The management device 200 is, for example, a device installed in a management company to manage the state of the residence 10, and when it is determined that the room 20 is in an abnormal state or the room temperature is abnormal. In this case, a determination result indicating that the room 20 is in an abnormal state or the room temperature is abnormal is received from the abnormality determination device 100A. The management device 200 that has received such determination results prompts employees, security guards, etc., to check the status of the residence 10 by voice, etc., and transfers the determination results to the portable terminal 300 possessed by the resident's family, relatives, etc. .

The mobile terminal 300 is a terminal owned by an employee of a management company, a resident's family, or the like, such as a smart phone or a tablet terminal. The mobile terminal 300 directly receives the determination result indicating that the room 20 is in an abnormal state or the room temperature is abnormal from the abnormality determination device 100</b>A, or receives the determination result via the management device 200 . When such a determination result is received, an employee of the management company who has the portable terminal 300, a family member, or the like can go to the residence 10 and check the status of the resident.

Although FIG. 1 shows a configuration in which one management device 200 and one mobile terminal 300 are connected, the number of connected management devices and mobile terminals is arbitrary, and two or more management devices 200 and mobile terminals can be connected. 300 may be connected.

Next, the hardware configuration of the abnormality determination device 100A will be described. FIG. 2 is a diagram showing an example of the hardware configuration of the abnormality determination device 100A according to the first embodiment. As shown in FIG. 2, the abnormality determination device 100A includes a control device such as a CPU (Central Processing Unit) 50, a storage device such as a ROM (Read Only Memory) 52 and a RAM (Random Access Memory) 54, and a network 30.

In the abnormality determination device 100A, the CPU 50 executes the control program stored in the ROM 52 to function as the signal reception unit 112, the recording control unit 114, the abnormality determination unit 116, and the communication unit 118 as shown in FIG. .

Next, the functional configuration of the abnormality determination device 100A will be described. FIG. 3 is a functional configuration diagram of the abnormality determination device 100A according to the first embodiment. As shown in FIG. 3, abnormality determination device 100A of the present embodiment includes ammonia sensor 102, temperature sensor 104, and device main body 110. Device main body 110 includes storage unit 150A and signal reception unit 112. , a recording control unit 114 , an abnormality determination unit 116 , and a communication unit 118 .

The ammonia sensor 102 is installed in the room 20 of the dwelling 10 , detects the concentration of ammonia in the room 20 at a predetermined time, and sends a detection signal to the apparatus body 110 . Ammonia is lighter than air, and ammonia generated in the room 20 rises toward the ceiling.

In the present embodiment, an example in which the ammonia sensor 102 is installed on the ceiling of the room 20 is shown. 20 may be mounted on the wall, placed on a shelf or on the floor. Therefore, if a mountable ammonia sensor is used, for example, a visiting caregiver who visits the residence 10, a staff member of a child guidance center, or the like can easily mount the sensor on a shelf or on the floor after obtaining permission from the resident. can do.

The temperature sensor 104 is a sensor that is installed in the room 20 of the residence 10 , detects the temperature in the room 20 at a predetermined time, and sends a detection signal to the device body 110 . The temperature sensor 104 of this embodiment is installed on the ceiling of the room 20 in order to match the detection conditions with the ammonia sensor 102 . Note that the temperature sensor 104 may also be installed anywhere in the room 20 in the same manner.

The storage unit 150A stores detection recording information in which the concentration of ammonia detected by the ammonia sensor 102 and the temperature detected by the temperature sensor 104 are recorded, and is realized by the ROM 522 and the HDD 58 (see FIG. 2). be.

FIG. 4 is a diagram showing an example of detection record information. As shown in FIG. 4, storage unit 150A of the present embodiment stores the detection date of detection of ammonia concentration and temperature, the detection time, the detected temperature (° C.), and the detected ammonia concentration (ppm). , and saves record detection record information associated with .

Referring to the detection record information shown in FIG. The temperature in the room 20 detected at 00 is 24° C. and the ammonia concentration is 0.4 ppm. From this, it can be seen that the temperature in the room 20 increased by 2° C. and the ammonia concentration increased by 0.2 ppm at 14:00 after 8 hours from 6:00. Further, the temperature in the room 20 detected at 22:00 on the same day is 22° C., and the ammonia concentration is 0.2 ppm. As a result, at 22:00 after 8 hours, the temperature in the room 20 decreased by 2° C., and the ammonia concentration decreased by 0.2 ppm.

