Abstract

<P>PROBLEM TO BE SOLVED: To reduce a superintendent's load of safety confirmation. <P>SOLUTION: A dwelling unit control device 200 in each dwelling unit sequentially stores in a detection information storage part 320 detection information indicating the presence of an occupant's behavior in the dwelling unit and the time of detection of the occupant's behavior. If detection information indicating the presence of the occupant's behavior within a predetermined time before the reception of an advance safety confirmation signal sent from a master unit 220 is stored in the detection information storage part 320, each dwelling unit control device 200 sends relevant determination result information to the master unit 220. On receiving the determination result information, the master unit 220 excludes the dwelling unit control device 200 that has sent the determination result information from safety confirmation subjects to presume that the occupant is safe in the dwelling unit where the occupant's behavior was detected within the predetermined time just before safety confirmation, which saves the trouble of sending a safety confirmation signal for safety confirmation. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a safety confirmation system for confirming the safety of a resident in a dwelling unit.

  In recent years, in a housing complex for elderly people consisting of multiple dwelling units, the manager of the management room regularly checks the safety of residents in the dwelling units once a day. It is desirable to respond appropriately. Therefore, a safety confirmation system that can periodically confirm the safety of residents in the dwelling unit has been proposed.

  FIG. 5 is a block diagram showing an example of the overall configuration of a conventional safety confirmation system 1. In the conventional safety confirmation system 1, each dwelling unit 2 is provided with a response button 3, a dwelling unit control device 4, and a timer counter 5. In the management room 6, a master unit 7, a display 8, and a safety confirmation button 10 are installed. As shown in FIG. 6, the display 8 displays a safety status information display screen including safety status information 9 a to 9 o indicating the safety status of residents in each dwelling unit 2. Here, the safety status information includes room number information indicating the room number of each dwelling unit 2 and safety information indicating the safety status of each dwelling unit 2. The safety information is, for example, information indicating either a normal state (safe) or an abnormal state.

  The safety confirmation button 10 is pressed by the administrator when confirming the safety of a resident in each dwelling unit 2. When the administrator presses the safety confirmation button 10, a safety confirmation signal is transmitted from the master unit 7 to the dwelling unit control device 4 installed in each dwelling unit 2. When the dwelling unit control device 4 receives the safety confirmation signal, the timer function of the timer counter 5 starts its operation, and the dwelling unit control device 4 notifies the resident that the safety confirmation is being performed. Here, the timer counter 5 calculates the elapsed time from the time when the dwelling unit control device 4 receives the safety confirmation signal to the current time.

  On the other hand, in each dwelling unit 2 in which the dwelling unit control device 4 is informed that the safety is being confirmed, the response button 3 is displayed before the elapsed time calculated by the timer counter 5 exceeds a predetermined time (for example, 5 minutes). When the operation is performed, a response signal is transmitted from the dwelling unit control device 4 to the base unit 7. When the base unit 7 receives the response signal from the dwelling unit control device 4, the display screen of the display 8 indicates that the resident in the dwelling unit where the dwelling unit control device 4 that has transmitted the response signal is installed is safe. Safety status information is displayed. On the other hand, when the base unit 7 does not receive the response signal from the dwelling unit control device 4, the display screen of the display 8 shows a resident in the dwelling unit where the dwelling unit control device 4 that has not transmitted the response signal is installed. Safety status information indicating that there is an abnormality is displayed.

  However, in this conventional safety confirmation system 1, the resident must operate the response button 3 before the elapsed time calculated by the timer counter 5 exceeds a predetermined time. There was a problem that behavior was restricted.

