In addition, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application.

To enable those skilled in the art to use the present disclosure, the following embodiments are presented in conjunction with a specific application scenario "time update for sharing a single vehicle". It will be apparent to those skilled in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Although the present application is described primarily in the context of sharing time updates for a single vehicle, it should be understood that this is merely one exemplary embodiment.
It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
In a specific application scenario of the sharing bicycle, the sharing bicycle includes a vehicle-mounted chip, and when a data packet is sent to the server, time information is usually carried, the time information is generated according to a timer in the vehicle-mounted chip, the time of the timer of the vehicle-mounted chip may be advanced or delayed along with the extension of the service time, and in order to ensure the consistency between the time of the vehicle-mounted chip and the server, the vehicle-mounted chip is usually time-synchronized with the server periodically.
However, in some cases, the vehicle-mounted chip may lose the ability to directly synchronize with the server (e.g., enter a tunnel, and a network signal becomes poor), and at this time, the vehicle-mounted chip may not be synchronized with the server for a long time, and thus the time of the vehicle-mounted chip may be greatly different from that of the server.

It should be noted that, for convenience of description, the embodiment of the present application is described by taking a shared bicycle as an example, but it does not mean that the embodiment of the present application can only be applied to an application scenario of the shared bicycle, and in other application scenarios similar to the application scenario, for example, an application scenario for a wearable device (smart helmet, smart glasses, bracelet, and the like), a person skilled in the art can obtain technical solutions applicable to these scenarios without creative labor according to the time update technical solutions disclosed in the embodiments of the present application, and the embodiment of the present application belongs to a reasonable extension of the technical solutions disclosed in the embodiments of the present application, and shall also be within the scope of protection of the present application.

Based on the description of the electronic device 50 in fig. 2, the embodiment of the present application first describes a time updating method, please refer to fig. 3, and fig. 3 shows a flowchart of a time updating method provided by the embodiment of the present application, which can be executed by the first electronic device 10 in fig. 1, and includes the following steps:
step S101, when detecting that the preset condition is established, initiating a broadcast request of time update.
In this embodiment, the preset condition is that the local time of the first electronic device 10 may not be consistent with the time of the first server 20, and cannot be synchronized with the first server 20 normally, at this time, the first electronic device 10 sends a broadcast request for time update to obtain the time information from the second electronic device 30, so as to update the local time.
Step S102, a connection request sent by a second electronic device to a first electronic device based on a broadcast request is received and responded to so as to establish communication connection with the second electronic device, wherein the distance between the second electronic device and the first electronic device is within a preset distance range.
In this embodiment, since the first electronic device 10 and the second electronic device 30 both have the short-range communication function, the broadcast request sent by the first electronic device 10 can reach the second electronic device 30 within the preset distance range, taking bluetooth as an example, when the short-range communication technology such as bluetooth is adopted, the preset distance range is 10 meters, that is, on the premise of ensuring transmission quality and transmission efficiency, the working range of bluetooth is about 10 meters, and the bluetooth technology after increasing radio frequency power can work within a range of 100 meters, that is, the preset distance range is 100 meters at this time.
In this embodiment, there may be a plurality of second electronic devices 30 within the preset range, and the second electronic device 30 that receives the broadcast request will send the connection request to the first electronic device 10 only when the preset connection condition is satisfied. After the first electronic device 10 receives and responds to the connection request, the first electronic device 10 establishes a communication connection with the second electronic device 30, and further data exchange can be performed.
And step S103, receiving the time information sent by the second electronic equipment.
In the present embodiment, the time information is used to represent the local time of the second electronic device 30, the information of the synchronized local time, and the like.
Step S104, updating the first local time of the first electronic device according to the time information.
In this embodiment, the first electronic device 10 first determines whether the time information is valid information, and if so, updates its local time according to the time information.
According to the time updating method provided by the embodiment of the application, when the first electronic device 10 and the first server cannot perform time synchronization, the communication connection is established with the second electronic device 30 through the broadcast message, and the local time of the first electronic device 10 is updated based on the time information of the second electronic device 30, so that the local time of the first electronic device 10 in an offline scene is updated in time, and the abnormality of the processing flow of the first server caused by the time inconsistency between the first electronic device and the first server is avoided.
Referring to fig. 4, fig. 4 shows a flowchart of a specific method for updating the first local time of the first electronic device 10 in the time updating method of fig. 2 provided in the embodiment of the present application, namely step S104, where the step S104 includes the following sub-steps:
in sub-step S1041, a first synchronization time of the first electronic device, which is the latest time of time synchronization with the first server, is obtained.
And a sub-step S1042 of updating the first local time with the second local time when the second local time satisfies the preset time range and the second synchronization time is later than the first synchronization time.
In this embodiment, the time information sent by the second electronic device 30 may include a second local time and a second synchronization time, where the second local time is a local time of the second electronic device 30, and the second synchronization time is a time when the second electronic device 30 performs time synchronization with the second server 40 last time.
In this embodiment, it is determined whether the second local time meets the preset time range, so as to exclude a case that the second local time is obviously unreasonable, for example, the current time is 2019, but the second local time is 2018, 10 and 20, obviously, the second local time of the second electronic device 30 is obviously unreasonable, and the first local time cannot be updated by the unreasonable second local time.
In the embodiment, after excluding the time that the second local time is not obviously unreasonable, it is further required to determine whether the latest synchronization time (i.e. the second synchronization time) between the second electronic device 30 and the second server 40 is later than the first synchronization time, and if not, the first local time cannot be updated by the second local time.
It should be noted that there may be a plurality of second electronic devices 30, at this time, each second electronic device 30 may establish a communication connection with the first electronic device 10 according to the sequence of receiving the broadcast request, and at this time, the first electronic device 10 may have two processing methods: the method comprises the following steps: once a second electronic device 30 establishes a connection with itself, no connection request of other second electronic devices 30 is received; the second method comprises the following steps: the connection is established with each second electronic device 30 one by one, based on the first local time after the time information of the last second electronic device 30 that has established connection with itself is successfully updated, for example, the first electronic device 10 is device a, the second electronic devices 30 are device B and device C, time T1, device a updates the local time to time T1 and time T2 according to the time information of device B, device a updates the local time to time T2 according to the time information of device C, and finally, the local time of device a is time T2. If the time information of the device B and the device C cannot meet the update condition required by the device a (that is, the device B and the device C are not in the preset time range or the second synchronization time of the device B and the device C is not later than the first synchronization time), at this time, the device a may initiate the broadcast request again and continue to search for the second electronic device 30.
The time updating method provided by the embodiment of the application excludes the condition that the second local time is obviously unreasonable and the condition that the synchronization time of the second local time is earlier than the first local time, so that the second local time for updating the first local time is reasonable and updated latest, and the updated first local time is more accurate.
Referring to fig. 5, fig. 5 is a flowchart illustrating a specific method for detecting whether a preset condition is satisfied in the time updating method of fig. 2 provided in the embodiment of the present application, where at least the following three methods are detected whether the preset condition is satisfied, and fig. 5(a) is a flowchart of a first method: the first method comprises the following steps:

