Description

  The present invention relates to a monitoring device, a monitoring method, and a program

  There is a monitoring system that uses an alarm sound or a screen display output from a monitored device so that a person can monitor the state of the device to be monitored (monitored device). Such a monitoring system includes a monitored device, a monitoring target, and a comprehensive monitoring device. Here, the monitored device is a device to be monitored (monitored) or a set of devices, and is a GUI (Graphical User Interface) for transmitting the current state to the monitor or an alarm sound generating means. It has either or both.

  The monitoring target is a device that is a monitoring target of the monitoring person, but does not have a GUI and an alarm sound generating means for transmitting a state to the monitoring person. Through the GUI function and sound generation function of the PC, there is a means for appealing to the visual and auditory senses of the supervisor in an easy-to-understand manner, and it is handled as a monitored device. For example, a device whose status display to the monitor only has LED color display does not have a GUI and does not have a means of appealing to the monitor in an easy-to-understand manner. It is necessary to judge whether.

  The comprehensive monitoring device is a device having a function of displaying a list of alarms on the screen by inputting alarm outputs of a plurality of monitoring targets and monitored devices. The comprehensive monitoring device is also a device that is monitored from the outside, and has a function of generating a GUI and an alarm sound, and thus is included in the monitored device. By incorporating a plurality of monitored devices into the integrated monitoring device, the number of monitors and speakers to which the supervisor should pay attention is reduced, the burden on the supervisor is reduced, and the operability is improved. Is used.

  The comprehensive monitoring device reads different types of alarm signals from each monitored device and monitoring target, and converts them into contact signals indicating “alarm output” or “no alarm output”. For example, an SNMP (Simple Network Management Protocol) trap message transmitted by a certain monitoring target is “converted” into information “monitoring target b is issuing an alarm”. Then, the comprehensive monitoring device conveys the state of each contact point as a GUI screen or sound so as to be easily understood by the monitor.

  Examples of a monitoring system using such a comprehensive monitoring device are shown in Patent Literature 1 and Patent Literature 2. The monitoring system described in Patent Literature 1 centrally manages the temperature, sound, gas concentration, and radiation measurement values of the environment to be monitored by a personal computer or a workstation. Then, two threshold values are set in advance for each measurement value, and three states of normal, caution, and abnormality are determined depending on a combination of whether each measurement value is higher or lower than these threshold values.

  The monitoring system described in Patent Document 2 stores monitoring target monitoring data set in advance before starting operation of the monitoring system in a database, and displays the monitoring result via the Web.

  As described above, by incorporating a plurality of monitored devices and monitoring targets into the integrated monitoring device, the burden on the supervisor is reduced and operability is expected to be improved. However, since the signal that can be received by the comprehensive monitoring device is only a simple contact signal indicating whether or not an alarm has been generated, the supervisor cannot grasp the contents indicated by the alarm. In addition, data to be monitored and conditions for generating an alarm are fixed in advance, and it is difficult to change them afterwards.

  The present invention has been made in view of such problems, and can be set to output desired information when the output from the monitoring target satisfies a desired condition. An object is to provide a monitoring device whose settings can be changed.

In order to solve the above-described problems and achieve the object, a monitoring device according to an embodiment of the present invention is:

<1. Overview>
First, the outline of the present invention will be described with reference to FIGS. 1 to 5 showing an overview of the configuration and processing of a monitoring apparatus according to an embodiment of the present invention, and FIGS. 42 and 43 showing the general configuration of a monitoring system. To state.

  FIG. 42 shows an example of a conventional monitoring system. The monitoring system includes elements of a monitored device, a monitoring target, a comprehensive monitoring device, a monitor, and a monitoring room. Here, the supervisor refers to a person who constantly monitors the alarm sound and GUI (monitor display) of the general monitoring apparatus and the monitored apparatus.

  The monitoring room is a room where a monitoring person performs monitoring. Each alarm display monitor and alarm sound generating speaker are integrated. It is often disadvantageous from the standpoint of maintainability that the general monitoring device, monitored device, and device body to be monitored are located in the same room as the monitoring room. Usually, the device body is gathered in a stacking room such as a rack room. Only video (monitor) output and audio output are extended to the monitoring room. That is, “the screen and sound output by the device are at hand” but “the device body is far away”.

FIG. 43 shows classification of monitoring methods in the conventional monitoring system. As shown in FIG. 43, current general monitoring systems are roughly classified as follows.
(1) System for monitoring “total monitoring device for accumulating alarms” (system described in Non-Patent Document 1, Patent Document 1, Patent Document 2)
In addition to the case where a general monitoring device is not used,
(2) A system that monitors “monitored devices that generate alarms with screens that appeal to the eyes and alarms that generate voices that appeal to the ears” (3) “monitored that generates alarms with screens that appeal to the eyes but does not generate sound alarms” System to monitor (4) System to monitor (monitored device that does not generate alarm by sound that appeals to the eyes but emits sound alarm) (5) “Monitors the monitored object, and the change in state is an alarm A system that allows the observer to determine whether or not it is present "
It is divided into five.

  By using the monitoring device according to the embodiment of the present invention, the monitoring person generates an alarm without modifying the integrated monitoring device or the monitored device itself as shown in (1) to (5). Therefore, it is possible to intuitively set the determination condition. In addition, the monitor can set so that an alarm including desired information is output when the determination condition is satisfied.

  FIG. 1 is a schematic diagram of the configuration of a monitoring device 100 and peripheral devices thereof according to an embodiment of the present invention.

  The monitoring device 100 is configured by hardware constituting a general-purpose PC having, for example, a CPU, a RAM, a ROM, an HDD, and the like, and images from a monitored device and a monitoring target are transmitted via the VGA-USB converter 110 and the like. Receive a signal. In addition, the monitoring device 100 receives an audio signal from the monitored device or the monitoring target via the microphone 120. In addition, the monitoring device 100 receives an input from a supervisor through an input device such as a keyboard, a mouse, or a touch panel.

