RTOS技术在变电站通信服务装置中的应用

Application of the RTOS Technique in the Substation Communication Server Device

随着国家对变电站综合自动化的要求不断提高,变电站内的通信服务装置显得越来越重要;由于它用于各电压等级变电站的综合自动化系统与远方调度等的通信连接,在整个综合自动化中起不可缺少的纽带作用。结合实际情况,提出了基于实时多任务操作系统(RTOS)的变电站通信服务装置的设计和研究,并且引入了实时多任务操作系统的内核NucleusPLUS来完成主体软件的设计,有重点地设计了通信服务装置中管理主模块及部分接口模块。通信服务装置采用了合理的模块化设计,从而保证了整个综合自动化系统的兼容性、通信实时性和可靠性。

With the constant improvement of the request for substation comprehensive automation, the communication service device in the substation is more and more important. Because it is used in the communications between the comprehensive automation of varied voltage grade substations and the dispath in distance, it works as a tie in the comprehensive automation. The dissertation has combined the actual conditions and put forward the design of the communication service device of substation based on real time operation system （RTOS）. The dissertation has introduced Nucleus Plus, which is the kernel of the RTOS, and complicated the designs of the primary management module and some interface modules. As adopting optimized module designs in the communication service device, the compatibility, communication real-time quality and dependability of the whole comprehensive automation system are assured.
