摘要
为实时掌握小型多功能底盘的运动速度,提高机器的作业效率和质量,设计了一套测速系统。该系统以STC89C51单片机和外围硬件电路构成硬件为平台,采用串口通信技术、C语言软件编程技术等,将测得的转速在LED数码管上显示出来,系统抗干扰能力强且能耗低。测试结果表明,该系统速度测量精度高,平均精度可达98.2%,能够满足系统设计的测速要求。
In order to find out the real velocity of the small multifunctional chassis so as to improve the work efficiency and quality, a set of measurement system was designed. The system uses STC89C51 microcontroller and peripheral hardware circuit as hardware platform and employs the serial communication technology and C language software programming techniques. The velocity measured was displayed on the LED digital tube. The system has strong anti-interference capacity and ultra low power consumption. The experimental results show that this system is precise in speed measuring, and the average accuracy is 98. 2%, which can meet the requirements on the design speed of the system.
