摘要伴随着电力领域的电子技术，现代电脑微机技术，现代自动控制技术的迅速发展，三相交流电机的启停在节能，稳定性，安全性方面有这迅速的提升，成为电气传动的主要发展方向。通用软启动器，HMI（人机界面技术）以及可编程的逻辑控制器以其优越的起保停性能，高效，高功率因素和明显的节能效果而广泛应用与重载交流电机等，被认为是最有发展前途的启停控制技术。
可编程控制器的设计可以说是以苛刻的工作环境为前提进行的设计，在使用中它的实用得到一步步验证。机械制造，冶炼金属，化学工业，电力，运输和建筑等众多领域的控制都是我国的重工业，它们对控制的要求极其苛刻，在这样的情况下最为工业必不可少的控制器，可编程控制器得到了充分的证明。46092
亲和的人机界面会赢得人们的好感，就拿今天流行的智能触屏手机，而触摸屏同样在工业中为自己赢得了自己的一片天。
软启动器由于他的稳定性而被广泛使用。
我的设计初衷是运用可编程控制器，通过D/A数据转换模块传递数据，进而通过固态继电器控制电机的软启动和停止，通过CC-LINK通信将电机工作情况显示在触摸屏上，并实时控制，最后得出这一设计的固态继电器软启动器系统的可行性结论。

 ABSTRACT  With the development of power electronic technology, computer technology, the rapid development of modern automatic control technology, AC motor of the gradual start stop in energy saving, stability and safety aspects have the rapid increase, become the main development direction of electric drive. General solid state relay, HMI and PLC with its superior play of suspension performance, high efficiency, high power factor and significant energy-saving effect and extensive application and large and medium-sized AC motor and so on, is considered to be the start stop control technology for the future development.
  Programmable logic controller (PLC) is a specialized in industrial environment application and design of digital operation electronic devices, due to the programmable controller's own personality and advantages, in the machinery manufacturing, metal smelting, in many areas of chemical industry, electricity, transport and construction control has been widely used.
  Touch screen as a man-machine interface, with its affinity to the man-machine interface to win the broad masses of praise.
  Solid state relays are widely used due to their stability.
  The text mainly expounds the programming controller through the D / a conversion module with solid state relay control motor soft start and stop the motor work displayed on the touch screen and real-time control. Finally a conclusion on the feasibility of the design which is a solid state relay soft starter system through the CC-Link communication.
Key words: HMI; PLC; solid state relay; three squirrel cage AC motor
