The wind direction control unit 5 includes a member that controls the direction of the wind to be blown in order to control the temperature and humidity of the room, that is, the wind direction in the horizontal direction and the vertical direction, and can control the wind direction independently in the horizontal direction and the vertical direction. . The wind direction control unit 5 changes the wind direction according to the control of the control unit 7 when the resident 10 sets the wind direction with the remote controller.

  The environment detection unit 6 detects the environmental state of the living room and acquires information on the environmental state of the living room. In addition, the environment detection unit 6 detects the position of the resident 10 and acquires the position information of the resident 10. The information on the environmental state of the room includes information on the temperature and humidity of the room. The environment detection unit 6 receives, for example, the amount of infrared rays radiated from an object by a plurality of light receiving units joined with different kinds of metals, calculates an electromotive force due to a temperature difference between different kinds of metals due to the Seebeck effect, and measures the living room A thermopile method is used to measure the surface temperature of the region. Thereby, the environment detection part 6 detects the temperature of a living room, detects the presence or absence of the resident 10 in a living room, and when the resident 10 exists in a living room, the attribute of whether the resident 10 is an adult or a child It is possible to detect the temperature distribution of the resident 10 and the like. The environment detection unit 6 includes a filter that transmits light in the infrared transmission region outside the light receiving unit and blocks visible light, thereby reducing the influence on the measurement temperature due to sunlight, moisture in the bathroom, and the like.

  The control unit 7 is set by the resident 10, the biological information of the resident 10 acquired by the biological information detection unit 3, the environmental state information of the living room detected by the environment detection unit 6, and the location information of the resident 10. The air conditioning control content for the air conditioning unit 4 and the wind direction control unit 5 is determined using information such as the set temperature from the remote controller. Specifically, the control unit 7 sets priorities for a plurality of residents 10 existing in the room using the biometric information of each resident 10 acquired by the biometric information detection unit 3. The control unit 7 sets the air conditioning control content for each resident 10 using the environmental state and the biometric information of the resident 10. And the control part 7 determines the air-conditioning control content with respect to the air-conditioning part 4 and the wind direction control part 5 using the priority for every resident 10, and the air-conditioning control content. As described above, the air conditioning control content includes the wind direction information for the wind direction control unit 5. The control unit 7 controls the operations of the air conditioning unit 4 and the wind direction control unit 5 with the determined air conditioning control content. The control unit 7 may further determine the air conditioning control contents of the air conditioning unit 4 and the wind direction control unit 5 using information on the room temperature detected by a room temperature detection unit (not shown) that detects the room temperature that is the temperature of the living room. .

  The control unit 7 may have a function of identifying the resident 10 when the resident information is obtained from the biological information detection unit 3. For example, when unique identification information is assigned to each biological information detection unit 3, the control unit 7 uses the identification information of the biological information detection unit 3 transmitted from the biological information detection unit 3 together with the resident information. The person 10 can be identified. By identifying the resident 10, the control unit 7 can grasp the time at which the resident 10 enters and leaves the room, a change in biological information, a change in the position in the room, and the like.

  The control part 7 is comprised by the microcomputer etc., for example. The microcomputer includes a storage unit including a ROM (Read Only Memory), a RAM (Random Access Memory), a nonvolatile memory, and the like, and a CPU (Central Processing Unit) that reads a program stored in the storage unit and executes arithmetic processing. And an input / output port for inputting / outputting a signal to / from the outside of the signal processing unit. For example, in the case of dedicated hardware, the control unit 7 includes a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), Alternatively, a combination of these may be used. In addition, the structure of the control part 7 is not limited to these.

  It continues and the operation | movement which the air conditioner 2 of the environment control system 1 implements the air-conditioning control of a living room is demonstrated. FIG. 3 is a flowchart showing the operation of the air conditioner 2 according to Embodiment 1. First, in the environmental control system 1, when the resident 10 starts the operation of the air conditioner 2 using a remote controller or the like, the control unit 7 of the air conditioner 2 acquires resident information from the biological information detection unit 3. Thus, it is recognized that a specific resident 10 is present in the room (step S1). The control unit 7 records the acquired resident information. The control part 7 may hold | maintain resident information inside, and may hold | maintain it at the memory | storage part which is not illustrated in FIG. The biometric information detection unit 3 may transmit resident information to the control unit 7 when there is an acquisition request from the control unit 7, or may periodically transmit resident information to the control unit 7.

