Embodiment 1 FIG.
Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram showing a surveillance camera system according to Embodiment 1 of the present invention, and FIG. 2 is a multicast address assigned to the surveillance camera and each device used in the surveillance camera system and numbers assigned to each multicast address. It is a figure which shows correlation of these. In FIG. 1, the setting PC 105 and the upgrade PC 106 are shown, but these are for explanation of the embodiment described later, and are ignored in the first embodiment. .

  The surveillance camera system of the first embodiment includes an IP network 100 composed of an IP network cable and a plurality of HUBs, surveillance cameras 101-1 to 101-n connected to the IP network 100, and an IP network. Viewer devices 102-1 to 102-n that receive the images of surveillance cameras 101-1 to 101-n sent via 100 and display them on a monitor (not shown), and sent via IP network 100 Recording devices 103-1 to 103-n for recording the images of the coming surveillance cameras 101-1 to 101-n, surveillance cameras 101-1 to 101-n connected to the IP network 100, and viewer devices 102-1 to 102 -n and operation devices 104-1 to 104-n for operating and controlling the recording devices 103-1 to 103-n.

  The monitoring cameras 101-1 to 101-n described above are equipped with, for example, a turntable, a zoom lens, and a circuit unit (not shown) that converts analog video to be compatible with the network, and the viewer devices 102-1 to 102-102. -n is a multi-screen display function that divides the monitor screen into 4 screens, 9 screens, etc., a screen switching function, and a display position setting that sets which split screen the received video is displayed when the monitor is multi-screened It has functions. The recording devices 103-1 to 103-n have a function of displaying the recorded video on the monitor through the viewer devices 102-1 to 102-n.

  Each of the monitoring cameras 101-1 to 101-n, the viewer devices 102-1 to 102-n, the recording devices 103-1 to 103-n, and the operation devices 104-1 to 104-n has its own multicast address set. ing. Further, for example, the multicast addresses of the operation devices 104-1 to 104-n are set in the monitoring cameras 101-1 to 101-n, and the monitoring cameras 101-1 to 102-n are set in the monitoring devices 102-1 to 102-n. The multicast addresses 1 to 101-n and the multicast addresses of the operating devices 104-1 to 104-n are set, and the recording devices 103-1 to 103-n are assigned to the monitoring cameras 101-1 to 101-n. Each multicast address of n is set.

  As shown in FIG. 2, the multicast address set for each device or monitoring camera described above corresponds to a number assigned in advance, and is the same as the last number of the multicast address. By designating the number, the multicast address of the distribution source associated with the designated number is selected. Each number can be designated by an operation unit (not shown) provided in each device, for example. The selection of the operation devices 104-1 to 104-n for controlling the monitoring cameras 101-1 to 101-n is performed by selecting a transmission path (LAN, RS-232C, etc.) connected to the monitoring cameras 101-1 to 101-n. It can be done from the outside through.

In the surveillance camera system of the first embodiment configured as described above, an operation when a surveillance camera is arbitrarily selected from the viewer device and the recording device will be described.
When each of the monitoring cameras 101-1 to 101-n distributes video on the IP network 100 with its own multicast address, for example, operations provided in the viewer device 102-1 and the recording device 103-1, respectively When the number “1” assigned to the monitoring camera 101-1 is specified by the monitor, the viewer device 102-1 and the recording device 103-1 each set the multicast address “224.1.2.1” associated with the number “1”. Select from preset multicast addresses of surveillance cameras 101-1 to 101-n, and use this address “224.1.2.1” to receive the distribution video of surveillance camera 101-1 to HUB on IP network 100 Request. At this time, the HUB sends the video of the address “224.1.2.1” requested to be received to the viewer device 102-1 and the recording device 103-1 among the videos distributed from the monitoring cameras 101-1 to 101-n. Deliver each. On the other hand, the viewer apparatus 102-1 receives the video from the monitoring camera 101-1, displays it on the monitor, and the recording apparatus 103-1 records the received video from the monitoring camera 101-1. The distribution control by the HUB is performed by IGMP (Internet Group Management Protocol).

  As described above, since the video is received using the multicast addresses of the plurality of monitoring cameras 101-1 to 101-n that have distributed the video on the IP network 100, the connection of the monitoring cameras 101-1 to 101-n is performed. Video from multiple surveillance cameras 101-1 to 101-n connected to the IP network can be displayed on multiple monitors or recorded on recording devices 103-1 to 103-n without checking the status become.

