Here, the air conditioner 71 has, for example, as shown in FIG. 2, a human sensor 711 that detects a subject PE1 sleeping on the bed BE1 installed within the detection area A1 in the dwelling unit H1. The human sensor 711 is an object detection device having, for example, a pyroelectric sensor, and has a function of capturing an infrared image using infrared rays emitted from an object (for example, the subject PE1) present within the detection area A1. . Here, the pixel value of each pixel forming an infrared image indicates the relative intensity of infrared rays emitted from an object to be imaged.

The control device 1 includes, for example, as shown in FIG. 3, a CPU (Central Processing Unit) 101, a main memory unit 102, an auxiliary memory unit 103, a communication interface 104, and a bus 109 connecting these to each other. . The main storage unit 102 is a volatile memory such as RAM (Random Access Memory) and is used as a work area for the CPU 101 .

Auxiliary storage unit 103 also has temperature storage unit 131 , monitoring mode storage unit 132 , criterion storage unit 133 , message storage unit 134 , destination storage unit 135 , and state storage unit 136 .

The temperature storage unit 131 stores, for example, information indicating a reference temperature range with respect to the temperature of the heat source calculated from the infrared image captured by the human sensor 711 of the air conditioner 71 . The temperature storage unit 131 stores, for example, information indicating the lower limit temperature and information indicating the upper limit temperature of the reference temperature range of the heat source when determining that the heat source is the target person. Here, the reference temperature range may be set to 31.5°C to 37.5°C, for example, considering that the body surface temperature of a general human body ranges from 32°C to 37°C.

For example, as shown in FIG. 4, the monitoring mode storage unit 132 stores monitoring mode information in association with monitoring target identification information that identifies the states of various devices to be monitored. In the example shown in FIG. 4, the monitoring mode when it is determined that the target person exists in the dwelling unit H1 is the duration of a state in which there is no operation of various devices in the dwelling unit H1, and whether or not there is a sudden environmental change in the dwelling unit H1. , the monitoring mode is set to monitor the presence or absence of abnormal operation or failure of various devices and avoid monitoring the operating state of the devices in the dwelling unit H1. On the other hand, the monitoring mode when it is determined that the target person does not exist in the dwelling unit H1 is the duration of a state in which there is no operation of various devices in the dwelling unit H1, the presence or absence of a sudden environmental change in the dwelling unit H1, and the presence or absence of various devices. A monitoring mode is set in which monitoring of the presence or absence of abnormal operation or failure is avoided and the operating state of the equipment in the dwelling unit H1 is monitored.

For example, as shown in FIG. 5, the determination criterion storage unit 133 stores information acquired from various devices and determination criterion information indicating determination criteria corresponding to the above-described monitoring target identification information. In the example shown in FIG. 5, when the duration ΔT0 of the open state of the door of the refrigerator 75 is equal to or greater than the duration threshold ΔT0th, or the duration ΔT1 of the lighting state of the lighting fixture installed in the toilet or the like is equal to or greater than the duration threshold ΔT1th. In the case of , it is determined that an abnormality has occurred in the dwelling unit H1 or the subject person. In addition, if the refrigerator 75 in continuous operation is stopped, or if the air conditioner 71 is operating even though there is no person in the dwelling unit H1, an abnormality occurs in the dwelling unit H1 or the subject. It is set so that it is determined that there is Furthermore, when the temperature Th2 of the room in which the air conditioner 71 is installed is equal to or higher than a preset temperature upper limit threshold Th2max or equal to or lower than a preset temperature lower limit threshold Th2min, an abnormality has occurred in the dwelling unit H1 or the subject. It is set to be determined as Here, the temperature upper threshold ΔTh2max is set to 30° C., for example. Further, for example, if the temperature Th3 of the room in which the air conditioner 71 is installed is equal to or higher than the temperature threshold Th3th, if the duration ΔT4 of the closed state of the door of the refrigerator 75 is equal to or higher than the duration threshold ΔT4th, or When the total power consumption P5 of various devices is equal to or greater than the power consumption threshold value P5th, it is determined that an abnormality has occurred in the dwelling unit H1 or the subject. Then, it is determined whether or not only the obtained information associated with the monitoring target identification information employed in the set monitoring mode satisfies the determination criteria indicated by the determination criteria information.

