摘　　要：文中设计了一款基于单片机控制的软启动器。采用集成度高的晶闸管智能控制模块作为软启动器的主电路,利用STC89C51单片机作为核心的控制芯片完成电流、温度的检测和晶闸管模块的控制。首先对STC89C51硬件电路原理图及外围电路设计,然后给出了晶闸管模块控制电路原理图,最后将所设计的软启动器装置在实验室进行了实验,验证所设计软启动器装置功能的正确性和有效性。实验结果证明了该装置的正确性和可行性。A soft starter is designed in the paper ,which bases on single-chip control. Taking high integration of thyristor control module as the main circuit of soft-starter, STC89C51 SCM as the core control chip to complete current, temperature detection and control of thyristor module.First of all, STC89C51 peripheral circuit and schematic diagram of hardware circuit is designed, then a schematic diagram of control circuit for thyristor modules is derived. Finally, with the aim at testing the performance of the soft Starter devices in this paper experiment in laboratory is completed. Experimental results proved the correctness and feasibility of the device.