The signal reception unit 112 receives an ammonia concentration detection signal sent from the ammonia sensor 102 and a temperature detection signal sent from the temperature sensor 104 .

When signal receiving unit 112 receives the detection signal, recording control unit 114 stores the ammonia concentration and temperature obtained from the received detection signal in storage unit 150A in association with the detection date and detection time (detection date and time). recorded in the detected detection record information.

Based on the concentration of ammonia detected by the ammonia sensor 102, the abnormality determination unit 116 determines whether or not the room 20 is in an abnormal state indicating that the room 20 is contaminated. Further, based on the temperature detected by the temperature sensor 104, the abnormality determination unit 116 determines whether the temperature in the room 20 is an abnormal room temperature that is not suitable for living.

Specifically, abnormality determination unit 116 refers to the detection record information stored in storage unit 150A, and determines whether the ammonia concentration detected at a predetermined time has continued to increase for a predetermined number of days. judge. Then, if the detected ammonia concentration does not continue to rise for a predetermined number of days, the abnormality determination unit 116 determines that the room 20 is in a normal state indicating a state in which it is possible to live.

On the other hand, if the detected ammonia concentration continues to rise for a predetermined number of days, the abnormality determination unit 116 determines that the room 20 is in an abnormal state of being contaminated with excrement, putrefaction, or the like. If it is determined to be in an abnormal state, it indicates that the amount of ammonia in the room 20 is increasing, and it can be grasped that the contamination makes life difficult or that the contamination may make life difficult.

For example, referring to the detection record information shown in FIG. 4, the ammonia concentration at 10:00 is acquired for seven days, and the acquired ammonia concentration for seven days is compared to determine whether it continues to rise. For example, if the ammonia concentration on the first day is 0.2 ppm, and after that it rises and falls to 0.2 to 0.4 ppm, it is determined that the room 20 is in a normal state. On the other hand, the ammonia concentration on the first day was 0.2 ppm, but when it was 0.3 ppm, 0.4 ppm, 0.6 ppm, 0.7 ppm, 0.9 ppm, and 1.1 ppm, it increased for 7 days. Since it continues, it is determined that the room 20 is in an abnormal state.

In addition, abnormality determination unit 116 refers to the detection record information stored in storage unit 150A, and the detected indoor temperature is within the temperature range suitable for living until a predetermined time elapses. It is determined whether or not it is out of the range of life suitable temperature shown. Then, when the detected temperature of the room 20 is within the range of the temperature suitable for living until the predetermined time elapses, the abnormality determination unit 116 determines that the temperature of the room 20 is the normal room temperature. .

On the other hand, if the detected temperature in the room 20 is outside the range of suitable temperature for living until the predetermined time elapses, the abnormality determination unit 116 determines that the temperature in the room 20 is an abnormal room temperature that is not suitable for living. It is determined that If the temperature range suitable for daily living can be set and changed according to the season, the age and circumstances of the occupants, and so on, the abnormal state of the room can be determined with higher accuracy. be able to.

For example, if the life-suitable temperature is set to 10° C. to 28° C., the detection record information as shown in FIG. It is determined whether or not it is outside the range of The temperature detected was 22°C at 6:00, and the temperatures detected every 4 hours after that were 23°C and 24°C. Therefore, it is determined that the temperature in the room 20 is normal room temperature. On the other hand, if the detected temperature is 29°C at 6:00 and the temperatures detected every 4 hours after that are 32°C and 36°C, until 8 hours have passed, , the temperature in the room 20 is determined to be an abnormal room temperature.

The communication unit 118 transmits and receives predetermined information to and from the management device 200 and the mobile terminal 300 via the network 30, and is an example of a transmission unit. In the present embodiment, when the abnormality determination unit 116 determines that the ammonia concentration in the room 20 is normal and the temperature in the room 20 is normal room temperature, the communication unit 118 transmits nothing, or Alternatively, the determination result indicating that the room 20 is in a normal state and has a normal room temperature is transmitted to the management device 200 or the like. Further, when the abnormality determination unit 116 determines that the room 20 is in an abnormal state but not in an abnormal room temperature (normal room temperature), the communication unit 118 determines that the room 20 is in an abnormal state. to the management device 200 or the like.

