DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a plant monitoring and control apparatus for monitoring and operating a plant by displaying a plant state on a display device such as a CRT.

[0002]

2. Description of the Related Art Plant monitoring and control in a plant monitoring and control device using a display device such as a CRT is performed by an operator using a monitoring screen displayed on the plant monitoring and control device as a window to acquire plant information and operate the plant. It is carried out.

In a conventional plant monitoring operation, when there is information to be conveyed, such as operational precautions, a verbal instruction by an administrator to an operator, a notification at the time of handover of an operator, or a monitoring room in which a plant device is installed. Posted on the bulletin board.

[0004] In this method, the above information is stored in the memory of the operator, but it is not reflected on the monitoring screen displayed on the plant monitoring and control device serving as a window when the operator operates the plant. Absent.

According to Japanese Patent Application Laid-Open No. 2000-172326, there is also a method in which information is expressed in characters, taken into a plant monitoring and control device, and displayed as a memo window.

[0006] In this method, information such as operational precautions can be transmitted using a plant monitoring and control device. However, since a memo window is displayed separately from the monitoring screen, even in this method, the operator can use the memo window. The information is not reflected on the monitoring screen serving as a window when the user operates, and the operator cannot know whether or not the information is registered even by looking at the monitoring screen.

[0007] For this reason, the information is stored as the operator's memory in that the operator must always check whether new information is registered in the memo window and grasp the contents thereof. There is no.

[0008]

In the conventional plant monitoring and control apparatus, information such as operational precautions is not displayed on the monitoring screen. Obtain and store the latest information from the bulletin board and memo window, and when actually operating the plant, make a judgment based on the information obtained above as to "Do you want to perform this operation?" There must be.

For this reason, there is a problem in that correct information is not transmitted to the operator, or an incorrect operation is performed due to a misjudgment due to a wrong memory of the operator.

An object of the present invention is to provide a plant monitoring and control apparatus which can transmit information such as cautions on plant operation to an operator without misunderstanding and prevent erroneous operation caused by an operator's misjudgment.

[0011]

According to the present invention, information such as cautions or notices of an operator on a monitor screen of a plant monitoring and control device is written as characters, figures, voices, still images, and moving images. Means for registering, means for synthesizing the registered information with a monitoring screen and displaying the same, and means for deleting unnecessary information are provided.

The monitoring screen in the plant monitoring and control device is indispensable for the operator to monitor and control the plant. Information such as cautions is registered in the monitoring screen in characters, and the monitoring screen is displayed. By combining and displaying,
When the operator displays the monitoring screen to monitor and operate the plant, he / she always sees the registered character information. For this reason, it is possible to prevent erroneous operation due to information not being transmitted to the operator or accidental forgetting of the operator.

Further, by using a graphic as information to be registered in the monitoring screen, it is possible to notify the operator at a glance of a place that needs attention in the operation of the plant using a graphic such as a circle or an arrow. Becomes further,
By synthesizing and displaying the registered graphic information with the monitoring screen, the operator always sees the registered graphic information when the monitoring screen is displayed to monitor and operate the plant. For this reason, it is possible to prevent erroneous operation due to information not being transmitted to the operator or accidental forgetting of the operator.

[0014] Further, by using voice as information to be registered in the monitoring screen, the voice information is converted into an icon and synthesized and displayed with the monitoring screen, so that when the operator displays the monitoring screen to monitor and operate the plant, Since it is possible to always know that the voice information has been registered, it is possible to prevent a trouble that the operator does not notice the information and to provide a voice transmission means that can be reliably transmitted to the other party.

When trying to convey a lot of information only by text, the operator who receives the information tends to be careful not to read or misunderstand the meaning because of the large number of texts. By using
It is possible to provide information in a form that is easy for the operator to understand.

Further, by reproducing the voice information at the same time as displaying the monitoring screen, it is possible to prevent the trouble that the information is not transmitted due to the fact that the operator noticed the existence of the voice information but did not reproduce it. It becomes possible to make the transmission means more robust.

Further, when a still image is used as information to be registered in the monitoring screen, the still image information is iconified and displayed on the monitoring screen in combination, so that the operator can display the monitoring screen to monitor and operate the plant. In addition, since it is possible to always know that still image information has been registered, it is possible to prevent troubles such that the operator does not notice the information and to provide a still image transmission means that can be reliably transmitted to the other party. Become. By this still image transmission means, when a special operation is required for the operator, the position of the switch to be operated and the operation method are taught using the photograph of the plant equipment or the instruction manual of the plant equipment captured by the image scanner. And an accident due to an operation error can be prevented.

