DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting load control device in which lighting loads placed in a building are centrally controlled from a base unit, and the present invention relates to a lighting load control device that centrally controls lighting loads placed in a building from a base unit, and which does not overlap with single-priority pattern control. By making it possible to selectively switch between possible pattern control settings, it is possible to change the pattern control state sequentially for the entire building, such as in a factory or office, or for each part of the building, such as in a gymnasium. An object of the present invention is to provide a lighting load control device that can be used for general purposes by appropriately switching between cases where lighting patterns are controlled to enable multiple uses within a building. It is.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic diagram showing a basic configuration example of an embodiment of the present invention, and in this configuration example, a power line 14 branched by a distribution board 13
The main unit 4 is operated with the power of 51, 52, etc., as shown in Fig. 2a, full-wave rectify the power sent from the base unit via the dedicated two wires 6 using the baseband transmission method, and use it as a power source for its own operation, and also use this signal. The lighting load 1 is connected to the lighting device 1 and controls the lighting load 1. That is, in this configuration example, each lighting load 1 as one control unit is assigned a serial number and is individually assigned to the base unit 4.
The terminals 51, 52 are controlled from the side, and use a baseband transmission system using dedicated two wires 6 as a multiplex transmission system to simultaneously transmit operating power and data. However, the present invention is not limited to such embodiments; power and data may be transmitted separately, or a power line carrier method or a wireless transmission method may be used. In addition, a multiplexing method based on frequency division may also be used. Thus, in the configuration example shown in FIG. 1, the master device 4 is configured with a built-in microprocessor 7 as described later, and for example, as shown in FIG. 2a, one terminal device 51, 52, . . . - Hit, 1-bit pulse of logical value RlJ as start pulse, predetermined control butter. 8-bit address data for selecting signals 51, 52, . . ., 1-bit pulse of 1-bit address parity logical value RL, and the called control pattern 5, 52, . 5-bit control data that sets the control content in CDll bit control data parity CPl is the waiting period for the return signal.
A signal consisting of 6-bit long pulses arranged in series is sent out, and this signal is sent out cyclically and repeatedly one after another for each address.

In addition, in the case of this configuration example, each control pattern 51, 52,
... takes in the signal on the dedicated 2-wire 6 as described above and determines whether or not it is calling itself from the data contents of the address data pigeon, and when it is determined that it is calling itself, it changes the contents of the control data CD. Therefore, the lighting load 1... is controlled to turn on and off, and one control pattern 51,
The lighting load 1 as four control units is controlled every 52.... Here, one control unit is the smallest unit that can be individually controlled in the terminal device 51...
In the case of the above configuration example, on/off control is performed depending on whether or not there is a pulse of logical value RlJ in the corresponding bit in the control data CD, and the fifth bit of the control data CD is not related to the present invention. Since it is used for other purposes, it has four control units, and in reality, any number of controlled loads may be connected in parallel to this one control unit, but in the following explanation, , one lighting load 1 will be representatively explained for each control unit. In addition, each lighting load 1
(Lighting load 1 as a control unit) is assigned a serial number starting from 1, and depending on the number of lighting load 1, the master unit 4
Pattern control and individual manual control as needed are performed from the side, and for example, the control content for lighting each of the third to ninth lighting loads 1 as the first pattern in the base unit 4 is stored in the first pattern storage section. 181, and if the first pattern selection switch 221 is operated to turn on the first pattern, the selection indicator light 241 attached to the first pattern selection switch 221 will be turned on, and the first pattern will be turned on. When setting addresses to call the first, second, and third terminals 51, 52, and 53, each lighting load 1 to be lit is set as control data CD following the address data.・It creates data for lighting up and sends it out as a baseband signal as shown in Figure 2a, and each terminal device 51, 5
2, 53 receives this, and when it is determined that its own terminal device 51... has been called, the control data C
The lighting of each lighting load 1 is controlled according to the contents of D. Since this individual calling control from the base unit 4 to each terminal unit 51, 52, 53 is performed at high speed, visually, the third to ninth lighting loads 1... are almost all all at once. It will be lit. Next, 15 is a wall switch, which is actually a terminal device 51,5. It has a circuit configuration similar to that of . ,1
5b is configured such that the two dedicated wires 6 are short-circuited during the long pulse sending period from the base unit 4 side, and the return signal is transmitted as data in the current mode as shown in FIG. 2b. The return signal sent back in the current mode is received by the base unit 4, and each time each operation switch 15a, 15b is operated, the lighting load 1 of the number subordinated to that operation switch 15a, 15b... (This dependent relationship is programmed in the base unit 4 in advance) In the same way as described above, the base unit 4 sends the terminal device 51 to which the lighting load 1 belongs... A control data CD will be created and sent out. Note that although the wall switch 15 is configured to have the same address as an appropriate terminal device 51 that does not have a monitoring function, it is configured to have a completely different address from the terminal device 51. Also good. FIG. 3 shows the circuit configuration inside the base unit 4, which includes a microprocessor 7, a storage section 8, a clock section 9, a display section 10, a key switch 11, a control switch section 16, and first to Nth pattern selection switches. 221 to 22N, etc., and converts the data signal created by the microprocessor 7 and its attached circuits into baseband data as shown in FIG.