  The monitor uses the monitoring device 100 to speak information included in the received signal (if the signal is a video, characters and / or colors included in a predetermined area of the screen, and if the signal is a voice, It is possible to set a judgment condition regarding the message content or sound characteristics. In addition, the monitor can set the content of the alarm that is output through the monitor 130 or the speaker 140 connected to the monitoring device 100 when the determination condition is satisfied. The alarm is output by a character string and its background color and sound. The monitor can set what kind of alarm is output together with the setting of the determination condition. FIG. 4 is a flowchart showing a flow of setting the above-described determination condition and alarm output. Details will be described later.

  In addition, the monitoring device 100 can communicate with another monitoring device via USB or a network, and can receive a signal output from another simple device. The content of the signal is a status indicating the status of the monitored device monitored by the monitoring device (device number of the monitoring device + output number (a number that can be set by the monitor with respect to the determination condition)) (hereinafter, “ Judgment signal "). In addition, when the alarm state is released, a release flag is included in the determination signal in order to notify other monitoring devices that the alarm has been released. In FIG. 1, the flow of the determination signal is represented by a dashed arrow.

  The monitoring apparatus 100 that has received the determination signal further sets a determination condition using the apparatus number and the output number included in the determination signal, and outputs an alarm having a predetermined content when the determination condition is satisfied. It can be configured as follows. The monitor can set the determination condition and the alarm for the determination signal in the same manner as the determination condition and the alarm that are set for the signal from the monitored device. FIG. 5 is a flowchart showing a flow of setting determination conditions and alarm output based on a determination signal. Details will be described later.

  Hereinafter, in order to avoid confusion, a determination condition set for a signal from the monitored apparatus is referred to as a “first determination condition”, and a determination condition set for the determination signal is referred to as a “second determination condition”. . A monitoring device that performs determination based on the first determination condition, outputs an alarm, and transmits a determination signal to another monitoring device is expressed as “monitoring device 100A”. A monitoring device that receives a determination signal transmitted from one or more monitoring devices 100A, makes a determination based on the second determination condition, and outputs an alarm is expressed as “monitoring device 100B”.

  Here, the monitoring device 100A and the monitoring device 100B are merely distinguished for the sake of explanation, and in fact, one monitoring device 100 is assumed to be one of the monitoring devices 100A and 100B depending on the purpose of use. It can be arbitrarily configured to operate.

  The VGA-USB converter 110 receives a video signal in a monitoring state displayed on a display by a monitored device or a monitoring target using a VGA or the like, and converts the video signal into a USB signal or the like so that the PC can read the video signal. USB is merely an example, and may be converted into an Ethernet (registered trademark) signal or the like. The video signal is input to the monitoring apparatus 100 through an interface such as USB.

  The microphone 120 detects the sound output from the monitored device or the like through an air signal and converts it into an analog electric signal. The analog electrical signal is input to the monitoring device 100. Note that the microphone 120 is not necessary when an analog signal can be input as an electrical signal from a monitored device or the like.

  The monitor 130 is a display device connected to the PC body, such as a liquid crystal display or a CRT, and receives a video signal output from the monitoring device 100. The monitor 130 notifies the user of an alarm expressed by characters and colors.

  The speaker 140 receives the audio signal output from the monitoring device 100 and notifies the user of an alarm expressed by sound.

  In the above example, the monitoring device 100 is described separately from the VGA-USB converter 110, the microphone 120, the monitor 130, and the speaker 140, but is not limited to this example. For example, the VGA-USB converter 110, the monitor 130, or the speaker 140 may be provided as the same hardware as the monitoring device 100.

  In the example of FIG. 1, the monitoring device 100 has been described as being configured using a general-purpose PC. However, the monitoring device 100 has dedicated hardware that can exhibit the functions described below to the minimum. May be used.

<Example of monitoring apparatus 100A having an alarm output function>
FIG. 2 shows a usage example of the monitoring apparatus 100A according to the embodiment of the present invention. First, FIG. 2A shows a normal monitoring system. A monitor and a speaker representing information from the monitored device and the monitoring target exist in the monitoring room.

  On the other hand, FIG. 2B shows an example in which the monitoring apparatus 100 is connected. First, a video in a monitoring state output from the monitored device 200 (or a monitoring target) is input to the video distributor 210. The video distributor 210 distributes the monitored device and the video to be monitored. The distributed video is displayed on the display 220. Similarly, for the sound, the output from the monitored device is distributed and input to the monitoring device 100.

  The monitoring device receives the signal and captures it. Then, the monitoring apparatus 100 applies the determination condition set by the monitor to the captured signal. As a result, the monitoring apparatus 100 outputs an alarm to be notified to the display 130 or the speaker 140.

<Example of monitoring device 100B having a judgment signal monitoring function>
3 receives determination signals from the plurality of monitoring devices 100A-1,..., 100A-N described above, applies the second determination condition to the contents of the determination signals, and the conditions are satisfied. In this case, the usage example of the monitoring device 100B that outputs a predetermined alarm is shown. Each monitoring device 100 may be configured not to include an input device for the monitor, a monitor, and a speaker, and exclusively transmit a determination signal to the monitoring device 100B.

  The monitoring device 100A and the monitoring device 100B can be connected by any means such as a USB or Ethernet network.

<2. Function>
Next, functional blocks of the monitoring apparatus 100 according to an embodiment of the present invention will be described with reference to FIG. FIG. 6 shows elements particularly relevant to the description of the present embodiment among various elements included in these apparatuses.

  In the following, as described above, the signal is determined based on the first determination condition, the alarm output function (example of the monitoring device 100A) that outputs the alarm and the determination signal, and the second determination condition for the determination signal. A determination signal monitoring function (an example of the monitoring device 100B) that makes a determination based on this and outputs an alarm will be described. In the following, for the sake of simplicity, the description will be made assuming that only the video signal is output from the monitored device unless otherwise specified.

