Embodiment Construction

[0082] see figure 1 , the low-power online acquisition system based on backup redundant data according to this embodiment includes: a data center controller and three data acquisition node links connected in parallel to the data center controller. The three links connected in parallel are sequentially numbered from 1 to 3, and the second link and the third link after numbering are sequentially arranged in a direction gradually away from the first link. From figure 1 It can be seen that each link includes 16 temperature acquisition nodes connected by serial communication, and each of the temperature acquisition nodes is set on a temperature measurement point, and the 16 temperature acquisition nodes are separated from the data center controller The links are numbered sequentially from 1 to 16 from the nearest link near end to the farthest link far end from the data center controller.

[0083] The temperature collection node (m, n) represents the nth temperature collection nod...

Abstract

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.

Description

technical field [0001] The invention relates to an online acquisition system and acquisition method, in particular to an online acquisition system and acquisition method with low power consumption based on backup redundant data. Background technique [0002] With the strengthening of the country's comprehensive strength, the government has been stepping up efforts to improve people's living standards year by year. Especially in recent years, under the leadership of the government, a large number of old communities have undergone collective heating transformation. After the collective heating is put into use, the collective heating company needs to monitor the indoor temperature of each household in the community in real time, so as to adjust the heating temperature at any time, which requires installing a temperature measurement module in each household during the collective heating transformation process And a communication module that transmits the measured temperature sig...
