Embodiment 1

[0037] In this embodiment, wireless data communication is realized by a data sending end and a plurality of data receiving ends, to ensure the data synchronization of a plurality of data receiving ends, the data sending end and a plurality of data receiving ends can adopt bluetooth, local area wireless network (WiFi ) or mobile wireless network for wireless data communication.

[0038] figure 1 It is a flow chart of a data synchronization method provided by Embodiment 1 of the present invention. This embodiment is applicable to data synchronization, and the method can be executed by a data synchronization device, such as figure 1 Said, the method specifically includes the following steps:

[0039] Step 110, regularly acquire data packet groups.

[0040] Wherein, the data packet group includes multiple data packets. The data packet group carries the group number, and the data packet carries the packet sequence number; each time a data packet group is sent, the group number i...

Embodiment 2

[0052] figure 2 It is a flowchart of a data synchronization method provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the method includes the following steps:

[0053] Step 210, when the data packet broadcast by the data sending end is received, the number of data packets contained in the data packet group where the data packet is located, the sending interval of the data packet, the data sending time and the packet sequence number are obtained.

[0054] Wherein, the data packet is one of the data packets in the data packet group. The sending interval of the data packet is set by the data sending end, for example, it is set to 625us. The data sending time can be understood as the moment when the data sending end sends the data packet. The packet sequence number is the sequence number of the data packet in the data packet group.

[0055] Optionally, after receiving the data packet broadcast by the data sending end, it also includes: obtaining t...

Embodiment 3

[0067] Figure 4 It is a schematic structural diagram of a data synchronization device provided in Embodiment 3 of the present invention. The device is set at the data sending end, such as Figure 4 As shown, the device includes:

[0068] The data packet group acquisition module 410 is used to obtain the data packet group regularly; wherein, the data packet group includes a plurality of data packets;

[0069] The data packet sending module 420 is used to send a plurality of data packets in the following manner: according to the ordering of the data packets, a data packet is broadcast every set duration, so that multiple data receiving ends receive the data packets; wherein, the data packets carry data send time.

[0070] Optionally, the data packet group carries a group number, and the data packet carries a packet sequence number; each time a data packet group is sent, the group number is incremented by 1.

Abstract

The embodiment of the invention discloses a data synchronization method and device, equipment and a storage medium. The method comprises the following steps: when a data packet broadcasted by a data sending end is received, acquiring the number of data packets included in a data packet group in which the data packet is located, a sending interval of the data packet, data sending time and a packet sequence number; determining data output time according to the number of the data packets, the sending interval, the data sending time and the packet sequence number; and synchronously outputting the data packet according to the data output time. According to the data synchronization method provided by the embodiment of the invention, the data output time is determined according to the number of the data packets, the sending interval, the data sending time and the packet sequence number, so that a plurality of data packets contained in the data packet group can be ensured to be synchronously output at the data output time, and a plurality of data receiving ends can be ensured to synchronously output the data packet group at the data output time; the number of hosts is not limited, the synchronization error is low, and the communication timeliness is good.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a data synchronization method, device, device, and storage medium. Background technique [0002] In the field of wireless communication, it is a common application scenario for a slave to synchronize and communicate with multiple masters. If the traditional long connection method is used, the number of hosts will be limited; if the number of hosts is large, the timeliness is poor and synchronization cannot be guaranteed. Contents of the invention [0003] Embodiments of the present invention provide a data synchronization method, device, equipment, and storage medium, which can realize data synchronization of multiple data receiving ends, not only does not limit the number of hosts, but also has low synchronization errors and good communication timeliness. [0004] In the first aspect, the embodiment of the present invention provides a...
