Description

  The present invention relates to a housing monitoring system for reporting an abnormality in a living room such as an apartment house to a manager or the like.

  Conventionally, in a home monitoring system, a wireless slave device carried by a resident and a management room parent device installed in a manager room where a manager is present are connected wirelessly. Then, when the resident operates the call button of the wireless slave unit, the management room master unit outputs a ringing tone. The manager listens to the ringing sound produced by the management room base unit and grasps the call from the resident.

  By the way, when a wireless slave unit is used, in order to grasp the movement of the resident carrying the wireless slave unit, the signal level of the transmission signal from the wireless slave unit received by the receiver installed in the living room is detected. A technique for determining that there is an abnormality in a resident in a living room when the value of the reception level does not change is known (for example, Patent Document 1).

  In the conventional house monitoring system including this patent document 1, since it is assumed that the resident is carrying the wireless slave unit, if the resident has forgotten to carry the wireless slave unit, the receiver receives it. Since the value of the signal level of the transmission signal from the wireless slave that does not change does not change, there is a problem that it is erroneously determined that there is an abnormality in the resident in the room.

  Moreover, in the house monitoring system described in Patent Document 1, it is determined that the resident is out when the signal level of the transmission signal from the wireless slave unit received by the receiver decreases. Therefore, if the resident forgets to carry the wireless slave unit, the signal level value of the outgoing signal from the wireless slave unit received by the receiver does not change, so it is determined whether the resident is out. There was a problem that it was impossible to do.

JP 2005-11220 A

  The present invention has been made to solve such a problem, and it is determined whether or not a resident is going out after determining whether or not the resident is carrying a wireless handset. However, when an abnormality occurs in the resident, it is intended to be able to report it to a manager.

  In order to solve the above-described problems, in the present invention, outing information indicating that the resident is out is input, and the value of the reception level of the transmission signal transmitted from the wireless slave device carried by the resident is predetermined. When it is determined that the value is equal to or less than the value, and when it is determined that the value of the reception level is larger than the predetermined value and the value is not changed, the resident is set to be absent. On the other hand, when the outing information is input and the value of the reception level is larger than the predetermined value and it is determined that there is a change in the value, and when the outing information is not input, the resident is present in the room. And set. When the presence level is set and the reception level value does not change for a predetermined time, the resident is notified that an abnormality has occurred.

  According to the present invention configured as described above, when the outing information is input and the value of the reception level from the wireless slave unit becomes a predetermined value or less, the resident carries the wireless slave unit and goes out. Judging. Also, if the outing information is input and the value of the reception level from the wireless slave is greater than the predetermined value and there is no change in the value, it is determined that the resident has forgotten to carry the wireless slave and went out. doing. Therefore, it can be determined whether the resident is going out after determining whether the resident is carrying the wireless handset. On the other hand, when the outing information is input and the value of the reception level from the wireless slave unit is larger than the predetermined value and there is a change in the value, there is a resident other than the outing resident. Judging. If the outing information is not input, it is determined that the resident is in the room. If it is determined that the resident is in the room and there is no change in the reception level from the wireless slave unit for a predetermined time, the resident is informed that an abnormality has occurred and may notify the manager. it can.

It is a block diagram which shows the structural example of the dwelling unit monitoring system by this embodiment. It is a figure which shows the example at the time of the resident carrying a wireless subunit | mobile_unit with the dwelling unit monitoring system of this embodiment, and going out. It is a figure which shows the example when a resident goes out without carrying a wireless cordless handset in the dwelling unit monitoring system of this embodiment. It is a figure which shows the example in case a resident carries out a wireless cordless handset in the dwelling unit monitoring system of this embodiment, and another resident is left.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an arrangement example of the dwelling unit monitoring system according to the present embodiment. FIG. 2 is a block diagram illustrating a configuration example of the dwelling unit monitoring system according to the present embodiment. As shown in FIGS. 1 and 2, the dwelling unit monitoring system according to the present embodiment includes a wireless slave device 1, a receiver 10, a reception level detection device 20, an outing detection device 30, an analysis device 40, and a management room parent device 50. Configured. Here, the wireless slave device 1 is carried by a resident and is hung on the resident's neck or the like by a string attached to the housing of the wireless slave device 1. Further, when there are a plurality of residents in the living room, the wireless slave device 1 is carried by each of the residents. Note that an operation button that is operated when the resident calls an administrator or the like may be provided on the wireless slave device 1. Of course, a plurality of rooms may exist.

