However, in Patent Document 1, even when a signal to be transmitted from a terminal (that is, a child device) cannot be received by a transmission / reception terminal device (that is, a receiver) due to an obstacle or the like, warning information (that is, an alarm) is transmitted. There is a possibility that. In other words, even when the presence of the child device is confirmed, an alarm regarding that the child device is not detected may be output as a false alarm. This can reduce the credibility of the alarm.

Therefore, an object of the present invention is to provide an alarm control system and the like that can appropriately control the output of an alarm related to the fact that a slave unit is not detected.

An alarm control system according to an aspect of the present invention performs a first reception process for receiving a signal periodically and wirelessly transmitted from a slave unit, and performs the first reception process according to the signal received in the first reception process. A fixed reception facility for performing a first detection process for detecting a slave unit, the fixed reception facility for fixing a position for receiving the signal, and the radio unit periodically and wirelessly transmitted from the slave unit A mobile receiver that performs a second reception process for receiving a signal and performs a second detection process for detecting the slave unit according to the signal received in the second reception process, wherein the signal is A mobile receiver whose position for receiving is not fixed, and the mobile receiver holds that the mobile device is not detected in a state where the mobile device is not detected by the mobile receiver. Notify and before When the mobile receiver is notified to the mobile receiver that the presence of the slave unit has been confirmed, confirmation information indicating that the slave unit has been confirmed is wirelessly transmitted to the fixed reception facility. The fixed reception facility outputs an alarm regarding that the slave unit is not detected when the confirmation information is received from the mobile receiver in a state where the slave unit is not detected by the fixed reception facility. Is suppressed.

Thereby, the alarm control system can notify the holder of the mobile receiver that the slave unit is not detected in a state where the slave unit is not detected by the mobile receiver. Then, the alarm control system suppresses output of an alarm relating to the fact that the slave unit is not detected when the presence of the slave unit is confirmed by the holder of the mobile receiver in a state where the slave unit is not detected by the fixed reception facility. be able to. Therefore, the alarm control system can appropriately control the output of an alarm related to the fact that the slave unit is not detected.

For example, the mobile receiver wirelessly transmits detection information indicating that the slave unit is detected to the fixed reception facility in a state where the slave unit is detected by the mobile receiver, and the fixed reception facility Further, the alarm output may be suppressed when the detection information is received from the mobile receiver in a state where the slave unit is not detected by the fixed reception facility.

Thereby, the alarm control system can suppress the output of an alarm related to the fact that the slave unit is not detected when the slave unit is detected by the mobile receiver in a state where the slave unit is not detected by the fixed reception facility. Therefore, the alarm control system can appropriately control the output of an alarm related to the fact that the slave unit is not detected.

Further, for example, the fixed reception facility may output the alarm when the output of the alarm is not suppressed in a state where the slave unit is not detected by the fixed reception facility.

This allows the alarm control system to output an alarm when the alarm output is not suppressed. That is, the alarm control system can appropriately output an alarm.

In addition, for example, the fixed reception facility may not detect the slave unit in the fixed reception facility in the first predetermined number of repetitions of the first reception process and the first detection process, and the alarm output is not suppressed. In addition, the alarm may be output.

Thereby, even if the first reception process and the first detection process are repeated for the first predetermined number of times, the alarm control system can output an alarm when the slave unit is not detected. Therefore, the alarm control system can output an alarm at an appropriate timing.

In addition, for example, the mobile receiver may not detect the slave unit when the mobile receiver does not detect the slave unit in the second predetermined number of repetitions of the second reception process and the second detection process. To the holder of the mobile receiver, and the second predetermined number of times may be less than the first predetermined number of times.

As a result, the alarm control system retains the mobile receiver when the slave unit is not detected even if the second reception process and the second detection process are repeated a second predetermined number of times less than the first predetermined number of times. It is possible to notify the person that the handset is not detected. Therefore, the alarm control system can notify at an early timing that the child device is not detected. Therefore, the alarm control system can suppress the alarm output at an early timing.

Also, for example, the fixed reception facility may output the alarm when the slave unit is not detected in the first predetermined period by the fixed reception facility and the output of the alarm is not suppressed.

Thereby, the alarm control system can output an alarm when no slave is detected in the first predetermined period. Therefore, the alarm control system can output an alarm at an appropriate timing.

In addition, for example, the mobile receiver may detect that the mobile device is not detected when the mobile device is not detected by the mobile receiver in a second predetermined period shorter than the first predetermined period. The holder may be notified.

Thereby, the alarm control system can notify the holder of the mobile receiver that the slave unit is not detected when the slave unit is not detected in the second predetermined period shorter than the first predetermined period. Therefore, the alarm control system can notify the holder of the mobile receiver at an early timing that the slave unit is not detected. Therefore, the alarm control system can suppress the alarm output at an early timing.

Further, for example, the fixed reception facility detects the slave unit when the received radio wave intensity of the signal received by the fixed reception facility is greater than a first threshold, and the mobile receiver receives the mobile reception The slave unit may be detected when the received radio wave intensity of the signal received by the machine is larger than a second threshold value.

Thus, the alarm control system can appropriately detect the slave unit by comparing the received radio wave intensity with the threshold value.

Further, for example, the second threshold value may be the same as the first threshold value.

This enables the alarm control system to detect the slave units in the same manner with the fixed reception facility and the mobile receiver.

Further, for example, the second threshold value may be larger than the first threshold value.

This allows the alarm control system to narrow the area where the slave unit is detected by the mobile receiver, compared to the fixed reception facility. Therefore, the alarm control system can notify the holder of the mobile receiver that the slave unit is not detected when it is not detected in a narrower area. Therefore, the alarm control system can notify the holder of the mobile receiver at an early timing that the slave unit is not detected. Further, the alarm control system can prompt the holder of the mobile receiver not to leave the holder of the slave unit.

In addition, for example, the mobile receiver may be configured to detect the second received signal strength of the signal in a state where the mobile device is detected by the mobile receiver than in a state where the mobile device is not detected by the mobile receiver. The threshold may be reduced.

Thereby, the alarm control system can suppress frequent notification to the holder of the mobile receiver when the received radio wave intensity changes near the threshold.

Also, for example, the mobile receiver indicates that the presence of the slave unit is not confirmed when the mobile receiver is notified that the presence of the slave unit is not confirmed to the mobile receiver. Non-confirmation information is wirelessly transmitted to the fixed reception facility, and the fixed reception facility receives the non-confirmation information from the mobile receiver in a state where the slave unit is detected by the fixed reception facility. A warning regarding the absence of the presence of the slave unit may be output.

Thereby, the alarm control system can output a warning when the holder of the mobile receiver leaves the holder of the slave unit. That is, the alarm control system can notify that the holder of the mobile receiver is away from the holder of the slave unit.

Further, for example, the alarm control system may include each of a plurality of mobile receivers including a first mobile receiver and a second mobile receiver as the mobile receiver.

This allows the alarm control system to control the alarm output using a plurality of mobile receivers.

In addition, for example, the first mobile receiver performs a process of notifying the holder of the first mobile receiver that the slave unit is not detected in a state where the slave unit is not detected by the first mobile receiver. , Only the first slave unit among the first slave unit and the second slave unit as the slave unit, the second mobile receiver is in a state where the slave unit is not detected by the second mobile receiver, The process of notifying the holder of the second mobile receiver that no child device is detected may be performed only for the second child device among the first child device and the second child device as the child device. .

Thereby, the alarm control system can notify the holder of the mobile receiver that the slave unit associated with the mobile receiver is not detected.

For example, the first mobile receiver wirelessly transmits detection information indicating that the slave unit is detected to the fixed reception facility in a state where the slave unit is detected by the first mobile receiver. The processing is performed only for the first slave unit among the first slave unit and the second slave unit as the slave unit, and the second mobile receiver detects the slave unit by the second mobile receiver. In the state, the process of wirelessly transmitting the detection information indicating that the slave unit is detected to the fixed reception facility is the second slave unit among the first slave unit and the second slave unit. When the detection information is received from the first mobile receiver or the second mobile receiver in a state where the fixed receiver is not detected by the fixed receiver. , Suppress the output of the alarm The management may be performed for each of the first daughter machine and the second subsidiary unit as the slave unit.

Thus, the alarm control system can appropriately control the alarm output related to the fact that the slave unit is not detected by the fixed reception facility by the detection by the mobile receiver corresponding to the slave unit.

For example, the first mobile receiver wirelessly transmits detection information indicating that the slave unit is detected to the fixed reception facility in a state where the slave unit is detected by the first mobile receiver. Processing is performed for each of the first slave unit and the second slave unit as the slave unit, and the second mobile receiver is in a state in which the slave unit is detected by the second mobile receiver.

As a result, the alarm control system can appropriately control the output of an alarm related to the fact that each of the first slave unit and the second slave unit is not detected by detection at the first mobile receiver and the second mobile receiver. .

