ようになっている。The external interface terminal 8 is a terminal that performs data transmission with the external control device 8a, and the pattern setting terminal 9 transmits pattern control data input from the data input section 9a to the central control device 1. This is the terminal device for the transfer. The monitoring terminal 2 and the control terminal 3 installed in the distribution board 6 or relay control panel 6a have the dimensions agreed upon in the distribution board, and their control output enables the remote control relay for load control. (A latching relay that can be turned on and off using a hand switch) 5 is controlled.
ところで上記制御用端末器３としては負荷をオンオフさ
せる端末器以外に、照明負荷りを調光するための調光用
端末器３ａがある。By the way, as the control terminal device 3, in addition to the terminal device for turning on and off the load, there is also a dimming terminal device 3a for dimming the lighting load.
この調光用端末器３ａは従来第５図に示すように構成さ
れており、この従来例では中央制御装置１から制御デー

調光回路１２に設けであるトライアックのような位相制
御素子１３をオンさせ、照明負荷りを位相制御するよう
になっている。This dimming terminal 3a is conventionally configured as shown in FIG. 5, and in this conventional example, the control data from the central controller 1 is expressed as 100%, with the maximum brightness in the phase controllable range being 100%. When the shown dimming data is transmitted and received by the signal transmitting/receiving section 10, a trigger signal is generated from the trigger generation circuit 11 at a phase angle corresponding to the dimming data,
A phase control element 13 such as a triac provided in the dimming circuit 12 is turned on to control the phase of the lighting load.
ここで例えば照明負荷りが白熱電球であれば、商用電源
電圧の変動やノイズ等によるちらつきを考慮して位相制
御可能角は一般に約３５度〜約１４５度とされており、
従って位相角が約３５度の時が最大の明るさ（１００％
）で、約１４５度のときが調光レベルが最小（０％）と
考えられる。For example, if the lighting load is an incandescent bulb, the phase controllable angle is generally about 35 degrees to about 145 degrees, taking into account flickering due to fluctuations in commercial power supply voltage and noise.
Therefore, the maximum brightness (100%) is when the phase angle is approximately 35 degrees.
), the dimming level is considered to be at its minimum (0%) when the temperature is about 145 degrees.
蛍光灯の場合には位相制御可能角は蛍光灯の種類によっ
てまちまちであるが、可能な範囲の最大値を調光レベル
１００％とし、最小値を調光レベルＯ％とするのは白熱
と同じである。In the case of fluorescent lamps, the phase controllable angle varies depending on the type of fluorescent lamp, but it is the same as incandescent that the maximum value of the possible range is the dimming level 100% and the minimum value is the dimming level 0%. It is.

合を夫々示す。By the way, when performing dimming on the dimming terminal 3a''i' in FIG. 5, first the power supply cycle detection circuit 14 detects the cycle of the commercial power supply used and determines from which power supply voltage zero cross point a predetermined dimming level. The time to reach the phase angle corresponding to 145 degrees is determined, and a trigger signal is generated based on that time.However, if the frequency of the commercial power supply used is 50 Hz, the time to reach the phase angle of 145 degrees is 8. 1m5ec, phase angle 35
The time to reach the phase angle of 145 degrees is 1.9 m5ec, but when the frequency is 60 Hz, the time to reach the phase angle of 145 degrees is 6.
7m5ec5, time to phase angle 35 degrees is 1.6m5e
c. Therefore, in the conventional example, the power supply frequency detection circuit 15
The power supply frequency was detected at , and the generation time t of the trigger signal shown in FIG. 6 was switched depending on the frequency. FIG. 7 shows the relationship between the phase angle and the time from the zero cross point, where A shows the case where the frequency is 50 Hz, and Fig. 7 shows the case where the frequency is 60 Hz.

た。[Problem M to be solved by the invention] By the way, in the above conventional example, it is necessary to provide the power frequency detection circuit 15 in each dimming terminal 3a, and in addition, the dimming level simply expressed as a percentage based on the brightness. data is transmitted from the central control unit 1, so if it is compatible with incandescent lamps, it cannot be used with lighting loads such as fluorescent lamps, which have different dimming ranges, and illuminance and phase The relationship between the angle and the angle is the curve a in Figure 8 [p□e−i=E”/