Returning to FIG. 3 , the message storage unit 134 stores message information indicating messages to be notified to the terminal device 5 , the cloud server 2 and the servers 3 and 4 . The destination storage unit 135 stores information indicating destinations of the message information, such as IP address information of the terminal device 5, the cloud server 2, and the servers 3 and 4, which are the destinations of the message information. The state storage unit 136 stores the device state information acquired by the device state acquisition unit 112, the power consumption information acquired by the power acquisition unit 113, and the information indicating the determination result by the abnormality determination unit 116 in association with each other.

The detection information acquisition unit 111 acquires, for example, detection information indicating an infrared image captured by a human sensor 711 provided in the air conditioner 71 from the human sensor 711 via the indoor network NT2.

The presence/absence determination unit 114 determines the presence/absence of the target person in a preset area in the dwelling unit H1, for example, in the room where the air conditioner 71 is installed. The presence/absence determination unit 114 determines the presence/absence of the target person in the room based on the detection information output from the human sensor 711 . Specifically, the presence/absence determination unit 114 is based on the temperature of the heat source present in the room obtained from the above-described detection information and the information indicating the reference temperature range for the temperature of the heat source stored in the temperature storage unit 131. , to determine the presence or absence of the target person in the room. Here, the presence/absence determination unit 114 calculates the temperature of the heat source from the intensity of the infrared rays emitted by the heat source indicated by the infrared image information included in the detection information. Moreover, the presence/absence determination unit 114 determines that the target person is present in the room when the temperature of the heat source present in the room is within the reference temperature range for the temperature of the heat source described above. Then, if the presence/absence determination unit 114 determines that the target person does not exist in the room in which the air conditioner 71 is installed in which the target person in the dwelling unit H1 normally stays, it is determined that the target person does not exist in the dwelling unit H1. judge.

The monitoring mode selection unit 115 selects a monitoring mode to be employed from the above-described two types of monitoring modes, for example, based on the presence or absence of a target person in the room in which the air conditioner 71 is installed. When it is determined that the target person exists in the dwelling unit H1, the monitoring mode selection unit 115 refers to the monitoring mode information stored in the monitoring mode storage unit 132, and identifies the monitoring target when it is determined that the target person exists. A combination of information (for example, monitoring target identification information ID1[0], ID[2], ID[3] shown in FIG. 4) is selected. On the other hand, when it is determined that the subject does not exist in the dwelling unit H1, the monitoring mode selection unit 115 refers to the monitoring mode information stored in the monitoring mode storage unit 132, and when it is determined that the subject does not exist. monitoring target identification information (for example, monitoring target identification information ID1[1] shown in FIG. 4). That is, when the presence/absence determination unit 114 determines that the target person is present in the room, the monitoring mode selection unit 115 continues the non-operation state in which there is no operation to close the door of the refrigerator 75 or no operation to turn off the lighting equipment. When the time is equal to or longer than the duration threshold, a monitoring mode is selected in which abnormality occurs in the dwelling unit H1. On the other hand, when the presence/absence determination unit 114 determines that there is no target person in the room, the monitoring mode selection unit 115 selects a non-operation state in which there is no operation to close the door of the refrigerator 75 or no operation to turn off the lighting equipment. Select a monitoring mode that avoids determining the presence or absence of anomalies based on duration.

The device status acquisition unit 112 acquires device status information indicating the status of various devices installed in the dwelling unit H1 based on the selected monitoring mode. When the monitoring mode selection unit 115 selects, for example, a combination of monitoring target identification information ID1[0], ID[2], and ID[3] shown in FIG. Acquisition information associated with the monitoring target identification information ID1[0], ID[2], and ID[3] is acquired by referring to the stored acquisition information. Assume that the acquisition information stored in the criterion storage unit 133 is set as shown in FIG. 5, for example. In this case, the device state acquisition unit 112 acquires information DA0[0] indicating the open/closed state of the door of the refrigerator 75, information DA0[1] indicating the lighting state of the lighting fixture, and the temperature of the room in which the air conditioner 71 is installed. The information DA2[0] to be shown is acquired from the refrigerator 75, the lighting equipment, and the air conditioner 71. On the other hand, when the monitoring target identification information ID1[1] is selected by the monitoring mode selection unit 115, the device state acquisition unit 112 refers to the acquired information stored in the criterion storage unit 133 to determine the operating state of the refrigerator 75. information DA1[0] indicating the operating state of air conditioner 71 and information DA1[1] indicating the operating state of air conditioner 71 are acquired from refrigerator 75 and air conditioner 71.

