  The network communication control unit 18 controls transmission / reception of control signals and information signals with the management server S via the communication network NW. The clock unit 19A has a function of outputting the current time (time information). In the present embodiment, a wired network using a cable or the like is assumed for the communication network NW. However, the present invention is not limited to this, and a wireless network may be used.

  The control unit 20 controls the operation of the entire fixed station reader R including the radio unit 16, the RSSI unit 17, the network communication control unit 18, the arrival time detection unit 19, and the clock unit 19A. That is, the control unit 20 performs signal processing according to a program stored in advance in the ROM while using the temporary storage function of the RAM. Specifically, the control unit 20 receives an input of an execution command for position detection processing from the management server S, performs detection processing of the mobile station tag T by wireless communication via the reader antenna 12, and displays the detection result as described above. The data is output to the management server S via the communication network NW. Similarly, the control unit 20 obtains temperature / humidity detection results from a sensor SR (described later) provided on the mobile station tag T from the management server S, or attribute information related to the person P stored in the mobile station tag T.

The air conditioning operation of each of the air conditioners AC1 to AC4 is controlled via the CC. The sensor SR-A provided in the air conditioner AC1 will be described later in a modified example of (3) below.

  For example, as shown in FIG. 3, the mobile station tag T is possessed or attached by the corresponding person P as described above by an appropriate method such as placing it in a pocket in the form of a card or hanging it from the neck. . The mobile station tag T includes an IC circuit unit 31 (storage unit), a tag antenna (first antenna unit) 32, and a sensor SR (first air conditioning detection unit) (the clock unit 35 will be described later). ).

  The IC circuit unit 31 includes a radio unit 33 that realizes radio functions such as modulation, demodulation, and amplification for transmitting and receiving radio signals, and a control unit 34 that controls the operation of the entire mobile station tag T including the radio unit 33. Have Note that the mobile station tag T used in this example is an active tag that is driven by a power supply (not shown in particular) provided therein. As a result, the mobile station tag T can receive a relatively weak radio signal.

  The sensor SR has a known configuration for detecting temperature, humidity, or wind speed as an air conditioning factor, and the detection result is input to the control unit 34 of the IC circuit unit 31. The detection results (temperature information, humidity information, etc.) input to the control unit 34 are read from the radio unit 33 via the tag antenna 32 in response to a transmission request (described later) from the base station based on the instruction from the management server S described above. Transmission to R is possible.

  As described above, the most significant feature of the present embodiment is that the person P can detect the position of the mobile station tag T and acquire the air conditioning preference information of the person P stored in the IC circuit unit 31 of the mobile station T. It is to realize the air conditioning state that is personally preferred. Hereinafter, the details will be sequentially described.

(A) Method Principle of Mobile Station Position Detection FIG. 4 is a diagram for explaining the principle of a method for detecting the position of the mobile station tag T in the air conditioning control system 1 of the present embodiment. 4 shows an example in which the position of one mobile station tag T is detected by three fixed station readers R1 to R3 in order to avoid the complexity of illustration.

  In FIG. 4, the mobile station tag T possessed by the person P can move to any coordinate position within the air conditioning control target area in which the plane coordinate system is set as described above, whereas the three fixed station readers R1 to R1 R3 is fixedly arranged at each known installation position within the same air conditioning control target area. The fixed station readers R1 to R3 are connected to one management server S through a communication network NW so as to be able to send and receive information.

  In this configuration, the management server S determines the distance from each fixed station reader R1 to R3 to the mobile station tag T based on the reception time difference of the radio signal from the mobile station tag T at each fixed station reader R1 to R3. Measure and detect. That is, at least one of the fixed station readers R1 to R3 transmits a predetermined transmission request signal to the mobile station tag T, and the mobile station tag T fixes each radio signal (distance detection radio signal) correspondingly. Transmit to the station leaders R1 to R3. At this time, the time (arrival time) from when the mobile station tag T transmits a radio signal for distance detection until it is received by the fixed station reader R is the spatial distance between the fixed station reader R and the mobile station tag T. Proportional to distance. When the distance from each fixed station reader R to the mobile station tag T is different, the arrival time becomes a different value for each fixed station reader R and a time difference occurs. The management server S can calculate the position of the mobile station tag T based on the time difference.

  That is, for example, the distance between the first fixed station reader R1 located at the coordinates (x1, y1) and the mobile station tag T located at the coordinates (x, y) is r1, and the second fixed position located at the coordinates (x2, y2). The distance between the station reader R2 and the mobile station tag T is r2, and the distance between the third fixed station reader R3 located at the coordinates (x3, y3) and the mobile station tag T is r3. In addition, the error s is based on the time lag of each of the clock units 19A of the fixed station readers R1 to R3. Then, each of the first fixed station reader R1, the second fixed station reader R2, and the third fixed station reader R3 receives the reception time when the distance detection radio signal transmitted from the mobile station tag T at time T0 is received as T1, Let T2 and T3.

Under the above conditions, in FIG.
r1 + s = √ {(x−x1) ² + (y−y1) ² } (1A)
r2 + s = √ {(x−x2) ² + (y−y2) ² } (1B)
r3 + s = √ {(x−x3) ² + (y−y3) ² } (1C)
Holds.

Then, by subtracting equation (1B) from equation (1A),
| R1-r2 | = c × | T1-T2 | (1D)
Moreover, by subtracting the formula (1C) from the formula (1A),
| R1-r3 | = c × | T1-T3 | (1E)
The relationship expressed by Note that c is a radio wave velocity (light speed = 2.997 × 10 ⁸ [m / s]).

  At this time, (the reception times T1, T2, and T3 are known as measured values), there are only three variables r1, r2, and r3. Therefore, the above two equations (1D) and (1E) are expressed by, for example, the Newton-Raphson method It is possible to specify the x and y coordinates (x, y) of the position of the mobile station tag T by solving the above.

