基于模块化组态设计的配电终端设计与开发,主要是在设计时将配电终端硬件按照不同的功能需求设计为独立的硬件模块,模块可以采用导轨安装等方式进行任意组合,模块安装不再受限于机箱尺寸及插槽数量,因此模块种类及数量可以按照工程需求任意配置,模块间通过带冲突检测的快速通道抢占机制进行通信且模块实现即插即用。文中主要从硬件模块分类及结构设计、高速总线接口及通信机制设计、模块自适应接入设计等方面对所提出的基于模块化组态设计的配电终端进行研究和阐述,主要包含了高速总线控制技术、基于冲突检测的高速总线资源抢占技术、基于自适应接入的模块即插即用技术等内容。
Design and development of power distribution terminal based on modular configuration design mainly design the power distribution terminal hardware as independent hardware modules according to different functional requirements during design, and the modules can be arbitrarily combined by means of rail mounting, and the module is installed And then limited by the size of the chassis and the number of slots, the type and number of the modules can be arbitrarily configured according to engineering requirements. The modules communicate through the fast channel preemption mechanism with collision detection and the modules are plugged and used. This paper mainly researches and expounds the power distribution terminal based on modular configuration design in the aspects of hardware module classification and structure design, high-speed bus interface and communication mechanism design, module adaptive access design and so on, mainly including high-speed bus Control technology, high-speed bus resource preemption based on collision detection, and plug-and-play technology based on adaptive access.
