A browsing method of railway signal analog curve

The invention discloses a browsing method of railway signal analog quantity curve, which comprises the following steps: dividing all the sampled data collected into a set time length; calculating theaverage value, mean square deviation, maximum and minimum value of the data after segmentation to form a record; storing all records as data files; comparing the records in the data file one by one according to the detection parameters set by the user to find out the abnormal records; saving the abnormal record in the form of a table file, so that the user can open the table file of the abnormal record to browse, when the user clicks an abnormal record, the data analysis module calls out the data curve file and displays the data curve of the corresponding time period of the abnormal record. The invention can reduce the workload of the user, reduce the abnormal omission of the curve caused by the human negligence, further improve the working efficiency, and provide strong support for the reduction of personnel and
