摘要
针对现有离子源调节装置精度低,操作繁琐的问题,设计了一种多维自动调节装置的控制系统。采用Labview编写上位机控制界面,通过串口实现电机选择,结合直线型加减速算法对步进电机进行开环控制,以实现放电针和样品的精确定位。实验证明,该系统具有操作简便和精度高的特点,有效提高了工作效率。
The existing Ionization source adjuster has low accuracy and complicated operation.In response to these issues,a control system of multidimensional self- regulating device was designed.To realize the accurate positioning ofspraypointand sample,thesteppermotorwasselected and open- loop controlled by Serialcommunication based on PC programed by Lab View,combined with liner acceleration- deceleration algorithm.It hasbeenfound thatthesystemhasthemeritofeasyoperating and highaccuracy,and improvestheworking efficiencyeffectively.
