the play information acquisition module is configured with a play information acquisition strategy, and the play information acquisition strategy comprises: acquiring file information played by the LED display screen once at a first acquisition time every interval, wherein the file information comprises a playing file name and a playing file format; acquiring a transmission log of a computer every first acquisition time, wherein the transmission log comprises a transmission file name, a transmission file format and a transmission time;
it should be noted that, the LED display screen plays the content in a projection manner, so that the projected content needs to be obtained by connecting a computer with a network; when the computer sends the projection content, the projection content is stored in a sending log, and the sending log is used for recording all the sent file names and file formats; the LED display screen projects after receiving the projection content; in the transmission process of the projection content, the content may be sent and changed due to some factors, for example, a video file with a format of mp4 is changed into an mp3 format due to network abnormality in the transmission process, and the playing content may be changed into a video file with other file names due to external attack, so that a sending log, the file names played by an LED display screen and the file formats need to be obtained for subsequent analysis and judgment;
the detection and analysis module is configured with a detection and analysis strategy, and the detection and analysis strategy comprises: acquiring a final transmission file name and a final transmission file format of the transmission time sequence, and marking the final transmission file name and the final transmission file format as a file name and a file format of the file to be played; setting a play similar value with an initial value of 0, comparing the play file name with the file name to be played, and adding one to the play similar value when the play file name is the same as the file name to be played; when the playing file name is different from the file name to be played, the processing is not performed; the playing file format and the file format to be played are processed in the same way; outputting normal playing information when the playing similarity value is equal to the first similarity value; outputting a detection signal when the play similarity value is smaller than the first similarity value;
in the implementation, the first similarity value is set to 2, and the correct content can be played only when the file name and the file format are the same as each other by the LED display screen because the file name and the file format are possibly changed in the data transmission process, so that the first similarity value is set to 2; when the file names or the file formats are the same or different, the playing similarity values are smaller than 2, and the LED display screen cannot correctly play the content sent by the computer; at the moment, the LED display screen is judged to be faulty, and further detailed analysis is needed, so that a detection signal is sent to the LED display screen;

TABLE 1-1 analysis delay time Table
The data is only used as reference, the actual value is determined by the network connection mode, the rated data transmission rate and the transmission distance together, and when the rated data transmission rate is lower and the transmission distance is longer, the situation that the analysis delay time is less than 1 second exists;

it should be noted that, the specific operation of "reestablishing a communication connection" in the reconnection maintenance policy relates to a connection manner, for example, reestablishing a TCP/IP connection or reconnecting to a server; for serial communication, serial connection needs to be re-opened, so that correct serial number, baud rate and other communication parameters are ensured to be used; in some cases, it may be necessary to reinitialize the communication device, such as reconfiguring a network device or restarting a communication module; the problem of a received connection interruption due to an abnormal connection can be eliminated and maintained by reestablishing the communication connection; and analyzing file information played by the reconnected display screen, and if the problem still exists at the moment, judging that playing contents are not synchronous due to abnormal hardware connection, and outputting hardware connection fault information.
