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。
With the development of the power industry, more and more types of power equipment begin to be applied to the production. How to quickly and conveniently connect the newly added equipment to the application system and well match the new equipment specification becomes a research hotspot. One of the ways that the new protocol is currently handled is to develop a new code that matches the new one, but it is a repetitive and heavy workload. The second is the use of protocol converter to achieve the new protocol and the original protocol conversion, but the method of system application layer code larger modifications, while reducing system compatibility, stability, interoperability and software upgrade smoothly ability. This paper presents a middleware-based access method of power equipment, through the middleware layer to shield different protocols between different devices, message differences, to the application layer to provide a unified interface to reduce the workload of the new protocol, and finally by the total call Command examples to illustrate the middleware layer of the application layer and device specifications match.
