摘要:
针对广告牌突遇强风意外损坏的问题,从动态减小广告牌受风面积的角度,设计了一种强风卸载广告牌及其自动控制系统.该系统能够在外部风力超出广告牌设计强度时发出预警,并快速启动卸载装置以减小广告牌的受风面积,风速减小到安全范围后,广告牌自动恢复原状.重点介绍了这种广告牌的组成、工作原理,并详细介绍了系统的硬件和软件设计,给出了系统硬件框图和软件流程图.系统以风速传感器为现场风速测量元件,以AT89S52微控制器为控制核心,采用128*32屏幕点阵液晶作为显示元件,薄膜按键作为输入装置,完成实时风速检测和显示、预警风速和安全风速设定、危险风速报警、系统强风卸载和安全恢复等控制功能.
Abstract:
Fo r b illboard acc identa ldam age in strong w ind, th is paper, from the perspective of dynam ica lly reducing b illboa rd w indw ard, g ives a new w indload un loading b illboard design and its auto contro l system. To the security o f b illboa rds, this system would send ou t a larm signals, and startup the un loading dev ice qu ickly, when ex ter ior w ind pow e r go beyond the design streng th o f b illboards. When thew ind speed w as reduced to sa fe range, the b illboa rd w ou ld re turn to the o rig ina l state. This paper introduces the composing, wo rk ing pr incip le, working flow and contro l log ic of th is design, and show s the system princ iple frame cha rts and softw are flow charts. To achieve the functions such as rea ltim e w ind speed testing and d isp lay ing, prea la rm and safe w ind speed setting, dang erous w ind speed a larm, w indload un load ing and safety resum e, th is system is com posed o fw ind speed senso r, AT89S52 SCM, 128* 32 la ttice LCD and pe l lic le keys, w hich w ork as liv ing w ind speed test componen t, control core, d isp lay component and input com ponent.
