Aiming at two major problems in object flow information collection that multi-point monitoring and object type distinguishing can’t be realized

a system for object flow information monitoring based on WSNs is designed.The system is composed of the monitoring nodes

the base station node and the upper.The monitoring nodes send the monitored data to the base station node through a chain topology structure.Then the data are sent to the upper computer for statistics and data analysis.This system can realize multi-point object flow monitoring and object type distinguishing without any auxiliary aided labeling.
