Abstract

The invention discloses a method for controlling alternating current digital coding. A controller uses a power driver member to performing digital pulse coding on a trailing edge of positive and negative half waves of the alternating current, each half wave can be used for coding a coding bit, and a purpose of transmission of a digital controlled signal by using an AC power line. The provided controlling method uses the AC power line for transmission of the digital controlled signal, under condition that a control line is not added, digital control of loop equipment can be realized, fewer elements can be required by a system, and cost of the system is reduced. The digital coding method realizes accurate positioning control, compared with a phase-cut dimming system, the controlling method can greatly reduce harmonic wave interference, and can increase the reliability of the system.

Description

technical field [0001] The invention relates to the technical field of power line communication, in particular to a method for digital pulse coding and communication control based on power lines. Background technique [0002] In the existing power line communication technology field, the power line carrier communication method is often used, that is, the power line is used as the transmission medium, and the information communication and control between devices are realized by modulating the high-frequency carrier signal on the power line, so that each device node is equipped with high-frequency modulation The control circuit is relatively complicated, the number of components is large, and the cost is relatively high, so it is difficult to promote popular applications. [0003] In terms of commercial and household lighting control, the control network on the market now uses dedicated control lines for connection. For example, the DALI control system needs to lay two DALI bu...