  The environment detection unit 6 of the air conditioner 2 detects the environmental state of the living room, specifically, the temperature and humidity in the living room. Moreover, the environment detection part 6 detects the position of the occupant 10 who exists in a living room with an environmental state. The environment detection unit 6 outputs the detected environmental state information and the resident 10 position information to the control unit 7. The control unit 7 acquires the environmental state information and the resident 10 position information from the environment detection unit 6 (step S2). The control unit 7 records the acquired environmental state information and the resident 10 position information. The control part 7 may hold | maintain the information of an environmental state, and the positional infomation on the resident 10 inside, and may hold | maintain it at the memory | storage part which is not illustrated in FIG.

  Here, for example, the control unit 7 includes information indicating the relationship between the temperature and humidity in the room and the heat index indicated by the WBGT value, and refers to the information on the environmental state acquired from the environment detection unit 6. Evaluate and record your thermal comfort. FIG. 4 is a diagram illustrating an example of information indicating a relationship between the temperature / humidity included in the control unit 7 of the air conditioner 2 according to Embodiment 1 and the heat index indicated by the WBGT value. The contents of FIG. 4 are the same as the contents of the pamphlet “Let's Prevent Heat Stroke” issued by the Ministry of Health, Labor and Welfare, so detailed description will be omitted. The control unit 7 predicts the thermal comfort in the room by a PMV (Predicted Mean Vote) value including the temperature / humidity, airflow, clothes, work amount, etc. in addition to the method using the WBGT value. An average thermal sensation may be used, and is not limited to these methods.

  The biological information detection unit 3 acquires the biological information of the resident 10. The control unit 7 of the air conditioner 2 acquires the biometric information of the resident 10 from the biometric information detection unit 3 (step S3). The control unit 7 records the acquired biological information. The control part 7 may hold | maintain biometric information inside, and may be hold | maintained at the memory | storage part which is not illustrated in FIG. The biometric information detection unit 3 may transmit biometric information to the control unit 7 when there is an acquisition request from the control unit 7, or may transmit biometric information to the control unit 7 periodically.

  The control part 7 sets the priority of the resident 10 using the resident information of the resident 10 acquired in step S1 (step S4). The control part 7 sets the priority of all the residents 10 when the several residents 10 exist in a living room. The control unit 7 acquires resident information from the biological information detection unit 3 together with the biological information. Since control part 7 has acquired information, such as age, height, weight, and sex, of each resident 10 as resident information, priority of each resident 10 is used using one or more of these information. Set. For example, the control unit 7 sets a higher priority for the resident 10 who is older. Since the control part 7 knows the residence time of the resident 10 according to the period during which the resident information is continuously acquired, the control unit 7 may set a higher priority for the resident 10 having a longer stay period. The control unit 7 may set the priority of the resident 10 by using each information included in the resident information in combination, and the method of setting the priority is not limited to these.

The control unit 7 determines whether or not all the residents 10 are in the comfort area, that is, whether or not the health condition is abnormal, using the biometric information of each of the residents 10 (step S5). For example, the control unit 7 is assumed to store in advance a threshold value of biometric information that allows a healthy or comfortable living. The threshold value is set for each piece of biological information, and is, for example, the skin temperature of the resident 10: 30 to 37 ° C., the heart rate: 60 to 100 bpm, and the sweat rate 1.0 mg / cm ² / min or more. The control unit 7 compares the biometric information acquired for each resident 10 with the threshold, determines that all the items of the biometric information are within the comfortable area, and determines one or more pieces of biometric information. The resident 10 having an item outside the threshold in the item of the item departs from the comfort area, that is, determines that the health condition is abnormal. The control unit 7 determines whether or not all the residents 10 are in the comfort area.

