The short distance communication means 210 transmits the short distance wireless communication with the short distance communication means 210 of the gateway apparatus 200, ) Is capable of short-range communication. That is, when the emergency call device 300 that the user is always carrying moves out of the coverage area C on the moving route of the user, the communication with the gateway device 200 is disconnected.

Through the emergency call device 300, it is possible to determine whether a user exists in the coverage area C according to the state of short-range communication with the gateway device 200. [ That is, if the emergency calling apparatus 300 and the gateway apparatus 200 are capable of short-range communication, the user is determined to be located within the coverage area C, and if the communication is impossible, (300 '). To this end, the coverage area C capable of short-distance communication by the short distance communication means 210 of the inter-gateway device 200 is set to have a range approximate to the residence area in the home.

The management center 500 is a group for protecting users residing in a place where the gateway device 200 is installed from an emergency situation and receives sensing information from each gateway device 200 and grasps whether the user is in an emergency state in real time And management. That is, when the management center 500 receives the sensing information related to the fire occurrence from the specific gateway apparatus 200, the management center 500 dispatches 119 fire departments and rescue sources to the place where the gateway apparatus 200 is installed, The user can automatically make a call connection with the mobile terminal 200 to ascertain the urgency of the specific user.

The management center 500 analyzes the activity amount information among the sensing information received from the gateway device 200. When the activity amount information does not change or only a minute amount of activity is detected for a set time period (for example, one day) It can be determined that an abnormal state has occurred to the user and the call can be connected to the gateway device 200 to accurately ascertain the cause and dispatch a life manager to a place where the gateway device 200 is installed. In the management center 500, one or more servers for communicating with the gateway apparatus 200 are constructed.

In addition, the management center 500 receives information on whether the user is going out or returning through the gateway device 200 installed in the home, and provides a service corresponding to each state according to the outgoing or returning state of the user. In the outgoing mode, which is the user's outing state, an emergency situation monitoring service is provided through the gas or fire detection sensors 110 and 120, and a crime prevention service is provided through the activity detection sensor 130-N. Also, in the return mode, which is the return state of the user, it also provides an emergency situation monitoring service through the gas or fire detection sensors 110 and 120, and further provides a user monitoring service for monitoring the user and a health care service for managing the user's health status do.

As described above, the determination of the outgoing or returning state of the user is performed intelligently through the gateway device 200, the emergency call device 300 carried by the user at all times and the sensors 130-N provided in the home, Switches the service mode automatically provided according to the user's status.

The gateway device 200 is a gateway between a plurality of sensors 110, 120, and 130-N and an external management center 500.

The short range communication unit 210 is a means for performing short range communication such as Bluetooth, Zigbee and WiFi. The short range communication unit 210 includes various sensors 110, 120, and 130-N installed in the home 100, And performs near-field communication with the device 300. The short-range communication unit 210 has a communication coverage having a predetermined radius or a predetermined range of ranges at the installed point. Short-range communication is possible within the communication coverage, and communication outside the coverage is impossible.

The remote communication unit 220 includes a communication modem such as an LTE modem, a CDMA modem, or a WCDMA modem, and communicates with the management center 500 at a remote location via the communication network 600. Alternatively, communication with the management center 500 may be performed via the Internet, PSTN network, or the like via the LAN card, the PSTN modem, or the like.

The speaker 230 as the call output means amplifies the voice received from the management center 500 so that the user can easily listen to the voice when the voice communication is established with the management center 500 through the remote communication unit 220. The microphone 240, which is a call input unit, receives the user's voice data and transmits the voice data to the management center 500 through the remote communication unit 220.

The display unit 250 includes an LED for indicating the operation state of the gateway device 200 and a liquid crystal display means for displaying the process information.

The storage unit 270 stores sensing information of the various sensors 110, 120, and 130-N and the emergency call device 300 collected by the gateway device 200. In addition, the storage unit 270 stores the telephone number information of the management center 500 and the emergency situation room, and is stored corresponding to each shortcut button of the input unit 260. In addition, a guidance message transmitted when providing various services or when a call is interrupted is stored.

The control unit 280 controls the overall operation of the gateway device 200. The control unit 280 transmits the collected sensing information to the management center 500 and has a function of connecting a call to an external management center 500 . The control unit 280 controls the plurality of sensors 110, 120, and 130-N provided in the assumption 100 and the sensing information collected from the emergency call device 300 that the user always carries, Stores the communication state in the storage unit 270, and transmits the stored information to the management center 500 at the remote site via the remote communication unit 220. [

In particular, according to the present invention, the control unit 280 of the gateway device 200 determines the outgoing and returning states of the user, performs the intelligent mode switching process according to each state, and provides the service according to the switched mode Role. The detailed configuration of the control unit 280 of the gateway device 200 will be described with reference to the drawings.

