Description

  The present invention relates to a device control device that controls the state of a load device such as a lighting device.

2. Description of the Related Art Conventionally, a system that controls equipment by remote operation input is known. For example, Patent Document 1 discloses a system that controls equipment by operating input from a daylight switch. The daylight switch detects ambient illuminance at the light receiving unit, and outputs operation data according to the magnitude of the output of the light receiving unit and the threshold value at the data generating unit. Specifically, the data generation unit generates operation data for turning on the illumination load when the ambient illuminance is smaller than the dark level threshold, and reduces the illumination load when the ambient illuminance exceeds the bright level threshold brighter than the dark level threshold. Generate operation data to turn off. The delay circuit unit delays the operation data and inputs it to the signal processing unit through the output circuit unit. The signal processing unit transmits operation data to the transmission control device by a time division multiplex transmission method. When the transmission control device separated from the daylight switch receives the operation data, the transmission control device sends the control data to the control terminal having the lighting load to control the lighting load. As described above, the daylight switch itself has a function as a brightness sensor that detects the ambient illuminance, and is disposed in the detection area to detect the brightness.
Japanese Patent Laid-Open No. 08-154280

  However, according to the technique disclosed in Patent Document 1, the state control of the lighting device is performed at a timing different from a desired time due to the installation location of the brightness sensor which is a daylight switch. there is a possibility. For example, if the daylight switch is installed in an environment that tends to be shaded, the lighting device is turned on at an earlier timing than the surrounding brightness, or the daylight switch When it is installed in an environment that is easily affected, the lighting device is turned on at a later timing than the surrounding brightness.

  Although this daylight switch has a function to delay operation data and the sensitivity to brightness can be adjusted, the daylight switch etc. is arranged at a high place to detect the brightness around the lighting device. In many cases, the adjustment cannot be easily performed.

  The present invention has been made in view of such circumstances, and an object of the present invention is to perform the control of the lighting device in accordance with the surrounding brightness environment at a flexible timing and the control timing thereof. Is easy to adjust.

  In order to solve this problem, the present invention provides a device control apparatus. This device control device is a sensor connected to a relay connection unit connected to a relay that switches the lighting device state on or off according to its own open / closed state, and a brightness sensor that detects the brightness around the lighting device. Brightness determination that determines the brightness around the lighting device as a bright state or a dark state based on a preset brightness reference value based on the output from the brightness sensor input to the connection portion and the sensor connection portion A relay control unit that outputs a control signal for controlling the state of the relay to the relay via a relay connection unit, and a time setting unit that sets a set time that is a parameter that can be adjusted by an administrator by operating a switch. The set time set in the time setting unit based on the brightness change timing at which the determination result in the brightness determination unit changes between the bright state and the dark state In only it is offset timing, and a control processing unit for instructing the output of the control signal to the relay control unit.

  Here, in the present invention, the control processing unit instructs the relay control unit to output a control signal at a timing delayed by a set time set by the time setting unit on the basis of the brightness change timing. It is preferable.

  Further, in the present invention, the device control apparatus stores the time corresponding to the brightness change timing as time data, and the average brightness change timing based on the time data stored in the storage section. It is preferable to further include an average calculation unit that calculates a correct time as an average time. In this case, the control processing unit predicts that the next brightness change timing is the average time calculated by the average calculation unit, and precedes the set time set by the setting unit based on the average time. At this timing, the relay control unit is instructed to output a control signal.

  In the present invention, it is preferable that the average calculation unit corrects the average time based on a reference time indicating a brightness change standard corresponding to the regional characteristics and the date characteristics.

  In the present invention, the brightness change includes a first brightness change from a bright state to a dark state, and the control processing unit switches the lighting device to a lighting state in response to the first brightness change. It is preferable to instruct the relay control unit to output a control signal so as to control.

  Furthermore, in the present invention, the brightness change includes a second brightness change from the dark state to the bright state, and the control processing unit controls the lighting device to the extinguished state in response to the second brightness change. Thus, it is desirable to instruct the relay control unit to output a control signal.

