Design and realization of asymmetrical 3×3 optical interference accelerometer wireless network

In order to satisfy the requirements of real-time, high accuracy and the realization of network of fiberoptic sensor seismic accelerometer, this study constructs a Zigbee wireless sensor network which is based on non-systemmetric 3×3 optical interferometric acceletometer, using CC2430 RF chip, S3C2410 and fiber-optic sensor of asymmetric 3×3 structure to complete the design of sensor nodes and coordinator node. This research introduces Zigbee networking technology, analyses the software and hardware design of network terminal, and has tested the the network node. The testing result shows that the network node has capability of high sensitivity and reliable data transmission, and that test signal from 200Hz to 1kHz can be right demodulated on real-time by network node. The wireless network provides a feasible program for realization of network of the optical interference accelerometer.
