After that, the lighting control data is transmitted from the central monitoring device 11 to the control terminal 21 based on the rewritten lighting control data by the operation of the monitoring terminal 31, and the lighting of the lighting fixture is controlled.

As described above, according to the lighting control system of the present invention, by connecting the external setting device 51 to the monitoring terminal device 31 for monitoring the lighting state of the lighting device provided in the vicinity where the lighting devices La to Lc are installed, The reading of the lighting control data of each of the lighting devices La to Ld provided in the central monitoring device 11 installed at a remote location from the lighting devices La to Ld or the monitoring terminal device 31 and the modification of the read lighting control data are performed. It has become possible. In particular, when performing dimming control, depending on the actual lighting condition of the place where dimming is required,
This has the advantage that the dimming degree can be set and the lighting control data can be changed and corrected in a short time.

In the lighting control system of the present invention, the transmission / reception of the lighting control data between the central monitoring device 11, the control terminal 21, and the monitoring terminal 31 uses an example in which a signal transmission line 61 is provided. As described above, the transmission and reception of the lighting control data may be performed by transmitting the lighting control data to the power supply line of the driving power supplied from the central monitoring device 11 to the control terminal 21 and the monitoring terminal 31. Thereby, the labor of the transmission line can be saved.

The transmission and reception of the lighting control data between the monitoring terminal device 31 and the external setting device 51 are performed via the connector 36 and the connection connector 58. However, the monitoring terminal device 31 and the external setting device 51 are connected. It is also possible to provide a wireless or infrared data transmission / reception function. Non-contact type monitoring terminal 3 using such wireless or infrared rays
When the data transfer method between the external setting device 51 and the external setting device 51 is used, the lighting control data of the central monitoring device 11 can be rewritten by the external setting device 51 without being restricted by the installation location of the monitoring terminal device 31.

[0078]

According to the lighting control system of the first aspect of the present invention,
The external setting device is connected to the monitoring terminal device, the lighting control data set in the central monitoring device is read out and displayed on the external setting device, and based on the lighting control data displayed on the external setting device, the lighting fixture is used. The lighting conditions can be set while checking the lighting condition of the lighting fixtures near the location where the lighting fixtures are installed, and the lighting control can be performed in a short time and suited to the place where the lighting fixtures are installed It has the following effects.

The lighting control system according to the second aspect of the present invention is the lighting control system according to the first aspect, wherein the monitoring terminal device and the external setting device can transmit and receive lighting control data and the like without contact. It is possible to confirm, change, and correct the lighting control data of the lighting fixture installed at a position distant from the monitoring terminal, and has an effect of enabling optimal lighting control of the installation location of the lighting fixture.
