Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] When the crane load is raised and lowered, the signal of the weight sensor changes greatly in a short period of time, that is, it is a high-frequency signal at this time, and the specific frequency is related to the lifting speed.
[0027] When the load is suspended in the air, the signal amplitude changes little, and the fluctuation period is very long, that is, it is a low-frequency signal at this time. According to the gravitational acceleration and the swing radius, the swing period, that is, the fluctuation period of the signal, can be calculated, and the swing frequency is below about 0.3HZ. in,
[0028] Osci...
