Crane hoisting monitoring using smartphone

In recent years, smart phone develops very fast, and it has been the most popular tool in daily life of the public. Smart phones, with powerful operating systems, data storage and processing function, varieties of high-performance sensors and easily data transmission when connected to network, are the good choice for structures status monitoring in some occasion. One kind of hoisting monitoring method was proposed in this paper based on smartphone and Monitoring App developed. Firstly, one monitoring App was designed and developed, which can monitor the acceleration and inclination information using MEMS sensors embedded in smartphone. Secondly, typical operation status model of crane hoisting was studied. Then one validation test of hoisting was designed and conducted to monitor the acceleration and inclination of different elements during the operation procedure of one crane. The test results show the feasibility of the crane hoisting safety monitoring method using smartphone.
