The device control system 100 further includes a plurality of communication terminals 7, a controller 200, and a plurality of sensors (a plurality of temperature sensors 9).

The device control system 100 determines the environment (for example, temperature) of each area 5 in a building having the plurality of areas 5 by controlling the operation of each of the plurality of air conditioners (air conditioners) 8 as a plurality of devices. The environment (predetermined temperature) can be adjusted. The building is, for example, an office building having a plurality of areas 5 for each floor. Each area 5 is, for example, the entire space of an appropriate room such as a laboratory such as a chemistry laboratory and a physics laboratory, an office for offices, a library, a fitness room, a laundry room, or at least a part of the space. Is. Hereinafter, a case where the area 5 is set for each room of the building will be described.

The plurality of air conditioners 8 are arranged so as to have a one-to-one correspondence with the plurality of areas 5. Each air conditioner 8 can adjust the temperature of the corresponding region 5 to a predetermined temperature (for example, 26 degrees) or to a temperature within a predetermined range (for example, 24 to 27 degrees).

The predetermined state is, for example, a state in which the temperature of the region 5 becomes a predetermined temperature.

The plurality of sensors are composed of a plurality of temperature sensors 9 as an example. The plurality of temperature sensors 9 are arranged so as to have a one-to-one correspondence with the plurality of regions 5. Each temperature sensor 9 detects the temperature around the temperature sensor 9. Each temperature sensor 9 transmits the detection result to the receiver 2 corresponding to the region 5 in which the temperature sensor 9 is arranged.

The first temperature sensor 91 among the plurality of temperature sensors 9 is arranged in the first region 51, and detects the temperature in the first region 51. The second temperature sensor 92 out of the plurality of temperature sensors 9 is arranged in the second region 52, and detects the temperature in the second region 52.

The controller 200 can monitor the operating state of each air conditioner 8. The controller 200 controls each air conditioner 8 according to the control information D3 output by the control information output system 1. The controller 200 controls the operating state of each air conditioner 8 by generating, for example, a control signal for each air conditioner 8 based on the control information D3 and outputting the control signal to each air conditioner 8. The controller 200 adjusts the environmental state of the area 5 in which each air conditioner 8 is arranged according to the detection result of the temperature sensor 9 arranged in the same area 5 as each air conditioner 8 and the operating state of each air conditioner 8. ..

The receiving system 13 is configured to perform wireless communication with each of the plurality of communication terminals 7. The receiving system 13 has a plurality of receivers 2 as an example. The plurality of receivers 2 are arranged in each of the plurality of areas 5. Each receiver 2 receives the second information D2 from each communication terminal 7.

The second information D2 is information defined for each user 6. The second information D2 is information including, for example, terminal information of the communication terminal 7 carried by the user 6 and information regarding an environment comfortable for the user 6. The information regarding the environment comfortable for the user 6 is, for example, the information regarding the temperature, and the information regarding the temperature at which the user 6 feels comfortable. The terminal information of the communication terminal 7 is information assigned to each communication terminal 7. Therefore, the second information D2 is different information for each user 6.

The control information output system 1 is information on the position of a target area in which a user 6 (person) carrying a communication terminal 7 capable of communicating with a plurality of receivers 2 exists among the plurality of areas 5 (hereinafter, first information). It has a function of generating (called D1). The target area is an area in which a user 6 who carries a communication terminal 7 capable of communicating with a plurality of receivers 2 exists among the plurality of areas 5.

The control information output system 1 acquires the second information D2 from each communication terminal 7 via each receiver 2. The control information output system 1 has a function of generating control information D3 for controlling the air conditioner 8 arranged in the target area according to the first information D1 and the second information D2. The control information output system 1 has a function of outputting the control information D3 to the controller 200.

