Elevator has become one of the important transport equipment. From the traditional domestic elevator control relays, contactors composition. It is not only the existence of poor reliability, high cost and high failure rate and other shortcomings, but also with the number of layers increases, changes to the manufacturing and installation of wiring inconvenience. Four-elevator as the control object of the simulation and control system of elevator. Implementation of the elevator with PLC control. The subject of design tasks is controlling four elevators with programmable logic controller (PLC) and achieve all the control requirements. The subject of design thinking is the random logic control theory, according to its own elevator control law in response to random external call signal. The design analysis and discussed the whole process of program design with FX2N PLC controlled model elevator, and described three main areas: control of the system requirements, system configuration, software design. 确eywor配sPLC control system elevator relay contactor 3 1.11501854260012031889121892150190119321951mmm.17( 4 1.2 1.2.1始始富始富始始始富始(1)(2)(3)(4)(5)(6)(7)善噪(8)1.2.2 ?r0嬉 5 (1) (2) (3) 1.2.3 PLC Programmble ControllerPCPLCPLCPLCCAD/CAM IEC1987 1.2.4 PLC 1968G.M 1969DEC ,Programmable Logic Controller 2070PLCPLC 20801632PLCPLCPLCPLCmmm?.17( 6 200PLC400PLCPLCPLCPLCPLCA-BAllen-BradlyGEGeneral ElectricMitsubishi ElectricOMRONAEGSiemensTETelemecanique PLC207080PLCPLCPLC PLCA-B PLC15%PLC 1.2.5 PLC 21PLCDCSDistributed Control SystemPLC(1)(2)(3)(4)(5)(6)(7)115V(8)115V/2A(9)(10)4K1.2.6 PLC PLC矽喁飓莠姝帑沫蛆廉帱郛鸣帙邙漾L 7 (1) PLC1/101/100 PLCFPLC30CPUPLCPLCPLCPLCPLCPLCPLC I/OPLCCPU PLCPLC (2) PLCPLCPLC (3) 紧种点紧种点紧种点紧种点紧种点紧种点点篇点紧种点紧种点 (4) 紧种点紧种点mmm?.17( 8 (5) 紧种点 紧种点PLCPLCPLCPLC (6) PLC100mm1/21/10150g 1.2.7 PLC PLCPLCPLC (1) PLCPLCPLC (2) AnalogDigitalA/DD/APLCA/DD/A (3) PLCI/O紧种点 (4) PLCPIDPLCPIDPLCPIDPID (5) PLC佼豹豇茳?紧种点鶤 9 (6) PLCPLCPLCPLCPLCPLCFA 1.2.8 PLC PLCPLCCPUI/OPLCCPUI/O(1)CPUCPUPLCPLCCPUPLCPLCCPUCPUPLCCPUCPUCPUCPUPLCPLCI/O(2) (3)I/OPLCI/OI/OPLCI/O紧种点益岸精DIDOAIAOI/O220VAC110VAC24VDC4-20mA,0-20mA0-10V,0-5V,-10-10V12bit,14bit,16bitIOIOI/OI/OCPU璑 10 (4)PLCPLC24V220VAC110VAC24VDC(5)PLCCPU(6)PLCPLCPLCPLCPLC 1.2.9 PLC PLCPLCCPU (1) PLCI/OI/O (2) PLC()RAMI/O I/OI/ORAM (3) PLCCPUI/OPLC 1.2.10 (1)LD Ladder Diagram CPU猋 11 PLC-1-1a)PLC1-1b) 度-度系示点 (2)FBD Function Black Diagram “”“”1-2a)1-2b) 度-形 (3)SFC Sequential Function Chart 1-3 度-情 鼵 12 (4)IL Instruction List CPU PLC1-41-2a) (5)ST Structured Text IEC 2.1 FX2NPLC 2.1.1 PLCPLC 2.1.2 始am1.5m/s2始m3m/s3始+m-m-m+ 紧种点鶤 13 形-度4m/s岸0.3s始4-
