摘要
针对传统桥梁振动频率测量系统中存在的测量精度低、速度慢、可靠性差的缺点,提出了一项新型的基于μC/OS_Ⅱ振弦式传感器频率测量方案.该方案引入了一种高效的等精度测频技术,并率先实现了μC/OS_Ⅱ操作系统与频率测量体系的实时结合.多次现场测试表明,系统测量的精度、速度和可靠性明显优于传统测频系统.
To overcome the shortcoming of the traditional measuring vibrating frequency system for the bridge security in precision, acceleraion and reliability aspects, a new measuring project based on the μC/OS-Ⅱ operation system is proposed. The project adopts a equally accurate measuring frequency technology, which is the first combination with μC/OS-Ⅱ operation system and equally accurate technology until this time. It has proved, in practice, that the system performance is better prior than before.
