ようになつていた。 Figure 2 shows the circuit configuration of a conventional receiver 2 used in such a system. In this conventional circuit, a transmission signal (for example, a bipolar signal) on a transmission line 3 is connected to a DC power supply. A section 4 performs full-wave rectification and smoothing to obtain a predetermined direct current, thereby obtaining power for the signal processing circuit 5. The signal processing circuit 5 is composed of a logic processing circuit such as a one-chip microcomputer, for example, and full-wave rectifies the commercial power supply AC connected to the dimmer 6 using a diode bridge DB, and uses its pulsating output to drive a transistor Tr. Turn on and off commercial power AC
Using the zero-cross detection signal from the zero-cross detection section 7 as a reference timing, a trigger pulse with a phase based on the dimming control data from the main unit 1 is sent to both the dimmers 6 via the pulse transformer PT. It is designed to be applied to a tropic three-terminal thyristor 8. Furthermore, data is transmitted as a return signal to the master unit 1 during the above-mentioned return waiting period based on inputs from the up switch SW 1 and down switch SW 2 for dimming control.

があつた。 By the way, in this type of system, the location where the main unit 1 is installed is far from the location where the receiver 2 is installed, and the breakers for each commercial power AC line are often separate, so the commercial power AC line on the receiver 2 side Even if the line breaker is tripped, the signal processing circuit 5 of the receiver 2 receives power from the transmission line 3, so the transmission signal is correctly transmitted from the parent device 1.
Moreover, even if the system is determined to be normal in the main device 1 because the correct return can be performed, there is a problem in that the lamp L on the dimmer 6 side is not actually lit.

The present invention has been made in view of the above-mentioned drawbacks.
The purpose of this is to collect data from the receiver on abnormal conditions such as failures in the zero cross detection section of the commercial power supply connected to the receiver's dimmer, or cases where the commercial power line breaker is tripped. The present invention provides a receiver for a remote control dimming system that can transmit data to a device.

Switches SW 1 and SW 2 are connected to the signal processing circuit 5,
This differs from the conventional example in that, in addition to the down monitoring inputs UP and DWN, a failure monitoring input is provided to input the rectified and smoothed signal of the zero cross detection signal smoothing section 9.

させないのである。(Operation) First, during normal operation, it is the same as the conventional example shown in FIG. In other words, during this normal operation, the zero cross detection signal shown in FIG. 4b corresponding to the zero cross of the commercial power supply AC shown in FIG. Based on this reference timing and the received dimming control data, the signal processing circuit 5 sends a trigger pulse of a predetermined phase from the trigger output terminal to the gate of the bidirectional three-terminal thyristor Q1 through a pulse transformer PT. The phase of the lamp L is controlled. On the other hand, the signal from the zero-cross detection signal smoothing section 9 that rectifies and smoothes the zero-cross detection signal is an "H" level signal as shown in FIG. This data is returned to the main unit 1 along with other monitoring input bit data during the return waiting period. By receiving this monitoring data, the parent device 1 determines that the commercial power supply AC and zero cross detection section 7 of the receiver are normal, and does not operate, for example, a failure alarm means (not shown).

フが行なえるようにしてもよい。 Next, when the commercial power AC of the receiver 2 is cut off by a breaker or other cause, or when a failure occurs in the zero cross detection section 7, the zero cross detection signal is not generated as shown in the latter half of Figure 4b. , the output of the zero cross detection signal smoothing section 9 becomes "L" level, and the return data of the monitoring input to the master device 1 becomes "L" level. This means that you can take measures such as notifying others. Furthermore, since the zero cross detection signal smoothing section 9 has a differentiating circuit consisting of a capacitor C and a resistor R at its input to detect the change point of the input, the output of the zero cross detection section 7 becomes "H" level. Even if a failure occurs, the output of the zero-cross detection signal smoothing section 9 goes to the "L" level, and the failure can be detected in the manner described above. Furthermore, considering the case where only the zero cross detection section 7 is out of order, a relay control signal is sent from the main unit 1 to the receiver 2 so as to short-circuit the bidirectional three-terminal thyristor 8 of the dimmer 6 when a failure is detected. The lamp L may be turned on and off even in the event of a failure.

The present invention includes a zero cross detection signal detection means for detecting a change in the zero cross detection signal output from the zero cross detection section, and output data of the detection means taken in from the monitoring input is sent to the parent device at a predetermined timing. Since it is equipped with a signal processing circuit that returns the signal, the parent device can take measures such as cutting off the commercial power supply to the receiver side, detecting a failure in the zero cross detection section, and generating an alarm. Since the amount of change in the cross detection signal is detected, any trouble in which the zero cross detection signal is fixed to "H" or "L" can be detected, and high reliability can be obtained.
