AT2327辐射监测器(车辆辐射检测器)

2327transportnyy-2

基于AT2327辐射检测仪制成的通道式辐射监测系统,用于检测通过检查点车辆的辐射剂量。

描述

操作原理

车辆辐射监测系统是基于BDKG-11/1BDKG-19智能辐射检测探头制成的。

开启系统后,辐射监测器自动转换为本底辐射测量模式。测量完成后系统计算辐射阈值,此时仪器闪烁黄灯提示。计算完辐射阈值后闪烁绿灯,提示仪器准备工作。

当车辆通过检测器时,安装在检测器头部的红外传感器能够检测车辆位置,并将辐射检测仪从本底测量模式切换到辐射检测模式。

在检测模式中,传感器通过RS485接口将数据传送到计算机。当辐射剂量率超过阈值时,系统会通知工作人员检查放射源。系统会在屏幕上显示探头编号和探测时间。

当辐射剂量超过阈值或系统内部件失灵时,会闪烁红灯,并在屏幕上显示危险区域。排除故障或找到问题后,传感器自动重置并重新计算阈值。

控制面板用于设置阈值计算参数、查看智能探头状态、校准实时时钟、设置密码、查看测量数据等工作。

如果需要,智能探头可以加装中子探测器。
