[0002]

2. Description of the Related Art FIG. 5 shows a conventional example of a remote monitoring control system. The data of the transmission signal Vs by time division multiplexing, which is transmitted from the transmission unit 1 of this remote monitoring and control system to the pair of signal lines 2, has a start pulse ST indicating a signal transmission start and a signal mode as shown in FIG. 6A. Mode data MD shown, 8-bit address data AD for accessing each of the terminals 3, 4, 5, 6, 7; control data CD for controlling the lighting load L; and checksum data C
S and a reply waiting period data WT for setting a reply period. These data are transmitted from the transmission unit 1 to a multi-pole (± 24V) baseband time division multiplexed transmission signal Vs as shown in FIG. 6B. To be converted. At this time, signals other than the reply waiting period data WT are pulse-width modulated signals, and the reply waiting period data WT is transmitted as a long pulse signal having a constant time width.

Terminals 3 to 7 connected to the signal line 2
Then, when the content of the address data D of the transmission signal Vs received via the signal line 2 and the preset own address match, the control data CD of the transmission signal Vs is fetched and the transmission signal Vs Return waiting period data W
In synchronization with T, monitoring (operation) data is sent back to the transmission unit 1 as a current mode return signal obtained by connecting an appropriate low resistance between the signal lines 2.

The on / off operation terminal 3 of the operation terminals is provided with operation switches SW _{1 to} SW ₄ corresponding to, for example, four illumination loads L. On the other hand, the dimming operation terminal 3 stops the dimming operation switch SU for increasing dimming and the dimming down operation switch SD for decreasing dimming and the dimming control operation during up or down. At least a dimming stop operation switch SS is provided.

Of the load control terminals, the ON / OFF control terminal 5 can individually control, for example, four lighting loads L, and the control data CD sent from the transmission unit 1 is used. Based on this, each lighting load L is turned on or off. Further, the terminal 6 for dimming control has a built-in dimmer that dims the lighting load La such as an incandescent lamp by phase control, and the transmission unit 1 sends the dimming-up control data CD. Then, the control data for dimming down or dimming down is controlled until the dimming stop or dimming down control data CD is sent. When a CD is sent, the dimmer is controlled so that the dimming stop or the dimming up control data is sent from the current dimming state until the dimming control data CD is sent. There is.

When each of the terminals 3, 4, 7 is operated or the data by the optical wireless signal is received, the interrupt signal Vi shown in FIG. 6C is transmitted by the timing of the start pulse ST of the transmission signal Vs. Then, the transmission unit 1 is notified of the operation or the data reception.

At this time, the transmission unit 1 does not know which of the terminals 3, 4, and 7 is used, and therefore transmits the transmission signal Vs in the address search mode.

Is received, the control data CD for controlling the state of the lighting load L targeted by the operation data is transmitted to turn it on in the off state and to turn it off in the on state.

Further, if the operation data is from the dimming operation terminal device 6 or the optical wireless relay terminal device 7, up,
It is determined whether it is down or stop, and the control data CD based on the determination result is transmitted.

When the setting address data is subsequently transmitted by the optical wireless signal from the optical wireless signal transmitter (not shown), the optical wireless signal processing circuit 17 which has received the setting address data through the optical setting receiving unit 22 causes the EEP to operate.
Address data is written in the address setting area of the ROM 19. At the same time, the certainty signal indicating that the setting address data has been received is transmitted through the optical setting transmission unit 23 as an optical wireless signal. The confirmation signal is received by the optical wireless signal transmitter (not shown) and displayed on the display unit provided in the optical wireless signal transmitter (not shown), and the user sets the address by this display. You will be able to confirm that.

The address data written in the EEPROM 19 is then used as the unique address of the terminal. When it is desired to confirm the address set in the EEPROM 19, a confirmation command may be transmitted from the optical wireless signal transmitter (not shown) to the terminal device 4 by an optical wireless signal. In this case, the optical wireless signal processing circuit 17 which has received the confirmation command through the optical setting receiving section 22 reads the address data from the EEPROM 19, and transmits the address data through the optical setting transmitting section 23 as an optical wireless signal. The optical wireless signal having this address data is received by the optical wireless signal transmitter (not shown), demodulated, and displayed on the display unit provided in the optical wireless signal transmitter (not shown). The user can confirm the set address by this display.