A current mode return signal as shown in FIG. b is received and this received data is input to the microprocessor 7.

The storage unit 8 may be constructed using the RAM itself if there is sufficient RAM in the microprocessor 7, but the first to Nth pattern storage units 181,
...18N1 all release storage unit 1801 wall switch correspondence relationship storage unit 19, first to Nth pattern storage unit 181
. . 18N stores the number of lighting load 1 . The wall switch correspondence storage unit 19 stores data for turning off all lighting loads 1 (a kind of pattern control data) and data for the time at which all of them should be turned off. Regarding the switch 15, when the respective operation switch 15a, 15b is operated, the correspondence relationship as to which lighting load 1 should be blinked is stored. The timekeeping section 9 inputs data regarding the day of the week, hours, and minutes to the microprocessor 7, and the microprocessor 7 normally inputs time data from the timekeeping section 9 or from the first to Nth pattern selection switches 221 to 22N. The pattern selection data is input to determine which control is to be performed among the pattern controls stored in the first to Nth pattern storage sections 181, 18N and the all cancellation storage section 180, and the determined pattern control is executed. At the same time, a return signal from the wall switch 15 is received, and based on the content of the return signal, the wall switch correspondence storage section 19 is accessed to turn on which lighting load 1... terminal device 5 to which the determined lighting load 1 belongs.
When calling 1,52..., the lighting load 1...
A control data CD for lighting the... is created and sent out. On the other hand, the display section 10 normally displays the output time data from the timekeeping section 9 as is, and functions as a clock. When the control switch section 16 is set to the time setting mode, a change point setting switch (not shown) in the control switch section 16 sets the 1st day of the week, 1 o'clock, 1
The time is set by setting whether to change to 10th of a minute or 100th of a minute, and then operating the up count button or down count button (both not shown) to set the time. , the state of time adjustment at this time is displayed on the display section 10. Next, when the control switch section 16 is set to the pattern setting mode, first, by operating the key switch 11, the memory section 18 of one of the pattern controls is displayed.
0 to 18N is selected, and the stored start time of the pattern control is displayed on the display section 10. If you wish to change this time, change the pattern control in the same manner as when setting the time in a. Reset the start time. On the other hand, the lighting load 1 controlled in the pattern control

