Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pattern control circuit for lighting loads that controls on and off a large number of lighting loads based on predetermined pattern data. We have developed a pattern control circuit for lighting loads that can automatically control each lighting load in a pattern by presetting the on/off control status of the load in the pattern setting switch and providing a one-shot input. In the next case, if the pattern control circuit is operated by the output of an automatic operation switch such as a timer or sensor, an inconvenience may occur where the lighting load is turned off even though there is a person present. It's hot.

The present invention has been made to solve the problems of the conventional example, and it is possible to select whether or not to pattern control each lighting load, and to control the pattern control circuit of the lighting loads. The purpose is to provide

The configuration of the present invention will be described below with reference to illustrated embodiments. 1st
3 through 3 are circuit diagrams showing one embodiment of the present invention.

First, in Fig. 1, R)'i-R)'s is a seven-contact relay consisting of a single-winding type latching relay, and its output contacts "is to ry" are used to control the lighting load L.
! ~Lm is controlled to turn off. The output contacts ryI to ``Is are turned on or off depending on the direction of the current flowing through the excitation coil, and the state Im is maintained.r''-'r is the latching XS X@ Auxiliary contact of relays Ry1 to Ry8, output contact r
It is designed to switch each time y, ~ryll is turned on or off. A pair of diodes are connected in antiparallel to each of the auxiliary contacts rX1 to rX10 switching contacts. m1 to m8 are switches for manual operation,

A pair of diodes are connected in antiparallel to both switching contacts of 1nl, respectively, and the common contact of each switch m1 to gull is normally set at a neutral position. When the common contact of the switches m1 to mIl is switched and connected to one of the switching contacts, a current flows in the rectifying direction of the friend diode connected to the switching contact, causing each ℃con relay R)'!
'Rys are controlled to be turned on and off individually.

Next, in FIG. 2, SWo is an operation switch circuit,
It is commonly connected to each of the seven contact relays Ry5-Rys shown in Fig. tIIJ1 via an AC 24V AC power source and a terminal Trnok. This operation switch circuit SW.

is composed of an on contact nail and a contact fr controlled by an on relay NR and an off relay FR, and diodes connected in series to each contact and having opposite polarities to each other. Switch operation circuit 8Wo and each terminal T
Triacs T1 to T8 are inserted and connected in series between rn1 to TmH, and these triacs T1 to TmH are inserted and connected in series.
When T@ is turned on, the on contact nrt or the off contact fr
The direction of the current flowing through the seven-contact relay Ryl-R7@ (n excitation coil is determined depending on which one is closed. Q1 to QB are the triacs T1 to Tst on/off) This is a transistor. The base of each transistor Ql-Qs is 10
It is connected to each output of the 1st digit to the 8th digit of the advance counter CT. This decimal counter CT is the oscillator O8C in Fig. 3.
It is counted up sequentially from the glue output CLKK,
This is to turn on any one of the triacs Ts''TS in sequence.Next, PDt and PDt are pattern setting switches that respectively set the on/off status 1M of the lighting loads L1 to Ij, and are composed of chip switches. AI and A10 are AND circuits, and when the output of AND circuit A9 goes to H level, the setting contents of pattern setting switch P Dl are input to AND circuits A1 to A8, and conversely, the output of AND circuit Aso goes to H level. When the level is reached, the settings of the pattern setting switch PDt are input to the AND circuit A.
]~Pattern setting switch PD+, P input to A8
The setting contents of Ih are set so that if it is at H level, the corresponding lighting loads Ll to Ls are turned on, and if it is at L level, the corresponding lighting loads Ll to Lsi are turned off. The other input of the AND circuit A+~As is a decimal counter C.
The outputs of each digit of T are connected respectively, and the input from this decimal counter CT and the pattern setting switch PD+
When the input from 5PIh becomes H level at the same time, the output of the AND circuits A1 to As becomes H level,
The ON relay NR is driven through the transistor Q9t, and the oscillator contact nr is closed. At this time, since any one of the triacs T1 to Ts is conductive due to the output of the decimal factor CT, that triac Ts
- The lighting loads Ll to Ls corresponding to Ts are turned on. Next, the outputs of the AND circuit A t-A s are each connected to one input of the exclusive OR circuit X I-X s,
The output of each digit of the decimal counter CT is connected to the other input of the exclusive OR circuit X1-Xρ. Therefore, the exclusive OR circuits X1 to h are connected to the decimal counter C
When the input from T is at H level and the input from pattern setting switch PDISPD2 is at L level, the output goes to H level, which causes transistor Q

The OFF contact fr is driven via the OFF contact fr. At this time, according to the output of the decimal counter CT, since any one of the triacs T+"Ts is conducting, the lighting loads L1 to L8 corresponding to the triacs T1 to T- are turned off. Note that each relay NR, The drive timing of the PR and the drive timing of the transistor Qt-Q@ are the transistor Q operated by the output CLK of the oscillator osc.

and Q10. As will be described later, 7tQ+z is a transistor that is always on.

