There are also provided a plurality of satellite receivers 2 for receiving the.
A unique address is set for each of the transmitters 1, and, for example, control data for on / off control of the lighting equipment is transmitted together with the address data as an optical wireless signal as shown in FIG. 8 (a) as a transmission code. . As shown in FIG. 9, the transmission code of this optical wireless signal is composed of address data AD and control data CD. Here, the mode data SI before the address data AD is used for other system operations such as a remote control device for time division multiplex transmission,
Alternatively, it is a mode for selecting whether to perform an individual operation in the wireless system. As shown in FIG. 6, the transmitter 1 specifically includes an address setting unit 17 that allows an address to be set arbitrarily, a signal processing unit 18 that creates a transmission code corresponding to each operation switch 1a to 1d, and a signal processing unit. It is composed of a light emitting unit 19 and the like including a light emitting diode or the like that transmits the code from the unit 18 as an optical wireless signal.

On the other hand, a satellite receiver 2 that receives an optical wireless signal
Is configured as follows. That is, as shown in FIG. 7, the optical wireless signal from the transmitter 1 is received and the PIN is received.
FIG. 8B shows an optical receiver 3 including a photoelectric element such as a die-dode, a tuning circuit 4 having a tuning function for detecting a carrier wave of an output signal from the optical receiver 3, and an output of the tuning circuit 4. The satellite receiver 2 is composed of the baseband conversion unit 5 and the like for converting such a baseband signal.

The baseband signal from the satellite receiver 2 is sent out on a dedicated signal line 6 and transmitted to a system receiver 7 and a plurality of individual receivers 11 connected to the signal line 6.
The system receiver 7 receives the baseband signals from the satellite receiver 2 all together, and as shown in FIG.
A receiving unit 8 for receiving a baseband signal, a setting unit 10 for selecting whether the operation is system or individual as described above, and address data and control for converting the baseband signal into a binary parallel signal by the receiving unit 8. It is composed of a system interface 9 for inputting data. This system interface 9 is the signal line 34 of the multiplex transmission control system.
And is processed according to the procedure on the side of the central control device 31. Only the signal format set by the receiving unit 8 of the system receiver 7 is extracted from the base band signal, the setting unit 10 determines whether the system operation or the individual operation is performed, and the received address data and control data are received from the receiving unit 8. Output to the system interface 9.

As shown in FIG. 7, the individual receiver 11 includes a receiving unit 12 that receives a baseband signal from the satellite receiver 2, an address setting unit 13 that sets a unique address for each,
It is composed of a load interface 14 for driving a load control relay and the like according to control data. That is, in this individual receiver 11, the baseband signal and each individual receiver 11

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.

The operation when the operation switch 1a of the transmitter 1 is operated will be described. When the operation switch 1a is operated, the data corresponding to the operation switch 1a is created in the signal processing unit 18, and the data code of the data is sent from the light emitting unit 19 as a wireless signal. The optical wireless signal transmitted from the transmitter 1 is received by the nearest satellite receiver 2 and only the signal of the frequency determined by the tuning circuit 4 is detected,
It is converted into a baseband signal by the baseband converter 5 and is transmitted to each of the receivers 7 and 11 through a wired signal line 6. If the mode data SI of the transmission code selects individual operation,
The system receiver 7 does not respond and the individual receiver 11 is targeted. The address of the baseband signal is compared in each individual receiver 11, and if it matches the set address, the load interface 14 drives the relay based on the control data to control the load 15. Here, if the mode data SI of the optical wireless signal from the transmitter 1 selects the system operation, the system receiver 7 responds. That is, the address and control data obtained by converting the baseband signal into a binary parallel signal are transferred to the system interface 9
And is processed according to the procedure of the remote control system side of the multiplex transmission.

Next, the gist of the present invention will be described. As shown in FIG. 1, the oscillator 1 is provided with, for example, four operation switches 1a to 1d. FIG. 1 (b) shows the switches K ₀ to
The IC 20 that generates a preset data code depending on the ON state of K ₃ and the operation switches 1a to 1d are shown. The switches K _{0 to} K ₃ and the operation switches 1a to 1d have a matrix configuration. In the case of FIG. 1, K ₀ and 1a, K ₁ and 1b, K ₂ and 1
c, K ₃ and 1d correspond respectively. Further, the oscillator 1 is set in advance so that four operation switches 1a to 1d are arranged. Here, as shown in FIG. 2, the code generated by the switch K ₀ (control data) is, for example, 4-bit 0001, the code generated by the switch K ₁ is 0010, and the code generated by the switch K _{2 is}
The code generated by is set to 0100, and the code generated by switch K ₃ is set to 1000. Therefore, when provided with four operating switches 1a~1d of the transmitter 1, keep the switches K ₀ ~K ₃ to the ON state. When the operation switch 1a is operated, a code generated by K ₀ is generated, and when the operation switch 1b is operated, K ₁
When the operation switch 1c is operated, the generation code by K ₂ is generated, and when the operation switch 1d is operated, the generation code by K ₃ is generated. The IC 20 and the switches K _{0 to} K ₃ constitute a data generating means.

