Problems solved by technology

[0002] The power line communication control system is a popular control technology in recent years. The advantage is that the existing power line can be used for control. However, when it is used to control lighting devices or general electrical appliances, problems encountered include: poor compatibility with existing electrical equipment, power line The communication carrier is susceptible to noise interference generated by other electrical equipment, the overall power consumption is high, and it is prone to noise and signal distortion when the transmission distance is long

Abstract

The invention relates to a method for keeping quality of a power line communication carrier, which comprises the following step of electrically connecting a switching assembly to one of a fire wire and a ground wire of a power line and a load, and electrically connecting at least one choking assembly to the other one of the fire wire and the ground wire of the power line and the load. The choking assembly is provided with an iron core corresponding to a hysteresis curve. When the switching assembly is not conducted, the iron core of the choking assembly is operated near a zero point of the hysteresis curve so as to avoid a case that the iron core is saturated to transmit the power line communication carrier to the load. When the switching assembly is conducted, the iron core of the choking assembly is operated in a saturation region of the hysteresis curve, so that the iron core is saturated without transmitting the power line communication carrier to the load. Therefore, effects of keeping quality of the power line communication carrier and avoiding distortion caused by long-distance transmission can be effectively guaranteed.

Description

technical field [0001] The invention relates to a method for controlling a power line communication carrier, in particular to a method and a device for maintaining the quality of a power line communication carrier. Background technique [0002] The power line communication control system is a popular control technology in recent years. The advantage is that the existing power line can be used for control. However, when it is used to control lighting devices or general electrical appliances, problems encountered include: poor compatibility with existing electrical equipment, power line The communication carrier is susceptible to noise interference generated by other electrical equipment, the overall power consumption is high, and it is prone to noise and signal distortion when the transmission distance is long. [0003] Therefore, how to realize the compatibility between the power line communication control system and the existing electrical equipment, improve the anti-interf...
