摘要: 为提高矿用X射线核子秤的计量稳定性，从防爆型X射线源和计量零点2个方面给出了具体方法：利用X射线探测器监测X射线源输出的X射线能量和强度，通过在X射线源内加装监控网络模块接收X射线探测器监测的X射线参数，并与设定的X射线参数进行比较，从而反馈控制防爆型X射线源的管电压和管电流，保持X射线源输出的X射线参数稳定；用防爆型X射线源的管电压、管电流的平均值来定义源强零点，通过X射线探测器实时采集X射线参数并与计量零点、源强零点进行比较，从而反馈调整计量零点和源强零点，克服输送机工况变化及X射线管老化对矿用X射线核子秤计量零点的影响。测试结果表明，该方法能有效提高X射线的稳定性，保证矿用X射线核子秤的计量稳定性。Abstract: In order to improve measurement stability of mine-used X-ray nuclear scale, specific methods were given from two aspects of explosion-proof X-ray source and measurement zero point. Energy and intensity of X-ray which are output from X-ray source are monitored by X-ray detector, and the monitored X-ray parameters are received by monitoring network module which is installed in X-ray source. By comparing the monitored X-ray parameters with the set X-ray parameters, tube voltage and tube current of the explosion-proof X-ray source are controlled to keep stable of X-ray parameters. Source intensity zero point is defined by average value of the tube voltage and the tube current of the explosion-proof X-ray source. X-ray parameters are collected in real time through the X-ray detector and compared with measurement zero point and the source intensity zero point, so as to adjust the measurement zero point and the source intensity zero point to overcome influence of conveyor condition change and X-ray tube aging on the measurement zero point. The test result shows that the methods can effectively improve X-ray stability and ensure measurement stability of mine-used X-ray nuclear scale.
