摘要: 过零调制技术完全利用现有电力网络为传输载体,无需额外增加系统设备,成本低廉。文章介绍了基于过零调制技术的温湿度报警系统的整体设计及组成,经现场应用表明,设计合理,可靠性高。Abstract: The zero-cross modulation technology uses exsisting power distribution network as transmition carrier. Because it needn’t increase additional system equipments, it is low-cost. In this paper, the design of alarming system of temperature and humidity based on zero-cross modulation technology and the constitution were introduced. By field application, it made chear that the design is in reason and the reliability is high.
