Real-time Acquisition Method of Fixed-point Mapping Data Based on Optical Fiber Communication Network
Fixed point surveying data is often limited by communication distance,transmission rate,and data security,resulting in a small amount of data transmitted per unit cycle.Therefore,a real-time collection method for fixed point surveying data based on fiber optic communication network is designed.Sparse representation of fixed-point surveying data for more effective data compression perception.Construct an observation matrix for fixed-point surveying data and transmit this data in real-time.Finally,establish a compressed sensing data collection framework to achieve real-time collection of fixed-point surveying data.The experimental results show that the real-time data collection method for fixed-point surveying and mapping based on fiber optic communication network designed in this paper can transmit a large amount of data per unit cy-cle,with a maximum of 49GB,proving that the data output of this method is stable and the data collection effect is better.
