The “monitoring area state abnormality” includes a state abnormality of a person living in this dwelling unit (hereinafter, “target person”) and a crime prevention state abnormality. In addition, “subject's condition abnormal” means that the subject's condition is not normal, and there is a cause in the subject itself (including physical and mental causes) or a cause other than the subject There may be some cases (including cases where equipment such as the notification broadcast receiver 3 is broken, or where freedom is restricted by illegal intruders, etc.), but in this embodiment, the target person's own sudden physical condition, etc. Thus, it is assumed that the target person is unable to move by himself / herself. In addition, the “security abnormal state” indicates that the state of the dwelling unit is not normal from the viewpoint of crime prevention, and in this embodiment, there is a state where there is a person who has entered the dwelling unit without permission (hereinafter referred to as an intruder). It is assumed that

  Here, in order to determine the presence / absence of a state abnormality in the monitoring area, in the present embodiment, various types of information acquired using the notification broadcast receiver 3 are used.

Thereby, even in a situation in which the notification broadcast cannot be received from the center device 1, the FM radio or the like can be received by the antenna 45.

(processing)
Next, each process which the notification broadcasting system 100 comprised in this way performs is demonstrated.

(General processing)
First, general processing will be described. This process is a process for performing announcement broadcasting. First, when it is desired to broadcast a notification broadcast from the notification broadcast receiver 3, the center apparatus 1 sends a control signal including the address of the notification broadcast receiver 3 to be broadcast and the type of notification broadcast (emergency broadcast or general broadcast) to the notification broadcast of the dwelling unit. Transmit to the receiver 3. The notification broadcast receiver 3 that has received the control signal compares the address included in the control signal with its own address stored in advance, and if it matches, the notification broadcast receiver 3 receives the notification broadcast received after the control signal. The broadcast is output from the speaker 34 via the volume control unit 32 and the amplifier 33. At this time, if the type of notification broadcast included in the control signal is emergency broadcast, the broadcast is output at the maximum volume regardless of the volume adjustment state of the volume switch 37e, and it is ensured that the resident is in an emergency situation. Inform. When the type of notification broadcast is general broadcast, the broadcast is broadcast at a volume corresponding to the adjustment state of the volume switch 37e. Further, when a notification broadcast is received, it can be stored in the audio information storage unit 41 and reproduced by a resident's operation to confirm the broadcast content. Note that the receiver ID may be used as this address, or an address for notification broadcasting different from the receiver ID may be set.

(Sensor detection count storage process)
Next, the sensor detection frequency storage process will be described. This process is a process for storing the number of sensor detections. First, the detection unit 35 monitors the movement of a person in the monitoring area, and accumulates the detected number of times in the memory 40 of the notification broadcast receiver 3 every time the detection unit 35 detects the movement of the person. The notification broadcast receiver 3 transmits a detection signal including the number of times stored in the memory 40 at a predetermined time interval and the receiver ID of the notification broadcast receiver 3 to the center device 1. The number of times stored in the memory 40 is initialized. And the center apparatus 1 which received this detection signal uses the said detection signal as information corresponding to the date which received the said detection signal in the record of receiver ID contained in the said detection signal in input history DB15a of the center apparatus 1. Stores the number of times included. Thereafter, every time the notification broadcast receiver 3 transmits a detection signal to the center device 1 at a predetermined time interval, the center device 1 executes the same storing process, and the number of times is accumulated in the input history DB 15a each time. As a result, the number of sensor detections, which is the accumulated value of the number of times, can be stored in the input history DB 15a.

(Absence status acquisition process)
Next, the absence state acquisition process will be described. This process is a process for acquiring the absence state. First, as an initial setting, information on the absence flag is stored in the input history DB 15a of the center device 1, and the backlight of the absence switch 37b is turned off. When the target person leaves the dwelling unit, the target person presses the answering switch 37b before leaving the dwelling unit. When the answering switch 37b is thus pressed, the backlight of the answering switch 37b is turned on. By confirming that the backlight of the answering switch 37b is turned on in this way, the subject can easily grasp that the answering switch 37b has been properly pressed.

  When the answering switch 37b is pressed, a control signal is output to the control unit 39 of the notification broadcast receiver 3, and the control unit 39 of the notification broadcast receiver 3 that has received the control signal receives the control broadcast receiver 3. 3 is sent to the center apparatus 1 including the receiver ID of 3 and the information on the absence flag ON. And the center apparatus 1 which received this absence state signal sets the absence flag ON included in the absence state signal as an absence flag in the record of the receiver ID included in the absence state signal in the input history DB 15a of the center apparatus 1. Store information. Then, “ON” is displayed in a column corresponding to the absence flag item on the display of the center device 1.