In addition, for example, the first mobile receiver performs a process of notifying the holder of the first mobile receiver that the slave unit is not detected in a state where the slave unit is not detected by the first mobile receiver. , The first mobile receiver and the second mobile receiver perform the same slave unit, and the second mobile receiver is in a state where the slave unit is not detected by the second mobile receiver. The process of notifying the holder of the second mobile receiver that no mobile device is detected may be performed on the slave device common to the first mobile receiver and the second mobile receiver.

Thereby, the alarm control system can notify the respective holders of the first mobile receiver and the second mobile receiver that the slave unit is not detected.

For example, the first mobile receiver wirelessly transmits detection information indicating that the slave unit is detected to the fixed reception facility in a state where the slave unit is detected by the first mobile receiver. A state where the first mobile receiver and the second mobile receiver share the slave unit, and the second mobile receiver is in a state in which the slave unit is detected by the second mobile receiver The first mobile receiver and the second mobile receiver perform the process of wirelessly transmitting the detection information indicating that the slave is detected to the fixed reception facility.

In addition, the management apparatus 130 performs output processing such as an alarm in the fixed reception facility 140. For example, if the management apparatus 130 receives confirmation information indicating that the slave unit 110 has been confirmed in a state where the slave unit 110 is not detected by the fixed reception facility 140, the management apparatus 130 outputs an alarm regarding that the slave unit 110 is not detected. Deter. On the other hand, the management apparatus 130 outputs an alarm when the alarm output is not suppressed in a state where the slave unit 110 is not detected.

For example, the management device 130 may be an information processing device. The management device 130 can also be expressed as a parent device for the child device 110. A personal computer, a smartphone, a mobile phone, or the like may be used for the management device 130. Moreover, the management apparatus 130 may be arrange | positioned in a fixed position and does not need to be arrange | positioned in a fixed position. That is, the management device 130 may move. For example, the management device 130 may be held by a person or moved by the movement of the person.

FIG. 2 shows an example of the fixed reception facility 140, but the fixed reception facility 140 is not limited to the example of FIG. The fixed reception facility 140 may be one fixed receiver 120 that also serves as the management device 130.

FIG. 3 is a schematic diagram showing the arrangement of each component of the alarm control system 100 shown in FIG. In this example, a plurality of fixed receivers 120 and a management device 130 constituting the fixed reception facility 140 are shown as the fixed reception facility 140 shown in FIG.

3, a plurality of circles hatched with diagonal lines indicate a plurality of slave units 110, a plurality of double circles indicate a plurality of fixed receivers 120, and a plurality of triangles indicate a plurality of mobile receivers 150. The plurality of fixed receivers 120 are fixedly installed in the area 200. The plurality of slave units 110 basically exist inside the area 200. However, each handset 110 moves. And the subunit | mobile_unit 110 may move to the exterior of the area 200. FIG.

The management device 130 may be installed inside the area 200 or may be installed outside the area 200. In addition, the management device 130 may be held by a person, and may move regardless of whether the person holding the management device 130 moves inside or outside the area 200.

The area 200 may be an indoor area or an outdoor area. The area 200 may include an indoor area and an outdoor area. The plurality of slave units 110 are expected to exist in the area 200.

For example, the area 200 is a campsite, a park, a plaza or a large-scale facility. In area 200, a plurality of children gather. If a child leaves the area 200, the child may be missing. Therefore, the plurality of slave units 110 are attached to a plurality of children gathering in the area 200, respectively. And the alarm control system 100 detects the subunit | mobile_unit 110 which exists in the area 200 by receiving a signal with the fixed receiving equipment 140 containing the some fixed receiver 120. FIG. Thereby, it can be estimated whether a child exists in the area 200 or not.

On the other hand, when the child becomes lean so as to cover the child device 110, the child device 110 enters the blind spot of the fixed receiver 120, or the radio wave is blocked by a large number of dense children, the signal is sufficient. There is a possibility that it will not be received with the radio wave reception strength. In such a case, there is a possibility that the slave unit 110 is not detected by the fixed reception facility 140 even though the slave unit 110 exists in the area 200. And there is a possibility that an alarm relating to the fact that the slave unit 110 is not detected is output as a false alarm.

In order to suppress such false alarms, the mobile receiver 150 moves when the mobile receiver 150 does not detect the slave 110 when the mobile receiver 150 does not receive the signal of the slave 110 with sufficient radio wave reception intensity. Notify the holder of the receiver 150. And the presence or absence of the subunit | mobile_unit 110 is confirmed by the holder. When the existence of the child device 110 is confirmed, the holder is notified to the mobile receiver 150 that the existence of the child device 110 has been confirmed.

When the mobile receiver 150 is notified by the holder to the mobile receiver 150 that the presence of the slave unit 110 has been confirmed, the mobile receiver 150 receives confirmation information indicating that the slave unit 110 has been confirmed. 140. When the fixed reception facility 140 receives the confirmation information from the mobile receiver 150, the fixed reception facility 140 suppresses the alarm output. Thereby, it is suppressed that the alarm regarding that the subunit | mobile_unit 110 is not detected is output as a misreport.

For example, the holder of the mobile receiver 150 is an instructor, a supervisor, a guardian, or an instructor of a child to which the slave unit 110 is attached. In addition, the holder of the mobile receiver 150 may be an instructor, a supervisor, a guardian, or an instructor of a plurality of children each equipped with a plurality of slave units 110.

As a specific example, in the area 200, a plurality of children act for each group. In one group, about 1 to 3 instructors lead about 30 children in the area 200. Each child is equipped with a child device 110. Each instructor holds the mobile receiver 150.

And the some mobile receiver 150 and the some subunit | mobile_unit 110 are matched for every group. The mobile receiver 150 notifies the holder of the mobile receiver 150 that the slave unit 110 is not detected in a state where the slave unit 110 associated with the mobile receiver 150 is not detected. That is, the mobile receiver 150 notifies the instructor holding the mobile receiver 150 that the child device 110 attached to the child led by the instructor is not detected.

Then, the instructor who is notified that the child device 110 is not detected confirms the presence or absence of the child device 110 by visually confirming the presence or absence of the child wearing the child device 110. Then, when the presence of the handset 110 is confirmed, the instructor notifies the mobile receiver 150 that the presence of the handset 110 has been confirmed. Thereby, it is suppressed that the alarm regarding that the subunit | mobile_unit 110 is not detected is output as a misreport.

Further, for example, even if the slave unit 110 and the mobile receiver 150 are separated from the area 200, if the slave unit 110 exists near the mobile receiver 150, the presence of the slave unit 110 indicates that the mobile receiver 150 It can be confirmed by the holder. That is, even if the child and the instructor are away from the area 200, the output of the alarm can be suppressed if the child exists near the instructor. Therefore, the alarm control system 100 can appropriately suppress alarm output even when the slave unit 110 and the mobile receiver 150 are away from the area 200.

FIG. 4 is a graph showing the received radio wave intensity of the signal received by the fixed reception facility 140 shown in FIG. For example, the signal received by the fixed reception facility 140 is a signal received by the fixed receiver 120 that constitutes the fixed reception facility 140.

For example, the fixed receiver 120 receives a signal from the slave unit 110 each time. Therefore, when the signal transmitted from the slave unit 110 reaches the fixed receiver 120, the fixed receiver 120 periodically transmits the signal from the slave unit 110 at the transmission interval of the signal periodically transmitted by the slave unit 110. Receive. The received radio wave intensity of the signal received by fixed receiver 120 varies depending on the distance between fixed receiver 120 and slave unit 110.

For example, when the fixed receiver 120 receives a signal transmitted from the slave unit 110, the fixed receiver 120 measures the received radio wave intensity of the received signal. The management device 130 obtains signal information indicating the slave unit 110 indicated by the signal and the received radio wave intensity of the signal from the fixed receiver 120, and if the received radio wave intensity of the signal is greater than the threshold, The slave unit 110 shown is detected.

Alternatively, the fixed receiver 120 detects the slave unit 110 indicated by the signal when the received radio wave intensity of the signal is larger than the threshold, and transmits detection information indicating the detected slave unit 110 to the management device 130. Also good. Then, the management apparatus 130 may detect the slave unit 110 indicated by the detection information according to the detection information transmitted from the fixed receiver 120.

According to the above-described operation, the fixed reception facility 140 receives a signal transmitted from the slave unit 110, and is transmitted from the slave unit 110 when the received radio wave intensity of the signal transmitted from the slave unit 110 is larger than a threshold value. The slave unit 110 indicated by the received signal is detected. For example, the fixed reception facility 140 detects the slave unit 110 indicated by the signal when any one of the plurality of fixed receivers 120 receives a signal whose received radio wave intensity is greater than a threshold value.

On the other hand, the fixed reception facility 140 does not detect the slave unit 110 when the received radio wave intensity of the signal transmitted from the slave unit 110 is not greater than the threshold value. Here, the case where the received radio wave intensity of the signal is not larger than the threshold value includes the case where the signal does not reach the fixed reception facility 140. The threshold may be 0. That is, when the fixed reception facility 140 receives a signal, the fixed reception facility 140 may detect the slave unit 110 indicated by the signal regardless of the received radio wave intensity.

