摘要
根据超声波测距原理设计了一款倒车雷达系统,采用EASYARM2103开发板中的32位ARM处理器LPC2103作为数字电路处理器,超声测距采用凌阳公司的超声波测距模组V2.0,液晶屏采用OCM12864-3,开发软件用的是ADS1.2.系统设计采用了模块化的设计思想,把系统分为超声波测距部分和液晶显示部分,这样不仅简化了调试的工作量,同时方便程序的维护和升级.倒车雷达测距范围为140 cm到40 cm,40 cm以下为盲区,测量误差为5 cm.
The back-draft radar was designed by ultrasonic principle. The 32 binary elements ARM LPC2103 of the demo board EASYARM2]03 is utilized as digital circuit processor. Ultrasonic ranging module V2. 0 produced by Ling yang Corporation is utilized as ranging system. OCMJ2864-3 is utilized as LCD and the developing software is ADS1.2. The idea of modularization has been used to divide the system into ultrasonic measuring part and LCD part. In this way, the work has been simplified and the procedure＇s maintenance and promotion have also been easily conducted. The distance-measuring of back-draft radar ranges from 140 cm to 40 cm, the blind zone is under 40cm and the measurement error is 5 cm.
