| Abstract: | The Principle of aquisition of hook shift and some relevant parameters for drilling is introduced. The methods for measuring hook shift with the photoelectric sensor on the pulley or with the magnetelectric sensor on the drawworks are descrived. The algorithm for real-time computer aquistion of the pulse signal is given. Field test proved that the photoelectric sensor oh the pulley is more accurate in measurement, but is complicated in machining and assembling. The magnetoelectric sensor on the drawworks is easy to install and simple in structure and has a long life. The measurement accuracy can be greatly improved with the use of a special algorighm. |
