Lightweight detection and classification for wireless sensor networks in realistic environments[a].the 2nd Int 1 Conf on Embedded Networked Sensor Systems (SenSys 05)[C],San Diego,USA, , China. 2.South China Normal University, Guangzhou , China) Abstract: A traffic flow data acquisition system of intelligent transportation project based on Zigbee wireless networks is studied in this paper, which adopts embedded multi-tasking operating system and Zigbee 2006 Stack. The vehicle data acquisition system is composed of two parts--master module and slave module. With the help of PC software, the node parameters can be set, the controlled object can feedback the control signals and send data. The vehicle flow, vehicle speed, temperature, utilization rate of road and other data can be collected efficiently at any time, and the system temperature, the installation location, traffic flow information can be stored and handed into the database.
