盾构机后配套多带式输送机PLC控制系统设计

Design of PLC Control System For Multiple Conveyors After Shield Machine

基于盾构机后配套输送机具有距离长、设备分散、维护不便等特点,提出以西门子公司S7-1200系列PLC为核心的设计方案。设计给出网络结构,列明主要硬件配置,通过采用多个CPU,并结合总线通信方式实现多带式输送机控制。经实际运行表明,该系统运行可靠、维护方便,有效地提高了生产效率。

Belt conveyors after shield machine are long distance,scattered equipment and inconvenient maintenance.According to this situation,a design based on Siemens S7-1200 series PLC is proposed.This design gives the network structure and a list of the main hardware.Multiple belt conveyors are controlled by using multiple CPUs and bus communication.The actual operation shows that the system is reliable operation,easy to maintenance,it can improve production efficiency.
