摘要
针对现代小区逐步向着智能化、互动化方向发展的要求,下面提出了一种基于ARM(S3C6410)和WiFi的远程自动抄表系统设计;前端电表与采集器之间的下行通道采用的是RS485总线模式,增强了电表接入的可扩展性;采集器与主站之间的上行通道采用了WiFi和Internet这种无线与有线相结合的异构网络模式,提高了数据传输的速率和组网的便捷性;在完成电表的选择及与采集器的连接、采集器、无线接入模块、主站4个部分的设计后,给出了相应的软件设计,最后搭建由电表、采集器、无线接入点、主站组成的试验系统来验证系统数据通信的稳定性与数据传输的可靠性,经实验证明,该系统能够快速的建立网络通信,具有传输数据快、可靠性高、实时性好的优点。
In view of requirements that the modern community gradually is towards intelligent, interactive development. This paper has realized a remote automatic meter reading system based on ARM （$3C6410） and WiFi. The descending channel between the front end meter and collector adopt the RS485 bus mode. It enhanced the scalability of the meter access. The uplink channel between the collector and master station used construction combined wireless with wired heterogeneous network model. This model is composed of the WiFi and the lnternet. It improved the rate of data transmission and the convenience of establish network. We will provide the corresponding software design after completing the meter choice and the collector connection, collector, wireless access module, master station design. An experiment system consisted of the meter, collector, wireless access point and host is used to test the stability of data communication and the reliability of data transmission of the system. The experiment suggests that the system can quickly set up network communication, and have the advantages of high data transmission speed, high reliability, good real--time performance.