  According to the present invention, the state control of the lighting device is performed by offsetting the timing by the set time rather than the timing of the brightness change determined based on the output of the brightness sensor. When the state control of the lighting device is performed according to the timing of the brightness change, the state of the lighting device is controlled before or after the desired time due to the installation position of the brightness sensor, etc. In some cases, the lighting device can be turned on or off in accordance with the adjustment of the set time.

  According to the present invention, the device control device and the brightness sensor are independent of each other. The equipment control device is placed in a position that can be maintained by the administrator in consideration of normal maintenance, etc., so even if the brightness sensor is placed in a poorly maintainable place such as a high place Time can be adjusted easily. Thereby, when controlling an illuminating device according to the surrounding brightness environment, it can be performed at a flexible timing and the control timing can be easily adjusted.

  Further, according to the present invention, the state control of the lighting device is performed by delaying the timing by the set time rather than the timing of the brightness change. Thereby, the inconvenience that the lighting device is turned on / off at a timing earlier than the desired time can be suppressed.

  In addition, according to the present invention, the average time that is the timing of the brightness change is predicted, and the state control of the lighting device is performed with the timing preceding the average time by the set time. Thereby, the inconvenience that the lighting device is turned on / off at a timing later than the desired time can be suppressed.

  In addition, according to the present invention, it is possible to suppress the deterioration of the calculation accuracy of the average time, and therefore it is possible to optimize the timing of the state control of the lighting device.

  FIG. 3 is a block diagram showing the configuration of the scheduled time control unit 1. The scheduled time control unit 1 is mainly configured by a microcomputer (control processing unit) 10, and various circuits are connected to the microcomputer 10.

  The mode switch input circuit 11 is connected to the mode switch 1c and detects an operation of the mode switch 1c. The change operation of the mode change switch 1c detected by the mode change switch input circuit 11 is detected by the microcomputer 10, whereby the microcomputer 10 determines whether the current mode is the normal mode or the setting mode (more specifically, Is recognized as current time setting, lighting time setting or extinguishing time setting).

  The operation changeover switch input circuit 12 is connected to the operation changeover switch 1f and detects an operation of the operation changeover switch 1f.

Is recognized.

  The hour selector switch input circuit 13 is connected to the hour selector switch 1d and detects an operation of the hour selector switch 1d.

Is done.

  The minute changeover switch input circuit 14 is connected to the minute changeover switch 1e and detects the operation of the minute changeover switch 1e.

Is done.

  The time setting volume input circuit 15 is connected to the time setting volume 1g and detects an operation of the time setting volume 1g. The switching operation of the minute / hour setting volume 1g detected by the time setting volume input circuit 15 is detected by the microcomputer 10, and thereby the setting of the setting time is changed by the microcomputer 10.

  The EEPROM 16 stores various setting data for operating the microcomputer 10. Examples of setting data stored in the EEPROM 16 include IDs of a plurality of lighting devices to be controlled, flags indicating the current mode, and the like. In addition to this, when the lighting time in the lighting time setting and the lighting time in the lighting time setting are set, these times are stored as setting data, and when the setting time is set Is stored as setting data.

  The reset circuit 17 is provided for performing a setting operation for returning the setting data stored in the EEPROM 16 to an initial value. The reset circuit 17 is connected to a reset operation unit (not shown), and resets the content of setting data stored in the EEPROM 16 by the microcomputer 10 to an initial value in accordance with the operation of the reset operation unit.

  The oscillation circuit 18 measures the elapsed time in the operation mode in the normal mode. The oscillation circuit 18 starts measuring time according to the control of the microcomputer 10, and the measured value is read by the microcomputer 10.

  The clock oscillation circuit 19 is an oscillation circuit for a clock function in the on-time control unit 1. The clock oscillation circuit 19 is read by the microcomputer 10 in order to perform an operation of turning on or off the lighting device at a predetermined time (lighting time) by the on-time control unit 1. For example, when “09: 0” is set as the lighting time and “18:00” is set as the light-off control in the setting data of the EEPROM 16, the microcomputer 10 sets the light-on time, the light-off time and the clock oscillation circuit 19. The clock time is compared.

