针对目前国内外糖厂“按质论价”糖料收购系统存在的问题,为弥补二次旋光法(手工检测法)检测糖料含糖量速度慢、操作繁杂,近红外分析仪设备价格昂贵等不足,给出了一种新型的“按质论价”糖料收购系统。该系统由可编程控制器(PLC)进行控制,由单片机实现数据采集,并把自动电位滴定仪和PC机相结合,实现了自动在线检测糖料含糖量的功能;并运用LabVIEW实现了人机对话交互式平台。该系统能快速检测糖料含糖量,且操作简单,实验结果证明了其有效性。
In view of the problems existing in the domestic and foreign sugar mills “Quality Price ” sugar purchase system, in order to make up for the second rotation method (manual detection method) to detect the sugar content of sugar slowly and the operation is complicated, the near infrared analyzer equipment Expensive and other shortcomings, given a new type of “quality by the price ” sugar acquisition system. The system is controlled by a programmable logic controller (PLC), which realizes the data acquisition by SCM. The automatic titrator and PC are combined to realize the function of automatically measuring the sugar content of sugar. Machine dialogue interactive platform. The system can quickly detect the sugar content of sugar, and the operation is simple, the experimental results prove its effectiveness.