Next, an operation when the viewer device receives an operation / control signal (hereinafter referred to as “operation / control command”) distributed from the operation device will be described.
For example, when an operation / control command for switching a monitor image, for example, is distributed from the operation device 104-1 to the IP network 100, the operation units provided in the viewer devices 102-1 to 102-n When the number “1” assigned to each operation device 104-1 is designated, each of the viewer devices 102-1 to 102-n is preset with the multicast address “224.1.5.1” associated with the number “1”. The operation device 104-1 to 104-n is selected from the multicast addresses, and the HUB on the IP network 100 is requested to receive the operation / control command of this address “224.1.5.1”. At this time, the HUB searches for the same address as the multicast address “224.1.5.1” requested to be received, and the operation / control command of the operating device 104-1 distributed by the multicast address “224.1.5.1”. Are distributed to each of the viewer apparatuses 102-1 to 102-n. At this time, each of the viewer devices 102-1 to 102-n switches the monitor image based on the received operation / control command.

  As described above, when each viewer device 102-1 to 102-n receives the operation / control command distributed from the operation device 104-1, the multicast address “224.1.5.1” of the operation device 104-1 is used. Therefore, there is no need to specify the viewer devices 102-1 to 102-n to be operated / controlled from the operation device 104-1 side, and the viewer devices 102-1 to 102-1 connected to the IP network 100 are not required to be specified. It is possible to switch the monitor image to 102-n at the same time, and to simultaneously switch among a plurality of viewer devices. In addition, the images of the monitoring cameras 101-1 to 101-n can be arbitrarily displayed on the monitor without confirming the connection state of the monitoring cameras 101-1 to 101-n.

Next, an operation when the monitoring camera receives an operation / control command distributed from the operation device will be described.
For example, when an operation / control command for operating the monitoring camera is distributed from the operation device 104-1 to the IP network 100, for example, the monitoring cameras 101-1 to 101-n are selected by an external operation, and When the number “1” assigned to the operation device 104-1 is designated for the monitoring cameras 101-1 to 101-n, each of the monitoring cameras 101-1 to 101-n is associated with the number “1”. Multicast address “224.1.5.1” is selected from the preset multicast addresses of operating devices 104-1 to 104-n, and the operation / control command of this address “224.1.5.1” is received on IP network 100. Request to HUB. On the other hand, the HUB searches for the same address as the multicast address “224.1.5.1” for which the reception request has been made, and sends the operation / control command of the operating device 104-1 distributed by the multicast address “224.1.5.1”. Delivered to each of the monitoring cameras 101-1 to 101-n. At this time, each of the monitoring cameras 101-1 to 101-n operates based on the received operation / control command.

  As described above, when each of the monitoring cameras 101-1 to 101-n receives the operation / control command distributed from the operation device 104-1, the multicast address “224.1.5.1” of the operation device 104-1 is used. Therefore, there is no need to specify the monitoring cameras 101-1 to 101-n to be operated and controlled from the operation device 104-1 side, and the monitoring cameras 101-1 to 101-1 connected to the IP network 100 are not required. 101-n can be operated simultaneously, and arbitrary control can be performed without confirming the connection state of the monitoring cameras 101-1 to 101-n.

Next, an example of an operation / control command of the operation device and a viewer device that automatically operates according to this command example will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of an operation / control command for the viewer device by distribution of the operation device.
“Destination 1” shown in FIGS. 3A and 3B is a model to be received, and “Destination 2” is a number assigned to the viewer device of the target model. These model names and identification numbers are set in advance as identification information in the viewer devices 102-1 to 102-n and the operation devices 104-1 to 104-n connected on the IP network 100. Through this, it is determined whether or not the viewer devices 102-1 to 102-n on the receiving side are commands to themselves. Further, “command operation instruction content” shown in FIGS. 3A and 3B is an operation / control command that gives an operation instruction to each of the viewer apparatuses 102-1 to 102-n. In the “4-screen A pattern display” and “4-screen B pattern display” commands, “4-screen” is a display pattern command to be divided into the upper two screens and the lower two screens on the monitor screen. “A” described here is a command for displaying, for example, images of the monitoring cameras 101-1 to 101-4, and “B” is a command for displaying images of the monitoring cameras 101-5 to 101-8, for example. The numbers of the monitoring cameras for “A” and “B” in the four screens are set in advance in the viewer apparatuses 102-1 to 102-n.

