Problems solved by technology

[0004] However, when there are multiple devices, several devices detect that the air channel is idle at the same time, and then send data at the same time, resulting in packet loss
And when there are many devices, there is a situation where a certain device has been waiting because it detects that the channel is busy before each transmission, the transmission timeliness cannot be guaranteed, and the accuracy and efficiency of data transmission are low

Embodiment 1

[0023] figure 1 It is a schematic flowchart of a device synchronization method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of synchronizing device periods when multiple devices transmit data, and the method can be executed by a device synchronization device.

[0024] Before performing device synchronization, establish a device synchronization solution model:

[0025] Initially, when the device starts running, it is assumed that the transmission of the first data packet of the device numbered K and the first data packet of the device numbered K+1 conflicts, so the data transmission period of the K+1 device is adjusted; where , the starting point of the sending time of the first data packet of K device is , the starting point of the sending time of the first data packet of the K+1 device is .

[0026] According to the preset rules and the set period adjustment parameters, calculate the adjusted data sending period of K+1 devi...

Embodiment 2

[0066] figure 2 It is a schematic flowchart of a device synchronization method provided in Embodiment 2 of the present invention. This embodiment is further optimized based on the above embodiments, and the method can be executed by a device synchronization device. Such as figure 2 As shown, the method specifically includes the following steps:

[0067] S210. If it is determined within the preset time that the second device has not received the first data packet sent by the first device, then adjust the parameters according to the preset period and the time slice length of sending the data packet to determine the time period for the second device to send the data packet target time period.

[0068] Among them, before adjusting the unsynchronized first device and the second device into synchronous devices, it is necessary to preprocess all devices and set synchronization cycle rules for all devices, so that the devices can send data packets according to the synchronization ...

Abstract

The embodiment of the invention discloses an equipment synchronization method and device, equipment and a storage medium. The method comprises the following steps: if it is determined that second equipment does not receive a first data packet sent by first equipment within a preset time, determining a target time period of sending the data packet by the second equipment according to a preset period adjustment parameter and a time slice length of sending the data packet; determining whether the second equipment receives a second data packet sent by the first equipment according to the time slice length of sending the data packet and the target time period of the second equipment; and if so, determining the time point of the second equipment for sending the data packet next time according tothe data packet information of the first equipment so as to complete the period synchronization of the second equipment on the preset synchronization period time. By completing period synchronizationof the equipment, data loss when multiple pieces of equipment send data at the same time is avoided, and the data transmission efficiency and accuracy are improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a device synchronization method, device, device, and storage medium. Background technique [0002] With the development of communication technology, the amount of data transmission is increasing, and multiple devices may send data packets at the same time. The device can only be in one of the sending or receiving modes at the same time. If multiple devices send data at the same time, the sending device cannot receive the data sent by other devices, and the receiving device is difficult to receive completely due to the mutual interference of the data. data from either sender, resulting in data loss. [0003] In the prior art, in order to avoid data loss, the device checks whether there is data being sent by other devices in the channel before sending data. If there is data, the device does not send data at this moment, and waits for a period of time to try ...
