In this embodiment, as shown in FIG. 1, the user accesses the management computer 3 from any one of the personal computer 14, the notebook computer 15, and the mobile phone 11 to access image data and sound from the monitoring terminal 1. The mobile phone 11 used in this embodiment has a relatively large display screen on which a monitoring image can be displayed, and performs decompression processing of the compressed data. It is supposed to be equipped with a possible microcomputer, and by connecting an earphone to the earphone terminal port 17, you can hear the sound while watching the screen You have me.
Hereinafter, the flow of the monitoring process in the monitoring system according to the present embodiment will be described with reference to the flowcharts of FIGS. 4 and 5. As described above, the monitoring sensor 90 is installed on the monitoring terminal 1 side. When 90 detects an abnormality as an external factor, the abnormality signal flows to the abnormality detection unit / call ID detection unit 91, and a call signal is output to the MPU 82. Here, the telephone number of the management computer 3 is registered in the MPU 82, and data obtained by imaging and sound collection by the monitoring unit 1 'together with dial-up are automatically transmitted to the management computer 3 as compressed data. . In this embodiment, when the monitoring sensor 90 detects an abnormality, the imaging and sound pickup device is activated. However, this imaging and sound pickup device is always in an activated state, and only the communication line is opened. May be. Of course, when the communication line is in a constantly connected state (ADSL, dedicated line, wireless Internet, CATV, etc.), the monitoring information obtained from the imaging or sound pickup device is transmitted to the management computer 3 only when an abnormality occurs, for example, by packet communication. You can also.
When the management computer 3 receives the monitoring information and / or the information indicating that there is an abnormality, the monitoring information is temporarily stored here. This monitoring information is particularly preferably an image taken by the imaging device, and this image is taken into the management computer as primary monitoring information. In the case of self-transmission due to intrusion of, for example, a thief, there is a high probability that the thief will appear. . Here, the management computer 3 receives the telephone number of the router 2 sent together with the monitoring information, confirms that this is information for which registered user, and then the management computer 3 A method is used to notify the contracted or registered user that some abnormality has occurred. It should be noted that the management computer 3 checks which monitoring terminal has transmitted the information by telephone number. If the monitoring terminal has a fixed address (such as a global ID), the management computer 3 can check the fixed address on the Internet. Is clear.
To elaborate,
a. Receiving primary monitoring information transmitted by a self-transmission function of the monitoring terminal via a communication line, and confirming which monitoring terminal the primary monitoring information is from;
b. Temporarily storing the primary monitoring information so that it can be viewed or transmitted;
c. Searching for associating this primary monitoring information with a user that is registered in the database in advance;
d. Performing a notification to the user that there is transmission information, if a corresponding user exists;
e. Confirming whether or not this user is a user who is qualified to view the primary monitoring information by performing authentication for requesting an ID, a password, and the like to the accessing user; and ,
f. If the user is a user who is qualified to browse the primary monitoring information, the primary monitoring information is given a viewing permission to the information terminal of the user, or is sent to a server capable of browsing. Transmitting.
Therefore, in this system, when a monitoring terminal installed in a specific area sends monitoring information through a communication line network by its self-transmission function due to some kind of abnormality or detection of a signal, the management computer starts the first operation. The secondary monitoring information is temporarily stored so that it can be viewed or transmitted, and the monitoring terminal that sent the primary monitoring information is confirmed by a telephone number such as a router, and the corresponding user is used from among many registered users. The user is searched for and selected, and the user is notified that the transmission information is available, so that the authorized user who has been authenticated can access the management computer 3 only by accessing the management computer 3. Can be easily browsed.
This notification method is preferably an e-mail or a call. It is preferable that the e-mail and the call are sent to the user at predetermined time intervals, and the notification is terminated when the user requests the monitoring information. According to this example, when the user cannot answer the telephone for some reason, the data of the primary monitoring information remains on the management computer 3 side, so that the user can use the data whenever the cause disappears. Obtain monitoring information.
That is, when the user obtains some notification data, the user accesses the management computer 3 owned by the monitoring service provider from, for example, the mobile phone 11 owned by the user, and enters his / her user ID according to the guidance. The user inputs the password by operating the mobile phone 11.
On the management computer 3 side, the user ID and password transmitted from the mobile phone 11 of the user are compared with the registration data of the user DB stored in the storage device 35, and the comparisons match. When it is determined that the user is an authorized user, the compressed data including the image and the sound transmitted from the monitoring terminal 4a is temporarily stored (stored) in the storage device 35, and is, for example, an information terminal of the user. The primary monitoring information, which is the compressed data temporarily stored (stored), is converted to an appropriate file format, for example, C-HTML and transmitted to the mobile phone 11. Here, the term “transmission” includes the meaning of browsing, and changes the type of image frame or the compression method depending on the type of the mobile phone or the type of the personal computer, and transmits the image. Also, at the request of the user, the primary monitoring information can be transmitted to the server of the provider, which is the storage location of the mail. The various communications between the mobile phone 11 as the information terminal and the management computer 3 are all recorded in the communication history recording unit of the recording device 35 and remain.
Since the user who has accessed has already been authenticated to request an ID, a password, etc., and has been found to be a user who is qualified to view the primary monitoring information, the management computer 3 Then, a menu is displayed to ask the user whether to request the current monitoring information (secondary monitoring information).
