It's about how.

As aging society grows, the number of the elderly living alone is increasing, and some of the elderly living alone are found by neighbors or relatives within a few months of death, which is becoming a social issue.

Local governments or countries have life managers or social workers (hereinafter referred to as “managers”) who regularly visit and care for the elderly who live alone. In addition, a system for caring for the elderly living alone has been introduced and operated, but it has reached its limit due to lack of budget and time. For example, one manager is responsible for more than 500 senior citizens who live alone and often do not live near the management center. Therefore, it is virtually impossible to visit them all for a short period of time and check their health.

In order to solve the above problems, a system for attaching a part of the body to check the heart rate and body temperature or a system for detecting and checking infrared rays generated from a remote control of a home appliance used by an elderly person has been developed.

Meanwhile, the elderly management system, which is currently commercially available, adopts a method of connecting a sensor to a computer based on a computer. However, they have the following problems.

First, the method of attaching and checking a part of the body is the most reliable method, but since it transmits the body information wirelessly using an independent power source, the battery is used up frequently and needs to be recharged or replaced frequently. It is inconvenient to attach to and work on.

Second, a system that detects and checks infrared rays generated from a remote control of a home appliance is likely to make an error such as judging as an emergency state by leaving the house for a long time or leaving the house for a long time or not using the remote control in a normal state.

Third, there is a problem in that the computer-based method cannot be handled by the elderly who live alone and the cost of providing the computer together if the elderly do not own the computer.

Accordingly, an object of the present invention is to provide a system and method for analyzing the motion detection signal to predict the status of the elderly living alone and to notify the administrator.

In addition, the present invention installs a gateway for detecting and transmitting a motion detection signal in the residential of the elderly living alone, and by analyzing the information transmitted from the gateway in the central server, the status of the elderly living alone without the configuration of a computer in the living alone. It is an object of the present invention to provide a system and method which can be used.

The elderly living alone management system according to the present invention can predict the status of the elderly living alone, without the configuration of a computer in the living alone, elderly people can understand the status of the elderly living alone, and may require emergency relief and treatment. The first priority can be visited to improve the efficiency of managing senior citizens living alone.

In addition, the present invention can grasp the status of a number of elderly people living alone in the central server has the effect that one administrator can manage a larger number of elderly people living alone.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the accompanying drawings, the same names will be described with the same reference numerals.

1 is a block diagram of a senior citizen management system using a motion sensor according to an embodiment of the present invention.

Elderly living management system according to an embodiment of the present invention is composed of a motion sensor 10, the gateway 20, the central server 30 and the mobile communication terminal (40).

The motion detection sensor 10 is connected by wire or wirelessly, and transmits the detected detection signal to the gateway 20 whenever a motion detection signal of a human motion is detected.

The motion detection sensor 10 includes an ultrasonic sensor, an active infrared sensor, an optical sensor, and the like, and may be modified according to those skilled in the art. In addition, the motion detection sensor 10 may be installed for each living space. For example, one or more may be installed in each of a bedroom, a kitchen, a living room, and a bathroom, and a plurality of installations may be provided according to the size of the space. The connection setting of the gateway 20 that receives the detection signal of the motion detection sensor 10 may be selected from wired or wireless according to the distance between the motion detection sensor 10 and the gateway 20 and the living space of the elderly living alone. It can be done as one. For example, if the gateway 20 is installed in the living room, the motion detection sensor 10 installed in the living room may be connected to the gateway 20 by wire, and the motion detection sensor 10 installed in the bathroom may be wireless. Can be connected.

The wireless connection is Zigbee, RF communication, UWB, Bluetooth, IrDA, etc., but Zigbee communication is most preferable because a large amount of data is not transmitted and can be used for a long time with low power.

When the gateway 20 is connected to the motion detection sensor 10 by wire or wirelessly and generates a detection signal, the gateway 20 receives motion information including an installation position and a detection time of the motion detection sensor 10 in which the detection signal is generated for a predetermined time. Accumulate and transmit to the central server 30 periodically.

That is, the installation location of the installed motion detection sensor 10 is stored in the gateway 20 so that when the motion detection signal is received, the location of the detected motion detection sensor 10 can be grasped. For example, the sensing information stored in the gateway 20 is accumulated as <living room, 2008.10.10.09.05.00>.

In addition, the accumulation period may be limited when motion is continuously detected. The accumulation period and the transmission period may change according to the information of the elderly living alone. If the elderly living alone are uncomfortable or have serious diseases, the accumulation cycle and transmission cycle should be short.

The central server 30 analyzes the operation information transmitted from the gateway 20 and notifies the manager of the analyzed analysis information.

As a notification method, an ARS message to a wired telephone, an SMS or a voice message to the mobile communication terminal 40, and the like can be considered. For example, the notification is transmitted to the mobile communication terminal 40 in the form of an SMS message. Such a notification method belongs to a known technique and can be easily implemented by those skilled in the art, and thus a detailed description thereof will be omitted.

