基于SOPC高精度超声波测距系统研究与实现
资料介绍
为了解决超声波测距精度不高的问题,文章介绍了一种基于SOPC高精度超声波测距系统。采用互相关法测距算法,以SOPC系统作为信号处理和控制的核心。使用QuartusⅡ和SOPC Builder完成对SOPC系统的定制。系统还设计了温度补偿电路和自动增益电路。测试结果表明,此系统测距相对误差可以达到0.1%,同时抗干扰效果强,具有在线升级功能,有一定的实用性。
In order to solve the problem of low precision of ultrasonic ranging,a high precision ultrasonic ranging system is introduced based on SOPC.Using cross-correlation method,the SOPC system is the core of signal processing and control.Customization of SOPC system using Quartus II and SOPC Builder.The system also makes design the temperature compensation circuit and the automatic gain circuit.Test results show that the relative error of the system may reach 0.1%,and the anti-interference ability is strong,can achieve online upgrade and has certain practical value.
