摘要
集成无线射频识别(RFID)技术和传感器技术,设计了一种速度传感标签,用于高速公路机动车行驶速度的实时监测,并为驾驶人员提供预警功能。详细介绍了传感标签的硬件和软件设计。实验表明,传感标签能接收联网读写器传来的前方路段限速信息并以数码显示,而当机动车行驶速度超过限速要求时,标签能采集机动车实际速度,以语音方式提醒驾驶人员。
Combination RFID(radio frequency identification) and sensing technology,a sensor-tag using in real-time monitoring the actual speed for vehicles and supporting early warning for the vehicle driver is propsed.The hardware and software of the sensor-tag is analyzed in detail.Experimental results show that it can accept and display the limit seed information of the road ahead transmitted by readers connected with network,when the vehicle drives over the limited speed, the system can acquire vehicle speed accurately and voice alarm to the driver.
