智能电网中电力设备接入中间件的设计

摘要

With the development of the power industry, and more types of electrical equipment being used in production, how to quickly and easily add new devices to the application system and match the new equipment protocols has become a hot topic. One kind of current methods for new protocols is developing new code to match these protocols, which has too heavy workload. The second method is to use protocol converters between new protocols and the original protocols, which needs great changes of application code and at the same time reduces system’s compatibility, stability, interoperability and the ability of software upgrade smoothly. This paper presents a power devices access method based on middleware to mask the differences on different packets between different devices and different protocols, and provide a unified interface for application layer to reduce the workload of adding new protocol. In the final section, one example of total by-call command is illustrated to explain how to match the application layer and device statute by design the protocol packet of the middleware layer.%随着电力行业的发展，越来越多种类的电力设备开始应用到生产中来，如何方便快捷地把新增设备接入到应用系统的同时很好地匹配新增设备规约成为研究热点。目前对新增规约处理的方法中的一种是开发新代码匹配新增规约，但是这种方式重复工作量大。第二种是使用规约转换器，实现新增规约与原来规约的转换，但是该方法对系统应用层代码修改较大，同时降低了系统的兼容性、稳定性、互操作性和软件平滑升级的能力。本文提出一种基于中间件层的电力设备接入方法，通过中间件层来屏蔽不同设备不同规约间的报文差异，向应用层提供统一接口，降低新增规约的工作量，最后通过总召命令实例来说明中间件层对应用层与设备规约的匹配。
