某河口闸门应用钢丝绳进行启闭，传统的采用人工目视和触摸的方法可靠性差且危险。介绍了一种采用基于虚拟仪器的电磁检测技术对钢丝绳进行检测的案例，如仪器的检测原理、检测路径的设计、检测结果以及判断标准。实例证实了钢丝绳电磁虚拟检测技术的可行性。最后，基于目前日益增长的钢丝绳检测需求，以及并不广泛的检测现状，建议应该重视钢丝绳检测技术的推广及应用。

The open and close of the gate of a river were finished by steel wire ropes, whose testing was carried out by the traditional artificial methods of visual and touching methods, resulting in poor reliability and dangerous consequence. Virtual instrument-based equipment with electromagnetic technology was used for the wire rope testing. The testing principle, path design, testing results and accepting standards were introduced. The testing case proved the feasibility of the virtual electromagnetic wire rope testing technique. Finally, based on the current growing wire rope testing needs, as well as the not so satisfied testing status, a suggestion was proposed that more attention and more application promotion should be paid to wire rope testing technology.
