一种用于智能用电终端的新型射频调节技术

A Novel Radio Frequency Regulating Technology for Intelligent Power Terminal

用电信息采集终端采用传统方法接入公网时,由于信号弱造成的用电信息采集终端无法上线或者采集数据无法上传,以及成本高,辐射大等问题,提出一种用于智能用电终端的新型中继调节技术。从射频电压合路和射频调节2个方面进行了设计,采用可重构波段参数匹配射频设计原理和智能双级增益补偿的自动电平控制技术,解决了多终端合路信号衰减问题,增强了信号质量,开发了样机,并通过了国家认证。

Due to the weak signal, when using traditional method of public access network, the electricity information acquisition terminal often can＇ t be on line, or can＇ t upload data normally, it also has the characteristic of high cost and high radiation. The electricity information acquisition terminal is designed from two aspects of RF voltage integration and radio frequency regulation. The problem of signal attenuation is solved and the signal quality is enhanced by adopting the design principle of reconstructed band parameter matching RF ＆ intelligent two - stage gain compensation automatic level control technology. The prototype is developed and has passed national certification.
