基于数据比对的称重罐漏料监控系统的开发

范祖禹的《论语说》既具有宋代理学《论语》学的一般特色，不但重视对《四书》的融贯性解读，而且倡导立诚成圣，着力阐发人性论和“礼”与“理”的关系；也有自己的鲜明个性，不但注重引史证《论》，而且重视对经世之学的抉发，因此在宋代《论语》学史上占有一席之地。

Development of Weighing Tank Leakage Monitoring System Based on Data Comparison

In order to avoid weighing tank leakage accidents and to assure the safety of spice formula, PLC controller was adopted to collect the starting weight of each tank. On the basis of the said data, data comparison module of real-time weight was developed with the help of STEP 7 software. When the difference value of real-time weight and starting weight exceeds the set threshold value, the module will automatically output the alarming signal. On the WinCC developing platform, this paper designed a HMI human-computer interaction interface to display weight data of each tank and the alarming information intensively. Since put into operation, the system has achieved good effects. It can achieve real time monitoring of weight change of the weighing tanks and timely warn the valve leakage, thus effectively preventing the possible formula quality accidents, reducing the waste of raw materials and assuring the inner quality of silk-making products.
