摘要
本文介绍了用于水、电、气三表集抄系统的光电编码角位移传感技术。光电编码器测量出数字轮当前角度,它有 20 个编码,采用 5 个发射管、5 个接收管和 2 个码道的设计方案。直读表具的数据通过集中器采集到管理系统,实现了三表的集抄。
A angle displacement transduced by photoelectric coding is presented in this paper. The coding device is used to an Automatic Meter Reading (AMR) system for water, gas and watt-hour meters. The photoelectric coding consists of five light emitters and five receivers and two coding tracks with twenty codes . Data corresponding to angle of number wheel is transformed to code, which can be collected by the management system with a data concentrator.