In the example of FIG. 4, the fixed reception facility 140 receives a signal from the slave unit 110 seven times. The received radio wave intensity of the signals received from the first time to the fourth time is larger than the threshold value. Therefore, the slave unit 110 is in the detection state in the first to fourth signal reception. The received radio wave intensity of signals received from the fifth time to the seventh time is not greater than the threshold value. Therefore, the slave unit 110 is in a non-detection state in receiving signals from the fifth time to the seventh time.

FIG. 5 is a graph showing the received radio wave intensity of the signal received by the mobile receiver 150 shown in FIG. Similarly to the fixed reception facility 140, the mobile receiver 150 also receives a signal and detects the slave unit 110 according to the received signal.

For example, like the fixed receiver 120, the mobile receiver 150 receives a signal from the slave unit 110 each time. Therefore, when the signal transmitted from the slave unit 110 reaches the mobile receiver 150, the mobile receiver 150 periodically transmits the signal from the slave unit 110 at the transmission interval of the signal periodically transmitted by the slave unit 110. Receive. The received radio wave intensity of the signal received by the mobile receiver 150 varies depending on the distance between the mobile receiver 150 and the slave unit 110.

For example, when the mobile receiver 150 receives a signal transmitted from the slave unit 110, the mobile receiver 150 measures the received radio wave intensity of the received signal. Then, the mobile receiver 150 detects the slave unit 110 indicated by the signal when the received radio wave intensity of the signal is larger than the threshold value.

On the other hand, the mobile receiver 150 does not detect the slave unit 110 when the received radio wave intensity of the signal transmitted from the slave unit 110 is not greater than the threshold value. Here, the case where the received radio wave intensity of the signal is not larger than the threshold value includes the case where the signal does not reach the mobile receiver 150. The threshold may be 0. That is, when the mobile receiver 150 receives a signal, the mobile receiver 150 may detect the slave unit 110 indicated by the signal regardless of the received radio wave intensity.

In the example of FIG. 5, the mobile receiver 150 receives the signal from the slave unit 110 seven times as in the example of the fixed reception facility 140 of FIG. 4. The received radio wave intensity of the signals received from the first time to the fourth time is larger than the threshold value. Therefore, the slave unit 110 is in the detection state in the first to fourth signal reception. The received radio wave intensity of signals received from the fifth time to the seventh time is not greater than the threshold value. Therefore, the slave unit 110 is in a non-detection state in receiving signals from the fifth time to the seventh time.

The distance between the slave unit 110 and the fixed reception facility 140, more specifically, the distance between the slave unit 110 and the fixed receiver 120 is sufficiently close, and the distance between the slave unit 110 and the mobile receiver 150 is sufficiently close. In this case, the fixed reception facility 140 and the mobile receiver 150 receive signals in the same way. And the fixed receiving equipment 140 and the mobile receiver 150 detect the subunit | mobile_unit 110 similarly.

And, for example, when a child holding the handset 110 is covered with the handset 110, the received radio wave intensity of the signal is reduced in both the fixed reception facility 140 and the mobile receiver 150. Then, the slave unit 110 is not detected in both the fixed reception facility 140 and the mobile receiver 150.

In a state where the mobile device 150 is not detected by the mobile receiver 150, the mobile receiver 150 notifies the holder of the mobile receiver 150 that the mobile device 110 is not detected. And the presence or absence of the subunit | mobile_unit 110 is confirmed by the holder of the mobile receiver 150. FIG. When the mobile receiver 150 notifies the mobile receiver 150 that the presence of the slave unit 110 has been confirmed, the mobile receiver 150 provides confirmation information indicating that the presence of the slave unit 110 has been confirmed. Transmit to the fixed reception facility 140.

The fixed reception facility 140 suppresses alarm output when confirmation information is received from the mobile receiver 150 in a state where the slave unit 110 is not detected in the fixed reception facility 140. The fixed reception facility 140 outputs an alarm when the alarm output is not suppressed.

For example, the mobile receiver 150 notifies the holder of the mobile receiver 150 that the slave unit 110 is not detected in the first reception (for example, the fifth reception in FIG. 5) in which the slave unit 110 is not detected. Also good. Then, the fixed reception facility 140 outputs an alarm if confirmation information is not received from the mobile receiver 150 by the third reception (for example, the seventh reception in FIG. 4) when the slave unit 110 is not detected. Also good.

That is, the number of times the reception process and the detection process in which the slave unit 110 is not detected by the mobile receiver 150 until the notification is repeated is larger than the number of times the reception process and the detection process in which the slave unit 110 is not detected by the fixed reception facility 140 is repeated until the alarm. It may be less. Thereby, the alarm control system 100 can output an alarm after a grace period for confirmation elapses.

In the above example, the reception process and the detection process in which the slave unit 110 is not detected by the mobile receiver 150 are repeated until the notification, and the reception process and the detection process in which the slave unit 110 is not detected by the fixed reception facility 140 are performed. The number of times that an alarm is repeated is three. However, the number of times is not limited to the above example, and may be adjusted as appropriate.

In the above example, the notification and alarm are controlled by the number of reception processes and detection processes, but the notification and alarm may be controlled by time. For example, the time from when the mobile device 150 is no longer detected by the mobile receiver 150 to the notification may be shorter than the time from when the mobile device 110 is no longer detected by the fixed reception facility 140 to the alarm. Thereby, the alarm control system 100 can output an alarm after a grace period for confirmation elapses.

In addition, after an alarm regarding that the slave unit 110 is not detected is output, the holder of the mobile receiver 150 confirms the presence of the slave unit 110 and confirms that the slave unit 110 has been confirmed. May be notified. Then, the mobile receiver 150 may transmit confirmation information indicating that the presence of the slave unit 110 has been confirmed to the fixed reception facility 140. And the fixed reception equipment 140 may suppress the output of the alarm by receiving the confirmation information and stopping the output of the alarm according to the confirmation information.

In addition, for example, the threshold for detecting the slave unit 110 by the fixed reception facility 140 and the threshold for detecting the slave unit 110 by the mobile receiver 150 may be the same or different. . That is, the threshold value shown in FIG. 4 and the threshold value shown in FIG. 5 may be the same or different. The threshold for the mobile receiver 150 to detect the slave unit 110 may be larger than the threshold for the fixed reception facility 140 to detect the slave unit 110 so that notification is performed earlier.

Further, the mobile receiver 150 may perform a hysteresis process in the comparison between the received radio wave intensity and the threshold value in order to suppress chattering.

Specifically, when the slave unit 110 is in the detection state, the mobile receiver 150 may relatively reduce the threshold value for the received radio wave intensity of the signal received from the slave unit 110. Further, when the handset 110 is in a non-detection state, the mobile receiver 150 may relatively increase the threshold value for the received radio wave intensity of the signal received from the handset 110. Alternatively, the mobile receiver 150 may maintain the state of the mobile receiver 150 regardless of the received radio wave intensity for a certain period or longer after the state of the slave unit 110 changes. Thereby, frequent notification is suppressed.

In the hysteresis processing, the mobile receiver 150 may change the threshold value in the mobile receiver 150 in a range larger than the threshold value in the fixed reception facility 140, or the mobile receiver 150 in a range that is equal to or larger than the threshold value in the fixed reception facility 140. The threshold at 150 may be changed. Alternatively, the mobile receiver 150 may change the threshold value in the mobile receiver 150 regardless of the threshold value in the fixed reception facility 140. For example, the mobile receiver 150 may reduce the threshold by about 10% in the detection state compared to the non-detection state.

Also, the fixed reception facility 140 may perform hysteresis processing in the same manner as the mobile receiver 150. For example, the fixed reception facility 140 may change the threshold value in the fixed reception facility 140 in a range smaller than the threshold value in the mobile receiver 150, or may be changed in the fixed reception facility 140 within a range equal to or less than the threshold value in the mobile receiver 150. The threshold value may be changed. Alternatively, the fixed reception facility 140 may change the threshold value in the fixed reception facility 140 regardless of the threshold value in the mobile receiver 150.

FIG. 6 is a schematic diagram showing a detection area of the fixed receiver 120 shown in FIG. A circle indicated by a dotted line in FIG. 6 indicates each detection area of the plurality of fixed receivers 120.

The detection area of the fixed receiver 120 is an area in which the slave unit 110 can be detected according to the signal received by the fixed receiver 120 from the slave unit 110. That is, the fixed reception facility 140 can detect the slave unit 110 according to a signal received by the fixed receiver 120 from the slave unit 110 existing in the detection area of the fixed receiver 120. The size of the detection area can be adjusted by adjusting the threshold for the received radio wave intensity.

For example, each fixed receiver 120 is installed so that the plurality of detection areas of the plurality of fixed receivers 120 cover the area 200, and the size of each detection area is adjusted. Each fixed receiver 120 may be installed and the size of each detection area may be adjusted so that a plurality of detection areas completely cover the area 200 without blanks.

That is, the mobile receiver 150 can detect the slave unit 110 according to the signal received from the slave unit 110 existing in the detection area of the mobile receiver 150. The size of the detection area can be adjusted by adjusting the threshold for the received radio wave intensity.

