Reconstruction of MEMS accelerometer outputs in mobile fields by using Allan variance

Nowadays, a growing interest has been accorded to wireless communication in different fields especially in electrical domains. Due to the electromagnetic, Doppler and phases problems, the using of wireless communication in electrical motors is restricted. This paper presents primary studies which highlight the importance of using wireless sensors inside motor and pointed out a number of problems related to wire mechanical connection as vibrations and sliding. In order to solve this problem, a redundant network of distributed accelerators is used. Indeed; the proposed method allows predicting of reference signal. The evaluation of signal is achieved by using Allan variance technique and then an optimization method is applied to minimize errors between different signals. Many experimental tests have been done and Results are also interpreted and commented.