3 is a diagram illustrating a configuration of a control unit included in a gateway apparatus of a system in which an intelligent mode switching service providing method using a home gateway apparatus according to an embodiment of the present invention is implemented.

3, the control unit 280 of the gateway device 200 according to the present invention includes a data processing module 282, a mode determination module 284, a mode switching module 286, a service providing module 288, .

As described above, the data processing module 282 collects sensing information and performs general data processing such as communication with the management center 500 and call control processing.

The mode determination module 284 determines the outgoing and returning states of the user through the emergency call device 300 and the sensor 130-N and intelligently determines the current mode based on the determination . The mode determination module 284 confirms the local communication state with the emergency call device 300 that the user is always carrying and confirms the motion detection state information of the activity amount detection sensor 130-N to determine whether the user goes out and return . Here, the state of short-range communication with the emergency calling apparatus 300 is checked at a predetermined time interval. This is because an excessive communication state check increases the load on the system.

First, when the user confirms that the local communication with the emergency calling apparatus 300 carried by the user is disconnected, the user determines that the user is out of the local communication coverage and determines that the user has gone out. That is, when the user carries the emergency call device 300 and leaves the place of residence and goes out, short distance communication between the device 300 and the gateway device 200 becomes impossible, . At this time, first, when the current mode is the return mode.

Next, the user's returning judgment is made when the current mode is the outgoing mode, and when the movement is detected by the activity amount sensor 103-N provided in the assumption 100, the user is judged as returning from the outgoing , It is determined that the user has returned. In addition, it is possible to determine whether or not the user can perform close-range communication with the emergency call device 300 carried by the user along with the motion detection, and to determine that the user has returned to the near-end communication connection. The reason for this determination is that the gateway device 200 does not always check whether the emergency call device 300 is connected to the emergency call device 300 only when it is determined that communication with the emergency call device 300 is possible first, The accuracy of the judgment may deteriorate. Therefore, it is possible to increase the accuracy of the return judgment by judging the return when the motion is detected.

In addition, if the user's return is judged only by the motion detection, there is a possibility that the user is determined to return even when an external intrusion other than the user occurs. Therefore, . That is, when the movement is detected in the outgoing mode without continuously operating the local communication means, it is possible to determine whether or not the user returns via the local communication means, thereby reducing the load of the local communication means.

The mode switching module 286 switches the mode to the corresponding mode according to the mode determination result according to the determination of the user's going out and returning in the mode determination module 284. Accordingly, when determining the outgoing mode, the gateway device 200 sets the current mode to the outgoing mode and transmits the currently switched mode information to the management center 500. [ When the return mode is determined, the current mode is set to the return mode in the gateway device 200, the currently switched mode information is also transmitted to the management center 500, and the management center 500 provides the corresponding service .

The service providing module 288 performs various functions provided in the gateway device 200 and various services through the management center 500 at a remote location. The general emergency condition monitoring service is described as a service provided through various sensors 110, 120, and 130-N in FIG. 1 and FIG. 2, and will not be described here. In addition, since the emergency condition monitoring service is provided regardless of the user's going out and returning, the emergency situation monitoring service is commonly applied to both the outgoing mode and the returning mode of the gateway device 200.

On the other hand, the user monitoring service and the health care service are services provided only when the user is located within the home 100. [ Therefore, only when the mode switching module 286 is set to the return mode, the service is activated and provided. The user surveillance service is a service for monitoring information on an anomaly occurring to a user through a user's movement and an emergency call signal generated from the emergency call device 300. [ The health care service checks health status of the user through a motion sensor and various sensors, and provides a health care service through a management center 500 at a remote place. At this time, it includes a call service to the nurse or physician in charge.

Also, the security service is a service provided only when the user is not located in the home 100. Therefore, only when the mode switching module 286 is set to the outgoing mode, the corresponding service is activated and provided. The crime prevention service is a service for generating or outputting a crime alarm signal when motion is detected through the activity amount detection sensor 130-N, and for transmitting an alarm signal to the crime prevention center 500 and for further crime prevention. That is, when a user moves outside, if a motion other than a user is detected, it is determined that the user is an external intrusion and performs various actions according to the external intrusion. Of course, as in the case of determining the return mode, when it is determined that the user has not returned through the communication connection confirmation with the emergency call device 300 carried by the user, it is determined as an external intrusion.

4 is a diagram illustrating a configuration of an emergency calling apparatus in a system in which a method for providing an intelligent mode switching service using a home gateway apparatus according to an embodiment of the present invention is implemented.