Returning to FIG. 3, the power acquisition unit 113 acquires power consumption information indicating power consumption in various devices based on the monitoring mode. For example, when the acquisition information stored in the determination criterion storage unit 133 is set as shown in FIG. When the combination of [3] is selected, the power acquisition unit 113 acquires from the power measuring device 8 power consumption information indicating the power consumption of various devices in the dwelling unit H1. On the other hand, when the monitor mode selection unit 115 selects, for example, the monitoring object identification information ID1[1] shown in FIG. Avoid acquisition from device 8.

The abnormality determination unit 116 determines whether an abnormality has occurred in the dwelling unit H1 from the state of the equipment indicated by the equipment status information and the power consumption indicated by the power consumption information based on the preset abnormality determination criteria corresponding to the above-described monitoring mode. determine whether or not Assume that the acquisition information stored in the criterion storage unit 133 is set as shown in FIG. 5, for example. In this case, when the monitor mode selection unit 115 selects a combination of the monitoring target identification information ID1[0], ID[2], and ID[3], the abnormality determination unit 116 determines By referring to the criterion information, it is determined whether or not the criterion indicated by the criterion information DAB0[0], DAB0[1], DAB2[0], DAB2[0], DAB3[1], DAB2[2] is satisfied. do. Specifically, based on information DA0[0] indicating the opened/closed state of the door of refrigerator 75 acquired from refrigerator 75, abnormality determination unit 116 sets duration ΔT0 of the open state of the door of refrigerator 75 in advance. It is determined whether or not the duration ΔT0th is greater than or equal to the duration threshold ΔT0th, and if the duration ΔT0 is greater than or equal to the duration threshold ΔT0th, it is determined that an abnormality has occurred. The duration threshold ΔT0th is set to, for example, about 12 hours. Here, the information DA0[0] indicating the opened/closed state of the door of the refrigerator 75 includes information indicating whether the door is in the open state or the closed state, and open/close count information indicating the cumulative number of open/close times of the door. I'm in. Then, the abnormality determination unit 116 continuously acquires the information DA0[0] indicating that the door is open and indicating that the accumulated number of times of opening/closing indicated by the number of times of opening/closing is constant for the duration threshold ΔT0th or more. If it continues, it is determined that an abnormality has occurred.

Further, based on the information DA0[1] indicating the lighting state of the lighting fixture acquired from the lighting fixture, the abnormality determination unit 116 determines that the duration time ΔT1 of the lighting state of the lighting fixture is equal to or greater than a preset duration threshold value ΔT1th. If the duration ΔT1 is equal to or greater than the duration threshold ΔT1th, it is determined that an abnormality has occurred. Furthermore, based on the information DA2[0] indicating the temperature of the room acquired from the air conditioner 71, the abnormality determination unit 116 determines that the room temperature Th2 is equal to or higher than the preset upper limit temperature threshold Th2max or It is determined whether or not the room temperature Th2 is equal to or lower than the threshold value Th2min, and if the room temperature Th2 is equal to or higher than the temperature upper limit threshold value Th2max or equal to or lower than the preset temperature lower limit threshold value Th2min, it is determined that an abnormality has occurred. Further, based on the information DA0[0] indicating the open/closed state of the door of the refrigerator 75 acquired from the refrigerator 75, the abnormality determination unit 116 determines the duration ΔT4 of the closed state of the door of the refrigerator 75 as a preset duration threshold value. It is determined whether or not the duration ΔT4th is longer than or equal to ΔT4th, and if the duration ΔT4 is longer than or equal to the duration threshold ΔT4th, it is determined that an abnormality has occurred. Furthermore, based on the power consumption information DA3[2] acquired from the power measuring device 8, the abnormality determination unit 116 determines whether the power consumption P5 of various devices in the dwelling unit H1 is equal to or greater than a preset power consumption threshold value P5th. If the power consumption P5 is equal to or greater than the power consumption threshold value P5th, it is determined that an abnormality has occurred.

On the other hand, when the monitoring object identification information ID1[1] is selected by the monitoring mode selection unit 115, the abnormality determination unit 116 refers to the determination criterion information stored in the determination criterion storage unit 133, and determines the determination criterion information DAB1[0]. ] and DAB1[1]. Specifically, abnormality determination unit 116 determines whether refrigerator 75 is stopped based on information DA1[0] indicating the operating state of refrigerator 75 acquired from refrigerator 75, and determines whether refrigerator 75 is stopped. If so, it is determined that an abnormality has occurred. Further, the abnormality determination unit 116 determines whether the air conditioner 71 is operating based on the information DA1[1] indicating the operating state of the air conditioner 71 acquired from the air conditioner 71, and determines whether the air conditioner 71 is operating. If the machine 71 is operating, it is determined that an abnormality has occurred.

