摘要
针对吊伞在使用安全性和方便性等方面的不足,提出以AT89C51单片机为核心控制单元,通过对风速和光线强弱的检测,实现对吊伞的自动化改造,使之具有随风速大小和光线强弱而自动开关的功能。在对用户需求分析基础上,给出了系统的总体设计方案,并着重讨论了风速检测、光强检测等关键技术。最后,给出了系统软件设计框图。试验表明,该系统可靠性高、稳定性好,能够满足用户需求,经改造过后的自动化吊伞已投入到生产中。
According to the insufficiency of safety and convenience for a hanging umbrella, a control unit, in which single-chip conputer AT89C51 is used as its core, is put forward. Wth the unit, the hanging umbrella possesses the function of automatic on-off according to wind speed and the brightnes of light. In the paper, the general design scheme is given and the key technology involving wind speed detection and bright of light is discussed and the design flow chart of the system software is introduced based on the analysis of user requirements. The experimental result indicates that the method will improve the stability and reliability of the system, and the improved hanging umbrella has put into production.
