Design of Optical Fiber SPR Sensor Network Based on 89C52 Single-chip

In order to realize the data acquisition,processing,communication and test of underground ulti-channel gas concentration,the optical fiber SPR sensor network based on the single-chip device is deigned.Aiming at the single-chip device,this network combines optical switching devices with serial devices.In rder to achieve multi-channel communications,and taking the mechanical optical switch with low loss and high calability into account,so 32 groups mechanical optical switches are used;89C52 single-chip controls the optial switch to realize 32 groups cycle test.This single-chip has high-capacity and high-speed characteristics;In adition,the total program of system operation is written,the gas concentration alarm is simulated by LABVIEW.