Returning to FIG. 3, when the abnormality determination unit 116 determines that an abnormality has occurred, the message generation unit 117 generates message information indicating a message notifying that an abnormality has occurred in the dwelling unit H1. do. The message generation unit 117 causes the message storage unit 134 to store the generated message. The message transmitting unit 118 acquires message information from the message storage unit 134, acquires destination information of the message information from the destination storage unit 135, and transmits the acquired message information to the destination indicated by the acquired destination information. Send. The state recording unit 119 associates the device state information acquired by the device state acquisition unit 112, the power consumption information acquired by the power acquisition unit 113, and the information indicating the determination result by the abnormality determination unit 116 with each other and stores them in the state storage unit 136. Memorize. The timer unit 120 compares the current time with a preset monitoring time for the dwelling unit H1, and determines whether or not the monitoring time has arrived.

Next, a monitoring process executed by the control device 1 according to this embodiment will be described with reference to FIG. This monitoring process is started, for example, when the control device 1 is powered on. First, the timer 120 determines whether or not a preset monitoring time has come (step S101). The monitoring timing is set so as to come at regular time intervals, for example, between 1 minute and 10 minutes. As long as the timer unit 120 determines that the monitoring time has not yet come (step S101: No), the process of step S101 is repeatedly executed. On the other hand, when the clock unit 120 determines that the monitoring time has come (step S101: Yes), the detection information acquisition unit 111 acquires detection information from the human sensor 711 (step S102). This detection information includes information indicating an infrared image GA1 as shown in FIG. 7, for example. When a heat source exists in the detection area A1 of the human sensor 711, the infrared image GA1 becomes an image including the image AP1 of the heat source.

Returning to FIG. 6, next, the presence/absence determining unit 114 determines whether or not there is a heat source in the room based on the acquired detection information (step S103). When the presence/absence determination unit 114 determines that there is no heat source in the room (step S103: No), it determines that the subject person does not exist in the dwelling unit H1 (step S104), and the process of step S108, which will be described later, is executed. . On the other hand, when the presence/absence determination unit 114 determines that there is a heat source in the room (step S103: Yes), it calculates the temperature of the heat source from the intensity of the infrared rays emitted by the heat source indicated by the infrared image information included in the detection information ( step S105). Next, based on the calculated heat source temperature and the information indicating the reference temperature range for the heat source temperature stored in the temperature storage unit 131, the presence/absence determination unit 114 determines that the heat source temperature Thh is the lower limit temperature of the reference temperature range. It is determined whether or not the temperature is equal to or higher than Thhmin and equal to or lower than the upper limit temperature Thhmax of the reference temperature range (step S106). When the presence/absence determination unit 114 determines that the temperature Thh of the heat source is outside the reference temperature range (step S106: No), the process of step S104 described above is executed.

On the other hand, if the presence/absence determining unit 114 determines that the temperature Thh of the heat source is equal to or higher than the lower limit temperature Thhmin and equal to or lower than the upper limit temperature Thhmax (step S106: Yes), it determines that the subject exists in the dwelling unit H1 (step S107 ).

After that, the monitoring mode selection unit 115 selects a monitoring mode to be adopted from among the above-described two types of monitoring modes according to the presence/absence of the subject (step S108). Next, the device state acquisition unit 112 acquires device state information indicating the state of various devices installed in the dwelling unit H1 based on the selected monitoring mode, and the power acquisition unit 113 acquires the selected monitoring mode. power consumption information indicating the power consumption of each device is acquired (step S109). Here, the power acquisition unit 113 avoids acquiring the power consumption information when the monitoring mode corresponding to the case where it is determined that the target person does not exist in the dwelling unit H1 is selected.