When the abnormality determination unit 116 determines that the room 20 is not in an abnormal state (is in a normal state) but has an abnormal room temperature, the communication unit 118 determines that the room 20 is in an abnormal room temperature. to the management device 200 or the like. Further, when the abnormality determination unit 116 determines that the room 20 is in an abnormal state and has an abnormal room temperature, the communication unit 118 notifies the management device 20 or the like of the determination result that the room 20 is in an abnormal state and has an abnormal room temperature. Send to

Next, the abnormality determination processing by the abnormality determination device 100A will be described. FIG. 5 is a flow chart showing the flow of abnormality determination processing by the abnormality determination device 100A of the first embodiment.

First, at a predetermined time, the ammonia sensor 102 detects the concentration of ammonia in the room 20 (step S100), the temperature sensor 104 detects the temperature in the room 20 (step S102), and the detected detection signals It is delivered to the main body 110 .

Next, the signal receiving unit 112 receives the ammonia concentration detection signal sent from the ammonia sensor 102 and the temperature detection signal sent from the temperature sensor 104 (step S104). Then, recording control unit 114 associates the ammonia concentration and temperature obtained from the detection signal received by signal receiving unit 112 with the detection date and detection time (detection date and time), and stores detection record information in storage unit 150A. (step S106).

Next, the abnormality determination unit 116 refers to the detection record information stored in the storage unit 150A, and determines whether or not the ammonia concentration detected at the predetermined time continues to increase for a predetermined number of days (step S108). ).

If the ammonia concentration detected at the predetermined time has not continued to rise for the predetermined number of days (step S108: NO), the abnormality determination unit 116 determines that the room 20 is in a normal state, and is outside the temperature range suitable for daily life until a predetermined time elapses (step S110).

If the detected room temperature is within the range of the life-suitable temperature (step S110: NO), the abnormality determination unit 116 determines that the temperature in the room 20 is normal, returns to step S100, and repeats the process. .

On the other hand, if the detected temperature in the room is outside the temperature range suitable for daily life until the predetermined time elapses (step S110: YES), the abnormality determination unit 116 determines that the temperature in the room 20 is abnormal. , and the communication unit 118 transmits to the management device 200 and the like that the temperature in the room 20 is abnormal (determination result) (step S112).

Further, in step S108, if the ammonia concentration detected at the predetermined time continues to increase for the predetermined number of days (step S108: YES), the abnormality determination unit 116 determines that the indoor 20 is in an abnormal state, and further It is determined whether or not the detected indoor temperature is outside the temperature range suitable for daily life until a predetermined time elapses (step S114).

If the detected temperature in the room is within the range of the life-suitable temperature until the predetermined time elapses (step S114: NO), the abnormality determination unit 116 determines that the temperature in the room 20 is normal, The communication unit 118 transmits to the management apparatus 200 or the like that the room 20 is in an abnormal state (determination result) (step S116).

On the other hand, if the detected temperature in the room is outside the temperature range suitable for daily life until the predetermined time elapses (step S114: YES), the abnormality determination unit 116 determines that the temperature in the room 20 is abnormal. Then, the communication unit 118 transmits that the room 20 is in an abnormal state and the temperature in the room 20 is an abnormal room temperature (determination result) (step S118).

In this way, the abnormality determination device 100A of the present embodiment detects an abnormal state indicating that the room 20 is contaminated based on the ammonia concentration detected by the ammonia sensor 102 installed in the room 20 where the resident lives. In order to determine whether or not it is, the room 20 in an abnormal state can be quickly confirmed while protecting the privacy of the resident, and the resident who is having difficulty leading a normal life can be found early. In addition, it is advantageous in suppressing the cost for repairing the room 20 and the like.

Further, when the ammonia concentration detected at a predetermined time continues to rise for a predetermined number of days, it is determined that the room 20 is in an abnormal state, so the state of the room 20 can be determined only by detecting the ammonia concentration. Therefore, it is possible to quickly confirm the abnormal state of the room 20 while protecting the privacy of the occupant with a simple configuration.