  When the subject returns home and cancels the absence state, the subject presses the absence switch 37b again, and thereby the backlight of the absence switch 37b is turned off, and the receiver of the notification broadcast receiver 3 is turned off. An absence state signal including the ID and information about the absence flag OFF is transmitted to the center device 1. Then, “OFF” is displayed in the column corresponding to the absence flag item on the display of the center device 1. In this way, the subject can freely switch the absence state simply by pressing the absence switch 37b.

  Here, the time interval at which the detection signal is transmitted to the center apparatus 1 may be different between the case where the absence flag is OFF and the case where it is ON in the above-described sensor detection count storage processing. That is, when detection by the detection unit 35 is performed when the absence flag is ON, there is a high possibility that an intruder exists in the monitoring area. Therefore, the detection signal waits for a predetermined time interval as described above. From the viewpoint of early detection of an intruder, it is preferable to immediately transmit a detection signal rather than transmitting. In the present embodiment, it is assumed that when the absence flag is ON, the detection signal is immediately transmitted to the center apparatus 1 when the detection unit 35 detects a person's movement.

(Input acceptance process)
Next, an input reception process executed by the notification broadcasting system 100 configured as described above will be described. FIG. 6 is a flowchart of an input reception process executed by the notification broadcasting system 100 (steps are abbreviated as “S” in the description of each process below). The execution timing of this input reception process is arbitrary, and is activated when, for example, the notification broadcast receiver 3 is turned on.

  As shown in FIG. 6, first, the control unit 39 of the notification broadcast receiver 3 stands by until the above-described predetermined timing arrives (SA1, No). Specifically, the control unit 39 of the notification broadcast receiver 3 monitors whether or not the communication unit 30 of the notification broadcast receiver 3 has received the input promotion signal transmitted from the communication unit 17 of the center device 1. When it is determined that the input promotion signal has been received, it is determined that a predetermined timing has arrived. And when it determines with the predetermined | prescribed timing having come (SA1, Yes), the control part 39 of the notification broadcast receiver 3 promotes the input of the energy switch 37a with respect to a subject by lighting the lighting part 42. (SA2).

  Next, the control unit 18 of the center apparatus 1 stores the input standby information in association with the item of the current date in the input history DB 15a (SA3). Specifically, the current date (in this embodiment, it is assumed that it is October 17) is acquired by a known method, and the acquired current date and input standby information are stored in all receiver IDs. Correspondingly, it is stored in the input history DB 15a. The input history information stored in the input history DB 15a in this way is displayed on the display of the center device 1 as shown in FIG. Therefore, after the processing of SA3, the input standby information symbol “triangle” is displayed on the left side of the column corresponding to the item of the current date on the display of the center device 1.

  Next, the input information acquisition unit 18a of the center device 1 determines whether or not there is an input from the energy switch 37a (SA4). Specifically, when the input by the spirit switch 37 a is performed, the control unit 39 of the notification broadcast receiver 3 generates an input signal including the receiver ID of the notification broadcast receiver 3 to generate the center device 1. Send to. And the input information acquisition part 18a of the center apparatus 1 determines with having input by the energy switch 37a, when this input signal is received. In particular, in the present embodiment, it is assumed that a plurality of modes of the first mode and the second mode can be performed as modes of input by the energy switch 37a. Among these, the “first mode” is a mode for notifying that the target person is well, for example, a mode in which the spirit switch 37a is input only once. The “second mode” is a mode for notifying a predetermined state other than the first mode, for example, a mode in which the subject is aware of his / her condition abnormality and seeks help from others. It is assumed that the energy switch 37a is continuously input for a predetermined time or longer.

  And when the communication part 17 has not received the 1st input signal or the 2nd input signal, the input information acquisition part 18a of the center apparatus 1 determines with there being no input (SA4, No), and performs an input reception process. It is determined whether a predetermined time has elapsed from the start (SA5), and the processes of SA4 and SA5 are repeatedly executed until the predetermined time elapses (SA5, No).

  And when the communication part 17 receives a 1st input signal or a 2nd input signal, it determines with having input (SA4, Yes), and the state abnormality determination part 18b is the energy switch 37a by a 1st aspect. Is determined (SA6). Specifically, when it is determined that the received input signal is the first input signal, it is determined that the energy switch 37a is input according to the first aspect, and the received input signal is the second input signal. When it determines, it determines with the energy switch 37a having been input by the 2nd aspect.