  Each viewer device 102-1 to 102-n periodically receives operation / control commands using the multicast addresses “224.1.5.1” to “224.1.5.n” of the operation devices 104-1 to 104-n. Demands. In this state, for example, when the operation / control command shown in FIG. 3A is distributed from the operation device 104-1 at the multicast address “224.1.5.1”, each of the viewer devices 102-1 to 102-n passes through the HUB. The operation / control command is received. At this time, each of the viewer apparatuses 102-1 to 102-n extracts its own operation / control command through the destinations 1 and 2 attached to the operation / control command, and operates based on the command.

  In this case, since the command of the viewer apparatus 102-1 is “4-screen A pattern display”, the monitor screen is divided into four as described above, and the monitoring cameras 101-1 to 101-2 are based on the command “A”. The multicast addresses “224.1.2.1” to “224.1.2.4” of 101-4 are selected from the multicast addresses of the pre-registered surveillance cameras 101-1 to 101-n, and the surveillance cameras 101-1 to 101 of these addresses are selected. -4 is requested to the HUB on the IP network 100 to receive the distribution video. Further, since the other viewer apparatuses 102-2 to 102-n are “no command”, the current state is maintained according to the command.

  On the other hand, when the HUB detects the reception request of the distribution video of the monitoring cameras 101-1 to 101-4, the address “224.1” of the video distributed from the monitoring cameras 101-1 to 101-n is requested. Each video of “.2.1” to “224.1.2.4” is distributed to the viewer apparatus 102-2. At this time, the viewer apparatus 102-1 receives the images from the monitoring cameras 101-1 to 101-4 and displays them on the four screens of the monitor based on the preset display positions.

  When the viewer apparatus 102-1 displays each image from the monitoring cameras 101-1 to 101-4 on the four screens of the monitor, the operation / control command shown in FIG. Is distributed at the multicast address “224.1.5.1”, each viewer apparatus 102-1 to 102-n receives the operation / control command through the HUB in the same manner as described above. At this time, each of the viewer apparatuses 102-1 to 102-n extracts its own operation / control command through the destinations 1 and 2 attached to the operation / control command, and operates based on the command.

  In this case, since the command is “4-screen B pattern display”, the viewer apparatus 102-1 holds four screens of the monitor, and the monitoring cameras 101-5 to 101-8 are based on the command “B”. Multicast addresses “224.1.2.5” to “224.1.2.8” are selected from the multicast addresses of the pre-registered surveillance cameras 101-1 to 101-n, and the distribution of surveillance cameras 101-5 to 101-8 of these addresses is performed Request the HUB to receive video. Further, since the command is “4-screen A pattern display”, the viewer apparatus 102-2 divides the monitor screen into four, and multicasts the monitoring cameras 101-1 to 101-4 based on the command “A”. The addresses “224.1.2.1” to “224.1.2.4” are selected from the multicast addresses of the pre-registered surveillance cameras 101-1 to 101-n, and the distribution video of the surveillance cameras 101-1 to 101-4 at these addresses Is requested from the HUB. Further, since the other viewer apparatuses 102-3 to 102-n are “no command”, the current state is maintained according to the command.

  On the other hand, when the HUB detects the distribution video reception request of the monitoring cameras 101-1 to 101-4 and 101-5 to 101-8, among the images distributed from the monitoring cameras 101-1 to 101-n, Each video at addresses “224.1.2.1” to “224.1.2.4” requested to be received is distributed to the viewer apparatus 102-2, and each video at addresses “224.1.2.5” to “224.1.2.8” is distributed to the viewer apparatus 102. Deliver to -1. At this time, the viewer apparatus 102-1 switches and displays each image of the monitoring cameras 101-1 to 101-4 displayed on the four screens of the monitor to each image of the monitoring cameras 101-5 to 101-8. The device 102-2 displays each video from the monitoring cameras 101-1 to 101-4 on four screens of the monitor.

  When the operation device 104-1 repeatedly distributes the operation / control commands shown in FIGS. 3A and 3B, for example, every 5 seconds, the viewer device 102-1 receives from the monitoring cameras 101-1 to 101-4. The images of the monitoring cameras 101-5 to 101-8 are switched and displayed every 5 seconds, and the viewer apparatus 102-2 displays 10 images from the monitoring cameras 101-1 to 101-4. Display every second.