  The wireless slave unit 1 includes a slave unit control unit 2, a slave unit storage unit 3, and an operation unit 4. The slave unit control unit 2 controls each component of the wireless slave unit 1. The handset storage unit 3 stores handset identification information uniquely assigned to the wireless handset 1. The subunit | mobile_unit control part 2 acquires subunit | mobile_unit identification information from the subunit | mobile_unit control part 3, and produces | generates the transmission signal containing this subunit | mobile_unit identification information. Here, the transmission signal is for confirming the location of the wireless slave unit 1. The subunit | mobile_unit transmission part 4 transmits the transmission signal produced | generated in the subunit | mobile_unit control part 2 for every fixed period (for example, 1 second etc.).

  The receiver 10 receives a transmission signal from the wireless slave unit 1 and outputs the received transmission signal to the reception level detection device 20. Here, the receiver 10 is installed in a living room, and is arranged so that a resident can receive a transmission signal from the wireless slave unit 1 wherever the resident is. Further, the receiver 10 receives a transmission signal transmitted from the wireless slave device 1 via an antenna (not shown). If one receiver 10 cannot cover the entire area of the room, two or more receivers 10 may be used.

  The reception level detection apparatus 20 receives the transmission signal output from the receiver 10 and detects the value of the reception level of the transmission signal. Here, the reception level detection device 20 detects the value of the reception level of the transmission signal every certain period (for example, 1 second), and the receiver 10 cannot receive the transmission signal from the wireless slave unit 1. In this case, the reception level is detected as 0. Usually, the closer the radio handset 1 is to the antenna, the larger the reception level value of the transmission signal detected by the reception level detection device 20.

  The outing detection device 30 is operated by a resident when going out, and outputs outing information when operated. Here, the outing detection device 30 may be operated by a lock performed by the resident from outside the living room, or operated by taking out the key from a key holder that holds the key when the resident goes out. You may do it. Here, when there are a plurality of residents in the room, a key used for locking and a key held in the key holder are prepared for each of the residents. Therefore, when one of the two residents goes out, even if the resident who goes out locks from outside, the remaining resident can lock out the room and go out. Further, when one of the two residents goes out, even if the outing resident takes out the key from the key holder, the remaining resident's key is held in the key holder.

  The analysis device 40 is installed in a living room or outside a living room. The analysis device 40 includes a control unit 41, an interface 42, a reception level storage unit 43, an absence determination unit 44, and a timer unit 45. The control unit 41 controls each component of the analysis device 40. The interface 42 is for connecting the analysis device 40 to the reception level detection device 20 and the outing detection device 30. The interface 42 receives the reception level value from the reception level detection device 20. Further, the outing information is input from the interface 42 and the outing detecting device 30. The interface 42 is used to connect the analysis device 40 and the management room parent device 50, and is connected to the parent device interface 52 by wire. Here, an abnormality notification signal described later is output from the interface 42 to the management room master unit 50.

  The reception level storage unit 43 stores the value of the reception level input by the interface 42 in time series. Here, the reception level storage unit 43 only needs to store the reception level value for a certain period. For example, if the reception level value for 24 hours can be stored, the previous reception level value can be stored. May be automatically deleted.