Next, the abnormality determination unit 116 determines the power consumption indicated by the power consumption information and the state of the device indicated by the device state information based on the preset abnormality determination criteria corresponding to the above-described monitoring mode. It is determined whether or not an abnormality has occurred (step S110). When the abnormality determination unit 116 determines that an abnormality has not occurred in the dwelling unit H1 (step S110: No), the process of step S113, which will be described later, is executed. On the other hand, when the abnormality determination unit 116 determines that an abnormality has occurred in the dwelling unit H1 (step S110: Yes), the message generation unit 117 generates a message notifying that an abnormality has occurred in the dwelling unit H1. is generated (step S111). Subsequently, the message transmission unit 118 transmits the message information generated by the message generation unit 117 to the destination indicated by the destination information stored in the destination storage unit 135 (step S112). After that, the state recording unit 119 associates the device state information acquired by the device state acquisition unit 112, the power consumption information acquired by the power acquisition unit 113, and the information indicating the determination result by the abnormality determination unit 116 with each other, and stores them in the state storage unit. 136 (step S113), the process of step S101 is executed again. Here, when the power acquisition unit 113 avoids acquiring the power consumption information, the state recording unit 119 avoids storing the power consumption information in the state storage unit 136 .

As described above, according to the control device 1 according to the present embodiment, the monitoring mode selection unit 115 selects a monitoring mode to be adopted from two types of monitoring modes based on the presence or absence of the target person in the dwelling unit H1. do. In addition, the device state acquisition unit 112 acquires device state information indicating the state of various devices installed in the dwelling unit H1 based on the selected monitoring mode, and the power acquisition unit 113 selects the selected monitoring mode. Based on this, power consumption information indicating the power consumption of each device is acquired. Then, the abnormality determination unit 116 determines whether or not an abnormality has occurred in the dwelling unit H1 from the states of the various devices and the power consumption of the various devices based on the abnormality determination criteria corresponding to the selected monitoring mode. do. Thereby, a subject's state can be determined with sufficient accuracy, considering the subject's presence or absence in the dwelling unit H1.

Further, when the presence/absence determination unit 114 determines that the target person is present in the room, the monitoring mode selection unit 115 according to the present embodiment does not perform the operation of closing the door of the refrigerator 75 or the operation of turning off the lighting equipment. If the duration of the non-operating state is equal to or longer than the duration threshold, a monitoring mode corresponding to the determination criterion that abnormality has occurred in the dwelling unit H1 is selected. On the other hand, when the presence/absence determination unit 114 determines that there is no target person in the room, the monitoring mode selection unit 115 selects a non-operation state in which there is no operation to close the door of the refrigerator 75 or no operation to turn off the lighting equipment. Select a monitoring mode that avoids determining the presence or absence of anomalies based on duration. As a result, it is possible to suppress an erroneous determination as to whether or not an abnormality has occurred when there is no target person in the dwelling unit H1.

(Embodiment 2)
The control device according to the present embodiment employs a person to be monitored, a person not to be monitored, and a target animal to be monitored, such as a pet, depending on whether or not they are present in the area. It differs from the control device 1 according to the first embodiment in that the monitoring mode is changed.

For example, as shown in FIG. 8, the control device 2001 according to the present embodiment includes a CPU 101, a main storage unit 102, an auxiliary storage unit 103, a communication interface 104, and a bus 109 that connects these to each other. . In addition, in FIG. 8, the same reference numerals as in FIG. 3 denote the same configurations as in the first embodiment. The CPU 101 reads the program stored in the auxiliary storage unit 103 into the main storage unit 102 and executes it, thereby obtaining the detection information acquisition unit 111, the device status acquisition unit 112, the power acquisition unit 113, the presence/absence determination unit 2114, and the monitoring mode selection unit. 2115 , abnormality determination unit 2116 , message generation unit 117 , message transmission unit 118 , state recording unit 119 and timer unit 120 . In addition, the auxiliary storage unit 103 has a heat source information storage unit 2131, a monitoring mode storage unit 2132, a criterion storage unit 2133, a message storage unit 134, a destination storage unit 2135, and a state storage unit 136. .

The heat source information storage unit 2131 stores information indicating the lower limit temperature and upper limit temperature of the reference temperature range with respect to the temperature of the heat source when it is determined that the heat source is a person, as well as when the heat source is an elderly person and when it is not an elderly person. It stores information indicating a reference temperature for distinguishing between a person and a person. Here, the reference temperature range is, for example, 31.0°C, considering that the body surface temperature of a general human body is 32°C to 37°C, and that the temperature of a small dog is 1°C to 2°C higher than that of the human body. It may be set in the range of 5°C to 39.5°C. Also, the reference temperature may be set to 36.8 degrees, for example, considering that the average body temperature of infants or children is about 37 degrees Celsius. Further, the heat source information storage unit 2131 stores a reference area range for distinguishing whether the heat source is a person or a pet from the area of the image of the heat source included in the infrared image indicated by the detection information acquired from the human sensor 711. and the reference movement amount for the movement amount of the heat source within a preset period. Here, the preset period may be set to, for example, 5 minutes to 10 minutes, and the reference movement amount may be set to, for example, 1 m.

