<< Processing or operation of location management system >>
Hereinafter, processing or operation of the location management system will be described with reference to FIGS. FIG. 8 is a sequence diagram showing processing of the location management system. FIG. 9A is a conceptual diagram showing a temperature distribution, and FIG. 9B is a conceptual diagram of heat source data indicating the presence or absence of a heat source. FIG. 10 is a conceptual diagram of heat source data indicating the presence or absence of all the heat sources in one room.

  Here, the position information management system 8 generates control data for controlling each control target device 2a, 2x based on various data detected by the control target device 2a22, and sends it to each control target device 2a, 2x. A process is disclosed in which the control target devices 2a and 2x perform control of light control, air volume, and the like by transmitting control data. For simplification of description, processing of the control target device 2a22 including the detection device 3 and the control target device 2a11 including the communication device 5 among the control target devices 2a will be described.

  First, as illustrated in FIG. 8, the detection unit 32 of the control target device 2a22 detects the temperature distribution of each region in the living room α (step S21). And the judgment part 33 judges whether temperature is in a predetermined range value (for example, 30 degreeC-35 degreeC) for every area | region, and the production | generation part 34 produces | generates heat source data based on the judgment result ( Step S22).

  Here, generation of heat source data will be described with reference to FIG. As a result of detecting the temperature of each region by the detection unit 32, when the temperature distribution of the nine regions is in the state shown in FIG. 9A, the generation unit 34 is a heat source as shown in FIG. 9B. Generate data. That is, the heat source data is indicated by heat source presence / absence information indicating the presence / absence of a heat source. A region where the temperature is 30 ° C. or higher is expressed as “1”, and a region where the temperature is lower than 30 ° C. is expressed as “0”.

  The detection unit 32 of the control target device 2a22 detects the illuminance, temperature, and humidity in the vicinity of the control target device 2a22 (step S23). And the transmission / reception part 31 transmits detection data with respect to the positional infomation management system 8 (step S24). This detection data includes the heat source data generated in step S22, and temperature / humidity data and illuminance data indicating the result detected in step S23. Thereby, the transmission / reception part 81 of the positional information management system 8 receives detection data. And the data of the state which the transmission / reception part 81 put together the heat-source data sent from each block is shown by FIG. FIG. 10 is a conceptual diagram of heat source data indicating the presence or absence of all the heat sources in one room. For example, the heat source data shown in FIG. 9B constitutes the first block at the upper left in FIG.

  Next, the storage / reading processing unit 59 of the position information management system 8 reads the layout information shown in FIG. 6A from the layout management DB 8001 (step S25). And the collation part 82 collates the layout information shown by FIG. 6 (A), and the heat source data shown by FIG. 10 (step S26). By this collation, for example, the position (a11) of the control target device in the layout information is “1”, that is, “there is a heat source” based on the heat source data.

  Next, the storage / reading processing unit 59 of the position information management system 8 searches the control guideline management DB 8002 using “1” and “0” indicating the presence / absence of the heat source in the heat source data as a search key, thereby corresponding control information. The luminous intensity is read (step S27). And the production | generation part 84 produces | generates the control data which show the light control degree with respect to the control object apparatus 2a11 (step S28). In the case of the control target device 2x as an air conditioner, the generation unit 84 generates control data indicating the air volume and the like for each control target device 2x.

  Next, the transmission / reception part 51 transmits each control data with respect to the control object apparatus 2a22, 2a11 (step S29-1, S29-2). On the other hand, the transmission / reception unit 31 in the detection device 3 of the control target device 2a22 receives control data. The transmission / reception unit 51 in the communication device 5 of the control target device 2a11 receives control data.

