Now, Internal and external vehicles are artificially queried and identified by a specially-assigned person in most of schools and enterprises, so the workload of vehicle management is very heavy, what’s more the vehicles information can not be effectively preserved. So it is not convenient for vehicles access query in the furture. Using RFID intelligent sensor network technology, the intelligent monitoring and identifing of vehicles access was realized and vehicles access was better controlled. The system can provide real-time effective data for enterprises management. Through the unit LAN system, the remote transmission and perservation of the vehicle information and photos were completed, so the network management was realized and the information can be conveniently queried in the future.
