If the amount of time exceeds the unit period, characterized in that to function as means for causing the process of determining a failure to the outside occurs.

In the present invention, first, after introducing the concept of unit period, the communication terminal apparatus transmits a connection confirmation signal to the server apparatus every unit period, and the server apparatus connects every time it receives a connection confirmation signal. When the response signal is transmitted to the communication terminal device and the server device does not receive the connection confirmation signal, the server device determines whether the connection confirmation signal can be received for each unit period by comparing the time after the reception stops with the unit period. If a failure has occurred, the connection confirmation signal cannot be received. Therefore, the occurrence of the failure can be determined by confirming the reception of the connection confirmation signal. Note that the server device transmits the content according to the reception status of the operation notification signal to the registered watch contact information in addition to the case where the server device transmits voluntarily. The contents to be transmitted include a case in which the server apparatus determines based on the reception status as well as the reception status of the operation notification signal.
In the present invention, when it is determined that a failure has occurred, the fact that the failure has occurred is transmitted to the registered watch contact information, so that the person who watches can understand that the failure has occurred in the system, and the failure has occurred.

That is, in the present invention, during the first detection period based on the unit period, whether or not an operation notification signal output from the user device is received is detected. Since it can be assumed that the device cannot be operated, it is possible to remotely determine that an abnormality has occurred in the watched person.

In the present invention, as another pattern for determining whether an abnormality has occurred in a person to be watched (a user to be watched over) using the unit period, the user equipment is used in the second detection period based on the unit period. Based on the detection result for the presence / absence of reception of the operation notification signal to turn off the power of the person, the occurrence of an abnormality of the watched person is determined. Therefore, in the present invention, if the person being watched keeps turning on the power of the user device during the second detection period, it is assumed that an abnormality that cannot be turned off has occurred in the person being watched. It is judged that it has occurred, and the watched person can respond to care promptly.

In the present invention, if the server device receives the connection confirmation signal in the situation where it is determined that a failure has occurred, it can be determined that the device has recovered from the failure. As a result, the person who watches can get a sense of security at an early stage and the reliability of the system can be enhanced.

In the present invention, the communication terminal device stores the received operation notification signal in association with the date and time, so that the acquired operation notification signal can be secured as log information together with the date and time, and a connection response signal is received. When recovering from the incapable state to the receivable state, log information (operation notification signal and corresponding date and time) during the failure period is sent to the server device, so the server device can monitor the status of the person being monitored during the failure period, Judgment can be made from the transmitted log information.

In the present invention, when the server device receives the operation notification signal as the log information together with the date and time, first, it is determined whether the failure period has exceeded a predetermined detection period based on the unit period, and the predetermined detection is performed. If it is determined that the period exceeds the specified period, the occurrence of an abnormality is determined based on whether or not the received date and time are included in the range corresponding to the predetermined detection period. Based on this, it is possible to know whether an abnormality has occurred in the watched person.

In the present invention, when it is determined that the failure period is longer than the first detection period or the second detection period based on the unit period, the abnormality determination in the first detection period or the second detection period described above and Similarly, since it is determined whether or not an abnormality has occurred, even if it is during the failure period, if the watched person cannot operate the user equipment, such a situation will be recovered after the failure is recovered. This makes it possible to determine that an abnormality has occurred in the person being watched over.
Further, in the present invention, since it is also determined that no abnormality has occurred in the abnormality determination related to the first detection period or the second detection period during the above-described failure period, The situation can be made clearer and the security of the people watching can be enhanced.

In the present invention, the server device transmits time designation information for designating a time related to the unit period to the communication terminal device, and the communication terminal device uses the time designated by the received time designation information as the unit period. Since it is set, the time of the unit period can be controlled appropriately on the server device side. Thereby, it becomes possible to flexibly change in accordance with changes in the lifestyle of the person who can observe the judgment conditions relating to the occurrence of abnormality.

In the present invention, since the server apparatus includes the time designation information in the connection response signal transmitted to the communication terminal apparatus, it is not necessary to transmit the time designation information to the communication terminal apparatus alone. The burden can be reduced and the time of the unit period can be designated according to the break of the unit period, so that the time of the unit period can be changed with good timing.

In the present invention, since it is determined whether or not the connection confirmation signal from the communication terminal device exceeds the unit period and cannot be received by the server device, an abnormality occurs in the case where a failure has occurred and in the person being watched over. Can be determined.
In the present invention, when it is determined that a failure has occurred, the fact that the failure has occurred is transmitted to the registered watch contact, so that the person who watches can smoothly understand that a failure has occurred in the system.

In the present invention, using the detection period (first detection period or second detection period) based on the unit period, it is determined whether an abnormality has occurred in the person being watched over (the user to be watched over). Based on the unit period, the occurrence of abnormality can be determined regularly.
In the present invention, by watching over the fact of failure recovery and transmitting it to the contact address, the anxiety of the watcher due to the occurrence of the failure can be quickly eliminated, and the reliability of the system can be enhanced.

In the present invention, if the communication terminal device is in a state where it cannot receive a connection response signal and then recovers to a state where it can receive a connection response signal, it receives reception log information during the failure period to the server device. Therefore, the server device can determine the situation of the person being watched based on the log information even during the failure period.

In the present invention, the server device can determine whether an abnormality has occurred in the watched person based on the log information even during the failure period.
In the present invention, when it is determined that the failure period is longer than the first detection period or the second detection period based on the unit period, the abnormality determination in the first detection period or the second detection period described above and Similarly, since it is determined whether or not an abnormality has occurred, it is possible to clarify whether or not an abnormality has occurred in the person being watched during the failure period.
In the present invention, since it is also determined that no abnormality has occurred in the abnormality determination related to the first detection period or the second detection period during the above-described failure period, Maintain a sense of security for watching.

In the present invention, the server device transmits time designation information for designating a time related to the unit period to the communication terminal device, and the communication terminal device uses the time designated by the received time designation information as the unit period. Since it is set, the time of the unit period can be appropriately controlled on the server device side, and can be flexibly changed in accordance with changes in the lifestyle of the person who observes the judgment conditions related to the occurrence of abnormality.
In the present invention, since the server device includes the time designation information in the connection response signal transmitted to the communication terminal device, the load of the transmission processing of the server device can be reduced, and the unit period can be adjusted according to the break of the unit period. By specifying the time, the time of the unit period can be changed with good timing.

With regard to “acquisition of operation notification signal”, the watching program P2 is programmed so that the CPU 11 performs control to acquire the operation notification signal output from the television device 5 using the external device connection unit 12. There are various conventional methods for obtaining the operation notification signal. For example, in the monitoring device 10 (CPU 11), the connection destination device of the external device connection unit 12 (the television device 5 in this embodiment). If a user operation is detected, a signal indicating that the operation has been performed (operation notification signal) is sucked up and output from the connection destination device, or the connection destination device itself has a user operation. When an operation notification signal corresponding to the operation is output every time, there is a method of simply acquiring the output operation notification signal with the external device connection unit 12.

