Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
When uploading data, an electronic device often needs to determine the generation time of the data, so as to facilitate the subsequent query when an event generating the data occurs. For example, for the position data, only knowing the positioning time corresponding to each position data, a continuous track can be drawn to restore the real running track of the electronic device; for the alarm data, the electronic equipment can be timely and effectively treated based on the alarm data only if the alarm time corresponding to the alarm data is known. However, some electronic devices do not have a clock function, which may cause the electronic device to be unable to know the generation time of the data, which requires the electronic device to perform the time-checking operation in advance. Currently, the time of an electronic device is typically manually checked by a user before using the electronic device. However, this data transmission method is cumbersome, and in particular, for an embedded device without a man-machine interface, the operability is not high. Based on this, the embodiment of the application provides a data transmission method, a data transmission device, an electronic device and a computer readable storage medium, which can enable the electronic device without a man-machine interaction interface to realize automatic timing so as to avoid the transmission of data which is not timing. In order to illustrate the technical solutions proposed in the embodiments of the present application, the following description is made by specific embodiments.
The following describes a data transmission method proposed in the embodiment of the present application. Referring to fig. 1, the data transmission method is applied to an electronic device, and includes:
In the embodiment of the application, the electronic equipment can receive the data transmission instruction directly input by the user; alternatively, the electronic device may also receive data transmission instructions sent by other devices (e.g., servers); alternatively, the electronic device itself may generate the data transmission instruction periodically, and the manner of acquiring the data transmission instruction is not limited herein.
In the embodiment of the present application, the data transmission instruction points to the data to be transmitted currently, that is, the data to be transmitted. Meanwhile, the data transmission instruction also carries a transmission destination for pointing to a corresponding transmission object. That is, by the data transmission instruction, the electronic device can know which data is currently transmitted to which transmission object.
Based on the above, the corresponding data to be transmitted can be determined in the local storage space of the electronic device according to the data transmission instruction. It will be appreciated that the data to be transmitted by an electronic device is typically generated based on events occurring on the electronic device. Therefore, a piece of data to be transmitted corresponds to an event, and in general, the data to be transmitted includes event information and a time check mark of the event; the event information includes not only information generated by the event but also related time information (such as event generation time, etc.) of the event; the time check mark of the event has two states, namely checked and unchecked, wherein the checked related time information of the event completes the check operation, and the unchecked related time information of the event does not complete the check operation.
In this embodiment of the present application, before the electronic device transmits the data to be transmitted, it is first determined whether the time check mark of the event is not checked, so as to determine whether a check operation is further required. If the verification is not determined, jumping to execute step 105 to perform the verification operation; otherwise, if it is determined that the data is verified, it is known that the verification operation is completed, and step 104 may be skipped to directly transmit the data to be transmitted.
In the embodiments of the present application, there are typically one or more timers within the electronic device. When the electronic device is powered on, it will immediately initialize and start a timer inside it. In general, a timer counts seconds to indicate what second is currently the time after the electronic device is started, that is, how long the current time has elapsed from the start time of the electronic device. The electronic equipment can rely on the timer and a preset timing server to check the generation time of the event, so that the real time of the event can be obtained, and the real time is the target time.
And 106, replacing the event generation time in the data to be transmitted with the target time to obtain updated data to be transmitted.
In this embodiment of the present application, the electronic device may replace the event generation time originally carried in the data to be transmitted with the target time obtained in step 105, so that the data to be transmitted also carries the real time when the event is generated, which is convenient for the subsequent receiver (i.e. the transmission object) of the data to be transmitted to better process the data to be transmitted.
In some embodiments, the step 104 may specifically include:
In this embodiment of the present application, for an electronic device, once an event that needs to be reported is generated, a timer may be read immediately, and the read timing result is the first time generated by the event, which is used to indicate the time period from when the electronic device is started to when the event is generated.
