摘要
本文对一款基于PLC的机场行李分拣控制系统予以设计与实现。此系统将西门子S7-200系列PLC当作核心控制器，联合RFID技术、重量传感器、光电传感器以及液压推杆等硬件装置，达成了行李的自动辨别、重量查验、分拣执行以及流量监控等功用。借助STEP7-Micro/WIN编程软件，系统达成了行李分拣的自动化控制逻辑，而且能够支持手动/自动模式的转换，从而灵活地满足不同场景的需求。MCGS监控软件的运用，进一步提高了系统的可视化管理程度，实现了实时监测、参数设定、故障警报以及数据统计等功能。历经硬件调试与软件调试后，系统各模块的功能得到了充分的验证，实物测试展现出系统在实际运转中的高效性与精确性。结果显示，该系统可显著提高机场行李处理的效率与服务品质，降低人工成本与出错率，为机场的智能化运作提供了强有力的支撑。
