摘　　要：用1台PC机和2台PLC设计了1个5层楼2部电梯运行的计算机仿真模型。1台PC机既作为系统的监控上位机,又可实现两部虚拟电梯的显示界面;每部虚拟电梯的运行各由1台PLC控制。PC机上的电梯仿真模型与监控、通信程序用VB6.0实现,PLC的通信、控制程序使用西门子S7-200系列的PLC的专用编程软件STEP 7-Mcro/WIN实现。仿真测试表明,系统设计方案可行,在虚拟电梯的显示界面上操作,虚拟电梯可在PLC的控制下正确的运行,且可以查看电梯运行的各个参数。系统经济性高,界面友好,延展性强,特别适合应用于高校实验教学和科研中。A computer simulation model with two five - story elevators was designed by one PC and two PLCs in this paper. The PC can not only be used as a host computer in the monitor, but also display the interface of the two virtual five - story elevators running, among which one virtual elevator was respectively controlled by one PLC. VB6. 0 software was used to compile a control and communications of simulation model of the elevators in the PC, and a special program software STEP 7 - Mcro/WIN widely used in SIEMENs S7 - 200 series PLC was used to design com- munication and control for the PLCs. The simulation results show that the design of the control system is feasible ; the virtual elevator can be operated in the display interface. Moreover, the virtual elevator can run under the control of the PLCs, and every parameter can be checked in the interface. This system has the advantages of high economics, good interface and strong application
