| 摘 要： | 本文根据电动大门对速度的要求，给出了由８０３１单片机、变频器电路及其驱动电路等组成的电动大门控制系统．本控制系统的特点是硬件线路比较简单．所设计的软件只用一个定时器即可产生频率变化的ＳＰＷＭ信号．采用本控制系统可比较经济地使电动大门按给定的速度曲线运动．因此可解决现有电动大门所普遍存在的，由于速度单一而带来的各种问题．

| Abstract: | In this paper is presented a control system for electric gate composed of onechip microprocessor, frequency conversion circuit and drive circuit, etc. Simple in hardware composition, the control system can operate a timer software to generate sine pulse width modulation signals (SPWD signals)with variable frequencies,which set the electric gate into motion in a manner as required by the given speed curve in a less expensive way, thereby solving the problems caused by one-speed motion in existing electric gates. |

| Keywords: | electric gate speed regulation by frequency conversion control by one-chip microprocessor |
