为了实现自动冲饮机展示自动控制技术及多种传动方式的要求,对控制系统的硬件和软件设计进行了深入的讨论;在分析出系统的控制方式为通断控制以后,提出采用可编程逻辑控制器作为系统的控制核心,确定了控制系统硬件结构,给出了软件流程图,并采用模块化方法编写了可编程逻辑控制器程序.在控制系统中增加了客户机和服务器,并利用网络通讯技术和串行通讯技术实现了一种下位机-客户机-服务器的三级监控系统设计方案,现场运行情况良好.
In order to achieve the automatic brewing machine display automatic control technology and a variety of transmission requirements, the control system hardware and software design conducted in-depth discussion; after the analysis of the system control for the on-off control, the use of programmable logic The controller as the control core of the system determines the hardware structure of the control system, gives the software flow chart, and uses the modular method to write the programmable logic controller program. Adds the client and the server in the control system, and utilizes the network Communication technology and serial communication technology to achieve a lower computer - client - server monitoring system design of the three-tier, field operation in good condition.
