摘要：隨著我國經(jīng)濟(jì)的高速發(fā)展，微電子技術(shù)、計(jì)算機(jī)技術(shù)和自動(dòng)控制技術(shù)也得到了迅速發(fā)展，交流變頻調(diào)速技術(shù)已經(jīng)進(jìn)入一個(gè)嶄新的時(shí)代，其應(yīng)用越來越廣。而電梯作為現(xiàn)代高層建筑的垂直交通工具，與人們的生活緊密相關(guān)，隨著人們對其要求的提高，電梯得到了快速發(fā)展，其拖動(dòng)技術(shù)己經(jīng)發(fā)展到了調(diào)頻調(diào)壓調(diào)速，其邏輯控制也由PLC代替原來的繼電器控制。
 本次設(shè)計(jì)是以電梯控制技術(shù)為背景，針對以前的拖曳電梯的一些缺點(diǎn)，采用現(xiàn)在流行的PLC控制技術(shù)、變頻調(diào)速技術(shù)、現(xiàn)場總線技術(shù)來實(shí)現(xiàn)電梯的各種控制。用西門子S7-300控制電梯的常規(guī)控制，并且通過S7-400與工業(yè)以太網(wǎng)上的上位機(jī)進(jìn)行通訊，上位機(jī)通過軟件可以對電梯進(jìn)行實(shí)時(shí)遠(yuǎn)程監(jiān)控。而電梯的升降、起停的速度由變頻器控制，樓層的位置由旋轉(zhuǎn)編碼器來檢測。

The designed of the elevator system of frequency conversion timing based on siemens PLC

Abstract: With the development of the economy, microelectronic technology, computer technology and the automatic theory are developed rapidly, the AC variable frequency technology has been in a new state. Its application is becoming more and more widely. But the elevator as an important traffic in skyscraper，it also has developed quickly with the improving requirement of the people .Its dragging technology has developed from DC timing to AC variable frequency timing and its logic control- relay control also has been replaced by PLC.
 On this paper, it was based on by the control technology of the elevator, aim at the some weakness of the haulage elevator of the past, the popular PLC control technology and change the adjust soon total line in technique, the spot technique were adopted to every kind of control that realizes elevator. Siemens S7-300 was adopted to the programmable control in this subsystem, and was communicated through S7-400 with the computer of Industral Ethernet ,  The computer passes the software can proceed to the elevator with the on time long range supervises and control. but the rise and fall、rises to stop speed of the elevator was controlled by the transducer, The place of the floor was examined by revolution coder.
