数字PID控制在乳粉干燥自动化系统中的开发与应用

A Machine Applies Of Arithmetic Figure PID Control In The Milk Automation That Powder Is Dry Control

随着计算机技术的不断普及,用计算机控制生产过程已越来越引起各行各业的重视。单片机作为最典型的嵌入式系统,已被广泛的应用到各种类型的工业控制中。将单片计算机控制技术应用于生产线上,实现生产过程的自动控制,同时通过对工业现场的生产情况进行监控,达到加强管理、提高产品质量、提高生产效率、降低劳动强度的目的,是当前企业生产控制管理的发展趋势。在乳粉生产过程中乳粉干燥是乳粉生产中一个重要工序,它直接关系着乳粉的成品质量。利用单片机根据排风温度调节变频器的频率控制进奶量,从而来控制乳粉的干燥过程,其控制要比常规的人工控制方便、准确,而且对于提高乳粉的干燥质量、提高劳动生产率具有实际意义。

Along with the calculator technique of continuously universal, control the production line to already and more and more cause the every trade thoughtful of with calculator. Single slice industry control for machine conduct and actions the most typical into type system, already quilt extensively apply toing the every kind of type inside. Development trend for purpose for automatic control for calculator controling technique applying in production on--linely, realizing production line, at the same time passing productioning industry the spot circumstance proceeding supervise and control, attaining enhancing the management, increasing product quantity, increasing the production efficiency, lowering laboring the strength, is current business enterprise producing controling the management of single slice. In the milk powder production line inside milk powder the dry is an important work preface, it to directly relate toing, in the milk powder that produce the finished product quantity of the milk powder. Make use of the dry quantity for artificial control for dry process for machine according to row breeze temperature control entering milk measuring, from since then controling the milk powder, its control wanting comparing the normal regulations convenien.ee, accurately, and for exaltation milk powder of single slice, increase to labor the rate of production to have the actual meaning.
