| 英文摘要: |
| 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 lowpass 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. |
