Description

  The present invention relates to a video recording technique for receiving, recording, and displaying video transmitted over a network, and more particularly to a video imaging control system that performs operation control such as reception, recording, and display of video transmitted over a network.

  2. Description of the Related Art Conventionally, there is a video imaging control system that uses a video recording device that records video with a surveillance camera for the purpose of maintenance and security. A video recording apparatus used for this video imaging control system is required to always operate to record video. Therefore, it is important to prepare a countermeasure when the video recording apparatus cannot record video due to a failure or the like.

  For example, when a video recording device fails, a countermeasure can be considered for promptly repairing or replacing the failed video recording device by notifying a predetermined central management center of the failure. .

  Also, for example, in Patent Document 1 below, a backup video recording device is prepared separately from the video recording device that is normally operating, and when a failure of the video recording device is detected, the backup video is recorded. A technique for recording a video by operating a recording apparatus is disclosed.

  The storage location of video data recorded by the video recording device (recording medium such as a recording tape or hard disk) is a finite resource, and when the recordable capacity of the recording medium decreases due to the recording of video data The video recording apparatus responds by performing processing such as stopping the recording operation or overwriting new information over old information.

In Patent Document 2 below, a plurality of monitoring control target facilities each having a control device to be operated and an instrumentation device for detecting the state of the control target are connected to the Internet line, and through the Internet line, In addition, a monitoring control system for performing remote monitoring and remote operation of each device of these monitoring control target facilities in a service center is disclosed.
JP-A-11-79621 (FIG. 1, paragraph 0012) JP 2004-199211 (FIG. 1)

  However, if a method for notifying a predetermined central management center of a failure or stopping the recording operation when the recordable capacity of the recording medium is reduced is used, a video recording device or a recording medium is used. The video recording cannot be performed until the repair or replacement of the video is performed and the recording of the video data by the video recording apparatus is resumed, so that the requirement of always recording the video is not satisfied.

  On the other hand, the method of operating the backup video recording device when a failure of the video recording device is detected or the method of overwriting old information with new information can record video without interrupting video recording. Is possible. However, it is inefficient to install a backup video recording apparatus that operates only when some failure occurs as a backup. Further, in a large-scale system in which a plurality of video recording apparatuses (for example, several tens) are required to be installed, it is necessary to prepare an expensive backup video recording apparatus for each of the video recording apparatuses. It will be quite expensive. In addition, when the old information is overwritten with the new information, the old information is deleted due to overwriting, and when the old information needs to be confirmed, the information has already been deleted. there is a possibility.

  For example, if the monitoring control system disclosed in Patent Document 2 is used, it is possible to perform remote monitoring and remote operation of a video imaging device provided in a monitoring control target facility.

  Next, functions of the display devices 71 to 73 will be described. Similar to the monitoring cameras 10 to 32 and the video recording devices 41 to 43, the display devices 71 to 73 only have to have the same function, and it is not particularly necessary to provide a special function for a specific display device. Here, the internal configuration of the display device 71 will be described on behalf of the display devices 71 to 73. However, other display devices only have to have the same function, and further have a special function. It may be.

  FIG. 8 is a functional block diagram illustrating an example of the configuration of the display device of the video imaging control system according to the first embodiment of the present invention. The display device 71 shown in FIG. 8 includes at least a video reception unit 711 and a video display unit 712, and further includes a video recording device operation management unit 713 and a video recording device information storage unit 714. Good.

  The video receiving unit 711 has a function of receiving video transmitted from the video recording devices 41 to 43. The video received by the video receiving unit 711 is supplied to the video display unit 712. The video display unit 712 is a monitor that displays the video of the monitoring cameras 10 to 32 received by the video reception unit 711.

  In addition, the video recording device operation management unit 713 has a function of monitoring whether or not the video recording devices 41 to 43 that transmit the video to be received by the video receiving unit 711 are operating normally, and the video recording device 41. It has the function to transmit the information which shows the operating state of -43 to the control apparatus 50. FIG. Furthermore, the video recording device information storage unit 714 stores various information regarding the video recording devices 41 to 43 that are the transmission sources of the video to be received and displayed.

  In the video recording device operation management unit 713 and the video recording device information storage unit 714, the operation for monitoring whether the video recording devices 41 to 43 are operating normally is the monitoring camera operation management unit of the video recording device 41 described above. 414 and monitoring of the operation of the monitoring cameras 10 to 32 in the monitoring camera information storage unit 415 are almost the same. That is, the video recording device operation management unit 713 monitors the operation of the video recording devices 41 to 43 based on information indicating the operating state of the video recording device information stored in the video recording device information storage unit 714, for example. When the video from 41 to 43 cannot be received for a predetermined time or longer, the controller 50 is notified that some trouble has occurred in the video recording devices 41 to 43. The control device 50 can grasp the abnormal operation of the video recording devices 41 to 43 by receiving notification of information indicating that an abnormality has occurred in the operation of the video recording devices 41 to 43 from the display devices 71 to 73. It becomes possible.

  Next, the operation in the first embodiment of the present invention will be described based on the above-described configurations. For example, it is assumed that some trouble occurs in the monitoring camera 12 that captures the vicinity of the door of the room 1002 illustrated in FIG. 2, and the captured image of the monitoring camera 12 cannot be normally recorded / displayed.

  The monitoring camera operation management unit 414 of the video recording device 41 constantly monitors the operating state of the monitoring camera 12 based on the value of the operating state column of the monitoring camera information, for example. The operating state value of the camera 12 increases. Then, the monitoring camera operation management unit 414 determines that the monitoring camera 12 is abnormal when the operating state of the monitoring camera 12 exceeds a predetermined value (for example, “5”), and indicates that the monitoring camera 12 is abnormal. To the control device 50.