  The liquid crystal display unit 20 displays various information on the liquid crystal display screen 1b. When the setting data stored in the EEPROM 16 is changed or when the clock time is changed, the setting change contents are displayed on the liquid crystal display unit 20.

  The bridge circuit 21 is connected to an AC 100V commercial power supply via the output terminal 1 j, and full-wave rectified and supplied to the power supply circuit 22.

  The power supply circuit 22 generates low-voltage power for the microcomputer 10 and power to other circuits constituting the on-time control unit 1 from the power supplied via the bridge circuit 21.

  The power supply voltage detection circuit 23 detects the power supply voltage value supplied from the commercial power supply to the power supply circuit 22 via the output terminal 1 j and the bridge circuit 21, and supplies it to the microcomputer 10. The power supply voltage detection circuit 23 is detected by the microcomputer 10 when the signal from the power supply circuit 22 is not supplied due to a power failure or the like. In response to this, the microcomputer 10 enters a wait mode for reducing power consumption and backs up the current time measured by the clock oscillation circuit 19 in the EEPROM 16.

  The backup power supply circuit 24 is composed of, for example, an internal capacitor. When the power supply circuit 22 cannot supply power to the microcomputer 10 and other circuits during a power failure, the microcomputer 10 supplies power for backing up the current time and the like. The power supplied from the backup power supply circuit 24 to the microcomputer 10 at the time of a power failure is set to a low power supply voltage in order to reduce the power consumption compared to the normal time.

  The brightness sensor detection circuit 25 detects an output from the brightness sensor 2 input via the brightness sensor terminal 1i. When the surroundings of the brightness sensor 2 are bright, the brightness sensor detection circuit 25 can detect the commercial power supply from the brightness sensor 2, and when the surroundings of the brightness sensor 2 is not bright (when dark), the brightness is detected. The sensor detection circuit 25 cannot detect the commercial power supply from the brightness sensor 2. Thereby, the microcomputer 10 determines whether the periphery of the illumination device is bright or dark depending on the presence / absence of a signal from the brightness sensor 2 to the brightness sensor detection circuit 25. In other words, the brightness sensor detection circuit 25 is based on the output from the brightness sensor 2 input to the brightness sensor terminal 1i, and the brightness around the lighting device with a preset brightness reference value as a boundary. Is determined as a bright state or a dark state (brightness determination unit).

  The one-pulse output circuit 26 includes a built-in relay, and generates a current pulse for operating the built-in relay according to the output of an instruction signal (on control or off control) from the microcomputer 10. The built-in relay is switched from the off state to the on state in response to a current pulse for on control. In response to a control signal corresponding to the change of the built-in relay, the remote control relay 5 is switched from the off state to the on state. On the other hand, the built-in relay is switched from the on state to the off state in response to the current pulse for off control. In response to the control signal corresponding to the relay change, the remote control relay 5 is switched from the on state to the off state. Thereby, the microcomputer 10 can control the lighting state or the extinguishing state of the lighting device. In other words, the one-pulse output circuit 26 functions as a relay control unit that outputs a control signal for controlling the state of the relay to the remote control relay 5 through the output terminal 1j.

  The microcomputer 10 controls the one-pulse output circuit 26 so as to control the state of the lighting device in accordance with the timing of the brightness change in which the determination result in the brightness sensor detection circuit 25 changes between the bright state and the dark state. An instruction signal is output to Specifically, the brightness change includes a first brightness change from a bright state to a dark state, and the microcomputer 10 controls the lighting device to a lighting state in response to the first brightness change. In this manner, the one-pulse output circuit 26 is instructed to output an instruction signal (ON signal). Further, the brightness change includes a second brightness change from the dark state to the bright state, and the microcomputer 10 controls the lighting device to the extinguished state in response to the second brightness change. It instructs the one-pulse output circuit 26 to output a control signal (off control).