For example, an instructor who leads multiple children moves with the multiple children being led. Therefore, the mobile receiver 150 held by the instructor moves together with the plurality of slave units 110 that are respectively attached to the plurality of children led. And it is expected that there are a plurality of child devices 110 respectively attached to a plurality of children led in the detection area of the mobile receiver 150 held by the instructor. The size of the detection area of the mobile receiver 150 held by the instructor may be adjusted to the range of the area that can be confirmed by the instructor by adjusting the threshold value.

On the other hand, the information processing unit 132 outputs an alarm via the output unit 133 when the alarm output is not suppressed in the state where the slave unit 110 is not detected by the information processing unit 132.

FIG. 12 is a sequence diagram showing a first operation pattern of the alarm control system 100 shown in FIG.

For example, the slave unit 110 transmits a signal. Then, the mobile receiver 150 receives the signal transmitted from the slave unit 110 and detects the slave unit 110. The fixed reception facility 140 also receives the signal transmitted from the slave unit 110 and detects the slave unit 110. That is, the signal is received by both the mobile receiver 150 and the fixed reception facility 140, and the slave unit 110 is detected (S111).

In this case, the alarm control system 100 does not output an alarm or the like. For example, in this case, it is assumed that the handset 110 exists in the area 200 near the mobile receiver 150. Specifically, for example, it is assumed that a child wearing the child device 110 is present in the area 200 near an instructor holding the mobile receiver 150. Therefore, in this case, an output such as an alarm is unnecessary.

In this case, the mobile receiver 150 may transmit detection information indicating that the mobile device 110 is detected by the mobile receiver 150 to the fixed reception facility 140.

FIG. 13 is a sequence diagram showing a second operation pattern of the alarm control system 100 shown in FIG.

As in the example of FIG. 12, the slave unit 110 transmits a signal. In this example, the signal transmitted from the slave unit 110 does not reach the mobile receiver 150 and is not received by the mobile receiver 150. Alternatively, the mobile receiver 150 does not receive a signal with a received radio wave intensity greater than the threshold value. Similarly, the signal transmitted from the slave unit 110 does not reach the fixed receiver 120 of the fixed reception facility 140 and is not received by the fixed reception facility 140. Alternatively, the fixed reception facility 140 does not receive a signal with a received radio wave intensity greater than the threshold value.

Therefore, the slave unit 110 is not detected in both the mobile receiver 150 and the fixed reception facility 140 (S121). In this case, the mobile receiver 150 notifies the holder of the mobile receiver 150 that the mobile device 150 is not detected by the mobile receiver 150 (S122). And the presence or absence of the subunit | mobile_unit 110 is confirmed by the holder of the mobile receiver 150. FIG. In this example, the presence of the slave unit 110 is not confirmed by the holder of the mobile receiver 150. That is, it is confirmed by the holder of the mobile receiver 150 that the slave unit 110 does not exist.

Therefore, in this example, confirmation information indicating that the presence of the slave unit 110 has been confirmed is not transmitted to the fixed reception facility 140, and the output of an alarm regarding that the slave unit 110 is not detected is not suppressed. Therefore, the fixed reception facility 140 outputs an alarm (S123). For example, in this case, it is assumed that it is difficult to confirm the presence of a child wearing the handset 110 in the area 200. Then, there is a possibility that the child is outside the area 200.

The alarm control system 100 can appropriately prompt a larger search by outputting an alarm in the above case.

In this example, the holder of the mobile receiver 150 may notify the mobile receiver 150 that the presence of the slave unit 110 is not confirmed by the holder of the mobile receiver 150. Here, the notification that the presence of the child device 110 is not confirmed can also be expressed as a non-confirmation notification. Then, the mobile receiver 150 may transmit non-confirmation information indicating that the presence of the slave unit 110 is not confirmed to the fixed reception facility 140 according to the notification. And the fixed reception equipment 140 may output an alarm immediately when non-confirmation information is received.

In addition, when a plurality of mobile receivers 150 are associated with the slave unit 110, the fixed reception facility 140 receives the non-confirmation information from each of all the mobile receivers 150 associated with the slave unit 110. An alarm may be output.

For example, at least one of the plurality of mobile receivers 150 associated with the slave unit 110 detects the slave unit 110 and transmits detection information indicating that the slave unit 110 is detected to the fixed reception facility 140. Then, the output of the alarm can be suppressed as shown in FIG.

FIG. 14 is a sequence diagram showing a third operation pattern of the alarm control system 100 shown in FIG.

As in the example of FIG. 12, the slave unit 110 transmits a signal. Similarly to the example of FIG. 13, the signal transmitted from the slave unit 110 does not reach the mobile receiver 150 and is not received by the mobile receiver 150. Alternatively, the mobile receiver 150 does not receive a signal with a received radio wave intensity greater than the threshold value. Similarly, the signal transmitted from the slave unit 110 does not reach the fixed receiver 120 of the fixed reception facility 140 and is not received by the fixed reception facility 140. Alternatively, the fixed reception facility 140 does not receive a signal with a received radio wave intensity greater than the threshold value.

Therefore, the slave unit 110 is not detected in both the mobile receiver 150 and the fixed reception facility 140 (S131). In this case, the mobile receiver 150 notifies the holder of the mobile receiver 150 that the mobile device 150 is not detected by the mobile receiver 150. And the presence or absence of the subunit | mobile_unit 110 is confirmed by the holder of the mobile receiver 150. FIG. In this example, the holder of the mobile receiver 150 confirms the presence of the slave unit 110, and the holder of the mobile receiver 150 notifies the mobile receiver 150 that the presence of the slave unit 110 has been confirmed ( S132).

Then, the mobile receiver 150 transmits confirmation information indicating that the presence of the slave unit 110 has been confirmed to the fixed reception facility 140. The fixed reception facility 140 receives the confirmation information and suppresses the output of an alarm related to the slave unit 110 not being detected (S133). Therefore, the fixed reception facility 140 does not output an alarm.

For example, in this case, the instructor has confirmed the presence of the child wearing the handset 110 in the area 200. In such a case, it is not appropriate to output an alarm. The alarm control system 100 can suppress an alarm from being output as a false alarm in such a case.

Note that, for example, if at least one of the plurality of mobile receivers 150 associated with the slave unit 110 transmits the confirmation information to the fixed reception facility 140, the output of the alarm can be suppressed. Then, information indicating that the presence of the child device 110 has been confirmed may be transmitted to the mobile receiver 150 of the holder whose existence is not confirmed, and the information may be notified to the holder.

FIG. 15 is a sequence diagram showing a fourth operation pattern of the alarm control system 100 shown in FIG.

As in the example of FIG. 12, the slave unit 110 transmits a signal. In this example, the mobile receiver 150 receives a signal transmitted from the slave unit 110 and detects the slave unit 110. On the other hand, the signal transmitted from the slave unit 110 does not reach the fixed receiver 120 of the fixed reception facility 140 and is not received by the fixed reception facility 140. Alternatively, the fixed reception facility 140 does not receive a signal with a received radio wave intensity greater than the threshold value. Accordingly, the slave unit 110 is detected by the mobile receiver 150, but the slave unit 110 is not detected by the fixed reception facility 140 (S141).

In this case, the mobile receiver 150 transmits detection information indicating that the mobile device 110 is detected by the mobile receiver 150 to the fixed reception facility 140. The fixed reception facility 140 receives the detection information and suppresses the output of an alarm related to the fact that the handset 110 is not detected (S142). Therefore, the fixed reception facility 140 does not output an alarm.

For example, in this case, the slave unit 110 is detected by the mobile receiver 150 in the area 200. That is, in area 200, it is assumed that the child wearing child device 110 is present near the instructor. In such a case, it is not appropriate to output an alarm. The alarm control system 100 can suppress an alarm from being output as a false alarm in such a case.

For example, if at least one of the plurality of mobile receivers 150 associated with the slave unit 110 detects the slave unit 110 and transmits detection information indicating that the slave unit 110 is detected to the fixed reception facility 140. The alarm output can be suppressed.

Further, in this case, information indicating that the slave unit 110 is detected for the mobile receiver 150 in which the slave unit 110 is not detected among the plurality of mobile receivers 150 associated with the slave unit 110. May be transmitted and a warning may be notified to the holder. For example, this warning indicates that the slave unit 110 is detected by another mobile receiver 150.

FIG. 16 is a sequence diagram showing a fifth operation pattern of the alarm control system 100 shown in FIG.

As in the example of FIG. 12, the slave unit 110 transmits a signal. In this example, the signal transmitted from the slave unit 110 does not reach the mobile receiver 150 and is not received by the mobile receiver 150. Alternatively, the mobile receiver 150 does not receive a signal with a received radio wave intensity greater than the threshold value. On the other hand, the fixed reception facility 140 receives a signal transmitted from the slave unit 110 and detects the slave unit 110. Accordingly, the slave unit 110 is not detected by the mobile receiver 150, but the slave unit 110 is detected by the fixed reception facility 140 (S151).

