  Hereinafter, an embodiment in which the technical idea of the present invention is applied to an environment control system for the purpose of preparing the environment of a space (residential space) in a detached house will be described. However, the building is not limited to a detached house, and for example, the environmental control system of the present embodiment can be installed in a dwelling unit of an apartment house or a room of an office building.

(Embodiment 1)
A system configuration diagram of this embodiment is shown in FIG. The outdoor shading device 2 is installed outside the window (lighting unit W1) of the house H, and the indoor shading device 3 is installed inside (indoor side) the lighting unit W1. The outdoor light-shielding device 2 and the indoor light-shielding device 3 are so-called electric blind shutters, and external light (mainly sunlight) that enters the space (residential space) in the building through the daylighting portion W1 provided in the building (house H). ) Is adjusted. In other words, in this embodiment, the outdoor light shielding device 2 and the indoor light shielding device 3 constitute an incident amount adjusting device.

  A ventilation device 4 is installed inside the ventilation window W2 of the house H. A ventilation window W <b> 3 that opens and closes in conjunction with the ventilation device 4 is provided on the ceiling of the house H. That is, when the ventilator 4 is in operation, the ventilation window W3 is opened, air outside the house H (outside air) is introduced into the living space, and air in the living space is discharged to the outside through the ventilation window W3 (exhaust). (See solid arrow in FIG. 1). When the ventilation device 4 is not operating, the ventilation window W3 is also closed.

  Moreover, the lighting fixture (lighting device) 5 and the air conditioner (air conditioner) 6 are installed in the living space. The illumination device 5 includes an electrical light source such as a fluorescent lamp, an incandescent lamp, and a light emitting diode, a lighting circuit that lights the light source, and an illuminance sensor that detects ambient illuminance. The lighting circuit automatically adjusts the light amount of the light source so that the ambient illuminance detected by the illuminance sensor matches the target value, and turns on and off the light source according to the user's operation as described later. However, since this type of illumination device 5 is well known in the art, the detailed illustration and description thereof will be omitted. The air conditioner 6 includes a conventionally known air conditioner and has a function of adjusting the temperature so that the temperature of the living space (indoor temperature) detected by the temperature sensor matches the set temperature.

  Temperature sensors (temperature detection devices) 7 and 8 are installed outside and inside the house H, respectively. The temperature sensor 7 detects the temperature outside the house H (outside air temperature) periodically (for example, at an interval of 1 minute) and outputs the detection result (temperature data of the outside air temperature) to the control device 1. On the other hand, the temperature sensor 8 periodically detects the temperature (indoor temperature) in the house H (residential space) and outputs the detection result (temperature data of the indoor temperature) to the control device 1. To do. That is, in this embodiment, the temperature detection device is configured by the two temperature sensors 7 and 8. However, since such temperature sensors 7 and 8 are well known in the art, illustration and description of a detailed configuration are omitted.

  The control device 1 includes a sensor information acquisition unit 10, a control signal transmission unit 11, a storage unit 12, a control pattern determination unit 13, and a brightness detection unit 14. For example, the distribution device for a house installed in the house H It is stored in a box of a board (not shown). However, only the brightness detection unit 14 for detecting the brightness (illuminance) outside the house H is installed outside the house H. The brightness detection unit 14 periodically detects the brightness outside the house H.

  The sensor information acquisition unit 10 includes two types of temperature data (outside temperature and indoor temperature data) output from the two temperature sensors 7 and 8 and brightness data (illuminance data) detected by the brightness detection unit 14. ) And the obtained data are passed to the control pattern determination unit 13. That is, in this embodiment, the sensor information acquisition unit 10 corresponds to a temperature information acquisition unit. The control signal transmission unit 11 transmits a control signal to the outdoor light shielding device 2, the indoor light shielding device 3, and the ventilation device 4 via the signal line Ls. However, the transmission medium of the control signal is not limited to the signal line Ls, and may be a wireless medium such as radio waves or infrared rays.

