An image recording device 5 for recording information is an alarm device for sounding an alarm sound or displaying an alarm.
[0004]
A plurality of contact outputs from the security system 1 are respectively input to the contact input terminals 2, and individual wirings of the contact input terminals 2 are connected to the monitoring camera 3 and the image recording device 4 via cables such as “CB01” in FIG. And an alarm device 5 respectively.
[0005]
Here, the operation of the conventional example shown in FIG. 5 will be described. The security system 1 outputs an abnormality such as a fire detected by various sensors or the like (not shown) or intrusion of a suspicious person to the contact input terminal 2 as a contact output.
[0006]
Individual contact information input to the contact input terminal 2 is transmitted via a cable indicated by “CB01” in FIG. 5 and supplied to the monitoring camera 3, the image recording device 4, and the alarm device 5, respectively.
[0007]
The device such as the monitoring camera 3 that has received such contact information performs an operation or the like set in advance on the contact information.
[0008]
For example, if the input terminal indicated by “CT01” in FIG. 5 is connected to the monitoring camera 3 and there is a contact input to the input terminal indicated by “CT01” in FIG. 5, the monitoring camera 3 will pan, tilt, or An operation such as zooming is performed to capture a specific angle of view and capture an image.
[0009]
Further, for example, when the input terminal indicated by “CT02” in FIG. 5 is connected to the image recording device 4 and there is a contact input to the input terminal indicated by “CT02” in FIG. 3 and the like are recorded.
[0010]
Further, for example, the input terminal indicated by “CT03” in FIG. 5 is connected to the alarm device 5, and when there is a contact input to the input terminal indicated by “CT03” in FIG. 5, the alarm device 5 sounds an alarm or the like. , Alarm display.
[0011]
When the contact input terminal 2 is physically separated from the surveillance camera 3 and other devices, there is a method using a means for transmitting contact information.
[0012]
FIG. 6 is a configuration block diagram showing an example of such a conventional surveillance camera system. 6, 1, 2, 3, 4 and 5 are denoted by the same reference numerals as in FIG. 5, and 6 and 7 are contact information transmitting means.
[0013]
A plurality of contact outputs from the security system 1 are respectively input to the contact input terminals 2, and individual wires of the contact input terminals 2 are connected to contact information transmitting means 6 installed near the contact input terminals 2.
[0014]
The output of the contact information transmitting means 6 is connected to the contact information transmitting means 7 installed near the monitoring camera 3 or the like via a network such as the Internet, a dedicated line, a telephone line or the like indicated by "CM11" in FIG.
[0015]
For example, as a method of transmitting contact information to a remote place, a specific communication protocol of the contact information transmitting means 6 and 7 is used, or a BACnet having a contact information transmitting procedure (standard of building equipment system communication: ANIS / ASHHRE standard) 135-1995) or LonTalk.
[0016]
The output of the contact information transmitting means 7 is connected to the monitoring camera 3, the image recording device 4, and the alarm device 5, respectively.
[0017]
Here, the operation of the conventional example shown in FIG. 6 will be described. The security system 1 outputs an abnormality such as a fire detected by various sensors or the like (not shown) or intrusion of a suspicious person to the contact input terminal 2 as a contact output.
[0018]
The individual contact information input to the contact input terminal 2 is input to the contact information transmitting means 6, and the contact information transmitting means 6 communicates with the contact information transmitting means 7 connected via a network indicated by "CM11" in FIG. Data communication is performed between them based on a predetermined communication protocol.
[0019]
The contact information transmitting means 7 returns the received data to contact information and supplies it to the monitoring camera 3, the image recording device 4, and the alarm device 5, respectively.
[0020]
The device such as the monitoring camera 3 that has received such contact information performs an operation or the like set in advance on the contact information.
[0021]
For example, the contact information transmitting means 7 supplies contact information to the surveillance camera 3 when receiving data indicating that there is a contact input to the input terminal indicated by "CT11" in FIG. An operation such as pan, tilt, or zoom is performed based on the contact information to capture a specific angle of view and capture an image.
[0022]
Further, for example, when the contact information transmitting means 7 receives data indicating that there is a contact input to the input terminal indicated by “CT12” in FIG. 6, the contact information transmitting means 7 supplies the contact information to the image recording device 4 and Records an image captured by the monitoring camera 3 or the like based on the supplied contact information.
[0023]
Further, for example, when the contact information transmitting means 7 receives data indicating that there is a contact input to the input terminal indicated by "CT13" in FIG. 6, the contact information transmitting means 7 supplies the contact information to the alarm device 5, and the alarm device 5 supplies the contact information. An alarm is sounded or an alarm is displayed based on the provided contact information.