  Next, in the control target device 2a22, the control unit 35 of the detection device 3 generates a control signal to be output to the control target unit 20 as an LED lamp based on the control data (step S30-1). It outputs to the part 20 (step S31-1). Thereby, the light quantity of the control object part 20 as an LED lamp is controlled. Similarly, in the control target device 2a11, the control unit 55 of the communication device 5 generates a control signal to be output to the control target unit 20 as an LED lamp based on the control data (step S30-2). It outputs to the part 20 (step S31-2). Thereby, the light quantity of the control object part 20 as an LED lamp is controlled. For example, in FIG. 9A, since there is no heat source immediately below the control target device 2a22, it is indicated by “0”. Therefore, the control content of the control target device 2a22 has a dimming degree of 60% according to FIG. . On the other hand, in FIG. 9 (A), it is indicated by “1” that there is a heat source directly under the control target device 2a11. Therefore, the control content of the control target device 2a11 is 100% dimming according to FIG. . As a result, when the heat source is detected because there is a person, the light quantity of the LED is maximized, and when the heat source is not detected because there is no person, the light quantity of the LED is reduced, thereby realizing energy saving. Can do.

FIG. 12A is a conceptual diagram showing temperature distribution, and FIG. 12B is a conceptual diagram of heat source data indicating the presence or absence of a heat source.

  First, the generation unit 34 extracts a region where the determination unit 33 does not determine whether the temperature is within a predetermined range (for example, 30 ° C. to 35 ° C.) from the temperature distribution data (step S101). Then, the determination unit 33 determines whether the temperature of the region extracted in step S101 is within a predetermined range (step S102). For example, when an electric pot (water heater) is installed in a region where the control target device 2a13 having the device ID a13 is installed, as shown in FIG. May be 60 ° C. In such a case, even if a heat source is present, it is not within the range of a heat source by humans (for example, 30 ° C. to 35 ° C.), so that the heat source data indicates that there is no heat source as shown in FIG. “0” indicating “” is displayed.

  Next, when it is determined in step S102 that it is within the predetermined range (YES), the determination unit 33 determines that there is a heat source (step S103). On the other hand, if the determination unit 33 determines that it is not within the predetermined range (NO), it determines that there is no heat source (step S104). Then, after the processing in steps S103 and 104, the determination unit 33 determines whether or not the determination on whether or not the temperature is within the predetermined range is completed in all regions (step S105). If it is determined in step S105 that all areas have been determined (YES), the process in step S22 ends. On the other hand, if it is determined in step S105 that the determination of all areas has not been completed (NO), the process returns to step S101.

<Effect of the first embodiment>

Therefore, in the following, steps S203 and S204 are performed. The process will be described. However, in the second embodiment, the sensor driver 304 constituting the detection unit 32 stores detection data of each sensor for a certain time (for example, 10 minutes).

  First, in step S202, when it is determined that the temperature of the specific region is within the predetermined range (YES), the determination unit 33 stores the specific region that is stored in the detection unit 32 and is the determination target of step S202. The past temperature data in the same area is read out (step S203). Then, the determination unit 33 determines whether the temperature change rate of the specific region is equal to or higher than a predetermined value (for example, the temperature rises by 5 ° C. or more in 10 seconds) (step S204). For example, as shown in FIG. 14A, in the case of a side of a window, such as an area where the control target apparatus 2a12 with the apparatus ID a12 is installed, the temperature is higher in the daytime than in the surrounding area. Because it rises, it will be close to human temperature. For this reason, it is erroneously detected that there is a person even though there is no person. Therefore, by examining past temperatures, the determination unit 33 determines that the temperature is gradually increased by sunlight rather than a human when the temperature is gradually increased as shown in FIG. to decide. On the other hand, as shown in FIG. 15B, when the temperature suddenly rises as shown in FIG. 15B, the determination unit 33 can predict that the temperature has suddenly increased due to the human being appearing in the region, and is thus a heat source by humans. Judge.