  The storage unit 12 includes a rewritable nonvolatile semiconductor memory such as a flash memory, and stores a plurality of types of incident amount adjustment and ventilation adjustment control patterns. The control pattern determination unit 13 determines one of the control patterns stored in the storage unit 12 based on the temperature data of the outside air temperature and the indoor temperature acquired by the sensor information acquisition unit 10. In addition, a control signal corresponding to the determined control pattern is generated and transmitted from the control signal transmission unit 11. Note that such a control pattern determination unit 13 is realized, for example, by causing a microcomputer to execute a dedicated program.

  Here, a plurality of types of control patterns stored in the storage unit 12 will be described. As shown in FIG. 2, the first quadrant of a two-dimensional orthogonal coordinate system in which the outside temperature detected by the temperature sensor 7 is the horizontal axis (x axis) and the indoor temperature detected by the temperature sensor 8 is the vertical axis (y axis). Are divided into four areas R1 to R4 by four straight lines (boundary lines) L1 to L4. Note that the origin O of the two-dimensional orthogonal coordinate system shown in FIG. 2 is not necessarily 0 ° C. In the illustrated example, the four boundary lines L1 to L4 are represented by linear functions of y = x + A, x = B, x = C, and x = D, respectively. Then, among the regions on the left side of the third boundary line L3, the region above the first boundary line L1 and on the right side of the second boundary line L2 is defined as the second area R2, and the remaining region is defined as the first region. Area R1. Of the region on the right side of the third boundary line L3, the region above the first boundary line L1 and on the left side of the fourth boundary line L4 is the third area R3, and the remaining regions are the first region. 4 area R4. A control pattern is assigned to each of these four areas R1 to R4 (see FIG. 3).

  FIG. 3 is a table showing the four areas R <b> 1 to R <b> 4, the control patterns, and the control contents of the individual control patterns, and these tables are stored in the storage unit 12. There are basically four types of control patterns depending on the presence / absence of “use of outside light” and “use of outside air”. For example, in the first and second areas R1, R2 where the outside air temperature is relatively low, control is performed in the direction of increasing the temperature of the living space by using outside light. In the fourth areas R3 and R4, it is desirable to control to reduce the indoor temperature of the living space by not using (shielding) outside light. In the second and third areas R2 and R3, where the temperature of the living space (indoor temperature) is relatively high, it is desirable to control the indoor temperature of the living space to be lowered using the outside air. However, the use of outside light is limited to the time zone from sunrise to sunset, and in particular, it is not preferable from the viewpoint of crime prevention to open the outdoor shading device 2 having a window glass protection function, so other than the time zone from sunrise to sunset The control pattern does not use outside light in the time zone. FIG. 3A shows a control pattern table in a time zone from sunrise to sunset (hereinafter referred to as “daytime time zone”), and FIG. 3B shows a time zone other than the daytime time zone. 2 shows a control pattern table.

  As shown in FIG. 3, the outdoor light shielding device 2 and the indoor light shielding device 3 are both in the “open” state in the control pattern with the use of external light, and the outdoor light shielding device 2 and the indoor light are used in the control pattern without the use of external light. Both light-shielding devices 3 are in a “closed” state. However, the adjustment of the amount of incident external light by the outdoor light-shielding device 2 and the indoor light-shielding device 3 is not limited to two ways of open (100%) and closed (0%). For example, depending on the slat angle of the blind It is also possible to finely adjust the incident amount such as 75%, 50%, 25%.

  In the control pattern with the use of outside air, the ventilation device 4 is turned on (operated) and the ventilation window W3 is set to the “open” state. With the control pattern without the use of outside air, the ventilation device 4 is turned off (stopped) and ventilation is performed. The window W3 is set to the “closed” state. However, the control of the ventilator 4 is not limited to ON / OFF, and the air volume and direction can be finely adjusted.

