  Hereinafter, a control system according to an embodiment of the present invention and a home controller constituting the control system will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

<System configuration>
FIG. 1 is a diagram for explaining a schematic configuration of the ventilation system 1. FIG. 1A is a diagram illustrating an overview of a house 900 in which the ventilation system 1 is provided. FIG. 1B is a cross-sectional view taken along line Ib-Ib in FIG.

  Referring to FIG. 1B, a house 900 includes at least a concrete foundation 910, a wooden frame 920 installed on the foundation 910, a floor 930, an outer wall 940, an inner wall 950, and a ceiling 960. , And a roof 970. The house 900 includes a room 70 and an underfloor space 80. The room 70 is a space surrounded by a floor 930, an inner wall 950, and a ceiling 960. The underfloor space 80 is a space surrounded by the floor 930 and the foundation 910.

  The ventilation system 1 includes a home controller 10, a human sensor 30, a temperature sensor 40, a temperature sensor 50, and a ventilation device 60. Home controller 10 communicates with human sensor 30, temperature sensor 40, temperature sensor 50, and ventilation device 60. Further, the home controller 10 controls the operation of the ventilation device 60.

  Home controller 10, human sensor 30, and temperature sensor 40 are installed on the wall surface of room 70 (the surface of inner wall 950 opposite to outer wall 940). The temperature sensor 50 is installed in the underfloor space 80.

  The human sensor 30 determines whether there is a person in the room 70. The temperature sensor 40 detects the temperature of the room 70 (hereinafter also referred to as “room temperature”). The temperature sensor 50 detects the temperature of the underfloor space 80. In addition, unless the ventilation mentioned later is performed, the temperature change of the underfloor space 80 is usually smaller than the change of the room temperature. That is, the underfloor space 80 is less susceptible to changes in the outside air temperature than the room 70.

  The ventilation device 60 includes a blower device 61 and a duct 62. The air blower 61 has a ventilation port 61a. The blower 61 is installed in the underfloor space 80. The duct 62 has a ventilation port 62a. The ventilation port 62 a is located on the wall surface of the room 70. The duct 62 has an opening on the side opposite to the ventilation port 62 a connected to the blower 61. The duct 62 is installed over the underfloor space 80 and the space 75 between the outer wall 940 and the inner wall 950.

  The ventilation device 60 performs ventilation between the room 70 and the underfloor space 80. “Ventilation” means replacing air. When receiving a first command from the home controller 10, the ventilator 60 sends the air in the room 70 to the underfloor space 80. When receiving the second command from the home controller 10, the ventilation device 60 sends the air in the underfloor space 80 to the room 70. The blower 61 is, for example, a forward / reverse bidirectional axial fan that can blow forward and backward.

  Hereinafter, an outline of the operation of the ventilation system 1 will be described. For example, in the daytime when the winter weather is good, for example, the sunlight of the sun is inserted into the room 70 through the window 980 (see FIG. 1A). For this reason, room temperature rises. On the other hand, since sunlight does not enter the underfloor space 80, the temperature of the underfloor space 80 does not rise as much as room temperature.

  Therefore, the home controller 10 is ventilated so that warm air in the room 70 is stored in the underfloor space 80 in the daytime, and the air stored in the underfloor space 80 is returned to the room 70 when the room temperature drops, such as evening or night. The device 60 is controlled. The home controller 10 performs the control based on the detection results of the temperature sensor 40 and the temperature sensor 50. By performing such control, the heat stored in the room 70 can be used effectively.

  The home controller 10 further performs different control based on the detection result of the human sensor 30 depending on whether or not there is a person in the room 70. Details of the control will be described later. In addition, the home controller 10 performs control opposite to that in winter in summer. Details of the control will also be described later.

  In FIG. 1, a single house is taken as an example, but it may be a single apartment house such as a condominium. Moreover, it is preferable from a viewpoint of improving energy efficiency that a heat insulating material is affixed on the foundation 910 and the floor 930, and the underfloor space 80 is made into the space enclosed with the heat insulating material.

