關鍵詞:區域伽馬中子探測系統 網址:www.bjbsf.cn 日期:2016/5/18 17:51:28

RAM-1000區域輻射監測系統(包括區域GM伽瑪與中子監測裝置)可以對特定場所內的輻射場進行監測,給出各探測裝置所在位置的劑量率數據,實現輻射監測信息的現場顯示與報警,同時與輻射監測系統主機相連,將輻射監測信息上傳,實現輻射監測信息的集中管理。
該輻射監測系統可以分為探測裝置部分、就地處理箱部分和輻射監測系統主機。探測裝置部分根據測量任務的不同分為區域γ測量裝置、區域中子測量裝置和事故后測量裝置;就地處理箱與探測裝置之間通過兩兩雙絞的4芯屏蔽電纜相連,就地處理箱給探測裝置供電并處理來自探測裝置的測量信號,實現輻射監測信息的現場顯示、報警和存儲,就地處理箱與各探測裝置之間采用CAN總線協議通訊;輻射監測系統主機與就地處理箱之間通過雙絞的2芯屏蔽電纜相連,可對就地處理箱上傳的輻射監測信息進行集中管理和控制,輻射監測系統主機采用DeviceNet總線協議與就地處理箱通訊。
