摘要
针对目前机场跑道摩擦系数车测量控制系统落后、上位机操作繁琐和数据传输不稳定的问题,采用西门子1200PLC作为下位机控制系统和基于C#开发的Winform上位机可视化界面,通过TCP/IP协议作为二者数据传输的桥梁。采用多线程设计提高数据传输的效率和稳定性,采用巴特沃斯低通滤波器滤除原始数据中的干扰信号。该测量系统使用方便,设置完成后对同一路面进行多次摩擦系数测量实验,测量结果重复性好,平均摩擦系数值标准差在±0.02范围内,满足民航特种设备相关要求。
Aiming at the problems that the backwardness of the airport surface friction tester’s measurement and control system,the cumbersome operation of the upper computer,and the unstable data transmission,Siemens 1200 PLC is used as the lower computer control system and the Winform upper computer visual interface developed based on C#.Through TCP/IP protocol as a bridge between the two data transmission.Multi-threaded design is used to improve the efficiency and stability of data transmission,and Butterworth low-pass filter is used to filter out interference signals in the original data.The measurement system is easy to use.After the setting is completed,multiple friction coefficient measurement experiments are performed on the same road surface.The measurement results have good repeatability and the standard deviation of the average friction coefficient value is within ±0.02,which meets the relevant requirements of civil aviation special equipment.
