水果综合分选机称重模块的设计与实现

Design and implementation of weighing module for fruit integrative grader

为满足水果外观品质和质量综合分选的实际需要,设计了水果机器视觉质量综合分选机的称重模块。通过受力分析得出了水果质量的理论计算公式,给出了水果同步称重过程的实现方法。通过对质量不同的苹果进行实测标定,得出了等效质量w与其A/D转换值之间的关系式,并进行了试验验证。试验结果表明,所设计的称重模块可以与水果机器视觉分选机配合,对水果进行外观品质和质量的检测,称重精度约为2%。

In order to satisfy the demand of fruit integrative grading by appearance quality and weight,a weighing module for fruit integrative grader was designed.The theoretical calculation formula of fruit weight was educed with the method of force analysis,and the implementing method of fruit synchronous weighing process was presented.A functional relationship equation between the equivalent mass of the fruit(w)and the A/D conversion result was achieved and calibrated with apples,and it was testified with other ap...
