DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an automobile electrical component control system according to the present invention, and parts equivalent to those in FIG. 2 are designated by the same reference numerals. In the figure, the system of this embodiment has a configuration in which a transmitter and a plurality of receivers are provided, and the transmitted data is sent superimposed on the power supply, thereby reducing the number of wiring lines. That is, 25 in the figure is a transmitter, and 211
~216 is the receiver. Each receiver is assigned an address.

Among the receivers, a receiver 211 is provided to control on/off of the right blinkers 11 and 12. Similarly, a receiver 212 is provided to turn on and off the left turn indicators 15 and 16, and a receiver 213 is provided to turn on and off the headlamp 13 and combination tail lamp 14, respectively.

Further, the receiver 214 is connected to the headlamp 13.
In order to operate the high beam, the receiver 215 is provided to turn on the brake lamp of the combination tail lamp 14. A receiver 216 is provided to operate the phone 20. Note that 24 is an adder.

In such a configuration, if an address is set in the address setter in the transmitter 25, the electrical component can be operated by the receiver corresponding to the address.

That is, when operating each electrical component, first the main switch 22 is operated to turn it on. By turning on the main switch 22, power can be supplied from the battery 17 to each electrical component. Next, the adder 24 supplies command data for blinking the right blinkers 11 and 12 from the transmitter 25 to the power supply line. When the receiver 211 confirms that the transmitted data is addressed to itself, the receiver 211 turns on and off the power, causing the right blinkers 11 and 12 to blink.

Similarly, the receiver 21 for controlling the left turn signal
2 to control the left turn signals 15 and 16, receiver 213 for night lamp control, headlamp 13 and combination tail lamp 14, and receiver 2 for brake switch.
15 for the combination lamp, phone control receiver 216 for the phone 20, and high beam control receiver 2.
14, the headlamps 13 can be operated as high beams. In this way, by using a transmitter and a receiver, there is no need to perform complicated wiring as in the past, and control commands for electrical components can be centrally issued. Therefore, failures in electrical components can be detected early.

Next, the internal configurations of the transmitter and receiver shown in FIG. 1 will be explained.

FIG. 3 is a block diagram showing the internal configuration of the transmitter in FIG. 1. In the figure, the transmitter includes an address setting switch 36 for specifying the electrical equipment to be turned on, and an address selector (ADDRESS SEL) 32.
, a modulator (MOD) 33 that modulates the signal from the address selector, and a hand-pass filter (BPF).
) 34, and a transformer 35 and a capacitor 37 superimpose an address signal, which is a control command, on the DC signal of the power supply line 31.

FIG. 4 is a block diagram showing the internal configuration of each receiver in FIG. 1, and shows the configuration of receiver 215 as an example. In the figure, the receiver has a power line 31
It supplies a power supply voltage to the combination tail lamp 14, and has a function of extracting the address signal superimposed on the DC signal of the power supply line 31. To achieve its functionality, the receiver includes a capacitor 49 and a transformer 42.
, a bandpass filter (BPF) 43, a demodulator (DEMOD) 44 that demodulates the address signal, and a demodulated address signal and an address setter (ADDRES).
S) 45, and a determiner 46 which sends out a drive signal for the switch 47 only when they match. Note that a relay, a thyristor, or the like may be used as the switch 47.

[0022] In such a configuration, a drive signal is sent from the determiner of only one of the plurality of receivers provided, which has an address setter corresponding to the address set by the transmitter. This will cause the corresponding electrical equipment to light up,
It makes a sound.

In other words, when you want to operate an electrical component, if you set the address corresponding to that electrical component in the transmitter, this will be superimposed on the power supply as a control command and sent, and the receiver will extract it before the electrical component. This eliminates the need for control wiring.

[0024]

Effects of the Invention As explained above, the present invention combines a control signal for controlling electrical components as a modulation signal with the DC power supply of the power supply wiring, and transmits the modulation signal from the power supply line in front of the electrical component to be operated. By extracting and controlling electrical components, there is an effect that electrical wiring in a car can be rationally configured using only a power line, a control signal transmitter/receiver, and a relay.