<2.1 Alarm output function>
The monitoring apparatus 100A according to an embodiment of the present invention includes a determination condition setting unit 601, a storage unit 602, a first determination unit 603, a video signal capturing unit 604, a video signal analyzing unit 605, and an audio signal capturing. Unit 606, audio signal analysis unit 607, determination result output unit 608, and determination signal transmission unit 609.

  The determination condition setting unit 601 accepts settings for the first determination condition, alarm output, and determination signal through the GUI from the supervisor, and stores the contents in the storage unit 602 described later. The setting procedure by the supervisor is as shown in FIG. Here, this procedure will be described using a specific GUI example.

  FIG. 7 is an example of a GUI screen in which the monitor determines an area (corresponding to step S <b> 401 in FIG. 4) to be determined by the first determination condition. A monitor is captured by the monitoring apparatus 100A and displayed on the screen freehand as indicated by a in the figure, or “freely determined in size as indicated by b, c, d in the figure. The area can be defined by a "movable" figure (eg, a square or a circle). A region surrounded by the frame is a determination part. Note that a, b, c, and d are area IDs 700 and are used to identify the areas.

  The determination condition setting unit 601 recognizes the region designation by the supervisor, and stores information on this region as region information 651 in the storage unit 602 by an arbitrary method. An example of a table for storing the area information 651 is shown in FIG. In the example of FIG. 10, each area is represented by pixel coordinates on the display screen. For example, the area identified by the area ID “a” is the points (256, 550), (258, 548), (260, 549),..., (254, 560), (256, 550) on the screen. ). Here, the line connecting the points is a straight line. However, the coordinate designation method for specifying the area on the screen is not limited to this example, and can be arbitrarily designated.

  In addition, information indicating the frame color of each area is stored in the item “frame color”. Here, the RGB value represented by a decimal number is used as a method of representing “frame color”, but is not limited thereto. Other information included in the area information 651 in FIG. 10 will be described later.

FIG. 8 is a GUI screen for setting a determination condition (first determination condition) for each area after the setting of the area is completed (corresponding to step S402 in FIG. 4). In order to specify a region ID 700, a frame color 802, a determination type 804 (character determination, color determination, character + color determination, no setting) to be applied to information in the frame, and a color on the screen A dropper 806 to be used and a color condition 810 used for color determination are included. Here, items that can be selected as determination types are described below.
-Character judgment: Characters (character strings) included in the area are used as judgment conditions. A character string designated as a condition is set on a GUI screen described later.
-Color determination: The color included in the area is set as the determination condition. The color specified for the condition is specified by the color condition 810 on the GUI screen. -Character + color determination: Use a combination of character determination and color determination-No setting: Information contained in this area is used for the determination condition In addition, when the monitor designates a color as the color condition 810, the monitor can set it through the color wheel designation screen 808. At this time, the hue range (degrees) can be set in order to give a certain width to the designated color.

The determination condition setting unit 601 recognizes the input content by the supervisor, and stores information on this region as region information 651 in the storage unit 602 by an arbitrary method. An example of a table for storing the area information 651 is shown in FIG. Items set through the screen of FIG. 8 are as follows.
-Determination processing: Character determination, color determination, character + color determination, information without setting is stored-Color 1 to Color 4: The specified color is stored as a decimal RGB value-Color 1 range to Color 4 Range: The hue range to give the specified color width is expressed in degrees.

  Note that the colors (RGB values) that are included in the condition by specifying the hue range (degrees) can be obtained by calculation when the first determination unit 603 described later performs the condition determination. Alternatively, when a hue is designated through the screen, such calculation may be performed and the color (RGB value) may be stored. In such a case, a plurality of RGB values, which are color information included in the “color range”, may be further stored as additional items of the area information 651. In the above example, the maximum number of colors and color ranges specified is four, but fewer or more types of colors and color ranges may be specified.

  FIG. 9 is an example of a GUI screen for setting the determination condition (first determination condition) for the set area and the content of the alarm output and the content of the determination signal when the condition is satisfied (step S403 in FIG. 4). , Corresponding to S404). Using the screen, the monitor uses the conditional expression 900, the output sound 902, the output character string 904, the background color 906, the output number 908 included in the determination signal, and the monitoring device 100A included in the determination signal. Device number 910 can be set.

  In the conditional expression 900, a conditional expression is input by combining the designation of “character determination” and “color determination” for each region ID set in FIG. The expression format of the logical operation symbol is arbitrary. For example, “+” may be used as the “or” condition, and “*” may be used as the “and” condition.

  In the case of “character determination”, the conditional expression is described by a region ID followed by a keyword surrounded by {}. For example, “a {(Kochi) + (Takamatsu)}” represents that a character string “Kochi” or “Takamatsu” appears in the area a.

  In the case of “color determination”, the conditional expression is described by an area ID followed by a numerical value. For example, “c1” means a condition that the color specified by “Color 1” (or a color in a range specified by “Hue range”) is included in the region c.

  The output sound 902 represents an arbitrary audio file that is output when the conditional expression is satisfied. When a plurality of conditional expressions are satisfied at the same time, for example, it is configured to output in order from the top. In the example of FIG. 9, output is performed in the order of “chime part 1”, “chime part 2”, and “chime part 3”.

  The output character string 904 is a character string output by the monitoring apparatus 100A. If blank, nothing is displayed.

  A background color 906 represents the background color of the character string output by the monitoring apparatus 100A. The background color is set by selecting from the prepared colors using the “display color selection” window or by specifying the components of each RGB color. In the example of FIG. 9, yellow is designated.

