Some Problems Analysis and Discussion of Real-time Position with Continuous Operation Reference System

In the construction scheme of auto-announce system of bus based on real-time position,the Bluetooth module(ROK101008) is used to successfully solve the induction and recognition of the vehicle subsystem to the site subsystem,realize the automatic position and phonological station reporting of bus,adapt and improve the normalization and the automation of bus s management.

The paper introduces Realization way of a long baseline acoustic positioning system for multi-targets, System have high resolution and flexible positioning way, can carry out real-time positioning, monitoring and management by map to multi-targets, The paper else introduces system’s design, component, key arithmetic way and test in sea.