Further, by reproducing the still image information at the same time as displaying the monitoring screen, it is possible to prevent a trouble that the operator is aware of the existence of the still image information but does not transmit the information because he did not reproduce the still image information. The still image transmission means can be made more robust.

Further, by using a moving image as information to be registered in the monitoring screen, converting the moving image information into an icon, and displaying the icon in combination with the monitoring screen, when the operator displays the monitoring screen to monitor and operate the plant, Since it is possible to always know that the moving image information is registered, it is possible to prevent a trouble that the operator does not notice the information, and to provide a moving image transmitting means that reliably transmits to the other party. By this moving image transmission means, when a special operation is required by the operator, the operation procedure is recorded in advance in a video, and the operation content can be accurately transmitted to the operator by displaying as a moving image, Accidents due to operation errors can be prevented. Also, by displaying the monitoring screen and playing back the moving picture information at the same time, the operator is aware of the existence of the moving picture information, but prevents the trouble that the information is not transmitted due to the fact that he did not play the moving picture information. It is possible to make it more robust.

Such a configuration is similar to that of a conventional plant monitoring and control device.

Incidentally, the monitoring screen definition information 121 includes:
Plant 1 captured by the plant information capturing unit 122
Information defining how to display a monitoring screen is stored by a signal of a device constituting 41.
It is created in advance by the manufacturer of the plant monitoring and control device, and is not rewritten unless the configuration of the plant is changed.

Therefore, in the present invention, in order to store information temporarily necessary for plant operation, the plant manager or the operator stores the character information 131, the graphic information 132, and the voice information in the storage device of the process computer 100. Information 133, still image information 134, and moving image information 135 are provided.

When the operator performs an operation of calling a monitoring screen from the operation input unit 153, in addition to the above-described operation of the conventional plant monitoring and control device, the registered object reproducing unit 112 transmits character information 131, graphic information 132, and voice information 133. Based on the still image information 134 and the moving image information 135, characters and figures registered by the operator are reproduced, and an object screen on which an icon indicating that a sound, a still image, and a moving image are registered is generated. This object screen and monitoring screen generator 1
The monitor screen generated by the monitor 13 is synthesized by the screen synthesizer 111 and displayed on the CRT 151.

When the operator performs a registration operation of character information from the operation input unit 153, the operation information is transmitted to the object registration unit 114 through the input processing unit 115, and the object registration unit 114 is input by the operation input unit 153. The registered character is registered in the character information 131.

When the operator performs a registration operation of the graphic information from the operation input unit 153, the operation information is transmitted to the object registration unit 114 through the input processing unit 115, and the object registration unit 114 is drawn by the operation input unit 153. The registered figure is registered in the figure information 132.

When the operator performs a voice information registration operation from the operation input unit 153, the operation information is transmitted to the object registration unit 114 through the input processing unit 115, and the object registration unit 114 is input by the voice input device 142. The registered voice is registered in the voice information 133.

When the operator performs an operation for registering still image information from the operation input unit 153, the operation information is input to the input processing unit 115.
To the object registration unit 114, and the object registration unit 114
The still image inputted by 43 is registered in the still image information 134.

When the operator performs an operation of registering moving image information from the operation input unit 153, the operation information is transmitted to the object registration unit 114 through the input processing unit 115, and the object registration unit 114 is input by the video capture device 144. The created moving image is registered in the moving image information 135.

Note that the audio output device 152 outputs the audio information 13
3 and the moving image information 135 are reproduced.

Next, referring to FIG.
A process when an operation for displaying a monitoring screen in which the information 1 and the graphic information 132 are registered is performed will be described.

The character information 131 includes character management information 201
The screen number indicating the corresponding monitoring screen, the character string registered by the operator, the width of the area for displaying the position, the height of the area for displaying the character string, the size of the character string, and the color code to be displayed are stored. ing.

The graphic information 132 stores a graphic drawn by the operator as a dot image 202. The registered object reproducing unit 112 reads the dot image 202 from the graphic information 132, and further reads the character management information 201 from the character information 131.
3 can be played. The screen 203 and the monitoring screen 204 generated by the monitoring screen generating unit 113 are synthesized by the screen synthesizing unit 111 to become a screen 205 and output to the display device.

