TECHNICAL FIELD [0001] The present invention relates to a dynamic real-time monitoring service system and method using a sensor network,

The present invention relates to a remote monitoring service for an elderly person living alone to control an emergency situation by monitoring the occurrence of an event in a sensor network by forming a home sensor network using a detection sensor and transmitting the monitoring result to a remote site.

Due to the nuclear family and the aging of the elderly, there is an increasing number of elderly people living alone living alone. However, when the elderly living alone can not receive any help, sudden emergency situations arise, and immediate assistance is needed, or a device for life support is needed.

However, due to the lack of systematic and stable monitoring and lack of supportive devices, 24-hour residence support for elderly living alone is not possible, so it is impossible to monitor the residence situation and sometimes even after death several months, There are cases where the living environment is poor and is defenseless in emergency situations such as cold / heating, briquette gas, theft, and robbery.

In order to solve such a problem, a system for monitoring the situation of the elderly living alone at a remote place has been proposed. In the case of a single elderly man managed service method in the past, the elderly living alone is dialed to the manager phone immediately when an emergency occurs, A service capable of displaying information on an administrator terminal. For example, an alarm system for dialing a remote location based on a signal of a detection sensor and a detection sensor, a manager phone and a management server connected to the alarm system by a telephone network, and an administrator terminal connected to the management server, Service.

In the conventional method for managing the elderly people who are alone, the elderly person alone makes an emergency call or sends a DTMF signal to the management server based on a signal detected by the detection sensor, and the management server notifies the manager terminal of the DTMF signal. It is not a 24-hour real-time monitoring but a notification when a situation occurs. In addition, there is a problem in that there is a lack of a function of predicting analysis in advance so as to take preliminary action based on the monitoring state. There is a problem that it is inevitable to increase the cost due to the necessity of transmitting the information from time to time by using the charged remote communication.

Therefore, according to the present invention, when a sensor is installed in the vicinity of the observer and the observer, an event signal is generated when a predetermined condition is satisfied, and the generated event type is confirmed, and a specific number Recognizes the event type based on the reception number corresponding to the call and the caller number left in the reception number, and reports the event type to the monitoring service server linked with the alarm system through the network, When the emergency monitoring situation is required, we want to provide technology that can promptly respond to crisis situation of elderly living alone by inducing dispatch of emergency medical service by prompt detection and request.

In addition, the present invention can be applied to a case where status information for various event types is collected in a monitoring service server through short-range wireless communication, and a predetermined code corresponding to the corresponding status information is stored in a plurality of telephone numbers assigned to a Calling Identification Display (CID) So that it is possible to transmit various situation information to a management server at a remote site without expensive communication cost.

According to one aspect of the present invention, there is provided a dynamic real-time monitoring service system using a sensor network, comprising: an Infra Node for monitoring a specific event of an object distributed in a sensor network and transmitting the monitored event wirelessly; The method comprising the steps of: integrally managing events transmitted from the respective infrastructure nodes; confirming an event type transmitted from the infrastructure node; generating a call to a specific number corresponding to the predetermined code for each event type through a gateway; A control server for disconnecting a call from the control server, a control server for assigning a plurality of reception numbers for each event type of the sensor network, a reception number corresponding to the call received from the control server, and an event type generated in the sensor network through the call number of the call Monitoring and monitoring through the network A service server reporting the event type to at least two management servers interworking with at least two management servers through a network and reporting event types reported from the service server to at least two management servers interworking through a network, And a monitoring service server for collecting the collected information and providing the collected result to the predetermined portable terminal.

However, it will be readily apparent to those skilled in the art that the configuration according to the embodiments described herein may be applied to fixed terminals such as a digital TV, a desktop computer, and the like, unless the configuration is applicable only to a portable terminal.

Hereinafter, a dynamic real-time monitoring service system using a sensor network according to an embodiment of the present invention will be described in detail with reference to FIG.

1 is an overall configuration diagram of a dynamic real-time monitoring service system using a sensor network according to an embodiment of the present invention.

1, a system 100 to which the present invention is applied includes a user terminal 112, an access point (AP) 114, an infra node 116 A control server 118, a service server 120, a monitoring service server 122, first, second ... n management servers 124, 126 and 128, and a portable terminal 130.

The infrastructure node 116 monitors a specific event of the object distributed in the sensor network formed in the house 111 and causes a specific event of an object (e.g., a device or a person causing all situations including a gas appliance, a door, For example, by a door sensor 11, a motion detection sensor 12, a pulse wave sensor 13, a fire sensor 14, a gas sensor 15 and an on / humidity sensor 16 Each of the sensors forms a network with neighboring sensors on the basis of a preset sensor, and performs data transmission / reception for each network through the predetermined sensor.

