Embodiment Construction

[0039] Specifically, the process of remotely batch updating node firmware in the embodiment of the present invention is as follows figure 1 shown, including:

[0040] Step 11: The gateway node receives the firmware update command sent by the host computer and the ID of each selected node;

[0041] Step 12: The gateway node continues to issue the received firmware update command and the ID of each selected node until it monitors that all the selected nodes enter the firmware update mode within the set time period or when the set time period is exceeded, stop issuing the firmware update command and the ID of each selected node;

[0042] Step 13: The gateway node broadcasts the firmware update package packet by packet, monitors whether the nodes in the firmware update mode successfully receive the firmware update package, and once a node that fails to receive the firmware update package is found, it sends a return to work mode command to notify the node to return to work model....

Abstract

The invention relates to a method for remotely updating node firmware in a batched manner. The method for remotely updating the node firmware in the batched manner specifically includes the following steps that: a gateway node receives firmware update instructions transmitted by an upper computer and the IDs of selected nodes; received firmware update instructions and the IDs of selected nodes are continuously transmitted until all selected nodes enter a firmware update pattern in a set duration or the set duration is exceeded; and firmware update packets are broadcasted one packet by one packet, and whether the nodes under the firmware update pattern successfully receive the firmware updating packets is monitored, and once a node which does not successfully receive the firmware updating packets, a work pattern return instruction is transmitted to the node. With the method for remotely updating the node firmware in the batched manner provided by the invention, the failure of the update of node firmware can be timely found, and the node can be made to return to a work pattern instantly.

Description

technical field [0001] The invention relates to wireless sensor network technology, in particular to a method for remotely updating node firmware in batches. Background technique [0002] The wireless sensor network, which integrates sensor technology, information processing technology and network communication technology, is composed of a large number of sensor nodes distributed in physical space. With the help of different types of built-in sensors in the nodes, it detects different surrounding environments, including temperature, humidity, direction and speed of moving targets. and many other material phenomena. In various application scenarios, wireless sensor networks will inevitably be interfered by various aspects, such as mobile signals, electromagnetic waves, etc., resulting in packet loss, wrong transmission, etc. Most of these phenomena will lead to the failure of remote update node firmware. In the existing remote batch update node firmware method, after the gat...
