Abstract
The present invention discloses a node upgrading method and system in a mesh network. The node upgrading method in the mesh network comprises: performing the wireless firmware OTA upgrade by the first node according to the terminal instruction; simultaneously performing OTA upgrade on at least part of the second nodes in the mesh network by the first node using the broadcast channel after completion of the OTA upgrade, wherein the second node is a node other than the first node in the mesh network. Embodiments of the invention also provide a node upgrading system in the mesh network.
Claims13
A node upgrading method in a mesh network, characterized in that the method is applied to a first node in the mesh network, the first node is any node in the mesh network, and the mesh network includes N nodes, where N is a natural number greater than 1;
- the node upgrading method in the mesh network comprising:
- performing wireless firmware Over-the-Air (OTA) upgrade by the first node according to instructions from a terminal;
- simultaneously performing OTA upgrade on at least part of the second nodes in the mesh network by the first node using a broadcast channel, after completion of the wireless firmware OTA upgrade, wherein the second node is a node other than the first node in the mesh network.
A node upgrading method in a mesh network, characterized in that the method is performed by a second node in the mesh network, the second node being a node other than a first node in the mesh network, the first node being any node in the mesh network, and the mesh network including N nodes, wherein N is a natural number greater than 1;
- the node upgrading method in the mesh network comprising:
- the second node performing an OTA upgrade by receiving an OTA upgrade command sent by the first node using a broadcast channel;
- and
- when the OTA upgrade of the second node fails, the second node re-performing the OTA upgrade by re-receiving the OTA upgrade command.
A node upgrading system in a mesh network, characterized in comprising:
- a terminal, a first node and a second node, the first node being any one of N nodes included in the mesh network, and the second node being a node other than the first node in the mesh network, wherein N is a natural number greater than 1;
- the terminal being configured to communicate with the first node by sending an OTA upgrade instruction to the first node;
- the first node being configured to perform an OTA upgrade according to the OTA upgrade instruction from the terminal;
- the first node being further configured to, after completion of the OTA upgrade, simultaneously perform OTA upgrade on at least part of the second nodes in the mesh network using a broadcast channel;
- and
- the second node being configured to perform the OTA upgrade after receiving the OTA upgrade instruction sent by the first node using the broadcast channel.
