本文介绍了一种可以现场修改协议和增加新协议的三层协议定制机制模型的设计与实现,详细阐明三层协议定制机制模型的各种相关原理和关键技术,介绍了两种编程实现结构,适合汇编和C语言的多表分析结构和适合C++、C#和Java等高级语言的单表映射结构。同时,详细介绍了在实际工程上使用单表映射结构在嵌入式系统Windows Ce上开发三层协议定制机制模型的过程,在一定程度上解决了解决水利信息化系统中多源设备的整合以及不同代产品的混合使用的问题。
This paper introduces the design and implementation of a three-layer protocol custom mechanism model that can modify protocols and add new protocols in the field, and elaborates various related principles and key technologies of the three-layer protocol custom mechanism model in detail, and introduces two programming implementation structures, Multi-table analysis structure suitable for assembly and C language and single-table mapping structure suitable for high-level languages such as C ++, C # and Java. In the meantime, the process of developing a three-layer protocol custom mechanism model on the embedded system Windows Ce using a single table mapping structure in detail is introduced in detail, which solves the problem that the integration of multi-source devices in water informatization systems and the differences Generational mixed use of the problem.