  When the operation management unit 502 of the control device 50 receives the operation state notification information indicating the abnormality of the monitoring camera 12 from the video recording device 41 via the communication processing unit 503, the camera information management unit 501 can recover the monitoring camera (that is, recoverable). Inquiries about information regarding the monitoring camera that can supplement the imaging of the imaging location of the monitoring camera 12 in which the failure has occurred are made. The camera information management unit 501 refers to the failure setting information, and identifies identification information (camera number) of the monitoring camera that can recover the monitoring camera 12, a pan position for performing the recovery of the monitoring camera 12, Returns various setting information such as tilt position and zoom magnification.

  For example, as the failure handling setting information when the monitoring camera 12 fails in the installation example shown in FIG. 2, the monitoring camera 11 widens the angle of view (draws an image) and the monitoring camera 13 swings (pans at a constant cycle). It is assumed that it is determined in advance that the imaging location of the surveillance camera 12 is to be captured by performing (Operation). In this case, the operation management unit 502 performs camera information management on the identification information of the monitoring camera 11 and the zoom magnification (a value for ensuring a wide angle of view) of the monitoring camera 11, the identification information of the monitoring camera 13, and the swing instruction. Received from part 501. Here, it is set to recover the imaging of the imaging location of the surveillance camera 12 where the fault has occurred (near the door of the room of the room 1002) by changing the zoom magnification of the surveillance camera 11 and swinging the surveillance camera 13. However, recovery can be performed by arbitrarily combining pan, tilt, zoom, and the like. Here, the recovery is performed by the two monitoring cameras 11 and 13, but the recovery can be performed by only one or three or more monitoring cameras.

  Then, the operation management unit 502 notifies the system control unit 500 of the identification information of the monitoring cameras 11 and 13 received from the camera information management unit 501 and the setting change information thereof, and the system control unit 500 causes the communication processing unit 503 to be notified. To change the setting corresponding to the setting change information to the monitoring cameras 11 and 13. As a result, as shown in FIG. 9, the angle of view of the surveillance camera 11 is widened, and the surveillance camera 11 can image the vicinity of the doors of both the rooms 1001 and 1002 and the surveillance camera 13. By swinging the head and periodically repeating panning, it is possible to alternately image the vicinity of the doors of the rooms of the rooms 1002 and 1003. Note that the control device 50 may control the imaging direction of the monitoring camera 13 by setting the priority to the imaging location by the monitoring camera 13 based on the importance of the imaging location, the arrangement location of the monitoring camera 13, and the like. . That is, not only the surveillance camera 13 is simply swung, but also, for example, the vicinity of the door of the room of the room 1002 can be imaged for 10 seconds and the operation of the area of the door of the room of the room 1003 can be imaged for 20 seconds. Is possible. In addition to the control that the surveillance camera 13 periodically performs the pan operation, the control device 50 can also control the surveillance camera 13 to perform the pan operation irregularly.

  Further, the system control unit 500 of the control device 50 instructs the video recording device 41 to record the video from the monitoring camera 11 as the video of both the monitoring cameras 11 and 12, and from the monitoring camera 13. An instruction is given to record the video as video from both surveillance cameras 12 and 13. In this case, the video recording device 41 records the original surveillance camera number as additional information of the recorded video. Thereby, at the time of reproduction, it becomes possible to recognize the imaging location even with the recorded video from the same surveillance camera by this number. The recording location information may be added to the header portion of the video data from the surveillance camera.

  Further, when the control device 50 gives an instruction to the video recording device 41, it may be instructed to record the video of one of the monitoring cameras 11 and 13 as the video of the monitoring camera 12. In addition, when the video of either one of the monitoring cameras 11 and 13 is recorded as the video of the monitoring camera 12, the video of either one of the monitoring cameras 11 and 13 is recorded and monitored as the video of the monitoring camera 12. Since the same video as the video of either one of the cameras 11 and 13 is recorded, when the recording of the monitoring camera 12 is stopped and the video of the monitoring camera 12 is referred to later, Any one of the 13 images may be referred to.

  Furthermore, the system control unit 500 of the control device 50 instructs the video recording device 41 to transmit the video of one of the monitoring cameras 11 and 13 as the video of the monitoring camera 12 to the display device 71. Note that in this case as well, the video of either one of the monitoring cameras 11 and 13 and the video of the monitoring camera 12 are the same, so only one of the videos may be transmitted to the display device 71. Further, the control device 50 updates the video management information stored in the video management information storage unit 504 so that the setting changed due to the failure of the monitoring camera 12 is reflected in the video management information.

  With the above operation, the imaging location of the monitoring camera 12 where the failure has occurred is complemented and recorded by imaging by both the monitoring cameras 11 and 13. Further, in the display device 71, although the same image as the image of either one of the monitoring cameras 11 and 13 is displayed in the frame where the image captured by the monitoring camera 12 where the failure has occurred is originally displayed, the imaging by the monitoring camera 12 is performed. The location will be displayed.

  As described above, according to the first embodiment of the present invention, even when a failure occurs in one of the plurality of monitoring cameras, the imaging location of the monitoring camera in which the failure has occurred is monitored. By performing recovery by imaging with a camera, it is possible to prevent missing captured images at important imaging locations.

  In the above-described first embodiment of the present invention, after the video captured by the monitoring cameras 10 to 32 is transmitted to the video recording devices 41 to 43, the video recording devices 41 to 43 further display the video images. 73, the video captured by the surveillance cameras 10-32 is transmitted to the display devices 71-73, and then further transmitted from the display devices 71-73 to the video recording devices 41-43. It may be configured to be.
