摘　　要：为提高中子法在线煤质分析仪的测量精度,对其电学系统进行改进。在原设计的基础上重组了部分冗余部件,采用DSP+USB方案优化了多道谱仪,选用11点平滑公式进行数据处理。实验表明,改进后的系统测量精度比原系统显著提高,测量数据与化学检测结果吻合,验证了系统改进措施的可行性。Aimed at a greater accuracy of online coal analyzer based on the neutron measurement, this paper is devoted to improving electrical system. The improvement consists of reconstructing some re- dundant components in original design, optimizing multi-channel spectrometer using DSP ＋ USB scheme, and applying 11-point smoothing formula of data processing. Experiments show that the improved system has a much greater measurement accuracy than the original system. Measurement data, consistent with the chemical test results, verifies the feasibility of the improved system.