In this way, by registering the operational precautions and the like as characters and figures in the character information 131 and the graphic information 132, the registered contents can be combined with the monitoring screen and displayed.

Next, referring to FIG.
A description will be given of a process performed when an operation for displaying a monitoring screen in which the still image information 3, the still image information 134, and the moving image information 135 are registered is performed.

In FIG. 3, the voice information 133 stores a voice file 301 registered by the operator and voice management information 302 for managing the voice file. Audio file 3
No. 01 stores voice recorded by an operator in a storage device, and this technology has already been put to practical use. Also,
The audio file 301 has an identifier "." At the end of the file name so that it can be easily recognized that the audio file is an audio file.
wav "is added. In the voice management information 302,
A screen number indicating a corresponding monitoring screen, a file name indicating a registered audio file 301, an icon display position on the screen, and presence / absence of automatic reproduction are managed.

When the operator performs an operation for displaying the monitoring screen in which the voice information is registered, the registered object reproducing unit 112 outputs the voice management information 302 from the voice information 133.
Is acquired, and a voice icon 308 is generated on the object screen 307 based on the information. The still image information 134 stores a still image file 303 registered by the operator and still image management information 304 for managing the file.

The still image file 303 is a file in which the operator captures a still image and stores it in a storage device. As an input device for performing the operation, a digital camera or an image scanner has already been put to practical use. Further, in the still image file 303, the identifier ".jp" is added to the end of the file name so that it can be easily recognized that the file is a still image file.
g "is added.

The moving image information 135 stores a moving image file 305 registered by the operator and moving image management information 306 for managing the file. In addition, an identifier “.mov” is added to the end of the file name of the moving image file 305 so that the file is easily recognized as a moving image file. The moving image file 305 is a file in which an operator captures a moving image and stores the moving image in a storage device, and a video capture device for performing this operation has already been put to practical use.

Still picture management information 304 and moving picture management information 30
6 is the same format as the voice management information 302. When the operator performs an operation for displaying a monitoring screen in which the still image information and the moving image information are registered, the registered object reproducing unit 1
12 acquires still image management information 304 and moving image management information 306 from the still image information 134 and moving image information 135, and obtains a still image icon 309 and a moving image icon 310 based on the information.
Is generated on the object screen 307.

The object screen 307 generated by the registered object reproducing unit 112 is synthesized with the monitoring screen 311 by the screen synthesizing unit 111 and displayed as a screen 312.
Further, the registered object reproduction unit 112 reproduces the audio file 301 specified to be automatically reproduced by the audio management information 302 and outputs the audio file 301 to the audio output device 152.

As described above, what is difficult to convey using only characters and figures can be conveyed without misunderstanding using audio, still images, and moving images. In addition, by the automatic reproduction setting, the operator does not need to perform any special operation for reproduction, and has a means for reproducing simply by calling the monitoring screen, so that important messages can be reliably transmitted to the operator.

FIG. 4 shows a flow of processing of the registered object reproducing unit 112 when an operator performs an operation for displaying a monitoring screen.

At step 402, acquisition of graphic information is attempted, and it is determined whether graphic information is present. (Step 403)
If there is graphic information, the graphic registered by the operator is reproduced as an object screen according to the contents (step 40).
4). Next, character information is obtained (step 40).
5) The individual character information obtained is drawn on the object screen (steps 406 to 408). Next, voice information is acquired (step 409), and a voice icon is drawn on the object screen for each acquired voice information (step 411).

The voice information includes voice management information 3 shown in FIG.
As indicated by 02, it includes designation of whether or not the reproduction is automatic. By referring to this, if it is an object of automatic reproduction, its file name is temporarily stored (steps 412 to 41).
3). Similarly, information acquisition, icon drawing, and registration of a file name for automatic reproduction are performed for still image information and moving image information. (Steps 417 to 428) When the processing shown in FIG. 4 is completed, the processing in FIG. 5 is executed in order to automatically reproduce audio information, still image information, and moving image information.

In FIG. 5, during the loop 1 shown in steps 502 and 509, the file names registered in steps 413, 421 and 427 in FIG. In the reproduction process, it is determined whether the file name extracted above is an audio file (step 503). If the file is an audio file, the file is reproduced as an audio file and the result is output to the audio output device 152 (step 506). .

