Description

A kind of digital power line carrier wave illuminating switch

The utility model relates to a kind of power switch, especially a kind of digital carrier switch.

Present power line carrier switch adopts frequency signal as control signal, and Chinese patent ZL90203607 discloses a kind of technology of using the frequency signal carrier wave to control street lamp on power line, and the shortcoming of this technology is to control the switch of single channel power equipment.

The purpose of this utility model is to provide a kind of carrier number code switch that can control multiple power equipment, overcomes the shortcoming that can only control the single channel power equipment.

Technical solution of the present utility model is to add digital signal in the carrier signal, distinguishes different power equipments, specifically is that one group of equipment has one group of identical address code, distinguishes in one group of equipment each independently power equipment with different numeric data codes.

Description of drawings

Fig. 1 is a digital signal generating means circuit diagram of the present utility model,

Fig. 2 is a digital receiving system circuit diagram of the present utility model,

Below in conjunction with drawings and Examples the utility model is elaborated,

The digital signal generating means is by data input buffer circuit 2, digital coding circuit 1, carrier wave generation circuit 3, amplifying circuit 4, coupling circuit 5 is formed, k1 BG1 C1R1 R2 constitutes a circuit-switched data input buffer circuit, when switch k1 closes, BG1 is that transient state is ended, with capacitor C 1 charging, back BG1 conducting about time-delay 10ms is to high level of data input pin input of the circuit 1 (MC45026) of setting address code, to set up corresponding numeric data code, the output of digital coding circuit 1 (MC45026) is exported once the numeric data code of working out, this string data sign indicating number sends through the row modulation with the frequency of 150KHZ---300kHZ carrier circuit 3 (EN555), after amplifying circuit 4 (BG5) amplifies, sends into power line through the capacitor and inductor coupling circuit 5 (M1) that selecting frequency characteristic is arranged.

Carrier signal through power line transmission to the digital signal receiving system, be coupled by capacitor and inductor coupling circuit 6 (M2), carrier signal is received to amplifying circuit 7 (BG2), amplify the back and detect digital signal by detecting circuit 8 (D1), input to the input of digital signal decoding circuit 10 (MC45027) after handling by integration shaping circuit 9 (G3 C4 R4 BC1 R3) again, have only when the address code of MC45027 is identical with the address code that sends chip MC45026, digital signal just is received, the data output end output of digital signal decoding circuit 10 (MC45027) and the control signal of corresponding certain the road lighting apparatus of coding circuit data terminal, then by bistable circuit 11, controllable silicon 13 or relay are triggered, the switch of control lighting apparatus in buffer circuit 12 output backs.

The utility model has the advantages that and in a single channel homophase power line loop, to control independently lighting apparatus of multichannel simultaneously, compare to have strong interference immunity with infrared remote control and ultrasonic remote control, non-directive, advantages such as far distance controlled adopt digital technology, control is reliable, and is simple in structure.
