Description

  The present invention relates to a remote monitoring system capable of confirming an image of a monitoring area captured by a network camera via an external network such as the Internet.

Conventionally, various remote monitoring systems that can check an image of a monitoring area captured by a network camera via an external network such as the Internet have been provided (for example, see Patent Document 1). Here, since it is not preferable for security to directly access the network camera from the external network, a proxy server (proxy server device) is usually installed, and the proxy server device replaces the network camera. The image data is transferred to the center device via the external network. The center device stores image data transferred from the proxy server device, and transmits desired image data to the personal computer or mobile phone via an external network in response to a monitoring request from a terminal device such as a personal computer or mobile phone. . Here, a name (for example, the name of the room in the monitoring area such as “living room” or “kitchen”) is assigned to each network camera so that the image data can be easily monitored. The assigned name is acquired, and the image data of each network camera is managed by the name. Then, the center device creates screen information that displays a list of network camera names based on the network camera information received from the proxy server device, transmits the screen information to the terminal device, and the screen information is stored in the display device included in the terminal device. It is displayed on the screen so that the user can easily select the network camera to be monitored.

In this homepage, the names of the equipment devices X1 and X2 included in the subsystem SS1 and characters indicating the installation location (for example, “living air conditioner”, “living lighting”, etc.), and the operating state of each equipment device X1 and X2 , A button corresponding to an operation for inverting the operation state of each equipment device X1, X2, a button for returning to the portal site of the integrated management device TM, and the like are displayed. Therefore, it is possible to monitor (confirm) the operating state of each equipment device X1, X2 from the information displayed on the homepage (8).

  Here, in the case of performing control for reversing the operating state of any of the equipment devices Xm, for example, control for turning off the currently lit lighting fixture (facility device X2), the operating state of the equipment device X2 is reversed on the homepage. The touch panel is operated on the button corresponding to the operation (9). Then, a message indicating that the button has been operated by the web browser, that is, a message (request message) requesting to turn off the lighting device (facility device X2) is sent to the IP address of the facility device controller C1 through the home network. It is transmitted (10). Then, in the equipment controller controller 10 of the equipment controller C1 that has received this request message, the lighting equipment (facility equipment X2) is turned off by turning off the relay of the relay terminal section 15 via the lighting equipment interface section 14. (11). Then, if the equipment controller controller 10 updates the contents of the homepage in response to the lighting equipment (equipment X2) being turned off, and transmits the updated homepage data to the display control device CV (12), the display control is performed. By opening the data (file) with a web browser executed by the microcomputer unit 50 of the apparatus CV, the updated home page of the subsystem SS1 is displayed on the liquid crystal display of the display unit 52 (13). In the homepage, the operating state of the lighting fixture (equipment device X2) is changed from lighting to extinguishing.

  Next, the operation in the case of controlling and monitoring the equipment device Xm from outside the house using a portable terminal device (for example, the mobile phone MP) will be described with reference to the sequence diagram of FIG. Here, if the web server function of each controller Cn always opens a port to the external network (Internet), for example, there is a high possibility that a malicious intruder will cause an abnormality in the system. In the embodiment, the web server function of each controller Cn normally polls the center device SV while closing the port, and the request message received from the portable terminal device is held in the center device SV. Then, the home network is protected by transferring the request message from the center device SV at the time of polling by the controller Cn that is the destination of the request message.

  As described above, each controller Cn periodically polls the center device SV, and if the center device SV does not hold a request message from the mobile phone MP, the center device SV simply receives an acknowledgment (ACK). ) Is simply returned to the controller Cn. Here, the householder uses the mobile phone MP to send a request message (for example, a monitoring request message for the operating state of the lighting fixture) to the center device SV (1), and after the monitoring request message is held by the center device SV. When polled from the equipment controller C1 (2), the center apparatus SV transmits (transfers) the monitoring request message received and held from the mobile phone MP to the equipment controller C1 (3). In the equipment controller C1 that has received this monitoring request message, the equipment controller controller 10 creates a monitoring response message indicating the current operating state (for example, lighting) of the lighting fixture (facility equipment X2) and sends it to the center apparatus SV. Reply (4). The monitoring response message is transferred from the center device SV to the cellular phone MP (5), and the monitoring response message transferred from the sensor device SV is displayed on the liquid crystal screen of the cellular phone MP, so that the operating state (lighting) of the lighting fixture is displayed. Can be confirmed.