Subsequently, when the user wants to see the current state of the home or the like where the monitoring terminal 1 is installed at a place where he or she is away, the user makes a request for the second monitoring information according to the guidance. In response to the user's request, the management computer 3 accesses the monitoring terminal that has transmitted the primary monitoring information via the communication network, and obtains a substantially real-time specific area obtained from the monitoring terminal. It receives certain secondary monitoring information and gives the user's information terminal permission to view the information, or transmits the information to a server or the like that can view the information. For this reason, for the user, in addition to the primary monitoring information obtained at the time of abnormality or the like, the current secondary monitoring information after a predetermined time has passed after the notification is obtained, so that the information amount as the monitoring information is obtained. Becomes enormous.
In order to obtain the secondary monitoring information, the management computer 3 side monitors the monitoring terminal registered in the user DB in association with the user ID, in this case, the monitoring terminal that transmitted the primary monitoring information. A call is made to a telephone number (ISDN line) of the router 2 constituting the terminal, for example, the monitoring terminal 4a. The terminal adapter section 81 is provided with an abnormality detection section / call ID detection section 91 for receiving a telephone number of the management computer and the like, and is configured to output a call command to the MPU 82 therefrom.
At this time, at the time of calling, the telephone number data of the management computer 3 as the caller is transmitted to the router 2 together with the call signal by the exchange of the communication network 5.
Based on the reception of the call signal, the router 2 compares the caller telephone number data transmitted together with the call signal with the telephone number of the management computer 3 registered in the internal ROM of the MPU 82 in advance. When the telephone numbers match, a call is made to open a communication line, and predetermined start command data is sent to the monitoring unit 1 '.
Based on the reception of the predetermined start command data, the MPU 65 of the monitoring unit 1 'starts up the DSP 56 which performs data compression processing with the PCM codec 52 together with the monitoring CCD camera 55 and the sound collecting microphone 53 which are monitoring means. .
As described above, in the present embodiment, by activating the monitoring means such as the monitoring CCD camera 55 by receiving the activation command data, the power consumption of the monitoring unit 1 'can be significantly reduced. However, the present invention is not limited to this. When the power consumption of these monitoring units is small, or when sufficient power can be supplied as the operation power of the monitoring unit 1 ′, etc. Alternatively, the monitoring means of the monitoring unit 1 'may be kept operating at all times.
In response to the completion of the connection of the communication line due to the incoming call, the monitoring unit 1 ′ receives the image data captured by the activated monitoring CCD camera 55 and the sound collected by the sound collection microphone 53 and is transmitted by the PCM codec 52. The digitized sound data is converted into compressed data by the DSP 56 according to a predetermined data compression method, for example, the MPEG method, and the compressed data is sent from the communication unit 60 to the router 2, and the monitoring communication line board is sent from the router 2. It is sent to the management computer 3 through 38.
The compressed data including the image and the sound transmitted from the monitoring terminal 4a is temporarily stored (stored) in the storage device 35, and is temporarily stored (stored) in the user's information terminal, for example, the mobile phone 11. The compressed data is converted into an appropriate file format, for example, C-HTML and transmitted. Here, the current monitoring information may be requested any number of times in the connection state. The various communications between the mobile phone 11 as the information terminal and the management computer 3 are all recorded in the communication history recording unit of the recording device 35 and remain.
The converted data including the compressed data transmitted to the mobile phone 11 which is the information terminal of the user is appropriately decompressed and the image data is displayed on the display screen, and the sound data is D / A converted and the sound data is D / A converted. It is output from the earphone terminal port 17. At the same time, a history of at least the transmission process performed by the management computer 3 to the user up to now is sent to the user's information terminal in a time-series manner, and the legitimate user associates with his / her own schedule to make unauthorized use by a third party. You can check if there is no access.
When the monitoring of the user is completed and the user terminates access to the management computer 3, the management computer 3 disconnects the communication line with the router 2 without delay. The monitoring unit 1 ′ stops the PCM codec 52 and the DSP 56 that performs the data compression process together with the monitoring CCD camera 55 and the sound collecting microphone 53 that have been activated as described above, and shifts to the sleep state of stopping or semi-stopping. The power used in the monitoring terminal 1 is reduced as much as possible. By doing so, the frequency of replacing the battery 67 can be greatly reduced.
In addition, the user can obtain not only the transmission history but also various types of history information, and may request transmission of only this transmission history, not the time of transmission of the monitoring data, after authenticating the user. .
As described above, the present invention has been described with reference to the drawings. However, the present invention is not limited to these embodiments, and it goes without saying that changes and additions without departing from the spirit of the present invention are included in the present invention. .
For example, in the above, the router 2 and the management computer 3 that constitute the monitoring terminal, and the mobile phone 11 that is the information terminal of the user are connected via the communication network 5, but the present invention is not limited to this. Instead, the communication network 5 may be an Internet network, which is a computer network.
Further, in the above embodiment, the monitoring terminal is constituted by the monitoring unit 1 'and the router 2, but these may be accommodated in one housing to constitute the monitoring terminal.
In the above embodiment, one monitoring unit 1 ′ is connected to the router 2. However, the present invention is not limited to this, and a plurality of monitoring units 1 ′ may be connected to the same router 2. You may do it.