By the way, as described with reference to FIG. 3, the identifier is added to determine whether the file is an audio file from the file name. If this identifier is ".
If it is "wav", it can be determined that the file is an audio file. Also, a method of recording and reproducing audio as a file in a storage device on a computer has already been put to practical use.

If it is determined in step 503 of FIG. 5 that the file is not an audio file, it is next determined whether the file is a still image file (step 504). as a result,
If it is a still image file, the contents of the still image file are displayed (step 507). If it is not a still image file, it is determined whether it is a moving image file (step 50).
5) If it is a moving image file, the contents are reproduced.

A method of recording a still image or a moving image as a file in a storage device on a computer, and displaying and reproducing the file has already been put to practical use.

As described above, in FIG. 4, information registered in advance by the operator can be combined with the monitoring screen and displayed. The monitoring screen is an indispensable element for plant monitoring and operation, and the operator always sees the monitoring screen when monitoring and operating the plant. I can tell the staff.

Further, the processing of reproducing the audio information, the still picture information, and the moving picture information of FIG. 5 is performed after the processing of FIG. 4, so that the sound, the still picture, and the moving picture are reproduced simultaneously with the display of the monitoring screen. be able to. Therefore, it is possible to prevent information from being transmitted without the operator performing the regeneration operation.

Next, a means for reproducing the voice stored in the storage device by the operator selecting a voice icon, a still image icon, and a moving image icon displayed on the monitor screen by using an input device such as a mouse will be described with reference to FIG. Will be explained.

FIG. 6A shows an audio icon 601, a still image icon 602, and a moving image icon 60 on the monitoring screen 600.
This is an example in which 3 is displayed.

The lower part of the monitoring screen is a column for displaying a function menu, and displays an "edit" menu 604 for the operator to register and edit necessary information. When the operator selects the place where the icon is displayed with the mouse, the operator selects FIG.
As shown in (b), the selected icon is displayed in a bold frame, and a “playback” menu 615 is displayed in the lower function menu.

When the operator selects the "play" menu 615 with the mouse, the file corresponding to the selected icon is played. At this time, if the file to be reproduced is a still image file or a moving image file, a window 621 in FIG. 6C is displayed, and an image is displayed in the image display area 622. After viewing the image, the operator can delete the window 621 by selecting a “close” button 623.

The processing for executing the processing shown in FIG. 6 will be described with reference to FIG.

FIG. 7 shows the processing when the operator selects an arbitrary point on the monitoring screen with the mouse.

First, the position of the mouse is detected, and the coordinates selected by the operator are checked (step 702). Next, it is determined from the audio management information 302, the still image management information 304, and the moving image management information 306 shown in FIG. 3 whether there is an audio icon, a still image icon, or a moving image icon at the selected position (step 703). If there is an icon, a file name corresponding to the icon is registered (step 704).
Then, a frame is displayed as a thick frame like the icon 612 in FIG. 6B (step 705), and a “playback” menu 615 is displayed (step 706). Here, only the latest file name is registered.

If no icon exists at the selected position,
Display the thin frame of the icon already selected (Step 7
07) and delete the "playback" menu from the menu (step 708). Further, it is determined whether or not the selected position is a place of the “edit” menu (step 709), and if so, the process proceeds to the object editing process. This object editing process is for the operator to register necessary information, and will be described later in detail.

If the selected position is not the "edit" menu, it is determined whether the selected position is the "play" menu (step 7).
10). If the selected position is the "playback" menu, and the file name registered in step 704 is other than an audio file, the image display window 621 of FIG. 6C is displayed (step 712) and played back (step 713).

In the case of an audio file, the audio file is reproduced without displaying the window 621 in FIG. 6C (step 71).
3). The file reproduction process is the same as the process shown in FIG.

As described above, the information stored in the form of icons, voices, still images, and moving images displayed on the monitoring screen can be reproduced, and the information can be transmitted in a manner that is easy for the operator to understand. .

Next, registration and deletion of information to be displayed in combination with the monitoring screen will be described.

The information synthesized and displayed on the monitoring screen is shown in FIG.
The character information 131 and the graphic information 132 in FIG. 3 and the audio information 133, the still image information 134 and the moving image information 13 in FIG.
The fact that it is stored as 5 has already been described. Therefore, it is sufficient to register and delete such information.

FIGS. 8A, 8B, and 8C are examples of screens for registering and deleting the information displayed on the monitoring screen. The monitoring screen is actually displayed on the monitoring screen display units 800, 810, and 820, but is omitted in FIG.