2 is a block diagram illustrating the overall distribution structure of an infrastructure node in a network in a dynamic real-time monitoring service system using a sensor network according to an embodiment of the present invention. Referring to FIG. 2, Includes a lower sensor end node for detecting an access state, a health state, an activity state, and an ambient state of the object, and coordinates a sensor end node network by forming a network with at least two lower sensor end nodes, A plurality of coordinators 210-1, 201-2 ... 210-n for transmitting and receiving data and a plurality of lower sensor ends 210-1, 210-2 ... 210-n connected to the coordinators 210-1, A relay end node that bridges with another neighboring coordinator of the node and performs communication by arbitrating between the coordinator to which it belongs and another neighboring coordinator (Relay End Node, 216, 218).

When a predetermined packet is received from the neighboring coordinators 210-1, 210-2,... 210-n, the relay end nodes 216 and 218 transmit a plurality of subordinate sensor ends To the lower sensor node, generates an event of the packet, and transmits information of the generated event to its coordinator. For example, when an event is generated from an object located in a specific area, the relay end nodes 216 and 218 notify occurrence of an event to a plurality of lower sensor end nodes in the sensor network, At least one lower-level sensor end node that senses information about an event transmits to another neighbor coordinator using the relay end node without passing through a coordinator of its own network, To prevent weighting. As a result, even when the intra-network communication is temporarily weak or the access to the control server is not feasible, communication between a plurality of sensors of an infrastructure node having a role as a plurality of lower sensor end nodes, a plurality of coordinators and relay end nodes, In cooperation with communication with the control server or vice versa, weak events of objects are also detected, thereby enabling a more reliable real-time monitoring service.

Referring back to FIG. 1, the control server 118 communicates with the infrastructure node 116, unifiedly manages events transmitted from the respective infrastructure nodes, confirms the event type transmitted from the infrastructure node, Generates a call to a specific number corresponding to the predetermined code for each event type, and disconnects the call when the predetermined time is exceeded.

3, there is shown a configuration of a control server in a home network in a dynamic real-time monitoring service system using a sensor network according to an embodiment of the present invention. An event generated based on the sensing signal received from the infrastructure node 301 under the control of the control unit 306 and confirmed through the identification unit 302 and the event type confirmed through the identification unit 302 (CID server) 310 through the gateway 308 to generate a call. The control unit 306 checks a specific code matched with the identification ID for each lower sensor end node included in the sensing signal of the infrastructure node 301 stored in the matching unit 304 and a specific number corresponding to the specific code, And causes the gateway 308 to dial a specific number.

For example, if the identification ID of the lower-level sensor end node is an ID assigned to a door sensor, a call is made to a specific number, for example, 123-0001 corresponding to a code set in the door sensor, e.g., 01, It is recognized that an event related to a door has occurred in the house where the door is located. That is, the specific number refers to a number corresponding to each event among the reception numbers assigned to the service server, and the service server has three reception numbers 123-0001, 123-0002 and 123-0003, Assuming that 123-0001 corresponds to the door detection sensor, 123-0002 corresponds to the fire detection sensor, and 123-0003 corresponds to the gas detection sensor, if the calling number (CID) of 345-6789 is left in 123-0001 , The service server can confirm that the activity is detected on the door detection sensor on the caller side using 345-6789.

In addition, the control server 118 identifies the layered infrastructure node according to the determined priority in consideration of the absence of the observer and the specific state according to the time zone, and notifies the layered infrastructure node through the gateway And is directly routed to the monitoring service server 122 to request an emergency call service.

For example, it may be possible to identify the absence of a person to be observed at home through a motion detection sensor operating by a predetermined period, extend a sensing signal cycle of the infra-node in a specific time period such as a bedtime, The emergency call service is requested by controlling the gateway to directly connect to the monitoring service server, omitting the authentication procedure performed in connection with the call, considering the case where the emergency situation sensing signal of the emergency call is detected.

When a specific time notification event occurs, the control server 118 determines whether the operation of a predetermined device is performed through a lower sensor end node of the infrastructure node 116 using an API (Application Programming Interface) of the sensor network And an access point (AP) 114 for controlling the access point.

In this case, the API of the sensor network is a standardized API for interoperability among a plurality of digital devices existing in a network based on DLNA (Digital Living Network Alliance) middleware. The sensor network formed in the home according to the present invention includes various middleware (UPnP , Havi, Jini, VESA, DLNA ...) are used. The DLNA, which is one of the middleware, focuses on sharing all contents provided from devices such as a TV, a VCR, a digital camera, and an audio system And the control server 118 can control on / off of the digital device through the access point.

Referring again to FIG. 1, the service server 120 allocates a plurality of reception numbers for each event type of the sensor network and transmits the reception number corresponding to the call received from the control server 118 and the call number of the call Checks the event type generated in the sensor network, and reports the event type to the monitoring service server 122 linked through the network.

4, there is shown a configuration of a service server in a home network in a dynamic real-time monitoring service system using a sensor network according to an embodiment of the present invention. The service server 400 includes a controller 414 Receives a reception number corresponding to the received call including the identification ID from the gateway through the reception unit 410 and the originating number of the call, the service subscriber DB 412 confirms whether or not the subscriber is a monitoring service subscription member of the gateway identification ID And transmits the call connection acknowledgment message and the status information of the received gateway to the monitoring service server 122 when the identification ID is valid.

