摘要
为了提高超声波的测量精度,利用FPGA技术设计一款高精度超声波测距仪。利用QuartusⅡ软件在一片高密度的可编程逻辑门列阵(FPGA)上,设计基于So PC的硬件系统平台,并利用NiosⅡEDS开发软件开发测量仪的软件系统。利用FPGA内部的硬件资源设计高速度的超声波控制器,采用温度传感器DS18B20测量环境温度,并利用温度修正超声波传播速度。测试表明,利用该方案设计的超声波测距仪具有较高的距离测量精度,有一定的实用推广价值。
In order to improve the measurement accuracy, a high-precision ultrasonic range finder was designed based onfield programmable gate array （FPGA） technology. The hardware system platform based on SoPC was designed on a high-densityFPGA by using Quartus Ⅱ software. The Nios II EDS development software is used to develop the software system of the rangefinder. The hardware resource inside FPGA is adopted to design the high-speed ultrasonic controller. The temperature sensorDS18B20 is employed to measure the environment temperature. The temperature is used to correct the ultrasonic propagation ve-locity. The test results show that the ultrasonic range finder has high range measuring precision, and a certain practical promo-tion value.
