Description

The present invention relates to a monitoring system and a center device.

In recent years, the aging society has progressed, and the number of households living only with the elderly is increasing. If these elderly people have signs of illness but are not noticed by anyone around them, it is possible that they will become severely ill.

Therefore, there is an increasing need to confirm the safety of elderly parents who live apart. For example, in Patent Document 1, a door sensor is attached to the door of an elderly person's house, a water flow sensor is attached to a toilet, a human body detection sensor is attached to the ceiling of a washroom, and an outside family or the like is attached to the daily life of the elderly. I am trying to confirm the behavior.

Japanese Unexamined Patent Publication No. 2000-12273

However, in the above-mentioned Patent Document 1, it can only be confirmed whether or not a certain level of living activity is achieved. For example, it is only possible to confirm from the status of the door sensor whether or not you are out, from the water flow sensor whether or not you are using the toilet, and from the human body detection sensor whether or not you are using the washroom. , It is not possible to grasp that the level of living activity is gradually decreasing, and changes in health status cannot be detected.

The present invention has been made in view of such problems, and an object of the present invention is to provide a monitoring system and a center device capable of detecting changes in a user's health condition.

According to one aspect of the present invention, a plurality of types of sensors installed in a monitoring target and outputting a detection signal when each detects a predetermined phenomenon, and an abnormal signal installed in the monitoring target and corresponding to the detection signal are transmitted. A monitoring system including a monitoring device for transmitting and a center device installed in a monitoring center for receiving the abnormal signal, wherein the center device is a detection output from a specific sensor among the plurality of types of sensors. A monitoring system is provided that has an analysis unit that analyzes the frequency of occurrence of the abnormal signal derived from the signal and makes a first determination regarding a change in the health condition of the user to be monitored.
By analyzing the frequency of occurrence of abnormal signals, changes in the user's health condition can be detected.

When the increasing tendency of the abnormal signal derived from the detection signal output from the specific sensor satisfies a predetermined condition, the analysis unit may determine that the health state of the user to be monitored has changed.

The center device has an alarm type setting unit for setting whether the abnormal signal is an actual alarm or a false alarm, and the analysis unit is the abnormal signal derived from a detection signal output from the specific sensor. Of these, the first determination may be made by analyzing the frequency of occurrence of the abnormal signal set as a false alarm.

The plurality of types of sensors include a first sensor that outputs the detection signal after a lapse of the first time after the first phenomenon occurs, and the first sensor after the first phenomenon occurs from a second phenomenon different from the first phenomenon. The specific sensor may be the second sensor, including a second sensor that outputs the detection signal after a second time longer than the time has elapsed.
The specific sensor may be a fire detection sensor.

The monitoring device can be set to any of a plurality of modes including a home security mode for manned use, and a security mode signal indicating the set mode is transmitted to the center device to set the home security mode. If this is the case, only when a sensor designated in advance among the plurality of types of sensors outputs a detection signal, the abnormal signal corresponding to the detection signal is transmitted to the center device, and the analysis unit receives the detection signal. Based on the security mode signal, when the home security mode is set, the frequency of occurrence of the abnormal signal derived from the detection signal output from the sensor other than the specific sensor is analyzed, and the monitoring target is monitored. A second determination different from the first determination may be made regarding the change in the health condition of the user.

The analysis unit may make the first determination in consideration of the attribute information of the user to be monitored. The attribute information may include the age and / or family structure of the user.

Further, according to another aspect of the present invention, a center that receives an abnormality signal corresponding to the detection signal from a plurality of types of sensors installed in a monitoring target, which outputs a detection signal when each detects a predetermined phenomenon. The device is a first determination regarding a change in the health condition of the user to be monitored by analyzing the frequency of occurrence of the abnormal signal derived from the detection signal output from the specific sensor among the plurality of types of sensors. A center device having an analysis unit is provided.
By analyzing the frequency of occurrence of abnormal signals, changes in the user's health condition can be detected.

Among the abnormal signals received from multiple types of sensors installed in the monitoring target, changes in the user's health condition can be detected by analyzing the frequency of false alarms generated by the user over a long period of time.

FIG. 6 is a diagram schematically showing an example of the number of occurrences of an abnormal signal set as a false alarm (FIG. 6 (a)) and the rate of increase thereof (FIG. 6 (b)).