When the operator selects the "edit" menu 604 with the mouse on the screen shown in FIG.
The editing screen of (a) is displayed.

Here, the "character" menu 80 at the bottom of the screen

The input character is displayed as a character object 811 as shown in FIG. 8 (b), and as the character management information 201 in FIG.
Store in the above storage device.

By the way, the character management information 201 includes items for managing the size and color of the characters to be displayed.
Means for designating these at the time of character input is required, but they are not directly related to the present invention, and thus description thereof is omitted.

Deletion of the registered character is performed as shown in FIG.
After selecting the character object 821 to be deleted with the mouse,
This can be done by selecting the “Delete” menu 829.

On the screen shown in FIG. 8A, when the operator selects the "drawing" menu 802 with the mouse, the figure can be drawn.

The drawing of the figure is performed when the mouse pointer 901 is moved by the mouse in FIG.
If the mouse button is pressed, the mouse pointer 90
This can be done by displaying a locus of one as a line.

The drawn figure is stored as a dot image in the storage device in the process calculation period 100. In FIG. 9B, the user can select the “image deletion” menu 912 in FIG. 9B, and then move the mouse pointer 911 to the position of the graphic to be deleted, and then press the mouse button. With this operation, the figure around the mouse pointer 911 can be erased. By moving the mouse while holding down the mouse button, the figure can be erased along the locus of the mouse pointer 921 as shown in FIG. 9C.

On the screen shown in FIG. 8A, when the operator selects the "voice" menu 805 with the mouse and then selects an arbitrary place on the monitor screen display section 800, the screen shown in FIG.
The registration window 1001 shown in FIG. Here, when the “New Import” button 1003 is selected,
The voice is captured through the voice input device 142, and the voice file 301 and the voice management information 302 shown in FIG. 3 are created and stored in the voice information 133. Note that a method for storing audio as a file on a storage device has already been put to practical use.

When a previously created sound file can be used as the sound file 301, the sound file can be selected from the file list display 1002 in the registration window 1001 of FIG. In this case, only the voice management information 302 shown in FIG. 3 is created.

The voice management information 302 thus created
Is displayed as a sound icon 1011 on the monitoring screen 1010 in FIG. 10B.

If the voice icon 1011 is no longer needed, first select the voice icon 1011 with the mouse,
When the “Delete” menu 1012 is selected, FIG.
Is displayed, the management information of the voice icon 1011 is deleted from the voice management information 302 in FIG. 3 by selecting the “Delete icon only” button 1022 or the “Delete icon and file” button 1023. Thus, the voice icon 1011 displayed on the monitoring screen can be deleted. If the audio file 301 in FIG. 3 is unnecessary, it can be deleted together with the icon by selecting the “delete icon and file” button 1023 in FIG. If the user wants to save the audio file 301 so that he / she can use it later, the user can click the “Delete icon only” button 1 in FIG.
By selecting 022, only the icon can be deleted.

In FIG. 8A, a “still image” button 8
Even when the “06” or “movie” button 807 is selected, registration and deletion of an icon to be superimposed and displayed on the monitoring screen can be performed by the same means as the method described with reference to FIG.

As described above, the operator and the manager can register characters, graphics, audio icons, still image icons, and moving image icons that are combined and displayed on the monitoring screen for monitoring and operating the plant.

Next, when the operator displays the monitoring screen,
A setting method for automatically reproducing a sound icon, a still image icon, and a moving image icon will be described.

The information that is automatically reproduced when the monitoring screen is displayed includes the audio management information 302 and the still image management information 3 shown in FIG.
04, the video management information 306 includes information of automatic playback. Therefore, it can be realized by editing the presence / absence of automatic reproduction on the management information.

In FIG. 6A, an "edit" menu 60
If the voice icon 601 is selected after selecting the item No. 4, and if the voice management information 302 is not registered to automatically reproduce the voice icon 601, the “automatic” menu 1101 is displayed as a thin frame as shown in FIG. I do.

In FIG. 11A, the "automatic" menu 11
When "01" is selected, the audio management information 302 registers that the audio icon 601 is to be automatically reproduced, and the "automatic" menu is displayed in a bold frame as shown in FIG. Also, a diagonal line 1161 indicating that the automatic reproduction is registered is displayed on the audio icon 601.