  When there is a resident 10 that has deviated from the comfortable area (step S5: Yes), the control unit 7 uses the environmental state and the biological information of the resident 10 to check the air conditioner 2 for the resident 10 that has deviated from the comfortable area. The air conditioning control content is set (step S6). FIG. 5 is a diagram illustrating a setting example of air conditioning control contents in the control unit 7 of the air conditioner 2 according to Embodiment 1. For example, the control unit 7 determines that the resident 10 whose skin temperature, heart rate, and sweating amount exceed the threshold values feels hot, and the set temperature with respect to the set temperature set by the remote controller or the like. The air-conditioning control content for turning off the air and turning off the air flow is set. This air conditioning control content is the first air conditioning control content. Further, the control unit 7 determines, for example, that the resident 10 whose sweating amount is within the threshold value but whose skin temperature and heart rate are lower than the threshold value feels cold, and with respect to the set temperature set by the remote controller or the like. Set the air conditioning control details to raise the set temperature. This air conditioning control content is set as the second air conditioning control content.

  As a result of setting the air conditioning control content for each resident 10, the control unit 7 confirms whether or not a plurality of air conditioning control content is included (step S7). Specifically, when the air conditioning control content for a plurality of residents 10 is set, the control unit 7 sets the first air conditioning control content for one resident 10 and the second for another resident 10. Check that the air conditioning control details of the are not set. When a plurality of contradictory air conditioning control contents are included (step S7: Yes), the control unit 7 determines the priority of the resident 10 in which the first air conditioning control contents are set, and the second air conditioning. The priority of the resident 10 to which the control content is set is compared, and the air conditioning control content is determined to be the first air conditioning control content or the second air conditioning control content (step S8). That is, when a plurality of air conditioning control details are set for a plurality of residents 10, the control unit 7 changes the air conditioning control details set for the residents 10 with high priority to the air conditioning unit 4 and the wind direction control unit 5. The air conditioning control content for The control unit 7 may, for example, obtain the average of the priorities of the occupants 10 of the groups of the respective air conditioning control contents and adopt the higher air conditioning control contents, or the occupants 10 of the groups of the respective air conditioning control contents. The priority of the residents 10 having the highest priority may be compared, and the air conditioning control content with the higher priority may be adopted.

  When a plurality of air conditioning control details are not included (step S7: No), the control unit 7 determines, that is, adopts the air conditioning control details set for the occupant 10 (step S9). After the process of step S8 or step S9, the control unit 7 instructs the air conditioning unit 4 and the wind direction control unit 5 on the air conditioning control content adopted. The air conditioning unit 4 and the wind direction control unit 5 perform the air conditioning control on the living room with the air conditioning control content determined by the control unit 7 (step S10).

  When there is no resident 10 that has deviated from the comfort area (step S5: No), the control unit 7 determines to maintain the current air conditioning control content (step S11).

  In addition, although the control part 7 has set the priority of all the residents who exist in a living room in step S4, it is not limited to this. In the case of step S7: Yes, the control unit 7 may set the priority of the corresponding resident at the stage before the process of step S8. In this case, since the number of residents who set the priority can be reduced, the processing load of the control unit 7 can be reduced.

  In the environmental control system 1, while the air conditioner 2 is powered on, the process returns to step S1 and the processes from step S1 to step S11 are repeatedly executed. In the environment control system 1, when returning from step S10 to step S1, it is possible to wait for a specified period in consideration of the time until the air conditioning control performed in step S10 is reflected in the living room. There is a possibility that the occupant 10 for whom the air conditioning control content on the side that has not been adopted in step S8 is set temporarily departs from the comfort area. However, as a result of executing the air conditioning control content on the higher priority side, the air conditioner 2 is expected to be within the comfort area, that is, the biological information is within the threshold for the resident 10 for which the air conditioning control content is set. Is done. As a result, in the next processing flow, the control unit 7 is expected to adopt the air conditioning control content on the side that was not adopted last time, from the priority of the resident 10. The air conditioner 2 can improve the comfort of the occupant 10 in the entire living room by repeatedly executing the processing from step S1 to step S11.