Hereinafter, embodiments according to the present invention will be specifically described with reference to the drawings.

FIG. 1 is a schematic diagram showing a schematic configuration of a security system. As shown in the figure, one or more monitoring targets 100 and the monitoring center 200 are connected via a network. The monitoring target 100 may be any living area such as a dwelling unit, a store, or a business establishment. The monitoring center 200 is a facility operated by a security company or the like, and an observer constantly monitors the presence or absence of an abnormality in the monitored object 100. The security system includes a plurality of types of sensors 11 and monitoring devices 12 installed in each monitoring target 100, and a center device 21 installed in the monitoring center 200.

FIG. 2 is a block diagram showing a schematic configuration example of the sensor 11 and the monitoring device 12 installed in the monitoring target 100.

When the sensor 11 detects a predetermined phenomenon, it outputs a detection signal or an emergency signal to the monitoring device 12. The sensors 11 include disaster prevention sensors 111 such as fire detection sensor 1111 and gas detection sensor 1112, security sensors 112 such as human body detection sensor 1121, open / close detection sensor 1122 and destruction detection sensor 1123, and emergency button 1131 and emergency terminal 1132. It may include an emergency notification device 113 and the like.

The fire detection sensor 1111 in the disaster prevention sensor 111 is installed in the monitoring target 100 and outputs a detection signal when a predetermined amount of heat is detected within a certain period of time, or a detection signal when a predetermined amount of smoke is detected within a certain period of time. Is output. The gas detection sensor 1112 is installed in the monitoring target 100, and outputs a detection signal when a predetermined amount of gas is detected within a certain period of time.

In order to suppress erroneous detection, such a disaster prevention sensor 111 outputs a detection signal after a relatively long time has elapsed from the time when a predetermined phenomenon (for example, generation of heat, smoke, or gas) is detected. For example, the fire detection sensor 1111 outputs a detection signal when smoke or heat is continuously detected for 30 seconds or longer. In this sense, the disaster prevention sensor 111 can be said to be a sensor that is difficult to issue a report.

The human body detection sensor 1121 in the crime prevention sensor 112 is installed in or around the monitoring target 100, and outputs a detection signal when the human body is detected within a predetermined monitoring range. The open / close detection sensor 1122 is installed in a window, a door, or the like, and outputs a detection signal when these open / close detections are detected. The destruction detection sensor 1123 is installed on a window or wall of the monitoring target 100, and outputs a detection signal when such destruction is detected.

Such a security sensor 112 outputs a detection signal immediately after detecting a predetermined phenomenon (for example, intrusion of a person, opening / closing or breaking of a window, etc.) (or after a relatively short period of time has elapsed). In this sense, the security sensor 112 can be said to be a sensor that easily issues an alarm.

The detection signal from the disaster prevention sensor 111 or the crime prevention sensor 112 includes information (sensor ID) indicating which of the sensors 11 is derived from.

The emergency button 1131 in the emergency notification device 113 is installed on a wall or the like in the monitoring target 100, and outputs an emergency signal when an operation by the user (for example, pressing a button) is detected. The emergency terminal 1132 is carried by the user, and outputs an emergency signal when an operation (for example, long press) by the user is detected. Such an emergency notification device 113 is a sensor that requires an active operation by the user.

The emergency signal from the emergency notification device 113 includes information (user ID) indicating which user's emergency button 1131 or emergency terminal 1132 is derived from, in addition to the sensor ID.

The monitoring device 12 is used in so-called home security, and includes a time measuring unit 121, a sensor interface 122, an operation unit 123, a display unit 124, a control unit 125, a storage unit 126, a communication unit 127, and the like. The monitoring device 12 may be composed of a plurality of devices, and each component may be distributed and installed in the monitoring target 100.

The timekeeping unit 121 clocks the current date and time and the day of the week, and generates time information.
The sensor interface 122 connects each sensor 11 and the control unit 125 by wire or wirelessly, receives a detection signal or an emergency signal from each sensor 11, and notifies the control unit 125. When the sensor interface 122 receives the detection signal or the emergency signal, the sensor interface 122 stores the detection signal or the emergency signal in the detection information table in the storage unit 126 in association with the reception date and time and the sensor ID (in the case of the emergency signal, the user ID).

