Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transfer apparatus and method applicable to a remote monitoring system and the like, and more particularly, to a remote monitoring system using a device capable of analyzing and processing data from home appliances and sensors in a home. If it is determined based on the analysis result that the status is “unusual”, the present invention relates to an information transfer service for notifying “unusual” to a plurality of destinations and giving priority to video transfer.

[0002]

2. Description of the Related Art There are various types of conventional monitoring services, such as (1) watching type, (2) crime prevention and accident prevention type, and (3) unexpected situation response type.

[0003] As a specific example of the above (1), by attaching a sensor to an electric water heater and grasping the use situation, the living situation of a family living alone in a remote place is grasped by e-mail or the like (http: //www.mimamori.net/ Hereafter, a conventional example 1) is known.

[0004] As a specific example of the above (2), a sensor is installed at a place where a third party can invade such as a window of a house or a place where a fire may occur such as a gas appliance, and based on abnormality information of the sensor. A service car goes to the contractor's house (for example, http: // ww
w.secom-sanin.co.jp/index.html Conventional example 2),
As a specific example of (3), sensors and video cameras are installed at necessary places in the house, and an intermediate management facility called a regional data center is installed based on an algorithm that determines whether living is safe. To set up an emergency call window,
Make a dial-up connection and notify in an emergency (for example,
JP-A-2001-195678, hereinafter referred to as Conventional Example 3),
and so on.

A medium for transmitting these services is a general-purpose telephone line in Conventional Example 1, and a dedicated line (or general-purpose telephone line) in Conventional Example 2.
IP network is also planned), and since conventional example 3 is a general-purpose telephone line or dedicated line and the bandwidth is narrow and expensive in any case, the contents of information to be transmitted are text-based in conventional example 1, conventional example 2, In No. 3, video information can be viewed only in an emergency in case of emergency alarm information and privacy protection.

[0006] In recent years, with the adoption of broadband and flat-rate subscriber lines, it has become possible in the era to transmit a video having a large amount of information at a lower price than a voice through a general-purpose IP (Internet Protocol) network. It has become. Therefore, if conventional examples 1 to 3 also use a general-purpose IP network,
Network costs can be kept low. Along with this, as a service that replaces Conventional Example 1, it is possible to install a video camera at the home of a single person living in a remote place (elderly people, students, and single employees), and watch over with video information.

Further, by installing a wireless device at the subscriber's home and expanding the communication environment outside the subscriber's home, it is also possible to collect and confirm information on his / her own home when he is away. This case corresponds to the case where the information sender and the information receiver are the same.

[0008] As described above, 24 hours video is always connected.
Although it is technically possible to transfer time, for example, if a family living in a remote place is an elderly person living alone, the family can keep watching the video 24 hours a day to monitor their lives in case of unexpected situations. Is difficult in practice.

[0009] If it is desired to monitor the whole life, the monitored party must individually make settings for information transfer in the above-described conventional examples 1 to 3, but in such a case, the setting is complicated.

[0010] In the case of the watching type service of the above-mentioned conventional example 1, it is necessary to constantly transfer the video.
In the case of a security-enhanced service such as an unforeseen event, the monitored party may not want to transfer video other than in an emergency from the viewpoint of privacy protection. In other words, if it is desired to monitor the whole life, it is necessary to determine whether or not to transfer the video according to the service type and the state of the monitored side, and the home controller and the network-side management server need control for that. However, it has not been realized at this time.

[0011]

In the above conventional examples 1 to 3,
When a general-purpose IP network is used instead of a dedicated line, there are the following problems. That is, since the IP network is operated by a mechanism that performs transfer on a best-effort basis, information does not always arrive within a time when information makes sense as information. In that case, IETF
(Internet Engineering Task Forces) standardizes the protocol of the IP network, and guarantees the bandwidth. RSVP (ReSource Reservation Protocol RFC220)
7) It is possible to send information reliably within a predetermined time by establishing an end-to-end connection that considers QoS (Quality of Service) such as delay by using, etc., but actually transmit the video Immediately before the time you want to use, the bandwidth you want to use is not always free depending on the network operation status.
If it is not empty, the bandwidth is not guaranteed, and there is a problem that the information can not be reliably transmitted.

[0012] Alternatively, it is possible to own the band by continuing the connection over the IP network for 24 hours, but in this case, there arises a problem that the usage fee of the network user increases.

