Example (b):
the structure of the information acquisition time correction system of the intelligent terminal device in the embodiment is shown in fig. 1, and includes an information acquisition module 101 and an information reporting module 102 which are arranged in the intelligent terminal device; an information receiving module 103 and an information processing module 104 which are arranged in the information acquisition server;
the information acquisition module 101: when a preset event occurs, the information acquisition module is triggered to perform relevant information acquisition actions and organize the information into a message in an appointed format and send the message to the 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 simultaneously acquired and added to the message information to be reported; as a specific example, the format of the intelligent terminal device information collection message is shown in fig. 2. Wherein, the Time information 201 refers to Time information based on a system clock; tick information 202 refers to time information based on the system beat; the device information 203 refers to device-related information that needs to be collected.
The terminal information reporting module 102: the server is responsible for packaging and processing the message sent by the information acquisition module and then sending the message to a specified server; in the embodiment, when the intelligent terminal equipment reports information, the system clock information and the system beat information of the intelligent terminal equipment at the reporting moment are acquired simultaneously; replacing the system beat information at the collection time in the message information by using the difference between the system beat information at the reporting time and the system beat information at the collection time; checking the system clock information of the acquisition time by using the system clock information of the report time, and replacing the system clock information of the acquisition time in the message information by using the system clock information of the report time if the system clock information of the acquisition time is not synchronous; then, the message information is packaged and reported to a server;
the system clock information of the acquisition time can be verified by using the system clock information of the reporting time through comparison with a preset time threshold, the time threshold is numerical value information representing a certain time length, and whether the system clock of the reporting time and the system clock of the acquisition time are in the same time domain can be judged through comparison between the difference between the system clock of the reporting time and the system clock of the acquisition time and the time threshold. If the difference is smaller than the time threshold, the system clock information of the acquisition time is synchronous, otherwise, the system clock of the acquisition time is not synchronous.
The server information receiving module 103: the server is responsible for unpacking and preprocessing message information reported by a receiving terminal and then sending the message information to a server information processing module; in this embodiment, when the server information receiving module 103 receives the message information, system clock information at the server receiving time is obtained; checking the system clock information in the message information by using the system clock information at the moment received by the server, and replacing the clock information in the message information by subtracting the network transmission delay time from the system clock information at the moment received by the server if the system clock information in the message information is not synchronous;

If the difference is smaller than the time threshold, the system clock information in the message is judged to be in the same time domain, and if not, the system clock information in the message is judged to be not synchronous.
In addition, the network transmission delay time refers to the time length between the time when the intelligent terminal device reports the message and the time when the server receives the message, which is relative to the same reference clock. The average value can be obtained by performing single calculation or multiple calculations on the information acquisition and reporting carried system clock information after the system clock is synchronized and the system clock information when the server receives the message information.
The server information processing module 104: and is responsible for processing message information. In this embodiment, 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 before analyzing and processing the device state information in the message information. Specifically, if the system clock at the time of information acquisition is synchronous, the clock information in the message information is the message timestamp information; if the system clock at the information acquisition time is not synchronous, the message timestamp information = clock information in the message information-system beat information in the message information.
Based on the above system, when implementing the information acquisition time correction, the embodiment first sets a time threshold Tt in advance, which is used to determine whether two system clocks are in the same time domain. And presetting a network transmission delay time Td for reckoning the system clock information of the time reported by the intelligent terminal equipment by receiving the system clock information of the time from the server. The Td can be obtained by performing single calculation or multiple calculations and averaging according to the information acquisition and reporting carried system clock information after the system clock synchronization of the intelligent terminal device and the system clock information when the server receives the message information.
The information acquisition time correction flow is shown in fig. 3:
when the terminal information acquisition module 101 acquires information, the terminal information acquisition module 101 acquires current device system clock information Time1 and duration information Tick1 corresponding to the current device main CPU beat number, and adds Time1 to the Time information 201, tick1 to Tick information 202, to form message information 301; the message information 301 includes the device information, time1 information, and Tick1 information.
When the terminal information reporting module 102 reports information, the terminal information reporting module 102 acquires system clock information Time2 of the current device and Time length information Tick2 corresponding to the beat number of the main CPU of the current device; if the Time2-Time1> Tt, replacing the Time information 201 in the message with the Time2; replacing the Tick information 202 in the message with Tick2-Tick1; forming message information 302; if the Time2-Time1 is not more than 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 specified server.
When the server information receiving module 103 receives information, the server information receiving module 103 obtains current server system clock information Time3; if the difference between the Time3 and the Time information in the message is greater than Tt, replacing the Time information in the message information by the Time 3-Td; forming message information 305; if the difference between Time3 and the Time information in the message is smaller than or equal to Tt, the information in the message is kept unchanged, so that a message 304 (Time information is Time 2) or a message 306 (Time information is Time 1) is formed.
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 309 in fig. 3; if Time1 is not synchronized and Time2 is synchronization information, 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 in 308 of fig. 3.
Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments and are not intended to limit the present invention. It should be noted that those skilled in the art can make various changes, substitutions and alterations herein without departing from the spirit of the invention and the scope of the appended claims.
