Design and realization of Modular MEMS-based Attitude measurement and control system based Wireless Sensor Networks

摘要

The modular platform system in this paper consists of a series of modularized MEMS subsystems, including central control unit, MEMS attitude measurement unit, environment unit, flight measurement and control unit, time control unit, impact vibration measurement unit and other auxiliary modular units. The key of the system is the MEMS attitude measurement unit, which can resolve the real time attitude information of the carrier. The system platform chooses different sensors and units according to various circumstances and implements data collection, fusion and solution through the central processing module. By means of carrying distinct units, system platform can constitute many measurement control systems, such as Micro wireless attitude determination system, MAV flight data recorder, MAV flight control system and PHM (prognostic and health management). With application of MEMS, the system in this paper is high-efficient, low-weighted, simple-structured, high-reliable and even can respond in a short time. In view of these merits, the system can be applied in many kinds of attitude measurement and control system.