<Hardware configuration of home controller>
FIG. 2 is a diagram illustrating an appearance of the home controller 10. Referring to FIG. 2, home controller 10 includes operation keys 1071 to 1076 as input devices and a monitor 110.

  FIG. 3 is a diagram for explaining a hardware configuration of the home controller 10. Referring to FIG. 3, home controller 10 includes a CPU (Central Processing Unit) 101 that executes a program, a main storage device 102, a ROM (Read Only Memory) 103 that stores data in a nonvolatile manner, and a flash memory 104. A VRAM (Video Random Access Memory) 105, an input device 107 that receives an instruction input by a user of the home controller 10, a communication interface 108, an IC (Integrated Circuit) card reader / writer 109, and a monitor 110. The home controller 10 has a calendar function and a clock function as in a general computer. Thereby, the home controller 10 can determine the current date and time.

  The flash memory 104 is a nonvolatile semiconductor memory. The VRAM 105 is a memory that holds the contents displayed on the monitor 110. The monitor 110 displays the contents held by the VRAM 105.

  The communication interface 108 communicates with the human sensor 30, the temperature sensor 40, the temperature sensor 50, and the ventilation device 60.

  The constituent elements 101 to 105 and 106 to 109 are connected to each other by a data bus. A memory card 191 is attached to the IC card reader / writer 109.

  The processing in the home controller 10 is realized by each hardware and software executed by the CPU 101. Such software may be stored in the flash memory 104 in advance. The software may be stored in a memory card 191 or other storage medium and distributed as a program product. Alternatively, the software may be provided as a program product that can be downloaded by an information provider connected to the so-called Internet. Such software is read from the storage medium by the IC card reader / writer 109 or other reading device, or downloaded via the communication interface 108 and then temporarily stored in the flash memory 104. The software is read from the flash memory 104 by the CPU 101 and further stored in the flash memory 104 in the form of an executable program. The CPU 101 executes the program.

  Each component which comprises the home controller 10 shown by the figure is a general thing. Therefore, it can be said that an essential part of the present invention is software stored in the flash memory 104, the memory card 191 or other storage medium, or software that can be downloaded via a network. Since the operation of each hardware of home controller 10 is well known, detailed description will not be repeated.

  The recording media are not limited to DVD-ROM, CD-ROM, FD (Flexible Disk), and hard disk, but are magnetic tape, cassette tape, optical disk (MO (Magnetic Optical Disc) / MD (Mini Disc) / DVD (Digital Versatile Disc), optical card, mask ROM, EPROM (Electronically Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), flash ROM, etc. . The recording medium is a non-temporary medium that can be read by the computer.

  The program here includes not only a program directly executable by the CPU but also a program in a source program format, a compressed program, an encrypted program, and the like.

  Next, the program and data stored in the flash memory 104 will be described more specifically. The flash memory 104 stores a control program for controlling the ventilation device 60. The flash memory 104 stores various data such as data generated by the home controller 10 and data acquired from an external device of the home controller 10 in a volatile manner.

  The flash memory 104 stores data acquired from, for example, the human sensor 30, the temperature sensor, the temperature sensor 50, and the like as an external device in a volatile manner. The CPU 101 stores information indicating whether or not a person is present (hereinafter also referred to as “occupation status information”), room temperature information, temperature information of the underfloor space 80, and the like in the flash memory 104.

  Further, the flash memory 104 stores time information indicating a predetermined time. The predetermined time is, for example, 24:00 (midnight) when the day changes.

  Further, the flash memory 104 stores mode information indicating whether the current control mode is set to the winter mode or the summer mode. Whether the home controller 10 is set to the winter mode or the summer mode is determined based on, for example, an input by the user. Alternatively, information indicating a predetermined date may be stored in the flash memory 104, and the control mode may be automatically set by the CPU 101 based on the information. For example, you can set the control program to update the mode information so that it is in the winter mode from October 1 to March 31, and the summer mode from April 1 to September 31. That's fine.

<Control structure in home controller>
Next, processing in the CPU 101 and the communication interface 108 of the home controller 10 will be described with reference to FIGS.

