At the same time, along with automated technology fast development, also enormously promoted the elevator control technology progress, the massive advanced controls technology applies to the elevator group control system, enables the elevator group control system the control characteristic to have the very big improvement. In view of present this present situation, the present paper take two five elevators as the design object, has conducted the more thorough analysis research to the elevator group control question, proposed some own understanding and the view, designed a set of PLC double elevator coordinated control system.2 Control systems hardware design This system is mainly the exchange frequency conversion velocity modulation system which by PLC, the frequency changer, the control box, the monitor, the electric motor is posed (Variable Voltage Variable Frequency, is called VVVF). Controls two elevators movements through PLC the way, may omit between two programmable controllers the mutual correspondences, thus causes the control system the reliability to be higher, the structure appears pact. This system hardware diagram like chart 1 shows. May see from chart 1, this system mainly is posed by two parts, elevator controls the logical gate realizes by PLC. Studies the elevator through the analysis the actual movement situation and the control rule, thus designs sends out a set of double elevators linkages control procedure, enables PLC to be able to control two elevatorsthe movement operations. The elevator velocity modulation partial selects the high performance the vector control frequency changer, matches (encoder) surveys the mouse cage type electric motor by the pulse generator the rotational speed, thus constitutes the electrical machinery the closed loop vector control system, the realization mouse cage type electric motor exchange frequency conversion velocity modulation (Variable Voltage Variable Frequency, is called VVVF) to move.Chart 1 PLC double elevator coordinated control system hardware diagramPLC first receives shouts the ladder signal, the even level signal from the elevator, then acts according to these input signals the condition, through its interior a series of plex control procedure, has the foreword to each kind of signal logical relations to carry on processing, finally controls the electrical machinery, the frequency changer and each kind of monitor to the direct current gate at the right moment sends out the switch quantity control signal, to two elevators implementations group control. In elevator control system, because the elevator control belongs to the random control, between between between each kind of input signal, output signal as well as input signal and output signal connection very strong, the logical relations processes is extremely plex, this gives PLC the programming to bring the very great difficulty. In a sense, PLC programming level height on decision overall system
