Abstract

The invention discloses a power-switch data communication method, system and light cluster, wherein the system sending end generates data signal to be amplified by a control module, the data line as media transmits signal to a receive node, the latter processes the signal to obtain control signal for target. This invention applies dc for well anti-interference capacity, free to limits of loading and transmission distance within power output range and line attenuation feature, realizes minimal module, and reduces product cost greatly.

Description

technical field

[0001] The invention relates to a communication method, a system and a light string applying the system. In particular, the invention relates to a communication method and system for generating data by controlling power on and off. Background technique

[0002] At present, point-to-point or point-to-multipoint data transmission technologies are divided into direct transmission and drive transmission in terms of types, and divided into direct transmission, linear drive transmission and differential signal transmission in terms of implementation.

[0003] Direct transmission is to use the drive capability of the output port to directly communicate with the load. The most typical application of this transmission technology is serial communication. These transmissions are simple to implement, but the transmission distance is short and the load capacity is poor. For example, the actual application distance of serial communication will not exceed 15 meters, and th...
