数字化核测量仪器的网络通讯功能设计

Development of Network Communication Function for Digitalized Neutron Flux Monitoring Instrument

网络通讯功能是数字化核测量仪器必不可少的,也是较传统模拟核测量仪器不同的一项基本功能。如何满足各个目标电站不同的网络通讯结构及协议要求是在设计研制数字化核测量仪器工作中必须解决的一个重要问题。介绍了数字化核测量仪器通讯接口的总体设计方案,阐述了通讯接口的设计思路、设计要求,并以RS-485总线通讯为例,说明了通讯接口的具体实现。

It is essential for a digitalized Neutron Flux Monitoring Instrument to communicate with other parts of Instrumentation and Control System in a network environment, and it is fairly different from the case of traditional analogue nuclear instrumentation. How to satisfy all the requirements of different network structure and communication protocol, which might be adopted in different target nuclear power plant, is a key issue in the design and development of a digitalized neutron flux monitoring instrument. This paper describes the overall communication scheme, mainly discusses the design idea and the requirements of the communication interfaces and the implementation of the RS-485 interface as an example of the digitalized neutron flux monitoring instrument, which is under development in the institute.
