摘要
某型船用载货电梯采用PLC控制。PLC单独使用时,在控制装置在使用过程中存在一些不足,会出现运行不稳定、能耗大、噪音大等问题。通过加装变频器对某型船的PLC单独控制的系统进行系统的升级改造,介绍了基于PLC与变频器的电梯控制系统硬件组成方案及逻辑控制程序。仿真结果表明加装变频器后,电梯故障率降低,提高了电梯运行的安全性和可靠性。
PLC controller is used in a marine cargo elevator. There are some shortcomings in the use of the PLC, such as running instability, large energy consumes, high noise and so on. The transducer is equipped for the system to upgrade PLC control system. Hardware and logic control program of elevator＇s control system are introduced based on PLC and transducer. Simulation results show that the malfunction of the elevator with transducer becomes low, and safer and reliabler.