For “transmission of the acquired operation notification signal”, the CPU 11 controls the process of creating a copy of the operation notification signal acquired by the external device connection unit 12 and transmitting the copy to the watching server 20 using the communication unit 13. The watching program P2 stipulates. Thereby, the monitoring device 10 watches the acquired operation notification signal and transmits it to the server 20 every time the operation notification signal is acquired.

Regarding the “storage of the acquired operation notification signal”, the watching program P2 defines that the CPU 11 controls the process of storing the other operation notification signal duplicated in the above in the log table 17 of the second memory 16. ing. At this time, the CPU 11 specifies the date and time when the operation notification signal is stored in the second memory 16 by the calendar / date and time function based on the system program P1, and the operation notification signal is associated with the specified date and time in the log table 17. The watching program P2 also regulates the control to store and store. When the operation notification signal is stored, the free space of the second memory 16 is also detected by the CPU 11, and when the free space is not enough to store new log information (operation notification signal and date and time), The watching program P2 also stipulates that the CPU 11 performs control so that new log information can be stored in order from the oldest date and time.

Next, “detecting the connection state with the television device 5”, which is the second main process defined by the watching program P2, will be described. The monitoring device 10 (CPU 11) connects to the television device 5. However, it is determined whether or not a connection error has occurred when it is detected that it has been disconnected by a user other than the power-off operation. If it is determined that a connection error has occurred, it is considered that some error has occurred in the television device 5 (user device), and therefore the CPU 11 performs control for generating a user device error signal and transmitting it from the communication unit 13 to the watching server 20. The watching program P2 defines what to do. Whether or not the connection has been disconnected other than the power-off operation is determined by checking the energization at the terminal related to energization of the external device connection unit 12 or outputting a connection confirmation signal from the external device connection unit 12 and returning a response signal. It will be based on the presence or absence of.

As for the third process “sending a connection confirmation signal to the watching server 20” as the main process defined by the watching program P2, when the installed watching program P2 is activated, an operation confirmation signal is sent from the communication unit 13. The CPU 11 performs control to transmit to the watch server 20, and thereafter, an operation confirmation signal is transmitted at intervals of unit periods included in the watch processing setting information D1 stored in the first memory 15. . According to the regulation of such a monitoring program P2, the monitoring device 10 transmits a connection confirmation signal to the server 20 for each unit period, and determines whether or not a connection response signal transmitted from the monitoring server 20 described later is received. Regardless, a connection confirmation signal is transmitted to the monitoring server 20 for each unit period.

When the operation confirmation signal is transmitted from the communication unit 13 with respect to the fourth “when a failure occurs” which is the main process defined by the monitoring program P2, the communication unit 13 receives a connection response signal corresponding to the operation confirmation signal. The watching program P2 defines that the CPU 11 performs control to determine whether or not. When the connection response signal is received, the watching program P2 also stipulates that the CPU 11 performs control for storing the reception date and time in the 15 reception date and time table D4 in the first memory.

Further, when the communication unit 13 does not receive a connection response signal corresponding to the connection confirmation signal, the CPU 11 determines that a failure has occurred in the system. In this case, it is assumed that either the communication medium including the network NW or the monitoring server 20 corresponds to the failure occurrence location. The communication medium includes various devices that mediate communication such as a wireless LAN router 6 installed in the house H1 shown in FIG. 1 and a server of an Internet service provider (the same applies hereinafter).

Even when it is determined that a failure has occurred, as described above, the monitoring device 10 (CPU 11) transmits a connection confirmation signal to the monitoring server 20 for each unit period, so that a connection response signal corresponding to the transmitted connection confirmation signal is next. It becomes a situation waiting for the time to receive. When the communication response unit 13 receives the connection response signal for the first time in the failure occurrence state, the CPU 11 determines that the failure has been recovered. Then, the CPU 11 determines the occurrence of the failure (when the connection response signal corresponding to the transmitted connection confirmation signal is no longer received), the date and time when the latest connection response signal is received, and the connection response related to the recovery. The reception date and time of the signal is specified from the reception date and time table D4 of the first memory 15, and the operation notification signal associated with the date and time included in the specified date and time range (corresponding to the failure period in the present invention) is stored in the second memory. The watching program P2 defines that the processing specified from the 16 log tables 17 is performed.

Then, the CPU 11 reads the operation notification signal included in the failure period identified above from the log table 17 as the log information during the failure period together with the associated date and time, and transmits the operation notification signal from the communication unit 13 to the watching server 20. The watching program P2 stipulates that In this way, by monitoring the log information during the failure period and transmitting it to the server 20, the monitoring server 20 can determine whether or not an abnormality has occurred in the person M1 to be monitored during the failure period based on the log information. become.

10 and 11 are time charts showing specific examples in the case of the above-described determination of the occurrence of a failure. In these examples, various signals transmitted by the monitoring device 10 are transmitted to the monitoring server when a failure occurs in the communication medium. The signal that cannot be received (cannot be received) 20 is represented (the signal that cannot be received by the monitoring server 20 even if the monitoring device 10 transmits is indicated by a wavy line in FIGS. 10 and 11).

In the time chart shown in FIG. 10, the monitoring device 10 transmits the fourth connection confirmation signal S13, but the connection confirmation signal S13 does not reach the monitoring server 20 due to a failure of the communication medium. Cannot transmit the connection response signal, and as a result, the monitoring device 10 cannot receive the connection response signal corresponding to the transmitted connection confirmation signal S13 by the communication unit 13, and the CPU 11 determines that a failure has occurred at this time. Even when it is determined that a failure has occurred, the monitoring apparatus 10 transmits a connection confirmation signal for each unit period, and receives a connection response signal S25 corresponding to the connection confirmation signal S15 transmitted sixth in FIG. Therefore, at this stage, the CPU 11 determines that the failure has been recovered.

Then, the monitoring device 10 (CPU 11) receives the latest connection response signal S22 when it has not received the connection response signal corresponding to the fourth connection confirmation signal S12 that determines that a failure has occurred. In addition, the reception date and time of the connection response signal S25 for which the recovery is determined is specified from the reception date table D4 of the first memory 15, and the operation notification signal included in the specified date and time period (failure period) is specified from the log table 17. Extracted as log information together with the date and time. It should be noted that the reception date and time of the latest connection response signal from the time when it is determined that a failure has occurred in this way is the beginning of the failure period, since the actual failure occurrence time is not accurately grasped in the present invention, and is transmitted due to the failure. This is because it is included in the log information sent to the server 20 by watching over the operation notification signal that may not have been received. Also in the time chart shown in FIG. 11, the watching device 10 performs the same processing as in FIG.