  FIG. 4 is a flowchart showing a flow of processing performed by the home controller 10. Referring to FIG. 4, in step S <b> 2, CPU 101 of home controller 10 reads mode information from flash memory 104. In step S4, the CPU 101 determines whether the current control mode is the winter mode based on the read mode information.

  When CPU 101 determines that it is the winter mode (YES in step S4), it executes winter processing in step S6. On the other hand, when CPU 101 determines that it is not in the winter mode (NO in step S4), it executes summer processing in step S8.

  FIG. 5 is a flowchart showing details of the process in step S6 in FIG. Referring to FIG. 5, in step S <b> 602, CPU 101 acquires occupancy status information from human sensor 30. The CPU 101 stores the acquired occupancy status information in the flash memory 104. In step S <b> 604, the CPU 101 acquires room temperature information from the temperature sensor 40 and acquires temperature information of the underfloor space 80 from the temperature sensor 50. The CPU 101 stores the acquired information on each temperature in the flash memory 104.

  In step S <b> 606, the CPU 101 determines whether there is a person in the room 70 based on the occupancy status information stored in the flash memory 104. When CPU 101 determines that there is a person (YES in step S606), it determines whether or not the room temperature is higher than the temperature of underfloor space 80 in step S608.

  If CPU 101 determines that the value is high (YES in step S608), in step S610, it transmits a command (first command) for sending air in room 70 to underfloor space 80 to ventilator 60. The command includes a command to operate the ventilator 60 for a predetermined time t1 (for example, 1 minute). If CPU 101 determines that it is not high (NO in step S608), the process proceeds to step S618.

  When CPU 101 determines that there is no person (NO in step S606), it determines whether or not the room temperature is lower than the temperature of underfloor space 80 in step S612. When determining that the CPU 101 is low (YES in step S612), in step S614, the CPU 101 transmits a command (second command) for sending the air in the underfloor space 80 to the room 70 to the ventilation device 60. The command includes a command to operate the ventilator 60 for a predetermined time t2 (for example, 30 minutes). After operating the ventilator 60 for the commanded time t2, the CPU 101 puts the ventilator 60 in a standby state until the time indicated by the time information stored in the flash memory 104 is reached in step S616. That is, the CPU 101 transmits a command to stop the operation of the ventilation device 60 to the ventilation device 60.

  If CPU 101 determines that the value is not low (NO in step S612), the process proceeds to step S618. In step S618, the CPU 101 determines whether or not the control mode has been changed. That is, the CPU 101 determines whether or not the control mode has been changed from the winter mode to the summer mode. If CPU 101 determines that the change has been made (YES in step S618), the process proceeds to step S8 in FIG. If CPU 101 determines that it has not been changed (NO in step S618), it determines in step S620 whether or not an input for turning off power to home controller 10 has been received via input device 107.

  If CPU 101 determines that it has been accepted (YES in step S620), it terminates the winter process. If CPU 101 determines that it has not been accepted (NO in step S620), the process proceeds to step S602.

  FIG. 6 is a flowchart showing details of the process in step S8 in FIG. Referring to FIG. 6, in step S <b> 802, CPU 101 acquires occupancy status information from human sensor 30. The CPU 101 stores the acquired occupancy status information in the flash memory 104. In step S <b> 804, the CPU 101 acquires room temperature information from the temperature sensor 40 and acquires temperature information of the underfloor space 80 from the temperature sensor 50. The CPU 101 stores the acquired information on each temperature in the flash memory 104.

  In step S <b> 806, the CPU 101 determines whether there is a person in the room 70 based on the occupancy status information stored in the flash memory 104. When CPU 101 determines that there is a person (YES in step S806), it determines whether or not the room temperature is lower than the temperature of underfloor space 80 in step S808.

  If it is determined that the CPU 101 is low (YES in step S808), in step S810, a command (first command) for sending air in the room 70 to the underfloor space 80 is transmitted to the ventilation device 60. The command includes a command for operating the ventilation device 60 for a predetermined time t3 (for example, 1 minute). If CPU 101 determines that the value is not low (NO in step S808), the process proceeds to step S818.