Since the hatched line 1161 is always displayed when displaying the icon set to be automatically reproduced, not only when the automatic reproduction is registered, even if the operator is looking at the monitoring screen, any information from the icon is automatically displayed. It is possible to easily determine whether the data is to be reproduced.

In FIG. 11B, the "automatic" menu 11
When "01" is selected, the audio management information 302 registers that the audio icon 601 is to be automatically reproduced, the oblique line 1161 indicating that the audio icon 601 is registered for automatic reproduction is deleted, and the "automatic" is displayed as shown in FIG. "Menu 110
1 is displayed in a thin frame.

In this way, every time the "auto" menu is pressed, the setting of whether or not to automatically reproduce can be switched.

According to the same procedure as described above, even if the selected icon is a still image icon or a moving image icon, it is possible to set whether or not to automatically reproduce the icon.

The operator may overlook the icons only by superimposing them on the monitoring screen without reproducing them. However, by performing the setting for automatically reproducing the icons when the monitoring screen is displayed as described above, the operator can make the setting. , It is possible for the operator to always watch.

[0090]

As described above, information such as precautions is registered in characters on the monitor screen which is indispensable for the operator to monitor and control the plant, and is displayed in combination with the monitor screen. Thus, when the operator displays the monitoring screen to monitor and operate the plant, he / she always sees the registered character information. For this reason, it is possible to prevent erroneous operation due to information not being transmitted to the operator or accidental forgetting of the operator.

Further, by using a figure as information to be registered in the monitoring screen, it is possible to notify the operator of a place to which attention must be paid in the operation of the plant so that the operator can recognize it at a glance using a figure such as a circle or an arrow. Becomes further,
By synthesizing and displaying the registered graphic information with the monitoring screen, the operator always sees the registered graphic information when the monitoring screen is displayed to monitor and operate the plant. For this reason, it is possible to prevent erroneous operation due to information not being transmitted to the operator or accidental forgetting of the operator.

Also, voice is used as information to be registered in the monitoring screen, and the voice information is converted into an icon and synthesized and displayed on the monitoring screen, so that when the operator displays the monitoring screen to monitor and operate the plant, Since it is possible to always know that the voice information has been registered, it is possible to prevent a trouble that the operator does not notice the information and to provide a voice transmission means that can be reliably transmitted to the other party.

When trying to convey a lot of information only by text, the operator who receives the information tends to be careful not to read or misinterpret the meaning because of the large number of texts. By using
It is possible to provide information in a form that is easy for the operator to understand.

Further, by reproducing the voice information at the same time as displaying the monitoring screen, it is possible to prevent a trouble that the operator is aware of the existence of the voice information but the information is not transmitted because the voice information is not reproduced. It becomes possible to make the transmission means more robust.

Further, a still image is used as information to be registered in the monitoring screen, and the operator displays the monitoring screen to monitor and operate the plant by converting the still image information into an icon and displaying it on the monitoring screen. In this case, it is possible to always know that the still image information has been registered, so it is possible to prevent troubles such as the operator not knowing the information and to provide a still image transmission means that can be reliably transmitted to the other party When a special operation is required by the operator, the still image transmitting means can provide a photograph of the plant equipment or an instruction manual of the plant equipment captured by an image scanner with the position and operation method of the switch to be operated. It is possible to teach by using, and it is possible to prevent accidents due to operation errors.

Further, by reproducing the still image information at the same time as displaying the monitoring screen, it is possible to prevent a trouble that the operator is aware of the existence of the still image information but does not reproduce the information because the reproduction is not performed. The still image transmission means can be made more robust.

Also, a moving image is used as information to be registered in the monitoring screen, and the moving image information is iconified and displayed as a composite with the monitoring screen, so that when the operator displays the monitoring screen to monitor and operate the plant, Since it is possible to always know that the moving image information is registered, it is possible to prevent a trouble that the operator does not notice the information, and to provide a moving image transmitting means that reliably transmits to the other party. By this moving image transmission means, when a special operation is required by the operator, the operation procedure is recorded in advance in a video, and the operation content can be accurately transmitted to the operator by displaying as a moving image, Accidents due to operation errors can be prevented.

Further, by displaying the monitoring screen and playing back the moving picture information at the same time, it is possible to prevent a trouble that the operator is aware of the existence of the moving picture information but the information is not transmitted because he did not play back the moving picture information. It becomes possible to make the transmission means more robust.