Furthermore, if the detected temperature of the room 20 is outside the range of the temperature suitable for living for a predetermined period of time, it is determined that the temperature of the room 20 is an abnormal room temperature that is not suitable for living. It is possible to determine the abnormal room temperature as well as the abnormal state of the room 20, which is advantageous for early detection by judging the condition of the resident who is having difficulty leading a normal life from multiple perspectives.

In addition, since the ammonia sensor 102 is installed on the ceiling of the room, it is possible to easily detect the concentration of ammonia using the property of ammonia which is lighter than air. Also, since the temperature sensor 104 is installed on the ceiling of the room 20 as well as the ammonia sensor 102, the detection conditions of the temperature sensor and the ammonia sensor 102 can be matched, and the abnormal state of the room 20 can be determined more accurately.

In addition, when it is determined that the room 20 is in an abnormal state, the fact is transmitted to the management device 200 or the like, so that the person who manages the resident, the family, etc., can quickly inform the resident living in the room 20 of the state. advantage over Further, when it is determined that the room temperature is abnormal, the fact that the room temperature is abnormal is transmitted to the management device 200 or the like, which is advantageous in confirming the state of the room 20 more accurately.

In addition, since the detected ammonia concentration and the detected room temperature are recorded in association with the date and time of detection, it is possible to more accurately identify when the room began to become abnormal and when the room temperature began to become abnormal. is advantageous.

In addition, in the abnormality determination system, since the determination result determined by the abnormality determination device 100A is transmitted to the management device 200 and the mobile terminal 300 (information processing device) connected via the network 30, A room 20 in an abnormal state can be quickly confirmed from a management device 200 or a portable terminal 300 located away from the room 20, and a resident who has difficulty leading a normal life can be found early.

In addition, since the dwelling 10 (building) is equipped with the abnormality determination device 100A, it is possible to quickly check the abnormal state of the room 20, and to quickly detect residents who are having difficulty leading a normal life. can be provided to

(Second embodiment)
In the first embodiment, whether or not the indoor 20 is in an abnormal state is determined based on whether or not the ammonia concentration detected at the predetermined time continues to increase for the predetermined number of days. Embodiment 2 is different in that it is determined whether or not the room 20 is in an abnormal state depending on whether or not the detected ammonia concentration exceeds the threshold concentration.

In the following description of the embodiment, the same reference numerals are given to the same parts and configurations as those of the first embodiment, and the description thereof will be omitted. I will focus on explaining.
Also, the overall configuration diagram of the abnormality determination system according to the present embodiment and the hardware configuration of the abnormality determination device 100B are the same as those in the first embodiment (see FIGS. 1 and 2).

Next, the functional configuration of the abnormality determination device 100B will be described. FIG. 6 is a functional configuration diagram of an abnormality determination device 100B according to the second embodiment. As shown in FIG. 6, abnormality determination device 100B of the present embodiment includes ammonia sensor 102, temperature sensor 104, and device main body 110. Device main body 110 includes storage unit 150B, signal reception unit 112, and storage unit 150B. , a recording control unit 114 , a determination information acquisition unit 120 , an abnormality determination unit 126 , and a communication unit 118 .

In addition to the detection record information of the first embodiment, the storage unit 150B stores determination information in which the threshold concentration of the ammonia concentration used when determining whether the room 20 is in an abnormal state is set. .

FIG. 7 is a diagram showing an example of determination information. As shown in FIG. 7, the storage unit 150B of the present embodiment stores the indoor temperature (° C.) and the threshold concentration (ppm) indicating the concentration of ammonia that serves as a criterion for determining whether the interior is in an abnormal state. Corresponding judgment information is saved.

Referring to the determination information shown in FIG. 7, for example, when the indoor temperature is 10° C. or higher and lower than 15° C., the threshold concentration of the ammonia concentration is X3 ppm, and when the indoor temperature is 20° C. or higher and lower than 25° C. , the threshold concentration of ammonia concentration is X5 ppm. Here, the threshold concentration of the ammonia concentration is set every 5°C, but it can be arbitrarily set every 2°C or every 3°C.

The reason why we set the criteria corresponding to the temperature is that ammonia (gas) tends to decrease in concentration when the temperature is low, and tends to increase in concentration when the temperature is high. This is for performing conversion and abnormality determination. For example, an ammonia concentration of 1 ppm at 5°C may correspond to 20 ppm at 35°C.