  The output number 908 is a number used as an identifier for specifying the condition in the monitoring apparatus 100A. The output number 908 is included in the determination signal when the first determination unit 603 of the monitoring apparatus 100A described later determines that the condition is satisfied, and is transmitted to the other monitoring apparatus 100B. When “0” is designated as the output number 908, the determination signal is not transmitted to the other monitoring apparatus 100B even if the condition is satisfied.

  The device number 910 is used to identify the monitoring device 100A. The device number 910 is included in the determination signal together with the output number 908 described above when the determination signal is transmitted to the other monitoring device 100B.

The determination condition setting unit 601 stores the above-mentioned contents designated by the supervisor in the first determination condition 652 and the device number 653. An example of a table that stores the first determination condition 652 is shown in FIG. Each item is described below.
-ID: Sequence number automatically assigned to each entry-Conditional expression: Conditional expression applied to each area-Output sound: Sound file output when the condition is satisfied-Output character string: Condition Character string that is output when the condition is satisfied-Background color: Background color that is output when the condition is satisfied-Output number: Included in the determination signal that notifies other monitoring devices that the condition is satisfied Number for identifying the condition-occurrence state: A flag indicating that the condition is satisfied Note that the designated device number is stored as the device number 653.

  FIG. 15 shows an output by the determination result output unit 608 described later when the conditions of ID “1” and “2” are satisfied and the condition of ID “3” is not satisfied among the conditions shown in FIG. The example of the screen to be displayed is shown (corresponding to step S405 in FIG. 4). At the same time as the screen, “Chime part 1.wav” set as the output sound is output, and then “Chime part 2.wav” is output.

  The above example is an example when the signal output from the monitored device is a video signal. On the other hand, when the signal output from the monitored apparatus is an audio signal, the area information shown in FIG. 10 is not necessary. In addition, the conditional expression 900 illustrated in FIG. 11 can be described in a format that does not include an area ID, for example, “(Kochi) + (Kagawa)”. Thus, the condition is satisfied when the voice message included in the voice signal includes the utterance content “Kochi” or “Kagawa”. As another example of the conditional expression 900, an audio file may be designated, for example, “alarm sound of monitored apparatus A.wav”. Thus, the condition is satisfied when the audio signal is the same as a known audio signal emitted from the monitored apparatus A. The output sound 902, the output character string 904, the background color 906, the output number 908, and the generation state 912 are the same as in the case of the video signal.

  As described above, the storage unit 602 stores the area information 651, the first determination condition 652, and the device number 653. The determination signal information 654 and the second determination condition 655 will be described later.

  The first determination unit 603 determines whether information included in a signal input from the monitored device satisfies a condition (first determination condition) designated by the monitor through FIGS. 7-9. When the input signal is a video signal, the first determination unit 603 captures the video signal through the video signal capture unit 604 described later. Next, the first determination unit 603 causes the video signal analysis unit 605 described later to acquire character or color information included in the area specified by the area information 651 in the captured video. Then, the first determination unit 603 refers to the first determination condition 652 and determines whether the condition is satisfied.

  On the other hand, when the input signal is an audio signal, the first determination unit 603 acquires the audio signal through an audio signal acquisition unit 606 described later. Next, the 1st determination part 603 makes the audio | voice signal information analysis part 605 mentioned later acquire the content of the audio | voice represented by the taken-in audio | voice. Then, the first determination unit 603 refers to the first determination condition 652 and determines whether the condition is satisfied. Alternatively, the first determination unit 603 compares the acquired audio waveform (spectrum) with the audio waveform of the audio file specified by the first determination condition 652 to determine whether the condition is satisfied. Since the technique for comparing two speech waveforms is known, a description thereof is omitted here.

  When a certain condition is satisfied, the first determination unit 603 sets the “occurrence state” item to “1” in the first determination condition 652 of FIG. 11. If the condition is not satisfied as a result of the subsequent determination, the “occurrence state” item is set to “0”.

  The video signal capturing unit 604 captures a video signal transmitted from the monitored device.

  The video signal analysis unit 605 analyzes the video signal and acquires character or color information included in the area specified by the area of the area information 651. The characters are obtained, for example, using known OCR techniques.

  The audio signal capturing unit 606 captures an audio signal transmitted from the monitored device.

  The voice signal analysis unit 607 analyzes the voice signal and acquires the content of the voice message included in the voice signal. The content of the voice message is acquired using, for example, a known voice recognition technique.

  The determination result output unit 608 outputs an output sound and an output character string corresponding to the condition determined by the first determination unit 603 to be satisfied, to the monitor 102 and the speaker 104.

  The determination signal transmission unit 609 configures a determination signal using the output number corresponding to the condition determined by the first determination unit 603 to be satisfied and the device number of the monitoring device 100A. Then, the determination signal is transmitted to the other monitoring device 100B.

  A configuration example of the determination signal is shown in FIG. FIG. 12A illustrates an example of a configuration of a determination signal that is transmitted to the other monitoring device 100B when the conditions of the output numbers 1 and 2 are satisfied, for example. Here, the device number “1” of the monitoring device 100A set by the monitor through the screen 9 and the output numbers “1” and “2” corresponding to the satisfied conditions are designated.

  On the other hand, if the condition is no longer satisfied by further determination by the first determination unit 603, as shown in FIG. 12B, the determination signal to which the “release flag” is attached is again sent to another It is transmitted to the monitoring device 100B. Here, the information “1” is included as the “release flag”, but what information is used as the “release flag” can be arbitrarily determined.

  FIG. 13 is a flowchart showing processing of the monitoring apparatus 100A that takes in a video signal and outputs an alarm when the condition is satisfied. The process shown in FIG. 13 is repeatedly executed at regular intervals.

  In step S1301, the video capturing unit 604 captures a video signal input from the monitored device.

  In step S1302, the first determination unit 603 reads the area information 651 in the storage unit 602.

  In step S1303, the video information analysis unit 605 acquires information included in the area specified by the area information 651 from the video signal.

