Examples:
the structure of the information acquisition time correction system of the intelligent terminal equipment in the embodiment is shown in fig. 1, and the system comprises an information acquisition module 101 and an information reporting module 102 which are arranged in the intelligent terminal equipment; an information receiving module 103 and an information processing module 104 provided in the information acquisition server;
information acquisition module 101: when a preset event occurs, triggering related information acquisition actions and organizing information into a message in a contracted format to be sent to an information reporting module; in this embodiment, when the intelligent terminal device performs information acquisition, system clock information and system beat information of the intelligent terminal device at the acquisition time are acquired at the same time, and are added to message information to be reported; as a specific example, the format of the information acquisition message of the intelligent terminal device is shown in fig. 2. Wherein Time information 201 refers to Time information based on a system clock; tick information 202 refers to time information based on system beats; the device information 203 refers to device-related information that needs to be collected.
Terminal information reporting module 102: the message sent by the information acquisition module is packaged and then sent to a designated server; in the embodiment, when the intelligent terminal equipment performs information reporting, system clock information and system beat information of the intelligent terminal equipment at the reporting time are acquired at the same time; replacing the system beat information at the acquisition time in the message information by utilizing the difference between the system beat information at the reporting time and the system beat information at the acquisition time; and verifying the system clock information at the acquisition time by using the system clock information at the reporting time, and if the system clock information at the acquisition time is not synchronous, replacing the system clock information at the acquisition time in the message information by using the system clock information at the reporting time; then packaging and reporting the message information to a server;
the system clock information of the collection time can be checked by comparing the system clock information of the reporting time with a preset time threshold, the time threshold is numerical information representing a certain time length, and whether the system clock of the reporting time and the system clock of the collection time are in the same time domain can be judged by comparing the difference between the system clock of the reporting time and the system clock of the collection time with the time threshold. If the difference between the two is smaller than the time threshold, judging that the two are in the same time domain, indicating that the system clock information at the acquisition time is synchronous, otherwise, indicating that the system clock at the acquisition time is not synchronous.
Server information receiving module 103: the message information which is responsible for receiving the report of the terminal is unpacked, preprocessed and then sent to the server information processing module; in this embodiment, when the server information receiving module 103 receives the message information, the system clock information at the time of receiving the server is obtained; checking the system clock information in the message information by using the system clock information at the moment of receiving the server, and if the system clock information in the message information is not synchronous, subtracting the network transmission delay time from the system clock information at the moment of receiving the server to replace the clock information in the message information;

If the difference between the two is smaller than the time threshold, the judgment is in the same time domain, the synchronization of the system clock information in the message is indicated, otherwise, the synchronization of the system clock in the message is indicated.
In addition, the network transmission delay time refers to the time length that passes between the time when the intelligent terminal device reports and the time when the server receives the message relative to the same reference clock. The method can be obtained by carrying out single calculation or multiple calculation and averaging on the information acquisition and the reporting carried system clock information after the system clock synchronization and the system clock information when the server receives the message information.
Server information processing module 104: is responsible for processing message information. In this embodiment, before analyzing and processing the device status information in the message information, the server information processing module 104 calculates the message timestamp information by using the clock information and the system beat information in the message information. Specifically, if the system clocks at the information acquisition time are synchronous, the clock information in the message information is the message time stamp information; if the system clocks at the information acquisition time are not synchronized, the message time stamp information=clock information in the message information-system beat information in the message information.

When the terminal information reporting module 102 performs information reporting, the terminal information reporting module 102 acquires the current equipment system clock information Time2 and the Time length information Tick2 corresponding to the current equipment main CPU beat number; if Time2-Time1> Tt, then replace Time information 201 in the message with Time2; replacing the Tick information 202 in the message with Tick2-Tick1; forming message information 302; if Time2-Time1 is less than or equal to Tt, keeping the Time information 201 in the message unchanged, and only replacing the Tick information 202 in the message with Tick2-Tick1 to form a message 303; and finally, packaging the message and sending the message to a designated server.
When the server information receiving module 103 receives information, the server information receiving module 103 acquires the current server system clock information Time3; if the difference between the Time3 and the Time information in the message is larger than Tt, replacing the Time information in the message information with the Time 3-Td; forming message information 305; if the difference between the Time3 and the Time information in the message is less than or equal to Tt, the information in the message is kept unchanged, so as to form a message 304 (the Time information is Time 2) or a message 306 (the Time information is Time 1).
Finally, the server information processing module 104 calculates the message timestamp information: if Time1 is the synchronization clock information, the message timestamp is Time1, as shown in 309 in fig. 3; if Time1 is not synchronized, time2 is synchronization information, and the message timestamp is Time2- (Tick 2-Tick 1), as shown in 307 in FIG. 3; if Time1 is not synchronized and Time2 is not synchronized, the message timestamp is Time3-Td- (Tick 2-Tick 1), as shown at 308 in FIG. 3.
Finally, it should be noted that the above examples are only preferred embodiments and are not intended to limit the invention. It should be noted that modifications, equivalents, improvements and others may be made by those skilled in the art without departing from the spirit of the invention and the scope of the claims, and are intended to be included within the scope of the invention.
