The control device 10 may also have an input/output interface (not shown) for connecting a recording medium such as a USB memory. In this case, the recording medium may store a control program executed by the CPU 101. good.

In addition to the boot program, the ROM 102 stores information unique to the control device 10 (such as an identification number) and fixed values that do not change.

Accordingly, the control system 100 can be constructed using various illuminance sensors 12, human sensors 14, and temperature sensors 16 manufactured by different manufacturers.

The hardware configuration of the management device 18 shown in FIG. 1 may be the same as in FIG. However, the management device 18 may not include the wireless module 104, the antenna interface 105 and the antenna 106, and may be provided with an HDD instead of the SSD.

When the human sensor 14 detects the absence of a person in the living room 300, the second control unit 202 reduces the amount of light output by the lighting 22 (that is, the dimming rate) in order to reduce the power consumption of the lighting 22. You may output the 1st instruction|indication which shows an amount to the 1st control part 201. FIG. In addition, when the human sensor 14 detects the absence of a person in the living room 300, the second control unit 202 changes the amount of change in the set temperature of the air conditioner 24 in order to reduce the power consumption of the air conditioner 24. 1 instruction may be output to the first control unit 201 . The amount of change in the set temperature is a negative value for heating and a positive value for cooling.

It should be noted that, when external light correction interlocking, which will be described later, is set to a valid state, the second control unit 202 does not have to perform the operation of outputting the first instruction based on the detection of the absence of a person. Instead of outputting the first instruction, the second control unit 202 outputs the third instruction indicating the light amount (dimming rate) of the lighting 22 that makes the illuminance constant based on the illuminance detected by the illuminance sensor 12 as the first control. You may output to the part 201. FIG.

Further, when temperature interlocking, which will be described later, is set to a valid state, the second control unit 202 does not have to perform the operation of outputting the first instruction based on the detection of the absence of a person. Instead of outputting the first instruction, the second control unit 202 first outputs a sixth instruction indicating the amount of change in the set temperature of the air conditioner 24 calculated based on the temperature of the room 300 detected by the temperature sensor 16. You may output to the control part 201. FIG.

The third control unit 203 reduces the amount of light (dimming rate) output by the lighting 22 in order to reduce the power consumption of the lighting 22 when the predicted value of the power consumption consumed in the living room 300 exceeds the target power. A second instruction indicating the amount may be output to the first control unit 201 . Further, when the predicted value of the power usage amount consumed in the living room 300 exceeds the target power, the third control unit 203 changes the amount of change in the set temperature of the air conditioner 24 in order to reduce the power consumption of the air conditioner 24. You may output the 2nd instruction|indication which shows to the 1st control part 201. FIG. The amount of change in the set temperature is a negative value for heating and a positive value for cooling. Note that the third control unit 203 may change the amount of change indicated by the second instruction for each level of a plurality of alarms generated according to the amount of excess of the predicted value over the target power.

Further, when the set temperature change mode is set as the operation mode on the demand control setting screen shown in FIG. 2 instructions may be output to the first control unit 201 . Demand control is control of the lighting 22 and the air conditioner 24 according to the alarm level when the predicted value of the power consumption of the living room 300 exceeds the target power and an alarm is issued.

When the fan mode is set as the operation mode, the third control unit 203 may output to the first control unit 201 a fourth instruction indicating a change to the fan mode. When the power supply is set to be disabled on the demand control setting screen, the third control unit 203 may output to the first control unit 201 a fifth instruction to stop the air conditioner 24 .

The first control unit 201 controls operations of the lighting 22 and the air conditioner 24 based on a preset operation schedule of the lighting 22 and the air conditioner 24 . The first control unit 201 sets a setting value (for example, Dimming ratio) may be calculated and the calculated setting may be set for the lighting. When receiving the third instruction, the first control unit 201 may set the light amount (dimming rate) output by the lighting 22 to the light amount indicated by the third instruction instead of the light amount set in the driving schedule. good.

In addition, the first control unit 201 sets the set value for the air conditioner 24 based on the set value (for example, the set temperature) of the air conditioner 24 set in the operation schedule, the first instruction, and the second instruction. (For example, the set temperature) may be calculated and the calculated setting may be set in the air conditioner 24 .

