摘要
采用PLC调节电机速度具有体积大,成本高的缺点,为使电机调速系统具有操作简单、运行安全可靠和成本低廉等优点,设计以AT89C2051单片机为核心的红外遥控系统,给出系统的硬件组成和软件设计方法。系统由发射和接收2部分构成,用软件控制电机的电压值,从而调节电机速度。在测试使用后,证明其方便、可靠并具有实用价值,从而为电机调速提供了一种设计思想和方法。
Adopting the PI.C to adjust elecromotor's speed has shorteomings of big bulk and high cost, in order to make elecromotor's speed governing system have follow advantages:its operation is easy and its running is safe and firm, its cost is cheap. The design of an infrared remote- control system is based on AT89C2051 single chip microcomputer. Its system compo sition and design of hardware and software are presented. System includes two parts: emission circuit and receive circuit,it uses software to control elecromotor's voltage and thus adjust elecromotor's speed. It proves that this system is convenient,reliable and practical after using it. Therefore it provides the design theory and method for adjusting elecromotor's speed.