  And when it determines with the energy switch 37a having been input by the 1st aspect (SA6, Yes), the input information acquisition part 18a analyzes the said input signal, and specifies receiver ID contained in the said input signal. Then, the input information acquisition unit 18a replaces the input waiting information stored in association with the item of the current date in the record of the receiver ID of the specified notification broadcast receiver 3 in the input history DB 15a. And the input confirmation information symbol “double circle” is displayed instead of the input standby information symbol “triangle” on the left side of the column corresponding to the item of the current date on the display of the center device 1 (SA7). For example, the owner of the receiver ID 001 and the receiver ID 003 shown in FIG. 3B is the person who performed the input of the energy switch 37a because the input confirmation information symbol is displayed in the field. Finally, the lighting unit 42 lit in SA2 is turned off (SA8), and the input receiving process is terminated.

  On the other hand, when it is determined that the energy switch 37a is not input according to the first aspect (SA6, No), that is, when it is determined that the energy switch 37a is input according to the second aspect, the speaker of the center device 1 (illustrated) A predetermined alarm is output from (omitted) (SA9), the lighting unit 42 is turned off (SA8), and the input acceptance process is terminated. The specific content of the alarm output is arbitrary. For example, the alarm signal is transmitted from the center device 1 to the notification broadcast receiver 3 that has transmitted the second input signal, and the notification broadcast receiver that has received the alarm signal is received. Alarm output may be performed from the speaker 34 provided in the third stage. Further, an alarm signal is transmitted to the other notification broadcast receiver 3 other than the notification broadcast receiver 3 that has transmitted the second input signal, and an alarm is output from the speaker 34 provided in the other notification broadcast receiver 3. By performing the above, it is possible to prompt the owner of the other notification broadcast receiver 3 to confirm whether or not the target person has a state abnormality. For example, the notification broadcast receiver 3 of the other target person who requests confirmation of the abnormality when the abnormality occurs in each target person and the receiver ID, name, and address of the notification broadcast receiver 3 of each target person. The subject-related table configured by associating the receiver ID, name, and address with each other is stored in the memory 15 in advance. Then, the receiver ID, name, and address of another subject are acquired with reference to the target person related table, and an alarm signal including the acquired receiver ID, name, and address is generated and transmitted. Request confirmation from other subjects. At this time, by outputting the name and address of the subject in which the abnormality has occurred from the notification broadcast receiver 3 of the other subject, it is possible to identify the subject in which the abnormality has occurred.

  If the predetermined time has passed without input by the energy switch 37a (SA5, Yes), it is determined that there is no input by the energy switch 37a on that day, and the lighting unit 42 is turned off (SA8). To finish the input acceptance process.

(Determination process)
Next, a determination process executed by the notification broadcasting system 100 will be described. FIG. 7 is a flowchart of the determination process. The execution timing of this determination process is arbitrary. For example, it may be executed immediately after the above-described input reception process is completed, may be executed at a predetermined time on each day, or may be performed by an administrator. (For example, timing when the administrator clicks a determination process activation icon (not shown) displayed on the display of the center device 1).

  First, the state abnormality determination unit 18b of the center device 1 acquires the input history information stored in the input history DB 15a (SB1). Then, the presence / absence of the notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days is determined (SB2). As this predetermined number of days, since it is not continuously confirmed that the input by the energy switch 37a has been performed, a number that can be estimated that there is a high possibility that a state abnormality has occurred in the subject is set. Although the specific number is arbitrary, for example, the predetermined number of days is 3 days. In this way, by determining the presence or absence of the notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days in succession, it is possible to identify the notification broadcast receiver 3 that is likely to have a state abnormality in the target person. Is possible.

  Here, as shown in FIG. 3A, the notification broadcast receiver 3 with the receiver ID 002 stores the input standby information continuously for three days from October 15 to October 17. Therefore, the state abnormality determination unit 18b determines that there is the notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days continuously. If it is determined that there is a notification broadcast receiver 3 in which input standby information is stored for a predetermined number of days continuously (SB2, Yes), the number of sensor detections for the predetermined number of days in the notification broadcast receiver 3 is less than the predetermined number of times. Whether or not (SB3). As the predetermined number of days and the predetermined number of times, the number of days and the number of times that it is possible to estimate that there is a high possibility that a condition abnormality has occurred in the target person because the movement of the target person has not been detected more than a specific number of times in a specific period However, in the present embodiment, the predetermined number of days is set as three days, and the predetermined number of times is set as three.