On the other hand, FIG. 6 shows a main internal configuration of the monitoring server 20 that plays a central role in the monitoring service system 1. A general-purpose server computer is applied to the watching server 20, and various devices are connected to the MPU 21 that performs overall control and various processing by an internal connection line 20a. , Communication module 22, RAM 23, ROM 24, input interface 25, output interface 26, mass storage system (HDD system) 27, and the like.

The communication module 22 is a communication device (communication means) corresponding to a connection module with the network NW and conforms to a required communication standard (for example, a LAN module). The communication module 22 is connected to the network NW via a required communication device (not shown, for example, a router or the like), and the communication device 40 to be used by the monitoring device 10 and the watchers K1 to K3 described above. Communication with 42 etc. is enabled.

The RAM 23 temporarily stores contents and files associated with the processing of the MPU 21, and the ROM 24 stores programs and the like that define the basic processing contents of the MPU 21. The input interface 25 is connected to a keyboard 20b, a mouse, and the like for receiving an operation instruction from the operator of the monitoring service system 1, and transmits the operation instruction received from the operator to the MPU 21. The output interface 26 is connected to the display 20c, and outputs the contents accompanying the processing of the MPU 21 to the display 20c so that the operator can check the current processing contents and the like.

The large-capacity storage system 27 (corresponding to a storage device) stores various programs, databases (DB), various information and the like necessary for providing the watching service. In this embodiment, the server program P10, the watching service program P11, user DB 30, and watch setting information D20 are stored.

The server program P10 defines various processes according to the server operation system, and the MPU 21 performs processes based on the specified contents, whereby the server device 20 fulfills a basic function as a server computer. . The description of the watching service program P11 will be described later, and the user DB 30 and the watching setting information D20 will be described first.

FIG. 7 shows an overview of the user DB 30. The user DB 30 registers a person who uses the watch service as a group of the watched person (user) and the watched person, and identifies a group of the watched person (user). For each user ID, the name of the person to be watched, the device ID / communication address of the user device to be operated by the watched person (becomes a transmission destination for transmitting signals, information, etc. from the watch server 20 to the user device) can be watched. A person's address / phone number / email address, the name / phone number / email address of the person to be watched (corresponding to a pre-registered watch contact address), and the like are stored in association with each other. The monitoring server 20 refers to the user DB 30 so that a necessary notification can be made by e-mail to a person who needs notification. Note that the above-described information in the user DB 30 is submitted by a user (a person to be watched and a person to be watched) who is provided with the watching service in the preparation stage, and the submitted information is registered in the user DB 30 in advance. Thus, the user can enjoy the watching service.

The watch setting information D20 stored in the large-capacity storage system 27 in FIG. 6 includes time information such as the above-described unit period and a detection period based on the unit period. These are set by the operator of the watching server 20 and stored in the large-capacity storage system 27 as watching setting information D20. In the unit period, as described above, the time submitted by the user (the person to be watched and the person to watch) is set, and is referred to by the MPU 21 in the process of determining the occurrence of an abnormality and determining the occurrence of a failure, which will be described later. The The detection period is a reference period for determining whether or not an abnormality has occurred in the watched person, and a time that is a multiple of the unit period is set.

In the present embodiment, two types of detection periods are used in accordance with the types of conditions for determining the occurrence of an abnormality, which will be described later, and a time (2T) that is twice the unit period is set as the first first detection period. The second second detection period is set to a time (4T) that is four times the unit period, and is referred to by the MPU 21 when determining the occurrence of an abnormality, which will be described later. Such setting contents are only an example, and the number of detection periods can be set from a single number to two or more according to the type of determination condition for occurrence of an abnormality. If the time is based on the unit period, it is set to an integral multiple of the unit period or 0.5 times the unit period according to the lifestyle of the user (the person to be watched and the person to be watched), 1 It is also possible to set various multiples such as .5 times.

Next, details of the watching service program P11 will be described. There are three main program contents related to the control processing performed by the MPU 21 defined by the watching service program P2, the first is processing related to transmission of a connection response signal, and the second is processing related to determination of occurrence of abnormality of the person being watched over. Yes, the third is processing relating to the determination of the occurrence of a failure, and the MPU 21 functions as various means (determination means, comparison means, detection means, transmission processing means, etc.) by the MPU 21 performing processing based on these related regulations. To do.

As a process related to the transmission of the first connection response signal, every time the monitoring server 20 receives a connection confirmation signal transmitted from the monitoring device 10 by the communication module 22, the connection response signal is transmitted from the communication module 22 to the monitoring device 10. The watching service program P11 defines that the MPU 21 controls and executes the processing to be performed.

Whether the communication module 22 has received an operation notification signal from the monitoring device 10 during the above-described detection period (first detection period, second detection period), as a process related to the determination of the occurrence of abnormality of the second watched person. The MPU 21 detects whether or not an abnormality has occurred in the watched person M1 (the user to be watched) based on the detection result of whether or not the operation notification signal has been received. The watching service program P11 prescribes.

FIG. 8 is a time chart showing an example based on an abnormality occurrence determination condition (first abnormality determination condition) using the first detection period (twice the unit period). In this time chart, a signal received by the watch server 20 is shown below the arrow line indicating time, a signal transmitted by the watch server 20 is shown above the arrow line showing time, and the unit period is T The connection confirmation signals to be received are represented by S10, S11, and the connection response signals to be transmitted are represented by S20, S21,... (The same applies to other time charts).

In the time chart of FIG. 8, any type of operation notification signal (operation notification signal indicating power-on operation, operation notification signal indicating power-off operation, and other operation notification signals) must be received in the first detection period 2T. If it is detected (when no reception is detected), the MPU 21 of the watching server 20 determines that an abnormality has occurred in the watched person.

That is, as shown in the time chart of FIG. 8, the monitoring server 20 has not received the operation notification signal during the period (2T) from the reception of the connection confirmation signal S13 to the reception of the connection confirmation signal S15. The MPU 21 determines that an abnormality has occurred in the person being watched in accordance with the transmission of the connection response signal S25. Based on this determination, the MPU 21 automatically generates an e-mail indicating that an abnormality has occurred in the person being watched (watch alarm notification; see FIG. 3A), and refers to the user DB 30 in FIG. The generated e-mail is transmitted to the contact (e-mail address) of the watcher associated with the watched person in which the abnormality has occurred, and a process for notifying the watcher of the occurrence of the abnormality is performed. The determination of the occurrence of an abnormality based on the first abnormality determination condition cannot be performed unless the watched person operates the television device 5 at any time corresponding to the first detection period 2T. It is based on the idea that there is a risk that a person who can watch over the condition falls.