(2) Configuration of Communication Terminals The plurality of communication terminals 7 are, for example, mobile terminals that periodically output radio signals using radio waves as a medium. Each communication terminal 7 is a so-called beacon terminal. The communication method of the wireless signal is, for example, Bluetooth (registered trademark). The wireless signal communication method may also be, for example, Wi-Fi (registered trademark), specified small wireless power communication, or the like. Each communication terminal 7 (71, 72, 73) is carried by a plurality of users 6 (61, 62, 63) who use the building. As an example, the user 6 carries a specific communication terminal 7 assigned to each user 6 among a plurality of communication terminals 7. More specifically, the first user 61 carries the first communication terminal 71. The second user 62 carries the second communication terminal 72. The third user 63 carries the third communication terminal 73. That is, each communication terminal 7 and its user 6 have a one-to-one correspondence. Each of the plurality of users 6 is movable with respect to each of the plurality of areas 5 (plurality of rooms). Therefore, each of the plurality of communication terminals 7 moves with respect to each of the plurality of areas 5 in accordance with the movement of the user 6.

The plurality of communication terminals 7 periodically transmit the second information D2 to the server 10 by a wireless signal. The second information D2 is held in, for example, the non-volatile memory of the communication terminal 7.

(3) Configuration of Receiving System The receiving system 13 has a plurality of receivers 2 as an example. Each receiver 2 receives a radio signal transmitted by the communication terminal 7. Further, each receiver 2 receives the second information D2 transmitted by the radio signal. Each receiver 2 generates information regarding the reception strength of the radio signal based on the received radio signal. Each receiver 2 is configured to transmit information to the information generation unit 3 of the server 10, which will be described later, by wireless communication using radio waves as a medium. More specifically, after receiving the radio signal from the communication terminal 7, each receiver 2 transmits the second information D2, the receiver information, and the information regarding the reception strength of the radio signal to the server 10. Each receiver 2 holds the receiver information assigned to each receiver 2 in a non-volatile memory or the like possessed by the receiver 2. The receiver information is, for example, a number (001,002 ...) Consisting of a three-digit number, but is not limited to this example. Each receiver 2 may transmit information to the server 10 not only by wireless communication but also by wired communication such as Ethernet (registered trademark) and power line carrier communication.

By the way, the plurality of receivers 2 are arranged in a plurality of predetermined areas 5, respectively. That is, the plurality of receivers 2 are arranged so as to have a one-to-one correspondence with the plurality of regions 5. Each region 5 is, for example, a region within a circle having a predetermined radius centered on each receiver 2. The predetermined radius means, for example, a distance at which the reception intensity of the radio signal received by the receiver 2 becomes equal to or higher than a predetermined threshold value.

The plurality of receivers 2 may transmit information regarding the reception strength of the radio signal from one of the plurality of communication terminals 7 to the server 10. For example, in FIG. 2, among the plurality of receivers 2, the first receiver 21 and the second receiver 22 are arranged so as to correspond to the adjacent first region 51 and the second region 52, respectively. There is. Here, both the first receiver 21 and the second receiver 22 may receive a radio signal from the first communication terminal 71. In FIG. 2, the reception strength of the radio signal received by the first receiver 21 is larger than the reception strength of the radio signal received by the second receiver 22. Therefore, the server 10 can determine that the first communication terminal 71 exists in the first area 51 in which the first receiver 21 is arranged.

Hereinafter, the information including the information regarding the reception strength of the radio signal received by at least one of the plurality of receivers 2 and the receiver information transmitted by the radio signal is referred to as "notification information". .. The notification information is information for the information generation unit 3 of the server 10, which will be described later, to specify an area in which at least one communication terminal 7 exists in the plurality of areas 5. Therefore, the plurality of receivers 2 output the notification information for notifying the area in which the communication terminal 7 exists among the plurality of areas 5 to the information generation unit 3.

(4) Configuration of Control Information Output System The control information output system 1 includes an information generation unit 3 and a processing unit 4, as shown in FIGS. 1 and 2. The control information output system 1 further includes a storage unit 12 and a communication unit 11. The control information output system 1 has a server 10 as an example.

The server 10 includes, for example, a storage unit 12, a communication unit 11, and a processor.

The communication unit 11 receives notification information from each of the plurality of receivers 2. The communication unit 11 has a function of receiving detection results from each of the plurality of temperature sensors 9 and transmitting the detection results to the controller 200.

