采用串级结构的溶液浓度——流量控制器的设计

Serial Structured Liquid Concentration Flow Controller

介绍一种用于自来水处理系统的溶液浓度———流量控制器的设计.该控制器以单片机为主控机,运用串级控制实现对大滞后、大时延对象的控制.在软件设计上运用模块化设计思想,采用C语言编制单片机应用程序.目前该控制器的各项性能指标经测试达到用户要求,并具有较强的现场适应能力.

This paper introduces a flow controller designed for monitoring the solution density of the water treated system. It uses SCM as the primary computer, and through the series control it realizes to control those objects having the nature of large time-delay in the sense of software designs,it uses the thought of modularization and adopts C language for the application program of SCM. The controller’s all characteristics now have met the requirements of users it has the powerful capability of adapting field.
