を目的とするものである。 The operation of the conventional example is explained below.
When the relay contact 5 is in the off state and the hand switch 4 of the load 3 connected to the outlet 8 is turned off, current flows to the resistor 13 via the resistors 11 and 12 along the path shown by the solid arrow X in the figure. flows,
Only when the B side of the AC power source 1 is at a positive potential, a voltage appears across the resistor 13, and the voltage across the resistor 13 becomes a half-wave rectified voltage AC1 of the AC power source voltage, as shown in FIG. 3a. Next, when the hand switch 4 is turned on, current flows to the resistor 13 via the load 3 and the resistor 12 along the path shown by the solid arrow X and the dotted arrow Y, and the voltage across the resistor 13 is As shown in , the AC power supply voltage becomes a full-wave rectified AC 2 voltage. The voltage waveform in FIG. 3b shows the case where the hand switch 4 is turned on at point S. The voltage across the resistor 13 is waveform-shaped by the converter 14, so that when the load 3 is connected to the outlet 8, as shown in FIG. A detection signal V L is obtained,
When the load 3 is not connected to the outlet 8, a connection detection signal VL consisting of digital data in which "1" and "0" (L level) are alternately successive is obtained. The connection detection signal V L thus obtained is sequentially read into a shift register 15' which receives the power synchronization signal V ck as a clock input.
Four successive bits of the connection detection signal V L are simultaneously output to each bit output of the shift register 15', and the ON detection circuit 1 consisting of an AND gate is output.
Turning on of the hand switch 4 is detected by calculating the AND of each bit output at 6'. That is, when the hand switch 4 is turned on, the connection detection signal V L in which 4 or more bits of "1" are consecutive is read into the shift register 15', and each bit output of the shift register 15' becomes all "1".
The output of the on-detection circuit 16' becomes "1" only when the on-state detection circuit 16' becomes "1". In this case, when the hand switch 4 is off, two bits of each bit output of the shift register 15' are output as "0", so the output of the on-detection circuit 16' is "0". The latching relay is controlled by this ON detection circuit 16' output V ON , and the ON detection circuit 16' output V ON
The relay contact 5 of the latching relay is turned on at the rising edge of the relay control signal V R . Therefore, relay contact 5 is activated by hand switch 4.
When turning on load 3 by turning on, turning off hand switch 4 and turning it on again activates the latching relay, turns on relay contact 5, and turns on load 3. . By the way, in such a conventional example, as shown in FIG . By setting the bits appropriately (for example, setting the number of bits to 4 for one noise N1 ), the relay control signal V R will not be affected and malfunction of the hand control circuit can be prevented, but the connection detection signal V When noise N2 that changes L from "1" to "0" is input, the output of the on-detection circuit 16' becomes "0" in the tN interval due to the influence of the noise N2 , and the hand switch 4 is The problem is that a malfunction occurs in which the latching relay is activated and load 3 is turned on even though it is not being operated, and this malfunction cannot be prevented even by increasing the number of bits in the shift register 15'. It was hot. The present invention aims to solve the above problems.

ている。 Examples will be described below using figures. 6th
9 to 9 show the main circuit diagram and operation of an embodiment of the present invention, and the schematic configuration of the remote control device and the load connection detection circuit 6 are the same as those of the conventional example shown in FIGS. 1 and 2. Therefore, the explanation of the configuration and operation will be omitted. FIG. 6 shows a 2-bit shift register 15, an on-detection circuit 16, and an off-detection circuit 17.
The shift register 15 is configured to sequentially read each bit of the connection detection signal V L output from the load connection detection circuit 6 in synchronization with the power synchronization signal Vck, as in the conventional example. It's summery. The ON detection circuit 16 consisting of an AND gate takes the AND of each bit output of the shift register 15, and outputs an ON detection signal Von which becomes "1" when the bit output is "1" and "1". It's summery. The off detection circuit 17 consisting of an exclusive OR gate is connected to the shift register 15.
The off detection signal V pff which becomes "1" when the bit output is "1" or "0" is output. Reference numeral 19 denotes a malfunction prevention circuit, which is composed of an on confirmation circuit 20 and an off confirmation circuit 21 consisting of a counter circuit C with a reset terminal RST, and an output circuit 22 consisting of an S-R flip-flop.
The counter circuits C 0 and 21 are designed to count the power synchronization signal Vck, and are connected to the reset terminal.
Power supply synchronization signal from the moment RST becomes L level
A count-up output is obtained when a predetermined number of Vck is counted, and it is an ON and OFF detection signal.
It is designed to confirm that Von, V pff have been obtained for a certain period of time or more, and the output of the off confirmation circuit 21 is set to R.
- The output of the on-confirmation circuit 20 is input to the set terminal S of the R-S flip-flop F, and the output signal output from the latter of the two confirmation circuits 20 and 21 is input to the reset terminal R of the -S flip-flop F. It's starting to latch on. Therefore, when the output of the ON confirmation circuit 20 is obtained after the output of the OFF confirmation circuit 21 is obtained, the output of the output circuit 22 changes from "0" to "1" and the malfunction prevention circuit 19
A relay control signal V R is output from.

Now, when the connection detection signal V L changes due to noises N 1 and N 2 , the on detection signal Von and the off detection signal V pff correspond to the noises N 1 and N 2 , respectively, as shown in b and d of the same figure. However, the outputs of the ON confirmation circuit 20 and OFF confirmation circuit 21 are as shown in c and e in the figure, and the relay control signal V R output from the output circuit 22 is affected by noise as shown in f in the figure. First, the relay contact 5 will not malfunction. Note that increasing the count number of the counter circuit C will reliably prevent malfunctions when noises N 1 and N 2 are continuously input, but the load 3
It is necessary to lengthen the on time of the hand switch 4 when the hand switch 4 is operated in accordance with the count number.

This has the advantage that it is possible to provide a hand-operated circuit for a remote control device that does not malfunction.