  The presence / absence determination unit 44 determines whether or not the value of the reception level input by the interface 42 is equal to or less than a predetermined value when the interface 42 inputs the outing information. When it is determined that the input reception level value is equal to or less than the predetermined value, the absence determination unit 44 determines that the resident is absent. As described above, when the resident goes out and the value of the reception level from the wireless slave unit 1 is equal to or less than the predetermined value, the resident goes out with the wireless slave unit 1 as shown in FIG. Shows the case. That is, before the resident goes out, the wireless handset 1 is present together with the resident in the room, so the value of the reception level from the wireless handset 1 is larger than a predetermined value, and the resident Since the wireless handset 1 is not present in the room after going out, the value of the reception level from the wireless handset 1 is considered to be in a state of a predetermined value or less.

  Further, when the interface 42 inputs the outing information, when the presence / absence determination unit 44 determines that the value of the reception level input by the interface 42 is larger than a predetermined value, the presence / absence determination unit 44 Is compared with the reception level value stored in the reception level storage unit 43 in time series. That is, the presence / absence determination unit 44 determines whether or not the reception level of the transmission signal from the wireless slave device 1 is changed before and after the resident goes out. When it is determined that there is no change by comparing the input reception level value with the stored reception level value, the presence / absence determination unit 44 determines that the resident is absent. Here, the state in which the input reception level value and the stored reception level value are not changed is not only the case where the both reception level values are exactly the same, but also a certain range of difference. A case is included. That is, if it is within this range, it is determined that there is no change in both.

  As described above, when the resident has gone out, there is no change in the value of the reception level from the wireless slave unit 1. As shown in FIG. 4, the resident does not carry the wireless slave unit 1. Shows the case of going out. That is, before the resident goes out, the wireless handset 1 is placed in a certain place in the living room, and after the resident goes out, the wireless handset 1 remains in the place. it is conceivable that.

  Further, when the interface 42 inputs the outing information, when the presence / absence determination unit 44 determines that the value of the reception level input by the interface 42 is larger than a predetermined value, the presence / absence determination unit 44 Is compared with the reception level value stored in the reception level storage unit 43 in time series. When the input reception level value is compared with the stored reception level value and it is determined that there is a change, the presence / absence determination unit 44 determines that the resident is present. In this way, when the resident has gone out, there is a change in the value of the reception level from the wireless slave unit 1 as shown in FIG. In this example, two people), one resident carries the wireless handset 1 and goes out, and another resident is shown in the room. In addition, since the transmission signal transmitted from the wireless slave unit 1 includes the slave unit identification information, the resident can be identified. The presence / absence determination unit 44 determines that the resident is present even when the interface 42 does not input the outing information. This has shown the state where the resident in a living room has not gone out.

  Here, the predetermined value used as the value of the reception level is a value at which the receiver 10 receives a transmission signal when the resident goes out of the room. Therefore, when the interior of the dwelling unit is shielded so that the receiver 10 cannot receive any transmission signal from the wireless slave unit 1 outside the room, the predetermined value is close to zero. Note that, in the present embodiment, the case where the value is equal to or less than the predetermined value and the case where the value is larger than the predetermined value are separated from each other. For example, the two may be separated depending on whether it is less than a predetermined value or greater than a predetermined value.

  The time measuring unit 45 is for measuring time, starts measurement in response to an instruction from the control unit 41, ends measurement in response to an instruction from the control unit 41, and starts (resets) measurement again. Here, when the presence / absence determination unit 44 determines that the user is in the room, the analysis device 40 performs the following operation. The control unit 41 operates the time measuring unit 45. When the time measuring unit 45 measures time, the reception level value input by the interface 42 is compared with the reception level value stored in the reception level storage unit 43. When the absence determination unit 44 determines, the control unit 41 resets the time measuring unit 45.

  On the other hand, the control unit 41 determines whether or not the time measured by the time measuring unit 45 is equal to or longer than a predetermined time. If the time is equal to or longer than the predetermined time, an abnormality notification signal indicating that an abnormality has occurred in the resident. Is generated. The generated abnormality notification signal is output to the management room base unit 50 through the interface 42. Here, information for identifying a room or a resident is added to the abnormality notification signal. In addition, when the absence determination unit 44 determines that the absence is present, the timer unit 45 does not start measurement. Therefore, the control unit 41 does not generate an abnormality notification signal.

