COURIER-300 Spectrometer Data Processing System

This coefficient is the standardized coefficient of copper Road. Where 7 is the filter coefficient. General value for the 0.7: R-based scale factor times; R. . . . For the previous scale factor. Measurements obtained by the slurry flow in the copper measurement channel through the dead time corrected pulse count (for the flow channel, in the range of 1 to 14, which Ⅳ calculation methods and standard samples of copper measurements Road, after a dead time corrected the same number of pulses) is multiplied by this factor, by standardized pulse intensity of copper Road, be elected to the grade of the corresponding model, get all the copper content of the slurry flow. The standardization of pulse strength: = RT convex, the other channels (such as iron, zinc, molybdenum and scattering channel) is calculated with this same standard. After the pulse intensity are standardized, its model into the corresponding grade, but also worried by the flow of slurry and slurry concentration of various elements in and print their reports and historical documents into the system or transfer to the host through the communication interface machine process management and process control. In this process, but also tested on the scale factor. Once the scale factor exceeds the rate of change limit,[link widoczny dla zalogowanych], the main program will give an alarm or stop measurement, display and print-related information, notify the operator to take appropriate measures to ensure that equipment is always in normal working condition. The standard scale factor calculated 实际上 the change is for less than 3% of the cases in which the small drift of the measures taken, which are essentially within one point method correction. If the scale factor relative to the target strength of the deviation of greater than 3% and less than 10%, with a ratio of more than a simple correction method is impossible to obtain satisfactory results. Such as the replacement of x-ray tube. Detector, UV lens group 66 pieces of Mining and Metallurgy pulse amplifier and other major components or change the measurement conditions (change in x-ray tube high voltage or operating current, high voltage detector to change the value of the baseline spectral channel and channel width), may have a greater drift. In this case, you need to use a linear regression analysis to compensate, this method is also known as F Correction. F correction is installed in the instrument, a set of standard samples were measured, respectively, the pulse strength of their record, when that apparatus have a big shift, and then samples were measured for this standard, these two sets of data, simple linear Tonggui, each measuring channel can be obtained correction factor F, which was expressed as:,:. Ⅳ i + where: i is 1 to 5, corresponding to Cu, FeZn, Mo and Sc; the flow channel, in the range of 1 to 14. Solutions obtained using the regression method. And then measured by the end of the first cycle of a pulp flow l all measured elements were standardized generation pulse counting intensity can be obtained after the correction equation F corrected pulse intensity, and then calculated for each element in turn content . 3 Conclusion This system was formally delivered in September 1997 with Phoenix Mountain Copper Mine. Because the program runs in the WINDOWS environment, and the integration of a 30-COURIER some new techniques and new data processing strategy, so the system design of advanced,[link widoczny dla zalogowanych], simple operation, intuitive man-machine interface is good. The overall performance of the whole system is far superior to the old COURIER-300 system by the on-site leadership, technical personnel and operators alike.