In this embodiment of the present application, the electronic device should have a networking function, and may establish a communication connection with a preset server, for example, a cloud server such as a timing server and a data server. Thus, after the event occurs, the electronic device may send a timing request to a preset timing server, which refers to a server having a function of checking time, to perform a timing operation. The timing server may be, for example, a NTP (Network Time Protocol) server or a global positioning system (Global Positioning System, GPS) server, etc. The time synchronization of the electronic equipment and the time correction server is realized by providing the accurate current time for the electronic equipment through the time correction server, and the accurate current time is the time correction time returned by the time correction server. In general, the timing time obtained by the electronic device is expressed in the time format of universal coordinated time (Universal Time Coordinated, UTC), that is, xx is a fraction of xx seconds. In order to keep the unit of the first time unified, the electronic equipment processes the time correction moment, and converts the time correction moment into a time length of 0 minute and 0 seconds from 1 month 1 day 0 time 1 month 1 day 1970 through a preset second time conversion function, wherein the time length is in seconds, and a conversion result is the second time. The second time is considered to be a time stamp of the time of the school time, and the concept of the time stamp is the number of seconds elapsed since 1 month 1 in 1970 (midnight of UTC/GMT), irrespective of leap seconds. For example only, the second time transfer function may be a time function in a standard C library, which is not limited herein.
In the embodiment of the application, when the timing is successful, that is, when the timing moment fed back by the timing server based on the timing request is received, the timer is read again. For ease of understanding and computation, the data interaction of the electronic device with the timing server is considered to be very short lived; that is, although the transmission of the timing request, the feedback of the timing time and the operation of reading the timer again occur sequentially, since the occurrence speed is very fast, the three operations are completed in almost one instant, and thus, it can be regarded as being completed at the same time approximately; that is, it is approximately considered that all three occur at the timing point. Based on this, the result of the timing obtained by reading the timer again in this step can be regarded as a third time, which can be used to represent the duration from the start of the electronic device to the timing moment. That is, the electronic device obtains two times, the second time and the third time, respectively, based on the timing operation.
It is understood that the first time, the second time and the third time may be stored in the time related information of the event. That is, the event information includes time-related information of the event, and the time-related information of the event includes a first time, a second time, and a third time of the event.
In this embodiment of the present application, the electronic device may subtract the third time from the second time and add the first time to obtain a time stamp of the event, that is, a time length of 0 minutes 0 seconds from 0 minutes 0 seconds of 1 month 1 day in 1970 to the time of generating the event, so that a real time (expressed as a specific time) of the event generated can be determined based on the time stamp of the event generated, specifically, the time stamp of the event generated is converted by a preset first time conversion function, and a conversion result is the real time of the event generated expressed by UTC.
As described above, the time correction operation is understood as an operation completed at one instant, and referring to fig. 3, fig. 3 shows an illustration of the first time, the second time and the third time on the same time axis, where T1 is the first time, T2 is the second time, T3 is the third time, and t2—t3+t1=t. As can be seen from fig. 2, T is the time period from 1970, 1, 0 minutes, 0 seconds to the occurrence of the event, and after converting T into UTC time, it can be known how the event is generated in what year, month, day, time, minutes, and seconds. It should be noted that, the embodiment of the present application does not limit when the electronic device performs the timing operation; that is, any time may be selected to perform the timing operation to obtain the second time and the third time after the event is generated, which is not limited herein.
In some embodiments, when an event is generated, the electronic device further records a time check mark and time information of the event in a space in which the event can be saved when the event is powered down, wherein the time check mark defaults to a preset first value (for example, "0"), and the time information defaults to a first time read based on the event. In practice, the time check flag may be considered as a flag (flag) to indicate whether the time information of the event has been timed. After the electronic device has obtained the target time generated by the event, the time information of the event can be updated to the corresponding target time, and the time check mark of the event is updated to a preset second value (for example, 1) to indicate that the time information of the event has been calibrated. It should be noted that when a plurality of events are generated, the events are sequentially recorded in the power-down storable space according to the sequence from the early to the late of the generation time of the events; that is, the first generated event will be recorded first.
It can be seen that, through the embodiment of the present application, after a data transmission instruction is obtained, an electronic device determines data to be transmitted according to the data transmission instruction, where the data to be transmitted includes event information and a time check mark of an event, and determines whether the time check mark of the event is non-checked, if yes, checks the generation time of the event to obtain a target time of event generation, then replaces the event generation time in the data to be transmitted with the target time to obtain updated data to be transmitted, and finally transmits the updated data to be transmitted to a transmission object in the data transmission instruction. According to the scheme, whether the data to be transmitted are calibrated or not is determined through the time check mark, for the data to be transmitted which are not calibrated, the electronic equipment can obtain the target time of event generation through calibration, and the event generation time corresponding to the data to be transmitted is replaced by the target time and then transmitted, so that the fact that all data transmitted by the electronic equipment are calibrated can be guaranteed, and a transmission object can process corresponding events in time.