As an example, the server 10 realizes the information generation unit 3 and the processing unit 4 by the processor reading and executing the program stored in the storage unit 12. The server 10 is not limited to reading the program from the storage unit 12, and may download the program from the outside of the server 10 or read the program from the storage device outside the server 10.

The storage unit 12 includes, for example, a rewritable non-volatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage unit 12 holds a first table in which the area 5 in which each receiver 2 is arranged and the position information of each area 5 with respect to the building are associated with each other. The storage unit 12 holds a first table, category information, area parameters, and category parameters.

The first table is information showing the correspondence between the plurality of receivers 2 and the plurality of regions 5. The first table is, for example, an information table in which the area 5 in which each receiver 2 is arranged is associated with the position information of each area 5 with respect to the building. Each receiver 2 is arranged so as to have a one-to-one correspondence with each area 5. The information generation unit 3 can specify the position of the region in which the communication terminal 7 exists among the plurality of regions 5 by referring to the first table using the receiver information transmitted by the plurality of receivers 2. ..

The category information is information about a category for each of a plurality of regions 5 categorized according to the characteristics of each region. In other words, the category information is information for dividing a plurality of regions 5 into groups having common characteristics of the regions. The categories of the category information are categorized according to the difference in the environmental conditions required in each area 5, such as a laboratory, an office, a break room, and a hot water supply room.

The area parameter and the category parameter are parameters related to the area 5 in which the communication terminal 7 exists.

The area parameter is information for designating the operating state of each of the plurality of devices arranged in each area 5. When the plurality of devices are the air conditioners 8, the area parameter is information for designating the operating state of each of the air conditioners 8 arranged in each area 5. The area parameters include information that specifies that the temperature of the area 5 is set to a predetermined temperature, information that specifies that the temperature of the area 5 is set to a predetermined temperature range, and the like.

The category parameter is information for designating the operating state of each air conditioner 8 arranged in the area 5 classified into each category. The category parameter is used to adjust the environment of a plurality of regions 5 belonging to the same category to the same state.

The information generation unit 3 receives the second information D2 and the notification information (receiver information and information regarding reception strength) from at least one receiver 2. Based on the notification information, the information generation unit 3 can specify which area 5 of the plurality of areas 5 is the area 5 in which at least one communication terminal 7 exists. For example, when the information generation unit 3 receives the second information D2 and the notification information from one receiver 2, the information generation unit 3 refers to the first table using the receiver information of the notification information, so that one communication terminal 7 The region 5 in which the is present can be specified. Further, when the second information D2 and the notification information are received from the plurality of receivers 2, the information generation unit 3 compares the reception strength included in the plurality of notification information. The information generation unit 3 can specify the area 5 in which the specific communication terminal 7 exists by referring to the first table using the receiver information of the notification information having the highest reception strength for the specific communication terminal 7. can. The information generation unit 3 generates the first information D1 regarding the area 5 in which the specific communication terminal 7 exists.

That is, the information generation unit 3 has the first information D1 based on the signals received by the plurality of receivers 2 from the communication terminal 7 and the first table (correspondence between the plurality of receivers 2 and the plurality of regions 5). To generate.

The information generation unit 3 outputs the first information D1 and the second information D2 to the processing unit 4.

Here, FIGS. 1 and 2 show a case where the communication terminal 7 is one, and the other communication terminals 7 are omitted. However, even if there are a plurality of communication terminals 7, the information generation unit 3 may be used. , The area 5 in which each communication terminal 7 exists can be individually specified in the plurality of areas 5. Since each communication terminal 7 can be specified by the terminal information different for each communication terminal 7, the information generation unit 3 individually specifies the area 5 in which each communication terminal 7 exists, as in the above description.

According to the above configuration, the information generation unit 3 can specify the area 5 in which the communication terminal 7 exists by referring to the first table using the notification information. Therefore, the information generation unit 3 can specify the area 5 in which the communication terminal 7 exists without acquiring the position information from the communication terminal 7. That is, the information generation unit 3 can specify the position of the target area in which the user 6 who carries the communication terminal 7 exists among the plurality of areas 5.