  Note that the control unit 7 may cause the occupant 10 to make an abnormality using the reference result with the heat index or the PMV value held in advance for the information on the environmental state from the environment detection unit 6. If it is determined from the biometric information that the resident 10 feels hot despite the small amount, for example, control is performed to lower the set temperature from the current level, or air is blown toward the resident 10. Also good. In addition, the control unit 7 is a mobile terminal that is separately registered when, for example, body movement of the resident 10 is small and skin temperature is high due to biological information from the biological information detection unit 3 and urgent measures such as heat stroke are required. Or you may provide the function to alert | report to a plant | facility.

  Moreover, the control part 7 is not only the skin temperature, the heart rate, and the upper limit value and the lower limit value of the perspiration amount, but also the amount of change at a specified time for the threshold value of the comfort area used for comparison with the biometric information of the resident 10. For example, the determination may be made based on the skin temperature ± Δ ° C. Furthermore, since the comfort area changes depending on the season, the control unit 7 may acquire the season information based on, for example, a calendar or information from the outside, and change the threshold range of the comfort area.

  When a plurality of residents 10 exist in the room, the biological information detection unit 3 worn by each resident 10 transmits the biological information of the resident 10 to the control unit 7. At this time, the biological information detection unit 3 also transmits resident information in which the age, height, weight, sex, and the like of the resident 10 are registered to the control unit 7. Here, the skin temperature, the heart rate, and the amount of perspiration are compared with the biometric information of each resident 10 and the comfort region threshold for determining the health state of the resident 10 is the age, sex, etc. of the resident 10. This is an element whose average value changes. Therefore, the control part 7 may hold | maintain the threshold value of a comfort area | region beforehand with the attribute of the resident | residence 10, such as every age and sex. The control unit 7 determines the health status of the resident 10 by changing the threshold value of the comfort area for each resident 10 according to the age, sex, etc. of the resident 10 obtained from the resident information and comparing it with the biological information. May be.

  In addition, the control unit 7 records the biometric information of the resident 10 when deviating from the comfort area and the biometric information of the resident 10 when there is no abnormality every time the processing from step S1 to step S11, that is, periodically. doing. Therefore, for example, the control unit 7 associates the accumulated biological information with the information on the environmental state detected by the environment detection unit 6, and calculates a heat index or a comfortable predicted value that makes each resident 10 comfortable, It may be updated.

  Moreover, the biometric information detection part 3 transmits the resident information of the resident 10 existing in the room to the air conditioner 2 together with the biometric information, and the control part 7 records the resident information and the biometric information of the resident 10, keeping. Therefore, the control part 7 can recognize the new resident 10 by the process from step S1 to step S3, for example, also when the resident 10 newly enters the living room which the air conditioner 2 controls air conditioning. Air conditioning control can be implemented. On the other hand, for example, when the occupant 10 leaves the room controlled by the air conditioner 2, the control unit 7 leaves the room due to the processing from step S1 to step S3 and the contents recorded so far. Resident 10 can be recognized and air-conditioning control can be implemented.

  As described above, according to the present embodiment, in the environment control system 1, the control unit 7 of the air conditioner 2 sets a priority for the resident 10 existing in the living room, and the priority of the resident 10. It was decided to determine the air conditioning control content. Thereby, the environment control system 1 can improve the comfort of the resident 10 in the whole living room, when the several resident 10 exists in a living room.

In the environmental control system 1, the control unit 7 of the air conditioner 2 performs the operation from step S <b> 1 regardless of whether the air conditioner 2 is turned on or off. Moreover, in the environmental control system 1, even if the air-conditioning part 4 and the wind direction control part 5 are stopping air-conditioning control, the biometric information detection part 3 acquires the biometric information of the resident 10, and the environment detection part 6 The environmental condition and the position of the resident 10 are detected.

  The control part 7 confirms whether the power supply of the air conditioner 2 is turned ON after the process of step S8 or step S9 (step S21). When the power supply of the air conditioner 2 is on (step S21: Yes), the control unit 7 performs the process of step S10 as in the first embodiment. When the power supply of the air conditioner 2 is off (step S21: No), the control unit 7 turns on the power supply of the air conditioner 2 when implementing the determined air conditioning control contents, that is, the air conditioning unit 4 and the wind direction control. The air conditioning control in the unit 5 is started (step S22). The control unit 7 performs the process of step S10 after the process of step S22.

