Description

[Detailed Description of the Invention] This invention relates to an automatic lighting control device that performs time control operations of a device that centrally controls lighting equipment.

In recent years, in order to eliminate unnecessary lighting from an energy-saving perspective, many devices have been seen that perform intensive blinking and dimming control, such as controlling lights according to time of day or controlling the use of daylight.

In the time control operation of this type of device, when the lighting equipment is manually controlled during time control, there are some that manually control all of the lighting equipment, others that manually control only a part, and some that manually control only a part of the lighting equipment. In the case of,
When there is a next time control command after manual control, the previous manual control is canceled and the time control is returned to.

This invention combines the above-mentioned time and manual control by configuring that when manual settings are made during time control, the set lighting equipment is removed from time control and retains the manual settings until a certain time. An object of the present invention is to provide an automatic lighting control device that can perform controlled control operations, automatically return to time control at a certain time, and perform convenient lighting control.

Embodiments of the automatic lighting control device of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of one embodiment of the invention. In FIG. 1, 1 is a lighting device consisting of lighting fixtures 1a to 1d, each connected to an independent electric circuit, and 2 is a lighting system that is controlled according to the time of day. A setting section 3 has a key switch for setting and setting manual control A, and a clock generating section 3 generates pulses at a constant cycle.

Reference numeral 4 denotes a processing section composed of a microcomputer using a stored/program method.This processing section 4 has a setting section 2 and a clock generation section 3 connected to its input side, and a display section 5 and a driving section 6 on its output side. is connected, reads the setting output of the setting section 2 and the pulse of the clock generator 3, and performs time control processing.
It performs manual control processing and outputs blinking, dimming control signals, and control status.

Further, 5 is a display unit that displays the control status output from the processing unit 4, and this display unit 5 has an indicator LED ₁ that displays the time control mode and an indicator LED ₂ that displays the manual control mode. There is.

The driving unit 6 is the lighting equipment 1a to 1d from the processing unit 4.
The lighting device 1 is controlled by a control output corresponding to the above, and the lighting device 1 is controlled to perform blinking dimming control. Note that 7 is a power source for the lighting device 1.

Next, the operation of the automatic lighting control device of this invention constructed as above will be explained. Setting section 2
When the current time is read into the processing section 4 by operating the key switch, the set time is displayed on the display section 5 through internal program processing, and a time counting operation is started to start clock operation.

Next, the key switch of the setting section 2 is operated to set a time program for time control. That is, the processing unit 4 is made to read a series of time programs such as at what hour and minute the lighting fixture 1a of the first circuit of the lighting device 1 is dimmed, and at what time the next timer time is set, the lighting fixture 1a of the first circuit is to be turned off.

When the timer setting as described above is completed, the timer operation is started by a time control mode command from the setting section 2. That is, the microcomputer of the processing unit 4 constantly compares and matches the current time and the timer time, and if they match, outputs a blinking and dimming signal to the corresponding circuit, and the driving unit 6 controls the lighting equipment of the lighting device 1. It controls the

In executing the manual control mode, by operating the key switch of the setting section 2, the lighting device 1 is freely designated to blink or dim, and the lighting device 1 is controlled via the drive section 6 through the control processing to the processing section 4. be.

In addition, the display LED ₁ and LED ₂ of the display unit 5 are connected to the processing unit 4.
Displayed in time-of-day control mode by signals from
LED ₁ is lit, and in manual control mode, display LED ₂ is lit to notify the operating mode.

The above is the main operation of the automatic lighting control device of this invention. Next, the operation when manual control is set in the time control mode of the automatic lighting control device of this invention will be explained.

Fig. 2 is an operation timing chart for this operation, Fig. 2a shows the time transition, Fig. 2b shows the time and manual control mode, Fig. 2c shows the manual setting operation, and Fig. 2d shows the operation timing chart. Display indicating that time control is in progress
The operation of LSD ₁ is shown, and FIG. 2e shows the operation of LSD ₂ with an indication that it is under manual control.

Now, in the time control mode, if you operate the key switch of the setting section 2 at timing t1 in Fig. ₂ to manually set it, this setting will become effective (for example,
Manually set to off and dimmed on), the control of the lighting equipment is changed.

At this time, the manual control mode is displayed on the display section 5.
LED ₂ changes from off to on, and both light up together with the lighting of time control mode display LED ₁ , indicating to the operator that the time control mode has been manually set.

Next, at the _t2 timing when the time reaches 0:00 a.m., the previous manual settings are canceled and all circuits return to time control mode (those that were manually dimmed are turned on at 0:00 a.m.). ), the manual control mode display LED ₂ of the display section 5 is turned off, and only the time control mode display LED ₁ is lit.

FIG. 3 is a flowchart showing the operation routine when manual setting is performed during the time control mode of the processing unit 4. There is a mode determination 8 to determine whether the current mode is time/manual mode, and manual setting in time mode. Presence determination operation 9, operation 1 of adding manual setting to time control
0, an operation 11 for determining whether the time is 0:00 a.m., and an operation 12 for canceling the manual setting and returning to time control if it is 0:00 a.m.

Through the above operations, both time control and manual control can be performed, and not only time control but also manual setting can be performed, and the necessary lighting can be precisely controlled.

In the above-described embodiment, the time at which the manual setting is canceled is 0:00 a.m., but the time is not limited to this and may be set to another time as necessary.

As described above, according to the automatic lighting control device of this invention, in a device that controls lighting equipment to flicker or dim according to the time or manually, if a command for manual setting is received during time control, manual setting is performed. From then on, the lighting equipment that has been set up will be under manual control until a certain predetermined time is reached, after which it will return to time control, and until then, both the time control display and manual control display will light up. A combination of time control and manual control is possible. Furthermore, since the system automatically returns to time control at a certain time, more convenient lighting control can be performed.