Accordingly, the present invention has been made in view of the above problems, and sets a plurality of receiving destinations specified by an information sender, and stores the information of the sender according to the service selected by the sender. The first object is to provide an information transfer service by priority transfer at a timing required by the caller,
Further, a second object is to provide an information transfer service in a priority mode when it is determined that the priority transfer is not normal (normal) based on an automatic analysis processing algorithm such as a sensor or home appliance information. A third object of the present invention is to provide a service registration processing function for performing information processing and to provide an information transfer service that can be set by an information sender.

[0014]

According to the present invention, information is acquired from information collecting means for collecting video information on the information transmitting side and detection information relating to life, and it is determined whether or not the information has an abnormality. And, when an abnormality is determined, the information receiving side is provided with a transfer unit that selects at least video information from the obtained information, and transfers the selected information to a predetermined destination via a network. Only when there is an abnormality, the information including the video information is transferred to a predetermined transfer destination via the network, and when there is no abnormality, the detection information is transferred to the network.

[0015]

According to the present invention, remote monitoring of the information transmitting side is always performed based on the information detected from the transmitting side, and if there is an abnormality in the detected information, the video information is transmitted to a predetermined distribution destination (for example, security). To the company), reducing the load on the network and the burden on using the network,
Necessary video information can be transferred preferentially, and anomalies can be accurately reported.

[0016] Then, the network provider that provides the service can provide the value-added service to the subscriber, and obtains the usage fee in addition to the fixed fee for the constant connection. In addition, a security company or the like can expand services for general homes without increasing equipment costs and personnel costs by contracting with a network provider that provides the information transfer service environment. By registering the monitoring service, the service provider mediates information transfer to multiple destinations, enabling batch registration.This reduces the labor involved in monitoring contracts and reduces the “watch-over” type to “ Prevention "and" Contingency "models,
It is possible to receive a detailed information transfer service at a lower price than the conventional price.

[0017]

When one of the plurality of recipients is a family member, the receiving terminal 2-18 (see FIG. 2) transmits the notification information to a personal computer (computer) or an Internet TV.
20 may be used as a display. Alternatively, when the information recipient goes out, the notification packet may be transmitted to the mobile terminal device and replaced with a ring tone of the mobile terminal device.

FIG. 4 is an example of a service transition diagram according to the present invention.

The information sender 1-1 sends a service contract request 4-1 to the service provider 1-2 together with information on an information receiving destination and a service type (setting at the time of information transfer). The provider 1-2 that has received the request 4-1 sends a service contract confirmation 4- to the information receiver 1 and the information receiver 2 based on the destination information.
Perform steps 1 and 4-2.

The above operations 4-1 to 4-3 are performed on the WEB of the service provider, and the actual processing is performed by the user registration unit 2-
12-2 (FIG. 3).

FIG. 1 shows a display screen image at the time of user registration.
It is shown in FIG.

Upon confirmation from the information receivers 1-3 and 1-4, the service provider 1-2 makes a service setting notification 4-4.
Is performed for the information sender 1-1. FIG. 15 shows a display screen image diagram after the service registration. The information such as the service type (whether or not video transmission is always performed) and the transfer mode is set to the priority mode or the normal mode is indicated by the information sender 1-.
It is displayed on the TV 2-4 on the first side.

The service user can switch the mode to the priority mode based on the collection of in-home information described later, and can directly change the mode from the setting screen shown in FIG.

FIG. 5 shows a specific processing flow at the time of service registration, the contents of which will be described later.

Next, in FIG. 4, after the service setting notification, as soon as the home network environment for the monitoring service in the information transmitter home 2-1 (FIG. 2) is set, the information transmission of the information transmitter home is performed by the home controller. 2-8 (Fig. 3)
Is started through the control unit 2-8-1 (FIG. 3) in (4-5-1).

Here, the contents of the information transfer include at least three types of home appliance information and sensor information connected to the home and video information from the surveillance camera. 3), sensor group storage section 2-8-3
(FIG. 3), these information groups are stored in the video information group storage unit 2-8-4 (FIG. 3) and processed by the control unit 2-8-1.

