Problems solved by technology

[0003] In the prior art, when different nodes send broadcast messages on the same broadcast time slot of the same frame at the same time, data collisions may occur, resulting in the loss of broadcast messages, so that time synchronization between nodes cannot be achieved. Therefore, each broadcast Only one node is allowed to use the time slot, but this will lead to low utilization of the broadcast time slot, and it is impossible to ensure that the nodes of the entire multi-level network can achieve time synchronization

Abstract

The embodiment of the invention discloses a broadcast time slot determination method and device, equipment and a storage medium. The method is applied to a common node in a multi-level network, the multi-level network comprises a plurality of common nodes having at least one hop relationship with a central node, and the method comprises the following steps: when a first broadcast message sent by aprevious hop node is received, determining a second node level corresponding to the node according to a first node level included in the first broadcast message; determining a target broadcast time slot in all available broadcast time slots according to the second node level and a compression mapping algorithm; and sending a second broadcast message carrying the second node level on the target broadcast time slot, so that the next hop node of the node determines the corresponding node level and broadcast time slot according to the second broadcast message. According to the technical scheme ofthe embodiment, the utilization rate of the broadcast time slot can be improved, so that time synchronization of all nodes in the multi-level network is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method, device, device, and storage medium for determining a broadcast time slot. Background technique [0002] A multi-level network includes an access node and multiple ordinary nodes. Each ordinary node needs to communicate with the access node. In order to realize the time synchronization between each ordinary node and the access node, each network node needs to send a broadcast message in the broadcast time slot. . [0003] In the prior art, when different nodes send broadcast messages on the same broadcast time slot of the same frame at the same time, data collisions may occur, resulting in the loss of broadcast messages, so that time synchronization between nodes cannot be achieved. Therefore, each broadcast The time slot is only allowed to be used by one node, but this will lead to low utilization of the broadcast time slot, and it...