In this case, the mobile receiver 150 notifies the holder of the mobile receiver 150 that the mobile receiver 150 is not detected by the mobile receiver 150. And the presence or absence of the subunit | mobile_unit 110 is confirmed by the holder of the mobile receiver 150. FIG. In this example, the presence of the slave unit 110 is not confirmed by the holder of the mobile receiver 150. That is, it is confirmed by the holder of the mobile receiver 150 that the slave unit 110 does not exist. Furthermore, in this example, the holder of the mobile receiver 150 notifies the mobile receiver 150 that the presence of the slave unit 110 is not confirmed (S152).

Then, the mobile receiver 150 transmits non-confirmation information indicating that the presence of the slave unit 110 is not confirmed to the fixed reception facility 140. The fixed reception facility 140 receives the non-confirmation information and outputs a warning regarding the absence of the presence of the slave unit 110 (S153).

For example, in this case, the slave unit 110 is detected by the fixed reception facility 140. That is, it is assumed that a child wearing the child device 110 exists in the area 200. On the other hand, the mobile device 150 is not detected by the mobile receiver 150, and the presence of the mobile device 110 is not confirmed by the holder of the mobile receiver 150. That is, it is assumed that the child wearing the handset 110 does not exist near the instructor. The alarm control system 100 can prompt the search in the area 200 appropriately by outputting a warning in such a case.

For example, when detection information or confirmation information of the slave unit 110 is transmitted from another mobile receiver 150, information indicating that the slave unit 110 is detected or confirmed to the mobile receiver 150 May be notified, and the information may be notified to the holder. In this case, the warning need not be output.

In addition, when the mobile receiver 150 does not detect the mobile device 110 (S151), the mobile receiver 150 determines whether the mobile device 110 is connected to the mobile receiver 150 regardless of the non-detection notification and non-confirmation notification processing (S152). Non-detection information indicating that it is not detected may be transmitted. Then, the fixed reception facility 140, when the slave unit 110 is detected by the fixed reception facility 140 and non-detection information is received from the mobile receiver 150, warns regardless of the non-confirmation information processing (S153). It may be output.

As described above, when the slave unit 110 is detected by the fixed receiver facility 140 and the non-detection information is received from the mobile receiver 150, the fixed receiver facility 140 confirms the slave unit 110 by the holder of the mobile receiver 150. A warning may be output after a grace time for the elapse.

The alarm control system 100 may not operate according to all of the plurality of operation patterns shown in FIGS. For example, the alarm control system 100 may operate according to one or more operation patterns arbitrarily selected from a plurality of operation patterns shown in FIGS. Specifically, for example, the alarm control system 100 may operate according to the three operation patterns shown in FIGS.

Also, the mobile receiver 150 may notify the holder of the mobile receiver 150 that the slave unit 110 is not detected in a state where the slave unit 110 associated with the mobile receiver 150 is not detected. And when the subunit | mobile_unit 110 is matched with the some mobile receiver 150, the subunit | mobile_unit 110 is not detected to each holder of the some mobile receiver 150 with which the subunit | mobile_unit 110 is matched. May be notified.

FIG. 17 is a flowchart showing the operation of the slave unit 110 shown in FIG. Specifically, the transmitting unit 111 constituting the slave unit 110 shown in FIG. 8 may perform the operation shown in FIG.

For example, the transmitter 111 periodically and wirelessly transmits a signal indicating the slave unit 110 (S201). Specifically, transmission section 111 periodically transmits a signal indicating slave unit 110 wirelessly at 5 seconds, 10 seconds, or other transmission intervals. The transmission interval is basically constant, but may vary.

FIG. 18 is a flowchart showing the operation of the fixed reception facility 140 shown in FIG. Specifically, the plurality of fixed receivers 120 and the management device 130 constituting the fixed reception facility 140 shown in FIG. 2 may perform the operation shown in FIG. More specifically, the reception unit 121, the information processing unit 122, and the transmission unit 123 that configure the fixed receiver 120 illustrated in FIG. 9, and the reception unit 131 that configures the management device 130 illustrated in FIG. The information processing unit 132 and the output unit 133 may perform the operation illustrated in FIG.

For example, the fixed reception facility 140 performs a reception process for receiving a signal transmitted from the slave unit 110 (S301). And the fixed reception equipment 140 performs the detection process for detecting the subunit | mobile_unit 110 according to the received signal (S302). And the fixed reception equipment 140 determines whether the subunit | mobile_unit 110 is a detection state or a non-detection state (S303).

Specifically, in the fixed reception facility 140, the reception unit 121 of the fixed receiver 120 performs a reception process for receiving a signal transmitted from the slave unit 110. Then, the information processing unit 122 of the fixed receiver 120 transmits the received signal strength of the signal and the signal information indicating the slave device 110 of the signal transmission source to the management apparatus 130 via the transmission unit 123 of the fixed receiver 120. To do.

Then, in the fixed reception facility 140, the reception unit 131 of the management device 130 receives the signal information. And the information processing part 132 of the management apparatus 130 performs a detection process by determining whether the received radio wave intensity | strength of a signal is larger than a threshold value according to signal information.

And the information processing part 132 detects the subunit | mobile_unit 110 of the transmission origin of a signal, when the received radio wave strength of a signal is larger than a threshold value. That is, the information processing unit 132 determines that the child device 110 is in a detection state. When the received radio wave intensity of the signal is not greater than the threshold value, the information processing unit 132 does not detect the slave unit 110 that is the source of the signal. The information processing unit 132 determines that the child device 110 is in a non-detected state.

As described above, when the received radio wave intensity of the signal is not larger than the threshold value, the case where the signal does not reach the fixed reception facility 140 is included. That is, the information processing unit 132 determines that the slave unit 110 is in a non-detection state when the reception unit 131 does not receive a signal from the slave unit 110 at the transmission interval.

In the non-detection state (No in S303), the fixed reception facility 140 determines whether or not detection information indicating that the mobile device 110 has been detected by the mobile receiver 150 has been received (S304).

For example, when the detection information is transmitted from the mobile receiver 150, the reception unit 131 of the management apparatus 130 detects the detection information from the mobile receiver 150 via the fixed receiver 120 or not via the fixed receiver 120. Receive. Then, the information processing unit 132 of the management device 130 determines whether or not the detection information is received in a state where the slave device 110 is not detected by the management device 130.

In the non-detection state (No in S303), the fixed reception facility 140 determines whether confirmation information indicating that the presence of the slave unit 110 has been received from the mobile receiver 150 (S305).

For example, when the confirmation information is transmitted from the mobile receiver 150, the reception unit 131 of the management apparatus 130 confirms the confirmation information from the mobile receiver 150 via the fixed receiver 120 or not via the fixed receiver 120. Receive. Then, the information processing unit 132 of the management device 130 determines whether confirmation information has been received in a state where the slave device 110 is not detected by the management device 130.

And in a non-detection state (No in S303), when neither detection information nor confirmation information is received (No in S304 and No in S305), the fixed reception facility 140 issues an alarm regarding that the slave unit 110 is not detected. Output (S306). In other words, in this case, the information processing unit 132 of the management apparatus 130 outputs an alarm regarding that the slave unit 110 is not detected via the output unit 133 of the management apparatus 130.

Then, in the non-detection state (No in S303), when detection information or confirmation information is received (Yes in S304 or Yes in S305), the fixed reception facility 140 suppresses the output of an alarm (S304). That is, in this case, the information processing unit 132 of the management device 130 suppresses the output of the alarm.

On the other hand, in the detection state (Yes in S303), the fixed reception facility 140 determines whether or not unconfirmed information indicating that the presence of the slave unit 110 is not confirmed has been received from the mobile receiver 150 (S308).

For example, when non-confirmation information is transmitted from the mobile receiver 150, the receiving unit 131 of the management apparatus 130 receives non-confirmation from the mobile receiver 150 via the fixed receiver 120 or without using the fixed receiver 120. Receive confirmation information. Then, the information processing unit 132 of the management device 130 determines whether or not unconfirmed information has been received in a state where the slave device 110 is detected by the management device 130.

When the non-confirmation information is received in the detection state (Yes in S303) (Yes in S308), the fixed reception facility 140 outputs a warning regarding the absence of the slave unit 110 (S309). That is, in this case, the information processing unit 132 of the management device 130 outputs a warning regarding the absence of the slave device 110 being confirmed via the output unit 133 of the management device 130. Here, in the detection state (Yes in S303), when no confirmation information is received (No in S308), no warning is output.

Then, the fixed reception facility 140 repeats the above processing (S301 to S309). The fixed reception facility 140 may perform the above processing every time a signal is received from the slave unit 110, or may repeat the above processing at a time interval similar to the transmission interval, or a combination thereof. The above processing may be performed at different times.

For example, the fixed reception facility 140 may perform the reception process (S301) every time it is received, and repeat the other processes (S302 to S309) at a determination interval that is equal to or greater than the transmission interval. The determination interval may be, for example, 1 minute or another time interval.