2 and 3 show the configuration of the gateway and the central server according to an embodiment of the present invention, respectively.

The configuration of the gateway 20 according to the present invention comprises a wired / wireless receiver 21, a controller 22, a memory 23, and a communication unit 24.

The wired / wireless receiver 21 is connected to the motion detection sensor 10 by wire or wireless to receive a motion detection signal detected by the motion detection sensor 10.

The control unit 22 accumulates the operation information including the position and the detection time of the motion detection sensor 10 corresponding to the motion detection signal received by the wired / wireless receiver 21 in the memory unit 23 for a predetermined time. .

 The communication unit 24 is connected to the PSTN or the Internet and periodically transmits operation information accumulated by the control signal of the control unit 22 to the central server 30.

In the above configuration, the gateway 20 may be configured to transmit the analyzed result to the central server 30 by analyzing the operation information. At this time, the control unit 22 accumulates the operation information including the position and the detection time of the motion detection sensor 10 corresponding to the received motion detection signal in the wired / wireless receiver 21 for a predetermined time, Periodically analyze the accumulated operation information to generate the analysis information, the communication unit 24 transmits the analysis information to the central server 30 in accordance with the control signal of the control unit 22.

The configuration of the central server 30 is simply composed of a communication unit 31, a memory unit 32, a management control unit 33, SMS module 34.

The communication unit 31 receives operation information transmitted from the communication unit 24 of the gateway 20.

The memory unit 32 stores information on the elderly living alone, and the management controller 33 loads the living elderly information corresponding to the operation information and analyzes the received operation information together to generate analysis information. The abnormal state is stored and output. Seniors living alone may include their address, name, age, telephone number, and sleeping time.

The SMS module 34 transmits analysis information to the mobile communication terminal 40 of the manager in accordance with the control signal of the management control 33. The analysis information can be transmitted to all the elderly living alone, or can be sent only to the number of people selected according to the priority.

In the above configuration, if the configuration to transmit the analysis results by analyzing the operation information in the gateway 20 to the central server 30, the central server 30 is sent to the administrator through the SMS module (3) It is simplified to be transmitted.

In this embodiment, the SMS module 34 is configured in the central server 30. However, according to the embodiment, the SMS module 34 is configured outside the central server 30 or connected to a commercial SMS center through the communication unit without the SMS module 34. You may make it possible.

The method of generating the analysis information may be in various forms. If there is no movement of the elderly living alone for a predetermined time interval, there is a method of determining an abnormal state.

On the other hand, when the elderly living alone will not be detected the movement of the elderly living alone. In consideration of such a situation, another embodiment of the present invention further adding a human body sensor will be described.

Information on the sleeping time of the elderly living alone may be input and stored in advance by the administrator. Based on this information, if there is no movement of the elderly living alone in sleep time, it is determined as normal.

On the other hand, even when the elderly living alone, the movement of the elderly living alone is not detected.

4 is a block diagram of a senior citizen management system using a motion sensor and a human body sensor according to an embodiment of the present invention.

4 is further characterized in that the human body sensor 11 is further added in a pair with the motion sensor 10.

The human body sensor 10 includes a heat sensor and an infrared sensor, and among the infrared sensors, a passive infrared sensor is preferable.

In particular, the passive infrared sensor can measure the amount of infrared light. Although the infrared value varies depending on the distance between the human sensor 11 and the elderly living alone, the infrared amount may be determined under the assumption that the elderly living alone do not move, and the description thereof will be described in detail below. On the other hand, the passive infrared sensor may output a result regarding the presence of the human body according to the amount of infrared rays.

In the above configuration, if the motion information of the motion detection is not received from the motion detection sensor 10 within a predetermined time, the state of the elderly living alone is determined through the detection information of the human body sensor 11.

In the above configuration, there may be two embodiments.

First, the normal state and abnormal state of the elderly living alone can be determined in the central server 30, and the second, the normal state and abnormal state of the elderly living alone can be determined in the gateway 20. Therefore, the present invention may be a different embodiment depending on where the subject of the judgment is, and the subject of the judgment should include a memory storing information on the elderly living alone and a process of judgment.

First, we look at the case where the subject of judgment is the gateway.

In this case, the gateway 20 detects a signal of the motion detection sensor 10 to generate and accumulate motion information, and if there is no motion detection signal within a predetermined time, the human body detection sensor 11 for detecting infrared rays emitted by the human body. The sensing result is generated from the central server 30 and transmitted. Sensing results can be infrared radiation or the presence of the human body.

The central server 30 compares and analyzes the information (operation information, sensing result) transmitted from the gateway 20 with the elderly living information and notifies the administrator.