  Here, as one of the features of the present embodiment, the microcomputer 10 performs one pulse at a timing offset by a set time recognized through the time setting volume input circuit 15 with the timing of the first brightness change as a reference. The output circuit 26 is instructed to output a control signal (brightness offset control). In this case, when the plus time is set as the set time, the microcomputer 10 controls the state of the lighting device at a timing delayed by the set set time with reference to the brightness change timing. . On the other hand, when “0” is set as the set time by the time setting volume 1g, the microcomputer 10 controls the state of the illumination device at the brightness change determination timing. On the other hand, when the minus time is set as the set time by the time setting volume 1g, the microcomputer 10 makes the timing preceded by the set time based on the brightness change determination timing. In, the state of the lighting device is controlled.

  Further, when the remote control switch 6 is operated, the on-time control unit 1 outputs a control signal of the remote control switch 6 to an output terminal 1j that is an output terminal to the remote control relay 5 connected internally. With this configuration, the on-time control unit 1 realizes a control for turning on or off the lighting device according to time or brightness, and an operation for turning on or off the lighting device by operating the remote control switch 6.

  FIG. 4 is a flowchart showing state control of the illumination device according to the first embodiment of the present invention. The processing shown in this flowchart is executed by the microcomputer 10 of the scheduled time control unit 1. In this embodiment, the mode changeover switch 1c is set to the normal mode, and the time setting volume 1g is within the range of the set time from “0” to “+ b” (plus the time on the plus side including 0). It is executed on the assumption that it is set to (within range).

  First, in step 10 (S10), it is determined whether or not the state of the operation switch 1f is the operation mode. If an affirmative determination is made in step 10, that is, if the operation mode is set, the process proceeds to step 11 (S11). On the other hand, when a negative determination is made in step 10, that is, when the operation mode is not set (when the operation mode is the stop mode), the process to be described later is skipped and the routine is exited.

  In step 11, it is determined whether or not there is time control. Specifically, when a lighting time or a light-off time is set and the time corresponds to the time measured by the clock oscillation circuit 19, an affirmative determination is made in step 11, and step 17 (S17 described later) is performed. ). On the other hand, if the lighting time or the lighting time is not set, or the lighting time or the lighting time is set, but the time does not correspond to the time measured by the clock oscillation circuit 19, a negative result is obtained in step 11. Determination is made, and the process proceeds to step 12 (S12).

  In step 12, it is determined whether or not there has been a change in brightness. Specifically, when the brightness around the lighting device changes from the bright state to the dark state (first brightness change), or the brightness around the lighting device changes from the dark state to the bright state. If it has changed (second brightness change), an affirmative determination is made in step 12, and control proceeds to step 13 (S13). On the other hand, if there is no change in brightness, a negative determination is made in step 12 and the routine is exited.

  In step 13 (S13), it is determined whether or not the lighting device is on-controlled, that is, whether or not the brightness change is the first brightness change. If an affirmative determination is made in step 13, that is, if the brightness change is the first brightness change, the process proceeds to step 14 (S14). On the other hand, if a negative determination is made in step 13, that is, if the brightness change is not the first brightness change, the process proceeds to step 16 (S16).

  In step 14, a standby process is performed to wait for a set time set by the time setting volume 1g. In this standby process, the elapsed time by the oscillation circuit 18 is referred to.

  In step 15 (S15), an instruction signal for ON control is output to the one-pulse output circuit 26 (ON output). On the other hand, in step 16 (S16), an instruction signal for OFF control is output to the one-pulse output circuit 26 (OFF output).

  In step 17, it is determined whether or not the lighting device is on-controlled. Specifically, when the time corresponding to the time measured by the clock oscillation circuit 19 is the lighting time, an affirmative determination is made in step 17 and the process proceeds to step 18 (S18). On the other hand, if the time corresponding to the time measured by the clock oscillation circuit 19 is not the lighting time, that is, the turn-off time, a negative determination is made in step 18, and the process proceeds to step 19 (S19).

  In step 18, a control signal that is ON control is output to the one-pulse output circuit 26 (ON output). On the other hand, in step 19 (S19), a control signal for off control is output to the one-pulse output circuit 26 (off output).

