According to the characteristic of running tubings, this measurer adopted an indirect method to realize intelligent online measurement of tubing length. Based on 89C51 single\|chip computer, the linear displacement of the wire rope was turned into pulses by the photoelectric sensor mounted in front of the drum, then the pulses were processed by computer and displayed in digital form. A discriminator was used for effective control of the measurement in consideration of the complexity of running tubings. In order to raise the measuring accuracy, a mathematical model was established after thinking over the deformation of the wire rope of lifting gear. The hardware and software were designed on basis of this method. The result of the simulation test showed that this measurer run well with high accuracy.
