研究目的
Investigating the design and implementation of a low-power wireless sensor system with wireless power harvesting for monitoring oil pipelines to detect vibrations and transmit information efficiently.
研究成果
The designed low-power wireless sensor system with wireless energy harvesting effectively monitors oil pipeline vibrations, demonstrating the potential for extended system lifetime and improved practicality through energy-efficient design and wireless power supplementation.
研究不足
The study focuses on vibration detection and does not address other potential pipeline issues like corrosion or material problems. The power harvesting efficiency and protocol optimization require further study.
1：Experimental Design and Method Selection:
The system design includes sensor nodes for vibration detection, sink nodes for data forwarding, and a monitoring center. The focus is on low-power design, including wireless energy harvesting and transmission protocol.
2：Sample Selection and Data Sources:
Vibration sensors detect pipeline vibrations, and data is transmitted to sink nodes.
3：List of Experimental Equipment and Materials:
Includes SoC CC1110 as the main controller, passive vibration sensors, rechargeable lithium batteries, and a wireless energy harvesting module with Schottky diodes HSMS
4：Experimental Procedures and Operational Workflow:
