【摘要】 在对嵌入式电网分析仪系统功能分析的基础上,采用模块化的设计思想,设计并实现了电网分析仪的扩展模块,突破了各种现有电能表在硬件构成上所有功能合为一体的构建模式,增加了通讯、电能计量/日历、继电器控制、模拟量输出等扩展功能。由于其模块化的结构特点,使得功能模块可现场更换、通信和分析处理控制功能的变更与扩展都十分灵活。这种模块化的设计方法扩展了主机功能,便于用户根据不同的场合选择使用,可以满足将来多变的需求。更多还原

【Abstract】 Based on the analysis of the functions in supply network analyzer,the idea of modularization was applied to design and im-plement the extended modules of supply network analyzer,which broke the design mode of all kinds of existing electrical meters which all functions are as a whole in the structures,added functions of power energy calculation/calendar and relayed control and analogue output etc.Due to its modular structure,it made the modules be field-upgradeable,and so it can flexible meet the requirements of the change and expansion of communication and analyzing,processing,controlling functions.This modular approach facilitates the functional extension of the host machine,and it is convenient for the users to choose according to different conditions,and it will meet the varying needs in the future.更多还原
