基于UCLinux的分布地热空调控制器的设计及其任务调度的研究

The Design of Distributed GSHP Controller and Tasks Schedule Based on UCLinux

现在绿色环保的地热空调(GSHP)应用范围越来越广,但是通常是使用PLC作为控制器的小型系统,不利于大规模应用和控制算法的实现。文章提出了一种分布式地热中央空制系统的硬软件的实现。它的硬件体系是分布式的结构,核心是“本地简单远程复杂”,它采用FUZZY+PID的控制方法。软件采用uclinux操作系统,采用基于Qos的二级层次反馈调度算法作为任务调度。实际运行结果表明,该系统在实际运行中节能效果显著。由于可以通过互联网进行监视系统的运行状态,因此维护也非常简单。

This paper presents a novel distributed terrestrial heat air-condition controller architecture for large scale applications.The keystone of this architecture is 'simple local and complex remote'.The control method is FUZZY+PID. This paper proposes an open two-level hierarchical schedule basic model and its realizing algorithm based on quality of service(Qos).This system can be monitored by Internet,which gives afford for maintenance.
