In a first aspect, an embodiment of the present application provides a terminal timing method.
Referring to fig. 1, the terminal timing method of the present application specifically includes the steps of:
s110, sending a first timing request to a first service end;
s120, receiving a first standard time generated by a first server according to a first timing request, and acquiring a first receiving time;
S130, obtaining a first timing time according to the first request time, the first standard time and the first receiving time;
and S140, updating the local time according to the first timing time.
In step S110, the terminal sends a first timing request to a first service end, where the terminal may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and in this embodiment of the present application, the terminal may also be referred to as a client terminal, for the production of an electric meter, where the client terminal mainly writes local time into the electric meter, as a start time of the electric meter, the service end is used to provide a standard time source, and performs time synchronization on the multiple terminals, and it needs to be described that the embodiment of the present application includes multiple service ends, where the first service end is one or more servers that are used to provide standard time in the multiple service ends. In practical application, the application environment of the application is as follows: the system comprises a computer cluster in a closed network environment, wherein the computer cluster basically comprises a plurality of or dozens of servers and a plurality of client terminals, the servers can be but are not limited to various MES servers, ERP servers and SAP servers, a first timing request refers to a request of the terminal for acquiring the time of the first server to a first server, the first timing request is used for timing the local time of the terminal, the first timing request comprises a first request time, and the first request time is the time of the terminal for sending the first timing request to the first server.
In some embodiments, the ways for providing the standard time source by the service end in the embodiments of the present application mainly include: one way is that a server for providing a standard time source is connected with the internet, and the server can realize a time setting function by acquiring standard time corresponding to the internet, specifically: the time setting function of the server is realized by setting a corresponding time server on an operating system of the server, and the other way is that the server for providing the standard time source is not connected with the Internet, in this case, the standard time source can be obtained by adopting an NTP protocol, in addition, the time interval of the server for obtaining the standard time source can be set, for example, time setting is carried out every second, and the accuracy of time checking is improved.
In step S120, the terminal receives a first standard time generated by the first server according to the first timing request, and obtains a first receiving time, where the first standard time is: the first server receives a standard time corresponding to a first timing request sent by the terminal, for example, beijing time, and the first receiving time is a time when the terminal receives the first standard time, that is, a time when the terminal receives a response of the first server.
In step S130, the terminal obtains the first time correction time according to the first request time, the first standard time and the first receiving time, and because the terminal puts forward the first time correction request to the first service end and the first service end responds to the terminal according to the first time correction request in the process of the first standard time, a time error caused by communication can be generated, so that the first request time corresponding to the first time correction request is required to be recorded, the first receiving time of the terminal receiving the response of the first service end is recorded, the time error corresponding to the first standard time is adjusted through the first request time and the first receiving time, and the first time correction time of the terminal requiring time correction is obtained after adjustment.
In some embodiments, as shown in fig. 2, step S130 specifically includes the steps of:
s131, obtaining a first time difference according to the first request time and the first receiving time;
s132, obtaining a first timing time according to the first time difference and the first standard time.
In step S131, the terminal obtains a first time difference according to the first request time and the first receiving time, specifically, subtracting the first request time from the first receiving time to obtain the first time difference, that is, a time difference between a time when the terminal sends the first timing request and a time when the terminal receives the first standard time.
In step S132, the terminal obtains the first time correction time according to the first time difference and the first standard time, and because the first server end consumes a certain time to send the first standard time to the terminal, for accuracy of time correction, the time consumed in the communication process needs to be considered, the first time difference, that is, the time consumed by the terminal to send the request and receive the response, before time correction is performed on the terminal, the time required by the terminal to perform time correction can be obtained by adding the first standard time to the time consumed by the first server end to send the first standard time to the terminal.
In step S140, the terminal updates the local time according to the first timing time, specifically: and updating the local time of the terminal into the first time correcting time to finish the terminal time correcting.
In some embodiments, as shown in fig. 3, the terminal timing method mentioned in the present application specifically further includes the steps of:
s210, acquiring a preset time difference threshold;
s220, judging the magnitude relation between the first time difference and the time difference threshold; if the first time difference is greater than the time difference threshold, step S110 is performed; if the first time difference is less than or equal to the time difference threshold, step S230 is performed;
and S230, updating the local time of the terminal according to the first standard time and the first time difference sent by the first service end.