In response to this problem, a technology has been proposed that can accurately confirm the safety of a resident regardless of whether or not the resident has responded to the safety confirmation from the manager of the control room. (For example, refer to Patent Document 1). The technique described in Patent Document 1 is characterized in that emergency call detection from a resident to an administrator, detection of a resident's body, detection of use of water, detection of use of an intercom, and the like are used for confirmation of the resident's safety. . According to the technique described in Patent Document 1, the administrator can accurately check the resident's safety, not only when the resident responds by operating the response button, and the resident at the time of the safety confirmation response The restrictions on the person's behavior can also be eliminated.
JP 2001-309062 A

  However, in the technique described in Patent Document 1, the burden on the resident is reduced at the time of safety confirmation by using the emergency call detection from the resident to the manager, the human body detection of the resident, etc. for the safety confirmation of the resident. However, in order to confirm the safety of residents in each residence, the number of safety status information that the administrator of the management room must check on the display remains the same, so there are many housing units with a particularly large number of units. However, there is a problem that the work of confirming the safety of residents in each dwelling unit by the administrator is complicated.

  The present invention has been made to solve such problems, and it is an object of the present invention to reduce the burden of safety confirmation work by an administrator.

  In order to solve the above-described problem, in the present invention, the dwelling unit control device of each dwelling unit detects the presence / absence of the resident's behavior in each dwelling unit and the detection information indicating the date and time when the presence / absence of the resident's behavior is detected. Are sequentially stored in the detection information storage unit. And at the time of execution of safety confirmation, first, a safety advance confirmation signal is transmitted from the master unit to the dwelling unit control device of each dwelling unit. In each dwelling unit control device, it is determined whether or not detection information indicating that the resident's action has been performed within a predetermined time before receiving the safety prior confirmation signal is stored in the detection information storage unit, and stored. If so, determination result information indicating that is transmitted to the parent device. The master unit that has received the determination result information sets the resident of the dwelling unit in which the dwelling unit control apparatus that has transmitted the determination result information is not subject to safety confirmation.

  According to the present invention configured as described above, with respect to a dwelling unit in which the resident's behavior is detected within the latest predetermined time for confirming the safety, the resident's safety is safe by the determination process based on the safety prior confirmation signal. (Normal state), and it is not necessary to send a safety confirmation signal to confirm safety. For this reason, for example, if the safety status information of a resident who is estimated to be safe (normal state) is excluded from the display target (or made inconspicuous), the administrator will be a resident in all dwellings. Compared with the prior art in which the safety status information must be confirmed, the number of residents who must actually confirm the safety status information displayed on the display as a result of the safety confirmation is reduced. Therefore, the load of the safety confirmation work by the administrator can be reduced.

The safety normality information shown is output to the safety status information transmission unit 480 (step S360). Next, safety status information transmission section 480 receives the safety normal information output from safety determination section 460, and transmits safety status information including the safety normal information to base unit 220 (step S380).

  On the other hand, when safety determination unit 460 determines that the response operation detection signal is not input even if the elapsed time exceeds the predetermined time (NO in step S340), safety determination unit 460 indicates that the resident has an abnormality. The safety abnormality information indicating this is output to the safety status information transmission unit 480 (step S400). Next, safety status information transmission section 480 receives the safety abnormality information output from safety determination section 460, and transmits safety status information including the safety abnormality information to base unit 220 (step S420).

  The safety status information receiving unit 580 of the parent device 220 determines whether the safety status information is received from the safety status information transmitting unit 480 (step S440). If safety status information reception unit 580 determines that safety status information is not received from safety status information transmission unit 480 (NO in step S440), the process transitions to step S440, and safety status information is received. The determination process is repeated until On the other hand, when safety status information reception unit 580 determines that safety status information has been received from safety status information transmission unit 480 (YES in step S440), safety status information reception unit 580 sets the received safety status information. To the unit 600.