FIG. 9 is a time chart showing an example based on a determination condition (second abnormality determination condition) for occurrence of abnormality using the second detection period (four times the unit period). In this time chart, it continues continuously after the unit period (the period from the reception of the connection confirmation signal S10 to the reception of the connection confirmation signal S11 in FIG. 9) in which the operation notification signal indicating that the power-on operation has been received. If an operation notification signal indicating a power-off operation is not received during the second detection period (4T) (when no reception is detected), the MPU 21 of the watching server 20 determines that an abnormality has occurred in the watched person. .

That is, as shown in the time chart of FIG. 9, during the period (4T) from when the connection confirmation signal S11 is received until the connection confirmation signal S15 is received, the monitoring server 20 indicates an operation notification indicating that the power-off operation is indicated. Since no signal has been received, the MPU 21 determines that an abnormality has occurred in the person being watched in accordance with the transmission of the connection response signal S25. When this determination is made, the MPU 21 performs a process of notifying the person who watches over the occurrence of an abnormality, as in the case of the first abnormality determination condition. The determination of the occurrence of the abnormality based on the second abnormality determination condition is performed if the person to be watched does not perform the power-off operation of the television device 5 for a long time as long as the second detection period 4T. However, it is based on the idea that some abnormality may have occurred while watching the television device 5.

Regarding the processing performed by the MPU 21 related to the first abnormality determination condition and the second abnormality determination condition described above, the watching service program P11 has the following prescribed program contents. First, the program contents relating to the first abnormality determination condition will be described. When the monitoring server 20 receives the connection confirmation information, it receives some operation notification signal during the period (one unit period) until the next connection confirmation information is received. The MPU 21 detects whether or not it has been performed, and if it detects that no operation notification signal has been received, the MPU 21 counts one unit period. If it is detected that any operation notification signal has been received, the MPU 21 does not count the unit period. The MPU 21 detects whether or not any notification notification signal has been continuously received for the next unit period (second unit period) of the unit period related to this detection (first unit period), and receives any operation notification signal. If the MPU 21 detects that it has not, the MPU 21 determines that an abnormality has occurred with the reception of the connection confirmation signal at the end of the second unit period (the count number is reset together with the determination of the occurrence of the abnormality).

On the other hand, if it is detected that any operation notification signal is received in the second unit period, the MPU 21 does not count the unit period. In this case, if the counting is performed for the first unit period, the count number is set. Reset. The MPU 21 repeats such processing after the third unit period, and determines whether or not an abnormality has occurred in the watched person based on the first abnormality determination condition.

Describing the program contents relating to the second abnormality determination condition, the MPU 21 determines whether or not an operation notification signal indicating a power-on operation has been received at the first stage. If it does not receive an operation notification signal indicating a power-on operation, it enters a state of waiting for reception, and when it is detected that an operation notification signal indicating a power-on operation has been received, the next following the unit period after receiving the operation notification signal It is determined whether or not an operation notification signal indicating a power-off operation has been received in a unit period (first unit period). If the operation notification signal indicating the power-off operation is received in the first unit period, the process returns to the first stage, and the MPU 21 determines whether or not the operation notification signal indicating the power-on operation is received. If the operation notification signal indicating the power-off operation is not received in the first unit period, the MPU 21 counts one unit period.

When one unit period is counted, the MPU 21 determines whether or not an operation notification signal indicating a power-off operation has been received for the second unit period following the first unit period. Reset and return to the first stage. If the operation notification signal indicating the power-off operation is not received, the MPU 21 further counts one period unit and sets the total count number to two unit periods. When counting two unit periods, the MPU 21 determines whether or not an operation notification signal indicating a power-off operation has been received for the third unit period, and if received, resets the count number to the first stage. If not received, the unit of one period is further counted, and the total count is set to three unit periods.

When the three unit periods are counted, the MPU 21 determines whether or not the operation notification signal indicating the power-off operation has been received for the fourth unit period. If not received, it is determined that an abnormality has occurred with the reception of the connection confirmation signal at the end of the fourth unit period (the count is reset when the abnormality occurs). By repeating such processing, the MPU 21 determines whether an abnormality has occurred in the person being watched based on the second abnormality determination condition.

Next, the contents of the program relating to the determination of the occurrence of the third failure specified by the watching service program P11 will be described. There are two types of content related to the determination of failure occurrence. First, the monitoring server 20 determines that some failure has occurred in the user device (television device 5) when a user device error signal is transmitted from the monitoring device 10. In this case, the MPU 21 determines that a failure has occurred in the user equipment while the communication module 22 is receiving the user equipment error signal, and the user equipment error signal is interrupted. The watching service program P11 defines that it is determined that the equipment failure has been recovered. The MPU 21 automatically generates an e-mail (see FIG. 3C) indicating that a failure has occurred in the system based on the determination of the occurrence of the failure based on such a user device error signal, and registers it in the user DB 30 in FIG. The watching service program P11 also regulates that the generated e-mail is sent to the contact (mail address) of the person watching the group related to the user equipment error signal.

Further, the second judgment regarding the occurrence of the failure defined by the watching service program P11 is based on whether or not a connection confirmation signal is received. Specifically, when the watching server 20 receives the connection confirmation signal through the communication interface 22, the MPU 21 uses its own timer function as a time measuring means to start measuring time after receiving the connection confirmation signal. Keeps on watching until the next connection confirmation signal is received. Then, the MPU 21 compares whether or not the measured time exceeds the unit period, and if it is determined by the comparison that the measured time exceeds the unit period, the MPU 21 determines that a failure has occurred in the system. The watching service program P11 defines.

Based on the determination of the occurrence of the failure, the MPU 21 automatically generates an e-mail indicating that the failure has occurred in the system, and generates the e-mail to the contact information (email address) of all the watchers registered in the user DB 30 in FIG. The watching service program P11 also prescribes that a process of notifying all watchers of the occurrence of a system failure by sending the e-mail (see the failure occurrence notification in FIG. 3D) is performed. In addition, as the occurrence location of the failure in the system determined by the above processing, a communication medium other than the monitoring server 20 (including the network NW, the wireless LAN router 6, the Internet service provider server, etc.), the monitoring device 10, or At least one of the television devices 5 is applicable, and these are external to the watching device 20.

In addition, when the MPU 21 detects that the communication module 22 has received the connection confirmation signal in the situation where the failure has been determined, the MPU 21 determines that the failure has been recovered, and automatically generates an email indicating that the failure has been recovered, The watching service program P11 defines that the generated e-mail (see the failure recovery notification in FIG. 3E) is sent to the contacts (mail addresses) of all watching people.

