【摘要】 该监测器能够快速连续地监测空气中人工β放射性气溶胶的体积活度,如果超阈会自动报警。仪器的取样和测量是同时进行的,因此该仪器具有响应时间短的特点。仪器的控制采用了Motorola的高性能32位微处理器和uCOS-Ⅱ嵌入式操作系统,并提供了多种通讯接口,方便了仪器的控制及测量数据的获取。更多还原

【Abstract】 This monitor can continuously and quickly measure the volume activity ofβradioactive aerosol in air. If the result is over a certain threshold, it can alarm automatically. This monitor has a short response time because it samples and measures the radioactive aerosol simultaneously. The control of this monitor is based on 32-bit microprocessor of Motorola Company and uCOS - Ⅱ embedded operation system. In addition, this monitor provides several communication interfaces to make it easy to control the monitor and acquire the measurement data.更多还原