  Further, the householder transmits a request message (for example, a control request message for turning off the lighting fixture) to the center apparatus SV using the mobile phone MP (6), and the equipment is stored after the control request message is held in the center apparatus SV. When polled from the controller C1 (7), the center device SV transmits (transfers) the control request message received and held from the mobile phone MP to the equipment device controller C1 (8). In the equipment device controller C1 that has received this control request message, the equipment device controller control section 10 turns off the lighting equipment (facility equipment X2) by turning off the relay of the relay terminal section 15 via the lighting equipment interface section 14. 9). Thereafter, the equipment device controller control unit 10 creates a control response message indicating that the lighting equipment (facility equipment X2) has been turned off and sends it back to the center apparatus SV (10). The control response message is transferred from the center device SV to the mobile phone MP (11), and it is confirmed that the lighting fixture is turned off by displaying the control response message transferred from the sensor device SV on the liquid crystal screen of the mobile phone MP. it can. However, when it takes a considerable time (for example, several minutes) from sending the control request message to returning the control response message, a message indicating that the control request message has been received is sent from the center device SV to the mobile phone MP. It is desirable to send.

  Next, in the security system (subsystem SS2), the operation when the security controller C2 obtains detection information indicating the occurrence of an abnormality (for example, the occurrence of a fire or gas leak or the entry of a suspicious person) from the security receiver SR. This will be described with reference to the sequence diagram of FIG.

  When an abnormality is detected in any one of the security devices Y1 and Y2, and the security controller control unit 30 of the security controller C2 acquires detection information on the occurrence of the abnormality from the security receiver SR (1), the security controller control unit 30 detects the detection information. A response message (hereinafter referred to as a linkage message) including the message is generated and transmitted to the IP addresses of predetermined counterparts (for example, the equipment device controller C1 and the display control device CV) (2) and the center device A message for reporting the occurrence of an abnormality is also sent to the SV (3).

  In the display control device CV that has received the cooperation message, the microcomputer unit 50 determines the content of the abnormality (for example, the occurrence of a fire or gas leak or the entry of a suspicious person) from the detection information included in the cooperation message received. , The alarm sound corresponding to the content (for example, a voice message such as “A fire has occurred. Please evacuate immediately.” Or “A suspicious person has entered.”) An alarm display corresponding to the content of the abnormality (for example, a message such as “A fire has occurred at XX” or “A suspicious person has entered XX”) is displayed on the liquid crystal display of the display unit 52 ( 4).

  In addition, the center device SV notifies the householder who is out of the house by sending the report message of the occurrence of abnormality received from the security controller C2 to the mail address of the mobile phone MP registered in advance (5). .

  On the other hand, in other controllers that have received the cooperation message, that is, the equipment device controller C1 and the image transfer controller C3, generated from the detection information included in the cooperation message received by the equipment device controller control unit 10 and the image transfer controller control unit 40. The content of the abnormality is judged, and a control operation according to the content of the abnormality is executed if necessary according to a predetermined rule (6). For example, when a fire is occurring, the facility device controller control unit 10 can turn on the luminaire to facilitate evacuation. However, when a gas leak has occurred, if the operating state of the equipment Xm is switched, there is a risk that the spark generated when the power is turned on or off may ignite the leaked gas. Then, even if a control request message is received, the control for all the equipment devices Xm is invalidated. Alternatively, when a suspicious person enters, the image transfer controller control unit 40 acquires image data obtained by imaging the monitoring area from the network camera NCm, and transfers it to the center device SV together with the suspicious person's intrusion information. A person can check the image of the monitoring area using the mobile phone MP.

