In this conventional wireless dimming system, when a continuous dimming wireless signal is detected as a signal rise and data, and then transmitted as a continuous signal, it is determined as continuous data and the signal is interrupted. The light control is stopped at. It is a so-called continuous data retrigger operation. When this method is transferred to the data exchange with the remote control system of time division multiplex transmission, while the continuous signal is being received by the remote control system, the operation of other load control etc. as the system is greatly affected. Become. That is, there is a problem that the data processing of the entire system is limited because the received data processing of the wireless signal is continuous.

A series circuit of a contact 14a of a relay driven by the load interface 14 and a load 15 is connected in parallel to the power supply 16.

Then, the optical wireless signal transmitted from the transmitter 1 is received by the nearest satellite receiver 2, only the signal of the frequency determined by the tuning circuit 4 is detected, and the baseband converter 5 converts it into a baseband signal. It is converted and transmitted to each of the receivers 7 and 11 through the wired signal line 6. If the mode data SI of the transmission code selects the individual operation, the system receiver 7 does not respond and the individual receiver 11 is the target. The address of the baseband signal is checked at each individual receiver 11, and if it matches the set address, the load interface 14 drives the relay based on the control data to load the load.

In the system operation, the transmission code from the transmitter 1 is received by the satellite receiver 2, and the baseband signal transmitted from the satellite receiver 2 is converted into a binary parallel signal. 9 is input. The input address and control data are stored in the storage unit 20, and the stored address is regarded by the address setting unit 22 as the address of the terminal device viewed from the central control unit 31. In this embodiment, up to four pieces of address data transmitted from each transmitter 1 are sequentially stored. When four pieces of address data are stored, they are canceled by the canceling means 21, and the address and control data of the next transmitter 1 are stored. Address setting section
In 22, since the address stored in the storage unit 20 is used as the address of the terminal device (system receiver 7) as described above, the address setting unit 22 is used as the terminal device when the system receiver 7 is viewed from the side of the central control device 31. By accessing the address set in, remote control of normal time division multiplex transmission is performed. Therefore, the control data from the transmitter 1 is stored in the system interface 9, and when the system receiver 7 is accessed, the control data is returned to the central control unit 31 within the return waiting period of the transmission signal, and the central control is performed.

FIG. 1 is a block diagram showing the gist of the present invention in which a remote control system for time division multiplex transmission and a wireless remote dimming system including an oscillator 1, a satellite receiver 2 and a system receiver 7 are combined. Is. On the signal line 34 from the central control device 31, the system receiver 7 for receiving the wireless signal from the transmitter 1, the terminal device 32 as a wall switch function, the terminal device 33 for load control, and the lighting load adjustment device. The terminal device 33a for optical control is connected. Here, the present invention is
When dimming the lighting load, interface with the system receiver 7 and the remote control system by handshaking, and start receiving the dimming data of the wireless signal from the transmitter 1 and after receiving the continuous dimming data. It is characterized in that the handshake process is performed only at the time of stopping. As shown in FIG. 1, the transmitter 1 has a switch 1a for turning on / off a lighting load, a switch 1b for increasing dimming,
A dimming down switch 1c and the like are provided. The lighting load on / off data and dimming data are created by the signal processor 18 of the transmitter 1.

Then, the switch state of the transmitter 1 and the wireless signal encoding the individual address are detected by the receiving unit 8 of the system receiver 7, and the data is exchanged by the handshake with the system interface 9 by the strobe signal and the ready signal. . As described above, the address of the system receiver 7 stores the address of the wireless signal of the transmitter 1 and becomes the address of the system receiver 7,
It will be accessed from the central control unit 31. FIG. 2A shows a dimming processing flow in the system mode,
FIG. 6B shows a data code of the light control data. The lower 4 bits of the data code indicate the dimming mode,
The upper 4 bits indicate on / off, up, down, and stop. If the lower 4 bits of the data code received by the receiver 8 of the system receiver 7 are, for example, 0101 (“5”), it indicates the dimming mode of the lighting load. The system is a normal system process. Next, when the lower 4 bits of the data code is 5 and the upper 4 bits are "4" or "2", the up or down dimming mode is set. If the upper 4 bits are "8", this is an ON / OFF signal of the lighting load, and the process proceeds to normal system processing. Add "45" to the data code.
If "H" or "25H" is output and continuous reception of this output is stopped, "15H" is added to the data code.
Is output to shift to normal system processing.

In the continuous dimming of the system mode dimming process, the system interface 9 is a receiving interface process for performing a handshake with the remote control system side at two points, that is, a continuous start point and a continuous stop point of the data code. The switch state (ON / OFF UP DOWN) of the transmitter 1,
Dimming type code (D ₃ ~D _0: Max5) data is handshake at the start of a remote control system, a dimming type code stop code (STOP bit) is a handshake at the end. In addition, the receiving unit 8 determines whether it is continuous or stopped.
The operation is performed during the pause time of the wireless signal from the transmitter 1. For example, when the rest time is 60 mS or more, it is determined to be stopped.

[Advantages of the Invention] As described above, the present invention connects the central control device and a plurality of monitoring terminals or control terminals having unique addresses by a signal line, and the central control device controls each terminal.

Wireless remote dimming that takes in as monitoring data, transmits this monitoring data as control data for lighting load control to the control terminal in a time-division manner, and dims the lighting load. A handshake with the remote control system side only at the control system, which is a reception unit that receives a wireless signal from a transmitter, a start point of receiving the dimming data of the wireless signal, and a stop point after receiving the continuous dimming data. In addition, since the above receiver is configured with a system interface that determines whether continuous dimming or stop at the receiving unit is based on the pause time of the wireless signal from the transmitter, Handshaking with the remote control system side is performed only at two points: when the signal dimming data is received and when it is stopped after receiving the continuous dimming data, the data is exchanged between the receiver and the remote control system by a wireless signal. When the lighting load is dimmed, there are only two points: the start point of receiving the dimming data of It is possible to reduce the influence on other system operations, and it is possible to easily determine the stop point because the pause time of the wireless signal determines whether the continuous dimming or the stop in the receiving section is performed. With this method, it is possible to introduce optical wireless dimming into the influence control system.