1, the monitoring service server 122 interworks with at least two management servers 124, 126, and 128 via a network to interwork with the event types reported from the service server 120 through a network 126, 128), collects results of information broadcasted through the associated management servers (124, 126, 128), collects the results, and transmits the result to a predetermined guardian To the portable terminal 130 of the administrator.

The management server 124, 126, or 128 is a server located in a municipality, a hospital, or a police station. By broadcasting a specific situation to each of the management servers 124, 126, and 128, .

The user terminal 112 includes an adaptive node unit that identifies a current network and can communicate with a plurality of lower sensor end nodes of an infrastructure node 116 located in the network, The integrated search of all the events occurring in the sensor network of the region where the sensor network is located can be performed in real time through the local transmission / reception module such as ZigBee.

Through this, a push service to the user terminal 112 through an SMS or notification occurs when a house event occurs, thereby enabling a bidirectional real-time monitoring service to the server 112 and the user terminal 112 that the user always possesses through the network.

Also, the user terminal 112 may access a network event through the adaptive node unit and receive a network event that is currently located in real time.

The configuration of the dynamic real-time monitoring service system using the sensor network according to an embodiment of the present invention has been described.

Hereinafter, a dynamic real-time monitoring service method using a sensor network according to an embodiment of the present invention will be described in detail with reference to FIG.

Referring to FIG. 5, in step 510, initialization of the entire sensor network is performed. In step 512, a specific event of the object is monitored through an infrastructure node distributed in the sensor network. In step 514, If a specific event is generated, the process proceeds to step 516, where it communicates with the infrastructure node and receives a specific event generated from a control server that integrally manages events transmitted from the respective infrastructure nodes, and confirms the corresponding event type.

If it is determined in step 517 that the corresponding event is not an event generated from the infrastructure node included in the predetermined priority level, the mobile node moves to step 518 and generates a call to a specific number corresponding to the pre- do. In this case, the predetermined priority level means a layered order determined in consideration of the absence of the observer and the specific state according to the time zone. For example, the presence of the in-house observation object is confirmed through the motion detection sensor operating according to the predetermined period A plurality of sensors are layered considering a case in which a sensing signal period of an infrastructure node is extended in a specific time period such as a sleeping time or an urgent situation sensing signal from a specific infrastructure node corresponding to a fire or gas sensing is detected.

In step 520, a time is checked while the call is generated, and when the predetermined time is exceeded, the call is disconnected in step 522 to leave a call number assigned to the gateway that originated the call.

In step 524, the service server confirms the event type generated in the sensor network through the reception number corresponding to the call received from the gateway of the control server and the call number of the call, and reports the event type to the monitoring service server linked through the network.

That is, the control server checks an event generated based on a sensing signal received from the infrastructure node, identifies a reception number assigned to a service server, for example, a CID server through a gateway according to the confirmed event type, Occurs. The control unit confirms the specific code matched with the identification ID for each lower sensor end node included in the sensing signal of the infrastructure node stored in the DB and the specific number corresponding to the specific code and causes the gateway to dial the identified specific number Arcs.

For example, if the identification ID of the lower-level sensor end node is an ID assigned to a door sensor, a call is made to a specific number, for example, 123-0001 corresponding to a code set in the door sensor, e.g., 01, It is recognized that an event related to a door has occurred in the house where the door is located. That is, the specific number refers to a number corresponding to each event among the reception numbers assigned to the service server, and the service server has three reception numbers 123-0001, 123-0002 and 123-0003, Assuming that 123-0001 corresponds to the door detection sensor, 123-0002 corresponds to the fire detection sensor, and 123-0003 corresponds to the gas detection sensor, if the calling number (CID) of 345-6789 is left in 123-0001 , The service server can confirm that the activity is detected on the door detection sensor on the caller side using 345-6789.

In this case, when a call is simultaneously generated from at least two gateways, a call is sequentially selected according to preset call queuing information, and a control is performed so that the preset call occurrence time is extended to the control server during a waiting time until a call is selected do.

The service server receives a reception number corresponding to the received call including the identification ID and a call originating number of the call from the gateway of the control server and attempts authentication by checking whether the gateway identification ID is registered as a monitoring service member, And transmits the call connection acknowledgment message and the status information of the received gateway to the monitoring service server when the identification ID is valid.

In step 526, the monitoring service server broadcasts the event type reported from the service server to at least two management servers linked through the network. In step 528, the information broadcasted through each of the interlinked management servers And collects the collected results and provides them to the administrator or the protector portable terminal in step 530. [

On the other hand, if it is determined in step 517 that the event is an event generated from the infrastructure node included in the predetermined priority level, the process proceeds to step 526 and is directly routed to the monitoring service server through the gateway to request an emergency call service Performs operations below step 526.
