摘要
介绍了以可编程序控制器PLC226,单片机89C51和操作员面板OP07为组合处理单元的配料称重控制系统的组成原理,给出了系统的主要程序设计流程。实践表明:该系统运行正确可靠且具有硬件结构简单和成本低廉的特点。
The configure and its principle of a burden charging and weighing control system are presented. The combined processing unit of this system mainly consist of S7-PLC226, AT89C51 and OP07. The main program diagram are given in this paper. The practice shows that this system with a simple structure and low cost runs correctly and reliably.
