Embodiment Construction

[0026] figure 1It is one of the schematic diagrams of field-level monitoring system for large-scale process industry equipment based on wireless sensor network. The system includes: a wireless sensor node 1 installed on the device for collecting device monitoring data, a backbone node 2 for relaying and transmitting data, collecting data, performing fault analysis on the data and importing the analyzed data into the enterprise LAN gateway3. After the wireless sensor node 1 is started, it will select the backbone node 2 with the closest distance as the parent node by adjusting the transmission power. Collect clusters. The collection time slot of each data collection cluster is determined through negotiation or allocation by the gateway 3 . In each collection time slot, the wireless sensor node 1 transmits the collected data to the backbone node 2 of the cluster in TDMA mode, and the backbone node 2 sends the collected data to the gateway directly or through the forwarding of...
