一种基于手机WiFi的无线测控技术及其应用

摘要

智能手机作为测控系统的移动监控终端具有良好的灵活性、便携性与便利性,WiFi通信由于其低成本高速率,运行环境兼容性高,成为一种比较实用的通信方式.该文构建了一个基于MSP430F149单片机的恒温控制应用场景,并将与智能手机的WiFi通信技术运用于该应用场景中,构成一个可通过移动终端远程监控的主从式测控系统.文中给出了系统的体系结构及硬软件设计方案,可为类似远程测控方案的实现提供借鉴.%As a remote mobile monitoring terminal of measuring and controlling system, smart phones has good flexibility, portability and convenience.Due to its low cost, high speed and high compatibility, WiFi communication has becomes a more effective way of communication.A thermostat system based on MSP430F149 single-chip microprocessor was introduced, combining with WiFi communication technology of smart phone, thus to construct a master slave control system which remotely monitored by a mobile terminal.The architecture of the system and the design scheme of hardware and software are given, which could also provide guidelines for the implementation of similar remote measurement and control programs.