  In the above example, each of the fixed station readers R1 to R3 only detects the reception time of the radio signal and transmits it to the management server S, and the positioning process (distance from the fixed station readers R1 to R3 to the mobile station tag T). Is calculated by the management server S, but is not limited thereto. That is, the control units 20 of the fixed station readers R1 to R3 transmit / receive the reception time information to each other, and the fixed station readers R1 to R3 perform calculation of the distance to the mobile station tag T (= position detecting means). And the calculation result (distance data) may be transmitted to the management server S. In the management server S, the three distance data from the respective fixed station readers R1 to R3 are totaled, and the position of the mobile station tag T is detected.

(B) Personal Air Conditioning Preferences Generally, air conditioners such as the air conditioners AC1 to AC4 have greatly different values of temperature, humidity, wind speed, etc. for individual individuals because the operating state affects the health of the human body. FIG. 5 is a diagram illustrating an example of the favorite temperature and the preferred humidity value of each of the persons P1, P2, and P3. As shown in the figure, in this example, the person P1 is a man in his 30s, the person P2 is a man in his 50s, and the person P3 is a woman in his 20s. In this case, the preference is different depending on the gender and age, but the preference may be different depending on the individual even in the same gender and the same generation.

  As an example of temperature, for example, it is assumed that the corresponding air conditioners AC1 to AC4 in any of the rooms Z1 to Z5 are controlled to operate at a temperature of 20 ° C. When the person P1 enters the room, since the temperature 20 ° C. matches the personal favorite temperature, the person P1 feels comfortable. However, when the person P3 enters the room, the temperature 20 ° C. is 5 ° C. lower than the personal favorite temperature (= 25 ° C.), so that the person P3 feels uncomfortable (cold). Thus, since there are individual differences in air conditioning preferences, it is impossible to achieve an optimal air conditioning environment when anyone enters the room when uniform air conditioning control is performed.

(C) Realization of environment corresponding to air conditioning preference (C-1) Use of air conditioning preference information and map information In this embodiment, each person P is referred to the map information based on the position detection results using readers R1 to R4. Is detected to have entered any of the rooms Z1 to Z4. On the other hand, personal air conditioning preference information of each person P is stored in the mobile station tag T, and the air conditioning preference information is read by the readers R1 to R4 of the rooms Z1 to Z4 in which each person P has entered the room. A certain air conditioner AC1 to AC4 is controlled to match the air conditioning preference.

As shown, the position coordinates where the fixed station reader R1 is arranged are (XR1, YR1), the position coordinates where the fixed station reader R2 is arranged are (XR2, YR2), and the fixed station reader R3 is The arranged position coordinates are (XR3, YR3), and the position coordinates where the fixed station reader R4 is arranged are (XR4, YR4). These pieces of information are used for calculating the position of the mobile station T and are used to determine the nearest fixed station reader R with respect to the mobile station tag T from which the position coordinates have been detected.

(C-2) Realization of environment corresponding to personal air-conditioning preferences (in the case of one-person room)
The air conditioning control when the person P1 enters the laboratory Z1 will be described with reference to FIG. In FIG. 11A, the management server S detects the position of the mobile station tag T1 at predetermined time intervals, and when the person P1 carrying the mobile station tag T1 opens the door and enters the laboratory Z1 from the corridor. Since the position coordinates of the mobile station tag T1 satisfy the range condition of the laboratory Z1 in the room database, the management server S detects that the position of the mobile station tag T1 is in the laboratory Z1. As a result, the management server S recognizes that the person P1 has entered the laboratory Z1.

  Thereafter, the management server S determines the nearest fixed station reader R using the position information of each fixed station reader R from the fixed station reader database. The air conditioning preference information (preferred temperature 20 ° C., humidity 50%; see FIGS. 5 and 6A) of the person P1 stored in the control unit 34 of the mobile station tag T1 is based on the request from the management server S. The data is transmitted in response to a request from the fixed station reader R1, and is acquired by the fixed station reader R1. The acquired air conditioning preference information of the person P1 is output to the management server S, and the management server S determines the air conditioner that covers the position from the acquired position information of the person P1 by the air conditioner database (in this case, It is determined that the air conditioner is AC1). The management server S outputs an instruction signal to the equipment control unit CC according to the air conditioning preference information, and controls the operation of the air conditioner AC1 determined to correspond to the position of the person P1. As a result, the air conditioner AC1 operates at a target temperature of 20 ° C. and a target humidity of 50% that matches the air conditioning preference information of the person P1. Further, at this time, the temperature and humidity near the person P1 are detected by the sensor SR provided in the mobile station tag T1, and the detection result is transmitted to the nearest fixed station reader R1 and further acquired by the management server S. . The management server S performs feedback control of the air conditioner AC1 by the equipment control unit CC so that the detection result by the sensor SR becomes the target temperature 20 ° C. and the target humidity 50%. As a result, an air conditioning environment (temperature 20 ° C., humidity 50%) comfortable for the person P1 is realized in the laboratory Z1.

  On the other hand, consider a case where the person P1 leaves the room from the state shown in FIG. 11A and then enters the person P2 as shown in FIG. When the person P1 leaves the laboratory Z1, the management server S detects that the position of the person P1 is outside the laboratory Z1, and outputs an instruction signal to the equipment control unit CC according to the detected position. The air conditioning control based on the personal preference of the person P1 in the operation of the air conditioner AC1 in the room Z1 is stopped, and the control is switched to a predetermined standard air conditioning control that is predetermined in advance regardless of the preference of each person P (the operation itself) In other words, when the user is in the room, control according to the air conditioning preference of the occupant, and when the user is not in the room, uniform normal control).