  The control part 7 confirms whether the power supply of the air conditioner 2 was originally turned on after the process of step S10 or step S11 (step S23). When the power supply of the air conditioner 2 was originally turned on (step S23: Yes), that is, in the case of the same processing as in the first embodiment, the control unit 7 returns to step S1 and repeatedly executes the above processing.

  When the power of the air conditioner 2 is originally off (step S23: No), that is, when the power of the air conditioner 2 is turned on in step S22, the control unit 7 turns on the power of the air conditioner 2. Then, it is confirmed whether or not a prescribed time has passed (step S24). In the second embodiment, for example, it is assumed that the occupant 10 is sleeping, and a specified time is provided to avoid a situation in which the air conditioner 2 is kept on. ing. When the prescribed time has not elapsed (step S24: No), the control unit 7 returns to step S1 and repeatedly executes the above processing. When the prescribed time has elapsed (step S24: Yes), the control unit 7 turns off the power of the air conditioner 2 (step S25), returns to step S1, and repeatedly executes the above processing.

  FIG. 7 is a conceptual diagram schematically showing the positional relationship between the environment control system 1a according to the third embodiment and a living room. FIG. 8 is a block diagram illustrating a configuration example of the environmental control system 1a according to the third embodiment. The environment control system 1a includes air conditioners 2a and 8 and a biological information detection unit 3. The air conditioner 2a includes an air conditioning unit 4, a wind direction control unit 5, an environment detection unit 6, and a control unit 7a. The control unit 7a controls the operation of the air conditioner 8 in addition to the function of the control unit 7 of the first and second embodiments. The control part 7a determines the air conditioning control content of the air conditioner 2a and the air conditioner 8 using the priority and the air conditioning control content for each resident 10. The control part 7a shall hold | maintain the information of the relative position of the air conditioner 8 with respect to the air conditioner 2a. The air conditioner 2a is a first air conditioner, and the air conditioner 8 is a second air conditioner.

  The air conditioner 8 is electrically connected to the air conditioner 2a, and controls at least one of the temperature, humidity, and wind speed of the room according to the control of the control unit 7a of the air conditioner 2a. Similarly to the air conditioner 2a, the air conditioner 8 may be configured to include the air conditioning unit 4, the wind direction control unit 5, the environment detection unit 6, and the control unit 7a.

  It continues and the operation | movement in which the air conditioner 2a and the air conditioner 8 of the environmental control system 1a implement air-conditioning control of a living room is demonstrated. FIG. 9 is a flowchart showing the operation of the air conditioner 2a according to the third embodiment. The flowchart showing the operation of the air conditioner 2a according to the third embodiment is different in step S6a from the flowchart of the air conditioner 2 of the first embodiment shown in FIG. In step S6a, the control unit 7a determines the air conditioning control content of the air conditioner 2a for the occupant 10 who has departed from the comfort area, and also determines the air conditioning control content of the air conditioner 8. The control unit 7a determines that air conditioning control is to be performed using at least one of the air conditioner 2a and the air conditioner 8 based on the positional relationship between the air conditioner 2a, the air conditioner 8, and the occupant 10. . For example, when the control unit 7a determines that the value indicated by the biological information of a certain resident 10 deviates from the threshold value of the comfortable area and the resident 10 feels hot, and requires cooling, the corresponding resident 10 The air conditioning control contents in the air conditioner 2a and the air conditioner 8 are determined from the positional relationship between the person 10 and the air conditioner 2a and the positional relationship between the corresponding resident 10 and the air conditioner 8. For example, when the distance between the air conditioner 8 and the resident 10 corresponding to the air conditioner 8 is shorter than that of the air conditioner 2a, the control unit 7a does not perform the air conditioning control in the air conditioner 2a and performs air conditioning on the air conditioner 8. Decide to implement control.

  As described above, according to the present embodiment, the environment control system 1a includes the plurality of air conditioners 2a and 8, and each air conditioner 2a, The air conditioning control content of 8 was decided. Thereby, since the environmental control system 1a can perform air-conditioning control locally with respect to the occupant 10 in need of environmental improvement, even when a plurality of occupants 10 are present in the room, other residences The air conditioning control can be accurately performed while improving the health condition of the person 10 and maintaining a comfortable environmental state.

  The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
