电动车跷跷板系统采用华邦W78E58作为主控制器,以自制的车体为系统载体,依靠两个经过改制的舵机为动力,利用光电传感器ST168构成对路面黑线的检测,实现了对桥面的探测。同时利用角度传感器WQ36-45实现对跷跷板倾角的测量,经过A/D转换后构成反馈,对电动车平衡位置完成精确调节,控制电动车准确停在平衡点,并保持该平衡状态。该系统除了能完成题目所规定的基本要求外,还完成了液晶模块、语音模块的设计和调试,充分体现了检测、传感以及精确控制等技术在自动控制中的应用。
Electric vehicle seesaw system uses Winbond W78E58 as the main controller, with homemade vehicle body as the system carrier, relying on two modified servo as the driving force, the use of photoelectric sensor ST168 constitutes the detection of the black line on the road to achieve the bridge deck Probing. Meanwhile, the angle sensor WQ36-45 is used to measure the dip angle of the seesaw. After A / D conversion, the feedback is formed to accurately adjust the balance position of the electric vehicle and control the electric vehicle to accurately stop at the balance point and maintain the balance state. In addition to fulfilling the basic requirements stipulated in the title, the system has also completed the design and debugging of LCD modules and voice modules, fully embodying the application of the technologies of detection, sensing and precise control in automatic control.