In step S210, the terminal obtains a preset time difference threshold, where the preset time difference threshold refers to a time difference threshold corresponding to a request sent by the terminal and a response request received by the terminal from the server, and in practical application, the time difference threshold is generally set to 10 ms.
And step S110 is executed by judging the relation between the first time difference and the time difference threshold through step S220, if the first time difference is larger than the time difference threshold, namely, a first timing request is sent to a first service end, when the first time difference is larger than the time difference threshold, the terminal considers that the first service end is overtime, and after the terminal detects that the first service end is overtime, the terminal directly initiates the next first timing request to the service end without waiting for a response message sent by the first service end in order to enable the timing speed of the terminal to be faster. In practical application, the first time difference can be set to be 1 second, that is, the interval frequency of the terminal for requesting timing is set to be 1 second, so that the possibility of real-time timing of second level and a server side is realized, and even if data loss occurs in the middle, the terminal can initiate timing request again; if the first time difference is less than or equal to the time difference threshold, step S230 is performed.
In step S230, since the terminal detects that the first time difference is less than or equal to the time difference threshold, which indicates that the response of the first service end is not overtime, the time consumed by the terminal for acquiring the response of the first service end from the first service end is within the normal range, and the terminal can perform local time correction by using the first standard time sent by the first service end, specifically: and calculating the standard time corresponding to the time when the terminal receives the first standard time according to the first standard time and the first time difference sent by the first service end, and then updating the local time of the terminal to the standard time to finish terminal timing.
In some embodiments, as shown in fig. 4, the terminal timing method mentioned in the present application specifically further includes the steps of:
s310, sending a second time-correction request to a second server side and a third server side;
s320, receiving a second standard time generated by the second server according to the second time-correction request, and acquiring a second receiving time;
s330, receiving a third standard time generated by a third server according to the second time-correction request, and acquiring a third receiving time;
s340, obtaining a second correction time according to the second request time, the second standard time, the second receiving time, the third standard time and the third receiving time;
And S350, updating the local time according to the second correction time.
In step S310, in order to further improve the validity and accuracy of terminal timing, the present application considers that the second server and the third server are utilized to verify the accuracy and consistency of the time of the terminal, where the second server is one or more servers for providing standard time, and similarly, the third server is one or more servers for providing standard time, where the second timing request refers to a request that the terminal obtains standard time from the second server and the third server at the same time, for timing the local time of the terminal, the second timing request includes a second request time, and the second request time is a time that the terminal sends the second timing request to the second server and the third server at the same time.
In step S320, a second standard time generated by the second server according to the second time-correction request is received, and a second receiving time is obtained, where the second standard time is: and the second server receives the standard time corresponding to the second time when the second time correction request sent by the terminal is received, for example, beijing time, and the second receiving time is the time when the terminal receives the second standard time, that is, the time when the terminal acquires the response of the second server.
In step S330, a third standard time generated by the third server according to the second time-correction request is received, and a third receiving time is obtained, where the third standard time is: and the third receiving time is the time when the terminal receives the third standard time, namely the time when the terminal acquires the response of the third server.
In step S340, the second time correction time is obtained according to the second request time, the second standard time, the second receiving time, the third standard time and the third receiving time, and since the terminal respectively proposes the second time correction request to the second server and the third server, and the second server and the third server respectively respond to the second standard time and the third standard time to the terminal according to the second time correction request, a time error caused by communication can be generated, so that the second request time corresponding to the second time correction request is required to be recorded, the second receiving time when the terminal receives the second server response and the third receiving time when the terminal receives the third server response are recorded, and the second time error corresponding to the second standard time or the third standard time is obtained after adjustment by the second request time, the second receiving time and the third receiving time.
