Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control relay sequential control system.

In recent years, loads such as lamps have been controlled in patterns such as all lights on, all lights off, or dimly lit. However, since the number of loads to be controlled with one pattern varies depending on the size of the building, it is necessary to accommodate this.

The present invention has been made in view of this point, and its purpose is to form a basic unit with, for example, eight loads that can be controlled in one pattern,
The idea is to connect a plurality of these basic units in sequence to cope with the number of loads. This will be explained in detail below using examples.

In FIG. 1, reference numerals 1a, 1b, and 1c are pattern input switches, respectively, which control a load (not shown) in a pattern of all lights on, all lights off, and dim lights, and these pattern input switches 1a, 1b, A holding circuit 2 formed by a flip-flop is connected to each of the holding circuits 1c. Reference numeral 3 denotes an oscillation circuit that starts driving based on the output of the holding circuit 2. 4 is a binary counter, which sequentially outputs an output based on the output of the oscillation circuit 3. Reference numeral 5 denotes a remote control relay control circuit, which is controlled by the output of the binary counter 4 and the output of the pattern setting switch 6. That is, the pattern setting switch 6 receives the output of the holding circuit 2 that holds the operating states of the pattern input switches 1a, 1b, and 1c, and the pattern setting switch 6 receives the output of the pattern input switches 1a, 1b, and 1c from the holding circuit 2 output. identify which switch was operated. In the case of all lights on or all off, that is, when the pattern input switch 1a or 1b is operated, a predetermined signal corresponding to all lights on or all off is input to the remote control relay control circuit 5, and the remote control relay control circuit 5 turns off the full load. 12 is controlled to be fully lit or completely extinguished. When the pattern input switch 1c is operated in a thinned-out mode, a deep switch corresponding to each of the total loads 12 of the basic unit is used, and the loads 12 that are set to be lit by the deep switch are turned on. It controls the remote control relay control circuit 5. Reference numeral 7 denotes a next-stage feed signal output circuit, which outputs an output by ANDing the final output of the binary counter 4 and the output of the holding circuit 2. A basic unit 8 is formed by the holding circuit 2, the oscillation circuit 3, the binary counter 4, the remote control relay control circuit 5, the pattern setting switch 6, and the next stage feed signal output circuit 7. As shown in FIG. 2, the remote control relay control circuit 5 controls the thyristor 9 to transmit the remote control relay
The load 12 is controlled by the main contact 11, and the next operation is performed by switching the auxiliary contact 13. The remote control relay 10 uses a latching relay, and the one shown in FIG. 2 shows a magnetic holding type latching relay. Although FIG. 2 shows only one thyristor 9, one remote control relay 10, and one load 12, the remote control relay control circuit 5 is designed to be able to control, for example, eight loads 12.

If the number of loads to be controlled is large due to the size of the building, a plurality of basic units 8 having the same configuration as the basic unit 8 described above may be used, and the output terminals 14a, 14b, 14c of the next stage feed signal output circuit 7 may be used. Input terminals 15a, 15b, 15c of another basic unit 8
By sequentially connecting to the building, it is possible to control the load pattern according to the size of the building.

FIG. 3 shows another embodiment of the present invention, in which transistors Q ₁ , Q ₂ , Q ₃ , and Q ₄ are used in the next stage feed signal output circuit 7, and the output terminals 14a to 14d are used to supply the next stage basic unit 8. The one shown in FIG. 3 may be used depending on the state of the input of the next stage.

As described above, the present invention comprises: a holding circuit that holds the operating state of a pattern input switch; an oscillation circuit that starts driving based on the holding output; a binary counter that sequentially outputs an output based on the output of the oscillation circuit; A basic unit comprising a remote control relay control circuit that is controlled by the output of the counter and the output of the pattern setting switch, and a next stage feed signal output circuit that outputs an output by ANDing the final output of the binary counter and the output of the holding circuit. Since we connected multiple units in sequence and controlled the loads in a pattern, for example, 8 loads could be controlled with one pattern.
The basic unit can be formed individually, and a plurality of these basic units can be connected in sequence to accommodate the number of loads depending on the size of the building.

Furthermore, the holding circuit holds the operating state of the pattern input switch, and when the final output of the binary counter is generated indicating that the sending of the control signal for operating the load of the basic unit is completed, the holding circuit output is By outputting a signal from the next stage feed signal output circuit to the next stage basic unit, it is possible to sequentially operate the load of the next stage basic unit according to the operating state of the pattern input switch. The wiring between the basic units is sufficient, and even if the load on the basic units increases, the wiring between the basic units does not increase.