Further, the information generation unit 3 counts the number of communication terminals 7 in the area 5 in which the communication terminal 7 exists, and outputs information regarding the number of the communication terminals 7 to the processing unit 4. That is, the information generation unit 3 outputs information regarding the number of users 6 existing in the target area to the processing unit 4.

The processing unit 4 generates control information D3 for controlling each air conditioner 8 arranged in the area 5 in which the communication terminal 7 exists, based on the first information D1 and the second information D2.

The processing unit 4 outputs the control information D3 to the controller 200.

The processing unit 4 determines a parameter for setting the target area into a predetermined environment according to the number of communication terminals 7 in the target area and the user 6 existing in the target area. Hereinafter, the parameter for setting the target area in which the communication terminal 7 exists in a predetermined environment is referred to as "control information D3". The processing unit 4 determines the control information D3 according to, for example, the first information D1, the second information D2, the first table, the area parameter, and the category parameter.

As shown in Table 1, the category parameter is the temperature information set for each category. The categories are categorized into laboratories, offices, etc. as an example. The category parameters are set to, for example, 24-26 degrees in the laboratory category and 25-28 degrees in the office category. The category parameters may be categorized for each area 5 existing on the same floor (floor), or may be categorized for each building.

As shown in Table 2, the area parameter is the temperature information set for each area 5, and different temperature information can be set for each area. The area parameters of a chemistry laboratory included in the laboratory category are, for example, 23-25 degrees. Further, the area parameter can be omitted, and as an example, the area parameter is not set in the conference room included in the office category.

Hereinafter, at least one of the area parameter and the category parameter is referred to as "area characteristic". The characteristics of the regions may not necessarily be set in each of the plurality of regions 5.

Also, the plurality of categories do not necessarily have to have category parameters. The plurality of categories may have, for example, control information for controlling the operating state of each of the plurality of air conditioners 8 without specifying the temperature. As an example, the information regarding the plurality of categories may be information for the controller 200 to prohibit the setting change of the air conditioner 8 in a predetermined time zone.

When the first information D1 contains information about one communication terminal 7, the processing unit 4 determines the control information D3 based on the second information D2. When the first information D1 contains information indicating that a plurality of communication terminals 7 exist in one area 5, the processing unit 4 determines the control information D3 based on the plurality of second information D2.

The processing unit 4 outputs the control information D3 to the controller 200. The controller 200 adjusts the environment of the area 5 to a predetermined environment by controlling the operating state of each air conditioner 8 arranged in the area 5 where at least one communication terminal 7 exists based on the control information D3.

(5) Operation of the processing unit for determining the control information The operation for the processing unit 4 to determine the control information D3 will be described. In the following description, the second information D2 includes temperature information as a parameter relating to the environment of the region 5 in which the communication terminal 7 exists. The temperature information is information indicating that the temperature of the region 5 in which the communication terminal 7 exists indicates the temperature of the environment in which the user 6 carrying the communication terminal 7 feels comfortable. The temperature information is predetermined for each user 6 who carries the communication terminal 7.

The processing unit 4 determines the control information D3 according to the number of communication terminals 7 in the area 5 (target area) indicated by the first information D1, the second information D2, and the first information D1, and the characteristics of the target area.

First, when the number of communication terminals 7 existing in the target area is one, the operation of the processing unit 4 to determine the control information D3 will be described with reference to FIG.

The processing unit 4 acquires the first information D1, the second information D2, and information regarding the number of communication terminals 7 from the information generation unit 3 (S1). The processing unit 4 determines whether the number of communication terminals 7 is one or a plurality (S2). When the number of communication terminals 7 is one (S2: one), the processing unit 4 determines whether or not the characteristics of the area 5 are set in the target area by any of the area parameter and the category parameter. .. The characteristics of the target area differ depending on whether or not the area parameter and the category parameter are held in the storage unit 12 with respect to the target area. The processing unit 4 determines whether or not any of the area parameter and the category parameter is set in the area 5 in which the communication terminal 7 exists by referring to the area parameter and the category parameter using the information about the target area. (S4).