  Next, the operation of the control device 1 will be described. The control pattern determination unit 13 receives each data of the outside air temperature, the indoor temperature, and the outdoor illuminance from the sensor information acquisition unit 10 at a constant cycle (for example, several minutes to several tens of minutes) and is stored in the storage unit 12. The optimum control pattern corresponding to each received data is determined with reference to the table. Here, the “optimal control pattern” means that the brightness of the living space and the indoor temperature are within a desired range (for example, a range in which the user in the living space does not feel uncomfortable) and the lighting device 5 and The energy consumed by the air conditioner 6 can be reduced, and is stored in the storage unit 12 as the table shown in FIG. 3 as described above.

  First, the control pattern determination unit 13 determines whether or not it is a daytime time zone based on outdoor illuminance data, and if it is a daytime time zone, refer to the table shown in FIG. If not, the table shown in FIG. For example, when the temperature data set of the outside air temperature and the indoor temperature is in the second area R2 in the daytime time zone, the control pattern determination unit 13 uses the daytime time zone shown in FIG. With reference to the table, a control pattern (control pattern with outside use / with outside air use) corresponding to the second area R2 is selected (determined). Furthermore, the control pattern determination unit 13 generates a control signal for opening the outdoor light-shielding device 2 and the indoor light-shielding device 3 according to the determined control pattern, and generates a control signal for turning on (operating) the ventilation device 4. The generated control signal is transmitted from the control signal transmission unit 11 to the light shielding devices 2 and 3 and the ventilation device 4.

  As described above, in the environmental control system of the present embodiment, the control pattern determination unit 13 is stored in the storage unit 12 based on the detection results of the two types of temperatures (outside temperature and indoor temperature) acquired by the sensor information acquisition unit 10. A control signal corresponding to the determined control pattern is generated from a plurality of types of control patterns, and an incident amount adjusting device (outdoor light shielding device 2 and indoor light shielding device 3) and ventilation device are generated. Therefore, a comfortable environment can be maintained while reducing energy consumption using outside light and outside air.

  By the way, as shown in FIG. 4A, the indoor temperature in the dwelling unit H rises and falls in a short time according to the increase / decrease in the incident amount by the light shielding devices 2 and 3 and the increase / decrease in the ventilation by the ventilation device 4. There are cases where the set of temperature data frequently moves in two areas (the first area R1 and the second area R2 in the illustrated example) (see the solid line A in FIG. 4A). In such a case, if the control pattern determination unit 13 changes the control patterns corresponding to the two areas in a short period of time, the life of the light shielding devices 2 and 3 and the ventilation device 4 may be shortened or the operation of each device may be performed. There is a risk that the sound may be uncomfortable.

  Therefore, in order to avoid such a phenomenon (so-called hunting phenomenon), it is desirable that the control pattern determination unit 13 performs the following processing. For example, when the set of temperature data of the outside air temperature and the indoor temperature is in the second area R2, and the indoor temperature is lowered and exceeds the first boundary line L1 when the ventilator 4 is on (operating) Is assumed (see FIG. 4B). At this time, if the difference between the outside air temperature immediately before exceeding the first area R1 and the outside air temperature immediately after exceeding the first area R1 is ± 2 ° C. or more, the control pattern determination unit 13 determines from the control pattern corresponding to the second area R2. The ventilator 4 is turned off (stopped) by changing to the control pattern corresponding to the first area R1. On the other hand, when the difference is less than ± 2 ° C., the indoor temperature immediately after exceeding the first boundary line L1 is the boundary line L1 translated from the first boundary line L1 by −1 ° C. in the y-axis direction. If it is below ', the control pattern determination unit 13 changes the control pattern corresponding to the second area R2 to the control pattern corresponding to the first area R1, and turns off (stops) the ventilator 4. However, if the indoor temperature immediately after exceeding the first area R1 is above the boundary line L1 ′, the control pattern determination unit 13 continues to turn on (operate) the ventilator 4 without changing the control pattern. (Refer to the solid line B in FIG. 4B).