  Here, as shown in FIG. 3 (a), in the notification broadcast receiver 3 having the receiver ID 002, the number of times of sensor detection is less than 3 times in any of the three days from October 15 to October 17. It is. Therefore, the state abnormality determination unit 18b determines that the number of sensor detections for a predetermined number of days is less than the predetermined number. If it is determined that the number of sensor detections for the predetermined number of days is less than the predetermined number (SB3, Yes), the state abnormality determination unit 18b determines that there is a high possibility that the target person has a state abnormality, and the predetermined number of days. Is changed to non-input information (SB4). Specifically, the state abnormality determination unit 18b is an input standby information symbol stored in association with the receiver ID of the notification broadcast receiver 3, and is associated with each date included in the predetermined number of days. In place of the stored input standby information symbol, non-input information is stored, and on the left side of the column corresponding to each date on the display of the center device 1, the input standby information symbol "triangle" is replaced with the non-input information symbol “X” is displayed.

  Then, in order to confirm the safety of the subject, an email is transmitted to the subject, the relative of the subject, etc. (SB5). Specifically, an address table (not shown) stored in association with the subject's name and the mail address of the subject or the relative of the subject is stored in advance in the memory 15 and the address table is referred to. The mail address is specified, the mail is automatically transmitted to the specified mail address, and the determination process is terminated. In this embodiment, in order to confirm the safety of the subject, an email is automatically transmitted to the subject, the relative of the subject, etc., but the safety may be confirmed by other methods. . For example, the administrator may actively contact the subject's telephone number or the like, or the staff may directly visit the subject's dwelling unit.

  On the other hand, when it is determined that there is no notification broadcast receiver 3 in which the input standby information is stored continuously for a predetermined number of days (SB2, No), or when it is determined that the number of sensor detections for the predetermined number of days is not less than the predetermined number (SB3, No), the non-output signal number determination unit 18c acquires the number of non-output signals (SB6). Specifically, first, the non-output signal number determination unit 18c acquires the receiver ID of the notification broadcast receiver 3 subjected to the determination from the input history DB 15a, and outputs the unoutput including the acquired receiver ID. A signal number request signal is generated, and the generated non-output signal number request signal is transmitted to the notification broadcast receiver 3 via the communication unit 17. And the control part 39 of the notification broadcast receiver 3 which received this non-output signal number request signal analyzes the received non-output signal number request signal, and sets receiver ID contained in the non-output signal number request signal. It is determined, and it is determined whether or not the specified receiver ID matches its own receiver ID, and the number of unoutput signals is transmitted only when it matches. Specifically, the control unit 39 of the notification broadcast receiver 3 refers to the information stored in the notification broadcast signal storage unit 40a of the memory 40 and specifies the number of unoutput signals. Then, a response signal including the number of non-output signals and its own receiver ID is transmitted to the broadcast center via the communication unit 30 of the notification broadcast receiver 3. And the non-output signal number determination part 18c of a broadcast center analyzes this response signal, and specifies receiver ID contained in the said response signal, and the number of non-output signals.

  Next, the non-output signal number determination unit 18c compares the number of non-output signals acquired in SB6 with a predetermined number stored in the memory 15 of the center device 1, and determines whether or not the number of non-output signals exceeds the predetermined number. Is determined (SB7). As this predetermined number, since the notification broadcast signal is not output, a number that can be estimated that the target person is likely to have a state abnormality is set, and the specific number is arbitrary. For example, five are set. If it is determined that the number of non-output signals exceeds the predetermined number (SB7, Yes), the state abnormality determination unit 18b determines that there is a high possibility that the subject has a state abnormality. In order to confirm safety, an e-mail is transmitted to the target person, a relative of the target person, etc. (SB5). Note that a specific method of transmitting mail can be performed in the same manner as the processing of SB5 described above, and thus detailed description thereof is omitted.

  On the other hand, when it is determined that the number of non-output signals does not exceed the predetermined number (SB7, No), the state abnormality determination unit 18b determines that the target person is unlikely to have a state abnormality, and ends the determination process. To do.

