摘要
为了实现继电保护专业管理现代化,提出了录波数据、保护信息远传的方案。针对现场实际情况,开发设计了基于QNX实时操作系统的通讯管理机,在硬件结构上可以满足当前电力系统中多数智能终端单元的通讯需求;同时,软件的体系结构采用模块化和层次化的设计思想。实时操作系统的应用,改变了传统软件的开发过程,能克服顺序结构软件的缺点,并且具有模块化高,裁剪自如、易于扩展等特点。该通讯机的使用,较好地解决了不同保护、录波装置的联网问题,从整体上大大提升了电网调度运行管理水平。
In order to realize the modern administration of relay protection, this paper presents a plan for realizing remote transmission of recorded data and protective information. To the actual situation, a communication manager based on QNX RTOS (Real Time Operation System) is developed. Its hardware structure can satisfy the communication requirements of most intelligent terminal units, while the modular and layer structure of the system software is used in design. The application of RTOS has changed traditional development and can overcome the disadvantages of sequentially structural software. RTOS has some unique characteristics, such as high modularization, freely cut-out and easy extensibility.The present state of the operation and management of dispatching automation has been highly promoted because the use of communication manager can solve the networking scheme of microprocessor based different protections and fault recorders.
