As shown in Figure 1, the invention process provides a kind of indoor test data visualization method, and concrete steps are as described below:
Step 1, read test data file.Test data file can be one, also can be a plurality of.Test data file can be that drive test produces, and also can be that CQT produces.This test data can be the indoor test data, also can be outdoor drive test data, when handling by the inventive method, for outdoor drive test data, will discard latitude and longitude information.
Step 2, parsing test data file obtain the sampled point record.Each sampled point record comprises timestamp, various wireless parameter value, longitude and latitude (if the words that have).In the data GPS longitude and latitude can be arranged, also can not have the GPS longitude and latitude.In the technical scheme that the present invention relates to, only be the preface demonstration sampled point that tiles with time, do not pay close attention to the true spatial location of sampled point.
Step 3, open indoor test data display window.This window is supported translation, the convergent-divergent to graphic entity, and like this, when sampled point quantity is many and can not show full-timely in window, the test data outside can the translation window can be observed overall general picture and local detail by convergent-divergent.
Step 4, in chronological order sampling number according to being plotted in the window by the specified layout mode.To each test data file, therefore test data need not to sort according to the time order and function journal.To each sampled point, calculate its displaing coordinate position.Calculation mode depends on preassigned layout type, for example, press line mode, be that sampled point is from left to right placed sequentially, when the sampled point number of delegation reaches predefined line width, by the interval newline of appointment, place sampled point so line by line sequentially, all draw up to all sampled points and finish.Press the row mode, be that sampled point is placed from top to bottom sequentially, when the sampled point number of row reaches predefined col width, set up another row by the interval of appointment, like this one places sampled point with being listed as sequentially, all draws up to all sampled points to finish.In addition, in order to divide sampled point to belong to which test file at a plurality of test files while show-timezones, before showing these test file data, showing a file sequence number, is the data in this document to represent this sequence number sampled point afterwards.
As shown in Figures 2 and 3.A kind of indoor test data visualisation system provided by the invention, this test data visualization system 300 comprises testing apparatus 100, and visualization device 200,

Described display unit 40 is used for sampling number is shown according to drawing in chronological order.
To handle the example that is visualized as of a plurality of test data files, technology contents of the present invention is done further explanation below.
The first step: read test data file.Test data file can be that drive test produces, and also can be that the CQT test produces.The GPS latitude and longitude information can be comprised, also the GPS latitude and longitude information can be do not comprised.Usually the content that writes down in the test data file is original communication message, comprises timestamp, original data stream.
Second step: resolve test data file, obtain the data record of each sampled point.From original communication message, sample according to predetermined mode, obtain the sampling number certificate.Each sampled point record comprises timestamp, wireless parameter value, longitude and latitude (if the words that have).In addition, in original communication message, extraction incident, layer three message are so that check related with sampled point.Logout comprises timestamp, event content.Layer three Message Record comprise timestamp, message content.
The 3rd step: open indoor test data display window.Indoor test data display window is not with numerical map, and the window support is browsed so that observe translation, the convergent-divergent of graphic entity.In addition, window also supports to show the legend of current observation wireless parameter, and the pairing interval of different colours.
The 4th step: in chronological order sampled point is plotted in the window by line mode.At first determine the sampled point maximum number that line width, row distance, line-spacing, every row show, line-spacing and row are apart from all fixing.From left to right be plotted in sampled point in the window singly according to fixing row distance then, when this row sampled point number surpasses the sampled point maximum number of every row demonstration, with regard to newline, the from left to right equidistant sampled point of drawing is all drawn up to all sampled points and to be finished.In addition, each indoor data file is when showing, the sequence number of display file before showing first sampled point is so which file what know follow-up sampled point correspondence is.2,11,12 3 numerals are for example arranged before sampled point, and what expression was opened is to be numbered three test files of 2,11,12, and the sampling number in the test file is according to the show after them.Data in the test file are plotted in indoor data display window according to above-mentioned row-by-row system one by one, on corresponding time sequencing position, with incident symbol plotting corresponding event.
In the 4th step, the symbol that sampled point is drawn can be specified in advance, round dot for example, square.The color of symbol plotting is determined according to the wireless parameter and the corresponding visual color rendering intent of current observation.For example, to incoming level RX_POWER, according to residing interval, use respectively green, blue, yellow, red or the like, represent signal quality by good to poor.
In the 4th step, if exist incident corresponding with sampled point, for example call drop is drawn call drop incident symbol at corresponding sampling point position, and sampled point and incident can be checked interrelatedly like this.Corresponding mode is to be foundation with the timestamp, nearest sampled point when finding incident to take place.A sampled point has a plurality of incident correspondences.
In the 4th step, can be corresponding with layer three message sampled point.By sampled point, can correspond to corresponding layer three message position according to timestamp, thereby both check interrelatedly.
By said method, the indoor test data are tiled in the window show, can observe signal quality and incident intuitively.For example, open the indoor test data file, flooding all is green sampled point, has that to experience network signal quality intuitively good.In addition, also can obtain further information, for example, open the indoor test data file, when pressing the line mode demonstration, upper part all is green, occur redness below, it is good then can to experience interior signal quality of preceding half period of test, poor signal quality in time second half section.If mark has incident, can learn the time that incident takes place, frequency, or the like.The information that these are detailed is that the network index statistical can not get.
By said method, can also analyze wireless parameter and layer three message more easily.In display window, can see the place of poor signal quality intuitively, perhaps sampled point is clicked in the place that takes place of incident such as call drop, and right mouse button can be checked layer three message before and after various wireless parameter values, the sampled point.
Be noted that when the application of reality,, should use latitude and longitude information as far as possible at the test data that has the GPS longitude and latitude.In second step of the foregoing description, when identifying is when having the test data of GPS longitude and latitude, then adopt general GIS visual means in the present industry, when identifying when being the test data of no longitude and latitude, it is visual then to adopt technical scheme of the present invention to carry out.To fixed tests such as CQT, because the GPS longitude and latitude is fixed, sampling point position is overlapped, at this moment in order to obtain more detailed information, also can adopt this bright technical scheme to carry out visual.In a word, the change of these details does not depart from the spirit and scope of the present invention.
Above-mentioned explanation illustrates and has described a preferred embodiment of the present invention, but as previously mentioned, be to be understood that the present invention is not limited to the disclosed form of this paper, should not regard eliminating as to other embodiment, and can be used for various other combinations, modification and environment, and can in invention contemplated scope described herein, change by the technology or the knowledge of above-mentioned instruction or association area.And change that those skilled in the art carried out and variation do not break away from the spirit and scope of the present invention, then all should be in the protection range of claims of the present invention.