  FIG. 5 is an explanatory diagram showing the flow of processing shown in the first embodiment in time series. As shown in the figure, when a brightness change from the bright state to the dark state (first brightness change) is detected via the brightness sensor detection circuit 25 that acquires the output from the brightness sensor 2. The microcomputer 10 outputs an ON control instruction signal to the one-pulse output circuit 26 at a timing delayed by a set time B from the brightness change timing. Accordingly, a current pulse for ON control is generated in the one-pulse output circuit 26, and in response to this (specifically, in response to the fall of the voltage), the built-in relay changes from the OFF state to the ON state. It can be switched. In response to the relay change of the built-in relay, when the remote control relay 5 is switched to the on state, the lighting device is controlled to be in the lighting state.

  When the brightness change from the dark state to the bright state (second brightness change) is detected via the brightness sensor detection circuit 25 that acquires the sensor signal from the brightness sensor 2, the microcomputer 10. Outputs an instruction signal corresponding to OFF control to the one-pulse output circuit 26 at the timing of this brightness change. Accordingly, a current pulse for off control is generated in the one-pulse output circuit 26. Correspondingly (specifically, in response to the fall of the voltage), the built-in relay changes from the on state to the off state. It can be switched. When the remote control relay 5 is switched to the off state in response to the relay change of the built-in relay, the lighting device is controlled to be turned off.

  As described above, according to the present embodiment, the brightness offset control delays the timing by the set time from the timing of the first brightness change determined based on the output of the brightness sensor 2 by the brightness offset control. State control is performed. When the state control of the lighting device is performed according to the timing of the brightness change, there arises a disadvantage that the lighting device is turned on earlier than a desired time due to the installation position of the brightness sensor 2 or the like. However, according to the present embodiment, the lighting time of the lighting device can be optimized according to the adjustment of the set time. As a result, a remote control system that is easy for the user to use can be provided.

  Moreover, the scheduled time control unit 1 and the brightness sensor 2 are independent of each other. The scheduled time control unit 1 is arranged at a position where the administrator can maintain it in consideration of normal maintenance, etc., so that the brightness sensor 2 is arranged at a place with poor maintainability such as a high place. Also, the set time can be easily adjusted. Thereby, when controlling an illuminating device according to the surrounding brightness environment, it can be performed at a flexible timing, and the control timing can be easily adjusted.

(Second Embodiment)
The remote control system in the second embodiment is different from that in the first embodiment in that the state of the lighting device is turned on in advance by a set time with reference to the timing of the first brightness change. . The system configuration of the on-time control unit 1 is the same as that of the first embodiment, and the following description will focus on the differences.

  FIG. 6 is a flowchart showing state control of the illumination device according to the second embodiment of the present invention. The processing shown in this flowchart is called at a predetermined cycle and executed by the microcomputer 10 of the on-time control unit 1. In the process shown in the figure, the mode changeover switch 1c is set to the normal mode, and the time setting volume 1g sets the set time within the range of values smaller than “−a” to “0”. It is executed on the assumption that

  First, in step 20 (S20), it is determined whether or not the state of the operation changeover switch 1f is the operation mode, similarly to the processing of step 10 shown in the first embodiment. If an affirmative determination is made in step 20, the process proceeds to step 21 (S21). On the other hand, if a negative determination is made in step 20, the process to be described later is skipped and the routine is exited.

  In step 21, it is determined whether or not there is time control, similar to the processing in step 11 shown in the first embodiment. If an affirmative determination is made in step 21, the process proceeds to step 29 (S29) described later. On the other hand, if a negative determination is made in step 21, the process proceeds to step 22 (S22).

  In step 22, it is determined whether or not the time measured by the clock oscillation circuit 19 corresponds to a time preceding the reference time A by a set time B (reference time A−set time B (absolute value)). Here, the reference time A is an average time calculated in step 26 (S26) described later, and is stored in the EEPROM 16 as setting data. The microcomputer 10 can obtain the average time A by referring to the EEPROM 16. If an affirmative determination is made in step 22, the process proceeds to step 23 (S23). On the other hand, if a negative determination is made in step 22, the process proceeds to step 28 (S28).