  From the above, without specifying the viewer devices 102-1 to 102-n to be operated and controlled from the operation device 104-1 side, the viewer devices 102-1 to 102-n connected to the IP network 100 are designated. On the other hand, it is possible to control all at once, that is, it is possible to perform a sequence operation, and it is also possible to switch images at different timings among a plurality of viewer devices.

Here, an operation of manually displaying a plurality of videos on a monitor will be described.
For example, the monitor screen is divided into four screens using the operation unit of the viewer device 102-2, and the numbers “2” to “5” assigned to the monitoring cameras 101-2 to 101-5 are designated on each screen. Then, the viewer apparatus 102-2 recognizes the display positions of the images of the monitoring cameras 101-2 to 101-5, and the multicast addresses “224.1.2.2” to “5” associated with the numbers “2” to “5”, respectively. Select "224.1.2.5" from the preset multicast addresses of surveillance cameras 101-1 to 101-n, and use these addresses to receive the distribution video of surveillance cameras 101-2 to 101-5 on the IP network. Request to HUB above 100. Upon receiving this request, the HUB transmits each video of the addresses “224.1.2.2” to “224.1.2.5” requested to be received among the videos distributed from the monitoring cameras 101-1 to 101-n to the viewer device 102. Delivered to -2. At this time, the viewer apparatus 102-2 receives the images from the monitoring cameras 101-2 to 101-5 and displays them on the four screens of the monitor based on the display positions designated by the operation unit.

  As a result, a multi-screen display can be performed by arbitrarily selecting a monitoring camera without confirming the connection state of the monitoring cameras 101-1 to 101-n.

Next, an example of the operation / control command of the operation device for the surveillance camera and the surveillance camera that operates automatically with this command example will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of an operation / control command for the monitoring camera by distribution of the operation device.
“Destination 1” shown in FIGS. 4A and 4B is a model to be received as in FIG. 3, and “Destination 2” is a number assigned to the monitoring camera of the target model. These model names and identification numbers are set in advance as identification information in the monitoring cameras 101-1 to 101-n and the operation devices 104-1 to 104-n connected on the IP network 100. The monitoring cameras 101-1 to 101-n on the receiving side determine whether or not they are commands to themselves. Further, “command operation instruction content” shown in FIGS. 4A and 4B is an operation / control command that gives an operation instruction to each of the monitoring cameras 101-1 to 101-n.

  Each of the monitoring cameras 101-1 to 101-n periodically receives operation / control commands using the multicast addresses “224.1.5.1” to “224.1.5.n” of the operation devices 104-1 to 104-n. Demands. In this state, for example, when the operation / control command shown in FIG. 4A is distributed from the operation device 104-1 at the multicast address “224.1.5.1”, each of the monitoring cameras 101-1 to 101-n transmits through the HUB. The operation / control command is received. At this time, each of the monitoring cameras 101-1 to 101-n extracts its own operation / control command through the destinations 1 and 2 attached to the operation / control command, and operates based on the command.

  In this case, since the command of the monitoring camera 101-1 is “move to preset position 1”, the lens is controlled to move to position 1 based on the command. Since “turn left to turntable”, the turntable is turned to the left based on the command. Further, since the other monitoring cameras 101-3 to 101-n are “no command”, the current state is maintained according to the command. In this state, when the operation / control command shown in FIG. 3B is again delivered from the operation device 104-1 at the multicast address “224.1.5.1”, each of the monitoring cameras 101-1 to 101-n Similarly, the operation / control command is received through the HUB. At this time, each of the monitoring cameras 101-1 to 101-n extracts its own operation / control command through the destinations 1 and 2 attached to the operation / control command, and operates again based on the command. In this case, since the command of the monitoring camera 101-1 is “move to preset position 2”, the lens is controlled so as to move from position 1 to position 2. `` Swivel right '', so the turntable is turned from left to right based on the command, and surveillance camera 101-n is `` Start automatic turn '', so the turntable is automatically turned on based on that command. The other surveillance cameras 101-3... Are "no command" and maintain the current state according to the command.

  For example, when the operation device 104-1 repeatedly distributes the operation / control commands shown in FIGS. 4A and 4B every 10 seconds, the monitoring camera 101-1 changes the preset position every 10 seconds, The monitoring camera 101-2 changes the turning direction of the turntable every 10 seconds, and the monitoring camera 101-n first turns automatically after 10 seconds, and then turns automatically every 20 seconds.

