海洋放射性原位监测相比于传统采样回实验室分析可以实现连续、实时、自动化监测。研究了基于大浮标的海洋放射性原位监测系统,使用放射性测量传感器测量周围环境的放射性数据,使用GPS确定所测环境坐标,通过北斗通讯的方式将所测得放射性数据、位置信息等发送给岸站,岸站收到数据后计算并显示放射性测量传感器所测周围环境放射性数据能谱;研究设计了一种分包发送数据,数据丢包补发机制,解决海洋放射性数据量大,传输时间长,数据不全会造成解谱不准确的问题。最后通过实验室长期实验验证,长期数据平均接收率达到98%以上,能够利用海洋放射性原位监测系统实现准确可靠的监测。 |

The in-situ marine radioactivity monitoring can be continuous, real-time and automated, compared with traditional laboratory analysis. The in-situ monitoring system of marine radioactivity based on a buoy was studied. The radioactivity measuring sensor is used to measure the radioactivity of the surrounding environment. The position of the measured environment is determined by GPS. The measured radioactivity data and position are transmitted to the shore station by beidou. After the shore station receives the data, it calculates and displays the radioactivity energy spectrum of the surrounding environment measured by the radioactive measuring sensor. A multi-packet transmission and lost data re-sending mechanism is studied to solve the problem that the amount of ocean radioactive data are large, the transmission time is long, and if the data are incomplete, it will cause parsing spectrum errors. Finally, the average receiving rate of long-term data is over 98%, and it is possible to use the in-situ marine radioactivity monitoring system to achieve accurate and reliable radioactivity monitoring by long-term laboratory tests. |
