[0083] image 3 It shows the flow of the first embodiment of the vehicle time synchronization service method of the present invention. See image 3 , each step of the method of this embodiment is described in detail as follows.

[0084] Step S10: The time synchronization client establishes a real-time connection with the vehicle's full-time online system.

[0085] This step can be implemented in two ways, the first way is as Figure 6 Shown:

[0086] Step S100: the time synchronization client initiates a connection.

[0087] Step S101: the load balancing device schedules connections.

[0088] The load balancing device distributes the connection initiated by the time synchronization client to the corresponding connection server according to the load balancing policy on it.

[0089] Step S102: The connection server receives the connection. If the connection can be received, go to step S103; if the connection cannot be received, go to step S112.

[0090] Step S103: the tim...

Abstract

The invention discloses a vehicle-mounted time synchronization serving method and system; and the vehicle-mounted time synchronization serving system corrects and adjusts the time of a client of a vehicle-mounted device to be in a more accurate state through a time synchronization function. The technical scheme of the invention is as follows: the vehicle-mounted time synchronization serving system comprises a time synchronization client, a vehicle full-time online system and a time server, wherein the time synchronization client establishes real-time connection with the vehicle full-time online system and transmits network events establishing connection with the vehicle full-time online system to the time server of a cloud terminal; the vehicle full-time online system establishes communication link with the time server; and the timer server synchronizes time information to the time synchronization client after receiving the network events establishing connection and transmitted by the time synchronization client.

Description

technical field [0001] The invention relates to time synchronization technology, in particular to a time synchronization service method and system based on a vehicle real-time online system between a cloud and a client. Background technique [0002] Time on in-vehicle devices may become increasingly inaccurate over time, affecting the functionality of certain time-sensitive applications. [0003] Vehicle-mounted devices can use GPS devices to adjust time, but not all occasions have GPS signals, and vehicles cannot complete the time synchronization function without GPS signals. Contents of the invention [0004] The purpose of the present invention is to solve the above problems, and provides a vehicle-mounted time synchronization service system, which enables the time of the vehicle-mounted device client to be corrected and adjusted to a more accurate state through the time synchronization function. [0005] Another object of the present invention is to provide a vehicle ...
