Abstract
Systems, methods and computer program code for the measurement and control of sway in load transportation systems are provided which include using Micro-Electro-Mechanical Systems (MEMS) devices to measure and control the sway of suspended loads such as loads suspended from cranes.
Claims18
A system, comprising:
- a first device, coupled to measure an acceleration of a first object suspended from a second object, the first device generating a first signal representing the acceleration of the first object;
- a second device, coupled to measure an acceleration of the second object, the second device generating a second signal representing the acceleration of the second object;
- and
- a processor in communication with the first and second devices, the processor operable to determine a sway of the first object with respect to the second object based at least in part on the first and second signals, the sway representing a relative displacement of the first object with respect to the second object.
1 more element
A computer-readable medium having instructions thereon, wherein said instructions, when executed by a processor, cause the processor to:
- receive a first signal representing an acceleration of a first object from a first device coupled to the first object;
- receive a second signal representing an acceleration of a second object from a second device coupled to a second object, the second object suspended from the first object;
- and
- determine, based at least in part on the first and second signals, a sway of the second object with respect to the first object, the sway representing a relative displacement of the second object with respect to the first object.