  In FIG. 11B, when the person P2 carrying the mobile station tag T2 opens the door and enters the laboratory Z1 from the corridor, the management server S positions the mobile station tag T2 in the laboratory Z1 as described above. Therefore, it is recognized that the person P2 has entered the laboratory Z1. Thereafter, as described above, the air conditioning preference information (preferred temperature 23 ° C., humidity 60%; see FIGS. 5 and 6B) of the person P2 stored in the control unit 34 of the mobile station tag T2 is the nearest fixed station reader. Sent to R1 for acquisition. As described above, the management server S controls the operation of the air conditioner AC1 via the equipment control unit CC, thereby performing feedback control so that the target temperature is 23 ° C. and the target humidity is 60%. As a result, an air conditioning environment (temperature 23 ° C., humidity 60%) comfortable for the person P2 is realized in the laboratory Z1.

(C-3) Realization of an environment corresponding to individual air-conditioning preferences (in the case of multiple rooms)
The above is an example of control when one person P is present in one room. On the other hand, when a plurality of persons P are present in one room, a predetermined priority order is determined, and control according to the air conditioning preference information of the person P1 having the highest priority order is performed.

  FIG. 12 is a diagram illustrating an example of how to determine the priorities. In this example, priority is given according to the gender and age group of the person P. First, the highest priority (relative priority is relatively high) is when the person P is a woman. This is based on the viewpoint that women should generally consider the air-conditioning environment from the viewpoints of physical strength, health, and beauty. In this case, the priority is always higher regardless of the age group of the woman (than other persons P who are men). Next, priority is given to the case of a person P of a senior generation (over 60s). The focus is on the health of the elderly. Next, the minor P is prioritized. It is also a consideration for health. Therefore, in this example, the priority of the person P other than that (male of age 20 to 59) is the lowest.

  Note that the priority order shown in FIG. 12 is relative, and if there is a female person P in the same room Z, the female air conditioning preference is given the highest priority. When an adult male has entered the room, priority is given to the air conditioning preference of the senior generation, which has a relatively high priority. In addition, if a plurality of persons P having the same priority are overlapped, select one of them by an appropriate method (providing a more detailed prioritization classification, giving priority to the person who entered the room first or the person who entered the room later) Simply determined by the tag ID). Alternatively, when the priority order shown in FIG. 12 is applied twice and one of a plurality of women is a senior generation and the rest are other generations, the preference of the air conditioning preference of senior generation women is given the highest priority. Or the like.

  Further, the classification of how to assign priorities is not limited to this example, and the priority is determined based on other attribute information of each person P, for example, the health condition (whether healthy or sick / injured). Also good. Or the attributes of the organization (company, etc.) that uses the building (President / Executive / Management / Temporary employee, Regular employee / Part / Part-time job, Affiliation of department / distant department near the building, or closely related to the room Z It may be determined depending on whether or not there is a person who has And (including the example of giving priority order shown in FIG. 12), the priority order may be given by appropriately combining them.

  An example of air conditioning control when a plurality of persons P enter the conference room Z2 will be described with reference to FIG. In FIG. 13 (a), two persons P, that is, a person P1 possessing the mobile station tag T1 and a person P2 possessing the mobile station tag T2 enter the conference room Z2. As described above, the management server S detects the positions of the mobile station tags T1 and T2 at predetermined time intervals, and the position coordinates of the mobile station tags T1 and T2 determine the range condition of the laboratory Z1 in the room database. By satisfying, it is detected that the positions of the mobile station tags T1 and T2 are in the laboratory Z1. As a result, the management server S recognizes that the persons P1 and P2 have entered the laboratory Z1.

  Here, since there are a plurality of persons entering the room, it is necessary to determine a priority order as to which person P should follow the air conditioning preference as described above. Therefore, the attribute information of the person P1 stored in the mobile station tag T1 (male, 30s; see FIGS. 5 and 6A) and the attribute information of the person P2 stored in the mobile station tag T2 (male, 60 (See FIG. 5 and FIG. 6B) are transmitted to the fixed station reader R2 in response to a request from the nearest fixed station reader R2 (determined by the management server S based on the fixed station database), To be acquired. The attribute information is output to the management server S. In this example, the management server S gives priority to the senior generation person P2 in accordance with the priority order setting shown in FIG. That is, the management server S instructs the nearest fixed station reader R2 to acquire air conditioning preference information from the wireless tag T2 (reference mobile station) related to the priority person P2. In response to this, the fixed station reader R2 transmits the stored air conditioning preference information of the person P2 (preferred temperature 23 ° C., humidity 60%; see FIGS. 5 and 6B) to the mobile station tag T2. Request. In response, the air conditioning preference information is transmitted from the mobile station tag T2 to the nearest fixed station reader R2 and acquired. The acquired air conditioning preference information of the person P2 is output to the management server S, and the management server S determines that the air conditioners that cover the position from the acquired position information of the person P2 are the air conditioners AC2a and Ac2b based on the air conditioner database. judge. Then, the management server S outputs an instruction signal to the equipment control unit CC according to the air conditioning preference information, and controls the operations of the air conditioners AC2a and AC2b in the conference room Z2 determined to correspond to the position of the person P2. As a result, the air conditioners AC2a and AC2b operate at a target temperature of 23 ° C. and a target humidity of 60% that match the air conditioning preference information of the person P2. Further, at this time, the temperature and humidity in the vicinity of the person P2 are detected by the sensor SR provided in the mobile station tag T2, and the detection result is transmitted to the nearest fixed station reader R2 and further acquired by the management server S. . The management server S performs feedback control of the air conditioners AC2a and AC2b by the equipment control unit CC so that the detection result by the sensor SR becomes the target temperature 23 ° C. and the target humidity 60%. As a result, an air conditioning environment (temperature 23 ° C., humidity 60%) comfortable for the person P2 is realized in the conference room Z2.