  When CPU 101 determines that there is no person (NO in step S806), it determines whether or not the room temperature is higher than the temperature of underfloor space 80 in step S812. When CPU 101 determines that the value is high (YES in step S812), in step S814, it transmits a command (second command) for sending air in underfloor space 80 to room 70 to ventilator 60. The command includes a command for operating the ventilation device 60 for a predetermined time t4 (for example, 30 minutes). After operating the ventilator 60 for the commanded time t4, the CPU 101 places the ventilator 60 in a standby state until the time indicated by the time information stored in the flash memory 104 is reached in step S816. That is, the CPU 101 transmits a command to stop the operation of the ventilation device 60 to the ventilation device 60.

  If CPU 101 determines that the value is not high (NO in step S812), the process proceeds to step S818. In step S818, the CPU 101 determines whether or not the control mode has been changed. That is, the CPU 101 determines whether or not the control mode has been changed from the summer mode to the winter mode. If CPU 101 determines that the change has been made (YES in step S818), the process proceeds to step S6 in FIG. If CPU 101 determines that it has not been changed (NO in step S818), it determines in step S820 whether an input to turn off power to home controller 10 has been received via input device 107.

  When CPU 101 determines that it has been received (YES in step S820), it ends the summer process. If CPU 101 determines that it has not been received (NO in step S820), the process proceeds to step S802.

  (1) As described above, when the control mode is the winter mode, the CPU 101 determines that the temperature of the room 70 is higher than the temperature of the underfloor space 80, and uses the communication interface 108 to change the ventilation device 60. To control the air in the room 70 to be sent to the underfloor space 80. Further, based on the determination that the temperature of the room 70 is lower than the temperature of the underfloor space 80, the CPU 101 controls the ventilation device 60 to send the air in the underfloor space 80 to the room 70 using the communication interface 108. .

  Therefore, in the ventilation system 1, the air in the room 70 can be stored in the underfloor space 80 when the room temperature is higher than the temperature of the underfloor space 80 during the daytime or the like. Further, when the room temperature becomes lower than the temperature of the underfloor space 80 in the evening or at night, the air of the underfloor space 80 stored during the day can be sent to the room 70. Therefore, the ventilation system 1 can efficiently use the heat stored in the room 70 during the day.

  Specifically, when the control mode is the winter mode, the CPU 101 determines that the temperature of the room 70 is lower than the temperature of the underfloor space 80 and determines that the person is in the room 70. Control is performed to send the air in the underfloor space 80 to the room 70.

  That is, the CPU 101 does not return the warm air in the underfloor space 80 to the room 70 when there is no person in the room 70. Therefore, the ventilation system 1 can use the heat stored in the room 70 during the day more efficiently.

  More specifically, when the control mode is the winter mode, the CPU 101 determines that the temperature of the room 70 is higher than the temperature of the underfloor space 80, and determines that there is no person in the room 70. 60 is controlled to send the air in the room 70 to the underfloor space 80.

  That is, the CPU 101 does not perform control to send air in the room 70 to the underfloor space 80 when there is a person in the room 70 even when the temperature of the room 70 is higher than the temperature of the underfloor space 80. Therefore, the ventilation system 1 can raise room temperature compared with the case where the air of the room 70 is sent to the underfloor space 80. Therefore, in the ventilation system 1, the room 70 can be made more comfortable for the user than when the air in the room 70 is sent to the underfloor space 80.

  (2) When the control mode is the summer mode, the CPU 101 causes the ventilator 60 to send the air in the room 70 to the underfloor space 80 based on determining that the temperature of the room 70 is lower than the temperature of the underfloor space 80. Take control. Further, the CPU 101 controls the ventilation device 60 to send the air in the underfloor space 80 to the room 70 based on the determination that the temperature of the room 70 is higher than the temperature of the underfloor space 80.

  Therefore, in the ventilation system 1, when the room temperature is lower than the temperature of the underfloor space 80 at night or early morning, the air in the room 70 can be stored in the underfloor space 80. Further, when the room temperature becomes higher than the temperature of the underfloor space 80 in the daytime or the like, the air in the underfloor space 80 stored in the night or early morning can be sent to the room 70. Therefore, the ventilation system 1 can efficiently use the cold air stored in the room 70 in the middle of the night or early morning.

