At present, the elevator control system mainly has three kinds of control mode: following the circuit control system (the early installation of elevator multiposition relay control system), the control system, the microcomputer control system of FPGA/CPLD. Relay control system due to high failure rate, poor reliability, control mode is not flexible and disadvantages such as big power consumption, has gradually been eliminated, though the microcomputer control system in intelligent control has the strong function, but also has the perturbation resistance is poor, the system design is complex, general maintenance personnel are difficult to grasp its maintenance technology, defect. FPGA/CPLD control system because of high reliability, convenient operation and maintenance, strong anti-interference, design and commissioning period shorter, advantages of paid more attention to by people, has become in the elevator control system used in most of the control method, is also widely used in the technical transformati
