As the development of the carrier-current technology, the predominance of the carrier – current communication is more obvious. 随着电力载波技术的不断发展,电力载波通信的优势越加明显。
The communication systems wildly used nationally and internationally, such as audio frequency wire communication, carrier-current communication, micro-wave communication, optic-fiber communication, expanding frequency communication and satellite relay communication, are investigated in detail. 对目前国内外使用较多的一些通信方式如音频线通信、载波通信、微波通信、光纤通信、扩频通信、卫星帧中继通信等进行了较为深入的分析和研究;
Firstly due to the complexity of power as a communication channel, analyzed the power line carrier-current communication channel characteristic of power line carrier-current communication channel and the noise, impedance and attenuation characteristics are analyzed, and the power line carrier-current communication channel model. 首先鉴于电力线作为通信信道的复杂性,分析了电力线载波通信的信道特性,对电力线载波通信信道的噪声、阻抗和衰减特性进行了分析,并给出了电力线载波通信信道模型。
Puts forward lighting control system scheme of choice, based on the power line carrier-current communication lighting control system for carrier technology and carrier chip, and design a host and terminal hardware circuit. 提出了照明控制系统的总体方案,选择了基于电力线载波通信的照明控制系统的适用载波技术和载波芯片,并设计了主机和终端的硬件电路。
