The embodiment of the invention provides a system and method for detecting rope unwinding length of a winch and a crane, and belongs to the technical field of engineering machinery. The system for detecting rope unwinding length of the winch comprises an image acquisition device and a controller, wherein the image acquisition device is used for shooting signal data of a steel wire rope winding a winding drum; and the controller is connected with the image acquisition device and is used for determining the unwinding length of the steel wire rope according to the signal data of the steel wire rope. The signal data of the steel wire rope on the winding drum of the winch is collected through the image acquisition device, the rope unwinding length of the steel wire rope is obtained through calculation, and then the calculation precision of the load ground clearance and quality of the crane is improved.

    本发明实施例提供一种卷扬的放绳长度检测系统、方法及起重机,属于工程机械技术领域。所述卷扬的放绳长度检测系统包括:图像采集装置,用于拍摄缠绕于卷筒上的钢丝绳信号数据;控制器,与所述图像采集装置连接,用于根据所述钢丝绳信号数据确定所述钢丝绳的放绳长度。通过图像采集装置采集卷扬卷筒上的钢丝绳信号数据,计算获得钢丝绳的放绳长度,进而提高起重机载荷离地高度和质量的计算精度。