Further, when a plurality of slave units 110 are used, the fixed reception facility 140 may perform the above processing (S301 to S309) for each of the plurality of slave units 110. In this case, in the detection state determination (S303), one or more child devices 110 in the detection state may be extracted together, or one or more child devices 110 in the non-detection state may be extracted together. Good.

When a plurality of slave units 110 and a plurality of mobile receivers 150 are used, detection information, confirmation information, and non-confirmation information regarding the slave units 110 associated with the mobile receiver 150 are received from each mobile receiver 150. May be.

In the above example, the fixed reception facility 140 outputs a warning (S309) when non-confirmation information is received from the mobile receiver 150 in the detection state (Yes in S303). The fixed reception facility 140 may output a warning when non-detection information indicating that the mobile device 150 is not detected by the mobile receiver 150 is received in the detection state (Yes in S303).

Thereby, for example, the fact that the slave unit 110 associated with the mobile receiver 150 is away from the mobile receiver 150 can be quickly transmitted to the other mobile receivers 150 and the like.

Further, the fixed reception facility 140 may continue to suppress the alarm output related to the detection of the slave unit 110 not being detected in a predetermined suppression period after the suppression of the alarm output related to the detection of the slave unit 110 being started. Good.

For example, in a state in which the slave unit 110 is not detected by the fixed reception facility 140, when confirmation information indicating that the slave unit 110 is confirmed is received, an alarm output regarding that the slave unit 110 is not detected is a predetermined output. It may continue to be suppressed during the suppression period. That is, in this case, the fixed reception facility 140 may not output an alarm during a predetermined suppression period. The predetermined deterrence period may be 10 minutes or another period.

Further, the fixed reception facility 140 may stop outputting the alarm when the alarm output is suppressed while the alarm is output. In addition, when receiving the confirmation information indicating that the presence of the child device 110 has been received, the fixed reception facility 140 may output a message indicating that the presence of the child device 110 has been confirmed.

Also, the processing order related to the detection information reception determination (S304) and the confirmation information reception determination (S305) may be reversed. Alternatively, these processes may be performed simultaneously.

Also, the processing regarding the detection information and the non-confirmation information may not be performed. For example, in the non-detection state (No in S303), the fixed reception facility 140 may perform the determination (S305) of reception of the confirmation information without performing the determination of reception of the detection information (S304). In addition, the fixed reception facility 140 does not perform the determination of reception of unconfirmed information (S308) and does not perform the warning output (S309) in the detection state (Yes in S303).

FIG. 19 is a flowchart showing the operation of the mobile receiver 150 shown in FIG. Specifically, the reception unit 151, the information processing unit 152, the transmission unit 153, and the input / output unit 154 included in the mobile receiver 150 illustrated in FIG. 11 may perform the operations illustrated in FIG.

For example, the mobile receiver 150 performs a reception process for receiving a signal transmitted from the slave unit 110 (S401). And the mobile receiver 150 performs the detection process for detecting the subunit | mobile_unit 110 according to the received signal (S402). Then, the mobile receiver 150 determines whether the slave unit 110 is in a detection state or a non-detection state (S403).

Specifically, in the mobile receiver 150, the reception unit 151 performs a reception process for receiving a signal transmitted from the slave unit 110. And the information processing part 152 performs a detection process by determining whether the received radio wave intensity | strength of a signal is larger than a threshold value.

Here, when the received radio wave intensity of the signal is larger than the threshold value, the information processing unit 152 detects the slave unit 110 that is the source of the signal. That is, the information processing unit 152 determines that the child device 110 is in a detection state. On the other hand, when the received radio wave intensity of the signal is not greater than the threshold value, the information processing unit 152 does not detect the slave unit 110 that is the signal source. The information processing unit 152 determines that the child device 110 is in a non-detected state.

As described above, when the received radio wave intensity of the signal is not larger than the threshold value, the case where the signal does not reach the mobile receiver 150 is included. That is, the information processing unit 152 determines that the slave unit 110 is in a non-detection state when the reception unit 151 does not receive a signal from the slave unit 110 at the transmission interval.

In the detection state (Yes in S403), the mobile receiver 150 transmits detection information indicating that the mobile device 110 is detected by the mobile receiver 150 to the fixed reception facility 140 (S404). Specifically, the information processing unit 152 of the mobile receiver 150 sends detection information indicating that the mobile device 110 is detected by the mobile receiver 150 to the fixed reception facility 140 via the transmission unit 153 of the mobile receiver 150. Send.

In the non-detection state (No in S403), the mobile receiver 150 notifies the holder of the mobile receiver 150 that the mobile device 150 is not detected by the mobile receiver 150 (S405). Specifically, the information processing unit 152 of the mobile receiver 150 notifies the holder of the mobile receiver 150 via the input / output unit 154 of the mobile receiver 150 that the mobile device 150 is not detected by the mobile receiver 150. To do.

Then, the mobile receiver 150 determines whether or not the mobile receiver 150 has been notified from the holder of the mobile receiver 150 that the presence of the slave unit 110 has been confirmed (S406). Specifically, the information processing unit 152 of the mobile receiver 150 determines whether a notification that the presence of the slave unit 110 has been confirmed is input to the input / output unit 154 of the mobile receiver 150. For example, when the presence of the slave unit 110 is confirmed by the holder of the mobile receiver 150, a notification that the presence of the slave unit 110 has been confirmed is input to the input / output unit 154 of the mobile receiver 150.

When the mobile receiver 150 is notified that the presence of the slave unit 110 has been confirmed to the mobile receiver 150 (Yes in S406), the mobile receiver 150 confirms the presence of the slave unit 110. Confirmation information indicating this is transmitted to the fixed reception facility 140 (S407). Specifically, in this case, the information processing unit 152 of the mobile receiver 150 sends confirmation information indicating that the presence of the slave unit 110 has been confirmed to the fixed reception facility 140 via the transmission unit 153 of the mobile receiver 150. Send.

Also, the mobile receiver 150 determines whether or not the mobile receiver 150 has been notified from the holder of the mobile receiver 150 that the presence of the slave unit 110 has not been confirmed (S408). Specifically, the information processing unit 152 of the mobile receiver 150 determines whether a notification that the presence of the slave unit 110 is not confirmed has been input to the input / output unit 154 of the mobile receiver 150. For example, if the presence of the slave unit 110 is not confirmed by the holder of the mobile receiver 150, a notification that the presence of the slave unit 110 is not confirmed is input to the input / output unit 154 of the mobile receiver 150.

If the mobile receiver 150 is notified that the presence of the slave unit 110 is not confirmed (Yes in S408), the mobile receiver 150 does not confirm the presence of the slave unit 110. Is transmitted to the fixed reception facility 140 (S409). Specifically, in this case, the information processing unit 152 of the mobile receiver 150 sends non-confirmation information indicating that the presence of the slave unit 110 is not confirmed to the fixed reception facility 140 via the transmission unit 153 of the mobile receiver 150. Send.

In the non-detection state (No in S403), when it is not notified that the presence of the child device 110 has been confirmed or not confirmed (No in S406 and No in S408), the mobile receiver 150 confirms the confirmation information and the non-confirmation information. May not be transmitted. Alternatively, if it is not notified that the presence of the handset 110 has been confirmed before the elapse of the predetermined waiting period from the notification that the handset 110 is not detected, the mobile receiver 150 transmits non-confirmation information. Also good. The predetermined waiting period may be one minute or another period.

The mobile receiver 150 repeats the above processing (S401 to S409). The mobile receiver 150 may perform the above processing every time a signal is received from the slave unit 110, or may repeat the above processing at a time interval similar to the transmission interval, or a combination thereof. The above processing may be performed at different times.

For example, the mobile receiver 150 may perform the reception process (S401) every time it is received, and repeat the other processes (S402 to S409) at a determination interval that is equal to or greater than the transmission interval. The determination interval may be, for example, 1 minute or another time interval.

When a plurality of slave units 110 are used, the mobile receiver 150 may perform the above processing (S401 to S409) for each of the plurality of slave units 110. In this case, in the detection state determination (S403), one or more child devices 110 in the detection state may be extracted together, or one or more child devices 110 in the non-detection state may be extracted together. Good.

When a plurality of slave units 110 and a plurality of mobile receivers 150 are used, each mobile receiver 150 performs the above processing (S401 to S409) for the slave unit 110 associated with the mobile receiver 150. May be. Further, each mobile receiver 150 performs any of the above processes (S401 to S409) on the slave unit 110 associated with the mobile receiver 150, and the slave unit 110 associated with the mobile receiver 150. Not only the machine 110 but other processes may be performed.

FIG. 24 is a conceptual diagram showing non-detection notification in the mobile receiver 150 shown in FIG. The non-detection notification shown in FIG. 24 is a notification that the slave unit 110 is not detected, and is displayed on the mobile receiver 150 in a state where the slave unit 110 is not detected by the mobile receiver 150.

Specifically, C0002 is displayed as the slave unit identification information of the slave unit 110 that is not detected. In other words, the mobile receiver 150 notifies the holder of the mobile receiver 150 that the slave unit 110 having the identifier C0002 is not detected. The holder of the mobile receiver 150 confirms the presence / absence of the child device 110 having the identifier C0002 by confirming the presence / absence of the child wearing the child device 110 having the identifier C0002.