  Specifically, when the control mode is the summer mode, the CPU 101 determines that the temperature of the room 70 is higher than the temperature of the underfloor space 80 and determines that the person is in the room 70, and the ventilation device 60 Control is performed to send air in the underfloor space 80 to the room 70.

  That is, the CPU 101 does not return the cold air in the underfloor space 80 to the room 70 when there is no person in the room 70. Therefore, in the ventilation system 1, the cooler stored in the room 70 in the night or early morning can be used more efficiently.

  More specifically, when the control mode is the summer mode, the CPU 101 determines that the temperature of the room 70 is lower than the temperature of the underfloor space 80 and determines that the person is not in the room 70. 60 is controlled to send the air in the room 70 to the underfloor space 80.

  That is, the CPU 101 does not perform control to send air in the room 70 to the underfloor space 80 when there is a person in the room 70 even when the temperature of the room 70 is lower than the temperature of the underfloor space 80. Therefore, the ventilation system 1 can suppress an increase in room temperature as compared with the case where the air in the room 70 is sent to the underfloor space 80. Therefore, in the ventilation system 1, the room 70 can be made more comfortable for the user than when the air in the room 70 is sent to the underfloor space 80.

<Modification>

When there are a plurality of rooms, the house 900 and the ventilation system 1 may be configured so that ventilation between each room and the underfloor space 80 is possible.

  Moreover, in such a structure, you may comprise the ventilation system 1 so that it can set whether ventilation is performed for every room. For example, a mechanism for controlling the air flow between the ventilation device 60 and the room may be provided in each duct connecting the ventilation device 60 and each room, and the home controller 10 may control the operation of the mechanism.

  The home controller 10 may determine in which room ventilation is performed based on, for example, a user setting. Or you may comprise the home controller 10 so that it may determine based on the log | history of the detection result of the human sensitive sensor 30 provided in each room. For example, the home controller 10 may be configured so as not to ventilate the room from the underfloor space 80 in a room where there are no more than a certain percentage of people on a winter night. That is, the home controller 10 may determine the presence or absence of ventilation in each room according to the life pattern based on the detection result of the human sensor 30.

  (2) In the above description, the ventilation system 1 includes the human sensor 30 as an example, but the human sensor 30 is not necessarily required. For example, the home controller 10 may determine whether there is a person in the room 70 based on a user input. For example, when the user presses an outing button provided on the home controller 10 when going out, it is determined that there is no person in the room 70, and when the user returns, the room button is provided on the home controller 10. The home controller 10 may be configured to determine that there is a person at 70.

  Further, the home controller 10 may be configured to determine whether or not there is a person in the room 70 based on the history of detection results of the human sensor 30.

  (3) Moreover, it is preferable to install an ion generator for generating plasma cluster ions in the underfloor space 80. Since the underfloor space 80 is less likely to circulate air than the room 70, viruses and fungi are more likely to be generated than the room 70. For this reason, it becomes possible to send the air after sterilization to the room 70 by generating plasma cluster ions by the ion generator.

  The timing for generating plasma cluster ions is not particularly limited. However, sterilization is preferably performed before the air in the underfloor space 80 is returned to the room 70.

  (4) For example, when adapting the ventilation system 1 to an apartment house such as an apartment, the underfloor space may be a space between the floor of the room and the ceiling of the room on the next lower floor, Alternatively, it may be a space between the ceiling of the room and the floor of the room on the upper floor.

  (5) Moreover, although the structure which makes the ventilation apparatus 60 operate only for the predetermined time t1 (for example, 1 minute) by step S610 of FIG. 5 was mentioned as an example, it is not limited to this. The home controller 10 may be configured to operate the ventilator until the room temperature and the temperature of the underfloor space 80 become the same. The same applies to step S614 in FIG. 5, step S810 in FIG. 6, and step S814 in FIG.

  The embodiment disclosed this time is an exemplification, and the present invention is not limited to the above contents. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