[0024]
[Problems to be solved by the invention]
However, in the conventional example shown in FIG. 5, since the individual wiring of the contact input terminal 2 is extended and wired to a device such as the surveillance camera 3, if the number of the contact input terminals becomes large, the wiring cost and cost are reduced. There was a problem that the construction was complicated.
[0025]
In the conventional example shown in FIG. 6, the wiring cost and the like are improved as compared with the conventional example shown in FIG. There was the problem I said.
[0026]
For example, the contact information transmitting means 7 only supplies contact information to the monitoring camera 3 when receiving data indicating that there is a contact input to the input terminal indicated by “CT11” in FIG. It is not provided to other devices (for example, the alarm device 5 or the like).
[0027]
In addition, when a communication protocol having a contact information transmission procedure such as BACnet or LonTalk is used, the surveillance camera cannot be directly controlled by the communication protocol. In addition, there is a problem that it is necessary to set the contact information transmission means 7 for each application system in order to realize a composite function such as image recording control and alarm output control.
Therefore, an object of the present invention is to realize a surveillance camera system that can easily cooperate with a security system using a communication protocol having a contact information transmission procedure, and a building surveillance system using the same.

[0044]
A plurality of contact outputs are respectively input to the contact input terminals 8, and individual wirings of the contact input terminals 8 are connected to a contact information transmission device 9 installed near the contact input terminals 8.
[0045]
The output of the contact information transmission device 9 is connected via a network 100 to a camera control device 10 installed near a monitoring camera or the like.
[0046]
Then, the output of the camera control device 10 is connected to the monitoring cameras 11, 12, and 13, the image recording device 14, and the alarm device 15, respectively.
[0047]
FIG. 2 is a configuration block diagram showing a specific example of the camera control device 10. In FIG. 2, reference numerals 10 and 100 denote the same reference numerals as in FIG. 1, reference numeral 16 denotes communication means for performing communication using a general-purpose communication protocol such as UDP / IP (User Datagram Protocol / Internet Protocol), and reference numeral 17 denotes a contact point such as BACnet. Contact information extracting means for extracting contact information using a communication protocol having an information transmission procedure; 18, virtual contact means; 19, processing determining means; 20, storage means for storing information such as definition information; Control means, 22 is an alarm control means, and 23 is an image recording control means.
[0048]
Data from the network 100 is input to the communication unit 16, and the output of the communication unit 16 is connected to the contact information extraction unit 17. The output of the contact information extracting means 17 is connected to the virtual contact means 18, and the output of the virtual contact means 18 is connected to the processing determining means 19.
[0049]
The output of the storage means 20 is also connected to the processing determination means 19, and the output of the processing determination means 19 is connected to the camera control means 21, the alarm control means 22, and the image recording control means 23, respectively.
[0050]
Here, the operation of the embodiment shown in FIG. 1 will be described with reference to FIG. The contact signal input to the contact input terminal 8 is supplied to the contact information transmission device 9, and the contact information transmission device 9 transmits the contact information to the camera control device 10 via the network 100 using a general-purpose communication protocol such as BACnet. .
[0051]
For example, when there is a contact input to the input terminal indicated by “CT21” in FIG. 1, the contact information transmission device 9 generates transmission data based on a general-purpose communication protocol such as BACnet, and outputs UDP / IP data. And the like, and transmits it on the network 100.
[0052]
The camera control device 10 controls the surveillance cameras 11, 12 and 13 based on the definition information set in advance with respect to the contact information received via the network 100, controls the recording of the image information to the image recording device 14, and the alarm device. The control of the alarm process in 15 is performed.
[0053]
For example, the communication unit 16 receives data transmitted from the network 100 by UDP / IP or the like, extracts transmission data generated based on a general-purpose communication protocol such as BACnet, and outputs the data to the contact information extraction unit 17.
[0054]
Then, the contact information extracting means 17 extracts contact information such as that there is a contact input to the input terminal indicated by “CT21” in FIG. 1 from the transmission data based on a general-purpose communication protocol such as BACnet and outputs it to the virtual contact means 18. I do.
[0055]
Here, the virtual contact means 18 is means for providing a virtual contact (virtual contact) for each contact input on the storage means or the like, and for holding and managing the state (ON / OFF) of each contact input. The state of the corresponding virtual contact is changed based on the contact information (state of each contact input) input from the information extracting means 17 and the contents of the change of the virtual contact are output to the processing determination means 19 at the subsequent stage.