  From the above, without specifying the monitoring cameras 101-1 to 101-n to be operated and controlled from the operation device 104-1 side, the monitoring cameras 101-1 to 101-n connected to the IP network 100 are not designated. It is possible to control all at once, that is, it is possible to perform a sequence operation, and furthermore, it is possible to perform different operations at the same timing between multiple surveillance cameras, and between multiple surveillance cameras. Interlocking operation with is also possible.

Embodiment 2. FIG.
In the second embodiment, a setting personal computer (PC) 105 having data setting means is connected to an IP network 100 (see FIG. 1). The setting PC 105 is used to distribute various setting data for change to, for example, the monitoring cameras 101-1 to 101-n, the viewer devices 102-1 to 102-n, and the recording devices 103-1 to 103-n. This is done by using a preset multicast address. As shown in FIG. 5, the setting data includes “destination 1” and “destination 2” as identification information and a “setting change presence / absence” command. B, C) are written. Further, the setting PC 105 is configured to create a setting completion device list shown in FIG. 6 on the basis of a setting completion notification transmitted from each of the above devices by UDP / IP or TCP / IP.

  The aforementioned monitoring cameras 101-1 to 101-n, viewer devices 102-1 to 102-n and recording devices 103-1 to 103-n are set with the multicast address of the setting PC 105, and the setting data is transmitted through the HUB. When the distribution is detected, a setting data reception request is issued to the HUB using the multicast address. When each device changes existing data based on the change data, the device transmits a setting completion notification to the destination setting PC 105 using the UDP / IP or TCP / IP.

Next, when the setting PC 105 for explaining the operation of the second embodiment distributes the setting data shown in FIG. 5 on the IP network 100 with its own multicast address, the HUB is connected to the monitoring cameras 101-1 to 101-n, This is notified to the viewer devices 102-1 to 102-n and the recording devices 103-1 to 103-n.

The upgrade PC 106 is for distributing upgrade data to, for example, the monitoring cameras 101-1 to 101-n, the viewer devices 102-1 to 102-n, and the recording devices 103-1 to 103-n. This is performed using a preset multicast address. As shown in FIG. 7, the upgrade data includes “destination 1” and “destination 2” as identification information, and a command “presence / absence of upgrade data”. In addition, the upgrade PC 106 creates a list of upgrade completion apparatuses shown in FIG. 8 based on the upgrade completion notification transmitted from each of the apparatuses by UDP / IP or TCP / IP. Yes.

  The above-described surveillance cameras 101-1 to 101-n, viewer devices 102-1 to 102-n, and recording devices 103-1 to 103-n are set with the multicast address of the upgrade PC 106, and the upgrade data is transmitted through the HUB. When it is detected that is received, upgrade request reception request is sent to the HUB using the multicast address. In addition, when each device performs version upgrade based on the version upgrade data, the device transmits a version upgrade completion notification to the destination version upgrade PC 106 using the UDP / IP or TCP / IP.

Next, the operation of the third embodiment will be described.
When the upgrade PC 106 distributes the upgrade data shown in FIG. 7 on the IP network 100 with its own multicast address, the HUB is connected to the monitoring cameras 101-1 to 101-n, the viewer devices 102-1 to 102-n, and the recording. This is notified to the devices 103-1 to 103-n. At this time, the monitoring cameras 101-1 to 101-n, the viewer apparatuses 102-1 to 102-n, and the recording apparatuses 103-1 to 103-n use the multicast address of the upgrade PC 106 to receive the upgrade data. When the upgrade data is received from the upgrade PC 106 by this request, the upgrade data for itself is extracted through the destinations 1 and 2. In this case, the surveillance cameras 101-1 to 101-n are upgraded based on the upgrade data, and the viewer devices 102-1 to 102-n and the recording devices 103-1 to 103-n have no upgrade data. Maintain the current state. Thereafter, the monitoring cameras 101-1 to 101-n transmit a version upgrade completion notification to the destination version upgrade PC 106 using UDP / IP or TCP / IP, respectively. On the other hand, upon receiving the upgrade completion notification, the upgrade PC 106 creates a list of upgrade completion apparatuses shown in FIG.

  As described above, according to the third embodiment, the monitoring cameras 101-1 to 101-n, the viewer devices 102-1 to 102-n and the recording devices 103-1 to 103-n connected to the IP network 100 are connected. On the other hand, the version can be upgraded all at once, and there is an effect that the maintenance work of each apparatus can be performed efficiently.