(Correspondence result storage processing)
Next, the correspondence result storage process executed by the notification broadcasting system 100 will be described. FIG. 8 is a flowchart of the correspondence result storage process. This correspondence result storing process is roughly information indicating the means by which the administrator actually confirmed the safety of the target person after confirming the safety of the target person in SB5 of FIG. Is a process for storing in the memory 15 of the center device 1. The execution timing of the correspondence result storage process is arbitrary, and in this embodiment, the notification broadcast reception in which the administrator executes the correspondence result storage process in the input history table shown in FIG. 3 displayed on the display is received. This is executed when the receiver ID column of the machine 3 is clicked.

  First, the state abnormality determination part 18b acquires a correspondence result (SC1). As a specific method for acquiring the correspondence result, for example, there is a method of receiving an input of the correspondence result from the administrator. In other words, when the administrator clicks on a column in the display where the input standby information symbol is stored, a check list indicating various correspondence results is displayed on the display. The contents of this checklist are arbitrary, but in this embodiment, “contact from the person”, “contact from the family”, “contact from the neighborhood”, “the staff meets the person”, and “the staff "Family and visit" and "Other" items are displayed. Then, when the administrator clicks an item corresponding to the actual correspondence result from these items and checks it, the state abnormality determination unit 18b can obtain the correspondence result. In addition, when the administrator checks the “other” item, the administrator can input a specific response result, and the state abnormality determination unit 18b inputs the response result input in this way. Can be acquired.

  Next, the control unit 18 of the center device 1 changes the non-input information of the item corresponding to the clicked field to the confirmed information (SC2). Specifically, the control unit 18 stores the confirmed information in place of the non-input information stored in association with the receiver ID of the specified notification broadcast receiver 3 in the input history DB 15a. As shown in (c), the confirmed information symbol “square” is displayed on the display of the center apparatus 1 in place of the uninput information symbol “X”. This completes the correspondence result storage process. The administrator can confirm the specific contents of the correspondence result by clicking again on the column in which the confirmed information is stored.

(Security processing)
Next, a crime prevention process executed by the notification broadcasting system 100 will be described. FIG. 9 is a flowchart of the security process. This security process is generally a process for detecting the presence of an intruder who has entered a dwelling unit where the subject is absent. The execution timing of this crime prevention process is arbitrary, and is activated when, for example, the notification broadcast receiver 3 is turned on. The security process described below is executed for each notification broadcast receiver 3.

  As shown in FIG. 9, first, the absence state acquisition unit 18d refers to the input history DB 15a to determine whether or not the absence flag of the notification broadcast receiver 3 is ON (SD1). If the absence flag is not turned on, the process waits until the absence flag is turned on (No in SD1). When the absence flag is turned on (SD1, Yes), the absence state acquisition unit 18d determines whether the detection unit 35 has detected a person's movement (SD2). Specifically, when the center apparatus 1 receives the above-described detection signal transmitted from the notification broadcast receiver 3, it is determined that the movement of the person has been detected. Actually, considering the possibility that the subject stays in the dwelling unit for a predetermined time after pressing the answering switch 37b, after the absence flag is turned on (SD1, Yes), after the elapse of the predetermined time You may perform the process of SD2. And when the detection part 35 has not detected a human motion (SD2, No), the absence state acquisition part 18d refers to the input history DB 15a again, and the absence flag of the notification broadcast receiver 3 is turned OFF. It is determined whether or not (SD3). And when the absence flag is OFF (SD3, Yes), that is, when the subject returns home and presses the absence switch 37b again, it is determined that there was no intruder during absence, and the security process. Exit.

  On the other hand, when the absence flag has not yet been turned off (SD3, No), that is, when the subject has not returned home, the detection unit 35 detects the movement of the person or the subject has returned home. The processing of SD2 and SD3 is repeatedly executed until the absence flag is set to OFF. When the detection unit 35 detects a person's movement (SD2, Yes), the control unit 18 of the center apparatus 1 detects the movement of the person even though the target person is absent. It is determined that there is a high possibility that an intruder exists in the dwelling unit, and a recording / recording request signal including the receiver ID of the notification broadcast receiver 3 is transmitted. The notification broadcast receiver 3 that has received the recording / recording request signal determines whether the receiver ID included in the recording / recording request signal matches the receiver ID of the notification broadcast receiver 3. First, the microphone 36a and the camera 36b are activated to start recording and recording (SD4).

  And the control part 39 of the said notification broadcast receiver 3 includes receiver ID of the said notification broadcast receiver 3 in the audio | voice signal and video signal which were generated when the said notification broadcast receiver 3 recorded and recorded. It transmits to the center apparatus 1 (SD5). By outputting the audio signal and the video signal transmitted to the center apparatus 1 from the speaker or the display (both not shown) of the center apparatus 1 in this way, the administrator can check whether there is an abnormality in the monitoring area. It becomes possible.

