摘　　要：针对传感器接口类型众多、实时性差、不满足电网系统的标准化要求,且传感器通信链路异常易造成装置误告警,而采用光纤组网通信会造成现场交换机的投入过多,造成成本增大的问题,提出了一种基于HSR光纤环网的即插即用传感器设计方法。采用HSR光纤环网实现传感器和监测装置的实时通讯,减少了交换机的投入,提高了通信的可靠性;同时,传感器采用电子数据表单实现参数信息的自描述,在监测装置侧通过网络协议解析模块NCAP实现传感器TEDS表单及传感器信息的自识别和配置,实现传感器即插即用,降低现场安装和运维成本。In view of the sensor has many types of interfaces with poor real-time performance,which cannot meet the requirements of the standardization of power grid system,and the abnormal sensor communication link will cause the false alarm of device,while the optical fiber network communication can cause the cost increase problem of switch,this paper proposes a plug and play sensor based on HSR optical fiber ring network design method.The real-time communication of sensor and monitoring device is realized by using HSR fiber loop network,and the input of switch is reduced,and the communication reliability is improved.At the same time,the description of sensor parameter information is realized by using electronic data form,and the recognition and configuration of sensor information is realized through network protocol parsing module NCAP sensor TEDS form on the monitoring device side,as well as the plug and play of sensor,which reduces the site installation and operational cost,and improves the reliability of the system.