step S501, receiving a broadcast request of time update initiated by a first electronic device when a preset condition is detected to be satisfied, where a distance between the first electronic device and a second electronic device is within a preset distance range.
Step S502, a connection request is sent to the first electronic device based on the broadcast request, so that the first electronic device receives and responds to the connection request to establish communication connection with the second electronic device.
In the present embodiment, taking bluetooth as an example, the process of establishing the communication connection between the first electronic device 10 and the second electronic device 30 is as follows:
first, the first electronic device 10 pages (pages) the second electronic device 30 within a preset distance range in a frequency modulation manner.
Next, the second electronic device 30 scans (scan) external pages, i.e. page scan, at regular intervals, and responds to the external pages when the external pages are scanned, and at this time, a Link connection, i.e. an association of bluetooth physical ACL links (ACLs), is established between the first electronic device 10 and the second electronic device 30.
Third, after the ACL Link connection is established, the second electronic device 30 may initiate a channel connection request, that is, a connection of a Logical Link Control and Adaptation Layer Protocol L2CAP (L2 CAP).
Fourth, the second electronic device 30 uses a Session Description Protocol SDP (SDP) to query the hands-free service of the first electronic device 10, and obtains a channel number of the rfcomm Protocol based on serial (9-pin RS-232) emulation of the L2CAP Protocol. The second electronic device 30 will then initiate a connection request of the rfcomm protocol to establish a connection of the rfcomm protocol, thereby completing the communication connection between the first electronic device 10 and the second electronic device 30.
Step S503, sending the time information to the first electronic device, so that the first electronic device updates the first local time of the first electronic device according to the time information.

In sub-step S5022, a second type identifier of the second electronic device is obtained.
In this embodiment, the second type identifier is similar to the first type identifier, and is not described herein again.
And a substep S5023, when the first type identifier is consistent with the second type identifier, determining whether the connection request initiation condition is satisfied.
In this embodiment, taking the first electronic device 10 and the second electronic device 30 with bluetooth function as an example, the first type identifier is the same as the second type identifier, which may specifically mean that the feature field and the bluetooth service field in the first type identifier and the second type identifier are the same, that is, the second electronic device 30 and the first electronic device 10 are the same manufacturer. For the case that the second electronic device 30 and the first electronic device 10 are not of the same manufacturer, the second electronic device 30 does not continuously determine whether the connection request initiation condition is satisfied, and ends the processing, at this time, the communication connection between the second electronic device 30 and the first electronic device 10 is not established any more.
In this embodiment, the connection request initiation condition is a condition that the second electronic device 30 determines that the local time information can be sent to the first electronic device 10, so as to avoid that the second electronic device 30 sends inaccurate time information to the first electronic device 10, which may cause an error in updating the local time of the first electronic device 10.
And a sub-step S5024 of sending a connection request to the first electronic device when the connection request initiation condition is satisfied.

step S601, obtaining a second synchronization time of the second electronic device, which is the latest time of time synchronization with the second server.
Step S602, a second local time of the second electronic device is obtained.
Step S603, when a time interval between the second synchronization time and the second local time is greater than a second preset threshold, determining that the connection request initiation condition is satisfied.
In this embodiment, the second preset threshold may be set according to actual scene needs, for example, the second preset threshold is set to 1 hour, that is, the time synchronization with the second server 40 is performed within 1 hour last time, so that it can be ensured that the second local time is a relatively trusted time, the second preset threshold may be set according to the requirement of the actual application scene on the credibility of the time, when the requirement of the credibility is high, the second preset threshold is reduced, and when the requirement of the credibility is low, the second preset threshold is increased.