For example, as shown in FIG. 9, the monitoring mode storage unit 2132 stores information such as when there is a person other than an elderly person in the dwelling unit H1, when there is an elderly person who is a target person, when there is a pet as a target animal, and when a pet is present in the dwelling unit H1. Store monitoring mode information corresponding to the case where there is no person or pet in H1. In the example shown in FIG. 9, the monitoring mode when it is determined that there is a person other than the elderly in the dwelling unit H1 monitors the presence or absence of abnormal operation or failure of various devices, and the operation of various devices in the dwelling unit H1 is performed. A monitoring mode is set to avoid monitoring the duration of a non-operating state, the operating state of the equipment in the dwelling unit H1, and the presence or absence of a sudden change in the environment within the dwelling unit H1. In addition, the monitoring mode when it is determined that an elderly person who is a target person exists in the dwelling unit H1 is the duration of a non-operation state in which various devices in the dwelling unit H1 are not operated, the operating state of the devices in the dwelling unit H1, A monitoring mode is set to monitor the presence or absence of sudden environmental changes in the dwelling unit H1 and the presence or absence of abnormal operation or failure of various devices. Furthermore, the monitoring mode when it is determined that a pet exists in the dwelling unit H1 monitors the operating state of the equipment in the dwelling unit H1, the presence or absence of sudden environmental changes in the dwelling unit H1, and the presence or absence of abnormal operation or failure of various devices. A monitoring mode is set to avoid monitoring the duration of a non-operating state in which various devices in the dwelling unit H1 are not operated. However, the method of monitoring the operating state of the equipment in the dwelling unit H1 in this case is different from the monitoring mode when it is determined that the target elderly person is present in the dwelling unit H1. In addition, the monitoring mode when it is determined that neither people nor pets exist in the dwelling unit H1 is the duration of a non-operation state in which various devices in the dwelling unit H1 are not operated, the presence or absence of a sudden environmental change in the dwelling unit H1, and the A monitoring mode is set to avoid monitoring the presence or absence of abnormal operation or failure of various devices and to monitor the operating state of the devices in the dwelling unit H1. The method of monitoring the operating state of the devices in the dwelling unit H1 in this case is the same as the monitoring mode when it is determined that there is a pet in the dwelling unit H1.

For example, as shown in FIG. 10, the determination criterion storage unit 2133 stores information acquired from various devices and determination criterion information indicating determination criteria corresponding to the above-described monitoring target identification information. In the example shown in FIG. 10, the duration of the non-operation state in which various devices in the dwelling unit H1 are not operated, the operating state of the devices, the presence or absence of a sudden environmental change, and the device If the refrigerator 75 in continuous operation is stopped, or if the air conditioner 71 is stopped, an abnormality occurs in the dwelling unit H1 or the subject. Criterion information for determining that the Then, as in the first embodiment, it is determined whether or not only the obtained information associated with the monitoring target identification information employed in the set monitoring mode satisfies the criteria indicated by the criteria information.

For example, as shown in FIG. 11, the transmission destination storage unit 135 stores transmission destination information indicating the transmission destination in association with each determination result by the presence/absence determination unit 2114 . In the example shown in FIG. 11, when the presence/absence determination unit 2114 determines that a person other than the elderly exists in the dwelling unit H1, the message information is transmitted to the terminal device 5 and the cloud server 2, and the presence/absence determination unit 2114 When it is determined that the target elderly person is present in H1, the message information is set to be transmitted to the server 3 installed in the housing management company and the server 4 installed in the facility of the public institution. there is Further, when the presence/absence determination unit 2114 determines that a pet exists in the dwelling unit H1, the message information is transmitted only to the server 4 of the public institution, and the presence/absence determination unit 2114 determines that neither a person nor a pet exists in the dwelling unit H1. If determined, the message information is set to be transmitted to the terminal device 5, the server 3 installed in the housing management company, and the cloud server 2. FIG.