When the presence of the child device 110 is confirmed, the holder of the mobile receiver 150 moves to confirm that the presence of the child device 110 is confirmed by selecting “with child device” in response to the non-detection notification. Notify receiver 150. For example, in this case, the mobile receiver 150 transmits confirmation information including child device identification information indicating C0002 as an identifier of the child device 110 whose existence has been confirmed to the fixed reception facility 140.

If the presence of the child device 110 is not confirmed, the holder of the mobile receiver 150 selects “no child device” in response to the non-detection notification to confirm that the presence of the child device 110 is not confirmed. 150 is notified. For example, in this case, the mobile receiver 150 transmits non-confirmation information including slave unit identification information indicating C0002 as an identifier of the slave unit 110 whose existence is not confirmed to the fixed reception facility 140.

FIG. 25 is an image diagram showing an alarm output from the fixed reception facility 140 shown in FIG. The alarm shown in FIG. 25 is an alarm related to the fact that the slave unit 110 is not detected. For example, in a state where the slave unit 110 is not detected by the fixed reception facility 140, the alarm reception is not suppressed and the fixed reception facility 140. Specifically, the information may be displayed on the management device 130 configuring the fixed reception facility 140.

Specifically, C0002 is displayed as the slave unit identification information of the slave unit 110 that is not detected. That is, it is displayed as an alarm that the handset 110 having the identifier C0002 is not detected.

The alarm control system 100 can appropriately prompt a larger search by outputting an alarm as shown in FIG. Although the fixed reception facility 140 displays an alarm in the example of FIG. 25, the alarm may be output by transmitting the alarm as data to an external search engine server.

FIG. 26 is an image diagram showing a warning output from the fixed reception facility 140 shown in FIG. The warning shown in FIG. 26 is a warning related to the fact that the presence of the child device 110 is not confirmed. For example, in a state where the child device 110 is detected by the fixed reception facility 140, the child of the mobile receiver 150 performs a child operation. When the presence of the device 110 is not confirmed, it is displayed on the fixed reception facility 140.

Specifically, C0003 is displayed as the slave unit identification information of the slave unit 110 whose existence is not confirmed. That is, it is displayed as a warning that the presence of the slave unit 110 having the identifier C0003 is not confirmed.

The alarm control system 100 can appropriately prompt a search in the area 200 by outputting a warning as shown in FIG.

In an environment where a plurality of mobile receivers 150 are used, the fixed reception facility 140 may output a warning by transmitting the warning as data to the plurality of mobile receivers 150. Then, in each mobile receiver 150, a warning as shown in FIG. 26 may be displayed. Thereby, for example, the alarm control system 100 can appropriately prompt a plurality of instructors respectively holding a plurality of mobile receivers 150 to search for a child equipped with the child device 110.

In addition, for example, as described above, among mobile receivers 150 in which the slave unit 110 is not detected among the plurality of mobile receivers 150, it is confirmed that the slave unit 110 is detected by another mobile receiver 150. The information shown may be transmitted and a warning may be notified to the holder. As a warning in this case, the fact that the slave unit 110 is detected by another mobile receiver 150 and the mobile receiver identification information of the other mobile receiver 150 may be displayed.

In the alarm output, the fixed reception facility 140 may transmit the alarm as data to each mobile receiver 150 and an external search engine server. Then, in each mobile receiver 150, an alarm as shown in FIG. 25 may be displayed. Thereby, the alarm control system 100 can prompt the search engine to search for the child, and can prompt each instructor to cooperate in searching for the child.

The alarm control system 100 in the present embodiment notifies the holder of the mobile receiver 150 that the mobile device 150 is not detected by the mobile receiver 150. When the alarm control system 100 is notified by the holder of the mobile receiver 150 that the presence of the slave unit 110 has been confirmed, the alarm control system 100 receives the confirmation information indicating that the presence of the slave unit 110 has been confirmed. Wirelessly transmitted from the machine 150 to the fixed reception facility 140. Then, when the confirmation information is received by the fixed reception facility 140, the alarm control system 100 suppresses the output of the alarm.

Thereby, the alarm control system 100 can appropriately control the output of an alarm related to the fact that the slave unit 110 is not detected.

As described above, the alarm control system 100 according to one aspect of the present invention has been described based on the embodiments and the like, but the present invention is not limited to the above-described embodiments and the like. The present invention also includes a form obtained by subjecting the above-described embodiment and the like to modifications conceived by those skilled in the art, and another form realized by arbitrarily combining a plurality of components in the above-described embodiment and the like. It is.

For example, another component may execute a process executed by a specific component. In addition, the order in which the processes are executed may be changed, or a plurality of processes may be executed in parallel.

The fixed receiver 120 does not transmit the received radio wave intensity to the management device 130 every time a signal is received, and the slave unit 110 changes from the detection state to the non-detection state or from the non-detection state to the detection state. Information indicating the change may be transmitted to the management apparatus 130. Alternatively, the fixed receiver 120 may transmit information indicating the change to the management device 130 when the reception level specified according to the received radio wave intensity changes from a plurality of predetermined reception levels of, for example, about five levels. Good. Thereby, the amount of transmission data is reduced and packet collision is suppressed.

Further, the fixed receiver 120 may transmit information to the management apparatus 130 via another fixed receiver 120 without directly transmitting information to the management apparatus 130. In this case, the other fixed receiver 120 operates as a relay device that relays communication between the fixed receiver 120 and the management device 130. That is, each fixed receiver 120 may operate as a relay device. Similarly, the mobile receiver 150 may transmit information to the management apparatus 130 via the fixed receiver 120 without transmitting information directly to the management apparatus 130.

In the above example, it is expected that the slave unit 110 exists in the area 200. However, the area 200 may include a no entry area where the child device 110 is expected not to exist.

In this case, for example, the management device 130 estimates whether or not the slave unit 110 exists in the restricted entry area according to the reception radio wave intensity of the signal received from the slave unit 110 by each of the plurality of fixed receivers 120. Also good. The management device 130 may output an alarm regarding that the child device 110 is estimated to be in the restricted entry area when the child device 110 is estimated to exist in the restricted entry region.

In the above description, the alarm output related to the estimated presence of the handset 110 in the restricted entry area may not be suppressed according to the confirmation information indicating that the handset 110 has been confirmed.

In addition, in a state where the slave unit 110 and the mobile receiver 150 are away from the area 200, confirmation information indicating that the presence of the slave unit 110 has been confirmed, detection information indicating that the slave unit 110 is detected, and the like May be transmitted from the mobile receiver 150 to the fixed reception facility 140. Thereby, for example, even if the child and the instructor are away from the area 200, the alarm output can be appropriately controlled.

In the above example, the handset 110 is attached to a child at a campsite or the like, but may be attached to equipment at a construction site or the like in order to prevent loss of equipment at the construction site or the like. Or in order to suppress loss of goods in a store or a warehouse, you may attach to goods in a store or a warehouse.

Also, in the above, an example is shown in which detection information indicating that the slave unit 110 is detected is transmitted. The mobile receiver 150 and the fixed receiver 120 may transmit detection information based on the same standard, or may transmit detection information based on different standards. For example, when the mobile receiver 150 and the fixed receiver 120 transmit detection information based on different standards, the mobile receiver 150 includes the slave unit 110 associated with the mobile receiver 150 among the plurality of slave units 110. The detection information may be transmitted only with respect to.

In relation to the above, the mobile receiver 150 detects the slave unit 110 that is not associated with the mobile receiver 150 at a position away from the area 200 and transmits detection information to suppress the output of the alarm. Is not necessarily appropriate. Therefore, as described above, the mobile receiver 150 may transmit the detection information only for the slave unit 110 associated with the mobile receiver 150 among the plurality of slave units 110.

On the other hand, in an environment where the mobile receiver 150 exists in the area 200, the mobile receiver 150 and the fixed receiver 120 may transmit detection information based on the same standard.

Further, the present invention can be realized not only as the alarm control system 100 but also as a method including steps (processes) performed by each component constituting the alarm control system 100.

For example, these steps may be executed by a computer system. This computer system may be a system corresponding to the alarm control system 100. The present invention can be realized as a program for causing a computer system to execute the steps included in these methods. Furthermore, the present invention can be realized as a non-transitory computer-readable recording medium such as a CD-ROM on which the program is recorded.

For example, when the present invention is realized by a program (software), each step is executed by executing the program using hardware resources such as a processor and a memory of a computer system. That is, each step is executed by the processor obtaining data from a memory or the like and performing an operation, or outputting the operation result to a memory or the like.

In addition, a plurality of components included in the alarm control system 100 or the like may be realized as dedicated or general-purpose circuits, respectively. Two or more of these components may be realized as one circuit, or may be realized as two or more circuits.

Further, a plurality of components included in the alarm control system 100 or the like may be realized as an LSI (Large Scale Integration) that is an integrated circuit (IC). Two or more of these components may be individually made into one chip, or may be made into one chip so as to include a part or all of them. An LSI may be called a system LSI, a super LSI, or an ultra LSI depending on the degree of integration.