  Next, the image captured by the intercom system (subsystem SS3) door phone slave unit DS is stored in the center device SV and the stored image is played back by the terminal device (for example, the mobile phone MP). This will be described with reference to the sequence diagram of FIG. However, in the following description, a case where only an image is stored will be described, but a call voice can be stored in the center device SV together with the image and can be reproduced by the terminal device.

  As described above, when the visitor presses the call button (1), the image transmission function of the doorphone slave unit DS is enabled, and the image (image data) captured by the camera of the doorphone slave unit DS becomes the interphone parent. To the machine IM. The intercom master unit IM transmits the image data received from the door phone slave unit DS to the image transfer controller C3 (2). In the image transfer controller C3, the image data received from the interphone master unit IM is compressed by the image transfer controller control unit 40 using a predetermined compression method (for example, MPEG4 for moving images, JPEG for still images). (3) The compressed image data is transferred as a response message to the center apparatus SV through the home network and the external network (4). The center device SV records (accumulates) the image data received from the image transfer controller C3 on a recording medium such as a hard disk (5).

  Further, when the answering function of the interphone master unit IM is enabled by the display control device CV via the image transfer controller C3 (6), the answering device setting is notified from the display control device CV to the center device SV. A message is sent (7). Then, when the visitor presses the call button when the answering machine function is set to be effective (8), the image transmission function of the doorphone slave unit DS is enabled and the image is captured by the camera of the doorphone slave unit DS. The image (image data) is transmitted to the interphone master unit IM, and the interphone master unit IM transmits the image data received from the door phone slave unit DS to the image transfer controller C3 (9) and the image data to the memory unit 45. Store (record) (10). The image data received from the interphone master unit IM is compressed by the image transfer controller control unit 40 (11), and the compressed image data is transferred as a response message to the center device SV through the home network and the external network (12). .

  In the center device SV, when the image data is transferred from the image transfer controller C3, a message is sent to the e-mail address of the mobile phone MP registered in advance to notify the resident who is out (13), and The image data is stored in a recording medium (14).

  When the householder who has received the message wishes to confirm the visitor, the mobile phone MP may transmit an image reproduction request message to the center device SV (15). The center device SV that has received the request message processes (converts) the image data stored in the recording medium into a file format that can be played back by the mobile phone MP (16), and transmits the processed image data to the mobile phone MP. (17). As a result, the housekeeper who is out can check the visitor by viewing the image reproduced by the mobile phone MP.

  Next, an operation when the security controller C2 is used as a proxy server device and an image captured by the network camera NCm is displayed on a terminal device (for example, a mobile phone MP) will be described with reference to the sequence diagram of FIG.

  When a request message for an image monitor is transmitted from the mobile phone MP to the center device SV (1), the center device SV is polled by the security controller C2 of the security system SS2 (2). The transmission request message for the web page for the image monitor that is held is transmitted to the security controller C2 (3). In the security controller C2 that has received the request message, the security control unit 30 reads the web page for the image monitor stored in the memory unit 35 and transmits it from the LAN interface unit 31 to the center device SV (4). The image monitor web page displays, for example, a list of names of icons assigned to all network cameras NCm existing in the home network in a predetermined order. It is transferred to the MP (5) and displayed on the liquid crystal screen by the web browser of the mobile phone MP. Then, if the user operates the cellular phone MP to select the icon of the name of the network camera NCm that desires to monitor the image, the selection result is transmitted to the center device SV (6), and further the security is sent from the center device SV. An image monitor request message including the selection result (name of the selected network camera NCm) is transmitted to the controller C2 (7). Upon receiving this image monitor request message, the security controller control unit 30 of the security controller C2 transmits an image data acquisition request message via the home network with the IP address of the network camera NCm to which the name is assigned as the destination (8 ), The image data captured by the network camera NCm that has received the request message is transmitted to the security controller C2 (9). In the security controller C2, the image data received from the network camera NCm is transferred as a response message to the center apparatus SV through the home network and the external network (10). Then, the center device SV transmits the transferred image data to the mobile phone MP (11), and as a result, the image captured by the network camera NCm can be displayed and confirmed on the mobile phone MP.