The operation unit 123 is a touch panel or the like, and receives operations from the user. The display unit 124 is a liquid crystal display or the like, and an operation screen or the like on the monitoring device 12 is displayed.

As an example, the operation unit 123 may be composed of a liquid crystal touch panel display in which the display unit 124 is integrally configured, and an IC card reader. When the IC card reader reads the user's IC card, the collation information stored in the storage unit 126 in advance is collated, and if authenticated, the user is allowed to operate on the liquid crystal touch panel display. Operation symbols for performing various inputs are displayed on the liquid crystal touch panel display, and when the user selects the symbols, signals are input to the control unit 125.

Further, the operation unit 123 may include a cancel button. Depending on the type of sensor 11, if the user mistakenly outputs a detection signal or an emergency signal, the user can press the cancel button within a predetermined time. In this case, the abnormality signal (described later) corresponding to the detection signal or the emergency signal is not transmitted to the monitoring center 200.

The control unit 125 is composed of a microcomputer including a processor, a ROM (Read Only Memory), a RAM (Random Access Memory), and peripheral circuits thereof, and controls the entire monitoring device 12. Further, when the processor in the control unit 125 executes a predetermined program, the mode setting unit 1251, the abnormality determination unit 1252, and the cancellation processing unit 1253 are realized.

The mode setting unit 1251 sets the security mode based on the user's operation on the operation unit 123, and stores it in the storage unit 126. Further, the mode setting unit 1251 transmits a security mode signal indicating the set security mode from the communication unit 127 to the center device 21. In the present embodiment, it is assumed that the security mode can be set to any of the following "security release mode", "security set mode", and "home security mode".

Security release mode: The monitoring target 100 is set when manned, and intrusion monitoring is not performed.
Security set mode: The monitoring target 100 is set when there is no person, and intrusion monitoring is performed.
Home security mode: The monitoring target 100 is set when manned, and intrusion monitoring is performed by some sensors 11.

As a setting example of each security mode, the user sets the security set mode when going out from the monitoring target 100, sets the security release mode when people frequently come and go such as during the day, and stays at home such as at night. When it is necessary to guard the surroundings of the monitoring target 100, set the home security mode.

Upon receiving the detection signal, the abnormality determination unit 1252 determines whether or not an abnormality has occurred by referring to the security mode stored in the storage unit 126.

FIG. 3 is a diagram for explaining the relationship between the detection signal and the security mode.
When the detection signal from the disaster prevention sensor 111 such as the fire detection sensor 1111 or the gas detection sensor 1112 or the destruction detection sensor 1123 is received, the abnormality determination unit 1252 determines that an abnormality has occurred in the monitoring target 100 regardless of the security mode. The sensor 11 that is determined to have an abnormality regardless of the security mode is designated in advance.

When the security release mode is set, even if the detection signals from the human body detection sensor 1121 and the open / close detection sensor 1122 are received, the abnormality determination unit 1252 determines that no abnormality has occurred in the monitoring target 100. This is because the security release mode assumes that the monitored object 100 is manned. The sensor 11 that is determined to have an abnormality when the security release mode is set is also specified in advance.

When the security set mode is set, when the detection signal is received from any of the sensors 11, the abnormality determination unit 1252 determines that an abnormality has occurred in the monitoring target 100. This is because the security set mode is based on the premise that the monitoring target 100 is unmanned.

When the home security mode is set, when a detection signal from an outer peripheral monitoring sensor (for example, open / close detection sensor 1122) that detects intrusion from outside the monitoring target 100 (outside the dwelling unit) is received, the abnormality determination unit 1252 monitors. It is determined that an abnormality has occurred in the target 100. On the other hand, even if the detection signal from the human body detection sensor 1121 that monitors the presence or absence of the human body in the monitoring target 100 is received, the abnormality determination unit 1252 determines that no abnormality has occurred in the monitoring target 100.

As described above, when the security set mode is set, when any of the sensors 11 outputs a detection signal, an abnormality signal is transmitted to the center device 21. On the other hand, when the security release mode or the home security mode is set, the abnormality signal is transmitted to the center device 21 only when the sensor 11 designated in advance outputs the detection signal. In this sense, it can be said that the security mode determines which sensor 11 outputs the detection signal when the abnormality signal is transmitted to the center device 21.