When the failure is recovered, log information (information in which the operation notification signal during the failure period is associated with the date and time) is transmitted from the monitoring device 10 to the monitoring server 20, so that this log information is received. The watching server 20 determines the situation of the watched person during the failure period. First, the MPU 21 specifies the time from the start of timing related to the determination of the occurrence of failure to the reception of the connection confirmation signal related to determination of failure recovery as a failure period, and this specified failure period is the above-described detection period ( The monitoring service program P11 defines that it is determined whether or not the first detection period or the second detection period is over. As a result of the comparison, if the failure period does not exceed the detection period, the MPU 11 determines that there is no abnormality in the watched person because the abnormality determination period based on the abnormality determination condition cannot be performed. The watching service program P11 defines.

On the other hand, as a result of the comparison, if the failure period is equal to or longer than the detection period, the MPU 11 observes that the determination of the occurrence of abnormality based on the first abnormality determination condition and the second abnormality determination condition is performed using the received log information. The service program P11 is defined. That is, when it is determined that the failure period is equal to or longer than the first detection period, the MPU 11 detects whether the date and time in the received log information is included in the range corresponding to the first detection period, Based on this detection result, when it is detected that it is not included, it is determined that an abnormality has occurred in the person watched during the failure period, and when it is detected that it is included, the person watched during the failure period The monitoring service program P11 defines that it is determined that no abnormality has occurred.

Further, when it is determined that the failure period is equal to or longer than the second detection period, the MPU 11 determines whether or not an operation notification signal indicating a power-off operation is included in a range corresponding to the second detection period. Is specified by the watching service program P11. When it is determined that the operation notification signal indicating the power-off operation is not included, the MPU 11 determines that an abnormality has occurred in the person watched during the failure period, and the operation notification signal indicating the power-off operation is included. When it is determined, the watching service program P11 defines that it is determined that no abnormality has occurred in the person watched during the failure period.

When a determination result based on the first abnormality determination condition and the second abnormality determination condition is obtained, the MPU 11 indicates the determination result (“no abnormality has occurred in the person being watched during the failure period”). Or, an e-mail saying “There was an abnormality in the watched person during the failure period (see FIG. 3 (f))” and the contact information of the watchers K1 to K3 of the watched person M1 ( The watching service program P11 defines that the process of transmitting the generated electronic mail to (mail address) is performed.

10 and 11 are time charts of examples relating to the determination of the occurrence of a failure when a failure occurs in the communication medium as described above, and the program contents relating to the occurrence of the failure of the watching service program P11 described above according to these time charts. Will be described in detail.

In the case of the time chart shown in FIG. 10, the monitoring server 20 can receive the third connection confirmation signal S12. However, even if the unit period is exceeded after the reception, the fourth connection confirmation signal is caused by the failure of the communication medium. Since S13 cannot be received, the occurrence of a failure is determined at the time when the unit period is exceeded in accordance with the contents defined in the monitoring service program P11 described above, and notification of the occurrence of the failure (see FIG. 3D) is performed. Then, the monitoring server 20 continues to fail in the communication medium and cannot receive the fifth connection confirmation signal S14, so that the monitoring server 20 is able to transmit a connection response signal corresponding to the connection confirmation signals S13 and S14. There is no state.

Since the monitoring server 20 can receive the sixth connection confirmation signal S15 in FIG. 10 due to the failure recovery, it transmits a connection response signal S25 corresponding to the connection confirmation signal S15, and at this time, the failure is recovered. It is determined that a failure has been recovered (see FIG. 3E). Since the monitoring device 10 transmits the log information as described above by transmitting the connection response signal S25, the monitoring server 20 receives the log information (information including the operation notification signal together with the date and time). Become.

Since the failure period from the reception of the third connection confirmation signal S12 to the sixth connection confirmation signal S15 shown in FIG. 10 is 3T, it is longer than the first detection period 2T, but during this failure period 3T Since the operation notification signal (the date and time in the log information) is included in any range corresponding to the first detection period 2T, the MPU 11 determines that no abnormality has occurred in the person watched during the failure period. Is done. For this reason, the content of the e-mail notified after the failure recovery notification is that no abnormality has occurred in the watched person during the failure period.

On the other hand, in the time chart shown in FIG. 11, the determination of failure occurrence and failure recovery is the same as in the case shown in FIG. 10, but the operation notification signal and its date / time included in the log information during the failure period are shown in FIG. It is different from the case shown. That is, in the case shown in FIG. 11, the operation notification signal (T) is within the range of the first detection period 2T from the time of receiving the fourth connection confirmation signal S13 to the time of receiving the sixth connection confirmation signal S15 during the failure period. Therefore, the MPU 11 determines that an abnormality has occurred in the person watched during the failure period. Therefore, in the case of the time chart shown in FIG. 11, the content of the e-mail notified after the failure recovery notification is that an abnormality has occurred in the watched person during the failure period (see FIG. 4F).

The first to third flowcharts of FIGS. 12 to 14 are a series of the flow of a series of processes performed by the monitoring apparatus 10 described above. The fourth and fifth flowcharts of FIGS. 15 and 16 are a series of processes performed by the monitoring server 20. The processing of the monitoring service method of the monitoring service system 1 will be described according to these flowcharts. The first to third flowcharts start from a state where the watching device 10 has already been started (a state where the watching program P2 has been started), and the fourth and fifth flowcharts have already been started by the watching server 20 (the watching service program P11 is installed). It is intended to start from the (started state).

First, the first flowchart of FIG. 12 shows processing related to the operation notification signal in the watching device 10, and the watching device 10 detects whether or not the operation notification signal output from the television device 5 has been acquired (S1). ). When the operation notification signal has not been acquired (S1: NO), the operation is waiting for acquisition (waiting for the user to operate the television device 5), and when the operation notification signal is acquired (S1: YES), the acquired operation notification signal is acquired. Watch over and transmit to the server 20 (S2). Further, the presence or absence of free space in the second memory 16 is detected (S3), and if there is free space (S3: YES), the watching device 16 sends the acquired new operation notification signal to the log table 17 of the second memory 16. (S5), and when there is no free space (S3: NO), the oldest log information is deleted from the log table 17 (S4), and the latest operation notification signal is stored in the log table 17 (S5). Then, the watching device 10 determines whether or not the watching program P2 is ended (S6). If it is not ended (S6: NO), the process returns to the first stage (S1), and if it is ended (S6: YES). Then, a series of processing is completed.

The second flowchart in FIG. 13 shows processing related to detection of the connection state with the television device 5. First, is the monitoring device 10 maintained in connection with the television device 5 except for the power-off operation? Is determined (S10). When it is determined that the connection is not maintained (S10: NO), the watching device 10 watches the user device error signal and transmits it to the server 20 (S11), and the transmission of the user device error signal is performed by the television device 5. It continues until the connection with is confirmed. If it is determined that it is connected (S10: YES), the watching device 10 determines whether the watching program P2 is ended (S12). If it is not ended (S12: NO), the first stage If it returns to (S10) and is complete | finished (S12: YES), a series of processes will be complete | finished.

