摘要
传统的电表抄表使用GPRS/3G/4G远程集中抄表,解决了原先人工抄表的一系列问题,但也产生了一些新问题,如数据中继环节多、集中器/计量终端成本高、结点通信费用支出高等。因此,通过NB-IoT+433M无线双模方案,以NB-IoT传输为主、433M无线+有线传输为辅的方式将采集到的电表数据经过数据采集、解密、分区等处理后,上传至电力计量主站系统,实现电表数据的实时采集及回传,有效地解决了GPRS远程抄表面临的技术难题。
The traditional meter transmission uses GPRS/3G/4G remote centralized meter reading,which solves a series of problems in the original artificial metering work.However,some problems have arisen:there are many data relay links,high cost of concentrator/metering terminal,high expenditure of node communication,overall cost of the system is expensive and difficult to control.Through NB-IoT&433M wireless dual-mode scheme,mainly NB-IoT transmission,supplemented by 433M wireless&cable transmission,the collected ammeter data are uploaded to the main power metering station system after data acquisition,decryption,partitionand so on.Real-time acquisition and return of meter data can effectively solve the technical problems faced by GPRS remote meter reading.