Alternatively, when the first control unit 201 receives the second instruction from the third control unit 203 during the manual mode in which the operation of the lighting 22 or the air conditioner 24 is controlled under conditions different from the operation schedule, the manual mode is canceled. You may Then, the first control unit 201 shifts to control based on the operation schedule, and controls the lighting 22 based on the set value of the lighting 22 or the air conditioner 24 set in the operation schedule, the first instruction, and the second instruction. Alternatively, setting values to be set in the air conditioner 24 may be calculated.

When the first control unit 201 receives the fourth instruction or the fifth instruction, the first control unit 201 may change the setting of the air conditioner 24 based on the fourth instruction or the fifth instruction regardless of the first instruction. Furthermore, the first control unit 201 sets the set value for the air conditioner 24 based on the set value (for example, the set temperature) of the air conditioner 24 set in the operation schedule, the second instruction, and the sixth instruction. (For example, the set temperature) may be calculated and the calculated setting may be set in the air conditioner 24 .

Examples of the operation of the control device 10, including the first control section 201, the second control section 202 and the third control section 203, are described in FIGS. 6, 9, 10 and 14-16.

FIG. 5 is an explanatory diagram showing an example of a setting screen for the operation schedule of the lighting 22 of FIG. The setting screen shown in FIG. 5 is managed by the management device 18 and displayed on the display of the terminal device 34 by cloud computing. Each item of the driving schedule displayed on the setting screen is set by the user who operates the terminal device 34 by operating a pointing device or the like, and is held in the management device 18 .

For example, the driving schedule shown in FIG. 5 can be set for each day of the week. The driving schedule set on the setting screen is transmitted from the management device 18 to the control device 10, for example, each time the setting is changed. Note that the control device 10 may acquire the driving schedule set on the setting screen from the management device 18 at a predetermined frequency (for example, 10 minutes). The control device 10 writes and holds the parameters of each item of the driving schedule received from the management device 18 in the RAM 103 or the like shown in FIG. In the setting screen shown in FIG. 5, changeable setting items are examples of change specifications.

Setting items for controlling the lighting 22 include the time when the lighting 22 is turned on, the time when the lighting 22 is turned off, power on/off, toning such as incandescent color and natural white, dimming rate, presence/absence of interlocking with motion detection, and external lighting. There is presence or absence of light correction interlocking. The power supply, motion detection interlock, and external light correction interlock indicate an enabled state when the setting switch indicated by the white circle on the screen is positioned on the right side, and indicate an disabled state when the setting switch is positioned on the left side.

When the motion interlocking is set to the valid state, the lighting retention time, the absence lighting retention time, the absence dimming rate 1, and the absent dimming rate 2 can be set. The lighting retention time, the unattended lighting retention time, the unattended dimming rate 1, and the unattended dimming rate will be described with reference to FIG.

In FIG. 5, the turn-on time of the illumination 22 is set to 8:00, the turn-off time of the illumination 22 is set to 21:00, and the power supply is set to the valid state. The toning color is set to incandescent color 2, and the dimming rate is set to 80%. The motion interlocking is set to be effective, the lighting retention time is set to 30 minutes, and the lighting retention time during absence is set to 20 minutes. The unattended dimming rate 1 is set to 30%, and the unattended dimming rate 2 is set to 0%. External light correction interlocking is set to an invalid state. The lower limit dimming rate that becomes effective when the external light correction interlock is set to the effective state is set to 10%.

When the external light correction interlock is set to the enabled state, the lower limit dimming rate can be set. The lower limit dimming rate indicates the lower limit of the dimming rate when the luminous intensity of the illumination 22 is lowered by the external light correction control. For example, when the lower limit dimming rate is set to 10%, the dimming rate is set to 10% even when the dimming rate of the lighting 22 is calculated to be 0% (that is, turned off) by the external light correction control. be.

When the external light correction interlock is set to the enabled state, the control device 10 disables the light control rate (for example, 80%) set in the driving schedule, and adjusts the light control rate according to the illuminance detected by the illuminance sensor 12. to control. For example, the illuminance sensor 12 detects the combined illuminance of light emitted from the illumination 22 and light emitted from sources other than the illumination 22 (for example, sunlight). Then, the control device 10 calculates the dimming rate using the formula (1) and sets the calculated dimming rate to the illumination 22 .
Dimming rate (%) = (max-illuminance) / (max-min) * 100 (1)
In the formula (1), the symbol max is the upper limit value (eg, 300 lux) of the illuminance when the external light correction is interlocked, and the symbol min is the lower limit value (eg, 50 lux) of the illuminance when the external light correction is interlocked. Yes, and the symbol * indicates the product. According to formula (1), the dimming rate instructed to the lighting 22 decreases as the illuminance increases, and increases as the illuminance decreases.