  In step S1304, the first determination unit 603 reads the first determination condition 652 in the storage unit 602.

  In step S1305, when the “occurrence state” of the condition read from the first determination condition 652 is “0” (that is, when the condition is not satisfied), the process proceeds to step S1306. The first determination unit 603 determines whether the character string and / or color acquired in step S1303 satisfies the condition read in step S1304.

  If the result of determination in step S1306 is that the condition is met, processing proceeds to step S1307, and the “occurrence state” item of the first determination condition 652 (FIG. 11) is set to “1”.

  On the other hand, if it is determined in step S1306 that the condition is not satisfied, the process ends.

  In step S1308, the determination result output unit 608 outputs the output sound and the output character string designated by the first determination condition 652 (FIG. 11) to the monitor 102 and the speaker 104.

  In step S1309, the determination signal transmission unit 609 transmits a determination signal (FIG. 12A) including the output number specified by the first determination condition 652 (FIG. 11) and the device number 653 of the monitoring device 100A. The determination signal is transmitted to the other monitoring device 100B.

  On the other hand, if the “occurrence state” of the condition read from the first determination condition 652 is “1” in step S1305 described above (that is, the condition is satisfied), the process proceeds to step S1310. The first determination unit 603 determines whether the character string and / or color acquired in step S1303 continues to satisfy the condition read in step S1304.

  If it is determined in step S1310 that the condition is still satisfied, the process ends.

  On the other hand, if it is determined in step S1310 that the condition is not satisfied, the process advances to step S1311 to set the “occurrence state” item of the first determination condition 652 (FIG. 11) to “0”.

  In step S1312, the determination result output unit 608 stops outputting the output sound and the output character string specified by the first determination condition 652 (FIG. 11).

  In step S1313, the determination signal transmission unit 609 determines a determination signal (FIG. 12B including the output number designated by the first determination condition 652 (FIG. 11), the device number 653 of the monitoring device 100A, and the release flag. )), And transmits the determination signal to the other monitoring device 100B.

  FIG. 14 is a flowchart showing processing of the monitoring apparatus 100A that takes in an audio signal and outputs an alarm when the condition is satisfied. Unlike the case of capturing a video signal shown in FIG. 13, the audio signal capturing unit 606 captures an audio signal (step S1401). Here, the first determination unit 603 does not need to read the area information 651, and the audio signal analysis unit 607 acquires the content of the audio message from the audio signal (step S1402). The subsequent processing is the same as the processing shown in FIG.

  Through the above processing, the monitoring device 100A according to an embodiment of the present invention captures video or audio signals output from existing monitored devices, and information included in these signals is arbitrarily set by the monitor. When the condition is satisfied, predetermined information can be output. In particular, the supervisor sets a monitoring area for an image signal output from an existing monitored device through an intuitive GUI screen, and generates a desired alarm when a desired condition is satisfied. Can do. As a result, a desired alarm can be generated without any modification to the monitored apparatus.

<2.2 Judgment signal monitoring function>
As described above, the monitoring apparatus that takes in the output from the monitored apparatus, outputs an alarm based on the determination condition (first determination condition) set by the supervisor, and simultaneously transmits a determination signal indicating the content of the alarm. The function of 100A has been described. In the following, it is possible to receive a determination signal transmitted from such a monitoring apparatus 100A and output a further alarm based on a determination condition (second determination condition) set for the content of the determination signal. The function of the monitoring device 100B will be described.

  FIG. 16 is a diagram illustrating a connection configuration between the monitoring device 100B and the monitoring device 100A that receives video signals from the monitored devices. Here, as an example, four monitoring devices 100A-1 to 100A-4 are described. Each monitoring device 100A outputs an alarm and transmits a corresponding determination signal in accordance with the first determination condition 652 set by the monitor. The monitoring apparatus 100B can receive this determination signal and output a further alarm.

  The monitoring device 100B according to the embodiment of the present invention further includes a determination signal receiving unit 610 and a second determination unit 611 in addition to the functional blocks provided in the monitoring device 100A. In addition, the storage unit 602 that has already been described further stores determination signal information 654 and a second determination condition 655.

  The above-described determination condition setting unit 601 further receives a setting for the second determination condition from the monitor through the GUI, and stores the content in the storage unit 602. The procedure for setting by the supervisor is shown in FIG. The procedure will be described using a specific GUI example.

  FIG. 17 shows a GUI screen for setting a conditional expression 1600 for evaluating a determination signal transmitted from the monitoring apparatus 100A, an output sound 1602 output when the condition is satisfied, an output character string 1604, and a background color 1606. (Corresponding to steps S501 and S502 in FIG. 5). Unlike the GUI screen of FIG. 9, the supervisor sets conditions using conditional expressions of different formats.

  Here, the supervisor describes the conditional expression by the device number and the output number included in the determination signal transmitted from each monitoring device 100A. The logical operation method is the same as in FIG. In FIG. 17, “1-10” included in the conditional expression represents an alarm with the output number “10” of the development device with the device number “1”.

  The point that the sound, the character string, and the background color are output when the condition is satisfied is similar to the example described in FIG. Note that, unlike the case of FIG. 9, the supervisor does not need to specify the output number and the device number.

  The determination condition setting unit 601 recognizes the input content by the supervisor using the GUI screen of FIG. 17, and stores these pieces of information in the second determination condition 655 illustrated in FIG.

  FIG. 21 illustrates an example of a screen output by the determination result output unit 608 described above when the conditions of ID “1” and “2” are satisfied among the conditions illustrated in FIG. 5 corresponds to step S503). At the same time as the screen, “Chime part 1.wav” set as the output sound is output, and then “Chime part 2.wav” is output.

