針對目前電梯生產企業普遍存在的電梯現場調試的問題，設計了電梯現場仿真調試系統，并詳細闡述了其工作原理、系統組成以及軟硬件設計。系統由單片機構建的下位機
和使用VB 語言編程實現的上位機構成。通過旋轉編碼器測量的脈沖數據計算實際電梯的運行距離，并利用RS232 串行通信技術在下位機和上位機之間進行實時數據交換，在上位機中實現對電梯現場的真實模擬，下位機實時模擬輸出各開關信號，以實現在廠內較準確地調試電梯快車功能。

Abstract: Aiming at the problem about the elevator commissioning in scene existed in most
of elevator factory, designs an elevator scene imitating commissioning system and explains its
principle of working, system composing, hardware and software. System is made up of the down machine composed on MCU and the up machine based on VB. Depend on the pulse from rotary encoder, computes the real run distance of elevator; and exchanges the data between the down and the up machine based on RS232 serial communication. The up machine imitates the scene of elevator running, the down imitates to output real-time switching signal. Then it can help to adjust the elevator commissioning well and truly.
