s301, responding to the instruction of class attendance, generating a download message, and sending the download message to the signaling center server within a preset time period.
Typically, the download message includes class type information, such as: the third section of the fifth grade english lesson, the second unit of the sixth grade math lesson, etc. The terminal device responds to the instruction of class to generate a download message, and sends the download message to the signaling center server within a preset time period, for example: the terminal equipment receives a first lesson instruction, analyzes the first lesson instruction, determines that the No. 3 unit 1 speaking of a language lesson needs 1 hour after 30 minutes, generates corresponding downloading information according to the information, and sends the information to the signaling center server within 10 minutes.
S302, receiving a signaling file responding to the download message from the signaling center.
Generally, after sending the download message, the terminal device receives a signaling file from the signaling center in response to the download message, for example: the signaling file comprises signaling for class taking, designated video stream pulling, courseware loading, question answering starting, question answering ending, class leaving and the like, the terminal equipment can also detect the integrity of the signaling file, and if the signaling file is damaged, the signaling file can be downloaded again from a signaling center server, and the signaling file is not received within preset 10 minutes or the like, the downloading message can also be sent again.
S303, loading the signaling file into a memory unit for analysis to obtain time information, and carrying out sequencing check processing on the signaling file based on the time information.
Generally, after receiving a signaling file from the signaling center in response to the download message, the terminal device loads the signaling file into a memory unit to analyze the signaling file to obtain time information, and performs sequencing check processing on the signaling file based on the time information, for example: the terminal device loads the signaling file from the disk space to the memory unit, and then performs sequencing processing according to the sending time, for example: the lesson instruction is used as a No. 1 signaling to determine that the sending time is 4 points, the recitation instruction is used as a No. 2 signaling to determine that the sending time is 4 points and 10 minutes, the picture a is loaded as a No. 3 signaling to determine that the sending time is 4 points and 20 minutes, and the answering starting is used as a No. 4 signaling to determine that the sending time is 4 points and 30 minutes and the like.
S304, based on a preset segmentation threshold, carrying out segmentation processing on the signaling file after the sequencing check processing to obtain a plurality of segmentation files, determining corresponding segmentation file names, and storing the plurality of segmentation files in the disk space.
Generally, after the terminal device performs sequencing check processing on the signaling file, the terminal device performs segmentation processing on the signaling file after the sequencing check processing based on a preset segmentation threshold to obtain a plurality of segmented files, determines corresponding segmented file names, and stores the plurality of segmented files in the disk space, for example: after the terminal device performs sequencing check processing, it is determined that the training file has 45 signaling, a segmentation threshold value is set to 10, and segmentation bits of the 45 signaling, 1-10 segmentation files a, 11-20 segmentation files b, 21-30 segmentation files c, 31-40 segmentation files d, 41-45 segmentation files e, and the like can be stored in the previous disk space, and all the segmentation file names are written in a local cache, and the like.
S305, detecting courseware time information, generating a loading instruction based on the courseware time information, and analyzing the loading instruction to obtain a segmented file name.
Generally, after the terminal device stores the plurality of segmented files in the disk space, it detects the session time information, generates a loading instruction based on the session time information, and analyzes the loading instruction to obtain the names of the segmented files, for example: when the terminal device detects that the class time information is 10 minutes or 10 minutes after 14 hours, a loading instruction A of a signaling needing to be loaded immediately is generated, and the terminal device receives the loading instruction A to determine that the first segment of the segmented file a needs to be loaded.
S306, inquiring the corresponding segmented file in the disk space based on the segmented file name.
Generally, after acquiring a segment file name, a terminal device queries a corresponding segment file in the disk space based on the segment file name, for example: and the terminal equipment determines that the segmented file name is the segmented file a, and can quickly query in the disk space according to the file name to obtain the data information of the segmented file a.
S307, determining the loading data volume, initializing a queue structure in the memory unit based on the loading data volume, and writing the corresponding segmented file into the initialized queue structure to generate a signaling queue.

After the terminal device queries the corresponding segment file in the disk space, determining a loading data volume, initializing a queue structure in the memory unit based on the loading data volume, and writing the corresponding segment file into the initialized queue structure to generate a signaling queue, for example: the terminal equipment determines that the loaded data volume is 10M, that is, the size of the segmented file a is 10M, then 100 initialization queue structures with proper length corresponding to the size are opened up in the memory unit, all the signaling in the segmented file a are sequentially written into each element of the initialization queue according to the arrangement sequence, the first signaling is written into the first element of the queue, and the tail part of the queue can be an empty element.
S308, receiving a signaling reading instruction, and reading the corresponding signaling in the signaling queue based on the signaling reading instruction.
Generally, after writing the corresponding segment file into the initialized queue structure to generate a signaling queue, the terminal device receives a signaling reading instruction, and reads a corresponding signaling in the signaling queue based on the signaling reading instruction, for example: and the terminal equipment determines that the course needs to be answered after 30 minutes, generates a corresponding signaling reading file, and reads the corresponding signaling from the queue after receiving the signaling reading file.
S309, detecting the residual signaling length, and acquiring the loading state of all the segmented files when the residual signaling length is smaller than a loading threshold.
Generally, the segment threshold is greater than the loading threshold, where the loading threshold indicates that after the signaling is loaded into the memory, the signaling is stored in the queue, and during class, one signaling is taken from the queue in sequence, and if the signaling in the queue is found to be running out, a supplementary signaling is used at this time (i.e., a signaling file is loaded from a disk), and when there are more signaling in the queue, a threshold for triggering a loading action is triggered, for example: if each signaling file contains 10 pieces of signaling and the loading threshold of the signaling queue is 100, loading is triggered when 100 pieces of signaling queue remain, and the signaling in the queue is still sent in the loading process. If there are 2 remaining queues, the loading is successful, and if there are 10+2 signaling in the queue, 12 signaling, or less than the loading threshold, the loading needs to be continued. After reading the corresponding signaling in the signaling queue, the terminal device detects the remaining signaling length, and when the remaining signaling length is smaller than the loading threshold, obtains the loading states of all the segment files, for example: and the terminal equipment detects that the length of the remaining signaling is 15 and is less than the loading threshold value 16, and if the segmented file b is determined not to be loaded into the signaling queue, the segmented file b is loaded into the signaling queue.
S310, determining an index value of the segmented file in the unloaded state, and writing the corresponding segmented file in the unloaded state into the signaling queue based on the index value.
Generally, the load state includes a load complete state and an unloaded state. After acquiring the loading states of all the segment files, the terminal device determines the index values of the segment files in the unloaded state, and writes the corresponding segment files in the unloaded state into the signaling queue based on the index values, for example: the method comprises the steps that a terminal device obtains a Map of a storage structure loaded by a segmented file, determines that the segmented file is in a loading completion state, adds 1 to an index value of the next segmented file to be loaded, identifies the segmented file as WAIT _ LOAD and writes the segmented file into the Map if the segmented file is determined to be in an unloaded state according to the index value of the segmented file, and then asynchronously LOADs the segmented file into a queue.