Referring to FIG. 4, the emergency calling apparatus 300 according to the present invention has a size and an outer shape that can be carried by the user at all times, and includes a local communication means and an emergency call signal generating means. The emergency call apparatus 300 includes an emergency call input unit 310, an emergency signal generation unit 320, an emergency signal transmission unit 330, a short range communication unit 340, and the like. First, the emergency call device 300 can be manufactured in the form of, for example, a bracelet or a necklace so that the user can carry it at all times.

The emergency call input unit 310 allows the user to input an emergency call signal through a button input when an emergency occurs. The emergency signal generator 320 generates an emergency signal according to a user's input. The emergency signal transmitting unit 330 transmits the generated emergency signal to the gateway device 200. The short-range communication unit 340 performs short-range communication connection and connection with the gateway device 200, and performs data communication processing through the short-range communication connection and connection.

Accordingly, the emergency call apparatus 300 can transmit an emergency call signal of the user to the gateway apparatus 200 in the home 100, thereby informing the emergency situation. When leaving the home 100, So that the gateway device 200 can determine the outgoing situation.

5 is a flowchart illustrating a method of providing an intelligent mode switching service using a home gateway apparatus according to an embodiment of the present invention.

A method for providing an intelligent mode switching service according to the present invention will be described with reference to the drawings. First, when the mode is set to the return mode in the gateway device 200, it is possible to communicate with the sensors 110, 120, and 130-N provided in the home 100 and the management center 500 through the gateway device 200, Condition monitoring, user monitoring and healthcare service (S1)

In addition to providing the service, the user accesses and connects to the emergency call device 300, which is always carried by the user, through the local communication unit 210, and monitors the communication state with the emergency call device 300 (S2)

During the monitoring of the communication status, the gateway device 200 determines whether the communication connection with the emergency calling device 300 is maintained or the communication connection is released, thereby determining whether the communication is disconnected. As a result of the determination, if the communication connection is maintained and the short distance communication is normally performed, the procedure is continued to connect to the emergency call device and monitor the communication state (S3)

On the other hand, when it is determined that the emergency call apparatus and the short distance communication are disconnected, it is determined that the user carrying the emergency call apparatus 300 always goes out of the local communication coverage in the home 100 (S4)

If it is determined that the user has gone out, the gateway device 200 performs processing for switching the current mode to the outgoing mode. A procedure is performed in which the current mode is set to the outgoing mode to the gateway device 200 and the fact that the outgoing mode is switched to the management center 500 is performed. Accordingly, the presently provided return mode is switched to the outgoing mode (S5)

In the gateway device 200, a procedure for providing an emergency situation monitoring service and a security service provided in the outgoing mode according to switching to the outgoing mode is performed. Emergency situation monitoring service and security service are also provided through the gateway device 200 in cooperation with the sensors 110, 120 and 130-N provided in the home 100 and the management center 500. (S6)

In the gateway device 200, a process for determining whether or not motion is detected from the activity amount detection sensor 130-N during provision of the security service is performed according to the outgoing mode. If no motion is detected, processing for continuously providing an emergency situation monitoring and crime prevention service is performed (S7)

On the other hand, when the motion monitoring signal is received from the sensor, a process is performed in which the user attempts to connect to the emergency call device carried at all times. That is, an attempt is made to establish a short-range communication connection to the emergency calling apparatus 300 through the short-range communication unit 210 of the gateway apparatus 200. (S8)

It is determined whether or not the emergency calling apparatus 300 and the gateway apparatus 200 are connected to each other through the connection attempt. That is, it is determined whether the device 300 is located in the short-range communication coverage C and is connected to the short-range communication connection or if the short-range communication access connection fails because the corresponding device 300 is not located in the short- (S9)

When it is determined that the connection is established as a result of the connection determination, a procedure is performed to determine that the user returns to the home 100. (S10)

When it is determined that the user has returned, the gateway device 200 switches to the return mode according to user return, sets the return mode to the gateway device 200, and then transmits a return mode change to the management center 500 Processing is performed. In addition, in conjunction with the return mode switching, the gateway device proceeds from the procedure of step S1 to provide a service according to the return mode. (S11)

On the other hand, when it is determined that the connection is not established as a result of the connection determination, a process is performed to determine that an intrusion from the outside has occurred. That is, after the user goes out, movement occurs in the home 100, and since the location of the actual user is not confirmed in the home 100, it is determined that someone other than the user has entered the home.

When it is determined that the intruder is intruding, the gateway device generates an alarm signal indicating the intrusion of the intruder and outputs it to the home 100 or notifies the intruder to the management center 500 to inform the intruder of the intruder. )

Through this procedure, it is possible to more intelligently determine whether the user is going out or returning by using the gateway device 200, and also to provide a service corresponding to the outgoing and returning state automatically without any user's operation do.

FIG. 6 is a diagram illustrating a procedure for switching from a return mode to an outgoing mode of each intelligent mode switching service providing method using a home gateway device according to an embodiment of the present invention.