Next, in FIG. 2, 81 to s8 are lighting loads L+-Ls(
Each lighting load L determines whether or not pattern control is to be performed depending on the settings to the H base setting switch P DllftFiP.
This is the next selection switch that individually selects 1 to L8. When all of the selection switches 81 to s8 are turned off, each lighting load Lt to b is set to the pattern setting switch trich PD+t7t is PD! The pattern is controlled according to the settings of the selection switch S+-''.
If -88 is turned on, the corresponding AND circuit A1~
Since A8 and one input of the exclusive OR circuits XI-, Xs are always at L level, the corresponding lighting load L+-Ls
pattern control is not performed. Lighting load L
Among 1 to L8, selection switch Sl-5ll corresponds to a lighting load installed in a private room where no one is always present, such as a toy bathroom, and where the lighting load is turned off by pattern control.
If you turn it on, when there is someone in the room by chance,
This prevents the illumination loads L1 to L8 from being suddenly turned off by pattern control. Furthermore, it is convenient to use human body detection sensors installed in the private room as the selection switches 81 to S8, since the pattern control can be stopped only when a person is present. □ Next, in Figure @3, O20 is an oscillator made up of a NAND gate and a CR element, and sends out a 90x output CLKI to the 1o-adic counter CT, transistors Qll, and O13 in Figure 2. This oscillator O8C is a flip-flop connected via an OR gate.
When any of the outputs f1 to f4 of the oscillator 4 is at H level, automatic oscillation is performed, and when the output fs"fi is at L level, self-oscillation is stopped. When the oscillator OSC performs self-oscillation, the second One of the 1st to 9th digits of the decimal counter CT shown in the figure goes to H level in sequence, and when the 9th digit goes to H level, it is reset via a delay circuit consisting of a CR integration circuit and a NAND gate. Terminal R8 becomes H level, and decimal counter CT and each flip-flop

4 are connected via a diode-or circuit, and each output f+ of flip-flops Fs to FF4 is connected in a circle.
Only one of -fi can be at H level. A T+ , A Tt are automatically actuated switches such as timers or sensors, and P+, Pt are first and second pattern control switches 1ν that are closed only for a short time when the automatically actuated switches A T+ , A T2 are activated.
It is Chi. The flip-flops FFs and FF4 are set via the photocouplers Pel and P(!4) when the pattern control switches PI and Pt are turned on, and when set, the outputs f8 and f4 become H level, respectively. When f3 becomes H level, the output of the 1-AND circuit becomes H level, and the settings of the pattern setting switch PDI are input to the AND circuits A1 to A8.tX output f4
When becomes H level, the output of AND circuit Alo becomes H level, and the setting contents of pattern setting switch PIh are input to AND circuits A1 to As. t ft Ns

-F Fz is set, and when set, the outputs fl and h are each at H level.
+ is set and the output f1 becomes H level, the transistor Qe turns on, so the on relay NR operates during the full power period of the decimal counter CT, turning on all the lighting loads L+'' LP. become.

At this time, the inverted output of flip-flop F Fl is 1.1
Since Q1da is at the L level, the transistor Q1da, which is normally on, is turned off, and the off relay PR is not activated. On the other hand, when the flip-flop FF2 is set and the output fz becomes H level, the transistor Ql.

is turned on, the off relays FR are activated for all of the digits and g's of the decimal counter CT, and all the lighting loads L+-Ls are turned off. The operation of the pattern control circuit can be monitored by external equipment (not shown) via the terminal Ko=KAf. The collectors of transistors Q+s-Q+p are connected to each terminal 1 to 4, and the emitters of each transistor Q+5 to Q+s are connected to a common terminal Ko via a transistor Qta. At the base of each transistor Q+s to QCs, there is a flip-flop 0 tsu FF.
f4 is connected. The output of the ninth digit of the decimal counter CT is applied to the base of the transistor Q14. Therefore, when the decimal counter CT completes counting and the output of the 9th digit becomes H level,
Transistors Q and 4 turn on, and at this time the output f1~
The transistor Q +a '' Q +s corresponding to the H level output of f4 is turned on.Therefore, conduction is established between any one of the terminals + to 4 and the common terminal Ko, and the pattern control circuit Operation can be monitored from the outside.

Furthermore, in Fig. 3, PW is a power supply circuit, and AC24
The AC power source V is half-wave rectified by the diode Pat and smoothed by the capacitor O, and the DC voltage is supplied to the relays FR and NR via the terminal Vat-.

The output voltage of a constant voltage circuit consisting of a transistor Qll and a Zener diode ZDgin is supplied to the gates of each of the triacs T1 to Ts through a terminal 2, and also serves as an operating power source for each part. Note that 2NR is a noise prevention element.

The present invention is configured as described above, and includes a plurality of lighting loads that can be individually controlled on and off manually, a pattern setting switch that presets the on/off pattern of each lighting load, and a timer, sensor, etc. an automatic operation switch, a pattern control means for individually controlling on/off of each lighting load according to the settings of the pattern setting switch when the automatic operation switch is operated, and a pattern control means for individually controlling on/off of each lighting load according to the settings of the pattern setting switch when the automatic operation switch is operated; It is equipped with a selection switch for individually selecting the lighting load, and is as follows:
By operating a selection switch corresponding to a specific lighting load among multiple lighting loads, that lighting load can be excluded from pattern control, and therefore, by operating an automatic activation switch, lighting in places where people are present can be excluded. This has the advantage that it is possible to eliminate the inconvenience of having the load turned off. As mentioned in the explanation of the embodiment,
If a human body detection sensor installed in a single cubicle is used as a selection switch that corresponds to the lighting load installed in a private room such as a toilet or bathroom that is usually unoccupied, the cubicle will only be activated when a person is present. This is very advantageous because the lighting load can be excluded from pattern control.
