Wireless sensor network signal synchronous collection and quasi-live transmission system

The invention discloses a wireless sensor network signal synchronous acquisition and on-time and real-time transmission method; wireless nodes in a wireless sensor network are divided into three kinds: a central node, a trunking node and a wireless sensor node, wherein, the central node is connected with a computer of a detection center for data transmission between the network and the computer; the trunking node and the central node are combined to a multi-hop chain type topological structure to realize a data long-distance transmission network; according to the information received from thetrunking node, the wireless sensor node selects to join to a detecting unit controlled by a certain trunking node in order to send the own acquired data to the trunking node. In addition, the wireless sensor network adopts vibration signals to sample an initialization mode before the beginning and sample an on-time and real-time data transmission mode after the beginning. The wireless sensor network is characterized in lo
