Distributed Optical Sensor Network with Self-monitoring Mechanism for Accurate Indoor Location and Coordinate Measurement

摘要：

　　In order to provide accurate and robust indoor location service for large-scale mechanical manufacturing, a sensor network consisting of laser transmitters and optical receivers is proposed in a distributed framework.Geometric model described by rotating plane equations is established, re ceivers location algorithm is achieved by utilizing intersection constraint of multiple laser planes form different transmitters.A self-monitoring mechanism for sensor network is also presented by introducing redundant fixed receivers as reference.Experiment has shown that the measuring accu racy of a minimal sensor network is better than 0.2mm and self-monitoring mechanism can effec tively guarantee the accuracy of the measurement results.