  Or the control pattern determination part 13 may process as follows. A set of temperature data of the outside air temperature and the indoor temperature is changed from the first area R1 to the second area R2 until a predetermined time (for example, 30 minutes) elapses after the ventilation device 4 is turned on (operated). When is changed, the ventilator 4 is not turned off (stopped). If the indoor temperature is lower than the boundary line L1 ′ after a predetermined time has elapsed, the control pattern determination unit 13 changes the control pattern corresponding to the second area R2 to the control pattern corresponding to the first area R1. Change to turn off (stop) the ventilator 4. However, if the indoor temperature is above the boundary line L1 'after a predetermined time has elapsed, the control pattern determination unit 13 continues to turn on (operate) the ventilation device 4 without changing the control pattern. In addition, it is desirable to implement the countermeasure against the hunting phenomenon not only for the ventilation device 4 but also for the incident amount adjusting device (the outdoor light shielding device 2 and the indoor light shielding device 3).

  By the way, although the illuminating device 5 and the air conditioner 6 are automatically controlling the output according to the illuminance and temperature detected by their own sensors, the control device 1 may control the illuminating device 5 and the air conditioner 6. For example, when the outdoor light-shielding device 2 and the indoor light-shielding device 3 are switched from closed to open by performing control with use of external light, the control device 1 performs control if the ambient illuminance detected by the illuminance sensor of the illumination device 5 increases. If the light output of the illuminating device 5 is reduced by transmitting a signal (dimming signal) and the ambient illuminance does not increase, the light output of the illuminating device 5 is not changed without transmitting the control signal. In this case, the detection result (ambient illuminance) of the illuminance sensor is transmitted from the illumination device 5 to the control device 1 via the signal line Ls. Alternatively, when the ventilation device 4 is switched from off (stop) to on (operation) by controlling the use of outside air, a control signal is transmitted from the control device 1 when the temperature detected by the temperature sensor of the air conditioner 6 decreases. If the set temperature of the air conditioner 6 is increased and the temperature does not decrease, the control temperature is not transmitted and the set temperature of the air conditioner 6 is not changed. In this case, the detection result (indoor temperature) of the temperature sensor is transmitted from the air conditioner 6 to the control device 1 via the signal line Ls. The control contents of the lighting device 5 and the air conditioner 6 are included in the control pattern.

  By the way, the temperature change in the living space due to the use of outside air varies depending on the building. For example, if a house H with a high heat insulating effect is compared with a house H with a low heat insulating effect, the house H with a high heat insulating effect is considered to have a larger temperature change in the living space due to the use of outside air. Therefore, the control device 1 may be provided with a control pattern changing unit (not shown) that changes part or all of the control pattern according to a predetermined condition. This control pattern changing unit, for example, does not change the indoor temperature after executing the control with respect to the indoor temperature before executing the control using only the outside air, or reverses the direction in which the direction of the change is assumed ( For example, the control pattern is changed by translating the first boundary line L1 toward the higher indoor temperature. If the control pattern is changed in accordance with the building conditions in this way, it is possible to perform energy-saving control without difficulty according to the actual temperature conditions in each building.

  Further, the control pattern changing unit may change the control pattern according to the operation history in which the incident amount adjusting device and the ventilation device 4 are manually operated. In the present embodiment, as shown in FIG. 1, an operating device 9 is provided that switches between opening and closing (running / stopping) of the outdoor light shielding device 2 and the indoor light shielding device 3 by manual operation. The operation device 9 accepts an operation input by the user and transmits a control signal corresponding to the accepted operation input to manually switch the outdoor light shielding device 2 and the indoor light shielding device 3 to open / close (run / stop). Yes. And the control signal transmitted to the outdoor light-shielding device 2 and the indoor light-shielding device 3 from the operating device 9 is acquired by the sensor information acquisition unit 10 of the control device 1, and the control pattern change unit acquires the control acquired by the sensor information acquisition unit 10. The control pattern is changed based on the content of the signal, that is, the history of manual operation by the operation device 9.

