The invention relates to a low-power dissipation on-line collecting system and a collecting method based on backup redundant data. Temperature gathering nodes on each link are sequentially connected in serial communication from (m, N) to (m, 1), the collection of temperature data can be achieved without the arrangement of an individual wireless data concentrator, and the cost of the on-line collecting system is greatly reduced. Meanwhile, each temperature gathering node receives and stores temperature data detected by redundant nodes, and when a certain transmission route goes wrong due to the that a certain temperature gathering node goes wrong or is incapable of working normally due to low power, the temperature data of the transmission route can be transmitted through the transmission routes formed by other temperature gathering nodes to achieve the function of redundant data communication. When a certain temperature gathering node or certain temperature gathering nodes go wrong or cannot transmit data, the fact that the data transmission of other temperature gathering nodes is not affected is guaranteed, and therefore a large area of communication failure caused by the invalidation of a certain temperature gathering node can be avoided, and stability is good.