After setting the lighting load 1... number change setting state, use key switch 11 to turn on (in addition to pattern control) or turn off (remove from pattern control)
Input the number of lighting load 1... and complete the pattern setting. Also, to change the contents stored in the wall switch correspondence storage section 19, the control switch section 16 is set to the wall switch correspondence change setting mode, and the change setting of the correspondence relationship is performed by operating the key switch 11 in the same manner as described above. It will be done. Furthermore, in the present invention, when the control switch section 16 is set to the manual state,
First to Nth pattern selection switches 221 to 22N or all release switch 22 corresponding to the first to Nth patterns or all release, respectively. By operating , it is possible to perform the operation either alternatively or redundantly, regardless of the time limit setting time set and stored in the storage unit 8, and this alternative (
A setting changeover switch 23 is provided so that it is possible to select whether to perform single pattern control (single pattern control) or redundant pattern control. Further, each selection indicator light 24 corresponds to each of the first to Nth pattern selection switches 221 to 22N.
1 to 24N are attached, and these pattern selection switches 2
21 to 22N, or as described above, the microprocessor 7 determines whether the set time data from the first to Nth pattern storage units 181 to 18 match the current time data from the timer unit 9. As a result, when the first to Nth control patterns are selected, the corresponding selection indicator lights 2 to 24N are lit. The setting changeover switch 23 is constituted by a depth switch attached to a printed circuit board (not shown) on which the microprocessor 7 is mounted, and the microprocessor 7 monitors which setting state the setting changeover switch 23 is in. , and when the setting changeover switch 23 is on the alternative (priority after single) side, the next Nth control pattern is selected in the state in which the first control pattern is selected by operating the pattern selection switch 221, for example. When the pattern selection switch 22N is operated as desired, the blinking state of the lighting load 1 . . . according to the previous control pattern is canceled and the corresponding selection indicator light 241 is turned off. Then, according to the Nth control pattern, the lighting loads 1 . . . are turned on or off, and the selection indicator lamp 24N is turned on. On the other hand, when the setting changeover switch 23 is on the duplication side, for example, after operating the first pattern selection switch 221, the second pattern selection switch 221 is operated. When the switch 222 is operated, the first
In addition to the pattern control state according to the first control pattern selected by the pattern selection switch 221, the pattern control state according to the second control pattern selected by the second pattern selection switch 222 is overlapped and performed, respectively. Both of the selection indicator lights 241 and 242 attached to both pattern selection switches 221 and 222 are turned on. Note that when the control switch unit 16 is operated to set manual operation, the individual lighting loads can be turned on or off one by one by operating the key switch 11. FIG. 7 is a flowchart showing the operation of alternative selection and duplicate selection, and the processing operation of the microprocessor 7 is performed in the pattern storage unit based on the currently selected control pattern number (instructed by the control pattern group). 8, the stored data is successively outputted to create the signal shown in FIG. Here, if the setting changeover switch 23 is set to the alternative side, the previously selected control pattern is reset and the currently selected control pattern is set as the lighting pattern NO group. On the other hand, when the setting changeover switch 23 is set to the duplication selection side, in addition to the previously selected control pattern, the currently selected control pattern is also set as the lighting pattern NO group. There is. Thus, Figure 4 a-
e shows an example of the lighting state of each pattern when "5 pattern control is performed as time control in a state where the setting changeover switch 23 is set to alternative (single priority),"
The blacked-out portion in the figure shows the lighting load 1 in the off state.

In addition, in Fig. 4 a-e, the lighting load 1 on the floor in the building...
. . . is pattern-controlled. Therefore, Figure 4a
At around 8:00 as shown in Figure 4, all lights are off, and at 8:00, 20% of the lighting load is automatically turned on in preparation for cleaning etc. as shown in Figure 4a. Next, at 8:30 a.m., the morning work begins, and the lighting load 1 is turned on at 80% as shown in Figure b, partially utilizing outside light. Furthermore, at 12:00, when it is lunch break,
90% of the lighting load 1... is turned off as shown in
When the afternoon shift begins at 13:00, the lights are turned on at 60%, as shown in Figure d, using relatively strong outside light. After that, at 18:00, when it is time for overtime work, only the lighting load 1... in the area where overtime work is to be done is turned on as shown in e of the same figure (at this time, if necessary, the wall switch 1
5), all lights will be turned off at 22:00.
If it is set to 0, all lighting loads 1, including lighting loads 1, which were turned on by the wall switch 15 at this time, will be forcibly turned off. This will prevent you from forgetting to turn it off.
