一、NB-IOT物联网远传水表简介(以下简称NB-IOT水表)

NB-IOT水表是基于NB-IOT窄带蜂窝技术无线通讯的低功耗无线远传水表,水表的读数采用光电直读技术直接判断水表字轮的位置,是基于光电技术和微电子技术的一种“位置识别排列五奇偶走势图技术,从而读取字轮读数,与传统脉冲水表相比,采用分体式设计,电子单元安装在独立的全密封腔体内,防水性能达到IP68等级,不会受到光线干扰等问题,不改变传统湿式水表结构,不影响传统湿式水表计量精度及灵敏度,它可将读数误差降低至零,水表检定周期到期后只需更换水表基表,电子单元能继续使用。是自动抄表系统中机电转换零误差的电子远传水表,且采用微功耗设计,编码校验技术,具有灵敏度高,抗干扰能力强,传输距离远等特点。
