摘要
本文设计了一种基于超声波测距技术的小型船舶预警系统。超声波是一种机械波,在传播过程中具有方向性强,能量集中,不易受干扰等优点,因而广泛应用于测距领域。本文以FPGA作为主控芯片,对声速进行温度补偿,提高了测量精度,使船舶可以提前对障碍物进行预警。
In this paper,an warning system for small ships based on ultrasonic ranging technology is designed.Ultrasonic waves are mechanical waves that have strong directionality,concentrated energy,and are not susceptible to interference during propagation.They are widely used in the field of ranging.In this paper,FPGA is used as the main control chip,and the sound speed is compensated by temperature,which improves the measurement accuracy and enables the ship to warn the obstacles in advance.