  Next, the point which becomes the summary of this invention is demonstrated.

  In the system according to the present embodiment, the security system SS2 and the network camera NCm are linked to each other, and security data that is a proxy server device is image data of a monitoring area captured by the network camera NCm when an abnormality is detected by the security devices Y1 and Y2. It can be acquired by the controller C2 and transferred to the center device SV together with the abnormality detection information. Therefore, when the security system SS2 exists as a subsystem, the security controller C2 is preferentially set as a proxy server device. For example, in the situation where there is no security system SS2 at first and the equipment device controller C1 is operated as a proxy server device, and the security system SS2 is newly added to the system configuration, the network camera NCm The proxy server device is changed from the equipment device controller C1 to the security controller C2. When the proxy server device is changed in this way, the changed proxy server device (in the above example, the security controller C2) searches for the network camera NCm connected to the home network using the UPnP control point function. The device information is acquired and the network cameras NCm are managed in the order in which the device information is acquired. Therefore, when the proxy server device before the change (in the above example, the equipment device controller C1) is managing, There is a possibility that the order and the order of the network cameras NCm managed by the changed proxy server device are different. For example, when the equipment controller C1 is a proxy server device, the names “living room” and “entrance” are assigned to the network cameras NC1 and NC2, respectively, and the list display order is No. 1 and No. 2. In this case, the proxy server device may be changed to the newly added security controller C2, and the order of the list display of the network cameras NC1 and NC2 may be switched between the second and first. If the order of the network cameras NCm changes due to the change of the proxy server device in this way, the order of the list display of the image monitor web pages transferred from the center device SV to the mobile phone MP is also changed. There is a risk that convenience for the user may be reduced.

  Therefore, the controller serving as the proxy server device transfers the device information (IP address, name, list display order, etc.) of the network camera NCm to the center device SV, holds the device information in the center device SV, and newly When another controller added to the system becomes a proxy server device (when the proxy server device is changed), the center device SV is transferred from the proxy server device before the change via the external network and the home network and retained. If the device information of the network camera NCm that has been transferred is transferred to the changed proxy server device, and the changed proxy server device manages the network camera NCm with the device information transferred from the center device SV, before and after the change of the proxy server device The network camera NCm list display order is different There is no. As a result, the order of display of the list of image monitor web pages transferred from the center device SV to the mobile phone MP does not change before and after the change of the proxy server device, so the convenience for the user is not lowered. The change of the proxy server device is such that when the new controller is added to the system, the center device SV automatically stops the proxy server function of the controller before the change and starts the proxy server function of the controller after the change. Alternatively, the contractor may manually stop and start the proxy server function when adding a new subsystem.

  Alternatively, the order in the list display of the names of the network cameras NCm in the image monitor web page transferred from the controller serving as the proxy server device is stored in the center device SV, and the image monitor for the image monitor transferred from the changed proxy server device If the order in the list display of the names of the network cameras NCm on the web page is different from the order before the change, the center device SV corrects the order before the change, and the corrected image monitor web page is stored in the mobile phone MP. If transferred, the order of the list display of the web page for the image monitor does not change before and after the change of the proxy server device, and the convenience for the user is not lowered.

  Further, the order in the list display of the names of the network cameras NCm is stored in the center device SV in the image monitor web page transferred from the controller serving as the proxy server device, and the image monitor for the image monitor transferred from the changed proxy server device. When the order in the list display of the names of the network cameras NCm on the web page is different from the order before the change, the center apparatus SV corrects the order before the change and transfers it to the proxy server apparatus after the change. If the server device corrects the list display order in the device information of the network camera NCm to the order received from the center device SV, the list display order of the network camera NCm will be the same before and after the change of the proxy server device. Convenience for the user is not reduced.