Returning to FIG. 2, when it is determined that an abnormality has occurred, the abnormality determination unit 1252 stores the abnormality content in the current state information of the storage unit 126, and sends an abnormality signal from the communication unit 127 to the center device 21 of the monitoring center 200. Send. The abnormality signal may include information indicating the detection date and time, information indicating which sensor 11 is the source of the detection signal, information indicating the security mode, and the like. Further, when it is determined that the abnormality has been resolved by the user setting the security release mode or the like, the abnormality determination unit 1252 normalizes the current state information of the storage unit 126 and sends a recovery signal from the communication unit 127 to the center device. Send to 21.

When the abnormality determination unit 1252 receives the emergency signal, the abnormality determination unit 1252 transmits the abnormality signal to the center device 21 regardless of the security mode. The abnormal signal based on this emergency signal may include a user ID in addition to the information included in the abnormal signal based on the detection signal. The emergency signal from the emergency button 1131 or the emergency terminal 1132 may be directly transmitted to the center device 21 as an abnormal signal without going through the monitoring device 12.

When the cancel button on the operation unit 123 is pressed within a predetermined time from the output of the detection signal (or emergency signal), the cancel processing unit 1253 outputs the detection signal (or emergency signal) and cancels the operation. Is stored in the storage unit 126 as a sensor detection log in association with. In this case, the abnormality signal is not transmitted to the center device 21, but the cancellation processing unit 1253 sends a cancellation information signal indicating the sensor detection log from the communication unit 127 to the center every predetermined cycle (for example, once a day). It may be transmitted to the device 21.

The storage unit 126 is composed of a ROM, a RAM, an HDD (Hard Disk Drive), and the like. The storage unit 126 stores the property ID that identifies the monitoring target 100, various programs, and various information for operating the monitoring device 12. More specifically, the above-mentioned detection information table, security mode information indicating the set security mode, sensor detection log, verification information indicating the IC card information of the user who can use the monitoring device 12, and each sensor 11 are specified. The storage unit 126 stores the sensor arrangement information table in which the sensor ID, the sensor type, and the installation position are associated with each other, and the open / closed state of the window or door based on the detection signal from the open / close detection sensor 1122.

The communication unit 127 constructs a communication network such as a VPN (Virtual Private Network) tunnel between the monitoring device 12 in the monitoring target 100 and the center device 21 in the monitoring center 200, and between the monitoring device 12 and the center device 21. Perform encrypted communication with. When transmitting various signals such as the above-mentioned abnormal signal, security mode signal, and cancellation information signal to the center device 21, the communication unit 127 refers to the storage unit 126, assigns a property ID, and then transmits the signal.

FIG. 4 is a block diagram showing a schematic configuration example of the center device 21 installed in the monitoring center 200. The monitoring center 200 is composed of one or a plurality of computers, and includes a communication unit 211, an operation unit 212, a display unit 213, a control unit 214, a storage unit 215, and the like.

The communication unit 211 constructs a communication network such as a VPN tunnel between the monitoring device 12 in the monitoring target 100 and the center device 21 in the monitoring center 200, and encrypts communication between the monitoring device 12 and the center device 21. I do. Then, the communication unit 211 receives the above-mentioned various information and various signals from the monitoring device 12 of the monitoring target 100. In addition, the communication unit 211 periodically performs a healthy check for confirming the communication status with the monitoring device 12 installed in each monitoring target 100.

The operation unit 212 is a touch panel, a mouse, a keyboard, or the like, and receives operations from an observer. The display unit 213 is a liquid crystal display or the like, and a necessary screen is displayed. Then, when the abnormality signal is received from the monitoring device 12 installed in the monitoring target 100, the information of the monitoring target 100 to be dealt with is displayed on the display unit 213 based on the property ID and the sensor ID included in the abnormality signal. Will be done. While looking at this information, the observer can take necessary measures.

The control unit 214 is composed of a microcomputer including a processor, a ROM, a RAM, and the like and peripheral circuits thereof, and controls the entire center device 21. Further, the alarm type setting unit 2141 and the analysis unit 2142 are realized by the processor in the control unit 214 executing a predetermined program.