The home appliance information and the sensor information (detection information)
This is information necessary for automatically analyzing information relating to the life of the information sender and determining the timing of switching to the priority mode. The information related to life is transferred from the control unit 2-8-1 (FIG. 3) to the management server 2 at predetermined time intervals or the like.
.., 4-5-n. Note that, while the analysis result determination is in the normal mode in the data processing unit 2-12-6 (FIG. 3) of the management server, continuous processing is performed. In addition, the information related to life is a usage state of home appliances, a detection signal of a sensor, and the like, as in the conventional example,
This is information that requires a narrower information transmission band than video information obtained from a surveillance camera or the like.

Management server 2-12 that has received the home information
In FIG. 3, data distribution 4-6 is performed depending on whether the information is for analysis or video information, and data analysis is started for data for analysis (4-7).

The video data is transferred only to the information receiver 1 and, if necessary, the information storage unit 2 of the management server 2-12.
12-4.

When it is determined based on the analysis result of the analysis data that the mode of the information sender and the home of the sender has shifted from the normal mode to the priority mode (a state in which an abnormality is determined), the mode is switched to the priority mode 4-9. The transfer process 4-10 is started.

Switching from the normal mode to the priority mode is performed when the detected information is determined to be abnormal (not normal) by the above-mentioned automatic analysis processing. As in the electric water heater described in the above-described conventional example, when the home appliance is switched on and the idle time exceeds a predetermined value, it is determined that the home appliance is not normal (abnormal). (Eg, air conditioner, lighting, TV, etc.) for a predetermined time (eg,
For example, if the system is in an operating state for more than one night, it may determine that it is not normal and send an alert signal, and information detected from home appliances or information detected by sensors (detection information , Life-related information).

In the priority transfer processing, the priority mode notification signal 4
Video information 4-13 and 4-14 are transmitted to the information receiver 1 and the information receiver 2 together with -11 and 4-12. The information receiver 1 and the information receiver 2 that have received the information confirm the video information, and if necessary, perform two-way communication and execute necessary processing.

FIG. 5 is a processing flow chart at the time of a service contract according to the present invention, and FIG. 6 is a processing flow chart in providing a service according to the present invention. FIG. 5A shows the normal mode, and FIG. This corresponds to the mode.

(a) Normally, (b) It is a figure which shows priority time. Hereinafter, FIG.
Further details will be described with reference to FIGS.

In FIG. 5, when a service request is issued from a certain user, the user registration unit 2-12-2 (FIG. 3) performs service user authentication, and the service requesting user provides a service. It is confirmed whether or not the user is a network operator (5-2). If the user is not a user, the request is rejected (5-3). If the user is confirmed, the user is designated as an information receiver. Thereafter, destination authentication is performed (5-4). If the user is not a user, the request is rejected (5-4).
-5) If authentication is confirmed, information sender registration is performed together with service type designation confirmation (5-6).

The service user retrieves from the user database whether the information distribution service is already used (5-7). If the database exists (5-8), the database does not exist in the database. A new database is created (5-9), and service registration such as destination and service type is performed (5-10).

The above processing is performed by the management server 2-12 (FIG. 3).
In the user registration unit 2-12-2 (FIG. 3).

After the above service registration, the necessary devices such as sensors and video are set, and then the service is started.

Next, the processing flow after the service contract is shown in FIG.
This will be described with reference to FIG.

FIG. 6A corresponds to the normal mode, and FIG. 6B corresponds to the priority mode.

The information packet from home 2-1 registered as information sender 1-1 after the service contract is sent to control unit 2-8.
-1 (FIG. 3) is transmitted to the management server 2-12 (FIG. 3).

The management server 2-1 that has received the information packet
2, the input / output interface unit 2-12-1 (FIG. 3)
Referring to the registered user information table 2-12-5 (FIG. 3), based on the information sender address information of the arriving packet,
After confirming the registration, it is determined whether or not the arrival address is video information (6-2).

After this determination, the specified address and service type of the video information are confirmed based on the registered user information table 2-12-5 (FIG. 3) (6-3). FIG. 7 shows an example of the registered user information table, and FIG. 8 shows an example of the normal mode change table.

The registered user information table 2-12 shown in FIG.
5 is the service user address, the controller 2-
8 are set, the service user contact address is registered as the service user (information sender 1) device IP address (here, the address of the controller 2-8), and the designated address is registered. A service type is set for each of the addresses of the information receivers 1 and 2 and the management server 2-12, and for each of these designated addresses. For example, the service type a in FIG. The service type “b” always transmits video data.