  Note that, as described above, the plurality of (two in this example) air conditioners AC2a and AC2b in the conference room Z2 are not limited to being operated in the same manner. That is, among the air conditioners AC2a and AC2b, it is sufficient to operate at least the air conditioner AC2a closest to the person P2 in accordance with the air conditioning preference information of the person P2 (this allows an optimum air conditioning environment for the person P2 quickly and quickly). The remaining air conditioner AC2b can be operated in another mode (different target temperature and target humidity). For example, the air conditioner AC2b may be a predetermined standard air conditioning control that is uniformly determined in advance regardless of the preference of each person P, or is controlled for an intermediate value between the air conditioning preference of the person P2 and the air conditioning preference of the person P1. (For example, the target temperature is 21.5 ° C. and the target humidity is 55%). Further, according to the occupancy position in the conference room Z1, for example, when the person T1 is near the air conditioner AC2b, the air conditioner AC2b may be controlled according to the air conditioning preference of the person P1. .

  FIG. 13B shows a case where a person P3 has further entered the conference room Z2 from the corridor from the state shown in FIG. 13A (that is, a total of three people are in the room). In FIG. 13B, when the person P3 carrying the mobile station tag T3 opens the door and enters the conference room Z2 from the corridor, the management server S, as described above, positions the mobile station tag T3 in the conference room Z2. It is detected that there is a new entry of the person P3 into the conference room Z2.

  Thereafter, attribute information (female, 20) of the person P3 stored in the control unit 34 of the mobile station tag T3 based on a transmission request from the nearest fixed station reader R2 based on an instruction from the server S for reviewing the priority order. (See FIG. 5 and FIG. 6C) is transmitted to the fixed station reader R2 and acquired. This attribute information is output to the management server S, and the management server S resets the person P3 who is a woman according to the priority order setting shown in FIG. Switch to P3). As a result, the management server S instructs the nearest fixed station reader R2 to acquire the air conditioning preference information from the wireless tag T3 (reference mobile station) related to the newly preferred person P3. In response, the fixed station reader R2 transmits the stored air conditioning preference information (preferred temperature 25 ° C., humidity 60%; see FIGS. 5 and 6C) of the person P3 to the mobile station tag T3. Request. In response, the air conditioning preference information stored in the control unit 34 of the mobile station tag T2 is transmitted to the nearest fixed station reader R2 and acquired. The acquired air conditioning preference information of the person P3 is output to the management server S, and the management server S outputs an instruction signal to the equipment control unit CC according to the air conditioning preference information, and the air conditioners AC2a and AC2b of the corresponding conference room Z2 Control the behavior.

  As a result, as described above, the air conditioners AC2a and AC2b operate at a target temperature of 25 ° C. and a target humidity of 60% that match the air conditioning preference information of the person P3. Further, at this time, the detection result of the temperature / humidity in the vicinity of the person P3 by the sensor SR provided in the mobile station tag T3 is acquired by the management server S via the nearest fixed station reader R2. The management server S performs feedback control of the air conditioners AC2a and AC2b as described above via the equipment control unit CC, and a comfortable air conditioning environment (temperature 25 ° C., humidity 60%) for the person P3 is realized.

(D) Control Sequence FIG. 14 shows the transmission and reception of various signals and control operations between the management server S, the fixed station readers R1 to R4, and the mobile station tags T1 to T3 in the position detection process prior to the air conditioning control. It is a sequence diagram showing an example. In FIG. 14, each procedure is basically represented by a time series change from the upper side to the lower side in the figure. As described above, signals are transmitted and received between the management server S and the fixed station readers R1 to R4 via the communication network NW. Further, signals are transmitted and received between the fixed station readers R1 to R4 and the mobile station tags T1 to T3 via wireless communication.

  First, in step SS10 shown in FIG. 14, the CPU 21 of the management server S moves to each of the fixed station readers R1 to R4 (or one specific fixed station reader R) via the network communication control unit 26. An instruction signal is output so as to transmit a radio wave transmission request for distance detection to the station tag T. Accordingly, in step SR10, the radio unit 16 of each fixed station reader R1 to R4 (or one specific fixed station reader R) transmits a radio wave transmission request signal to the mobile station tag T via the reader antenna 12.

  Then, the radio unit 33 of the mobile station tag T that has received the transmission request signal transmits a corresponding radio signal for distance detection via the tag antenna 32 in step ST10. The radio unit 16 of each of the fixed station readers R1 to R4 receives a radio signal for distance detection via the reader antenna 12 in step SR20. Then, the arrival time detection unit 19 detects the reception time information at that time, and the control unit 20 outputs the reception time information to the management server S via the network communication control unit 18.

  Then, in step SS20, the CPU 21 of the management server S calculates the distance to each mobile station tag T based on the difference in reception time (= difference in arrival time) input from each of the fixed station readers R1 to R4. . Thereafter, in the next step SS30, the CPU 21 of the management server S calculates the position coordinates of the mobile station tag T by the method described above with reference to FIG. 4 based on the distance calculated in step SS20 (= position detecting means). ).

  In addition, transmission of the transmission request from the management server S to the fixed station reader R in step ST10 is always performed at a predetermined time interval as described above. As a result, the position detection of the mobile station tags T1, T2, T3 is always performed in real time. Further, the present invention is not limited to the transmission of the distance detection radio signal from the mobile station tag T in response to the transmission request from such fixed station readers R1 to R4 (or a specific fixed station reader R). That is, the mobile station tag T continues to transmit a radio signal spontaneously at regular time intervals, and each fixed station reader R receives the radio signal continuously transmitted, and based on this, the management server S performs distance detection. May be. Also in this case, the position detection of the mobile station tags T1, T2, T3 is always performed in real time.

  Next, in step SS40, the CPU 21 of the management server S uses the position coordinates of the mobile station tag T calculated in step SS30 and the room database previously stored in the large-capacity storage device 25 to determine the person P. The rooms Z1 to Z4 located at that time are determined.