The alarm type setting unit 2141 sets the type of an abnormality signal from the monitoring device 12 as an actual alarm or a false alarm, and stores it in the storage unit 215 as an alarm information table. The actual alarm is the case where a fire actually occurs and the guard or fire department responds, the case where there is an intruder and the guard or police responds, or the user is suddenly ill and the guard or emergency responds. And so on. A false alarm is a case where an abnormal signal based on a detection signal from the fire detection sensor 1111 is received even though a fire has not actually occurred, and a human body detection sensor even though there is actually no intruder. There are cases where an abnormal signal based on the detection signal from 1121 is received, and cases where the user receives an abnormal signal based on the emergency signal from the emergency notification device 113 even though the user is not actually ill. More specifically, false alarms include when the food is filled with smoke during cooking, or when a user with unstable health, for example, brings a lighter close to a fire sensor and intentionally generates an abnormal signal. including.

The determination and setting of whether it is an actual alarm or a false alarm may be automatically performed by the alarm type setting unit 2141 or may be performed based on an operation by an observer on the operation unit 212. In the latter case, the observer performs a reverse check on the monitored object 100 by telephone or the like based on the property ID and the user ID attached to the abnormality signal, confirms the presence or absence of an abnormality, and the operation unit 212 gives an actual alarm / false alarm. May be entered. If the confirmation cannot be made by telephone, the responder visits the monitoring target 100 to confirm, reports the result to the observer, and the observer gives an actual alarm / false alarm from the operation unit 2 1 2. You may enter it. Further, the actual alarm / false alarm may be discriminated according to the presence or absence of the notification operation to the police or the fire department by the observer. Specifically, for a property that has received an abnormality signal, if an alarm or a report operation to the fire department is recorded, it is determined as an actual alarm, and if an abnormality is detected without a report operation, it is determined as a false alarm. You may do so.

The type of the actual alarm / false alarm set in this way is associated with the abnormality signal, and is further stored in the storage unit 215 by the alarm type setting unit 2141 as an alarm information table with reference to the security mode signal.

FIG. 5 is a diagram showing an example of an alarm information table. As shown in the figure, when (detection date and time), where (property ID), which sensor (sensor ID), in which security mode the detection signal was output, and whether the detection signal was a real alarm or a false alarm. Is stored as a table. The alarm information table may further include a user ID.

Returning to FIG. 4, the analysis unit 2142 analyzes the information from the monitoring device 12 and makes the following determination regarding the change in the health state of the user of the monitoring target 100.

As a first example, the analysis unit 2142 analyzes the alarm information table, and among the abnormal signals, the abnormal signal derived from the detection signal output from the specific sensor 11 (particularly, the abnormal signal set as an erroneous alarm). The frequency of occurrence is analyzed, and it is determined that there is a change in the health condition of the user when a change tendency such as a rapid increase in an abnormal signal from a specific sensor 11 is observed.

In this case, the specific sensor 11 is preferably a sensor 11 that is difficult to issue a report, more specifically, a fire detection sensor 1111 or the like. Anomalous signals from the sensor 11, which is difficult to issue, should not be issued so much, but the fact that such anomalous signals are issued frequently means that the user's cognitive function and other health conditions This is because there is a possibility that some kind of abnormality has occurred in.

For example, if the abnormal signal, which is a false alarm from the fire detection sensor 1111, is rapidly increasing, there is a possibility of smoke or heat generated due to cooking, but in such a case, the generation of smoke or heat is rapidly increased in the monitored target 100. It can be inferred that there is no correction despite the fact that there is no correction. In this case, the sense of smell is weakened and the smoke is not noticed, the person is lethargic and it is troublesome to turn the ventilation fan or open the window, and there is a tendency of mental illness and the fire is intentionally fired. It is suspected that there is a change such as the detection sensor 1111 being alerted.

The rapid increase in the abnormal signal can be determined by whether or not a predetermined condition is satisfied. For example, the analysis unit 2142 may compare the rate of increase of the number of occurrences of abnormal signals for each predetermined period with respect to the reference number of times with a predetermined threshold value. As a more specific example, the predetermined period can be set to one week, the reference number can be set to the number of abnormal signal occurrences in the immediately preceding week, or the average value of the number of abnormal signal occurrences of the same sensor 11 installed in each property. .. Further, the present invention is not limited to the example of determining the degree of increase, and the number of occurrences of such a state may be compared with the threshold value to determine whether or not the frequency is above a certain level.

