摘　　要：介绍了一种由单片机AT89C2051与接口电路组成的舞台提升控制系统,该系统具有功能强大、硬件开销少、安全、可靠等特点。选用具有复位功能和看门狗定时器的MAX813L,提高单片机的稳定性和抗干扰能力,保障了系统的正常运行。通过对吊杆上升、下降的定位,从而实现舞台照明系统的自动化、理想化艺术效果。该系统已成功应用于某电视台舞台提升控制系统中。In the paper, a kind of control system was made up of MCU AT89C2051 and interface circuit to promote the stage is introduced. The system has a powerful, less hardware expenses, safe, reliable characteristics.Using MAX813L that can restore to the position and has watch dog timer function to improve the stability and antiinterference ability of MCU, the system has been ensured normal running. Through the localization of rising and dropping to the boom, thus it realizes the stage lights systematic automation and idealizes the artistic result. The system has already succeeded in applying to the control system promoting the stage of some TV station.