Then, the mode change table 12- in FIG.
7-1 shows a normal (normal) state, in which the address of the service user (information sender) is set as the source address, and the registered user information table 2- is set as the destination address corresponding to this source address. The designated address set in 12-5 is set. In the processing for each destination address in the figure, the processing content according to the service type in the registered user information table is set. In the normal state, the flag is reset (= 0), and the service type b
The video data is output (transmitted) only to the destination address.

The registered user information table 2-12-5
, And if the video data transfer is a service type of OK, refer to the corresponding mode change table, write the normal-time sender address in the destination portion of the header portion of the packet, and transmit (6-4). .

In the case of the service type in which the video data is not normally transmitted, the service user searches whether or not to store the video data, and if the video data is to be stored, the user data registration unit 2-12-4. Applicable area 2-
If information is to be recorded in 12-5 or not to be recorded, the video data is rejected.

The above processing is performed by the data processing unit 2-12-6 of the management server 2-12.

On the other hand, if the packet received by the management server 2-12 is analysis information, data analysis is performed (6
-9), it is determined whether or not it is normal (6-10).

If it is normal, the user data is updated (6-11). If it is determined that it is not normal, a notification indicating that it is not normal is transmitted to the server control unit 2-12-3 together with the information sender destination information. I do.

The server control unit 2-12-3, having received the notification that the status is not normal, refers to the table in the priority mode in the mode change table 2-12-7 (6-13).
DSCP value (Differentiated Service Code) of the packet
Point) is rewritten (6-14), and the priority notification signal is transmitted at the same time as transmitting the destination to all registered information receivers (6-15).

After the step (6-15), the packet of the information sender destination address transmitted is copied by the server controller 2-12-3 for a plurality of registered sender destination addresses. Is rewritten to a plurality of sender addresses and transmitted.

FIG. 9 shows an example of the mode change table at the time of priority. In the priority mode, the flag that has been reset in FIG. 8 is set (= 1) to the flag corresponding to the source address (information sender) where abnormality (an unusual state) is detected, as shown in FIG. Then, the video data from the source address is transmitted to the destination address with the flag set.

FIG. 10 shows an example of Diffserv setting in the management server 2-12 of the present invention. FIG. 10A shows the normal mode, and FIG. 10B shows the priority mode.

Assuming that the video information transmitted from the information sender is image 2, in the normal mode shown in FIG.
3 shows that the quality of the classification of the image 2 located in Drop 2 is rewritten to Class 1 in the priority mode, and the priority of the image 2 is dynamically changed to the highest Class 1 in the priority mode. The bandwidth of the image data directed to the receivers 1 and 2 can be guaranteed.

FIG. 11 is an example of a service transition diagram when the information sender moves from home to outdoors.

When moving outside, the information sender 1-1 presses the terminal switching button of the controller 2-8 (11-
1) Send a switching notification (11-2).

The service provider 1-2 that has received the switching notification
(Management server 2-12) registers the registered user information table 2
The source address in the mode change table 2-12-7 is registered with reference to the address used outside the home from-12-5. In this way, when the information sender is an elderly person, it is possible to realize monitoring of whereabouts to go, and in the case of a female student or the like, it is also possible to realize that a family member is monitoring the state of returning home when the return time is late.

When the user moves from home to outdoors, the information sender 1-1 transmits a movement notification to the service provider side, and the information receivers 1-2 and 1-3 perform information transmission by switching terminals. Even if the person 1-1 is away from home, it is possible to reliably obtain information.

Alternatively, the service provider may perform terminal switching based on the information registered in the service registration table by notifying the address of the mobile information device at the time of going out at the time of service registration.

FIG. 12 shows the second embodiment, and is an example of a service transition diagram in a case where a controller in an information sender's home controls Diffserv setting. The network 14
The router 2-13 disposed on the entrance side of the server has a Diffserv function as in the first embodiment.

In the first embodiment, the network 14
The priority of the packet to the information receivers 1 and 2 is controlled by the management server 2-12 disposed at the entrance of the information sender 1-1. However, in FIG. In this way, the video information data from the surveillance camera 2-2 and the data (detection information and life-related information) detected by the home appliances and sensors are sorted, the detection information is analyzed, the mode is switched to the priority mode, and the priority transfer process is performed. It is like that. In this case, the service provider manages contracts, user registration, and the like, and does not directly intervene in data transfer.