When the characteristic of the area is not set in the area 5 where the communication terminal 7 exists (S4: no setting) and the number of the communication terminals 7 is one (S6: 1), the processing unit 4 Determines the temperature information of the second information D2 as the control information D3 (S8).

A case where the characteristic of the area is set in the area 5 in which the communication terminal 7 exists (S4: with the setting) will be described. The processing unit 4 determines whether the temperature of the second information D2 is within or outside the temperature range of the characteristic (S5). When the average value of the temperature of the second information D2 is within the temperature range of the characteristic (S5: Yes), the number of communication terminals 7 is one (S6: 1), so that the processing unit 4 is the first. 2 The temperature information of the information D2 is determined as the control information D3 (S8). When the temperature of the second information D2 is outside the temperature range of the characteristic (S5: No), the processing unit 4 controls the value closest to the temperature of the second information D2 in the temperature range of the characteristic. (S7).

Here, when both the area parameter and the category parameter include the parameter related to the area 5, the processing unit 4 determines the information of the area parameter as the control information D3 as an example. Further, when neither the area parameter nor the category parameter includes the parameter related to the area 5, the processing unit 4 determines whether the number of communication terminals 7 existing in the target area is one or a plurality.

Next, when there are a plurality of communication terminals 7 existing in the target area, the operation of the processing unit 4 to determine the control information D3 will be described with reference to FIG.

When the number of communication terminals 7 is plural (S2: plural), the processing unit 4 obtains the average value of the temperatures of the plurality of second information D2 acquired from the information generation unit 3 by calculation (S3). ), The calculation result is stored in the storage unit 12. The processing unit 4 determines whether or not the characteristic of the area 5 is set in the target area by any of the area parameter and the category parameter (S4). When the characteristic is not set in the target area (S4: no setting), the processing unit 4 determines whether the number of communication terminals 7 existing in the target area is one or a plurality (S6). Since the number of communication terminals 7 is plural (S6: plural), the processing unit 4 determines the average value of the temperatures of the second information D2 as the control information D3 (S9).

When the characteristic is set in the target region (S4: with setting), the processing unit 4 determines whether the average value of the temperature of the second information D2 is within or outside the temperature range of the characteristic (S5). When the average value of the temperature of the second information D2 is within the temperature range of the characteristic (S5: Yes), the number of communication terminals 7 is plural (S6: plural), so that the processing unit 4 uses the second information. The average value of the temperature of D2 is determined as the control information D3 (S9).

When the average value of the temperature of the second information D2 is outside the temperature range of the characteristic (S5: No), the processing unit 4 has the highest average value of the temperature of the second information D2 in the temperature range of the characteristic. A close value is determined as the control information D3 (S7).

By the way, in the above description, the processing unit 4 determines whether or not the characteristics of the region are set in S4, but this determination is not an essential configuration. The processing unit 4 may be configured by omitting the processing of S4 and S5, for example. In that case, for example, the processing unit 4 determines the temperature information of the second information D2 as the control information D3 when the number of the communication terminals 7 is one, and the second information when the number of the communication terminals 7 is a plurality. The average value of the temperature of the information D2 may be determined as the control information D3.

The attribute of the user 6 is information including the gender and the health state of the user 6 of the communication terminal 7.

The second table holds information for each user 6 (terminal information, temperature information, gender information, and health condition information). The second table is an information table that associates terminal information corresponding to each user 6, temperature information, gender information, and health condition information. For example, the processing unit 4 refers to the second table using the terminal information of one of the plurality of terminal information, and thus relates to the temperature information corresponding to the user 6 who carries one communication terminal 7 and the gender. Information and information about health status can be specified.

The second table further holds weight information. The weight information is information used when the processing unit 4 determines the control information D3, and the control information D3 (here, a parameter relating to temperature) determined by the processing unit 4 differs depending on the weighting coefficient. The weight information is a value determined according to the gender of the user 6, a value determined according to the health condition of the user 6, and a value determined according to the number of communication terminals 7 existing in the target area. And, including.

