交通量数据采集仪的软件设计

IThis paper introduces a new traffic data collection system, which based on ARM9 microprocessor，GPRS and magneto resistive sensor. The system is composed of Flash, LCD touch screen, magneto resistive sensor, GPRS wireless transmission module and other peripherals. Magneto resistive sensor is studied and used to detect traffic data, such as speed and type; besides, GUI windows is designed, so that users could control and operate conveniently. The system is superior in many aspects, for example its practicability, stability and efficiency. The system discussed in this paper would make a positive contribution in intelligent traffic system.
