核电站DCS系统与第三方系统通信时间测量方法

Nuclear Power Plant DCS System and the Third-Party System Communication Time Measurement Method

核电站DCS系统作为集中控制平台,面临着和多个第三方系统通信,但双方并非进行了高精度的时间同步,现场信号到达DCS的传输时间不得而知。本文巧妙的设计一种方式,通过注入和输出的波形比较,测算出两者之间数据的传输时间,为通信方式的选择及通信参数优化设置提供了依据。

Nuclear power plant DCS system as the centralized control platform is faced to multiple third-party systems for communication. But both sides do not take high-precision time synchronization so that the transmission time of field signal to DCS is unknown. This paper has ingeniously designed a method by comparing the injection and export waveforms to measure the data transmission time between both and provide basis for the selection of communication method and communication parameter setting.
