基于W5100的网络远程抄表系统的设计

Design of the Network Remote Meter Reading System Based on W5100

针对目前国内人工抄表效率低、实时性差,现有GPRS等无线远程抄表系统可靠性差、成本高等问题,提出了基于硬件协议栈的以太网通信模块W5100的远程抄表方案。介绍了远程抄表系统的组成和工作原理,阐述了软硬件设计。用于水表数据采集的测试结果表明,该系统能够方便快捷地接入网络,稳定可靠地抄取水表数据,在水表等智能仪表抄表领域可高效实现远程自动抄表。

At present, the manual meter reading method features low efficiency and poor real time performance, while the wireless remote meter reading systems using such as GPRS technology features low reliability and high cost, thus the remote meter reading strategy based on Ethernet communication module W5100 with hardware protocol stack is proposed. The composition and working principle of such system are introduced, and the design of hardware and software is described. The test results of using it in water meter data acquisition indicate that the system can be easily connected into the network and fetches the data from water meters reliably and stably, it can effectively implement remote automatic meter reading in intelligent instrument meter reading areas including water meter.