The third flowchart of FIG. 14 shows processing related to the transmission of the connection confirmation signal. First, the monitoring device 10 watches the connection confirmation signal and transmits it to the server 20 (S20), and then corresponds to the connection confirmation signal transmitted. It is determined whether or not a connection response signal has been received (S21). When the connection response signal is received (S21: YES), the watching device 10 determines whether the watching program P2 is finished (S22), and if not finished (S22: NO), the connection confirmation signal is obtained in the stage of S20. It is determined whether or not the time since the transmission has reached the unit period (S23). If the unit period has not been reached (S23: NO), the process returns to the step S22. If the unit period has been reached (S23: YES), the process returns to the first stage (S20), and the connection confirmation signal is transmitted again. become.

On the other hand, when the connection response signal is not received (S21: NO), a failure occurs, and the monitoring apparatus 10 specifies the transmission date and time of the latest connection confirmation signal (S24), and reaches the unit period from the specified date and time. It is determined whether or not (S25). If it has not arrived (S25: NO), it will be in a unit period waiting state, and if it has arrived (S25: YES), it will further watch the connection confirmation signal and send it to the server 20 (S26). Then, the monitoring device 10 determines whether or not a connection response signal corresponding to the transmitted connection confirmation signal has been received (S27), and when the connection response signal is not received (S27: NO), the failure is still restored. Therefore, it is determined whether or not the time from the most recent connection confirmation signal transmission (step S25) has reached the unit period (S28).

If the unit period has not been reached (S28: NO), the unit waits for arrival. If the unit period has been reached (S28: YES), the process returns to the connection confirmation signal transmission stage (S26). On the other hand, when the connection response signal corresponding to the connection confirmation signal transmitted in the step S27 is received (S27: YES), it means that the failure has been recovered, and the watching device 10 reads the log information during the failure period and watches it. It is transmitted to the server 20 (S29), and it is determined whether or not the time from the most recent connection confirmation signal transmission (step S26) has reached the unit period (S30).

If the unit period has not been reached (S30: NO), the system waits for arrival. If the unit period has been reached (S30: YES), the process returns to the connection confirmation signal transmission stage (S20). The watching device 10 keeps watching such processing until the program P2 is finished (S22: YES). Note that the monitoring apparatus 10 performs the processes of the first to third flowcharts described above in parallel.

15 is a basic processing procedure of the watching server 20. Although not shown in the fourth flowchart, the monitoring server 20 receives operation notification signals from the monitoring device 10 as needed according to the first flowchart described above. Further, according to the second flowchart described above, the monitoring server 20 receives a user device error signal from the monitoring device 10 depending on the situation, and when receiving the user device error signal, the user device (television device 5) has some trouble. When the watcher who watches over the person who operates the user device is notified (see FIG. 3C) and no user device error signal is received, the fact that the device has been recovered from the failure is notified. Notification (see FIG. 3E) is made.

In the fourth flowchart, first, the watching server 20 determines whether or not a connection confirmation signal transmitted from the watching device 10 has been received (S40). If it has not been received (S40: NO), it will be in a waiting state for reception, and if it has been received (S40: YES), the watch server 20 starts measuring the time after receiving the connection confirmation signal (S41), The connection response signal is watched and transmitted to the apparatus 10 (S42).

Then, the monitoring server 20 determines whether or not the above-described abnormality determination condition (first abnormality determination condition, second abnormality determination condition) is satisfied based on the reception status of the operation notification signal or the like (S43). If the condition is satisfied (S43: YES), a watch alert (notification that an abnormality has occurred in the watched person) is transmitted (notified) to a predetermined watcher with reference to the user DB 30 (S44). When the abnormality determination condition is not satisfied (S43: NO), the monitoring server 20 determines whether or not the measured time exceeds the unit period (S45), and when it does not exceed (S45: NO), the monitoring service program It is determined whether P11 is terminated (S46). If not terminated (S46: NO), it is determined whether a connection confirmation signal is received (S47).

If the connection confirmation signal has been received (S47: YES), the monitoring server 20 returns to the stage (S41) of starting the time measurement after receiving the connection confirmation signal, while receiving the connection confirmation signal. If not (S47: NO), the process returns to the step (S45) of determining whether or not the measured time exceeds the unit period. If the measured time exceeds the unit period (S45: YES), the system has failed, so the watching server 20 performs the process shown in the fifth flowchart shown in FIG.

In the fifth flowchart of FIG. 16, the watching server 20 determines that a failure has occurred (S50), and transmits a failure notification (see FIG. 4 (d)) to all watching people (S51). Then, the watching server 20 determines whether or not the connection confirmation signal transmitted from the watching device 10 has been received (S52), and if it has not been received (S52: NO), the failure continues. Waiting for reception. On the other hand, when the connection confirmation signal is received (S52: YES), it means that the failure has been recovered, and the monitoring server 20 starts measuring time after receiving the connection confirmation signal (S53), and the connection response signal. It is transmitted to the watching device 10 (S54), and it is determined whether or not the log information during the failure period transmitted from the watching device 10 is received (S55).

When the log information has not been received (S55: NO), it is in a reception waiting state. When the log information is received (S55: YES), an e-mail notifying failure recovery (see FIG. 3 (e)) is sent to the user DB 30 Is sent to all watchers registered in (S56). Then, the watching server 20 determines whether or not the received log information satisfies the above-described abnormality determination condition (first abnormality determination condition, second abnormality determination condition) (S57), and if satisfied (S57: YES), A watch alert (see FIG. 3 (f)) indicating that an abnormality has occurred in the person watched during the failure period is notified to the watchers K1 to K3 (S58), while the abnormality judgment condition is not satisfied (S57). : NO), the person K1 to K3 watching that no abnormality has occurred in the person being watched during the failure period is notified (S59), and the process returns to the first stage of the fourth flowchart of FIG. The watching server 20 continues such processing until the watching service program P11 is terminated (S46: YES).

As described above, in the first embodiment, the watching server 20 can discriminate between a state in which an abnormality has occurred in the person being watched and a state in which a failure has occurred in the system, and notifies the person watching the result of the judgment. Therefore, it is possible to enhance the trust of the watcher with respect to the watch service system 1. Furthermore, when a failure has occurred in the system, the server 20 notifies the person who watches the situation of the person being watched over during the failure period, so that it can be provided to those who watch a greater sense of security.

The contents according to the first embodiment are not limited to the above-described forms, and various modifications can be applied. For example, the user device operated by the watched person M1 is not limited to the television apparatus 5 shown in FIG. 1, but is a device to be operated by the watched person M1, and indicates that there has been a user operation. The model is not limited as long as the operation notification signal can be output and the monitoring device 10 can be connected. As user equipment that can satisfy such specifications, refrigerators, rice cookers, electric / electronic cooking utensils (microwave ovens, microwave ovens, etc.) electric pots, washing machines, vacuum cleaners, air conditioners, lighting fixtures, and the like are candidates.