  Thereafter, the process proceeds to step SS50, and based on the discrimination results in step SS40 (summing the discrimination results of all mobile station tags T), a plurality of persons P (in other words, a plurality of mobile station tags T) enter the room. Determine if there is room Z. If there is no room in which a plurality of people have entered (any of the rooms Z1 to Z4 is for only one person P or no one has entered), the determination in step SS50 is not satisfied, and the routine goes to step SS70.

  In step SS70, for each room Z in which one person P (in other words, one mobile station tag T) has entered, each mobile station tag T is assigned to the target mobile station (standard) for air conditioning control for that room Z. Mobile station) (= reference mobile station setting means). Thereafter, this flow is terminated.

  On the other hand, in step SS55, if there is a room Z in which a plurality of persons enter the room, the determination is satisfied, and the routine goes to step SS60.

  In step SS60, the CPU 21 of the management server S determines the nearest fixed station reader R in the room Z in which the plurality of persons enter the room using the position information of each fixed station reader R from the above-mentioned fixed station reader database. . Thereafter, the CPU 21 of the management server S sends, via the network communication control unit 26, the nearest fixed station reader R corresponding to the room Z in which the plurality of persons enter the corresponding plurality of mobile station tags T ( An instruction signal is output to transmit an attribute information transmission request (for the corresponding person P). As a result, in step SR30, the wireless unit 16 of the corresponding nearest fixed station reader R transmits the attribute information transmission request signal to the plurality of mobile station tags T via the reader antenna 12.

  Then, the radio units 33 of the plurality of mobile station tags T that respectively receive the transmission request signals transmit the corresponding attribute information (person P) via the tag antenna 32 in step ST20. The corresponding wireless unit 16 of the nearest fixed station reader R receives the attribute information via the reader antenna 12 in step SR40. And the control part 20 outputs the attribute information to the management server S via the network communication control part 18, and the management server S acquires the attribute information. In addition, it is not restricted to storing attribute information in each mobile station tag T in this way. That is, the identification information (tag ID) of each mobile station tag T and the corresponding attribute information of the person P may be stored in a separate database in association with each other. In this case, the tag ID is transmitted instead of the attribute information in step ST20, the tag ID is output to the management server S in step SR40, and the management server S searches the database (attribute information database) using the tag ID as a key. It is sufficient to acquire the attribute information to be used. Furthermore, the attribute information or the tag ID is not transmitted in response to a request from the nearest fixed station reader R based on the request from the management server S as described above, but the above steps SS10, SR10, ST10 are performed. The distance detection radio signal may be transmitted at all times in real time (see a modification of (2) described later).

  Thereafter, in step SS100, the CPU 21 of the management server S performs air-conditioning control from a plurality of mobile station tags T based on a predetermined priority for each attribute according to the attribute information input from the fixed station reader R. A target mobile station determination process for determining a target mobile station (reference mobile station) is performed (reference mobile station determination means; see FIG. 15 described later for details). When step SS100 is completed, this flow ends.

  FIG. 15 is a flowchart showing a detailed procedure of the target mobile station determination process in step SS100 of FIG. 14 executed by the CPU 21 of the management server S. This control procedure corresponds to the priority classification shown in FIG.

  In FIG. 15, first, in step SS105, it is determined whether or not the attribute information from the plurality of mobile station tags T input in step SR40 includes information indicating that the person P is a woman. If there is a female person P in the corresponding room Z, the determination in step SS105 is satisfied, and in step SS110, one mobile station tag T corresponding to the person P is set as the target mobile station in the air conditioning control. This routine is then terminated. If there is no female person P in the corresponding room Z, the determination in step SS105 is not satisfied, and the routine goes to step SS115.

  In step SS115, it is determined whether or not the attribute information from the plurality of mobile station tags T input in step SR40 includes information indicating that the person P is a senior generation (60 generations or more). If there is a senior generation person P in the corresponding room Z, the determination in step SS115 is satisfied, and in step SS120, one mobile station tag T corresponding to the person P is set as the target mobile station in the air conditioning control. Set and exit this routine. When the senior generation person P does not exist in the corresponding room Z, the determination in step SS115 is not satisfied, and the process proceeds to step SS125.

  In step SS125, it is determined whether or not the attribute information from the plurality of mobile station tags T input in step SR40 includes information indicating that the person P is a minor. If there is a minor person P in the corresponding room Z, the determination in step SS125 is satisfied, and in step SS130, one mobile station tag T corresponding to the person P is assigned to the target mobile station in the air conditioning control. And exit this routine. If there is no minor P in the corresponding room Z, the determination at step SS125 is not satisfied, and the routine goes to step SS140.

  In step SS140, the mobile station tag T related to the remaining person P is determined in the air-conditioning control (all of the determinations in step SS105, step SS115, and step SS125 are not satisfied and the man is 20 to 59 years old). The target mobile station is set, this routine is terminated, the process returns to the sequence of FIG. 14, and the procedure shown in FIG. 14 is terminated.

  If a plurality of persons P having the same classification category (see FIG. 12) enter the same room Z, as described above, the female senior generation → the female minor> Select more appropriate priorities such as other generations of women, prioritize the person who entered the room first (or the person who entered the room later), or simply determine by tag ID. What should I do? Or you may make it use the intermediate value (average value etc.) of the value of each air-conditioning preference information (a detailed flow procedure is abbreviate | omitted).

  FIG. 16 is transmitted and received among the management server S, the fixed station readers R1 to R4, the mobile station tags T1 to T3, and the equipment control unit CC in the air conditioning control process executed based on the position detection result by the position detection process. It is a sequence diagram showing an example of transmission and reception of various signals and control operation. FIG. 16 shows each procedure in a time-series change similar to FIG. 14 described above. Between the management server S and the equipment control unit CC (in this example), signals are transmitted and received by wired communication not via wireless communication. ing.

