The present invention relates to a pattern selection method for a remote control relay, characterized in that the polarity switching circuit is controlled by the output of the polarity switching circuit.

The purpose of the present invention is to turn on the remote control relay.
The purpose of the present invention is to facilitate pattern control in which three modes other than OFF and ELAYA can be selected. Generally, pattern control requires on, off, and out-of-field settings. Particularly when used in a general household, if you want to control patterns using emergency signals for crime prevention, disaster prevention, etc., select the pattern you want to turn on in an emergency, and the other parts will turn off. In particular, I often don't turn on things like the toilet. Therefore, for patterns that occur in an emergency, it may be inconvenient to turn on and off only, and an error mode is required for areas other than those that must be turned on, and three modes are required. The present invention has been made in view of this point, and allows selection of these three modes.

First, let's talk about the pattern control device for remote control relays.
This will be explained using the block circuit shown in the figure. In FIG. 1, numeral 1 denotes a pattern input switch, which is composed of a manual switch, a fire detector, etc., and this input is held by a holding circuit 2 formed of a flip-flop. These pattern input switches 1
, a plurality of holding circuits 2 are provided as necessary. Reference numeral 3 denotes an oscillation circuit, which starts to be driven by the output of the holding circuit 2, inputs its output to the binary counter 5 via the frequency dividing circuit 4, and sequentially outputs outputs from the binary counter 5.

A remote control relay drive circuit 6 is serially controlled by the output of the binary counter 5, and the remote control relay 7 is operated by the output of the remote control relay drive circuit 6 and a polarity changing circuit 101 to be described later.

Reference numeral 8 designates a pattern setting switch, which is a dip switch or other alternate switch, and is serially controlled by the output of the holding circuit 2, and the output of the pattern setting switch 8 causes the remote control discriminating circuit 9 to operate serially.

Reference numeral 10 denotes a polarity discrimination circuit, which is controlled by the output of the polarity discrimination circuit 9 and controls the remote control relay 7.

The remote control relay 7 has a polarity switching circuit 10 as shown in FIG.
A closed circuit is formed by connecting diodes D,,02 in series with the contacts Ry,',Ry2' of the relays Ry,,Ry2 in opposite directions, respectively, and the thyristor 11 of the remote control relay drive circuit 6. It is driven by the outputs of the drive circuit 6 and the polarity switching circuit 10 to turn on and off a load (not shown). Incidentally, the remote control relay 7 uses a latching relay, and a plurality of them may be used as necessary.
Further, a plurality of pattern setting switches 8 may be used as required. In the pattern control device as described above, since the load is controlled on and off according to the pattern input switch and the pattern setting switch 8, it is not possible to control the outside mode. Therefore, in the present invention, as shown in FIG. Control 10. That is, this output and the output of the binary counter 5 are ANDed to select whether the pattern setting switch 8a is on or off.
and EXOR, and when the pattern setting switch 8a is in the normal position, the output of the AND circuit is 1, and the relay Ry2 operates to control the remote control relay 7 to the on side, and when the pattern setting switch 8a is in the OFF position, the output of the EXOR circuit is , the relay Ry operates and controls the remote control relay 7 to the OFF side. Next, the other switch 8b of the pattern setting switch 8 is used for selecting outside the area, and its output and the output of the binary counter 5 are connected to the AND circuit 12.
and its output is inputted via the OR circuit 13 to the base of the transistor Q connected in series with the transistors Q, , Q2 of the polarity switching circuit 10. Therefore, when the pattern setting switch 8b is on, the relay Ry or Ry2
can operate and give an on/off signal to the remote control relay 7. Furthermore, when the pattern setting switch 8b is off, the relay Ry. , Ry2 stops operating and does not give a signal to the remote control relay 7. In the manner described above, the remote control relay 7 can be controlled to be turned on, turned off, and selectively controlled. Next, FIG. 4 shows another embodiment of the present invention, in which the output of the pattern setting switch 8b and the output of the binary counter 5 are inputted to the polarity discrimination circuit 9 via the AND circuit 12. , when the pattern setting switch 8b is off, the AND circuit of the polarity discrimination circuit 9 and the EXO
The output of the R circuit becomes L, and the relays Ry, , Ry2 do not operate and do not provide a signal to the remote control relay 7.

Therefore, it is possible to select and control three modes: on, off, and off. As described above, the present invention has two pattern setting switches in one set, and the output of one pattern setting switch controls the polarity switching circuit via the polarity discrimination circuit. Since the polarity switching circuit is controlled by the output obtained through the AND circuit of the output of This has the effect of making it possible.
