摘要
介绍一种基于Wi-Fi自动抄表系统的硬件和软件实现方法,给出智能抄表系统的总体框架结构,详细叙述了其中的无线中继、接入点、控制中心等各部分硬件结构和各自的作用。硬件平台采用Marvell的88W8686和ARM7处理器及其外围电路构成无线监控通讯终端。控制器的软件基于嵌入式μC/OS-Ⅱ操作系统平台,利用LwIP协议的移植实现了TCP/IP协议,在VC++和数据库上实现了上位机的抄表管理软件,可以通过计算机管理系统对电表的读数进行统计管理和收费,以及对仪表的运行状态进行监控,从而实现了自动抄表的目的。该系统结构灵活实用,有效解决了抄表的安全性和效率问题。
Introduced hardware and software method of a automatic meter reading system based on Wi-Fi. Given the whole framework of AMR, described the wireless repeater, access point, the control center of the hardware structure and the respective roles in detail. Hardware platform which make up of Marvell 88W8686, the ARM7 processor and its peripheral achieve circuits wireless monitoring. Using μC/OS-Ⅱ operating system and LwIP protocol to achieve Wi- Fi communication. Using VC＋＋ and database to achieve the PC management software of meter reading, using the computer management system of the meter readings to realize the statistical management and billing, as well as monitoring the running status, thus achieving the purpose of automatic meter reading. This system is flexible, practical, and effective to solve the problem of security and efficiency.
