摘　　要：针对一种新型抽注水中子能谱探测系统中存在抽注水效率低和水层组合切换耗时较长的问题,设计了一种在不改变水泵转向情况下实现抽水和注水2个功能的单泵抽注水装置,相比于自然抽注水,提高抽水效率10.34倍、注水效率3.29倍,并结合遗传算法给出了水层组合切换的近似最优控制,遍历32种组合共需2728 s,最优水层组合切换序列的效率是随机切换序列的5.76倍。实验结果表明,单泵抽注水装置能够大幅度缩短非测量用时,有效提高抽注水多球中子能谱探测系统的工作效率,相比于双泵设计节约了硬件成本和控制成本。In view of the problem that there is a low efficiency of pumping water and a long time-consuming switching of combinations of water cavities in a novel water-pumping-injection multilayered concentric sphere neutron spectrometer,we designed a system without changing the steering of the pump which can pump and inject water with a single pump,and the pumping and the injection efficiency of single-pump system were 10.34 and 3.29 times more than that of the natural way.Genetic algorithm was adopted to give the approximate optimal control of switching between the adjacent combinations,which only requires 2728 s to traverse 32 combinations,and the efficiency of the optimal switching sequence was 5.93 times more than the stochastic switching sequence.The experimental results show that the single-pump system can greatly shorten the non-measurement time,effectively improve the working efficiency of pumping and injecting water,and save hardware cost and control cost compared with the designs with double-pump.