At this time, senior citizens living alone include a photo image, name, resident registration number, address, age, telephone number, illness name, manager, sleep time, and the like.

Consider the second case above.

In this case, the gateway 30 determines the normal state and the abnormal state and transmits the result to the central server 30. The central server 30 notifies the administrator of the status information of the elderly living alone according to the received information.

As mentioned above, an embodiment of measuring the amount of infrared rays in the human body sensor 11 will be described.

The amount of infrared rays detected is different depending on the distance between the human body sensor 11 and the elderly living alone. Therefore, the amount of infrared light detected when the elderly living alone is meaningless. When the elderly living alone do not move, that is, the motion detection signal is not detected by the amount of infrared light measured every certain time can be seen the temperature change of the elderly living alone.

Accordingly, the amount of change in the body temperature is estimated by the infrared value measured in the absence of movement, and if the value of the body temperature gradually decreases, it can be estimated as a sudden death condition, and prescribed as an emergency state to notify the manager. can do.

5 is a flowchart illustrating a gateway according to an embodiment of the present invention, which is a flowchart according to the configuration of FIG. 4.

First, it is determined whether a motion detection signal is received from the motion detection sensor 10 within a predetermined time (S11). As a result of the determination, when the motion detection signal is received within a predetermined time, motion information including the position and the motion time of the motion detection sensor 10 is accumulated (S12).

The accumulated operation information is confirmed by the transmission period (S13), and transmitted to the central server 30 according to the transmission period (S14).

If it is determined in step S11 that the motion detection signal is not received within a predetermined time, the sensing result is generated using the human body sensor 11 for detecting infrared rays emitted by the human body (S15), and the central server ( 30) (S14).

The information transmitted to the central server 30 is compared and determined by the central server 30. FIG. 6 is a flowchart illustrating the determination of the central server according to an embodiment of the present invention, and there is no motion detection signal within a predetermined time. Shows the decision flow of the central server.

6 shows a subsequent determination process when there is no movement of the elderly living alone for a certain time.

First, it is determined whether the human body is detected based on the sensing result of the human body sensor 11 (S21).

If the human body is not detected, the elderly living alone do not exist in the residence, that is, the state predicted to go out and determine the normal state (S22).

When the human body detection signal is detected, the information on the elderly living alone is loaded to check whether it is the normal sleeping time of the elderly living alone (S23).

If it is sleep time, it is determined that the normal life to sleep (S24), if not the sleep time is determined to be an abnormal state and alarms the manager (S26). For example, a text message may be transmitted to the mobile communication terminal 40 of the manager.

In the present embodiment, the above-described determinations are performed by the central server 30, but may be performed by the gateway 20.

Meanwhile, a description will be given of another embodiment in which the status of the elderly living alone is determined by referring to the presence of the elderly living alone in the residence, the movement information of the elderly living alone, such as going out of the residence and returning to the interior of the residence.

In another embodiment of the present invention shown in Figure 7 has the greatest feature in using the RFID reader (12, 13, 25) in addition to the motion sensor (10). The RFID reader 25 is formed integrally with the gateway 20, and the RFID reader 13 and the RFID reader 12 are installed independently of the gateway and are connected to the gateway 20 by wire or wirelessly. The RFID reader 12 is shown to be installed together with the motion detection sensor 10, the RFID reader 13 is shown to be installed separately. Installation positions of the RFID readers 12, 13, and 25 may vary. It may be installed in each space of the residence, or may be installed in each space and entrance of the residence, or may be installed only at the entrance door. Even when installed at the door, it may be installed at only one side of the door, or may be installed at both sides of the door. In any case, it is sufficient to be installed so as to know the existence of the elderly living alone with RFID tags or moving information.

The RFID readers 12, 13, and 25 read RFID tag information from an RFID tag (not shown). The RFID tag may be active or passive, and the RFID tag may be a card type, a necklace type, a ring type, a dongle type, etc., which can be carried by the elderly living alone. The RFID tag information is information stored in the RFID tag, and may include information for identifying the elderly living alone, or may include identification information given to each residence, or include identification information provided for each gateway. You may. It is only necessary to identify the existence of the elderly living alone or to the extent necessary to extract mobile information. The use of the identification information provided for each residence or the identification information provided for each gateway starts from the assumption that one person living alone lives in the residence or gateway. In addition, the RFID tag may further include various types of information. For example, various types of information may be additionally stored, such as information required to perform a transportation card function and information required for an elderly person to use social security facilities.