The presence/absence determination unit 2114 acquires the information indicating the reference temperature range, the information indicating the reference temperature, the information indicating the reference area range, and the information indicating the reference movement amount, which are stored in the heat source information storage unit 2131 . Then, the presence/absence determination unit 2114, based on the temperature of the heat source, the area of the heat source, and the movement amount of the heat source obtained from the above-described detection information, and the information obtained from the heat source information storage unit 2131, The existence or non-existence of a person, an elderly person who is a target person, or a pet which is a target animal is determined. The presence/absence determining unit 2114 associates the position of the heat source with the monitoring period and stores it in the state storage unit 136 for each monitoring period, and calculates the amount of movement of the heat source from the previous monitoring period for each monitoring period. Then, the presence/absence determination unit 2114 determines whether or not the cumulative amount of movement of the heat source within a preset period is equal to or greater than the reference amount of movement. Here, the presence/absence determining unit 2114 determines that the temperature of the heat source present in the room is within the reference temperature range for the temperature of the heat source described above, the area of the heat source is within the reference area range, and the temperature of the heat source is equal to or lower than the reference temperature. and the amount of movement of the heat source within the preset period is less than the reference amount of movement, it is determined that the subject is present in the room. If the temperature of the heat source is within the reference temperature range and the area of the heat source is outside the reference area range, the presence/absence determination unit 2114 determines that the pet is present in the room. Furthermore, the presence/absence determination unit 2114 determines whether the temperature of the heat source is within the reference temperature range, the area of the heat source is within the reference area range, and the temperature of the heat source is higher than the reference temperature, or the temperature of the heat source is the reference temperature. If the temperature is below the temperature and the movement amount of the heat source is equal to or above the reference movement amount, it is determined that there is a person other than the elderly in the room.

The monitoring mode selection unit 2115 selects one of the above-described four types of monitoring modes based on, for example, the presence or absence of a person other than an elderly person in the room where the air conditioner 71 is installed, an elderly person who is a target person, or a pet. Select the monitoring mode to use.

The abnormality determination unit 2116 determines whether an abnormality has occurred in the dwelling unit H1 from the state of the equipment indicated by the equipment status information and the power consumption indicated by the power consumption information based on the preset abnormality determination criteria corresponding to the monitoring mode. determine whether or not Assume that the acquisition information stored in the criterion storage unit 2133 is set as shown in FIG. 10, for example. In this case, when the monitor mode selection unit 2115 selects a combination of the monitoring target identification information ID1[0], ID[2], ID[3], and ID[4], the abnormality determination unit 2116 stores the determination criterion storage unit 2133 is stored, and based on the information DA1[0] indicating the operation state of the refrigerator 75 acquired from the refrigerator 75, it is determined whether or not the refrigerator 75 is stopped, and the refrigerator 75 is stopped. If so, it is determined that an abnormality has occurred. Further, the abnormality determination unit 2116 determines whether or not the air conditioner 71 is stopped based on the information DA1[1] indicating the operating state of the air conditioner 71 acquired from the air conditioner 71. If the machine 71 is stopped, it is determined that an abnormality has occurred.

Next, monitoring processing executed by the control device 1 according to the present embodiment will be described with reference to FIGS. 12 to 14. FIG. First, a series of processes from steps S201 to S203 are executed. The contents of the processing from steps S201 to S203 are the same as the processing from steps S101 to S103 described in the first embodiment. In step S203, if the presence/absence determination unit 2114 determines that there is no heat source in the room (step S203: No), it determines that there are no people or pets in the room (step S204), and performs the process of step S213 described later. is executed. On the other hand, when the presence/absence determining unit 2114 determines that there is a heat source in the room (step S203: Yes), it calculates the temperature of the heat source in the same manner as in the first embodiment (step S205). Subsequently, the presence/absence determining unit 2114 determines whether or not the temperature Thh of the heat source is equal to or higher than the lower limit temperature Thhmin of the reference range and lower than or equal to the upper limit temperature Thhmax of the reference range in the same manner as in the first embodiment (step S206). ). When the presence/absence determination unit 2114 determines that the temperature Thh of the heat source is outside the reference temperature range (step S206: No), the process of step S204 described above is executed.