  Next, the setting unit 600 inputs the safety status information output from the safety status information receiving unit 580, and determines whether the safety status information includes safety normal information (step S460). The setting unit 600 actually receives this determination by the safety status information receiving unit 580 from the safety status information transmitting unit 480 included in the dwelling unit control device 200 of each dwelling unit to which the safety confirmation signal transmitting unit 640 has transmitted the safety confirmation signal. This is done for each safety status information. If the setting unit 600 determines that safety normality information is included in the safety status information (YES in step S460), the setting unit 600 includes the dwelling unit information stored in the dwelling unit information storage unit 500. The value of the safety status information included in the dwelling unit information corresponding to the dwelling unit ID of the dwelling unit control apparatus 200 that has transmitted the safety status information is changed from “Checking safety” to “Normal state”. The safety status information display unit 620 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and is included in the dwelling unit information in which the value of the safety status information is changed from “being confirmed safety” to “normal state”. For the dwelling unit corresponding to the dwelling unit ID, the safety status information indicating the safety status of the resident is changed from “under safety confirmation” to “normal state” and displayed on the display 240 (step S480).

  On the other hand, when the setting unit 600 determines that safety normal information is not included in the safety status information (that is, safety abnormality information is included in the safety status information) (NO in step S460), the setting unit 600 Shows the value of the safety status information included in the dwelling unit information corresponding to the dwelling unit that has transmitted the safety status information to the safety status information receiving unit 580 among the dwelling unit information stored in the dwelling unit information storage unit 500. Change the setting from “Medium” to “Error”. The safety status information display unit 620 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and is included in the dwelling unit information in which the value of the safety status information is changed from “being confirmed safety” to “abnormal state”. For the dwelling unit corresponding to the dwelling unit ID, the safety status information indicating the safety status of the resident is changed from “under safety confirmation” to “abnormal state” and displayed on the display 240 (step S500). At the same time, the warning unit 660 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and is included in the dwelling unit information in which the value of the safety status information is changed from “being confirmed safety” to “abnormal state”. A warning sound for warning that there was an abnormality in the resident in the dwelling unit corresponding to the dwelling unit ID is output from the speaker 260 (step S520). After the process of step S480 or S520 is completed, the safety confirmation system 100 ends the process in FIG.

  As explained in detail above, in the first embodiment, the dwelling unit control device 200 of each dwelling unit indicates the presence or absence of the resident's action in each dwelling unit and the date and time when the presence or absence of the resident's action is detected. The detection information is sequentially stored in the detection information storage unit 320. When executing the safety confirmation, first, a safety advance confirmation signal is transmitted from the parent device 220 to the dwelling unit control device 200 of each dwelling unit. Each dwelling unit control device 200 determines whether or not detection information indicating that the resident's action has occurred within a predetermined time before receiving the safety prior confirmation signal is stored in the detection information storage unit 320. If it is stored, determination result information indicating that is transmitted to the base unit 220. The base unit 220 that has received the determination result information sets the resident of the dwelling unit in which the dwelling unit control apparatus 200 that has transmitted the determination result information is excluded from the safety confirmation target, and the safety status of the resident The information (normal state) is removed from the display target of the safety status information display screen displayed on the display 240.

  As described above, for the dwelling unit in which the resident's behavior is detected within the latest predetermined time for confirming the safety, the safety of the resident is determined by the determination process for confirming the detection information in the detection information storage unit 320 based on the safety prior confirmation signal. Is safe (normal state), and it is not necessary to send a safety confirmation signal to confirm the safety. Furthermore, the administrator only needs to confirm the safety status information corresponding to the safety confirmation target dwelling displayed on the display 240 as a result of the safety confirmation. For this reason, it is necessary to confirm the safety status information actually displayed on the display 240 as a result of the safety confirmation, as compared with the conventional technology in which the administrator has to confirm the safety status information of the resident in all the dwelling units. The number of residents will be reduced. Therefore, the load of the safety confirmation work by the administrator can be reduced.

  Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a block diagram showing an example of the overall configuration of a safety confirmation system 100 ′ according to the second embodiment. In FIG. 4, those given the same reference numerals as those shown in FIG. 1 have the same functions, and therefore redundant description is omitted here.

  In the second embodiment, the safety confirmation system 100 ′ further includes an electric lock 700, an in-room setting button 720, and a key holder switch 740. The electric lock 700, the occupancy setting button 720, and the key chain switch 740 are installed in each dwelling unit of the apartment house. The dwelling unit control apparatus 200 ′ further includes an absence detection unit 760 and an absence detection signal transmission unit 780. Master unit 220 ′ includes safety prior confirmation signal transmission unit 540 ′ and setting unit 600 ′ instead of safety prior confirmation signal transmission unit 540 and setting unit 600 of FIG. Base unit 220 'further includes an absence detection signal receiving unit 800 and a non-occupancy setting unit 820.

