摘要
为了实现食品检测的自动化,设计了与仪器配套的数据通信及分析软件系统.软件采用RS232通信技术和VB 6.0、SQL Sever2000数据库语言研制,用最小二乘法拟合回归方程求待测溶液的浓度,并根据相关系数r检验曲线的拟合效果.实验表明,通信软件可以设置测试参数,能实时接收并保存测试数据,能按要求处理数据并以图形及表格形式显示处理结果,还能查询、修改及重测数据.通信软件界面友好、简单易用、能屏蔽和纠正用户的误操作、图形显示清晰准确,数据传输、处理的准确率达到100%.
In order to realize the automation of food testing,the data communication and analysis software system of the instrument is designed.RS232 communication technology and VB 6.0,SQL Sever 2000 database language are used to develop the software.The solution concentration is solved by regression equation,and the curve fitting result is examined by correlation coefficient r.Experiments show that the communication software can set test parameters,can receive and save the test data in real time,can display the results in graphical and tabular form,and can query,modify and re-test data.Communication software is easy to use and can shield and correct the user＇s misuse.The graphical display is clear and accurate,and the accuracy rate of data transmission and processing reaches 100%.