In addition to the direct connection between the connection terminals as described above, the connection between the user device and the monitoring apparatus 10 is performed by connecting the two using a wire such as a connection cable or by connecting them both wirelessly. Of course it is also possible. Furthermore, the connection standard is not limited to HDMI (registered trademark), but a standard according to wired LAN, a standard according to wireless LAN, Bluetooth, infrared communication (IrDa), Zigbee (registered trademark), USB, Either NFC (a kind of short-range wireless communication standard), TRANSFERJET (registered trademark), or the like may be applied. In addition to the stick shape, the shape of the watching device 10 can be a box shape or a plate shape.

Furthermore, when the user device and the monitoring device 10 are connected by radio or the like, a configuration in which a plurality of user devices and the monitoring device 10 are connected may be employed. In this case, the monitoring device 10 is not required until the operation notification signal transmitted from the user device is identified for each device. For example, when two devices, a television device and a refrigerator, are connected to the watch device 10, the television device is turned on, a certain channel is viewed for a long time, and an operation notification signal is received from the television device. If the watched person opens the door to remove the drink from the refrigerator in a situation where it has not been sent, an operation notification signal will be sent from the refrigerator, so the operation notification signal from this refrigerator will cause an abnormality to the watched person. Since it is confirmed that no occurrence has occurred, the monitoring device 10 does not have to distinguish operation notification signals for each user device.

In addition, the monitoring device 10 can be incorporated into the user device so that the monitoring device 10 alone does not have independence, other than being connected as an external device of the user device. In this case, the monitoring device 10 is connected to the internal circuit of the user device as a communication module having the function of the communication terminal device inside the user device to be incorporated, and the monitoring device 10 functioning as the communication module is used by the user. By including the device in a state where it is connected to the internal circuit, the user device itself can perform processing equivalent to each processing related to watching performed by the monitoring device 10 described above.

In addition to using both the first abnormality determination condition and the second abnormality determination condition described above, it is possible to use only one of the conditions for determining whether an abnormality has occurred in the watched person. It is. Furthermore, it is of course possible to use abnormality determination conditions other than those described above. For example, for a user who watches the television device 5 every day (a person who is watched over), the server 20 watches the reception detection of the operation notification signal indicating the power-on operation every day to watch the TV program every day. A person who is watching over may be able to determine that an abnormality has occurred in a situation where the power is not turned on today. As another example, even when a user who regularly performs a channel switching operation (a person to be watched) is left without any operation after the power is turned on today, the power is turned on. After receiving the operation notification signal indicating the operation, the server 20 may monitor the reception detection of the operation notification signal during the detection period based on the unit period so that the occurrence of an abnormality can be found.

In addition, in order to further enhance the sense of security for the watcher of the watch service system 1, notify the watcher of the situation of the watched person in addition to the abnormal alarm (notification that an abnormality has occurred in the watched person). May be. For example, if the server 20 detects the reception of the operation notification signal indicating the first power-on operation of the day, it may be transmitted to the person watching the notification that “the power is turned on”. Furthermore, the content of the operation notification signal according to the reception status of the operation notification signal is transmitted to the watcher registered by the watch server 20 in addition to the case where the watch server 20 performs voluntarily as described above. It is also possible to perform when there is a (request). In this case, the watchers K1, K2, K3, etc. use the

communication devices

40, 41, 42, etc. owned by themselves to send a request signal related to the watch request to the watch server 20, and the watch server 20 The communication device that becomes the source of the request signal based on the reception status of the operation notification signal according to the reception of the signal, and the content determined based on the reception status (determination content such as occurrence of failure, abnormality in the watched person) Will be sent to. In the case of such a modification, there is a merit that the burden of transmission processing notified to the communication device of the person watched by the watch server 20 can be reduced. In addition to the watched person's family, siblings, relatives, and acquaintances, the person who watches the notice can also be an administrator / monitor of the local government where the watched person resides. Thus, when the notification of the watching server 20 is delivered to the administrator / monitor of the local government, the administrator / monitor of the local government who received the notification from the monitoring server 20 actually watches the person being watched over. It is instructed to go to the house of a person who is watched over by the residents of the residents' association and local welfare committee.

Furthermore, when securing the processing load of the watching device 10 and the memory capacity of the second memory 16, all operation notification signals output from the user device (television device 5) are stored in the log table 17 as log information. For example, the operation notification signals for the two most recent unit periods are always stored as log information in at least the log table 17, and when it is determined that a failure has occurred, the log information stored at that time is stored. The log information during the failure occurrence period may be stored in order while ensuring the above.

FIG. 17 shows a time chart according to the second embodiment of the present invention, and the second embodiment is characterized in that the time of the unit period can be appropriately changed according to the situation or the like. Since the basic system configuration of the second embodiment is the same as that of the first embodiment, the same reference numerals as those of the first embodiment are used for the reference numerals to describe the contents of the second embodiment. .

As described in the first embodiment, the monitoring server 20 includes unit period information in the monitoring setting information D20 (see FIG. 6). In the second embodiment, the monitoring server 20 includes the monitoring setting information D20. The specification is such that the operator can freely set and control the time of the unit period included in. When the operator changes the time of the unit period, processing for transmitting setting information (time specification information) specifying the changed time as the unit period from the communication module 22 to the monitoring device 10 is performed under the control of the MPU 21. (Such control processing of the MPU 21 is defined in the program content of the watching service program P11).

On the other hand, when receiving the setting information, the watching device 10 rewrites the unit period time in the watching process setting information D1 stored in the first memory 15 to the unit period specified by the received setting information. Thus, the CPU 11 performs processing for setting the time as a new unit period. When the new setting of the unit period time is performed as described above, the monitoring apparatus 10 controls the CPU 11 to send a connection confirmation signal based on the new unit period from the next unit period following the unit period in which the setting information is received. (Such control processing of the CPU 11 is defined in the program content of the watching program P2).

The time chart of FIG. 17 shows that the unit periods are sequentially changed to T, T / 2, and 2T. Specifically, the monitoring server 20 transmits the connection response signal S21 and then the next connection response signal. Until S22 is transmitted, the setting information specifying the unit period as T / 2 is watched and transmitted to the apparatus 10. By receiving this setting information, the monitoring device 10 transmits connection confirmation signals S13, S14, etc. at intervals of T / 2 from the next unit period.

Furthermore, the monitoring server 20 transmits to the monitoring apparatus 10 the setting information that designates the unit period as 2T from the transmission of the connection response signal S200 to the transmission of the next connection response signal S201. By receiving this setting information, the watching device 10 transmits a connection confirmation signal S102 and the like at intervals of 2T from the next unit period.