  The determination signal receiving unit 610 receives a determination signal (see FIG. 12 for the configuration) transmitted from the other monitoring device 100A, and stores the content in the determination signal information 654 of the storage unit 602. FIG. 19 is an example of a table that stores such determination signal information 654. The example of FIG. 19 indicates that a determination signal including the output number “2, 8, 10” has been received from the monitoring device 100A having the device number “1”. Furthermore, it can be seen that the determination signal is also received from other monitoring devices.

  When the determination signal receiving unit 610 receives a determination signal transmitted when the condition is satisfied, as shown in FIG. 12A, the determination signal receiving unit 610 determines the device number and the output number included in the determination signal as shown in FIG. Store in the signal information 654. On the other hand, when the determination signal receiving unit 610 receives the determination signal transmitted when the condition is not satisfied as shown in FIG. 12B, the determination signal receiving unit 610 deletes the corresponding item stored in FIG.

  22A to 22C are diagrams illustrating such changes in the determination signal information 654. FIG. First, it is assumed that the determination signal information 654 is as shown in FIG. Next, when the determination signal receiving unit 610 receives the determination signal “device number = 3, output number = 8”, the determination signal information 654 is updated as shown in FIG. Furthermore, when the determination signal receiving unit 610 receives a determination signal of “device number = 1, output number 2, 10, release flag = 1”, the corresponding item is deleted as shown in FIG. The

  The second determination unit 611 determines whether the determination signal information 654 stored in the storage unit 602 satisfies the condition (second determination condition) specified by the supervisor through FIG. When the condition is satisfied, the second determination unit 611 sets the item “occurrence state” to “1” in the second determination condition 655 of FIG. 18. If the condition is not satisfied as a result of the subsequent determination, the “occurrence state” item is set to “0”.

  The determination result output unit 608 described above further outputs an output sound and an output character string corresponding to the condition determined by the second determination unit 611 to be satisfied, to the monitor 102 and the speaker 104.

  FIG. 20 is a flowchart showing the process of the monitoring apparatus 100B that outputs an alarm when a determination signal is received from the other monitoring apparatus 100A and the condition is satisfied.

  In step S2001, the determination signal receiving unit 610 receives a determination signal transmitted from another monitoring apparatus 100A.

  In step S2002, the determination signal receiving unit 610 stores the content of the received determination signal in the determination signal information 654. Here, when the determination signal includes a release flag, the corresponding item is deleted from the determination signal information 654.

  In step S2003, the second determination unit 611 reads the second determination condition 655 in the storage unit 602.

  In step S2004, when the “occurrence state” of the condition read from the second determination condition 655 is “0” (that is, when the condition is not satisfied), the process proceeds to step S2005. Then, the second determination unit 611 determines whether the determination signal information 654 updated in step S2002 satisfies the condition read in step S2003.

  If the result of determination in step S2005 is that the condition is met, processing proceeds to step S2006 and the item “occurrence state” in the second determination condition 655 (FIG. 18) is set to “1”.

  On the other hand, if it is determined in step S2005 that the condition is not satisfied, the process ends.

  In step S2007, the determination result output unit 608 outputs the output sound and output character string specified by the second determination condition 655 (FIG. 18) to the monitor 102 and the speaker 104, and ends the process.

  On the other hand, in the above-described step S2004, when the “occurrence state” of the condition read from the second determination condition 655 is “1” (that is, the condition that the condition is already satisfied and the alarm is being output is If the condition is satisfied continuously, the process proceeds to step S2008. Then, the second determination unit 611 determines whether the determination signal information 654 updated in step S2002 satisfies the condition read in step S2003.

  If it is determined in step S2008 that the condition is still satisfied, the process ends.

  On the other hand, if it is determined in step S2008 that the condition is not satisfied, the process proceeds to step S2009, and the item “occurrence state” in the second determination condition 655 (FIG. 18) is set to “1”.

  In step S2010, the determination result output unit 608 stops outputting the output sound and the output character string specified by the second determination condition 655 (FIG. 18), and ends the process.

  Through the above processing, the monitoring device 100B according to the embodiment of the present invention can output further alarms according to the alarm generation state of the plurality of monitoring devices 100A that monitor the output of the monitored device. The monitoring device 100B needs to be hardware capable of inputting a plurality of determination signals. However, as described above, the hardware of the monitoring device 100A and the monitoring device 100B can be the same. In this case, for example, when the necessary number changes after the introduction of the monitoring device 100A and the monitoring device 100B, the hardware is the same, so that the monitoring device 100A and the development device 100B can be diverted. It becomes.

  Examples of further configurations of the monitoring device 100B described above are shown in FIGS. FIG. 22 illustrates an example in which the monitoring device 100B receives a determination signal transmitted by the monitoring device 100A that takes in only an audio signal from the monitored device. FIG. 24 shows an example in which the monitoring apparatus 100B that receives the determination signal further receives an image directly from the monitored apparatus and the like and outputs an alarm based on the first determination condition 652, similar to the monitoring apparatus 100A. Represents. Such a configuration is also possible when the monitoring device 100B has a sufficiently high calculation processing capability.

  The above-described functions of the monitoring devices 100A and 100B according to the embodiment of the present invention are not intended to be monitored by anyone, that is, including devices that do not have an alarm function. All screens that have a fixed display and color position to be read are displayed as monitored devices in the screen output without any modification to the monitored device. The alarm generation conditions can be flexibly and integratedly set and monitored.

  In addition, since this monitoring device distributes and uses the audio output and screen output of the monitored device, when the monitored device main body and the attached monitor or speaker are located at a distance, it is close to the monitored device main body. Even if there is no installation space, it can be installed near the attached monitor or speaker, and therefore the installation location is flexible.

  Furthermore, a plurality of different monitored devices and screen output and audio output of the monitoring target can be integratedly monitored to generate a complex alarm that cannot be obtained from the monitored device alone.