Further, the integrated circuit is not limited to an LSI, and may be realized by a dedicated circuit or a general-purpose processor. A programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor in which connection and setting of circuit cells inside the LSI can be reconfigured may be used.

Furthermore, if integrated circuit technology that replaces LSI emerges as a result of advances in semiconductor technology or other technologies derived from it, naturally, using this technology, it is possible to integrate a plurality of components included in the alarm control system 100 and the like. It may be done.

Hereinafter, typical configurations, modifications, effects, and the like of the alarm control system 100 according to an aspect of the present invention will be described.

(1) The alarm control system 100 according to an aspect of the present invention includes a fixed reception facility 140 and a mobile receiver 150.

The fixed reception facility 140 performs a first reception process for receiving a signal periodically and wirelessly transmitted from the slave unit 110, and detects the slave unit 110 according to the signal received in the first reception process. A first detection process is performed. The position for the fixed reception facility 140 to receive a signal is fixed.

The mobile receiver 150 performs a second reception process for receiving a signal periodically and wirelessly transmitted from the slave unit 110, and detects the slave unit 110 according to the signal received in the second reception process. A second detection process is performed. The position for the mobile receiver 150 to receive the signal is not fixed.

The mobile receiver 150 notifies the holder of the mobile receiver 150 that the slave unit 110 is not detected when the slave unit 110 is not detected by the mobile receiver 150. Further, the mobile receiver 150 indicates that the presence of the slave unit 110 has been confirmed when the holder of the mobile receiver 150 is notified to the mobile receiver 150 that the presence of the slave unit 110 has been confirmed. The confirmation information is transmitted to the fixed reception facility 140 wirelessly.

The fixed reception facility 140 suppresses output of an alarm related to the fact that the slave unit 110 is not detected when confirmation information is received from the mobile receiver 150 in a state where the slave unit 110 is not detected by the fixed reception facility 140.

Thereby, the alarm control system 100 can notify the holder of the mobile receiver 150 that the slave unit 110 is not detected in a state where the slave unit 110 is not detected by the mobile receiver 150. The alarm control system 100 relates to the fact that the slave unit 110 is not detected when the presence of the slave unit 110 is confirmed by the holder of the mobile receiver 150 in a state where the slave unit 110 is not detected by the fixed reception facility 140. Alarm output can be suppressed.

Therefore, the alarm control system 100 can appropriately control an alarm output related to the fact that the slave unit 110 is not detected.

(2) For example, the mobile receiver 150 may wirelessly transmit detection information indicating that the slave unit 110 is detected to the fixed reception facility 140 in a state where the slave unit 110 is detected by the mobile receiver 150. Good. Then, the fixed reception facility 140 may suppress the output of an alarm when detection information is received from the mobile receiver 150 in a state where the slave device 110 is not detected by the fixed reception facility 140.

As a result, the alarm control system 100 outputs an alarm regarding that the child device 110 is not detected when the child device 110 is detected by the mobile receiver 150 in a state where the child device 110 is not detected by the fixed reception facility 140. Can be deterred. Therefore, the alarm control system 100 can appropriately control the output of an alarm regarding that the slave unit 110 is not detected.

(3) For example, the fixed reception facility 140 may output an alarm when the output of the alarm is not suppressed in a state where the slave device 110 is not detected by the fixed reception facility 140. Thereby, the alarm control system 100 can output an alarm when the output of the alarm is not suppressed. That is, the alarm control system 100 can appropriately output an alarm.

(4) For example, when the fixed reception facility 140 does not detect the child device 110 in the fixed reception facility 140 in the first predetermined number of repetitions of the first reception process and the first detection process, and the alarm output is not suppressed, An alarm may be output. Thus, the alarm control system 100 can output an alarm when the slave unit 110 is not detected even if the first reception process and the first detection process are repeated for the first predetermined number of times. Therefore, the alarm control system 100 can output an alarm at an appropriate timing.

(5) For example, when the mobile receiver 150 does not detect the slave unit 110 in the second predetermined number of repetitions of the second reception process and the second detection process, the mobile receiver 150 indicates that the slave unit 110 is not detected. The holder of the mobile receiver 150 may be notified. Here, the second predetermined number of times is less than the first predetermined number of times.

As a result, the alarm control system 100 allows the mobile receiver 150 to detect when the slave unit 110 is not detected even if the second reception process and the second detection process are repeated a second predetermined number of times less than the first predetermined number of times. The holder can be notified that the handset 110 is not detected. Therefore, the alarm control system 100 can notify at an early timing that the child device 110 is not detected. Therefore, the alarm control system 100 can suppress the alarm output at an early timing.

(6) For example, the fixed reception facility 140 may output an alarm when the slave device 110 is not detected in the first predetermined period by the fixed reception facility 140 and the alarm output is not suppressed. Thereby, the alarm control system 100 can output an alarm when the handset 110 is not detected in the first predetermined period. Therefore, the alarm control system 100 can output an alarm at an appropriate timing.

(7) For example, when the mobile receiver 150 does not detect the mobile unit 110 in the second predetermined period shorter than the first predetermined period, the mobile receiver 150 indicates that the mobile unit 110 is not detected. The holder may be notified.

Thereby, the alarm control system 100 may notify the holder of the mobile receiver 150 that the slave unit 110 is not detected when the slave unit 110 is not detected in the second predetermined period shorter than the first predetermined period. it can. Therefore, the alarm control system 100 can notify the holder of the mobile receiver 150 at an early timing that the slave unit 110 is not detected. Therefore, the alarm control system 100 can suppress the alarm output at an early timing.

(8) For example, the fixed reception facility 140 may detect the slave unit 110 when the received radio wave intensity of the signal received by the fixed reception facility 140 is larger than the first threshold value. And the mobile receiver 150 may detect the subunit | mobile_unit 110, when the received radio wave intensity | strength of the signal received with the mobile receiver 150 is larger than a 2nd threshold value. Thereby, the alarm control system 100 can detect the subunit | mobile_unit 110 appropriately by the comparison with a received radio wave intensity | strength and a threshold value.

(9) For example, the second threshold value may be the same as the first threshold value. Thereby, the alarm control system 100 can detect the subunit | mobile_unit 110 similarly with the fixed reception equipment 140 and the mobile receiver 150. FIG.

(10) For example, the second threshold value may be larger than the first threshold value. Thereby, the alarm control system 100 can narrow the area | region where the subunit | mobile_unit 110 is detected by the mobile receiver 150 rather than the fixed reception equipment 140. FIG. Therefore, the alarm control system 100 can notify the holder of the mobile receiver 150 that the child device 110 is not detected when it is not detected in a narrower area.

Therefore, the alarm control system 100 can notify the holder of the mobile receiver 150 at an early timing that the slave unit 110 is not detected. Further, the alarm control system 100 can prompt the holder of the mobile receiver 150 not to leave the holder of the slave unit 110 or the like.

(11) For example, the mobile receiver 150 has a second threshold value for the received radio wave intensity of the signal in a state where the mobile device 150 is detected by the mobile receiver 150 than in a state where the mobile device 110 is not detected by the mobile receiver 150. May be reduced. Thereby, the alarm control system 100 can suppress frequent notification to the holder of the mobile receiver 150 when the received radio wave intensity changes near the threshold.

(12) For example, when the mobile receiver 150 is notified from the holder of the mobile receiver 150 to the mobile receiver 150 that the presence of the slave unit 110 is not confirmed, the mobile receiver 150 confirms that the presence of the slave unit 110 is not confirmed. The unconfirmed information shown may be transmitted to the fixed reception facility 140 wirelessly. The fixed reception facility 140 warns that the presence of the slave unit 110 is not confirmed when non-confirmation information is received from the mobile receiver 150 in a state where the slave unit 110 is detected by the fixed reception facility 140. It may be output.

Thereby, the alarm control system 100 can output a warning when the holder of the mobile receiver 150 moves away from the holder of the slave unit 110. That is, the alarm control system 100 can notify that the holder of the mobile receiver 150 is away from the holder of the slave unit 110.

(13) For example, the alarm control system 100 may include each of the plurality of mobile receivers 150 including the first mobile receiver 150 and the second mobile receiver 150 as the mobile receiver 150. Thereby, the alarm control system 100 can control the output of the alarm using the plurality of mobile receivers 150.

(14) For example, the first mobile receiver 150 notifies the holder of the first mobile receiver 150 that the slave unit 110 is not detected when the slave unit 110 is not detected by the first mobile receiver 150. May be performed. Specifically, the first mobile receiver 150 may perform this process only for the first slave unit 110 out of the first and

second slave units

110 and 110.

Also, the second mobile receiver 150 performs a process of notifying the holder of the second mobile receiver 150 that the slave unit 110 is not detected in a state where the slave unit 110 is not detected by the second mobile receiver 150. Also good. Specifically, the second mobile receiver 150 may perform this process only for the second slave unit 110 out of the first and

second slave units