  In FIG. 16, first, in step SS210, the CPU 21 of the management server S passes through the network communication control unit 26 to the nearest fixed station readers R1 to R4 related to the target mobile station tag determined in step SS70 or step SS100. An instruction signal is output so as to transmit an air conditioning preference information request (for the corresponding person P) to the mobile station tag T. As a result, in step SR50, the radio unit 16 of the corresponding nearest fixed station reader R transmits an air conditioning preference information request signal to the mobile station tag T via the reader antenna 12.

  And the radio | wireless part 33 of the mobile station tag T which received the said transmission request signal transmits the air conditioning preference information of the corresponding person P via the tag antenna 32 by step ST30. The corresponding radio units 16 of the fixed station readers R1 to R4 receive the air conditioning preference information via the reader antenna 12 in step SR60. And the control part 20 outputs the received air-conditioning preference information to the management server S via the network communication control part 18, and the management server S acquires air-conditioning preference information (information acquisition means). In addition, it is not restricted to memorize | storing air-conditioning preference information in each mobile station tag T in this way. That is, the identification information (tag ID) of each mobile station tag T and the corresponding air conditioning preference information of the person P may be stored in a separate database in association with each other. In this case, the tag ID is transmitted instead of the air conditioning preference information in step ST30, the tag ID is output to the management server S in step SR60, and the management server S searches the database (air conditioning preference information database) using the tag ID as a key. It is sufficient to acquire the corresponding air conditioning preference information (information acquisition means). Further, the air conditioning preference information or the tag ID is not transmitted in response to a request from the nearest fixed station reader R based on the request from the management server S as described above, but the above step SS10, step SR10, step At the time of transmitting the distance detection radio signal in ST10, it may be always transmitted in real time (refer to a modification of (1) described later).

  Then, in step SS220, the CPU 21 of the management server S determines the air conditioner that covers the position from the position information of the person P who has acquired the air conditioning preference information by the air conditioner database (covers the range to which any of the air conditioners AC1 to AC4 corresponds). Based on the air conditioning preference information, a control instruction signal corresponding to the equipment control unit CC is output (= control means). The equipment control unit CC that has input this controls the air conditioner AC determined to correspond to the position of the person P in step SC10, and performs an operation that matches the input air conditioning preference information. In addition, when a plurality of persons P enter a room Z, only the mobile station tag T, which is the target mobile station, transmits only air-conditioning preference information as described above and is acquired by the management server S. Not limited. That is, air conditioning preference information is transmitted from all mobile station tags T existing in one room Z and acquired by the management server S. When the target mobile station is determined as described above, the target movement is performed. The air conditioning control of the corresponding air conditioner AC may be performed using the air conditioning preference information regarding the station.

  On the other hand, in step SS230, the CPU 21 of the management server S sends the mobile station tag T (with the corresponding sensor SR) to the nearest fixed station readers R1 to R4 related to the target mobile station tag via the network communication control unit 26. ) Output an instruction signal to transmit a detection signal request. Thereby, in step SR70, the radio unit 16 of the corresponding nearest fixed station reader R transmits the detection signal request signal to the mobile station tag T via the reader antenna 12.

  Then, the radio unit 33 of the mobile station tag T that has received the transmission request signal transmits a detection signal (detection result of temperature, humidity, etc.) of the corresponding sensor SR via the tag antenna 32 in step ST40. The corresponding radio units 16 of the fixed station readers R1 to R4 receive the sensor detection result information via the reader antenna 12 in step SR80. Then, the control unit 20 outputs the received sensor detection result to the management server S via the network communication control unit 18.

  The CPU 21 of the management server S that has received the sensor detection result in step SR80, in the next step SS240, the temperature and humidity values included in the air conditioning preference information received in step SR60, and the temperature based on the sensor detection result.・ Determine whether the humidity and other values match. If the air conditioning preference information matches the sensor detection result, the determination in step SS240 is satisfied, it is considered that a comfortable environment desired by the person P has been formed, and this flow is ended. If the air-conditioning preference information and the sensor detection result do not match, the determination in step SS240 is not satisfied, and the process returns to step SS220 and the same procedure is repeated.

  In step ST20 and step ST30, attribute information and air conditioning preference information are transmitted from the mobile station tag T in response to a transmission request from the nearest fixed station reader R. However, the present invention is not limited to this. That is, the mobile station tag T voluntarily transmits attribute information and air conditioning preference information at regular time intervals, and the nearest fixed station reader R receives the radio signal continuously transmitted, and the management server S responds based on the radio signal. You may make it perform the process to perform.

  In the present embodiment configured as described above, when a radio signal for distance detection is transmitted from the mobile station tags T1 to T3, the radio signal is received by the radio unit 16 of the fixed station readers R1 to R4. The arrival time detector 19 detects the reception time of the radio signal at this time. As a result, the management server S detects the position of each of the mobile station tags T1 to T3 based on the reception time difference information of the fixed station readers R1 to R4 (step SS30), and further determines which room using the room database from the position detection result. Whether the user is in Z is detected in real time (step SS40). In addition, the management server S responds to requests from the fixed station readers R1 to R4, which are determined to be nearest from the positions of the mobile station tags T1 to T3 by the fixed station reader database, and corresponds to the mobile station tags T1 to T3. The air conditioning preference information (preferred temperature / humidity, etc.) of the persons P1 to P3 is transmitted from the mobile station tags T1 to T3, received by the nearest fixed station readers R1 to R4, and then acquired by the management server S. (Step SR60).