  The electric lock 700 is installed at the entrance door of each dwelling unit, and is electrically connected to the dwelling unit control device 200 ′ so as to be communicable. When the electric lock 700 detects the locking of the entrance door from the outside of the room, the electric lock 700 estimates that the resident has gone out and outputs a resident absence detection signal indicating the absence of the resident to the dwelling unit control device 200 ′. To do. However, when the electric lock 700 receives a control signal to be described later from the occupancy setting button 720, even if the entrance door is locked from the outside of the room, it is not estimated that the occupant has gone out, and no resident is present. The detection signal is not output to the dwelling unit control apparatus 200 ′.

  The occupancy setting button 720 is installed at a predetermined location of each dwelling unit and is electrically connected to the electric lock 700 so as to be communicable. The occupancy setting button 720 is used when any resident presses when another resident is present in the dwelling unit when the resident goes out. When it is detected that the occupant setting button 720 is pressed by the resident, the electric lock 700 that detects the lock of the entrance door from the outside by the resident who has gone out sends the occupant absence detection signal to the dwelling unit control device 200 ′. A control signal for invalidating the function to be output is output to the electric lock 700.

  The key ring switch 740 is installed at a predetermined location of each dwelling unit, and is electrically connected to the dwelling unit control device 200 ′ so as to be communicable. This key holder switch 740 detects that there is no card key in the key holder for inserting the card key when the resident is in the room (that is, the resident is out), and A resident absence detection signal indicating the absence of the resident is output to the dwelling unit control apparatus 200 '. There may be two or more key holders for inserting card keys. In this case, the key holder switch 740 outputs a resident absence detection signal to the dwelling unit control device 200 ′ when the card key is not inserted into all the key holders.

  In each dwelling unit, all of the electric lock 700, the occupancy setting button 720, and the key holder switch 740 are not necessarily provided. For example, only the electric lock 700 and the occupancy setting button 720 may be provided. Alternatively, only the key holder switch 740 may be provided. In particular, when there is one resident in one dwelling unit, the dwelling unit may include only the electric lock 700. Alternatively, only the key holder switch 740 may be provided and only one key holder may be provided.

  When the absence detection unit 760 receives the resident absence detection signal output from the electric lock 700 or the key holder switch 740, the absence detection unit 760 detects the absence of the resident in the dwelling unit. Moreover, when the absence detector 760 detects the absence of a resident in the dwelling unit, the absence detector 760 outputs an absence detection signal indicating that fact to the absence detection signal transmitter 780. Absence detection signal transmission section 780 receives the absence detection signal output from absence detection section 760 and transmits the absence detection signal to base unit 220 '. Here, the absence detection signal includes a dwelling unit ID for identifying the dwelling unit in which the absence of the resident is detected.

  The absence detection signal receiving unit 800 of the parent device 220 ′ receives the absence detection signal transmitted from the absence detection signal transmitting unit 780. Then, the absence detection signal receiving unit 800 outputs the received absence detection signal to the setting unit 600 ′. The non-occupancy setting unit 820 is input through the user operation among the dwelling unit information stored in the dwelling unit information storage unit 500 in response to a user operation on the operation unit (not shown). The dwell unit information including the dwell unit ID (corresponding to) is searched. Then, the non-occupancy setting unit 820 sets “normal state (non-occupancy)” to the value of the safety status information included in the searched dwelling unit information.

  The setting unit 600 ′ has the following functions in addition to the functions of the setting unit 600 of FIG. That is, when the absence detection signal output from the absence detection signal receiving unit 800 is input, the setting unit 600 ′ sets a resident in the dwelling unit corresponding to the dwelling unit ID included in the absence detection signal as a safety confirmation target. To do. Specifically, the setting unit 600 ′ uses the value of the safety status information included in the dwelling unit information corresponding to the dwelling unit with the dwelling unit ID included in the absence detection signal among the dwelling unit information stored in the dwelling unit information storage unit 500. Set to "Normal status (absent)".

