Therefore, it is possible to improve the convenience of the operation of changing the role of the motion sensor in the facility staff.

Further, when the information device determines that a person is making a suspicious movement, the information device identifies the information that the person is making a suspicious movement and the air conditioner that has transmitted the person detection signal regarding the detection of the person. The available information may be transmitted to one or more information terminals.

According to this configuration, facility staff, etc. use an information terminal, for example, a smartphone, tablet, personal computer, etc., to provide information on a person's suspicious movement and information on the room in which the person lives. And can be obtained. Therefore, facility staff and the like can quickly deal with the suspicious movement.

Further, the plurality of air conditioners are installed in the same facility and include a locking device that automatically locks one or more input / output ports for input / output to the facility, and the information device is suspicious of a person. When the movement is determined, the locking device is controlled by the information device to lock the one or more input / output ports, and if a predetermined operation is not performed, a person in the facility moves from the input / output port to the outside. You may not be able to go out.

According to this configuration, it is possible to prevent a person who is suspiciously moving from going out of the facility. Thus, for example, it is possible to prevent a person suffering from dementia from being able to go out of the facility and go missing.

Further, the information device determines whether or not the person has returned to the room within a predetermined time after leaving the room based on the person detection signal, and the person returns to the room within the predetermined time. If it recognizes that it has not returned, it may be determined that the person is making suspicious movements.

According to this configuration, it is possible to easily and accurately determine that a person who has left the room may be wandering in the facility with simple control.

Further, the plurality of air conditioners are installed in the same facility having one or more entrances and exits, and include one or more common space installation sensors arranged at positions capable of monitoring the common space in the facility, and the information. Based on the person detection signal and the signal from at least one of the common space installation sensors, the device determines whether or not a person has left the room and then passed through any of the entrances and exits closer to the doorway than the room. When the information device recognizes that a person has left the room and then passed through a part closer to the doorway than the room with respect to any one of the rooms, the person moves suspiciously. You may judge that you are doing.

According to this configuration, it is possible to accurately determine that a person who has left the room may go out of the facility.

Further, the person monitoring method according to the present disclosure is a plurality of air conditioners for harmonizing air, and the plurality of air including a motion sensor capable of detecting the presence or absence of a person in each air conditioner. A step of transmitting human detection information indicating that the motion sensor has detected a person from the motion sensor in the harmonizer to an information device in which a portion included in the air conditioner does not exist, and the information device A step of determining whether or not a person is suspiciously moving based on the person detection signal is included.

According to the present disclosure, it is possible to monitor suspicious movements of a person at low cost while considering the privacy of the resident in the facility, and it is possible to reduce the burden on the facility staff to deal with the wandering of the resident.

It is assumed that the driving of the air conditioner 6 is not prohibited, and the air conditioner 6 has not stopped the air conditioning function. The state in which the drive of the compressor is prohibited may be defined as the state in which the current supply to the compressor is prohibited and the compressor cannot be driven. Alternatively, the state in which the driving of the compressor is prohibited means that the air conditioning function of a person using an operation unit (for example, the operation unit of the remote controller of the air conditioner, the operation unit of the operation panel of the air conditioner, etc.) is used. It may be defined as a state in which the air conditioner is unable to perform air conditioning due to the off operation. The operation when the motion sensor 60 is set to the monitoring mode will be described in detail later.

Although not described in detail, the energy saving control may be performed according to the illuminance level detected by the illuminance sensor 61. For example, the air conditioner may be used when the illuminance sensor 61 detects a low illuminance level at bedtime at night. The set temperature of 6 may be changed to a predetermined temperature that can realize energy saving.

Determine if it has been detected.

If a negative determination is made in step S12, the process proceeds to step S13, and the suspicious motion determination unit 170a determines whether or not a person has entered the room 40. When the suspicious motion determination unit 170a identifies that the number of people detected by at least one motion sensor 60 has increased based on the signal from at least one motion sensor 60, a person enters the room 40. You may determine that you have entered.

If an affirmative decision is made in step S13, step S11 is repeated. On the other hand, if a negative determination is made in step S13, the process proceeds to step S14, and the suspicious operation determination unit 170a determines whether or not a predetermined time has elapsed since the person came out based on the information from the timer 76. If a negative determination is made in step S14, step S12 and subsequent steps are repeated.

On the other hand, if an affirmative determination is made in step S12 or step S14, the process proceeds to step S15. In step S15, the central monitoring device 105 transmits information that a person is performing a suspicious operation and information that can identify the room in which the person sleeps to one or more information terminals 35 via the transmission unit 73. Subsequently, in step S16, the central monitoring device 105 transmits a signal for locking one or more doorways to the locking device 7, and as a result, one or more doorways are locked.

When performing step S15, the suspicious operation notification signal generation unit 70b generates a suspicious operation notification signal including information on a person performing the suspicious operation and information capable of identifying the room in which the person sleeps. Further, when performing step S16, the lock signal generation unit 70c generates a lock signal indicating that one or more entrances and exits are locked.

In step S17 after step S16, it is determined whether or not the central monitoring device 105 has received an unlocking signal for unlocking one or more entrances and exits. Such an unlocking signal may be input by a person using at least one of an operation unit 72, an operation panel 45, and an information terminal 35. If a negative determination is made in step S17, steps S17 and subsequent steps are repeated. On the other hand, if an affirmative determination is made in step S17, the locking device 7 unlocks one or more entrances and exits in step S18, the control becomes a return, and steps S11 and subsequent steps are repeated.

This control ends when the mode of all motion sensors 60 is changed to the air conditioning mode and all the motion sensors 160 for common space are not driven (off). Further, the motion sensor 160 for common space of 1 or more may be a motion sensor that constantly monitors the intrusion of a suspicious person into the facility. In this case, the motion sensor 160 for common space is all motion sensors 60. Mode may be changed to air conditioning mode or not turned off.

In this control, for example, the central monitoring device 105 releases a person from the room after the person leaves the room based on the person detection signal from the motion sensor 60 and the signal from at least one motion sensor 160 for a common space. Can also determine whether or not it has passed a place near any of the doorways. Then, when the central monitoring device 105 recognizes that the person has passed a place closer to one of the doorways than the room after leaving the room, it can be determined that the person is suspiciously moving. ..