  In step 23, it is determined whether or not there has been a change in brightness, as in the process of step 11 shown in the first embodiment. If the first brightness change or the second brightness change has occurred, an affirmative determination is made in step 23, and the process proceeds to step 24 (S24). On the other hand, if there is no change in brightness, a negative determination is made in step 23 and the routine is exited.

  In step 24 (S24), it is determined whether or not the lighting device is on-controlled, that is, whether or not the brightness change is the first brightness change. If an affirmative determination is made in step 24, that is, if the brightness change is the first brightness change, the process proceeds to step 25 (S25). On the other hand, when a negative determination is made in step 24, that is, when the brightness change is not the first brightness change (when the brightness change is the second brightness change), step 27 (S27). Proceed to

  In step 25, the time corresponding to the first brightness change is stored in the EEPROM 16 as time data.

  In step 26 (S26), the time data stored in the EEPROM 16 and the history of the time corresponding to the past first brightness change are referred to, and the average time is calculated. The calculated average time is updated as data in the EEPROM 16 as a new reference time A.

  In step 27 (S27), an instruction signal for OFF control is output to the one-pulse output circuit 26 (OFF output).

  In step 28, an instruction signal for ON control is output to the one-pulse output circuit 26 (ON output).

  On the other hand, in step 29, it is determined whether or not the lighting device is on-controlled. Specifically, when the time corresponding to the time measured by the clock oscillation circuit 19 is the lighting time, an affirmative determination is made in step 29 and the process proceeds to step 30 (S30). On the other hand, when the time corresponding to the time measured by the clock oscillation circuit 19 is not the lighting time, that is, the light-off time, a negative determination is made in step 29 and the process proceeds to step 31 (S31).

  In step 30, an instruction signal for ON control is output to the one-pulse output circuit 26 (ON output). On the other hand, in step 31 (S31), an instruction signal for OFF control is output to the one-pulse output circuit 26 (OFF output).

  FIG. 7 is an explanatory diagram showing the flow of processing shown in the second embodiment in time series. As shown in the figure, the brightness change from the bright state to the dark state (first brightness change) is not detected via the brightness sensor detection circuit 25 that acquires the sensor signal from the brightness sensor 2. In any case, the microcomputer 10 outputs an ON control instruction signal to the one-pulse output circuit 26 at a timing preceding the reference time A by the set time B. Accordingly, a current pulse for ON control is generated in the one-pulse output circuit 26, and in response to this (specifically, in response to the fall of the voltage), the built-in relay changes from the OFF state to the ON state. It can be switched. In response to the relay change of the built-in relay, when the remote control relay 5 is switched to the on state, the lighting device is controlled to be in the lighting state.

  When the brightness change from the dark state to the bright state (first brightness change) is detected via the brightness sensor detection circuit 25 that acquires the sensor signal from the brightness sensor 2, the microcomputer 10. Outputs a signal signal corresponding to the OFF control to the one-pulse output circuit 26 at the timing of the brightness change. Accordingly, a current pulse for off control is generated in the one-pulse output circuit 26. Correspondingly (specifically, in response to the fall of the voltage), the built-in relay changes from the on state to the off state. It can be switched. When the remote control relay 5 is switched to the off state in response to the relay change of the built-in relay, the lighting device is controlled to be turned off.

  As described above, according to the present embodiment, the timing of the first brightness change determined based on the output of the brightness sensor 2 by the brightness offset control, specifically, the reference time (statistics based on past data). The state control of the lighting device is performed with the timing preceded by the set time (average time of first brightness change calculated automatically). When the state control of the lighting device is performed according to the timing of the brightness change, there may be a problem that the lighting device is turned on later than the desired time due to the installation position of the brightness sensor 2 or the like. However, according to this embodiment, the lighting time of the lighting device can be optimized according to the adjustment of the set time. As a result, a remote control system that is easy for the user to use can be provided.

  In addition, the timing of the first brightness change that occurs next time is predicted to be the average time, and the state control of the lighting device is performed at a timing that is preceded by the set time based on the average time. Thereby, even if the first brightness change does not actually occur, the control timing of the illumination device can be performed in advance.