In some embodiments, as shown in fig. 5, the terminal timing method mentioned in the present application specifically further includes the steps of:
s341, comparing the magnitude relation between the second receiving time and the third receiving time; if the second receiving time is later than the third receiving time, obtaining a second correcting time according to the third time difference and the third standard time; if the second receiving time is earlier than or equal to the third receiving time, step S342 is performed;
s342, obtaining a second time difference according to the second request time and the second receiving time, and obtaining a third time difference according to the second request time and the third receiving time;
s343, judging the magnitude relation between the second time difference, the third time difference and a preset time difference threshold; if the second time difference is larger than the time difference threshold and the third time difference is smaller than or equal to the time difference threshold, obtaining second correction time according to the third time difference and the third standard time; if the second time difference is smaller than the time difference threshold and the third time difference is greater than or equal to the time difference threshold, then step S344 is performed; if the second time difference and the third time difference are less than or equal to the time difference threshold, step S344 is also performed;
s344, obtaining a second correction time according to the second time difference and the second standard time.
Through step S341, the magnitude relation between the second receiving time and the third receiving time is compared, if the second receiving time is later than the third receiving time, a second time difference is obtained according to the second request time and the second receiving time, and a third time difference is obtained according to the second request time and the third receiving time, if the second time difference and the third time difference are both less than or equal to a time difference threshold, a third timing time is obtained according to the third time difference and a third standard time, so that the terminal receives an earlier response, for example, the terminal receives the earlier response as a response of the third server, and the response is within the time difference threshold, the local time corresponding to the terminal is considered to be adjusted according to the response, and the other server, for example, the second server is used for further checking the timing accuracy of the terminal, if the second receiving time is earlier than or equal to the third receiving time, then step S342 is executed. Further, the second time difference is a time difference between a time when the terminal transmits the second timing request and a time when the terminal receives the second standard time, and the third time difference is a time difference between a time when the terminal transmits the third timing request and a time when the terminal receives the third standard time.
In step S342, a second time difference is obtained according to the second request time and the second receiving time, and a third time difference is obtained according to the second request time and the third receiving time. Here, two cases are divided, in which one case is that the second reception time is equal to the third reception time, specifically: the second receiving time corresponding to the response of the second server is equal to the third receiving time corresponding to the response of the third server, the time when the response is received by the terminal is consistent, the terminal simultaneously responds through the second server and the third server, and verification of accuracy and consistency of the acquired standard time is completed by the terminal. Alternatively, the second reception time is earlier than the third reception time, and further determination is required.
The magnitude relation between the second time difference, the third time difference and the preset time difference threshold is determined in step S343. If the second time difference is greater than the time difference threshold and the third time difference is less than or equal to the time difference threshold, it is indicated that the second server has too long response time, and at this time, it may be considered to verify the relationship between the third time difference and the time difference threshold, and if the third time difference is less than or equal to the time difference threshold, it is indicated that the third server has response time within a preset time range, and the terminal may consider the standard time returned by the third server, specifically: the second correction time is obtained based on the third time difference and the third standard time. If the second time difference is less than the time difference threshold and the third time difference is greater than or equal to the time difference threshold, step S344 is performed. If the second time difference and the third time difference are smaller than the time difference threshold, step S344 is also performed.

The method includes the steps that the second time difference is detected to be smaller than a time difference threshold value by the terminal, the third time difference is larger than or equal to the time difference threshold value, the second server response time is within a preset range, the second server response time is earlier than the third server response time, and the terminal can consider the standard time returned by the second server; in another case, the terminal detects that the second time difference and the third time difference are smaller than the time difference threshold, which means that the response time of the second service end and the response time of the third service end meet the time difference requirement, and because the response time of the second terminal is early, the terminal can consider the standard time returned by the second service end, and after the terminal determines the second service end, the terminal obtains the second timing time according to the second time difference and the second standard time sent by the second service end, wherein the second timing time is used for updating the local time of the terminal. In the embodiment of the application, whether the response efficiency is within the time difference threshold is judged according to the response time of different service ends, so that the response efficiency can be known in real time, for example, the terminal receives an earlier response, for example, the terminal receives the earlier response as the response of the second service end, and the response is within the time difference threshold, the local time corresponding to the terminal is considered to be adjusted according to the response, and the other service ends, for example, the third service end, are used for further checking the terminal timing accuracy.

In some embodiments, the terminal timing method mentioned in the present application specifically further includes the steps of: if the second time difference and the third time difference are both larger than the time difference threshold, the fact that the response time of the second server side and the response time of the third server side are too long are indicated, prompt information for prompting failure of timing is required to be generated at the moment, and a user is prompted to find a problem in an alarm mode.
