本文在分析帶式輸送機的工作過程的基礎(chǔ)上，對機械電子式軟起動裝置的控制系統(tǒng)進
行了研究，對控制系統(tǒng)進行了硬件與軟件設(shè)計。使用可編程控制器對變頻器的輸出頻率進行控制，實現(xiàn)對調(diào)速電機轉(zhuǎn)速的控制。調(diào)速電機與主電機的轉(zhuǎn)速經(jīng)差動行星輪系的速度合成，可使傳動系統(tǒng)在很大范圍內(nèi)無級調(diào)速，實現(xiàn)對負載的可控起動。

Abstract: On the basis of analyzing the working process of belt conveyor, the control
system of the mechatronics soft start equipment is studied，the hardware and software
are designed for control system. The programme logic controller is utilized to
control the inverter's output frequency which accomplishes controlling the
velocity of speed-controlling asynchronous moter .The velocity between main
asynchronous moter and speed-controlling asynchronous moter is composed by way of
the differential planetary gear train，the tranmission system is made to regulate
velocity stepless in large scope which succeed in controlling starting progress of
load.
Key words: Mechanical electron,PLC, Belt conveyer