(Third embodiment)
The remote control system in the third embodiment is different from that in the second embodiment in that the average time set in the reference time A is corrected and calculated. Note that the system configuration of the on-time control unit 1 is the same as that of the second embodiment, and the following description will focus on differences.

  In this embodiment, the scheduled time control unit 1 has the following functions, unlike the first or second embodiment.

  First, referring again to FIG. 2, when the mode changeover switch 1c is operated to switch from the normal mode to the setting mode, in addition to the current time setting, lighting time setting, and extinguishing time setting, the current date is set. The area selection which selects the number (for example, the number which designates a prefecture) applicable to the area where the lighting device is installed and the date and time to perform is possible. This mode changeover switch 1c can be operated by an administrator, and not only switching between the normal mode and the setting mode, but also the current time setting, lighting time setting, extinguishing time setting, month / day setting, region selection in the setting mode Can be switched.

  In addition to the function shown in the first embodiment, the hour selector switch 1d is an operation for switching the “month” of the month and day in the setting when the mode selector switch 1c is switched to the month / day setting in the setting mode. Functions as a switch. In this case, the hour selector switch 1d can switch “month” in the range of “1” to “12”.

  In addition to the function shown in the first embodiment, the minute selector switch 1e is an operation for switching the “day” of the month and day in the setting when the mode selector switch 1c is switched to the month and day setting in the setting mode. Functions as a switch. In this case, the hour selector switch 1d can switch “day” in the range of “1” to “31”. The minute selector switch 1e functions as an operation switch for switching the “region number” in the setting when the mode selector switch 1c is switched to the region selection in the setting mode.

  Referring again to FIG. 3, the hour changeover switch input circuit 13 is connected to the hour changeover switch 1d and detects the operation of the hour changeover switch 1d. The operation of the hour selector switch 1d detected by the hour selector switch input circuit 13 is detected by the microcomputer 10, and the microcomputer 10 changes the "month" setting in the month and day setting.

  The minute changeover switch input circuit 14 is connected to the minute changeover switch 1e and detects the operation of the minute changeover switch 1e. The operation of the minute changeover switch 1e detected by the minute changeover switch input circuit 14 is detected by the microcomputer 10, whereby the microcomputer 10 changes the setting of “day” in the month and day setting, and “ The area code setting is changed.

  The EEPROM 16 holds a map in which the date and area number and the reference time are associated with each other. This reference time is a time indicating a brightness change reference (for example, sunset time and sunrise time) reflecting the regional characteristics and the moon-day characteristics, and can be acquired in advance through experiments and simulations.

  FIG. 8 is a flowchart showing the state control of the illumination device according to the third embodiment of the present invention. The processing shown in this flowchart is called at a predetermined cycle and executed by the microcomputer 10 of the on-time control unit 1. In the process shown in the figure, the mode changeover switch 1c is set to the normal mode, and the time setting volume 1g sets the set time within a range of values smaller than “−a” to “0”. It is executed on the assumption that

  Here, in the processing shown in the figure, the processing from step 40 (S40) to step 44 (S44) corresponds to the processing from step 20 to step 24 in the second embodiment, and step 49 (S49). ) To step 53 (S53) corresponds to the processing from step 27 to step 31 in the second embodiment. Accordingly, overlapping description will be omitted, and the processing from step 45 (S45) to step 48 (S48), which are different points, will be described below.

  First, in step 45, a time corresponding to the first brightness change (hereinafter referred to as “change time”) is acquired.

  In step 46 (S46), the map stored in the EEPROM 16 is referred to based on the month and day set in the month and day setting and the region number selected in the region selection, thereby identifying the reference time. Next, when the difference between the reference time and the change time is calculated, it is determined whether or not this time difference is equal to or longer than a specified time. Here, the specified time is a time for determining that the difference between the reference time and the change time has deviated to an unacceptable range, and an optimum value thereof is set in advance. If an affirmative determination is made in step 46, that is, if the difference from the reference time is greater than or equal to the specified time, the processing of step 47 (S47) and step (S48) is skipped and the routine is exited. On the other hand, if a negative determination is made in step 46, that is, if the difference from the reference time is smaller than the specified time, the process proceeds to step 47.