  Next, in step S204, when the determination unit 33 determines that the temperature change rate is equal to or greater than a predetermined value, it determines that there is a heat source (step S205). On the other hand, if the determination unit 33 determines in step S204 that the temperature change rate is not equal to or greater than the predetermined value, it determines that there is no heat source (step S205). Thus, as shown in FIG. 14A, even if the specific region is 30 ° C., as shown in FIG. 14B, the heat source data indicates that there is no heat source. 0 ".

<Effects of Second Embodiment>
As described above, according to the present embodiment, even if the heat source has a temperature in the same predetermined range as that of a human, the region that gradually enters the predetermined range is an area close to the window and human. Since it can be assumed that there is no heat source, the presence of a heat source can be accurately detected by treating it as having no heat source. Thereby, there exists an effect that an energy saving can be implement | achieved more correctly.

<< Third Embodiment >>
<Features of Third Embodiment>
Hereinafter, the third embodiment will be described with reference to FIGS. 16 and 17. FIG. 16 is a flowchart illustrating a heat source data generation method according to the third embodiment. FIG. 17A is a conceptual diagram showing a temperature distribution, and FIG. 17B is a conceptual diagram of heat source data indicating the presence or absence of a heat source.

  In the third embodiment, steps S301, S302, S305, S306, and S307 correspond to steps S101, S102, S103, S104, and S105 of the first embodiment, respectively. Therefore, steps S303 and S304 are described below. The process will be described. However, in the third embodiment, the detection unit 32 is configured such that one block is configured by a 6 × 6 area instead of one block being configured by a 3 × 3 area as illustrated in FIG. 9. Has been. Moreover, one area | region of this embodiment is the range of a square of 35 cm x 35 cm, for example.

  First, when it is determined in step S302 that the temperature of the specific region is within the predetermined range (YES), the determination unit 33 extracts the temperature of the peripheral region of the specific region from the temperature distribution data (step S303). . Then, the determination unit 33 determines whether the temperature of the surrounding area is within the same predetermined range as the predetermined range in Step S302 (Step S304). For example, in the case where there is a cup containing coffee to be cooled in the room α, if it is 35 ° C., which is close to the human temperature, it will be erroneously detected that there is a human even though there is no human. In this case, the human is located not only in one area but also in a plurality of areas, but the cup is often located in one area. Therefore, by examining the surrounding area, if the temperature of the surrounding area is also within the predetermined range, the determining unit 33 determines that there is a heat source. If the temperature of the surrounding area is outside the predetermined range, the determining unit 33 determines that the heat source is Judge that there is no. In FIG. 17A, when the temperature of the specific region in the third row and second column is 33 ° C., the determination unit 33 determines that there is a heat source because the temperatures of the eight regions that are the peripheral regions are also within the predetermined range. To do. On the other hand, when the temperature of the specific region in the second row and the sixth column is 35 ° C., the determination unit 33 determines that there is no heat source because the temperatures of the five regions that are the peripheral regions are outside the predetermined range. As a result, as shown in FIG. 17B, the specific region in the third row and the second column indicates “1” indicating that there is a heat source, and the specific region in the second row and the sixth column indicates that there is no heat source. “0” is shown.

  Next, in step S304, when the determination unit 33 determines that the temperature of the peripheral region is within the predetermined range, it determines that there is a heat source (step S305). On the other hand, if the determination unit 33 determines in step S304 that the temperature of the surrounding area is outside the predetermined range, it determines that there is no heat source (step S305). Accordingly, as shown in FIG. 17A, even if the specific region in the second row and the sixth column is 35 ° C., as shown in FIG. “0” indicating that there is no data.

<Effect of the third embodiment>
As described above, according to the present embodiment, even if the heat source is a temperature in the same predetermined range as that of a human, if the range is narrow, it is not a human but a small object such as a coffee cup or a warmer and a human. Since it can be assumed that there is no heat source, the presence of a heat source can be accurately detected by treating it as having no heat source. Thereby, there exists an effect that an energy saving can be implement | achieved more correctly.