The weighting coefficient when the gender of the user 6 is male is, for example, "0.8", and the weighting coefficient when the gender of the user 6 is male is, for example, "1.0". The health condition of the user 6 is divided into, for example, A level when the health condition is good, B level when there is no problem in the health condition, and C level when the health condition is neither A level nor B level. .. The weight coefficients of A level, B level, and C level are "1.0", "1.1", and "1.2", respectively. The weighting coefficient determined according to the number of users 6 existing in the target area is, for example, "1.4" when the number of the users 6 is 1 or more and less than 5, and the number of the users 6. Is "1.0" when there are 5 or more and less than 10 people, and "0.8" when the number of the users 6 is 10 or more. The number of users 6 existing in the target area is equal to the number of communication terminals 7.

Here, an example of the parameters held by the second table will be described with reference to Tables 3 to 6.

The parameters in Table 3 are parameters relating to the first user 61 carrying the communication terminal 7 whose terminal information is 001. The first user 61 is a male, prefers an environment of 24 degrees, and has an A level of health. The parameters in Table 4 are parameters relating to the second user 62 carrying the communication terminal 7 whose terminal information is 002. The second user 62 is a female, prefers an environment of 27 degrees, and has a health condition of B level. The parameters in Table 5 are parameters relating to the third user 63 carrying the communication terminal 7 whose terminal information is 003. The third user 63 is a male, prefers an environment of 29 degrees, and has a health condition of C level. The parameters in Table 6 are weighting coefficients determined according to the number of users 6 existing in the target area.

Here, an example of an operation in which the processing unit 4 determines the control information D3 using the parameters of the second table will be described. As an example, the processing unit 4 determines the control information D3 by the equation 1.

(Control information D3) = ((Σ ((temperature information for each user 6) × (weight coefficient for gender for each user 6) × (weight coefficient for health condition for each user 6)) / (user 6) )) + ((Weight related to the number of users 6) × (Temperature of region 5))) / 2 ... (Equation 1)
Equation 1 indicates that the control information D3 is determined so that the value is closer to the temperature information of the female user 6 than to the male user. Equation 1 indicates that the control information D3 is determined so that the health state of the user 6 becomes a value closer to the temperature information of the user 6 in the order of C level, B level, and A level. Equation 1 indicates that the control information D3 is determined so that the temperature gradually decreases according to the number of users 6.

By the way, when the characteristic of the region 5 in which the communication terminal 7 exists is set in the storage unit 12, the processing unit 4 has the temperature obtained based on the equation 1 and the characteristic of the region 5 described in the first embodiment (region). The control information D3 may be determined based on the parameter or category parameter). For example, when the temperature obtained based on the equation 1 is out of the temperature range determined by the characteristics of the region 5, the processing unit 4 controls the temperature to be the closest to the temperature range determined by the characteristics of the region 5. Information D3 may be defined. Regarding the operation when the control unit determines the control information D3 based on the temperature obtained by the control unit using the equation 1 and the characteristics of the region 5, "second information D2" in the description of the operation of the control unit in the first embodiment. "Temperature of" may be read as "Temperature obtained by the control unit using Equation 1."

As described above, in the control information output system 1 of the second embodiment, the second information D2 preferably includes information regarding the attributes of the person (user 6). The attribute of the person (user 6) referred to here is information including the gender and health state of the user 6 of the communication terminal 7. Thereby, the control information output system 1 can adjust the environment of the area 5 for each person (user 6) based on the attribute of the person (user 6). By the way, the attribute of the person (user 6) may be information including at least one of the gender and the health state of the user 6 of the communication terminal 7.

In the control information output system 1 of the second embodiment, it is preferable that the second information D2 includes information on the health state of a person (user 6). The information regarding the health condition of the person (user 6) referred to here is information indicating the result of the pre-diagnosed health examination. Thereby, the control information output system 1 can adjust the environment of the region 5 for each person (user 6) based on the information regarding the health condition of the person (user 6). By the way, the information on the health condition of the person (user 6) may also include, for example, information on the mood of the person (user 6) that changes according to the physical condition of the user 6. In that case, the communication terminal 7 may be configured so that the information regarding the health condition can be changed according to the operation of the user 6, for example.

