摘　　要：通过对大型金属材料仓库的温度自适应控制条件,提高仓储货物的存储条件和性能。基于PLC可编程逻辑控制器,提出一种基于PLC控制的仓库温度调节系统优化设计方案。首先进行PLC可编程逻辑控制仓库温度调节基本结构设计。整个PLC可编程逻辑控制系统的体系结构可分成四个结构。设计了采用PLC可编程逻辑控制进行仓库温度调节的系统开发流程。进行仓库温度传感数据的状态模式挖掘,采用PLC控制器进行仓库的温度调节时,温度变化率、积分时间和微分时间通过线性组合的方式进行控制,进行温度调节控制算法改进。设计仓库温度调节控制系统的A/D采样电路和温度传感数据采集电路,获得温度传感输入点在PLC可编程逻辑控制器I/O映象区内的状态和数据。系统测试结果表明,设计的仓库温度调节系统具有较好的仓库温度控制调节性能,温度控制误差较小,提高了仓库存储条件。Through to the large logistics warehouse temperature adaptive control conditions, improve warehouse storage conditions and performance of the goods. Based on the PLC programmable logic controller, a warehouse temperature control system based on PLC control optimization design. First PLC programmable logic control warehouse temperature control basic structure design. Integral and differential time to control by means of linear combination, which can adjust the temperature control algorithm is improved. Design the warehouse temperature adjustment control system of the A/D sampling circuit and temperature sensor, data acquisition circuit for temperature sensor input point in PLC programmable logic controller and data I/O image area. System test results show that the design of the warehouse temperature control system has good temperature control performance, temperature control error is small, increase the warehouse storage conditions.
