摘要
RFID(Radio Frequency Identification,无线射频识别技术)广泛应用于智能交通,由于高速公路中汽车车速的不断提高,能否在有效场区内完成对RFID标签的读写需要大量的测试。采用STC89C51单片机设计的模拟测速装置能够准确模拟汽车通过RFID读卡器有效场区的时间,降低RFID的开发周期和成本。
Radio Frequency Identification（RFID） is widely used in intelligent transportation, due to the continuous speed increase of the car on highway, whether the RFID tag literacy can be finished in the effective field requires a lot of tests. The simulated speed measurement device based on STC89C5 microcontroller can accurately simulate the time of car going through the effective field of RFID reader, which can reduce the development cycle and cost of RFID.
