Research On Monitoring System For Lane Departure Of Bus Based On Zigbee

Research on monitoring system for lane departure of bus based on ZigBee has very important practical significance and academic value, as improving the security of public, ZigBee wireless communication technology not only avoiding the cumbersome wiring, but also promoting the intelligent development of public transportation.The main research contents are as follows:1. Design bus communication network based on the ZigBee according to features and protocol architecture of ZigBee, requirements advanced public transportation, using complementary advantages of the Internet and ZigBee in transmission distance.2. Determine the directional and positional parameters for the current lane of bus by combining the lane edge information from collect image with CCD parameters. According to the specific application requirements of bus, designed appropriate departure warning geometric model and decision-making model.3. Preprocess the image with G language in the light of the characteristics of the lane image data and needing to achieve the effect, develop steps to extract the image straight by studying the principle, the nature and the implementation process of Hough and extract the lane boundary by Hough.4. Develop the terminal node schematic using CC2530RF transceiver between the the car node and routing node, ZigBee data transmit by real networking experience, design the man-machine interface to video monitor.Camera installed in the bus to real-time acquire road image, and transmitted wirelessly with ZigBee, preprocessed the image with G language to get the parameters of lane edge. Extracted the lane edge by Hough fitting. According to the model of lane departure warning, realized the alarm function and video surveillance.