FIG. 6 is a diagram schematically showing an example of the number of occurrences of an abnormal signal set as a false alarm (FIG. 6 (a)) and the rate of increase thereof (FIG. 6 (b)), and the horizontal axis is time. (Unit is arbitrary) Shows the progress. The solid line is an abnormal signal with a specific property ID0, and the broken line is an abnormal signal with another property ID1.

For example, at time t1, the rate of increase of the abnormal signal of the property ID 0 exceeds the threshold value TH0. Therefore, the analysis unit 2142 determines that an abnormality has occurred in the user of the property ID 0.

The threshold value for the rate of increase may be set in multiple stages, and the analysis unit 2142 may make a determination according to each stage. For example, a two-step threshold (high threshold TH1 and low threshold TH0) is set.

In the example of FIG. 6, for the user of the property ID 1, the increase rate of the abnormal signal exceeds the high threshold value TH1 at the time t2. In this case, since there is a possibility of causing a fire in the immediate vicinity, the analysis unit 2142 determines that the degree of urgency is high. Then, the analysis unit 2142 (or the observer) notifies the registered contact information (a family member living separately, a family doctor, a visiting nurse, etc.) to that effect. When the family members use the same security company, the family member monitoring device 12 may be notified to display the alarm signal history and the predicted symptom.

On the other hand, for the user of the property ID 0, the rate of increase of the abnormal signal at time t1 is between the low threshold TH0 and the high threshold TH1. In this case, the analysis unit 2142 determines that the user has an abnormality, but the urgency is not so high. Then, the analysis unit 2142 (or the observer) can notify the nearest salesperson and recommend a planning change such as the addition of the fire detection sensor 1111. Also, if there is a routine to visit users on a regular basis, change it to a higher priority in the visit list.

The analysis unit 2142 may consider the conditions of the attribute information (age, family structure, etc.) of the user registered in advance. For example, the threshold value may be changed according to the attribute information of the user. That is, based on the family structure registered in advance, when an elderly person lives alone in the monitoring target 100, the threshold value may be set low so that an abnormality may be easily determined. Also, if there is a mental history in the past, the threshold value may be set lower as well. Alternatively, the threshold value may be set high during the daytime and low during the nighttime. This is because they live a normal life during the day, but tend to behave abnormally at night. Further, the analysis unit 2142 may determine that there is a change in the health condition of the user when the abnormal signal is rapidly increasing or decreasing.

In parallel with the above-mentioned determination, the analysis unit 2142 determines an abnormal signal (particularly, an abnormal signal) derived from a detection signal output from a sensor 11 (hereinafter, referred to as a normal sensor 11) different from the specific sensor 11 among the abnormal signals. , False alarm and set abnormal signal) may be analyzed, and it may be determined that there is a change in the health condition of the user when the abnormal signal from the normal sensor 11 is rapidly increasing. That is, the analysis unit 2142 may make a determination different from the determination based on the abnormal signal from the specific sensor 11 based on the abnormal signal from the normal sensor 11.

In this case, the normal sensor 11 is a sensor 11 that is more likely to be triggered than a specific sensor 11, that is, a sensor 11 that is likely to be triggered even in normal life due to the carelessness of the user, specifically, at home. An open / close detection sensor 1122 or the like that outputs a detection signal when the window is opened while the security mode is set is suitable.

Even when the abnormal signal, which is a false alarm from the normal sensor 11, is rapidly increasing, there is a possibility that the health condition of the user is changed. However, as compared with the specific sensor 11, the normal sensor 11 is inadvertently likely to generate an abnormal signal. Therefore, the analysis unit 2142 determines that the degree of urgency is relatively low. Alternatively, the threshold value for determining that there is a change in the health condition of the user may be set higher than the determination based on the abnormal signal based on the detection signal of the fire detection sensor 1111.