  The processing of the control pattern changing unit will be specifically described with reference to the flowchart shown in FIG. First, the control pattern changing unit initializes the variable n to zero. Then, after the outdoor light-shielding device 2 and the indoor light-shielding device 3 are controlled to be in an open state according to the control pattern determined by the control pattern determination unit 13, the sensor information acquisition unit 10 receives a control signal (operation history) from the operation device 9. get. The control pattern changing unit waits until N minutes elapses after the sensor information acquisition unit 10 acquires the operation history, and after N minutes elapses, the sensor information acquisition unit 10 displays the operation states of the outdoor light shielding device 2 and the indoor light shielding device 3. Get in. If the operation state acquired at this time matches the operation state before N minutes have elapsed, the control pattern changing unit does not change the control pattern. On the other hand, if the operation states do not match, it is determined whether or not the variable n is greater than 1. If the variable n is not greater than 1, the variable n is incremented by 1, and the process returns to the control process using the control pattern. Here, if the variable n is larger than 1, it is considered that the opening operation of the outdoor light shielding device 2 and the indoor light shielding device 3 by the control pattern is rejected by the user, and the control pattern changing unit changes the control pattern.

  If the control pattern is changed according to the operation history of the user as described above, the environment can be adjusted to be more comfortable for the user. However, when energy saving cannot be achieved by changing the control pattern based on the operation history, it is desirable that the control pattern changing unit automatically change the control pattern after a certain period of time to save energy.

  By the way, it is difficult to judge a person's thermal sensation of being hot or cold based only on the outside temperature or the indoor temperature. In other words, there are seasons where the same temperature is felt cold, and there are seasons where it is felt hot, and it is impossible to simply judge the thermal sensation of human beings based on temperature alone, ignoring the season.

  Therefore, the control pattern for each season is stored in the storage unit 12 and the control device 1 includes a timer (clock), and the control pattern determination unit 13 specifies the date from the time counted by the timer, and from this date If the season (spring, summer, autumn and winter) is judged and the control pattern for each season is determined (selected), the environment of the living space can be controlled in a more comfortable state.

(Embodiment 2)
FIG. 6 shows a system configuration diagram of this embodiment. The present embodiment is characterized in that it includes a center device S that performs data communication with a plurality of (only one is shown in FIG. 6) control devices 1 installed in different buildings. However, since the basic configuration of this embodiment is the same as that of the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

  The control device 1 in this embodiment includes a data communication unit 15 and a control pattern acquisition unit 16. The data communication unit 15 is connected to the Internet via a communication medium such as a public line or an optical fiber, and performs data communication with the center device S through the Internet (not shown). In addition, the control pattern acquisition unit 16 transmits the information of the area to which the building belongs to the center device S from the data communication unit 15 and receives the control pattern returned from the center device S by the data communication unit 15. The control pattern thus stored is stored in the storage unit 12. In addition, the information of the area to which the location of the building belongs is manually input to the control device 1 by the contractor or acquired by the GPS receiver provided in the control device 1.

  On the other hand, when the center device S receives the region information from the control device 1, the center device S selects one or more types of control patterns suitable for the region and returns them to the control device 1. The control pattern possessed by the center device S is a control pattern suitable for a warm region, a control pattern suitable for a cold region, or the like. For example, a person living in a cold area is used to cold compared to a person living in a warm area, but is not used to heat, so the second to fourth boundary lines L2 to L4 in FIG. It is desirable to move in the direction approaching the y-axis (the direction in which the outside air temperature decreases).

  Thus, one or more types of control patterns suitable for the area information received by the center device S from the control device 1 are selected and returned to the control device 1, and the control pattern acquisition unit 16 of the control device 1 receives the information from the center device S. Since the received control pattern is stored in the storage unit 12, there is an advantage that it is possible to control with a control pattern suitable for each region and the usability is improved.