  In addition, the center device 1 that has received the audio signal and the video signal transmits the audio signal and the video signal to the other notification broadcast receiver 3 and causes the other notification broadcast receiver 3 to output the audio signal and the video signal. It is possible to call attention to the owner of the other notification broadcast receiver 3. Specifically, the receiver ID, name, and address of the notification broadcast receiver 3 of each target person and the presence of the intruder when the intruder enters the dwelling unit where the notification broadcast receiver 3 is installed. A target person related table configured by associating the receiver ID, name, and address of the notification broadcast receiver 3 of another target person to be alerted with each other is stored in the memory of the center apparatus 1 in advance. And the control part 18 of the center apparatus 1 acquires receiver ID, a full name, and an address of another target person with reference to this subject related table, The said receiver ID, full name, and address which were acquired, The audio signal and the video signal acquired from the notification broadcast receiver 3 are included and transmitted. Then, the other notification broadcast receiver 3 that has received the signal determines whether or not the receiver ID included in the signal matches the receiver ID of the other notification broadcast receiver 3. The audio and video are output.

  Next, the control unit 18 of the center apparatus 1 outputs a predetermined alarm in order to make the presence of the intruder known to the surroundings of the notification broadcast receiver 3 or to intimidate the intruder (SD6). . Note that the specific contents of the alarm output are arbitrary, and the predetermined output from the speaker 34 of the notification broadcast receiver 3 or the speakers 34 of other notification broadcast receivers 3 is performed in the same manner as the input reception process of FIG. An alarm sound may be output.

(Confirmation result storage processing)
Next, a confirmation result storage process executed by the notification broadcasting system 100 will be described. FIG. 10 is a flowchart of the confirmation result storage process. This confirmation result storage process is generally performed by using the center (hereinafter referred to as confirmation result) indicating information indicating the means by which the administrator actually confirmed the presence / absence of a state abnormality in the monitoring area after the above-described crime prevention process shown in FIG. This is a process for storing in the memory 15 of the apparatus 1. The execution timing of the confirmation result storage process is arbitrary, and in this embodiment, the notification broadcast reception in which the administrator executes the confirmation result storage process in the input history table shown in FIG. 3 displayed on the display. This is executed when the receiver ID column of the machine 3 is clicked.

  First, the state abnormality determination unit 18b acquires a confirmation result (SE1). As a specific method for acquiring the confirmation result, for example, there is a method of receiving an input of the confirmation result from the administrator. In other words, when the administrator clicks on a column in the display where the status information symbol is stored, a check list indicating various correspondence results is displayed on the display. The contents of this checklist are optional, but in this embodiment, “contact from the person”, “contact from the family”, “contact from the neighborhood”, “the staff meets the person”, “the staff is the family And “Meetings”, “Staff visits the subject's home” and “Others” are displayed. Then, when the administrator clicks an item corresponding to the actual confirmation result from these items to check it, the state abnormality determination unit 18b can acquire the confirmation result.

  Next, the control unit 18 of the center apparatus 1 changes the status information of the item corresponding to the clicked column to the confirmed information (SE2). Specifically, the control unit 18 stores the confirmed information in place of the state information stored in association with the receiver ID of the specified notification broadcast receiver 3 in the input history DB 15a. The confirmed information symbol “square” is displayed on the display in place of the state information already stored. This completes the confirmation result storage process. The administrator can confirm the specific contents of the confirmation result by clicking again on the column in which the confirmed information is stored.

(effect)
Thus, according to the present embodiment, in addition to the state of the subject detected by the conventional human sensor, the presence or absence of the subject's active action such as input by the subject's spirit switch 37a is reflected in the abnormality detection. Compared to an anomaly detection system that uses only human sensors, for example, it is misjudged that there is no state abnormality in the subject based on the presence of a dynamic object other than the subject (for example, a pet). Therefore, it is possible to improve the accuracy of abnormality detection, and to use the existing notification broadcast receiver 3, it is possible to construct a system at low cost.

  In addition, by detecting the movement of a person in the monitoring area by a human sensor, it is possible to identify the presence or absence of a state abnormality in the monitoring area from the viewpoint of the movement of the target person or the movement of an intruder who has entered the monitoring area. Therefore, the accuracy of abnormality detection can be increased.

