Abstract: A node data transmission method, which pertains to the field of information technology, wherein in order to solve the problem of rationally processing the relationship between data collection and data transmission among multiple radio-frequency charged nodes, two neighboring nodes are synchronously awakened by a time synchronization method, and after the two neighboring nodes are time synchronized and awakened, the node determines data cache thereof and performs a corresponding node role conversion, and the effect thereof is reasonable use of the electricity.

Abstract: The building stress balance monitoring system of the passive sensor network, relating to the technical field of information, and aiming to solve the problem of making the pressure sensor easier to be charged in building stress monitoring. The system includes plurality of nodes arranged in the same building surface of the building or arranged in the supporting surface of the bridge; each node mainly consists of the pressure sensor module, the radio frequency signal acquisition module, and the network module; the sensing surface of the pressure sensing module acquires building pressure information and transmits same to the pressure sensor module; the pressure sensor module receives electric energy provided by the radio frequency signal acquisition module, and converts the pressure information into data, which can be uploaded to the network through the network module. The effect of making the pressure sensor easier to be charged is achieved.
