| 摘 要： | 水表的出户计量已经成为亟待解决的问题。介绍了一种水表计费系统。该系统将水表的计量数据通过RS485总线传到楼下的水表计费柜，定期由工作人员将计量数据采集到便携式读表器内。该读表器通过RS232接口将采集的数据传到上位机，完成水表计费数据的采集、存储和处理。实践证明：该系统实现了水表的智能化设计和户外抄表。

| Abstract: | Water meter out-door reading has become an urgent need. A billing system of water meters is presented in this paper. The metering data of water meters are transferred into billing cabinet downstairs through RS485 bus, the operator collects the metering data into portable reader periodically. Then the data collected are forwarded into host computer through RS232 interface for data acquisition, storage , processing and billing. The practice proves that this system implements intelligent design and out-door reading for a water meter. |