Further, when the normal sensor 11 is the above-mentioned open / close detection sensor 1122, an abnormal signal is generated according to the detection signal from the open / close detection sensor 1122 when the home security mode is set, but an abnormal signal is generated when the security release mode is set. Does not occur. Therefore, it is considered that the user can set or change the security mode and can make a normal judgment to some extent. Therefore, when the security mode signal indicates the home security mode, it is appropriate to determine that the degree of urgency is low even if the abnormal signal derived from the detection signal from the open / close detection sensor 1122 suddenly increases.

Further, the analysis unit 2142 may make a determination in consideration of the cancellation information signal. As described above, depending on the type of sensor 11, even if the user mistakenly outputs a detection signal or an emergency signal, if the user presses the cancel button within a predetermined time, the center device 21 will be abnormal. No signal is sent. Instead, the analysis unit 2142 can grasp the cancellation after the sensor detection (sensor detection log) by the cancellation information signal.

In the past, even if a detection signal was output by mistake, the user canceled it properly, but the error signal was transmitted to the center device 21 without being canceled and it was set as a false alarm. , The analysis unit 2142 may determine that there is a change in the health condition of the user. This is because the user is unable to perform the cancellation operation or feels annoyed to cancel, and some kind of care may be required.

In the above example, the change in the user's health condition is determined based on the frequency of occurrence of the abnormal signal set as a false alarm, but the actual alarm and the false alarm should be distinguished. Is not essential, and the determination may be made based on the frequency of occurrence of an abnormal signal including an actual alarm.

This is because the frequency of actual alarms actually occurring is much less than that of false alarms, and it is not important for users with health problems intentionally, but it is identified as actual alarms. This is because there are cases in which an abnormality is generated. Therefore, when making a more accurate judgment, it is preferable to distinguish between the actual alarm and the false alarm, but even if the actual alarm and the false alarm are not distinguished in consideration of simplification of processing of abnormal signal data and the like. Good.

Further, in the analysis of the occurrence frequency of the abnormal signal, the information of the set security mode may be added. That is, the abnormal signal generated when the security mode is the security set mode may be excluded from the analysis target. This is because it is a real alarm or false alarm that occurs when the user is absent, so it is highly likely that it has nothing to do with changes in the user's health condition.

As a second example, the analysis unit 2142 analyzes the alarm information table, and among the abnormal signals, the abnormal signal derived from the emergency signal output from the emergency notification device 113 (particularly, the abnormal signal set as a false alarm). The frequency of occurrence is analyzed, and it is determined that there is a change in the health condition such as the cognitive function of the user when the abnormal signal from the emergency notification device 113 increases rapidly. The emergency signal is not output unless the user intentionally performs a specific operation on the emergency notification device 113. That is, it is unlikely that a signal will be output due to an erroneous operation against the will of the user. As described above, even if an abnormal signal is output by the user's intentional operation, if it is not urgent as a result of confirmation, it is treated as a false alarm.

Many of the emergency signals, which are false alarms, are likely to be caused by intentional operation by a user whose normal judgment is impaired. Such an erroneous operation should be less frequent than, for example, opening a window and outputting a detection signal while setting the home security mode. Nevertheless, the frequent occurrence of emergency signals caused by a specific user means that there are frequent erroneous operations by the user in normal life, and there is a high possibility that there is some change in the user's health condition.

As in the first example, the rapid increase of the abnormal signal in the second example can be determined by whether or not the predetermined condition is satisfied. For example, the analysis unit 2142 may compare the rate of increase of the number of occurrences of abnormal signals for each predetermined period with respect to the reference number of times with a predetermined threshold value. The threshold value for the rate of increase may be set in multiple stages, and the analysis unit 2142 may make a determination according to each stage. For example, a two-step threshold (high threshold and low threshold) is set. In addition, the analysis unit 2142 may consider the conditions of the attribute information (age, family structure, etc.) of the user registered in advance. Further, the determination may be made by comparing the number of occurrences regardless of the degree of increase.

Further, the analysis unit 2142 may change the threshold value based on the security mode signal. For example, when the frequency of setting to the security set mode set when going out is more than a predetermined time (for example, once a day), the threshold value may be set higher to make it difficult to be determined as abnormal. This is because it can be estimated that the more often the person goes out, the more normal the activity is. Also, setting the security mode when going out can be presumed to have normal judgment ability.

As described above, in the present embodiment, since the change in the abnormal signal is analyzed, the change in the health state such as the cognitive function of the user can be detected.
