脱粒滚筒圆柱度数据采集系统设计——基于VB串口通信

Threshing Drum Cylindrical Degree Data Acquisition System Design—Based on VB Serial Communication

针对稻麦收获机脱粒滚筒圆柱度检测效率低、误差大的现状,提出了一种基于VB串口通信的脱粒滚筒圆柱度数据采集系统设计方法,首先通过程序实现激光位移传感器与上位机的通信,激光传感器再对脱粒滚筒外圆柱面进行数据采集,最后对采集的数据进行处理。实验表明:该系统能在5min以内完成数据的采集、存储和分析,采集到的数据与真实值的误差在±0.9mm范围内,采集系统界面简洁、操作方便,应用范围十分广泛。

In order to solve the problem of low efficiency and great error in cylindrical degree detection,this paper puts forward a method of threshing drum cylindrical degree data acquisition system design based on VB serial communication,first the system realize the laser displacement sensor and host computer communication through program,then the laser displacement sensor collect the data of outer cylinder,and finally deal with the data. Experiments show that the system can complete the acquisition,storage and analysis of data within 5min,the error of collected data and real value is in the range of ± 0. 9 mm,the system has a simple interface,convenient operation,and wide range of application.
