Research on Monitoring Force of Steel Wire Rope of Grab Dredger Base on Wireless Sensing

The article research on intelligent grab dredger. Work force mechanical model of steel wire is established during dredging Grab's flat digging working. Then, the theoretical calculation on stress of the steel wire is available. It's easy to get the result of dredging Grab's steel wire. Meanwhile, a way is put forward about changing the rotating shaft torque to the force of steel wire, which is based on detection of wireless sensor network technology in grab dredger's hoist. The ideal result on Real-time display of the curves of closing hoist and hoist rope's stress. The test result of real-time monitoring show that the theoretical calculation on stress of the steel wire is consistent with the test result of real-time monitoring, which provide the basis on the application of real-time monitoring of wireless sensor technology in the grab dredger's steel wire's stress.
