 46C so that the functions of the actual buttons in the main adjustment room linked to the operated enlarged button image 84 are executed. As a result, the buttons actually arranged in the main adjustment room can be operated from the remote terminal 12 without any problem, and by displaying the enlarged button image 84 linked to the necessary button according to the situation, it is possible to perform control via various buttons. Moreover, since the operation input is performed on the enlarged button image 84 displayed in an enlarged manner, it is possible to suppress the occurrence of erroneous operations.

Further, in monitoring work remote system 10 according to the embodiment of the present invention, multiple monitor switching button images 86 are included in multiple enlargement button images 84 included in enlargement button operation screen 50D. Then, when detecting that any one of the plurality of monitor switching button images 86 has been operated by the remote terminal 12 , the operating unit 16 transmits information on the operated monitor switching button image 86 to the control unit 28 . The control unit 28 having received the information controls the video control unit 18 so that the video monitor screen preset in the operated monitor switching button image 86 is displayed on the screen display unit 88 . As a result, the video monitor screen displayed on the screen display section 88 of the enlargement button operation screen 50D can be switched to an arbitrary video monitor screen by operating any one of the plurality of monitor switching button images 86. FIG. Moreover, by making the display of the video monitor screen by the screen display part 88 independent from any monitor screens installed in the main control room, any video monitor screen can be confirmed through the screen display part 88 without interlocking the display with the actual monitor screen.

Furthermore, in the monitoring work remote system 10 according to the embodiment of the present invention, the remote terminal 12 includes a microphone for inputting the remote monitor's voice, and the monitoring work remote system 10 further includes a communication conversation unit 30 and a voice control unit 32 as shown in FIG. The communication conversation unit 30 includes a microphone and a speaker for the persons present in the main control room, the voice of the person present is input through the microphone, and the voice is output to the person present through the speaker. The voice control unit 32 transmits the voice of the remote supervisor received by the remote terminal 12 to the communication conversation unit 30 and transmits the voice of the person present received by the communication conversation unit 30 to the remote terminal 12 . As a result, the voice uttered by the remote observer is transmitted to the persons present in the main control room via the microphone of the remote terminal 12, the voice control unit 32, and the speaker of the communication conversation unit 30, and the voice uttered by the person present in the main control room is transmitted to the remote observer via the microphone of the communication conversation unit 30, the voice control unit 32, and the speaker of the remote terminal 12. As a result, since the remote supervisor at the remote monitoring location and the person present at the main control room can have a direct conversation, information can be quickly exchanged and confirmed, and work can be performed as if the remote supervisor were in the main control room.

In addition, the monitoring work remote system 10 according to the embodiment of the present invention further includes a telephone reception unit 40, and this telephone reception unit 40 detects an incoming call to the telephone installed in the main control room and notifies the control unit 28 and the voice control unit 32 of the incoming call. The control unit 28 receiving this notification performs incoming call control on the operation unit 16, and the operation unit 16 that receives the incoming call control provides the video control unit 18 with the base image of the monitoring screen 50 including the incoming call display element 62 as shown in FIG. Here, the incoming call display element 62 is a display element that notifies the remote monitor that the telephone installed in the main control room is receiving an incoming call and allows the remote monitor to perform a call start operation and a call end operation. On the other hand, the voice control unit 32, which has received the notification that the call is being received, transmits a preset ring tone to the remote terminal 12 and causes the speaker of the remote terminal 12 to output the ring tone. As a result, the incoming call display element 62 can visually notify the remote monitor at the remote monitoring location that the telephone in the main control room is receiving an incoming call, and the ring tone can also audibly notify the incoming call.

Then, when the remote monitor performs a call start operation on the incoming call display element 62 displayed on the remote terminal 12, the operation unit 16 requests the control unit 28 to perform call start control, and the control unit 28 receiving this request controls the call reception unit 40 to start the call. Then, the telephone receiving unit 40 interposed between the telephone in the main control room and the voice control unit 32 performs control so that a call is started between them, and the voice control unit 32 performs two-way voice communication. As a result, a call can be made between the person who called the main control room and the remote monitor as if the call had been made directly. Thereafter, when the remote monitor performs a call termination operation on the incoming call display element 62 displayed on the remote terminal 12, the operation unit 16 requests the control unit 28 to perform call termination control, and the control unit 28 receiving this request performs call termination control on the telephone reception unit 40. - 特許庁Then, the telephone receiving section 40 performs control to terminate the call, and the voice control section 32 terminates the two-way voice communication. This allows the call between the person calling the main control room and the remote supervisor to be terminated as if the call had been hung up.

With the configuration as described above, the monitoring work remote system 10 according to the embodiment of the present invention makes it possible to answer the incoming call from the remote monitoring location even if there is an incoming call for an extension or outside line in the main control room and the main control room cannot answer the call for some reason. In particular, when a failure occurs or a special program is being handled, the telephone in the main control room receives calls more frequently than usual.

Further, in the monitoring work remote system 10 according to the embodiment of the present invention, the control unit 28 selects the system device 46A to be operated by the remote supervisor and the system device 46B providing the video monitor screen to be displayed to the remote supervisor from among the plurality of system devices 46 in response to the trigger signals input from the plurality of system devices 46C. Furthermore, the control unit 28 selects an operation to be executed to deal with the event indicated by the input trigger signal from among the operations for the plurality of system devices 46, and controls the video control unit 18 based on the selected operation. Then, the video control unit 18 that has received the control from the control unit 28 generates a temporary operation screen 50E (see FIGS. 5 and 6) for responding to the event indicated by the trigger signal input to the control unit 28. FIG.

This temporary operation screen 50E includes a video monitor screen of the system device 46B that provides a video monitor screen to be displayed to the remote monitor, a PC operation screen of the system device 46A that is to be operated by the remote monitor, and/or at least one operation button 90 for performing an operation to be executed to deal with the event indicated by the trigger signal. The operation button 90 here may have the same function as the button actually installed in the main control room (that is, the button equivalent to the enlarged button image 84 imitating the button actually installed in the main control room), or may not be installed in the main control room. As a result, the remote terminal 12 is presented with a video monitor screen to be confirmed, a PC operation screen of the system device 46A to be operated, and/or an operation button 90 for performing the operation to be executed, which are necessary for responding to the event indicated by the trigger signal. Therefore, even when an operation for responding to an event indicated by a trigger signal, such as handling a failure or sending out a bulletin, is required, the remote monitor can quickly and accurately respond by operating the PC operation screen or the operation button 90 while checking the video monitor screen to be checked on the temporary operation screen 50E.

Furthermore, the monitoring work remote system 10 according to the embodiment of the present invention is not limited to application to operation monitoring work of television broadcasting, but can be applied to various monitoring work performed in various industries such as electric power, railway, security, disaster prevention, and building management.