A procedure for switching the mode switching service from the return mode to the outgoing mode according to the present invention will be described with reference to the drawings.

Referring to FIG. 6, since the user is currently in the return mode state located in the home 100, various services in the return mode are provided.

That is, a process of collecting sensing information by transmitting the information sensed by the sensor to the gateway device is performed, and an information transmission procedure for transmitting the collected sensing information to the management center is performed. By collecting the information and transmitting it to the management center, the emergency situation monitoring service, the user monitoring service, and the health care service are provided (S21, S22)

In addition, when an urgent situation occurs to the user himself / herself, a procedure is performed in which an emergency call signal is generated by inputting an emergency call button to the emergency call device that the user always carries (S23)

When the paging signal is generated in the emergency paging device, the emergency paging signal generated in the gateway device is transmitted through the short distance communication. Upon receiving the emergency call signal, the gateway device immediately sends an emergency signal to the management center to inform the management center of the emergency (S24, S25)

A procedure for determining whether or not the user goes out is performed along with providing various services according to the return mode. First, a procedure for confirming the communication connection state with the emergency calling apparatus that the user always carries out is performed (S26) It is assumed that the emergency calling apparatus is located in the home 100 and provides the service and the user is out of the home and the emergency calling apparatus 200 is not located in the home 100. [

During the checking of the communication connection status, the communication connection is released as the emergency calling apparatus moves out of the communication coverage, and a procedure for confirming the communication disconnection status is performed in the gateway apparatus (S27)

Upon confirming the communication disconnection, the gateway apparatus proceeds to the process of switching to the outgoing mode. In other words, a process of setting the return mode set in the gateway device to the outgoing mode and transmitting information informing the fact that the outgoing mode is switched to the management center is performed (S28, S29)

In this way, when the emergency calling apparatus moves out of the local communication coverage area, the gateway apparatus immediately confirms the emergency calling apparatus and performs processing to switch to the outgoing mode. That is, it is possible to accurately grasp whether or not the user is going out, and to automatically provide a service by switching the mode accordingly.

FIG. 7 is a diagram illustrating a procedure for switching from an outgoing mode to a return mode in each method for providing an intelligent mode switching service using a home gateway device according to an embodiment of the present invention.

A procedure for switching the mode switching service from the outgoing mode to the returning mode according to the present invention will be described with reference to the drawings.

Referring to FIG. 7, since the user is currently in the outgoing mode not in the home 100, various services according to the outgoing mode are provided. That is, an emergency situation monitoring service that collects sensing information from a sensor and monitors whether or not an emergency situation exists, provides a security service.

Assume a state in which motion is detected in the sensor in the home 100 in a state where the user is actually going out while providing such a service. According to this assumption, the movement of the home 100 is sensed by a sensor such as an activity sensor 130-N (S41)

The sensor transmits the sensed sensing information to the gateway device (S42)

The gateway device confirms the communication connection status with the emergency call device (S43)

At this time, since the user is actually out of the office, the emergency calling apparatus is also not located in the local communication coverage area. Accordingly, the gateway device confirms that the communication is disconnected as a result of checking the communication connection (S44)

The gateway device confirms that the communication with the emergency paging device has been disconnected although the motion has been detected, determines that an external intruder has occurred in the current home 100, and generates an external intrusion signal (S45).

Along with the generation of an external intrusion signal, an alarm signal is sent to the management center to inform the outside intrusion. Thereafter, a follow-up response procedure is carried out according to a security service procedure against external intrusion (S46)

On the other hand, it is assumed that the actual user returns from the outgoing state and the user enters into the home 100 during service provision according to the outgoing mode. According to this assumption, the motion of the home 100 is also sensed by a sensor such as an activity sensor 130-N (S51)

When motion is detected by the sensor, the sensed sensing information is transmitted to the gateway device (S52)

The gateway device checks the communication connection status with the emergency call device. At this time, since the user carries the emergency call device and returns to the home 100, the communication connection with the device is established (S53)

The gateway device confirms the communication connection as a result of checking the communication status (S54)

Since the gateway device detects the movement and confirms the communication connection with the emergency call device, the gateway device determines that the user has actually returned and does not intrusion but performs the process of switching the mode of the gateway device to the return mode. S55)

At the same time, a procedure for transmitting the return mode information indicating the user's returning state and the return mode switching to the management center is performed (S56)

In this way, when the emergency calling apparatus enters the short-range communication coverage area, the gateway apparatus first detects the movement, and further confirms the communication connection state with the calling apparatus so as to accurately grasp whether it is the intrusion or the user return . Also, when the user returns, the gateway device can automatically switch to the return mode and provide a service corresponding thereto.
