Next, an embodiment of a ceiling ceiling circuit with a wireless switch receiver according to the present invention will be described in detail.

FIG. 6 shows an electronic circuit of one embodiment of a ceiling ceiling with a wireless switch receiver according to the present invention. The receiving circuit includes a light receiving section 52, a preamplifier section 53, a demodulating section 54, a signal processing section 55, a signal generating section 56, and a switch control section 57. The light receiving section 52 is equipped with a light receiving diode (or a phototransistor),
The optical signal input to this light receiving diode is amplified by a preamplifier section 53, and then demodulated by a demodulating section 54 to a signal before modulation. This demodulated signal is
The signal is input to a signal processing section 55 mainly composed of an LSI. This signal processing section 55 outputs a received signal that is repeatedly inverted between H level and L level every time the optical signal is input to the light receiving diode. This received signal is sent to the input terminal of the signal generator 56 (point A in the figure). The signal processing section 55 includes
A clock generation circuit 59 for generating clock pulses for the LSI is connected. Signal generator 56
Then, when the received signal rises, a short-time interval energizing signal is output from the signal output terminal 7a, and when the received signal falls, a short-time interval energizing signal is also output from the signal output terminal 7b. .

The manner in which the energizing signal is generated in the signal generating section 56 will be described in detail. The activation signal is generated at the rising edge of the received signal as follows. When the input level at point A, which is the input terminal of the signal generating section 56, is at L level until it becomes H level,
Since the input N1a of the NAND element N1 is at the L level, even if the input N1b on the side where the inverting element NA is interposed is at the H level, the output of this NAND element N1 is at the H level. Since the NAND element N2 to which this H level signal is input is connected to function as an inverting element, the output level of the signal output terminal 7a of this H level N2 is at L level. When the input level at point A is inverted to H level, the input N1a of NAND element N1 becomes
Immediately, the level becomes H level, but a time constant circuit consisting of resistors R1, R2 and capacitor C1 is provided between the input terminal on the input N1b side and the inverting terminal NA, so that the output of the inverting element NA becomes H level. Since the charge accumulated in the capacitor C1 during a certain period of time is discharged through the resistors R1 and R2 from the above-mentioned inversion point, this discharge is completed to some extent, so that the input N1b of the NAND element N1 is at L level for a certain period. Instead, it is maintained at an H level. During this period, the NAND element N1 receives both inputs N11a and N1b at the H level and outputs the output at the L level. Therefore, the output level of the signal output terminal 7a of the NAND element N2 becomes H level,
An energizing signal will be generated. Capacitor C1
As the discharge progresses and the input N1b becomes L level, the output of NAND element N1 is inverted to H level, so the output level of the signal output terminal 7a of NAND element N2 becomes L level, and the energizing signal disappears. . In other words, at the time of rising, the energizing signal is generated for a short fixed period determined by the time constant circuit. On the other hand, as the input level at point A shifts to the H level, transistor Q1
As a result, the input N3a of NAND element N3 immediately
is at L level, so the output of NAND element N3 is at H level regardless of the state of input N3b. Note that an inverting element may be used instead of the transistor Q1. NAND element N4 has a connection configuration that functions as an inverting element, so this
The output of the signal output terminal 7b of the NAND element N4 is L
It remains at that level.

The activation signal is generated at the falling edge of the received signal as follows. Signal generator 56
When the input level at point A, which is the input terminal of
The output of NAND element N3 is at H level. Therefore, the output of the signal output terminal 7b of the NAND element N4 becomes L level. When the input level at point A is reversed to L level, input 3 of NAND element N3
a becomes H level immediately. On the other hand, input N3
Until a certain amount of charge is accumulated in the capacitor C1 of the time constant circuit between b and the inverting element NA,
The input of the inverting element NB remains at L level. Therefore, the output of the inverting element NB remains high until a certain amount of charge is accumulated in the capacitor C1.
level, so the input N3 of NAND element N3
b is maintained at H level. That period,
NAND element N3 has both inputs N3a and N3b
Since it becomes H level, it outputs L level.
Therefore, the signal output terminal 7 of NAND element N4
The output of b becomes H level, and an energizing signal is generated. As charging in capacitor C1 progresses and input N3b becomes L level, the output of NAND element N3 is inverted to H level.
The output level of the signal output terminal 7b of the NAND element N4 becomes L level, and the energizing signal disappears. In other words, even at the time of falling, the energizing signal is generated for a short fixed period determined by the time constant circuit. On the other hand, as soon as the input level at point A shifts to the L level, the input N1a of the NAND element N1 becomes the L level, so the output of the NAND element N1 becomes the H level regardless of the current state of the input N1b. Therefore, the output of the output terminal 7a of the NAND element N2 remains at the L level.

A switch control section 57 including a two-winding latching relay R is provided downstream of the signal generating section 56, and a contact 61a of the latching relay R is provided.
serves as a switch section 61. relay coil
As shown in the figure, Ra and Rb are transistor Q
The contact 61a is kept closed when the transistor Q2 is conductive even for a short time, and the contact 61a is kept open when the transistor Q3 is conductive even for a short time. The base of transistor Q2 is connected to resistor R
Since the base of the transistor Q3 is connected to the output terminal 7b of the NAND element N4 through the resistor R6, the energizing signal is input to the base of the transistor Q2. When the energizing signal is input to the base of the transistor Q3, the transistor Q2 becomes conductive and the contact 61a is kept open during that period. That will happen. Contact 61a
The period during which current flows through the transistors Q2 and Q3 due to the reversal of opening and closing of the transistors is only during the generation period of the energizing signal. AC power supply 58 is connected to DC power supply 60 via transformer TS. DC power supply 60
As shown in the figure, current is supplied to each necessary location. In this wireless switch receiver, current flows from the DC power supply 60 only when an energizing signal is generated at a very short time interval when the open/closed state of the switch section 61 is reversed, and thereafter, to maintain the open/closed state. does not require any current. In other words, the energizing operation is performed only for a very short time to reverse the open/closed state of the switch section 61, which requires a large amount of current. Therefore, the transformer TS has a capacity of
A very small one will suffice.

This receiving circuit incorporates an emergency switch 80 that can be manually operated from the outside, separate from the signal from the receiving circuit. When the contact of the emergency switch 80 is closed, a positive charge is applied to the base of the transistor Q2, making the transistor Q2 conductive and immediately closing the contact 61a.

The position of this emergency switch is not limited to this position. For example, if the capacity of the contact allows, it may be provided at the position shown by the chain line in FIG. If it is provided in this position, the operation reliability is high.Furthermore, the switch control section 57 may be constructed as a circuit as shown in FIG. 7, and an emergency switch may be incorporated therein.

The operation of this circuit will be explained. In the figure, S is a set of contacts of the latching relay R, and when a current flows through the relay coil Ra and the contact 61a is closed,
Contact S1 and contact S2 are connected, and the relay coil
When current flows through Rb and contact 61a is opened,
Contacts S1 and S3 are connected. Therefore, when contact S1 and contact S2 are connected, capacitor C3 is charged and contact S1
When the contact S3 is connected, the capacitor C2 is charged. Since it is configured like this, when the emergency switch 80 is pressed and the contacts are closed, current flows from the charged capacitor to the relay coil, and the contacts 61 of the switch section 61 are
A can be opened and closed freely. Furthermore, since the capacitor is charged with power for operating the latching relay R, the latching relay R can be operated even if the current flowing through the switch control section is small.
