基于虚拟仪器的蚕丝细度连续测量控制系统

 以美国国家仪器(NI)公司的虚拟仪器为架构,在LabVIEW开发环境下,结合PIC单片机开发了一套蚕丝细度连续测量控制系统。这种系统能够自动检测蚕丝在缫丝过程中的断头,控制卷绕装置的运行,而且能通过霍尔传感器和PIC单片机实现蚕丝在卷绕过程中渐进式的推进,解决了蚕丝在连续测量过程中断头以及测量结果与称重法结果之间难以对比的问题。实验结果表明该控制系统可靠性较好,抗干扰能力较强。

Controlling system for continuous testing apparatus of fineness of cocoon silk based on virtual instrument

Combining with the PIC microcontroller,a controlling system for continuous testing apparatus of the fineness of cocoon silk was developed under the framework of virtual instrument from American National Instruments Company(NI) in LabVIEW developing environment.The system can automatically detect the end breaking of cocoon silk when reeling,control the processing of winding device,and also gradually push the bave during reeling by Hall sensor and PIC microcontroller.The problems of cocoon silk breaking while testing and the difficulties in comparing results between testing and weighting methods were resolved by the system.Experimental results indicated that the reliability and anti-jamming ability of the controlling system were good.