  In addition, when the target person is away, it is determined that there is an abnormality in the monitoring area when the motion sensor detects the movement of the person, so that the intruder has entered the monitoring area when the target person is away. It becomes possible to detect, and it becomes possible to improve the crime prevention accuracy of the monitoring area.

  In addition, if there is no input to the energy switch 37a within the predetermined period and the number of times the motion detection by the human sensor is detected is less than the predetermined number, it is determined that there is a state abnormality in the monitoring area. By assigning an appropriate weight to the number of times, it becomes possible to reflect the input status of the subject's usual spirit switch 37a in the determination of abnormality detection, so that the accuracy of abnormality detection can be further improved. .

  In addition, since a predetermined warning is output when it is determined that there is a status abnormality in the monitoring area, it is possible to notify the administrator or the residents in the vicinity of the dwelling unit of the occurrence of the status abnormality. Early detection is possible.

  In addition, when it is determined that there is an abnormality in the monitoring area, recording or recording of the monitoring area is performed. Therefore, when there is a state abnormality in the target person, it is possible to acquire the voice of the target person or a video image of the target person. It becomes possible to immediately recognize the state of the target person, and when there is an intruder in the monitoring area, it is possible to record the appearance and voice of the intruder, so that the intruder can be identified early. it can.

  Further, in order to transmit the sound or recorded video recorded by the microphone 36a and the camera 36b to another notification broadcast receiver 3 and output it, the owner of the other notification broadcast receiver 3 It is possible to clearly recognize what kind of state abnormality has occurred, and to take measures according to the recognized state abnormality at an early stage.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention are arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. be able to. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved. For example, even when it is not possible to accurately determine the presence or absence of a state abnormality in the monitoring area, the problem of the present invention has been solved if the determination of the presence or absence of a state abnormality can be achieved by a technique different from the conventional one. .

(About distribution and integration)
Further, each of the electrical components described above is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution and integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed or integrated in arbitrary units according to various loads or usage conditions. Can be configured. For example, the state abnormality determination unit 18b, the non-output signal number determination unit 18c, the absence state acquisition unit 18d, and the like may be provided in the control unit 39 of the notification broadcast receiver 3 instead of the center device 1.

(About the detector)
In the present embodiment, it has been described that the detection unit 35 is configured by a human sensor, but may be configured by combining a plurality of sensors such as a human sensor and a temperature sensor, for example. In such a case, in the determination process, the state abnormality determination unit 18b may perform the process of SB3 in FIG. 7 based on the detection results of the plurality of sensors.

(About the energy switch)
In the present embodiment, the energy switch 37a is provided in the notification broadcast receiver 3 as a separate switch from the notification reproduction switch 37d, but these may be provided as an integral switch. According to such a configuration, the input means for receiving the input for determining the presence / absence of the state abnormality by outputting the notification broadcast when the input by the energy switch 37a is received, and the input for receiving the instruction to output the notification broadcast Can be used as a single input means. For example, it is possible to determine the presence or absence of an abnormal state of the monitoring area using an existing notification broadcast output switch or the like. It becomes possible to construct a system.

  In the present embodiment, the absence switch 37b is provided in the notification broadcast receiver 3 as a switch separate from the energy switch 37a, but these may be provided as an integral switch. Specifically, the energy switch 37a is input by a third aspect (for example, intermittently operating the energy switch 37a a predetermined number of times at a predetermined interval) different from the first aspect and the second aspect described above. In this case, the energy switch 37a may function as the answering switch 37b. According to such a configuration, the input means for receiving the input for determining the presence / absence of the state abnormality and the input means for receiving the absence state input can be combined with one input means, and at a lower cost. It becomes possible to construct a system.

(About recording and recording means)
In the present embodiment, the recording and recording means has been described as including both the microphone 36a and the camera 36b, but at least one of them may be omitted.

(About input reception processing)
In the present embodiment, if there is no input from the energy switch 37a in the input reception process shown in FIG. 6, it is determined whether a predetermined time has elapsed since the start of the input reception process, and there is no input from the energy switch 37a. If the predetermined time elapses (SA5, Yes), the lighting unit 42 is turned off (SA8). However, the determination process of SA5 may not be performed, and it may wait until there is an input of the energy switch 37a.

(About input promotion means)
In the present embodiment, the input promoting means is the lighting unit 42, but any means may be used as long as it can prompt the subject to input the energy switch 37a. For example, instead of the lighting unit 42, a sound that prompts the subject to input the energy switch 37 a may be output from the speaker 34 of the notification broadcast receiver 3. Moreover, you may prompt the subject to input the energy switch 37a by blinking the lighting part 42.