  The safety status information display unit 620 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and displays the dwelling unit ID included in the dwelling unit information in which the value of the safety status information is set to “normal state (absent)”. The safety status information indicating the safety status of the resident in the corresponding dwelling unit is excluded from the display target of the safety status information display screen displayed on the display 240. The safety status information display unit 620 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and is included in the dwelling unit information in which the value of the safety status information is set to “normal state (non-occupied)”. The safety status information indicating the safety status of the resident in the dwelling unit corresponding to the dwelling unit ID is excluded from the display target of the safety status information display screen displayed on the display 240.

  The safety prior confirmation signal transmission unit 540 ′ refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and the value of the safety status information is “normal state (absent)” or “normal state (not occupancy)”. A safety advance confirmation signal is transmitted to the dwelling unit control device 200 ′ installed in the dwelling unit corresponding to the dwelling unit ID other than the dwelling unit ID included in the dwelling unit information set in the crab (that is, the dwelling unit subject to prior confirmation of safety).

  As described in detail above, in the second embodiment, the master unit 220 ′ determines whether the resident of the dwelling unit in which the dwelling unit control device 200 ′ that has detected the absence of the resident is detected by the absence detecting unit 760 is safe. In addition to being set as a confirmation target, the safety status information of the resident is excluded from the display target of the safety status information display screen displayed on the display 240. Furthermore, the base unit 220 ′ sets the resident of the dwelling unit in which the dwelling unit control device 200 ′ corresponding to the dwelling unit set as non-occupied in the non-occupancy setting unit 820 is set as a safety confirmation target, The safety status information of the resident is removed from the display target of the safety status information display screen displayed on the display 240. As described above, since it is not necessary to send a safety confirmation signal to the dwelling unit in which the absence of the resident is detected and the dwelling unit in which no occupant is set, it is not necessary to confirm the safety, compared with the first embodiment. Actually, the number of residents who have to confirm the safety status information displayed on the display 240 as a result of the safety confirmation is further reduced. Therefore, the load of the safety confirmation work by the manager can be further reduced.

  In the second embodiment, the occupants whose occupancy is detected by the occupancy detection unit 760 are set out of the safety confirmation target, and the occupants in the dwelling unit where the occupancy is set by the non-occupancy setting unit 820 are set. Although an example of setting out of the safety confirmation target has been described, the present invention is not limited to this. For example, only a resident who has been absent by the absence detection unit 760 or a resident in a dwelling unit in which no occupancy has been set by the non-occupancy setting unit 820 is set as a safety confirmation target. Anyway.

  In the first and second embodiments, the response operation detection signal is output from the response operation detection unit 440 before the elapsed time indicated by the elapsed time information output from the timer counter 420 exceeds a predetermined time. In this case, an example in which the safety determination unit 460 outputs the safety normal information indicating that the resident is safe to the safety status information transmission unit 480 has been described, but the present invention is not limited to this. For example, when the presence / absence detection unit 300 determines that the resident's action has occurred before the elapsed time indicated by the elapsed time information output from the timer counter 420 exceeds a predetermined time, the safety normality information is determined as a safety determination. The unit 460 may output the safety status information transmission unit 480.

  In the first and second embodiments, the dwelling unit control device 200 (200 ′) is described as including the timer counter 420 and the safety determination unit 460. However, the master unit 220 (220 ′) is provided. Also good. In this case, when the safety confirmation signal receiving unit 400 of the dwelling unit control apparatus 200 (200 ′) receives the safety confirmation signal, it says “Safety confirmation is in progress. Press the response button” to the resident in the dwelling unit. A message is notified through the ceiling speaker 160. Further, the response operation detection unit 440 outputs a response operation detection signal to the safety status information transmission unit 480. When the response operation detection signal output from the response operation detection unit 440 is input, the safety status information transmission unit 480 transmits safety status information including safety normal information to the base unit 220 (220 ′).