[0056]
For example, the virtual contact unit 18 changes the state of the virtual contact corresponding to the contact input indicated by “CT21” in FIG. , Transition from OFF to ON.)
[0057]
The processing determining means 19 determines the processing content by comparing the change content from the virtual contact means 18 with the definition information stored in the storage means 20, and determines the processing content, and the camera control means 21, the alarm control means 22, and the image recording control means 23 , And outputs the processing contents.
[0058]
The camera control unit 21, the alarm control unit 22, and the image recording control unit 23 which have received the processing contents control the monitoring cameras 11 to 13, the alarm device 15, and the image recording device 14 according to the processing contents.
[0059]
For example, when the state of the virtual contact corresponding to the contact input “CT21” in FIG. 1 changes from OFF to ON in the definition information stored in the storage unit 20, the monitoring camera 11 is controlled to perform pan, tilt, or If it is described that control such as zooming is performed and a specific angle of view is captured to capture an image, the processing determination unit 19 outputs such processing contents to the camera control unit 21.
[0060]
Further, for example, when the state of the virtual contact corresponding to the contact input of “CT21” in FIG. 1 changes from OFF to ON in the definition information stored in the storage unit 20, the alarm device 15 displays an alarm. If so, the processing determining means 19 outputs such processing contents to the alarm control means 22.
[0061]
In addition, by appropriately rewriting such definition information, it becomes possible to flexibly utilize the contact information, which is a problem in the conventional example.
[0062]
For example, even when contact information indicating that a contact input of “CT22” in FIG. 1 has been received is received, any of the monitoring cameras 11 to 13, the image recording device 14, and the alarm device 15 can rewrite the definition information. Even if there is, it can be a control target.
[0063]
Further, even when a communication protocol such as BACnet that cannot directly control the surveillance camera is used, multiple functions such as surveillance camera control, image recording control, and alarm output control are realized for the contact information. Even so, it is possible to easily construct a surveillance camera system by appropriately rewriting the definition information.
[0064]
As a result, the virtual contact means 18 is provided with a virtual contact for each contact input, the state of the virtual contact is changed based on the contact information, and the state of the contact input is maintained and managed. By determining the processing content in comparison with the definition information, cooperation with a security system using a communication protocol having a contact information transmission procedure is facilitated.
[0065]
FIG. 3 is a block diagram showing an embodiment of a building monitoring system using the monitoring camera system according to the present invention. In FIG. 3, 24 and 25 are monitoring terminals, 26, 27, 28, 29 and 30 are Web cameras, 31 and 32 are camera control devices, and 33, 34 and 35 are contact information transmission devices.
[0066]
The monitoring terminals 24 and 25, the Web cameras 26, 27, 28, 29 and 30, and the camera control devices 31 and 32 are connected to a network such as TCP / IP as shown by "TN31", "TN32" and "TN33" in FIG. Connected respectively.
[0067]
The camera control devices 31 and 32 and the contact information transmission devices 33, 34 and 35 are respectively connected to a network such as a BACnet / IP as shown by "BN31" in FIG.
[0068]
Here, the operation of the embodiment shown in FIG. 3 will be described with reference to FIG. FIG. 4 is an explanatory diagram showing a specific example of the definition information. However, description of the same contents as those of the embodiment shown in FIG. 1 will be omitted.
[0069]
The monitoring terminals 24 and 25 appropriately display images captured by the Web cameras 26 to 30 obtained via the network, and the operator monitors the displayed images.
[0070]
In FIG. 3, “SN31”, “SN32”, “SN33”, “SN34”, “SN35”, and “SN36” are intrusion sensors and fire sensors installed in various places of the building to be monitored. When a contact signal is output from an intrusion detection or the like. As described above, the states of the virtual contacts of the camera control devices 31 and 32 change.
[0071]
Then, the camera control devices 31 and 32 determine the processing content by comparing the change content of the virtual contact point and the definition information, and perform control such as pan, tilt, or zoom of the Web cameras 26 to 30.
[0072]
In addition, the camera control devices 31 and 32 transmit a message indicating occurrence of an abnormality to the monitoring terminals 24 and 25 as necessary based on a change in the state of the virtual contact, using a communication message on a TCP / IP (Transmission Control Protocol / Internet Protocol) or a general-purpose message. And send it by e-mail.
[0073]
For example, when there is a description as shown in FIG. 4 as the definition information, as shown by “ID41” in FIG. 4, in the initial state, the IP addresses are “xx.xx.xx.133” and “xx.xx.xx. Since the direction of the Web camera, which is 77 ", is described to move in the direction" 1 ", the camera control devices 31 and 32 control the predetermined Web camera to move in the direction" 1 ".