  And management server S is based on the air-conditioning preference information of the persons P1-P3 corresponding to the acquired mobile station tags T1-T3, and uses the air-conditioner database to locate the detected mobile station tags T1-T3. The air conditioners AC1 to AC4 that are determined to be compatible (in other words, the room Z in which the persons P1 to P3 enter) are controlled. This realizes the air conditioning operation (operation aimed at the preferred temperature, preferred humidity, etc.) that the people P1 to P3 prefer the air conditioners AC1 to AC4 in the room Z in which the people P1 to P3 enter. To do. Therefore, it is possible to realize an air conditioning environment that is personally optimal for the persons P1 to P3.

  In this embodiment, in particular, the temperature, humidity, and the like in the vicinity of the persons P1 to P3 are detected by the sensor SR provided in the mobile station tags T1 to T3, and feedback control is performed by the management server S based on the detection result. Thereby, it is possible to reliably realize an air conditioning environment that is personally optimal for the persons P1 to P3.

  In the present embodiment, in particular, when a plurality of mobile station tags T exist in the same room Z, one mobile station tag T as a reference for air conditioning control is determined, and the person P corresponding to the mobile station tag T is determined. The air conditioners AC1 to AC4 are controlled along the air conditioning preference information. In this way, by determining the mobile station tag T as a reference for air conditioning control, it is possible to perform optimum control corresponding to the tag as a target for air conditioning control. In particular, priority is given to each mobile station tag T, and air conditioning control is performed in accordance with the higher priority order, thereby clearly determining which mobile station tag T is the target of air conditioning control. Can be made smoother and faster.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described.

(1) When acquiring air conditioning preference information from identification information acquired at the time of reception of a distance detection radio signal In other words, in the above embodiment, first, position detection is performed by transmitting a distance detection radio signal from the mobile station tag T, Thereafter, the mobile station tag T separately transmits the air conditioning preference information to the nearest fixed station reader R corresponding to the position detection result. On the other hand, in this modification, identification information (tag ID) corresponding to each mobile station tag T is acquired together with the transmission of the distance detection radio signal, and this is used (a person stored in advance in the database). P air conditioning preference information).

  FIG. 17 is a sequence diagram illustrating an example of transmission and reception of various signals and control operations performed between the management server S, the fixed station readers R1 to R4, and the mobile station tags T1 to T3 in the present modification. It is a figure corresponding to FIG.14 and FIG.16. In this example, for convenience of explanation, a case where only one mobile station tag T exists in the same room Z will be described as an example. The same steps as those in FIGS. 14 and 16 are denoted by the same reference numerals, and description thereof will be omitted or simplified as appropriate.

  17, step SS10 and step SR10 are the same as in FIG. 14, and the CPU 21 of the management server S outputs an instruction signal to each fixed station reader R1 to R4 (or one specific fixed station reader R), and step SR10. Thus, each of the fixed station readers R1 to R4 (or one specific fixed station reader R) transmits a radio wave transmission request signal toward the mobile station tag T.

  Thereafter, in step ST10 similar to FIG. 14, the mobile station tag T that has received the transmission request signal transmits a corresponding radio signal for distance detection. The radio signal at this time includes identification information (tag ID) of each mobile station tag T. Then, in step SR20 similar to FIG. 14, each of the fixed station readers R1 to R4 receives a distance detection radio signal including the tag ID. Then, the reception time information detected by the arrival time detection unit 19 as described above and the tag ID corresponding thereto are output to the management server S.

  Thereafter, Step SS20, Step SS30, and Step SS40 are the same as those in FIG. That is, in step SS20, the distance between each fixed station reader R and each mobile station tag T is calculated based on the difference in reception time, and in the next step SS30, the position of each mobile station tag T is detected. In SS40, the room Z in which each person P is located is determined using the room database.

  Thereafter, the process proceeds to step SS45 newly provided, and predetermined air conditioning (previously stored in association with the tag ID of each mobile station tag T and the attribute information of the corresponding person P) using the tag ID acquired in step SR20 as a key. The preference information database (not shown) is accessed, and the air conditioning preference information of the corresponding person P is acquired.

  When step SS45 ends, the process proceeds to step SS220 similar to FIG. That is, the CPU 21 of the management server S determines the air conditioner covering the position from the position information (acquired in step SS30) of the person P who has acquired the air conditioning preference information by the air conditioner database (which of the air conditioners AC1 to AC4 corresponds). It is determined whether the range is covered), and a control instruction signal corresponding to the equipment control unit CC is output based on the air conditioning preference information (= control means).

  After that, step SS230 and subsequent steps are the same as those in FIG.

  In the above description, the case where only one mobile station tag T exists in the same room Z has been described as an example. However, the present invention is not limited to this, and a plurality of mobile station tags T exist in the same room Z. It can also be applied to cases. In this case, prior to accessing the air conditioning preference information database in step SS45, the attribute information database is accessed in the same manner as described above to acquire the attribute information of each mobile station tag T from the tag ID, and FIG. The target mobile station may be determined by the target mobile station determination process described above, and the air conditioning preference information database may be accessed using the tag ID of the determined target mobile station as a key.

  The present modification configured as described above also achieves the same effect as that of the above embodiment. In addition, since it is sufficient to store only the tag ID without storing the air conditioning preference information in the mobile station tag T, the memory consumption of the IC circuit unit 31 of the mobile station tag T can be reduced. Further, even if the air conditioning preference of each person P changes, there is an advantage that it can be dealt with by changing only the stored content on the air conditioning preference information database side while keeping the stored content on the mobile station tag T side as it is.

(2) When performing air conditioning control based on the movement prediction of the mobile station In other words, not only the air conditioners AC1 to AC4 are controlled according to the current room entry status of the person P (mobile station tag T), but also the final of the moving person P This is a case where the moving part is predicted and the air conditioners AC1 to AC4 at the part are controlled first (in a state where the person P has not arrived).