As described above, in the second embodiment, the unit period can be changed dynamically, so that the unit period is set for each time zone of the day, for each day of the week, and for each season in consideration of the lifestyle of the person being watched over. Can be changed. For example, as an example of changing the time of the unit period for each time slot of the day, the unit period is 1 minute from 4 o'clock to 7 o'clock, 1 hour from 7 o'clock to 21 o'clock, 7 o'clock from 21:00 to 4 o'clock the next day It is possible to specify how to specify time. In this example, the watched person frequently operates the user equipment in the time zone from 4 to 7 o'clock and tends to decrease the frequency of operation of the user equipment by going out to a medical institution or the like in the time zone from 7 o'clock to 21 o'clock. In addition, considering the fact that it is a bedtime time from 21:00 to 4 o'clock the next day, the above example is set (in this example, 21:00 to 4 o'clock the next day) During this time period, failure detection and abnormal detection of the watched person are not performed).

As an example of changing the time of the unit period for each day of the week, from Monday to Saturday, the unit period is changed for each time zone described above (the unit period is 1 minute and 7 o'clock from 4 to 7 o'clock). 1 hour from 21:00 to 7 hours from 21:00 to 4am the following day) On Sundays only, the unit period is 1 minute from 4am to 21:00, and the unit period is 7 hours from 21:00 to 4am the next day The way of designation is conceivable. In this example, since a medical institution or the like is closed on Sunday, there is a tendency to frequently operate the user equipment throughout the day.

Furthermore, as an example of changing the time of the unit period for each season, in the season from June to September (season from early summer to early autumn), the unit period is 1 minute from 17:00 to 19:00, and from 19:00 to 23:00 It is possible to specify that the unit period is 1 hour, 23:00 to 7:00 the next day, and the unit period is 8 hours. In the November to February season (autumn to winter season), 4 to 12 The unit period is 1 minute, the unit period is 1 hour from 12:00 to 20:00, and the unit period is 8 hours from 20:00 to 4 o'clock the next day. Such an example is a setting example in consideration of the wake-up time, activity time, and the like of a person to be watched depending on the season. In addition, in the season which is not mentioned as an example, the example for every time slot | zone mentioned above applies.

The time chart of FIG. 18 shows a modification of the second embodiment. In this modification, the setting information (time designation information) described above is included in the connection response signal that the watching server 20 periodically transmits. It is a feature. That is, the connection response signal S22 includes setting information for designating the unit period as T / 2, and the connection response signal S201 includes setting information for designating the unit period as 2T. The monitoring device 10 that receives the connection response signals S22 and S201 changes the unit period to T / 2 immediately after receiving the connection response signal S22 and transmits the next connection confirmation signal S13. Immediately after receiving the connection response signal S201, the unit period is changed to 2T and the next connection confirmation signal S102 is transmitted.

In this modification, even if the operator changes the time of the unit period, the setting information (time designation information) is not immediately watched and transmitted to the apparatus 10, but the operator changes the time of the unit period and then transmits it. The MPU 21 performs processing for including the setting information in the connection response signal to be transmitted and transmitting it to the watching device 10. By doing in this way, the number of signals transmitted to the watching device 10 can be reduced compared to the case of FIG. 17, and the time of the unit period can be changed with good timing. Further, in this modification, when the device 10 watches the connection response signal including the setting information, the CPU 11 performs processing for changing the unit period to a new time immediately after receiving the connection response signal. In the second embodiment (including the modification of the second embodiment), the modification of the first embodiment described above can also be applied.

FIGS. 19 and 20 show time charts according to the third embodiment of the present invention. In the third embodiment, the monitoring device 10 transmits a unit confirmation signal transmitted every unit period within the latest unit period. It is characterized in that the operation notification signal acquired in step 1 is transmitted as log information. 19 corresponds to the contents of the time chart of FIG. 8 of the first embodiment, and the time chart of FIG. 20 corresponds to the time chart of FIG. 9 of the first embodiment. Since the basic system configuration of the third embodiment is the same as that of the first embodiment, the same reference numerals are used to describe the contents of the third embodiment. .

In the third embodiment, as described above, the monitoring device 10 collectively transmits an operation notification signal as log information to the monitoring server 20 for each unit period. Therefore, in the monitoring server 20, processing related to reception is organized for each unit period. Therefore, the processing efficiency can be improved. In order to perform such processing, the monitoring device 10 stores the log information of the unit period in which the operation notification signals acquired during the unit period are collected in the second memory 16, and the log information of the unit period is stored. At the same time as the connection confirmation signal, it transmits to the watching server 20.

The details will be described based on the time chart of FIG. 19. At the same time as the second connection confirmation signal S11 transmitted from the monitoring device 10, t1 (transmission time of the first connection confirmation signal S10) to t2 (second connection confirmation signal). The server 20 receives and monitors the log information of the unit period T of the transmission time of the signal S11. Hereinafter, the log information of the unit period T of t2 to t3 is received simultaneously with the third connection confirmation signal S12. Simultaneously with the fourth connection confirmation signal S13, the log information of the unit period T from t3 to t4 is received. However, in the unit period T from t4 to t5 and the unit period T from t5 to t6, the monitoring device 10 has not acquired the operation notification signal, so that the monitoring server 20 receives the fifth connection confirmation signal S14 and the sixth Since the log information of the unit period is not received when the connection confirmation signal S15 is received, an abnormality occurs in the person who is watched according to the first abnormality determination condition described above at the time after the reception of the sixth connection confirmation signal S15. The watch alert (see FIG. 3A) is notified.

In the time chart of FIG. 20, the server 20 receives the log information of the unit period T from t1 to t2 simultaneously with the second connection confirmation signal S11 transmitted from the monitoring device 10, and hereinafter, the third connection confirmation signal is received. Simultaneously with S12, log information of the unit period T from t2 to t3 is received, and simultaneously with the fourth connection confirmation signal S13, log information of the unit period T from t3 to t4 is received, and the fifth connection confirmation signal S14 and At the same time, the log information of the unit period T from t4 to t5 is received, but the log information of the unit period is not received when the sixth connection confirmation signal S15 is received. Further, since the log information for each unit period in the range from t2 to t5 does not include an operation notification signal indicating a power-off operation, the watch server 20 receives a time point after receiving the sixth connection confirmation signal S15. Therefore, it is determined that an abnormality has occurred in the person to be watched according to the second abnormality determination condition described above, and a watch alert is notified. In the third embodiment, the modification of the first embodiment described above can also be applied.

INDUSTRIAL APPLICABILITY The present invention can be suitably used when it is desired to distinguish between the occurrence of an abnormality in the watched person and the occurrence of a failure in the system when providing a watch service for watching the watched person. It is.