Note that when the illuminance is equal to or higher than the upper limit value max, the dimming rate is set to 0% regardless of Equation (1). Also, when the illuminance is equal to or lower than the lower limit value min, the dimming rate is set to 100% regardless of Equation (1). In the external light correction interlock, the control device 10 acquires the illuminance (instantaneous value) from the illuminance sensor 12 every minute, for example, and calculates the dimming rate based on Equation (1). Further, the control device 10 sets the rate of change of the dimming rate to a rate at which the lighting 22 is changed from the dimming rate of 0% to the dimming rate of 100% in 30 seconds. For example, when the amount of change in the dimming rate is 10%, the control device 10 changes the dimming rate over 3 seconds.

In addition, the motion detection interlock and the external light correction interlock can be mutually exclusive. When set to the enabled state, motion interlocking cannot be set to the enabled state.

FIG. 6 is an explanatory diagram showing an example of control of the lighting 22 when the motion detection interlocking is set to the enabled state in the lighting operation schedule of FIG. In the control shown in FIG. 6, when the absence of a person in the living room 300 is detected, for example, the second control unit 202 in FIG. This is implemented by outputting an instruction to decrease the amount of decrease in the luminosity. When the presence of a person in the living room 300 is detected, the second control unit 202 outputs information indicating the detection of the person to the first control unit 201, and the first control unit 201 controls the lighting 22 according to the operation schedule. dimming ratio.

In the initial state of FIG. 6, based on the detection information from the human sensor 14, the control device 10 continues to detect the absence of people in the room 300 (detects the absence of people), and adjusts the brightness of the lighting 22. It is set to 2 (for example, 0%: off) when not in use.

When the control device 10 detects that a person is present (detects the presence of a person), the brightness of the lighting 22 is adjusted to the dimming rate (for example, 80%) set in the operation schedule over a predetermined period of time. set. In the motion-sensitive interlocking mode, the control device 10 can set the change speed of the dimming rate to change in five steps up to the specified dimming rate for the lighting 22 . There are 5 stages of change speed: instant, 2 seconds, 8 seconds, 30 seconds, and 2 minutes.

The control device 10 does not detect the absence of a person until the lighting holding time (for example, 30 minutes) elapses after detecting the presence of a person even if it detects the absence of a person (absence). After the lighting holding time elapses, when the controller 10 detects the absence of a person, it takes a predetermined time to set the brightness of the lighting 22 to the absent dimming rate 1 set in the operation schedule. Furthermore, after setting the brightness of the lighting 22 to the dimming rate for non-attendance 1, if the non-attendance lighting retention time (for example, 20 minutes) elapses without detecting a person, the control device 10 sets the brightness for a predetermined time. By multiplying, the brightness of the lighting 22 is set to the absent dimming rate 2 set in the operation schedule. For example, the unattended dimming rate 1 is 30% and the unattended dimming rate 2 is 0%.

FIG. 7 is an explanatory diagram showing an example of a screen for setting the operation schedule of the air conditioner 24. As shown in FIG. The setting screen shown in FIG. 7 is managed by the management device 18 and displayed on the display of the terminal device 34 by cloud computing, similarly to the description of FIG. Each item displayed on the setting screen is set by the user or the like who operates the terminal device 34 . The driving schedule set on the setting screen is transmitted from the management device 18 to the control device 10, for example, each time the setting is changed. The driving schedule shown in FIG. 7 can be set for each day of the week. In the setting screen shown in FIG. 7, changeable setting items are examples of change specifications.

Setting items for controlling the air conditioner 24 include operation start time (reservation time), operation stop time, power on/off, temperature (set temperature), operation mode, air volume, air direction, option selection, and the like. be. Similar to FIG. 5, the power supply indicates an active state when the setting switch indicated by the white circle on the screen is positioned to the right. The operation modes include automatic, heating, cooling, dehumidifying, blowing, etc. In the case of automatic, either heating or cooling is selected according to the outside temperature.