When determination information acquisition unit 120 and signal reception unit 112 receive detection signals from ammonia sensor 102 and temperature sensor 104, determination information is acquired from storage unit 150B.

The abnormality determination unit 126 determines whether or not the room 20 is in an abnormal state based on the concentration of ammonia detected by the ammonia sensor 102 . Further, based on the temperature detected by the temperature sensor 104, the abnormality determination unit 126 determines whether the temperature in the room 20 is an abnormal room temperature. Here, the determination as to whether or not the temperature in the room 20 is the abnormal room temperature is the same as in the first embodiment.

Specifically, the abnormality determination unit 126 refers to the determination information acquired from the storage unit 150B, and determines whether the detected ammonia concentration is equal to or higher than the threshold concentration corresponding to the detected temperature in the room 20. judge. When the detected ammonia concentration is less than the threshold concentration, the abnormality determination unit 126 determines that the room 20 is in a normal state indicating a state in which it is possible to live.

On the other hand, if the detected concentration of ammonia is equal to or higher than the threshold concentration, the abnormality determination unit 126 determines that the room 20 is in an abnormal state contaminated with excrement, putrefaction, or the like.

For example, referring to the determination information shown in FIG. 7, when the detected temperature in the room 20 is 18° C. and the ammonia concentration is 0.4 ppm, the detected ammonia concentration is a threshold corresponding to a temperature of 15° C. or more and less than 20° C. Since the concentration is less than X4 (for example, 0.8 ppm), it is determined that the room 20 is in a normal state. On the other hand, when the detected temperature in the room 20 is 18° C. and the ammonia concentration is 0.9 ppm, the detected ammonia concentration is equal to or higher than the threshold concentration X4 (for example, 0.8 ppm) corresponding to a temperature of 15° C. or more and less than 20° C. Therefore, it is determined that the room 20 is in an abnormal state.

Next, abnormality determination processing by the abnormality determination device 100B will be described. FIG. 8 is a flow chart showing the flow of abnormality determination processing by the abnormality determination device 100B of the first embodiment.

The processing from detection of ammonia concentration to recording of ammonia concentration and temperature (steps S200 to S206) is the same as in the first embodiment (steps S100 to S106).

Next, the determination information acquisition unit 120 acquires the determination information stored in the storage unit 150B (step S208). Then, the abnormality determination unit 126 refers to the acquired determination information and determines whether or not the detected ammonia concentration is equal to or higher than the threshold concentration corresponding to the detected temperature inside the room 20 (step S210).

If the detected ammonia concentration is less than the threshold concentration (step S210: NO), the abnormality determination unit 126 determines that the room 20 is in a normal state, and the detected temperature in the room has not passed the predetermined time. Until then, it is determined whether or not the temperature is outside the temperature range suitable for daily life (step S212).

If the detected room temperature is within the range of the life-suitable temperature (step S212: NO), the abnormality determination unit 126 determines that the temperature in the room 20 is normal, returns to step S200, and repeats the process. .

On the other hand, if the detected temperature in the room is outside the temperature range suitable for daily life until the predetermined time elapses (step S212: YES), the abnormality determination unit 126 determines that the temperature in the room 20 is abnormal. , and the communication unit 118 transmits to the management device 200 and the like that the temperature in the room 20 is abnormal (determination result) (step S214).

Further, in step S210, if the detected ammonia concentration is equal to or higher than the threshold concentration (step S210: YES), the abnormality determination unit 126 determines that the room 20 is in an abnormal state, and the detected indoor temperature is outside the temperature range suitable for daily life until a predetermined time elapses (step S216).

If the detected temperature in the room is within the range of the life-suitable temperature until the predetermined time elapses (step S216: NO), the abnormality determination unit 126 determines that the temperature in the room 20 is normal, The communication unit 118 transmits to the management device 200 or the like that the room 20 is in an abnormal state (determination result) (step S218).

On the other hand, if the detected temperature in the room is outside the temperature range suitable for daily life until the predetermined time elapses (step S216: YES), the abnormality determination unit 126 determines that the temperature in the room 20 is abnormal. Then, the communication unit 118 transmits that the room 20 is in an abnormal state and the temperature in the room 20 is an abnormal room temperature (determination result) (step S220).