  The content of this modification is demonstrated using FIG.18 and FIG.19. In this example, the person P1 possessing the mobile station tag T1 is usually in the living room Z3 and is performing desk work, and it is known in advance that the person will make a round trip to the toilet Z4 several times a day. FIG. 18 shows a state where the person P1 has entered the toilet Z4. In this state, as described above, based on the communication between the fixed station reader R1 determined to be the closest based on the position detection result and the mobile station tag T1, the air conditioner AC4 of the toilet Z4 includes the air conditioning preference information of the person P1. Operation is performed at a matched target temperature of 20 ° C. and target humidity of 50%.

  Here, consider a case where the person P1 opens the door of the toilet Z4 from the state shown in FIG. 18 (FIG. 19). At this time, the behavior pattern of the normal person P1 is previously stored in the management server S as a history. For example, the person P1 makes a round trip from the room Z3 to the toilet Z4 to the room Z3 several times a day. Is also stored in the management server S as a history. Therefore, if the person P1 is detected to leave the toilet Z4, the air conditioning control of the living room Z3 is performed prior to the movement of the person P1.

  Specifically, it is detected that the mobile station tag T1 has gradually moved from the toilet bowl or the hand-washing area to the door side by referring to the room database based on the above-described position detection result for the mobile station tag T1 (refer to the movement locus H). Further, when it is detected that the person P1 has entered the hallway as shown in FIG. 19, the CPU 21 of the management server S automatically predicts that the final movement position (scheduled movement position) of the person P1 is the room Z3. (= Movement prediction means; see movement prediction locus Ho). Then, before the entrance of the person P1 into the living room Z3 is detected by referring to the room database based on the position detection result for the mobile station tag T1, the fixed station reader R1 that has been closest to the toilet Z4 is moved. Based on the air conditioning preference information of the person P1 acquired based on the communication with the station tag T1, the air conditioner AC3 in the room Z3 operates at a target temperature of 20 ° C. and a target humidity of 50% under the control of the equipment control unit CC according to the instruction of the management server S. Start. At this time, the air conditioner AC4 of the toilet Z4 switches the control to a predetermined standard air conditioning control that is uniformly determined in advance regardless of the preference of each person P (the operation itself continues).

  In this modification, before the person P1 reaches the moving room Z3, which is the moving position, the corresponding air conditioner AC3 can realize an air conditioning environment that is personally optimal for the person P1, in advance. Will improve.

(3) When correcting sensor This modification will be described with reference to FIGS. 20 (a) and 20 (b). In this example, air conditioning control in the laboratory Z1 is shown as an example. In FIG. 20A, in this example, a sensor SR-A as a second air conditioner detection unit is provided in advance for the air conditioner AC1 provided in the laboratory Z1. This sensor SR-A has a known configuration for detecting temperature, humidity, wind speed, or the like as an air conditioning factor, similar to the sensor SR provided in the mobile station tag T. The sensor SR may have the same configuration or a different configuration. The sensor SR-A is fixedly provided in the air conditioner AC1, and is, for example, more reliable (not likely to cause an error) than the sensor SR on the mobile station tag T side.

  As shown in FIG. 20A, in the state where the person P1 is in the laboratory Z1 alone, the air conditioner AC1 has the target temperature of 20 ° C. as described above based on the air conditioning preference information of the person P1. Operation with feedback control is performed. At this time, the detected temperature that is the source of the feedback control is switched from the sensor SR of the mobile station tag T1 to the sensor SR-A provided in the air conditioner AC1 by an appropriate operation of the person P1. As a result, the air conditioner AC1 performs an operation under feedback control such that the temperature of 20 ° C. is detected by the sensor SR-A.

  Here, it is assumed that the person P1 reaches sufficiently close to the air conditioner AC1 for the purpose of sensor check (correcting if there is an error) of the mobile station tag T1. As described above, since the air conditioner AC1 operates based on the detection result of the highly reliable sensor SR-A so that the target temperature is 20 ° C., the ambient temperature of the sensor SR of the mobile station tag T1 sufficiently close to the air conditioner AC1. Can be considered to be 20 ° C.

  Therefore, in this state, as shown in FIG. 20 (b), the management server S causes communication between the nearest fixed station reader R1 and the mobile station tag T1 based on the above-described position detection result, so that the mobile station tag The output signal of the sensor SR is corrected (calibrated) so that the detection result of the sensor SR of T1 becomes 20 ° C. (in the example shown, correction of 1 ° C. from 21 ° C. to 20 ° C. is performed). For this correction, a correction coefficient for correcting the output signal may be set in an appropriate means provided in the sensor SR, or the output signal from the sensor SR is corrected in the fixed station reader R1 as described above. Correction coefficients may be set, or correction may be performed by setting similar correction coefficients in the management server S1. In any case, the portion where the signal is corrected using the correction coefficient functions as the correcting means described in each claim.

  In this modified example, by correcting the sensor SR on the mobile station tag T1 side based on the sensor SR-A provided in the air conditioner AC1, more accurate air conditioning factors (temperature, humidity, wind speed, etc.) are detected. Can do.

(4) When performing positioning by the TOA method In the above, a so-called TDOA (Time Differenceence) in which distance measurement processing is performed based on a reception time difference of each fixed station reader R with respect to a radio wave signal for distance detection from the mobile station tag T. of Arrival) has been described as an example, but is not limited thereto. That is, distance measurement processing may be performed using a TOA (Time of Arrival) method. In this case, the aforementioned clock 35 is provided for the mobile station tags T1 to T3, and the clocks of the mobile station tags T1 to T3 and the fixed station readers R1 to R4 are adjusted. Then, the arrival time (propagation time) from the mobile station tags T1 to T3 to the fixed station readers R1 to R4 is calculated from the transmission time at the mobile station tags T1 to T3 and the reception times at the fixed station readers R1 to R4. Based on this, position detection processing can be performed by each of the mobile station tags T1 to T3.

  Also by this modification, the same effect as the above-mentioned embodiment and each modification is acquired.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.