The wire / wireless receiver of the gateway 20 receives the motion detection signal from the motion sensor 10 by wire or wirelessly, and receives the RFID tag information from the RFID readers 12 and 13 that receive the RFID tag information from the RFID tag. Receive by wire or wireless. The controller 22 controls to generate motion information from the motion detection signal received by the wired / wireless receiver 21 and store the motion information in the memory 23. The motion information is information on the movement of the soloist, which may be information on the location information and the detection time of the motion detection sensor 50 which sent the motion detection signal. The controller 22 generates RFID tag detection information based on the RFID tag information received from the wire / wireless receiver 21 and controls the RFID tag detection information to be stored in the memory unit 23. The RFID tag detection information includes at least one of the information of the RFID reader which has sent the RFID tag information, the installation position of the RFID reader, the time at which the RFID tag information is received, and the RFID tag information.

The gateway 20 may store the motion detection signal and the RFID tag detection information for a predetermined period of time and then transmit it. If an urgent report is required according to the judgment of the gateway 20 or the instruction of the central server 30, the gateway 20 It may be to be sent directly to the central server 30 without storing in the unit (23).

The communication unit 24 transmits the information including the operation information and the RFID tag detection information stored according to the control signal of the control unit 22 via the PSTN or the Internet to the central server 30.

The central server 30 may analyze the status of the elderly living alone using the operation information and the RFID tag detection information.

8 is a flowchart illustrating a specific method of analyzing the status of the elderly living alone according to the presence of the elderly living alone and the movement of the elderly living alone according to an embodiment of the present invention.

First, the gateway 20 or the server 30 receives or receives the operation information of the elderly living alone and the RFID tag detection information. Based on the operation information of the elderly living alone and the RFID tag detection information, it is determined whether the elderly living alone and whether the elderly living alone.

In order to analyze the status of the elderly living alone, it is determined whether there are movements of the elderly living alone and whether the elderly living alone are in the residence, and the analysis is performed to estimate the status of the elderly living alone. In FIG. 8, first, it is determined whether there is a movement of the elderly living alone for example (S31), and then it is determined whether the elderly living alone are living (S32, S33). However, it is also possible to change the order to first determine whether the elderly living alone are in the place of residence, and then determine whether there are movements of the elderly living alone.

It is determined whether there are movements of the elderly living alone (S31). If there are movements of the elderly living alone, it is determined whether the elderly living alone are living (S32), and the elderly living alone are determined to be in a normal state. (S34). If there is a movement of the elderly living alone, but the elderly living alone is not in the residence, it is determined as an error, outsider visit / invasion or RFID tag (S35). If the elderly living alone are living alone, the elderly should live in their homes, but the system may have the above-mentioned results if an outsider visits or invades without the elderly living alone, or if the elderly living alone lose their RFID tags. Can be. If there is no movement of the elderly living alone, it is determined whether the elderly living alone is in the place of residence (S33), and if it is in the residence, it is determined whether it is sleeping time again (S38). As a result of the determination in step S38, it is determined that the sleep time is normal (S39), and when it is not the sleep time, it is determined abnormal (S36).

Determining whether there is a movement of the elderly living alone is determined based on the motion detection signal and motion information from the motion detection sensor 10.

The determining of whether the elderly living alone is in the residence (S32 and S33) is based on the RFID tag information and the RFID tag detection information.

As one embodiment, an RFID reader can be provided in the passage of entry and exit. Two or more RFID readers are installed in the passageway, and if the reader detects the RFID tag in order from the inside reader, it is determined that the RFID reader has moved out of the residence through the access passage. When the RFID tag is detected in the order of the inner reader, it may be determined that the RFID tag is moved into the residence through the access passage.

In another embodiment, an RFID reader capable of opening a door is installed outside and inside the door, and if an RFID reader on the outside of the door is used, the RFID reader inside the door is determined to enter the residence. In such cases, it may be determined that the person has left the residence.

As another embodiment, an RFID reader can be provided so as to cover the entire space of the residence. An RFID reader may be installed in each room, or as long as the communication distance between the RFID reader and the RFID tag is long. Since the RFID tag can transmit RFID tag information, it is easy to identify the RFID tag owned by the elderly living alone.

In the present invention, the administrator may help to manage priorities and manage a large number of the elderly living alone through information transmitted to the mobile terminal for managing the elderly living alone.

 The present invention can be modified in various ways. For example, when a long outing is required, the gateway 20 is provided with an outing button to notify the central server 30 of the outing, and during the outing time, the operation of the motion sensor 10 and the human body sensor 11 is performed. By stopping the power consumption can be reduced, and equipped with an emergency button can be carried out with a configuration that notifies the central server of the immediate elderly living alone.

When the central server 30 is determined to be in an abnormal state or a signal of an abnormal state is received, the residential map as well as the information of the elderly living alone are simultaneously displayed on the screen, and the output screen is transmitted to the mobile communication terminal 40 of the administrator. This can increase the efficiency of managers visiting the elderly living alone.

Therefore, it will be understood that the present invention can be implemented by those skilled in the art in a modified form within the scope of the claims of the present invention and the specific contents for the practice of the present invention.
