摘要
本系统采用单片机AT89S52作为自动控制升降旗系统的检测和控制核心,采用由单片机控制的步进电机带动国旗升降,实现对国旗升降的自动控制。该电路主要分为电机驱动控制模块、键盘与显示模块、语音模块及无线遥控电路模块等几个部分。电机驱动控制模块采用集成驱动芯片L298,控制与显示部分分别采用键盘作为控制和液晶RT1602C作为显示,语音电路采用语音芯片ISD2560,无线遥控部分采用SP多用途无线数据收发模块,同时还采用了接近开关LMF2-3005NA,防止旗帜在最高点或最低点误动作,从而实现了双重保险的作用。基于这些完备而可靠的硬件设计,使用了一套完善的软件编程,实现了自动升降旗的基本功能及发挥部分的一些功能。

Abstract
This system uses monolithic integrated circuit AT89S52 to take the automatic control to rise to lower a flag system's examination and the control core, uses controls by the monolithic integrated circuit step-by-steps the electrical machinery to lead the national flag fluctuation, realizes to the national flag fluctuation automatic control. This electric circuit mainly divides into the motor-driven control module, the keyboard and the display module, the pronunciation module and the wireless remote control electric circuit module and so on several parts. The motor-driven control module uses integrated actuation chip L298, the control and the demonstration part uses the keyboard separately takes the demonstration as the control and liquid crystal RT1602C, the pronunciation electric circuit uses speech chip ISD2560, the wireless beep box uses the SP multipurpose wireless data receiving and dispatching module, meanwhile has used proximity switch LMF2-3005NA, prevents the flag in the peak or the bottom misoperation, thus has realized the double check functions. Based on plete and reliable hardware design, has used a set of perfect software programming, has realized the basic function which and display part some functions rises to lower a flag automatically.
Key words Step-by-steps the electrical machinery, Automatic control, Liquid crystal display, Proximity switch
