【Abstract】 A method that can detect the breaking point location of cable by using low pressure reflection is introduced, and a control system through 89C52 SCM is set up.By sending low pressure impulse and receiving it,the location of breaking point can be detected automatically. The system structure is simple and its application effect is good.更多还原