Thus, the abnormality determination device 100B of the present embodiment has the following effects in addition to the effects of the first embodiment. That is, instead of determining whether the indoor 20 is in an abnormal state based on whether the ammonia concentration detected at a predetermined time continues to rise for a predetermined number of days as in the first embodiment, In the present embodiment, reference is made to determination information that associates the temperature of the room 20 with a threshold concentration that serves as a criterion for determining whether the room 20 is in an abnormal state, and the detected concentration of ammonia in the room 20 is When the concentration is equal to or higher than the threshold concentration corresponding to the temperature, it is determined that the room 20 is in an abnormal state. Therefore, it is possible to make a determination that takes into account the temperature dependence of the ammonia concentration. It is possible to quickly check the room 20 in an abnormal state while protecting it, and it is advantageous for early detection of residents who are having difficulty in living a normal life and for suppressing the cost of repairing the room 20. becomes.

Next, an example of determining an abnormal state in a room of a house using the abnormality determination device according to the first embodiment will be described.

<Case 1>
An ammonia sensor and a temperature sensor capable of detecting an ammonia concentration of 0.5 ppm or more were installed on the ceiling of the living room in a house for a 70-year-old living alone, and the state of the living room was determined. Then, the ammonia concentration detected by the ammonia sensor at 10 o'clock in the morning of the predetermined time increased from 0.5 ppm or less to 1.0 ppm and then to 1.2 ppm for seven consecutive days. In addition, although it was June, the indoor temperature detected by the temperature sensor was always above 30°C for a predetermined period of time. For this reason, when a family member who did not live together visited the room, food was scattered and began to rot in the room, and excrement, which appeared to be from incontinence, was on the floor. This elderly person had developed dementia, but because it was detected early, the adverse effects on the body were kept to a minimum.

<Case 2>
In a house where a mother and her 2-year-old child live together, an ammonia sensor and a temperature sensor capable of detecting an ammonia concentration of 0.5 ppm or more were similarly installed on the ceiling of the living room to determine the state of the living room. As a result, the mother and child were no longer seen from one month ago, and the ammonia concentration detected by the ammonia sensor at 10:00 a.m. at a predetermined time continued to rise from 0.5 ppm by about 0.2 ppm every day for two weeks. In addition, although it was March, the temperature inside the room detected by the temperature sensor fluctuated wildly between 3°C and 18°C, so we assumed that the air conditioning was not working. For this reason, when a counselor from the childcare consultation center visited, the room was littered with used baby diapers and dirty clothes. The child's height and weight appeared to be extremely lower or lighter than the norm for his age, and he wore out-of-season clothing such as shorts. This mother was in a state of neglect, but early detection allowed us to protect the infant and initiate treatment for the mother.

In the above example, the abnormality determination device of the present embodiment is used to determine the state of the room, so that the state of the room can be quickly confirmed while protecting the privacy of the occupants. We were able to detect early on the abnormal condition of the mother who was living with us, and we were able to deal with it.

In the embodiment described above, in the first embodiment, it is determined whether the ammonia concentration detected at a predetermined time has continued to rise for a predetermined number of days to determine whether the indoor 20 is in an abnormal state, In the second embodiment, it is determined whether or not the room 20 is in an abnormal state depending on whether or not the detected ammonia concentration is equal to or higher than the threshold concentration corresponding to the detected temperature of the room 20. However, both may be combined and implemented.

In the present embodiment, the storage units 150A and 150B for storing detection record information and determination information are provided in the abnormality determination devices 100A and 100B. Alternatively, the detection record information and determination information may be stored in a storage device or cloud storage, and data necessary for abnormality determination processing may be transmitted and received via the network 30 .

A program to be executed by the abnormality determination device of the present embodiment is pre-installed in a ROM or the like and provided. The program executed by the abnormality determination apparatus of the present embodiment is a computer-readable recording medium such as a CD-ROM, a CD-R, a DVD (Digital Versatile Disc), etc., in an installable or executable format. may be configured to be recorded and provided. Furthermore, the program executed by the abnormality determination device of the present embodiment may be stored in a computer connected to a network such as the Internet, and may be provided by being downloaded via the network.