For this reason, as shown in FIG. 13, the controller 2-8 arranged in the house of the information sender 1-1 has:
A function for performing data analysis and data transfer processing provided in the management server 2-12 of the first embodiment is arranged.

That is, the control unit 2- of the controller 2-8
8-1 includes a user registration unit 2-12-2 and a data processing unit 2-12-6, and a controller 2-8 includes a registered user information table 2-12-5 and a mode change table 2-12. -12-7, and transmits the video information from the monitoring camera 2-2 (video information group 2-8-4) and replaces the detected information in place of the management server 2-12 of the first embodiment. It performs analysis and transmission of a notification (warning signal) indicating an abnormality, priority transfer processing of video information, and the like. The contents of the processing are the same as those of the management server 2-12 described in the first embodiment.

FIG. 16 is a processing flowchart when a path connection is set in advance.

When it is desired to reliably perform data transfer at the time of priority, it is more effective to use the above Diffserv setting and the following processing together.

After the service setting from the information sender 16-1 is completed, the service provider sets the logical path indicated by 16-6 from the information sender 16-1 to the information receiver 16-5. At this time, a minimum necessary band (information transmission band) value may be used, for example, a 64-byte band is secured.

In the normal state, the data distribution 16-8 and the data analysis 16-9 are performed in the same manner as described above. If it is determined based on the data analysis that the mode is the priority mode, the Diffserv is set based on FIG. 10 and the notification signal is transmitted based on the logical path secured at 16-6 in FIG. By this processing, the notification signal is preferentially transferred to the information sender 16-5.

Node 2 receiving notification signal (16-3)
Transmits a notification signal to the node 3 (16-4) (16-1).
6) At the same time, the free information of the bandwidth value on the exit side of the own node is transmitted to the node 1 (16-2) (16-18).

The node 3 (16-4) receiving the notification signal from the node 2 transmits the notification signal to the information receiver (16-
5) (16-17) and, at the same time, the bandwidth information on the exit side of the own node is transmitted to the node 2 (16-3) (16-19). The node 2 further transfers the band information to the node 1 (16-20).

The node 1 calculates a bandwidth value along the set path to the information receiver (16-5) based on the available bandwidth information of each exit node, and changes the bandwidth value to a changeable bandwidth value (16). -21).

By the above processing, the data transfer in the priority mode is more reliably performed (16-2).
2). Here, the path is RSVP or CR-LDP (Constr
aint-based Routing LDP) may be used. In addition, in preparation for a case where the bandwidth values of the nodes 2 and 3 are small, the mode is switched to the priority mode, and at the same time, the node 1 simultaneously performs a process of setting a different path from the nodes 2 and 3 to reach the information receiver. Is also good.

As described above, when it is desired to actually transmit video or audio, it is possible to secure a band required for transmitting video information at the entrance of the network, and to a plurality of destinations specified by the information transmitter. According to the service selected by the caller, it is possible to provide an information transfer service by preferential transfer of the information of the caller at a timing required by the caller, and furthermore, detection information from sensors, home appliance information, etc. Is determined to be unusual based on a predetermined automatic analysis processing algorithm, it is possible to reliably notify the information receiver including the video information set in advance in the priority mode. In addition, in the registered user information table 2-12-5 of the management server 2-12 or the controller 2-8, the information sender can set a service mode for automatically processing the priority transfer. When the sender is a security company, the information sender usually notifies only the information detected by the sensor, etc., and transmits the video information only at the timing desired by the information sender such as in an emergency (unusual case). Thus, it is possible to ensure the safety of life such as crime prevention or shortage while securing the privacy of the information transmitter.

Further, the management server 2-12 (or the controller 2-8) and the Diffserv function of the router 2-13 secure a wide band only when necessary, so that the load on the network and the information sender's The burden on network use can be significantly reduced,
Using the existing IP network, it is easy to ensure the safety of the life of the information sender.

The timing desired by the information sender can be set in two ways, that is, the case where the information sender determines and directly sets the timing, and the case where the information sender automatically sets the timing based on the determination of the automatic analysis processing such as sensor and home appliance information. is there.

In the above-described embodiment, the information detected by the home sensor and the home appliance is transmitted to the management server 2-12 via the controller 2-8. However, when the IPv6 is used as the IP network, A sensor or a home appliance may directly transmit information to the management server 2-12.