<3. Example of operation>
Below, the specific example of operation | movement of the monitoring apparatus 100 in one Embodiment of this invention is demonstrated. Here, an example of the monitoring device 100A (described in the following section 3.1) that performs determination on a video signal transmitted from a monitored device and outputs an alarm and a determination signal, and determination on the determination signal are performed. This will be described separately with an example of the monitoring device 100B that performs and outputs an alarm (described in the following section 3.2).

<3.1 Alarm output function>
<Example when the monitored device is a video titler>
First, an example in which the monitoring device 100A according to an embodiment of the present invention monitors a video signal output from the monitored device “moving image titler” will be described with reference to FIGS. A video titler is a device that stores video files in a storage medium such as an HDD, and allows a user to select an arbitrary video and reproduce it as a video. As shown in FIG. 25, this apparatus outputs a GUI screen for displaying the file name of the selected moving image, but does not have a function of generating an alarm itself (corresponding to (5) in FIG. 43).

Even if it is a device that is not supposed to be monitored by such a person, if it is a device that can output a GUI screen, the monitoring device 100A can generate an alarm in an easy-to-understand manner for the supervisor. I can tell you. The animation titler GUI screen will be described using the numbers shown in FIG.
-1: List of video files that can be selected. Select a video from here. When a video is selected at -2: 1 and then the standby button is pressed, the video is put on standby and ready for playback. -3: The standby video is displayed. Nothing is displayed when there is no standby video. -4: When the TAKE button is pressed, the standby video is played and output from the video / audio output terminal attached to the video titler.

  FIG. 26 shows a GUI screen (corresponding to FIG. 7) for designating a region to be determined in the video signal output by the moving image titler in the monitoring apparatus 100A. The video signal capturing unit 604 of the monitoring device 100A captures a screen of a moving image titler that is a monitored device at regular intervals. Therefore, the same image as the screen output by the video titler is displayed on the monitoring device 100A. Since the monitoring apparatus 100A captures the entire screen output by the moving image titler, the clock and window displayed in the moving image titler are also captured as they are.

The areas a, b, and c designated in FIG. 26 are areas designated by the monitor through the determination condition setting unit 601 of the monitoring apparatus 100A. As already described, the video signal analysis unit 605 of the monitoring apparatus 100A acquires the “character string” and / or “color” inside these areas, and according to the first determination condition specified by the monitor. Make a decision. Here, it is assumed that the following area information is set.
-Area a: Character determination Reads characters of captured image by OCR-Area b: Color determination Determines color of captured image-Area c: Character determination Reads characters of captured image by OCR An example of information input to the GUI screen by the person is shown in FIG. 27 (corresponding to the GUI screen of FIG. 8).

  In addition, in OCR, there is a possibility of erroneously recognizing characters, but in general, when reading characters on a PC screen, the accuracy of OCR is improved compared to recognition of handwritten characters. In particular, if a monitoring target such as a video titler or a font used in a monitored device is designated as OCR, the occurrence of erroneous recognition can be suppressed to a level that is practically acceptable.

  Next, an example of the first determination condition input to the GUI screen by the supervisor is shown in FIG. 28 (corresponding to the GUI screen of FIG. 9). For example, if you need to play a video called “845OP” at 20:45, and a video called “745OP” at 7:45, the video titler operator will play each video before the scheduled playback time. Stand by. Here, an alarm is output if the standby video is mistaken, such as when “845OP” is on standby when the OS clock is at 7 o'clock (FIG. 29). Thereby, it is possible to prevent mistakes in the standby video.

  In this way, it is possible to easily and flexibly meet the demands of the supervisor without modifying the moving image titler itself and without modifying the PC body.

<Example when monitored device is P-wave display PC>
Next, an example in which the monitoring device 100A according to the embodiment of the present invention monitors the video signal output from the monitored device “P-wave display PC” will be described with reference to FIGS. The P-wave display PC is a P-wave display that displays the epicenter, magnitude, seismic intensity of each location, and predicted arrivals in a constantly moving figure based on the observation information of the weak shaking observed just before the full-scale earthquake. It is a personal computer.

The output screen of the P-wave display PC will be described with reference to FIG. 30 and using the numbers shown in the drawing.
1: A map of Japan is displayed.
2: When a P wave is observed, a circle of a predetermined color spreads around the epicenter. The place filled with a circle indicates that an earthquake has arrived, and spreads in real time. 3: The observed magnitude and seismic intensity are displayed. The color in the frame for displaying the magnitude and seismic intensity changes according to the size. 4: The area where the earthquake was actually observed and the seismic intensity of each area are displayed.
The P-wave display PC does not alert with sound, but can be said to be a device that can generate an alarm by changing the color according to the magnitude and seismic intensity (corresponding to the example of (3) in FIG. 43).

  FIG. 31 shows a GUI screen for the monitor to specify an area to be determined using the monitoring apparatus 100A (corresponding to FIG. 7). Here, it is assumed that the areas a, b, and c in FIG. 31 are set. Region a is color determination, region b is character determination, and region c is color determination. A region information setting screen is shown in FIG.

  At this time, the supervisor sets a first determination condition using a conditional expression as shown in FIG. 33, so that the vicinity of Shikoku (conditional expression b {(Matsuyama) + (Kochi) + (Tokushima) + (Takamatsu) )}) Earthquake (c1) or when a large earthquake is predicted (conditional expression a1), a desired alarm can be output. FIG. 34 shows an example of an alarm output screen that is output when “conditional expression b {(Matsuyama) + (Kochi) + (Tokushima) + (Takamatsu)} * c1]” is satisfied.

<Example when the monitored device is a general monitoring device>
Next, an example in which the monitoring device 100A according to the embodiment of the present invention monitors a video signal output from an “integrated monitoring device” that is a monitored device will be described with reference to FIGS. As described above, the “integrated monitoring device” described here is a device that operates in the mode of FIG.