[0074]
Here, the angle of view corresponding to the direction “1” is registered as a preset point on the Web camera. Similarly, the direction “x” indicates a specific angle of view registered on the Web camera.
[0075]
On the other hand, when the state of the “contact 1” changes from “OFF” to “ON” as shown by “CD41” in FIG. 4, the IP addresses become “xx.xx.xx.133” and “xx.xx.xx. Since the direction of the Web camera which is 77 "is described to move in the direction" 2 "and the direction" 4 ", the camera controllers 31 and 32 determine that the predetermined Web camera has the direction" 2 "and the direction" 4 ". Control to move to 4 ".
[0076]
When the state of the “contact 2” changes from “OFF” to “ON” as shown by “CD42” in FIG. 4, the direction of the Web camera whose IP address is “xx.xx.xx.77” is changed to the direction. Since the description is made so as to move to “5”, the camera control devices 31 and 32 control the direction of the predetermined Web camera to move in the direction “5”.
[0077]
Further, when the state of the “contact 1” and “contact 2” transitions from “ON” to “OFF”, the initial state, that is, the IP address is “xx.xx.xx.133” and “xx.xx.xx.77”. Since it is described that the direction of the Web camera “” moves in the direction “1”, the camera control devices 31 and 32 perform control such that the direction of the predetermined Web camera moves in the direction “1”.
[0078]
As a result, a virtual contact is provided for each contact input in the camera control devices 31 and 32, the state of the virtual contact is changed based on the contact information to maintain and manage the state of the contact input, and the contents of the change and the definition information of the virtual contact are changed. By deciding the processing content by comparing with the above, cooperation with a security system using a communication protocol having a contact information transmission procedure is facilitated.
[0079]
In the embodiment shown in FIG. 1, the contact information is collected by the contact information transmitting device 9 and transmitted over the network 100. However, a security sensor, a card reader, or the like that performs communication using a communication protocol such as BACnet or LonTalk. May be directly connected to the network to communicate with the camera control device.
[0080]
In this case, since the contact information transmitting means 9 becomes unnecessary, the cost of the surveillance camera system and the like can be reduced, and the degree of freedom of the configuration of the surveillance camera system is improved.
[0081]
Also, in the embodiment shown in FIG. 1 and the like, a virtual contact is simply provided for each contact input and the virtual contact is operated based on the contact information (the state of each contact input). A virtual contact may be provided for each type of information, such as information relating to the change of the value of the sensor, or the like, and the virtual contact may be operated based on the contact information (the state of the various information).
[0082]
In other words, it is also possible to provide a virtual contact for each contact information indicating the state of each contact input or various information, operate the virtual contact based on the content of the contact information, and hold and manage the contact information with the virtual contact. is there.
[0083]
In the embodiment shown in FIG. 1, the image recording device and the alarm device are illustrated together with the monitoring camera. However, the essential components are the monitoring camera, and the image recording device and the alarm device can be combined as needed. good.
[0084]
Similarly, in the embodiment shown in FIG. 2, the alarm control means and the image recording control means are illustrated together with the camera control means. However, the essential components are the camera control means, and the alarm control means and the image recording control means. May be appropriately combined as needed.
[0085]
In the embodiment shown in FIG. 2, the communication means 16 and the contact information extracting means 17 are described separately, but if the contact information extracting means 17 is provided with a communication function using a general-purpose communication protocol such as UDP / IP. The communication means 16 is unnecessary.
[0086]
The virtual contact means 18 is a means for providing a virtual contact (virtual contact) on a storage means or the like for each contact input and holding and managing the state (ON / OFF) of the contact input. According to the necessity of the above, a calculation process such as sum or product may be performed between a plurality of virtual contacts, and the calculation result may be held and managed as a new virtual contact.
[0087]
In this case, since various combinations of virtual contacts can be expressed as new virtual contacts, it is effective in determining the processing content of complicated conditions, and since the conditions can be set at virtual contacts, complex definition information can be set. Becomes easier.
[0088]
For example, it is effective when determining the processing content of complicated conditions such as corresponding to a change in the state of the contact point of the door of the entrance only during the period when the alert contact is “ON”.
[0089]
Further, in the embodiment shown in FIG. 1, the camera control device 10 and each of the monitoring cameras 11 to 13 are described separately, but each of the monitoring cameras 11 to 13 may have the function of the camera control device. .
