Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power line carrier remote control system.

In general, the input data input by opening and closing the input contact (4) corresponds to the output contact (4) by 1:1 +51
This type of remote control system is designed to connect input 5 (6) and output 5 (7) via signal lines (4), respectively, as shown in Figure 1. n
Pair input/output # (61 (If 71 is provided, it is necessary to wire at least n+1 signal lines consisting of n signal lines (A) and one common signal M (Ac), Furthermore, it is necessary to separately wire a power line to supply power to each input/output section +61 (7), which complicates the wiring work and has the drawback that it is troublesome to change the wiring when changing the layout. The present invention aims to solve the above-mentioned drawbacks.An embodiment will be described below with reference to the drawings.Figures 2 to 5 show an embodiment of the present invention. The transmitting terminal (Ti) has a rate coupler for data input and six logic operations (such as microcoscipiputers).

It is composed of a transmitter that creates ij (Vs) and outputs it to the power line (3), and a power source sO4. In the figure, the input terminal to which the OUT input contact (4) is connected, and the haze indicate the commercial power supply (A
It is an output terminal connected to the power line (3) of C).

Now, the input contact (4) such as the output switch or the Fi operation switch (ν) is inserted in series with the light emitting diode of the present invention, and the open/closed state of the contact is determined by logical operation via the photocoup 5-. H1l), and the input contact (4) and logic operation section (11) are electrically insulated. Logical operation S (In the river, the address setting switch (, 11m)
(12b) A complete transmission layer is formed by adding the calling address and start mark set in (12b). The transmitter (the transmitter) controls a high frequency oscillation circuit according to the above transmission data to create a carrier signal (VB) and sends it to the power line (1) via the Calapric flow.

On the other hand, a receiving terminal unit +2) a receiving unit - which receives the Fi carrier signal (Va), and an address setting S? which sets a unique address. A logic operation section consisting of a phantom and a microcomputer (
The receiving section receives the carrier signal (v8) superimposed on the commercial power source (AC) and reproduces the transmitted data (D8). However, in the logical operation section, the call a' containing the transmission data (Ds) K is

That is, in the embodiment, the power supply voltage supplied from the power supply S- is outputted via the output contact +61 which is controlled based on input data. However, the output contact (li+) may be a switching element such as a thyristor or a transistor.

FIGS. 6 and 7 show another embodiment in which the output (Vo) of the logic operation section controls the relay 4 via the relay drive S. The output contact (5), which is a relay contact, is a so-called voltage-free contact.If a series circuit of the output contact (5) and the load is connected between the power lines (3), the load will become the output contact 15). K can be directly controlled.

Figures 8 and 9 show still other embodiments.
Input data input to the transmitting terminal (1) is set by multiple input contacts (4), and several bits (English) to