  On the base unit 220 (220 ′) side, the timer counter 420 calculates the elapsed time from the time when the safety confirmation signal transmission unit 640 outputs the safety confirmation signal to the dwelling unit control device 200 (200 ′) to the current time. The safety determination unit 460 receives the elapsed time information output from the timer counter 420, and before the elapsed time indicated by the elapsed time information exceeds a predetermined time (for example, 5 minutes), the safety status information reception unit. It is determined for each dwelling unit whether or not safety status information including safety normal information is received by 580. If the safety determination unit 460 determines that safety status information including safety normal information is received by the safety status information reception unit 580 before the elapsed time indicated by the elapsed time information exceeds a predetermined time, the safety determination unit 460 outputs the safety normal information and the dwelling unit ID included in the safety status information to setting unit 600. The setting unit 600 sets the value of the safety status information included in the dwelling unit information corresponding to the dwelling unit ID input from the safety determination unit 460 among the dwelling unit information stored in the dwelling unit information storage unit 500 from “under safety confirmation”. Change the setting to “Normal”.

  On the other hand, even if the elapsed time indicated by the elapsed time information output from timer counter 420 exceeds a predetermined time, safety determination unit 460 indicates that safety status information including safety normal information is not received by safety status information reception unit 580. When the determination is made, the safety determination unit 460 outputs the dwell unit ID and the safety abnormality information included in the safety status information to the setting unit 600 ′. The setting unit 600 ′ sets the value of the safety status information included in the dwelling unit information corresponding to the dwelling unit ID input from the safety determination unit 460 among the dwelling unit information stored in the dwelling unit information storage unit 500 from “under safety confirmation”. Change the setting to "abnormal state".

  In the first and second embodiments, the safety status information display unit 620 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and the value of the safety status information is set to “normal state”. Although the example which removes the safety status information of the resident in the dwelling unit corresponding to the dwelling unit ID included in the dwelling unit information from the display target of the safety status information display screen displayed on the display 240 has been described, the present invention is limited to this. Not. For example, the safety status information display unit 620 displays the unit ID included in the dwell unit information in which the value of the safety status information is set to “normal state”, “normal state (absent)”, and “normal state (non-resident)”. A corresponding resident's safety status information value may be set to “* (asterisk)” or the like for mask display. In addition, the safety status information display unit 620 noticed in advance the color of the safety status information of the resident in the dwelling corresponding to the dwelling unit ID included in the dwelling unit information whose safety status information value is set to “normal state”. The color of the safety status information of other residents (that is, the residents whose safety is to be confirmed) may be displayed in a conspicuous red color.

  Further, in the first and second embodiments, the warning unit 660 refers to the dwelling unit information stored in the dwelling unit information storage unit 500, and the value of the safety status information changes from “under safety confirmation” to “abnormal state”. Although the example which outputs the warning sound for warning that the resident in the dwelling unit corresponding to the dwelling unit ID included in the dwelling unit information whose setting is changed from the speaker 260 has been described has been described, The output process is not an essential process. However, it is preferable to perform the process of outputting the warning sound from the speaker 260 in that the dwelling unit in the dwelling unit is abnormally notified to the administrator.

  Further, in the first and second embodiments, when the behavior presence / absence detection unit 300 can detect the movement of the resident or the use of the water, gas, and toilet by the resident, the resident Although an example in which it is determined that there has been an action has been described, the present invention is not limited to this. For example, the behavior presence / absence detection unit 300 is based on a pressing detection signal output from a detection means other than the life cycle sensor 120 (for example, an emergency call button pressed by a resident when making an emergency call from the resident to the manager). Thus, it may be determined that the resident's action has occurred.

  In addition, each of the first and second embodiments described above is merely an example of a specific example for carrying out the present invention, and the technical scope of the present invention should not be interpreted in a limited manner. It will not be. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