  In step 47, the change time is stored in the EEPROM 16 as time data. In step 48, the time data stored in the EEPROM 16 and the history of the time corresponding to the past first brightness change are referred to, and the average time is calculated. The calculated average time is updated as a new reference time A.

  As described above, according to the present embodiment, the average time is corrected based on the reference time indicating the standard of the brightness change corresponding to the regional characteristics and the date characteristics. If the time of the first brightness change deviates significantly due to the influence of the weather or the like, the calculation accuracy of the average time is lowered, and there is a possibility that the timing of the state control of the lighting device may also deteriorate. However, according to the present embodiment, an abnormal time out of the time corresponding to the first brightness change can be excluded from the time data by comparison with the reference time. Therefore, it is possible to suppress the deterioration of the calculation accuracy of the average time, and it is also possible to suppress the deterioration of the timing control of the lighting device.

  In addition, as a correction method of average time, it is not limited to the method mentioned above, The method as shown next may be sufficient. Specifically, as in the second embodiment, the time corresponding to the first brightness change is stored in the EEPROM 16 as time data, and the average time is calculated based on this time data. When the difference between the average time and the reference time is equal to or longer than the specified time, the reference time is used as the reference time instead of the average time. In this way, the average time may be corrected by using the reference time instead.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made to the above embodiments without departing from the scope of the invention.

  For example, in the first to third embodiments described above, the brightness offset control is performed based on the first brightness change, but the brightness offset control is performed based on the second brightness change. May be. In this case, brightness offset control may be performed only for the second brightness change, or brightness offset control may be performed for both the first brightness change and the second brightness change. May be. In addition, the set time can be individually set for each of the first brightness change and the second brightness change.

  FIG. 9 is an explanatory diagram showing the processing flow of brightness offset control in time series. In the brightness offset control shown in FIG. 9, the set time corresponding to the first brightness change is set within a range of values smaller than “−a” to “0”, and corresponds to the second brightness change. It is assumed that the set time is set within the range of “0” to “b”.

  As shown in the figure, the brightness change from the bright state to the dark state (first brightness change) is not detected via the brightness sensor detection circuit 25 that acquires the sensor signal from the brightness sensor 2. In any case, the microcomputer 10 outputs an ON control instruction signal to the one-pulse output circuit 26 at a timing preceding the reference time A by the set time B. Accordingly, a current pulse for ON control is generated in the one-pulse output circuit 26, and in response to this (specifically, in response to the fall of the voltage), the built-in relay changes from the OFF state to the ON state. It can be switched. In response to the relay change of the built-in relay, when the remote control relay 5 is switched to the on state, the lighting device is controlled to be in the lighting state.

  When the brightness change from the dark state to the bright state (second brightness change) is detected via the brightness sensor detection circuit 25 that acquires the output from the brightness sensor 2, the microcomputer 10 The OFF control instruction signal is output to the one-pulse output circuit 26 at a timing delayed by the set time B from the brightness change timing. Accordingly, a current pulse for off control is generated in the one-pulse output circuit 26. Correspondingly (specifically, in response to the fall of the voltage), the built-in relay changes from the on state to the off state. It can be switched. When the remote control relay 5 is switched to the off state in response to the relay change of the built-in relay, the lighting device is controlled to be turned off.

  Further, the configuration of the remote control system is not limited to the form shown in FIG. In the remote control system shown in FIG. 10, the commercial power supply and the remote control breaker 7 are connected to the output terminal 1j. In this remote control system, unlike the remote control system shown in FIG. 1, a commercial power supply of AC 100V is connected to the output terminal 1j, and the commercial power supply is supplied to the remote control switch 8 and the remote control breaker 7. The remote control switch 8 is configured to operate with a commercial power source. The remote control breaker 7 can be cut off when the current value supplied via the scheduled time control unit 1 exceeds a predetermined value, and can realize the same function as that of the above-described embodiment. In this remote control system, the remote control breaker 7 is connected to the one-pulse output circuit 26.