(About the second aspect)
In the present embodiment, the second mode has been described as a mode in which the energy switch 37a is continuously pressed for a predetermined time or more, but other modes may be used. For example, it is good also as an aspect which repeats the energy switch 37a continuously, or an aspect which inputs 2 times continuously without leaving an interval more than predetermined time.

(About judgment processing)
In the present embodiment, if it is determined in the determination process shown in FIG. 7 that there is no notification broadcast receiver 3 in which the input standby information is stored for a predetermined number of days (SB2, No), the number of sensor detections is predetermined. Although it has been described that the determination whether the number of times is less than the number of times (SB3) is not performed, it may be determined whether the number of times of sensor detection is less than the predetermined number (SB3). Also in this case, when the number of sensor detections is less than the predetermined number (SB3, Yes), the input standby information for a predetermined number of days may be changed to non-input information (SB4). Further, the order of the processing of SB2 and SB3 may be switched. Further, the process of SB3 may be omitted.

(About protectors)
The transmission system 2 may be configured by an electric line. In this case, the notification broadcast receiver 3 may be provided with a protector for controlling a DC component that reaches the receiver on the electric line.

(About judgment criteria)
In the present embodiment, in order to prevent misreporting, it has been described that mail transmission in SB5 in FIG. 7 is executed after referring to input history information for a predetermined number of days. Without referring to the information, if there is no input from the energy switch 37a even after a predetermined time has elapsed from the start of the input receiving process shown in FIG. 6 (SA5, Yes), the mail transmission may be executed immediately.

  In the present embodiment, the determination criteria of each notification broadcast receiver 3 are set uniformly to determine whether there is a state abnormality, but different determination criteria may be set for each notification broadcast receiver 3. For example, in the present embodiment, in the determination process illustrated in FIG. 7, it is determined that the subject has a state abnormality when the number of sensor detections in three days is less than three. However, for example, when the subject is elderly If the subject has illness or the like, it may be determined that the subject has a state abnormality when the number of sensor detections per day is less than three. According to such a configuration, by determining the presence / absence of an abnormal state of the monitoring area based on the determination criteria set for each of the plurality of notification broadcast receivers 3, Detailed information for each notification broadcast receiver 3 such as the home status of the target person can be reflected in the determination of abnormality detection of each notification broadcast receiver 3, so that the accuracy of abnormality detection can be further improved. It becomes possible.

(About crime prevention processing)
In the present embodiment, in the crime prevention process shown in FIG. 9, when the detection unit 35 detects a person's movement when the absence flag is ON (that is, when the center device 1 receives a detection signal) ( SD2, Yes), the control unit 18 of the center device 1 has been described as immediately transmitting a recording / recording signal including the receiver ID of the notification broadcast receiver 3, but the transmission is performed by referring to the input history DB 15a. It may be determined whether or not it should be performed. That is, even when the target person is away, if there is a dynamic object (for example, a pet) other than the target person in the dwelling unit, the pet or the like may be detected by the detection unit 35. Therefore, when the presence of the pet or the like is confirmed, it is preferable to determine whether the detection unit 35 has detected the movement of the pet or the detection unit 35 has detected the movement of the intruder. .

  Therefore, when the control unit 18 of the center apparatus 1 receives the detection signal, the control unit 18 determines whether or not the number of sensor detections for a predetermined number of days in the input history DB 15a is equal to or greater than a predetermined number. As the predetermined number of days and the predetermined number of times, the number of days and the number of times that can be specified when a dynamic object (for example, a pet or the like) other than the target person is detected in the dwelling unit are set. If the number of sensor detections for a predetermined number of days is equal to or greater than the predetermined number of times, it is determined that a pet or the like exists in the dwelling unit. In this case, the center apparatus 1 waits until the detection signal is received for the predetermined number of times or more. When it is determined that a predetermined number of times or more have been received, a recording / recording signal including the receiver ID of the notification broadcast receiver 3 is transmitted. As this predetermined number of times, the number of times that it can be specified that a dynamic object (such as an intruder) other than a pet or the like exists in the dwelling unit is set.

(About the absence flag)
When the center device 1 receives an input signal when the energy switch 37a is input when the absence flag is ON, the user forgets to turn off the absence flag even though the target person is home. Therefore, the control unit 18 of the center device 1 may set the absence flag to OFF.
