微内核结构的测控系统软件

Control System Software Based on Micro-Kernel

测控系统软件是测控系统重要组成部分,直接影响着测控系统的运行。提出了一种基于微内核结构的测控系统软件设计方法,该方法以消息数据处理为中心,通过统一的消息接口将测控任务插件化,利用受控的消息传递机制实现测控软件各个功能模块间的交互,并在微内核单元管理下进行HPFS-HRRN的测控任务调度;基于虚拟仪器技术,设计和实现了水平分层结构替代纵向层次结构的测控系统软件。实验测试表明,将该方法应用到L-乳酸发酵过程测控系统软件设计中,所构建的测控系统具有较高的可靠性、通用性和可扩展性。

As an important component of the measurement and control system, control system software influences on the running of the measurement and control system directly. A new method to design the measurement and control system software based on Micro-Kernel architecture was proposed. On the basis of message processing, measurement and control task was turned into a type of plug by a unified message interface, the vertical hierarchy of in measurement and control system software development was replaced by hierarchical structure under measurement and control task of HPFS-HRRN controlled by Micro-Kernel unit. The measurement and control system software was designed by virtual instrument. The experiment results show that this system software has the ability of extension, good flexibility, and strong reliability.
