HY136型六通道X、γ辐射场报警装置的研制

Design of HY136 Six-channel Radiation Level Annunciator

利用微处理器并行总线上的两个NEC8253计数器对六通道核辐射探测器输出的脉冲同时进行计数,微处理器计算、显示每一个通道的辐射剂量水平。有任何一通道的辐射剂量水平大于设定的剂量水平时,蓝灯灭、红灯亮,并发出音响报警,提示工作人员不要进入辐射限制工作区。

Counting of the output impulses of the six-channel nuclear radiation detector with the two NEC8253 counters on the parallel bus of the micro processor, which will count and display the radiation level of each channel When any one channel＇s radiation level higher than the setup level, the blue light will be off and the red light will be on, and make alarm, in order to warn operators off the radiation working area.