It is determined whether or not it is equal to or larger than Smin and equal to or smaller than the upper limit area Smax of the reference area range (step S207). When the presence/absence determination unit 2114 determines that the area S of the heat source is outside the reference area range (step S207: No), it determines that a pet exists in the room (step S208). For example, when a pet exists in the detection area A1 of the human sensor 711, an infrared image GA2 as shown in FIG. 13 is obtained. This infrared image GA2 is an image including an image AP2 of the pet that is the heat source. Here, the area of the image AP2 is an area corresponding to 9 pixels. On the other hand, when the subject exists in the detection area A1 of the human sensor 711, an infrared image GA1 as shown in FIG. be. In this case, the lower limit area Smin is set to an area corresponding to, for example, 25 pixels, and the upper limit area Smax is set to an area corresponding to, for example, 35 pixels.

Returning to FIG. 12, the process of step S213, which will be described later, is then executed. On the other hand, if the presence/absence determination unit 2114 determines that the area S of the heat source is equal to or larger than the lower limit area Smin and equal to or smaller than the upper limit area Smax of the reference area range (step S207: Yes), the temperature of the heat source is equal to or higher than the reference temperature Thhth. It is determined whether or not there is (step S209). When the presence/absence determining unit 2114 determines that the temperature of the heat source is equal to or higher than the reference temperature Thhth (step S209: Yes), it determines that a person other than the elderly exists in the room (step S210). Next, the process of step S213, which will be described later, is executed. On the other hand, when the presence/absence determination unit 2114 determines that the temperature of the heat source is lower than the reference temperature Thhth (step S209: No), it determines whether the movement amount DM of the heat source within the preset period is equal to or greater than the reference movement amount DMth. (step S211). When the presence/absence determination unit 2114 determines that the movement amount DM of the heat source is equal to or greater than the reference movement amount DMth (step S211: Yes), it determines that a person other than the elderly exists in the room (step S210). On the other hand, when the presence/absence determination unit 2114 determines that the movement amount DM of the heat source is less than the reference movement amount DMth (step S211: No), it determines that the target elderly person is present in the room (step S212).

Subsequently, the monitoring mode selection unit 2115 selects a monitoring mode to be adopted from among the above-described four types of monitoring modes according to the presence/absence of the subject (step S213). Next, the device state acquisition unit 112 acquires device state information indicating the state of various devices installed in the dwelling unit H1 based on the selected monitoring mode, and the power acquisition unit 113 acquires the selected monitoring mode. power consumption information indicating the power consumption of each device is acquired (step S214).

After that, the abnormality determination unit 2116 determines whether there is an abnormality in the dwelling unit H1 from the state of the equipment indicated by the equipment status information and the power consumption indicated by the power consumption information based on the preset abnormality determination criteria corresponding to the monitoring mode. is occurring (step S215). When the abnormality determination unit 2116 determines that no abnormality has occurred in the dwelling unit H1 (step S215: No), the process of step S219, which will be described later, is executed. On the other hand, when the abnormality determination unit 2116 determines that an abnormality has occurred in the dwelling unit H1 (step S215: Yes), the message generation unit 117 generates the aforementioned message information (step S216). Subsequently, the message transmitting unit 118 selects destination information according to the determination result of the presence/absence determination unit 2114 from among the destination information stored in the destination storage unit 2135 (step S217). After that, the message transmitting unit 118 transmits the message information generated by the message generating unit 117 to the destination indicated by the selected destination information (step S218). After that, the state recording unit 119 associates the device state information acquired by the device state acquisition unit 112, the power consumption information acquired by the power acquisition unit 113, and the information indicating the determination result by the abnormality determination unit 2116 with each other, and stores them in the state storage unit. 136 (step S219), the process of step S201 is executed again.

As described above, in the control device 2001 according to the present embodiment, the presence/absence determination unit 2114 determines whether there is an object in the dwelling unit H1 obtained from the detection information output from the human sensor 711 that detects an object present in the dwelling unit H1. Based on the temperature, size, and amount of movement of the existing object, it is determined whether or not there is a person other than the elderly, an elderly person who is the target person, or a pet which is the target animal in the dwelling unit H1. Thereby, the monitoring mode can be finely changed according to the existence or non-existence of persons other than elderly people, elderly people, and pets in the dwelling unit H1. Therefore, monitoring suitable for the situation in the dwelling unit H1 can be implemented.

In addition, the message transmission unit 118 according to the present embodiment, according to the presence or absence of people other than elderly people, elderly people, and pets in the dwelling unit H1 determined by the presence/absence determination unit 2114, the message generated by the message generation unit 117 Send information to a preset destination.
