This paper introduces the development process of the software from the aspects of interface design, algorithm analysis, parameter meaning and so on. Magnet track smoothing means that under the conditions of meeting absolute accuracy, if the relative position error of the adjacent magnet is too large, it will cause the loss of beam, we call the track curve is not smooth enough. Smooth analysis can find these magnet components, the curve is smooth after a reasonable ad-justment. The software is based on the least square method. The software is tested by using the data of HLS storage ring, the results meet the needs of the work.
