いた。 2. Description of the Related Art Conventionally, remote control devices are known that control the phase of a load such as a lighting device connected to each terminal device using a control signal from a main operation panel. In such a remote control device, an address signal, a control signal, etc. are transmitted from the main operation panel to a terminal device through a dedicated two-wire transmission line, and the terminal device corresponding to the address signal determines the phase of the load based on the control signal. Control takes place. In this case, the synchronization with the commercial power supply required for phase control is performed using a synchronization signal created by detecting the zero-crossing point of the commercial power supply by a synchronization circuit including a zero-crossing detection circuit installed in each terminal. I was getting used to it.

低下するという欠点があつた。 However, in the conventional type described above, since each terminal device detects the zero-crossing point from the commercial power supply and creates a synchronization signal, the phase of the synchronization signal fluctuates due to noise superimposed on the commercial power supply, causing the lighting load to change. There were disadvantages such as flickering and the inability to perform precise phase control. Additionally, in order to prevent the phase of the synchronization signal from fluctuating due to noise superimposed on the commercial power supply, it is necessary to provide a complicated synchronization circuit in each terminal device, which increases the complexity of the terminal device and increases the cost. There was this inconvenience. especially,
If a wide range of noise such as elevator noise is superimposed on the commercial power supply, the zero-crossing point will fluctuate greatly, and in order to deal with such fluctuations, each terminal becomes extremely complex, expensive, and unreliable. The disadvantage was that it decreased.

ことはない。 When controlling the phase of the load 3 in a terminal device, conventionally, synchronization with the commercial power source is achieved by determining the zero-crossing point of the commercial power source sent through the power line 5 using a circuit provided inside the terminal device. It was clear. Since such conventional methods have various disadvantages as mentioned above, in the present invention, for example, as shown in FIG. A synchronizing signal S indicating the position of the zero cross point Z of the power supply is inserted. A data signal D including an address signal, a control signal, etc. is arranged between each synchronization signal S. By transmitting such a transmission signal from the main operation panel 1 to each terminal device 2-1, 2-2,..., there is no need to detect the zero-crossing point of the commercial power supply in each terminal device, and therefore the zero-crossing detection circuit etc., and the configuration is simplified. In each terminal device 2-1, 2-2,..., it is only necessary to provide a synchronization separation circuit or the like that separates the synchronization signal S from the transmission signal transmitted via the transmission line 4. Phase control of the load 3 can be performed using the separated synchronization signal S. In this case, a zero-cross detection circuit is provided in the main operation panel 1 to detect the zero-cross point of the commercial power supply from the power line 5, create a synchronization signal, and insert it into the transmission signal. Therefore, even if noise is superimposed on the power line 5, each terminal does not detect the zero-crossing point of the commercial power from the power line, so the main operation panel 1 and each terminal 2-1, 2-2 ,... will not be disrupted.

During this period, the power signal P for the terminal device is transmitted together with the data signal D.
It is also possible to insert in a time-division manner. For example, by setting the voltage level of the power signal P higher than the high-level voltage of the data signal D, it is possible to selectively extract only the portion of the power signal P in the terminal, and the extracted By supplying the power signal portion P to a smoothing circuit or the like, it can be converted into a DC voltage and power for the terminal device can be obtained. Alternatively, it is also possible to obtain a DC output by directly inputting a transmission signal as shown in FIG. 3 to a smoothing circuit or the like.

Since the signal is transmitted to each terminal device in a time-division manner, the synchronization of each terminal device is not disturbed by noise superimposed on the power supply line, and precise phase control can be performed. Therefore, even when a lighting device or the like is connected as a load to each terminal device, flickering caused by noise superimposed on the commercial power source can be prevented. Furthermore, since there is no need to provide a zero-cross detection circuit or the like for each terminal, the configuration of each terminal is simplified, reliability is improved, and the price can be reduced.
