X.10协议及应用

X.10 protocol and its applications

信号采集与控制的发展方向是实现数字化,但对于分散数据的采集和控制的布线方便与成本低廉兼顾是难点。X.10是利用电力线载波方式进行家庭自动化信息传输的协议,该协议不要求重新布线,对于要求低廉成本的应用是最好的选择。X.10采用调制方式传送,有较高的抗干扰能力,可靠性较高;传送速率较慢,只适于低速网控制。文章介绍了X.10协议的特点,给出了典型的电路框图、软件实现的程序流程图。对X.10设备的关键电路中的接口电路、过零检测电路进行了研究。

X. 10 is a protocol of home automation information transmission, which utilizes the power line carrier to carry on the signal. There are many advantages to use this kind of transmission mode, such as low cost, using installed power line, high anti-interference ability and reliability. But its transmitting rate is low and only suits for low-speed net controlling. The article introduces the characteristics of X. 10 protocol, gives out the typical circuit block diagram, program flow chart and interface circuit, and studies the circuit to measure cross zero signals.
