高通讯速率共零线电流环技术研究

High Communication Rate Common-null Current Loop Communication Circuit

为了缩短空中下载技术(OTA)升级时间并提高空调内外机火零线电流环通讯可靠性,我们提出了高通讯速率共零线电流环通讯技术。该技术通过更改电流环电路硬件设计使通讯电路数据传输速度更快,同时提高通讯的可靠性和稳定性。结果表明空调OTA升级时间和通讯可靠性显著提高。

In order to shorten the upgrade time of over-the-air download technology(OTA)and improve the reliability of air conditioner internal and external fire zero-line current loop communication,we propose a high-rate common-zeroline current loop communication technology.By changing the hardware design of current loop circuit,this technology can make the data transmission speed of communication circuit faster and improve the reliability and stability of communication.The results show that the upgrade time and communication reliability of air conditioning OTA are significantly improved.
