【摘要】 随着工业自动化水平的不断提高，动态检重变得越来越重要，因此设计了自动化流水线动态检重监控系统，该系统由动态检重、剔除、上位机监视和喷码4部分组成。PLC控制步进电机驱动输送带运送产品，PLC与称重仪表通信，实时获取产品的称重数据，PLC根据触摸屏的设定数值判断重量是否合格，若不合格则由PLC控制剔除，合格则继续运输。上位机与PLC通信，从PLC的存储区读取称重数据，并保存到SQL Server数据库中，实现产品信息的统计、查询与追溯。上位机从数据库中提取相关信息并传给喷码机，喷码机将这些内容在产品上进行喷印。目前，该系统已被应用于企业当中，提高了生产效率。更多还原

【Abstract】 With the continuous improvement of the level of industrial automation,dynamic weight inspection becomes more and more important,so the design of automatic assembly line dynamic weight inspection monitoring system,the system is composed of dynamic weight inspection,eliminating,upper computer monitoring and coding. PLC controls the stepper motor to drive the conveyor belt to transport the products. PLC communicates with the weighing instrument to obtain the weighing data of the products in real time. The PLC judges whether the weight is qualified according to the set value of the touch screen. If the weight is unqualified,it will be rejected by the PLC control. If the weight is qualified,it will continue to be transported. The upper computer communicates with PLC,reads the weighing data from the storage area of PLC,and saves it to the SQL Server database,so as to realize the statistics,query and traceability of product information. The host computer extracts the relevant information from the database and sends it to the printer,which prints these contents on the product. At present,the system has been applied to enterprises,improve the production efficiency.更多还原
