In order to operate the device correctly, the relevant parameters of the device must be set first, and the user sets the parameters and then applies the parameters to the device.
The default parameters can be directly obtained by obtaining the default parameters, and data capture can be directly carried out after the default parameters are obtained.
Similarly, before data analysis begins, a screening threshold needs to be set, and screening thresholds for different types of ores need to be set.
The set default screening threshold can also be directly obtained.
② data capturing module
After parameter setting is completed, data capture can be performed to acquire related data.
Data analysis module
The captured data is obtained from the device in a line-by-line scan, concatenated in time sequence. When no ore exists, the data value is stabilized at a certain value due to the fact that light energy is transmitted, when the ore exists after X-ray is added, the X-ray cannot transmit metal, so that the value is reduced, the ore can be calculated through the change of the value according to the difference of the values obtained by different kinds of ores, each ore forms an area similar to a matrix in the data, the approximate size of the area is calculated through an algorithm, a point at the center is taken, the coordinate on the machine and the time when the ore passes through the machine are calculated according to the row and column positions, and the coordinate and the time of the ore are output.
Specifically, as shown in fig. 2, since the data is acquired by traveling through the apparatus in a row, the ore data will be matrix-like data blocks, the data of each block differs according to the kind of ore, the ore data is stored in a two-dimensional array in advance, and according to the set maximum screening threshold, when the number in the array is smaller than this value, 1 is input in a new array of the same coordinates, whereas when the number in the array is larger than the maximum threshold, 0 is input, so that a more simplified new array of 1 and 0 is obtained, which is the same as the previous coordinates. Then, the position of each matrix needs to be judged, the upper, lower, left and right numbers of each number are added up and input into another new array with the same coordinate, when the value is 4, the number can be considered to be in an ore matrix, the left and right sides are searched firstly, the width of the matrix is obtained and then the up and down sides are searched, the height of the matrix is obtained, all the numbers in the matrix are cleared to be 0 to avoid repeated inquiry, then the number of the position with the same coordinate in the first array is obtained, the type of the ore is obtained by comparing the number with a screening threshold value, the time when clicking starts is obtained through a GetLocalTime function, the data interval is obtained according to the number of the lines, the data interval is added to the time, the accurate time when the ore passes through the equipment is output, and therefore, the time when the ore passes through the equipment, the size of the ore and the type of the ore can be obtained, the position of the ore on the conveyor belt is output accurately.