  The management room base unit 50 is installed in a management room or the like, and is used by a manager to monitor the status of each room in the management room. The management room base unit 50 includes a base unit control unit 51, a base unit interface 52, and a notification unit 53. The base unit control unit 51 controls each component of the management room base unit 50. The base unit interface 52 is used to connect the management room base unit 50 and the analysis device 40, and is connected to the interface 42 by wire. The base unit interface 52 inputs an abnormality report signal from the analysis device 40.

  The notification unit 53 notifies the resident (or the room) that an abnormality has occurred. Here, the notification unit 53 includes a sound emitting device such as a speaker and a display device such as a liquid crystal display. In addition, when notifying that the abnormality has occurred in the notification unit 53, the information on the target resident (or room) may be displayed on the display device by the identification information included in the abnormality notification signal. good. The base unit control unit 51 operates the notification unit 53 when the base unit interface 52 inputs an abnormality notification signal. Upon receiving this notification, the manager confirms the status of the room.

  As described above in detail, according to the present embodiment, the receiver 10 that receives the transmission signal from the wireless slave device 1 carried by the resident is installed in the living room, and the transmission signal received by the receiver 10 is received. A reception level detection device 20 that detects a value of the reception level, an outing detection device 30 that outputs outing information indicating that a resident is out by a predetermined operation, and an analysis device 40 that analyzes the detection results Is provided. When the analysis device 40 inputs the outing information output from the outing detection device 30 and the presence / absence determination unit 44 determines that the value of the reception level detected by the reception level detection device 20 is equal to or less than a predetermined value, When the presence / absence determination unit 44 determines that the value of the reception level detected by the reception level detection device 20 is greater than a predetermined value, and the presence / absence determination unit 44 determines that there is no change in the value. Sets that the resident is absent. On the other hand, when the analysis device 40 inputs the outing information output from the outing detection device 30, the presence / absence determination unit 44 determines that the value of the reception level detected by the reception level detection device 20 is greater than a predetermined value, When the presence / absence determination unit 44 determines that there is a change in the value, and when the outing information is not input from the outing detection device 30, it is set that the resident is in the room. When the control unit 41 of the analysis device 40 determines that the reception level value detected by the reception level detection device 20 has not changed for a predetermined time when it is set in the room, the control unit 41 is resident. An abnormality notification signal indicating that an abnormality has occurred is generated and output to the management room master unit 50. The base unit control unit 51 of the management room base unit 50 that has input the abnormality report signal causes the notification unit 43 to operate.

  As a result, when the outing information is input and the value of the reception level from the wireless slave unit 1 becomes a predetermined value or less, it is determined that the resident has gone out with the wireless slave unit 1. In addition, when the outing information is input and the value of the reception level from the wireless slave unit 1 is larger than the predetermined value and there is no change in the value, the resident forgets to carry the wireless slave unit 1 and goes out. Judging. Therefore, it can be determined whether the resident is going out after determining whether the resident is carrying the wireless handset 1 or not. On the other hand, when the outing information is input and the value of the reception level from the wireless slave unit 1 is larger than the predetermined value and the value is changed, a resident other than the outing resident is present in the room. Judging. If the outing information is not input, it is determined that the resident is in the room. When it is determined that the resident is in the room and there is no change in the reception level from the wireless slave unit 1 for a predetermined time, the resident is informed that an abnormality has occurred, and the manager is notified. Can do.

  In addition, in embodiment mentioned above, although the reception level detection apparatus 20 and the going-out detection apparatus 30 are installed in the living room, it is not limited to this. For example, the reception level detection device 20 or the outing detection device 30 may be provided outside the room.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly.