As an option, it is possible to select one of the motion-sensitive mode, energy-saving priority mode, and comfort-priority mode. The motion interlocking mode uses the motion sensor 14 to detect whether or not there is a person in the room 300, and if there is no person, the set temperature is lowered (for example, 2°C) during heating, and the set temperature is decreased during cooling. In this mode, the power consumption is reduced by increasing the temperature (for example, 2° C.). Hereinafter, the energy-saving priority mode and the comfort-priority mode are also referred to as temperature-linked modes. Although not shown in FIG. 7, when the motion interlocking mode is selected, an input field for setting the amount of change in the set temperature when the absence of a person is detected appears on the setting screen, as will be described with reference to FIG. Is displayed.

Energy-saving priority mode, for example, in the case of heating, if the set temperature is higher than the room temperature, control is performed to lower the room temperature to the set temperature, and if the set temperature is lower than the room temperature, control is not performed, thereby reducing power consumption. It is a mode to suppress. In cooling in the energy-saving priority mode, when the set temperature is lower than the room temperature, control is performed to raise the room temperature to the set temperature, and when the set temperature is higher than the room temperature, control is not performed.

Comfort priority mode, for example, in the case of heating, if the set temperature is higher than the room temperature, control is performed to lower the room temperature to the set temperature, and if the set temperature is lower than the room temperature, control is performed to raise the room temperature to the set temperature. It is a mode that maintains comfort. In cooling in the comfort priority mode, control is performed to raise the room temperature to the set temperature when the set temperature is lower than the room temperature, and control is performed to lower the room temperature to the set temperature when the set temperature is higher than the room temperature.

In FIG. 7, the start time of operation is set to 8:00, the stop time of operation is set to 21:00, the power is set to enabled, and the option is not selected. In this case, the control device 10 starts operation at the start time, controls the air conditioner 24 according to the temperature, operation mode, air volume, and wind direction set in the operation schedule, and stops operation at the stop time.

However, when the power supply is set to the disabled state, the start time, stop time and preliminary operation are disabled, and the control device 10 does not control the operation of the air conditioner 24 . In this case, the operation of the air conditioner 24 is started by operating the air conditioning controller 26, and the temperature, operation mode, air volume, and air direction are set, or the operation is stopped. Note that the control device 10 may start the preliminary operation before the start time so that the room temperature reaches the set temperature at the start time.

For example, settings made by the air conditioning controller 26 take precedence over settings made by the operating schedule. Therefore, even if the power supply is set to the valid state on the operation schedule setting screen and the operation of the air conditioner 24 is stopped before the start time or after the stop time, the air conditioner controller 26 is turned on, the air conditioner 24 starts operating. Similarly, even when the power supply is set to the enabled state on the operation schedule setting screen and the air conditioner 24 is operating between the start time and the stop time, the air conditioner controller 26 controls the air conditioner 24 is turned off, the air conditioner 24 stops operating.

Further, if one or more of the settings of the temperature, operation mode, air volume, and wind direction are changed by the air conditioning controller 26 during the operation of the air conditioner 24, the operation of the air conditioning controller 26 may be changed from the setting of the operation schedule. also takes precedence. However, when the power supply is set to the valid state on the operation schedule setting screen, even if the air conditioner 24 is turned off by the air conditioning controller 26, the operation of the air conditioner 24 is started based on the start time of the operation schedule. be.

FIG. 8 is an explanatory diagram showing an example of a setting screen for demand control that is performed according to the alarm level when the controller 10 detects an alarm. The setting screen shown in FIG. 8 is managed by the management device 18 and displayed on the display of the terminal device 34 by cloud computing, similarly to the description of FIG. Each item displayed on the setting screen is set by the user or the like who operates the terminal device 34, and the items set on the setting screen are changed, for example, every time the setting is changed or when the management device 18 sets the alarm level. Each time it is received, it is transmitted from the management device 18 to the control device 10 . The setting screen shown in FIG. 8 exists for each alarm level, and FIG. 8 shows the setting screen for alarm level 1. FIG. In the setting screen shown in FIG. 8, changeable setting items are examples of change specifications.

Setting items for demand control include target power, lower limit dimming rate, lighting dimming fluctuation value, air conditioning power on/off, air conditioning operation mode, set temperature (change amount) during heating, and Set temperature (change amount), etc. A lower limit dimming rate indicating the lower limit of the dimming rate can be set between 0% and 100%, and is commonly set for a plurality of alarm levels. The dimming variation value can be set between 0% and -100%. Here, -0% of the dimming fluctuation value indicates that the dimming rate is not changed, and -100% of the dimming fluctuation rate indicates that the illumination 22 is turned off.

