Design of remote data acquisition system of passenger flow based on GPRS

According to acquisition data of passenger flow relay on artificial and transporting of unreal-time, this paper introduces system of acquisition data of passenger flow base on GPRS by infrared transducer and pressure transducer. Elaborate hardware scheme design of embedded microprocessor in ARM7 core, implement transporting data of passenger flow to data terminal base on GPRS in time and exact, it is provided a reliable basis for real-time scheduling in public transportation.