In the control information output system 1 of the second embodiment, the processing unit 4 is a control determined based on the number of people (users 6) existing in the target area, the first information D1 and the second information D2. It is preferable that the information D3 is output. As a result, the processing unit 4 can output different control information D3 having different contents depending on whether the number of people existing in the target area is one or a plurality of people.

By the way, the second table may further hold information regarding the authority for each user 6. The information regarding the authority is information for designating the priority order of the parameters related to the attributes of each user 6 when a plurality of users 6 exist in one area 5. For example, when the information about the authority for each of the plurality of users 6 existing in one area 5 is held in the second table, the processing unit 4 has the attribute parameter of the user 6 having the highest priority authority. May be generated as the control information D3. Further, the processing unit 4 may change the weight information based on the information regarding the authority.

Information on permissions may be automatically set in the second table by, for example, the processor of the server 10 executing a predetermined program, or manually set in the second table by an operator using a mobile terminal. You may. The mobile terminal is, for example, a smartphone, a tablet terminal, a portable personal computer, or the like. In addition, the information regarding the authority may be held in the communication terminal 7, for example. In that case, the processing unit 4 may be configured to acquire information regarding the authority via the communication unit 11 of the control information D3 generation system.

The weight information is not limited to meaning the weight information regarding the gender of the user 6 and the weight information regarding the health condition of the user 6, for example, regarding the age of the user 6 and the mood that changes according to the physical condition. It may be weight information. Further, the weight information is at least one of weight information regarding the gender of the user 6, weight information regarding the health condition of the user 6, age of the user 6, and weight information regarding the mood that changes according to the physical condition. It suffices to include weight information.

The above-mentioned equation 1 for the processing unit 4 to obtain the control information D3 is an example, and other appropriate equations may be used for the determination.

When the device control system 100 includes a sensor capable of detecting the movement (acceleration) of a person and an object instead of the plurality of temperature sensors 9, the control information D3 is generated according to the presence or absence of the movement of the person and the object. It may be configured in. For example, when the user 6 carrying the communication terminal 7 in the target area continues to move at an acceleration equal to or higher than a predetermined threshold value, the device control system 100 sets the temperature higher than when the user 6 does not move. It may be configured to generate the control information D3 lowered by several degrees (for example, once). Since the body temperature of the user 6 who keeps moving may have risen due to sweating or the like, it is better to lower the temperature than when the user 6 is not moving to make the environment more comfortable for the user 6. Can be done.

The processing unit 4 may change the content of the control information D3 to be generated depending on whether or not the timing for generating the control information D3 is within a predetermined period. For example, the processing unit 4 generates control information D3 based on the first information D1 and the second information D2 during a predetermined period (for example, during a period from 9:00 to 18:00), but outside the period, the control information D3 is generated. It may be configured not to generate D3. In addition, for example, the processing unit 4 generates the control information D3 according to the authority of the user 6 during the period, but outside the period, the control information D3 is generated without using the information regarding the authority of the user 6. It may be configured to generate.

By the way, the association between the user ID in the second table and the information about the user 6 corresponding to the user ID (information about the terminal information, temperature information, gender, health condition, and each weight) can be changed. For example, the communication terminal 7 carried by a specific user 6 can be changed to be carried by another user 6. In this case, the communication terminal 7 and the user 6 are appropriately associated with each other by changing the association between the user ID in the second table and the information about the user 6 corresponding to the user ID.

For example, in a facility such as a hospital, when a user 6 (patient) who was using a specific communication terminal 7 is discharged from the hospital, the specific communication terminal 7 may be carried by another user 6 (patient). .. In that case, the area 5 in which the communication terminal 7 exists and the user 6 of the communication terminal 7 are changed, but the association between the user ID in the second table and the information about the user 6 corresponding to the user ID is changed. As a result, the communication terminal 7 and the user 6 are appropriately associated with each other.
