摘要
船舶在水中航行,经常会涉及到对周围物体和船只的测量,以便及时发现危险,避免碰撞事故的发生。超声波是自然界中的一种机械波,超声波在传播时,具有传播方向性强,传播能量强,而且传播过程不容易被干扰,传播能量衰减较小,传播较远的优点。因此,可以将超声波方便地应用在船舶测距系统中。本文基于单片机,对船舶的超声波测距系统进行设计和研究,系统可以实现对船舶周围物体距离和方向的测量。
While the ship sailing in water, it often involves with the distance measurement of the surrounding mechanical energy, the objects wave in spread and ships, in order to nature, ultrasonic has energy is not easy to be discover a series the risk, avoid collision. of advantages of strong d Ultrasonic is a kind of lrectlvlty, interfered and damped during the transmission strong spread and can travel long distances. Therefore, ultrasonic can be easily applied in ship distance measurement system. In this paper ultrasonic distance measurement system on the ship is designed and researched based on micro control unit, the system can realize the measurement of the distance and direction of the object around the ship.