Similar to FIG. 5, the power supply indicates an active state when the setting switch indicated by the white circle on the screen is positioned to the right. When the power supply is set to the enabled state, the run mode is enabled. When the power supply is set to the disabled state, the operation mode is disabled for each alarm level, and the air conditioner 24 is powered off when the controller 10 detects the alarm.

Operation modes include a set temperature change mode and a fan mode (not shown). When the set temperature change mode is selected, the set temperature for heating and the set temperature for cooling are valid. The set temperature during heating indicates the amount of reduction from the set temperature set when demand control is not performed, and can be set between 0°C and -10°C, for example. The set temperature during cooling indicates an increase range with respect to the set temperature set when the demand control is not performed, and can be set between 0°C and 10°C, for example. When the operation mode is the air blowing mode, the air conditioner 24 is in the air blowing state during demand control.

FIG. 9 is an explanatory diagram showing an example of control of the lighting 22 by the control device 10 of FIG. When the control device 10 does not perform demand control, that is, when it does not detect an alarm generated by the power monitoring device 30, it performs only normal automatic control under the control of the first control unit 201 in FIG. When detecting an alarm, the control device 10 performs demand control in addition to automatic control according to a second instruction output from the third control section 203 to the first control section 201 .

In the automatic control mode in which automatic control is performed, when both the motion detection interlocking and the external light correction interlocking are disabled, the setting items other than the human detection interlocking and the external light correction interlocking in the driving schedule shown in FIG. Control of lighting 22 is performed according to standard items. The first control unit 201 performs automatic control when both the motion detection interlocking and the external light correction interlocking are disabled. For example, in the operation schedule shown in FIG. 5, from 8:00 to 21:00 on a certain day, the lighting 22 is tuned to incandescent color 2 and is lit with a dimming rate of 80%.

When the motion interlocking is in the enabled state, in addition to the control of the lighting 22 according to the standard items, the first instruction output from the second control unit 202 to the first control unit 201 causes human motion as shown in FIG. Control of the dimming rate is performed according to presence/absence. When the external light correction interlock is enabled, the third instruction output from the second control unit 202 to the first control unit 201 causes the illuminance detected by the illuminance sensor 12 to control the dimming rate.

On the other hand, in demand control, the second instruction output from the third control unit 203 to the first control unit 201 subtracts the light control fluctuation value corresponding to the alarm level from the light control rate set by automatic control. However, if the light control rate after the reduction is equal to or lower than the lower limit value of the light control rate, the light control rate is set to the lower limit value. The higher the number of the warning level, the greater the excess of the predicted power consumption over the target power consumption, and the higher the urgency.

FIG. 10 is an explanatory diagram showing an example of control of the air conditioner 24 by the control device 10 of FIG. When the control device 10 does not perform demand control, that is, when it does not detect an alarm generated by the power monitoring device 30, it performs only normal automatic control under the control of the first control unit 201 in FIG. When detecting an alarm, the control device 10 performs demand control in addition to automatic control according to a second instruction output from the third control section 203 to the first control section 201 .

When the motion interlocking is enabled, the first instruction output from the second control unit 202 to the first control unit 201 lowers the set temperature, for example, by 2° C. from the set temperature of the standard item during the heating operation, and the cooling operation is performed. Sometimes the set temperature is raised, for example, by 2° C. over the set temperature of the standard item. When temperature interlocking (energy-saving priority mode or comfort priority mode) is enabled, the sixth instruction output from the second control unit 202 to the first control unit 201 changes the temperature according to each mode as described above. Control is enforced.

On the other hand, in the demand control, the set temperature is adjusted by the second instruction output from the third control section 203 to the first control section 201 . For example, as shown in FIG. 8, when the power is turned on on the setting screen and the operation mode is set to change the set temperature, the control device 10 automatically changes the set temperature fluctuation value according to the alarm level. Add to the set temperature set in control mode. In the example shown in FIG. 8, during cooling, the set temperature is raised by 1° C. regardless of the alarm level, and during heating, the set temperature is lowered by 1° C. as the alarm level rises.
