Ubiquitous sensor network system for remotely managing software of node, and its method

摘要

An ubiquitous sensor network system for remotely managing software of node and a method thereof are provided to solve the troublesomeness for downloading the software directly from the directly collected nodes by supplying the ROM(Read Only Memory) files remotely to nodes and managing the power of nodes by groups additionally. Each node receives a reset command for downloading, and establishes a flag in its flash memory for downloading and resets each node itself(204). Each node downloads a ROM file of the software from a management node(207). Thereafter, each node establishes the flag in its flash memory in order to operate normally and resets each node itself(208). Thereafter, each node controls its power according to a power control command received through the management node for managing itself. When generating an error in the program of one node out of multiple nodes, the ROM file of the software is downloaded into the node having the error. When the software of a development personal computer is corrected and then the whole ubiquitous sensor network system is updated, the ROM file of the program is downloaded into each node.