  The output screen of the integrated monitoring apparatus will be described with reference to FIG. Normally, nothing is displayed on the screen, and when an alarm occurs, what kind of alarm has occurred in which device is displayed in a rectangle of a predetermined size. The type of alarm sound is one type of beep sound, and is configured to be played when an alarm occurs.

  FIG. 36 displays an example of a GUI screen (corresponding to FIG. 7) for determining a determination target area in the monitoring apparatus 100A. In FIG. 36, a portion surrounded by a colored frame is subjected to any one of “character determination”, “color determination”, and “character + color determination”. An alarm is output when the characters and colors output on the screen meet the conditions set later.

  As described above, the alarm sound can be arbitrarily set by setting the monitoring apparatus 100A. As a result, for example, when a failure of a certain monitoring target A occurs frequently, the monitoring target B to the monitoring target F connected to the monitoring target A also “communicate with the device A” when the monitoring target A generates an alarm. When an alarm “not possible” occurs, a conditional expression is added, and it can be set afterwards to generate a voice alarm “possibility of device A failure”. When the failure of the monitoring target A is recovered, the conditional expression can be deleted.

  As described above, by setting the determination condition and the output alarm using the monitoring apparatus 100A, the conditional expression for generating the alarm is flexibly set every time, for example, when it is desired to temporarily monitor a specific device. be able to. Further, even if the number of related monitoring devices continues to increase after the introduction of the comprehensive monitoring device, it can be dealt with by changing the setting on the monitoring device 100A.

  In the present embodiment, as an example of the screen of the integrated monitoring apparatus, an example as shown in FIG. 35 is given. For example, as shown in FIGS. 37 (A) to (D), colors and characters are used. If the place where the alarm is notified is constant, the present invention can be applied.

<Example when the monitored device is a radar rainfall display PC>
Next, an example in which the monitoring device 100A according to an embodiment of the present invention monitors a video signal output from a “radar rainfall display PC” that is a monitored device will be described with reference to FIGS. As shown in FIG. 381, the radar rainfall display PC is a device that represents the rainfall by painting the points where rain was observed on the map with different colors from blue to red according to the strength of the rainfall. It is. Data is updated and rewritten every 5 minutes. The radar rainfall display PC does not have an alarm generating function (that is, corresponds to the example of FIG. 43 (5)).

  FIG. 39 shows a GUI screen (corresponding to FIG. 7) for the monitor to determine a determination target area in the monitoring apparatus 100A. For example, an area a (color determination) can be set, and a voice alarm can be output saying “It has started raining in Ehime” on the condition that blue is included in Ehime Prefecture, that is, area a. Further, on condition that red is included in the area a, it is possible to output an audio alarm saying that heavy rain has started to fall in Atago. Furthermore, a voice alarm may be output as “Ehime rain has stopped” on condition that blue or red is no longer included in region a. In this way, it is possible to notify by voice alarm that there is rainfall in Ehime Prefecture.

  As another example, for example, if it is known from experience that if it starts to rain in a place in Kyushu, Shikoku often continues to rain, the place in Kyushu is surrounded by a monitoring frame of the monitoring device, It is also possible to generate an alarm sound indicating the prediction that it will rain in Shikoku.

<3.2 Judgment signal monitoring function>
Next, an example in which the monitoring device 100B according to the embodiment of the present invention monitors the determination signal output from the monitored device will be described with reference to FIGS.

  In the example of FIG. 40, two monitoring device monitoring devices 100A-1 and 100A-2 are used, the monitored device 1 is the “P-wave display PC” described above, and the monitored device 2 is “ Radar rainfall display PC ".

  Here, the monitoring device 100A-1 that monitors the “P-wave display PC” outputs an output number indicating that “an earthquake having a seismic intensity of 3 or more has been confirmed in Ehime”, and at the same time, the “radar rainfall display PC”. When an output number indicating that “there is a region A in Ehime Prefecture where heavy rain is observed” is output from the monitoring device 100A-2 that monitors the earthquake, The monitoring apparatus 100B can output a “land sediment disaster warning in region A” and a voice alarm.

  FIG. 41 illustrates an example in which the monitored apparatus 100A monitors the audio output of the monitored apparatus and the monitored apparatus does not have an audio output terminal. Since the monitored device generates an alarm sound only from the internal speaker, it is impossible to remotely monitor the monitoring device or incorporate the monitored device into the general monitoring device. An example in which the monitoring devices 100A and 100B of the present invention are applied to such a monitored device will be described with reference to FIG.

  For example, a “temperature monitoring device” (not compatible with audio signal output from an external terminal) that emits two different beeps from the device body when the temperature exceeds the temperature set with an external knob is monitored. It is assumed that it is located in a room away from the room. Here, as shown in FIG. 41, a highly directional microphone having a soundproof structure is placed in front of the monitored device, and the output of the microphone is transmitted to the monitoring device 100A. Monitoring device 100A (audio signal capturing unit 606) captures a beep sound output from the monitored device and transmits a determination signal to monitoring device 100B in accordance with a first determination condition set in advance by a monitor. Here, the output number included in the determination signal is set to a different value for each beep sound.

  As a result, a signal output from a device that does not include an external audio output terminal and is not supposed to be monitored at a remote location can be monitored by the monitoring devices 100A and 100B.

  As described above, in addition to the signal output from the monitored device, the monitoring device 100B according to the embodiment of the present invention can further output a desired alarm according to the content of the alarm output from the monitoring device. . This makes it possible to perform integrated monitoring, which has been difficult with the existing method due to factors such as refurbishment of other devices. As an example of integrated monitoring, when it is necessary to monitor a cooling temperature or an air conditioning state in an equipment rack room or the like, a monitoring device 100A-1 connected to a device that emits a beep when the temperature rises, It is conceivable to monitor the monitoring device 100A-2 connected to the device for monitoring the air conditioning in an integrated manner with the monitoring device 100BC. In this case, there is no abnormality in the air conditioning, but it is also possible to obtain complex information such as the temperature rising.