Then, if you three implement operation switch 1a~1c configured to generate data to three of the switch K ₀ ~K ₃ to the ON state as follows. In this case, as an example, the case where the switches K ₀ , K ₂ , and K ₃ are on and the case where the switches K ₁ , K ₂ , and K ₃ are on will be described. First, the case where the switches K ₀ , K ₂ and K ₃ are turned on will be described. In this case, as shown in FIG. 3 (a), a code (0001) is generated by the switch K ₀ when four operation switches are mounted at the position of the operation switch 1a, and four operation switches are mounted at the position of the operation switch 1b. Time switch
A code (0100) is generated by K ₂ , and the operation switch 1c
The code (1000) generated by the switch K ₃ when the four operation switches are mounted is generated at the position. Next, a case where the switches K ₁ , K ₂ and K ₃ are turned on will be described. As shown in FIG. 3 (b), the code generated by the switch K ₁ when four operation switches are mounted at the position of the operation switch 1a (00
10) occurs, the operation switch 4 is placed at the position of the operation switch 1b.
A code (0100) is generated by the switch K ₂ when one switch is mounted, and a code (1000) is generated by the switch K ₃ when four control switches are mounted at the position of the control switch 1c.

Next, when two operation switches 1b and 1c are mounted, set as follows. When the switches K ₀ and K ₃ are turned on, as shown in FIG. 4 (a), the code (0001) generated by the switch K ₀ when the four operation switches are mounted is generated at the position of the operation switch 1b, and the operation is performed. A code (1000) is generated by the switch K ₃ when four operation switches are mounted at the position of the switch 1c. Next, when the switches K ₂ and K ₃ are turned on,
As shown in the figure (b), the code generated by the switch K ₂ when four operation switches are mounted at the position of the operation switch 1b (010
0) occurs and the operation switch 4 is placed at the position of the operation switch 1c.
Code (1000) is generated by the switch K ₃ at the time of mounting. When the switches K ₁ and K ₂ are turned on, a code generated by the switch K ₁ when four operation switches are mounted at the position of the operation switch 1b as shown in FIG. 4 (c) (0010)
Occurs, and the generation code (0100) of the switch K ₂ when four operation switches are mounted is generated at the position of the operation switch 1c.

Furthermore, when one operation switch 1b is mounted, the settings are as follows. When the switch K ₀ is turned on, as shown in FIG. 5 (a), when four operation switches are mounted at the position of the operation switch 1b, the code (0001) of the switch K ₀ is generated and the switch K ₁ is turned on. In that case, a code (0010) is generated by the switch K ₁ when four operation switches are mounted at the position of the operation switch 1b. If the switch K ₂ on, FIG. 5 the position on the operation switch 1b as shown in (c) switch 4 at the time of mounting the switch K ₃ by generating code (0100) is generated, turning on the switch K ₃ As shown in FIG. 5 (d), the code generated by switch K ₃ when four operation switches are mounted at the position of operation switch 1b (1000)
Is generated.

That is, by appropriately setting the number of switches K _{0 to} K ₃ and the on / off state according to the number of operation switches, it is possible to generate preset arbitrary data by operating the operation switches. As described above, in the case of 4 Tsugaon switch K ₀ ~K _3, to generate data corresponding to the switch K ₀ ~K ₃ to a position where the operation switch 1a~1d are arranged. If _three of the switches K _{0 to} K ₃ are on,
Switches that are turned on in the positions of operation switches 1a to 1c
Generates data corresponding to K _{0 to} K ₃ . However, the operation switches 1a → 1c are associated with the switches K ₀ → K ₃ in ascending order. In the case of 2 Tsugaon the switches K ₀ ~K _3, the operation switch 1b, and generates data corresponding to the switch K ₀ ~K ₃ are turned on at the position of 1c. Further, when one of the switches K _{0 to} K ₃ is on, the data corresponding to the switches K _{0 to} K ₃ which are on at the position of the operation switch 1b is generated.

[Effects of the Invention] As described above, the present invention arbitrarily sets predetermined data according to the number of operation switches arranged at an arbitrary physical position where a predetermined number of operation switches are arranged. Since it is provided with a data generating means for generating the data, the data generating means determines a predetermined number according to the number of operation switches arranged at an arbitrary physical position where a predetermined number of operation switches are arranged. The generated data can be generated arbitrarily.Therefore, the number of operation switches and the data generated for the operation switches can be set arbitrarily, and it is not possible to design cases etc. individually as in the past. Because there is no, it is possible to reduce costs, and
The effect is that the user can easily change the correspondence between the operation switch and the data.
