Lifting Capacity Detection System of Tower Crane Based on LabVIEW

Abstract:

The real-time acquisition of lifting capacity is a common problem in the course of tower crane work. Its an accurate and reliable method to use shaft pin type load cell to convert weight to electrical signal which is detected and processed in practical. Using STC89C52 as the core processor, the hardware consists of signal section modulating circuit, acquisition circuit and communication circuit; C language and LabVIEW graphical language are used to develop the system, including A/D conversion, data transmission, reduction and linear compensation, section control and data storage. As shown in the experimental results, the system improves the detection accuracy of the lifting capacity. It has friendly man-machine interface and is easy to analyse and process subsequently.
