C8051在水表计费系统中的应用

水表的出户计量已经成为函待解决的间题。介绍了1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，定期山T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卜位机，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二Water meter out-door reading has become an urgent need. A biling system of water meter; is presented in this paper. The metering
data of water metem are transferred into billing cabinet downstairs through RS485 bus, the operator collects the metering data into portable reader
periodically. Then the data colected are forwarded into host computer through RS232 interface for data acquisition, storage, procesing and
billing. The practice proves that this system implements intelligent design and out-door reading for。water meter.
