Wireless sensor network data aggregation system based on optical fiber power supply

Abstract

The invention relates to a wireless sensor network data aggregation system based on optical fiber power supply. The wireless sensor network data aggregation system comprises a rear-end monitoring unit and a wireless sensor aggregation node. The rear-end monitoring unit provides power supply for the wireless sensor sink node through an optical fiber, and the wireless sensor sink node receives monitoring information collected by the sensor nodes in the network where the wireless sensor sink node is located and transmits the information back to the rear-end monitoring unit through the optical fiber. According to the invention, an energy and data transmission channel is provided for the sink node of the wireless sensor network through one optical fiber, the system has the advantages of long transmission distance, flexible deployment, strong anti-interference capability and the like, and the application scene of the wireless sensor network is expanded.

Description

Technical field [0001] The present invention belongs to the field of wireless sensors, specifically relates to a wireless sensor network data aggregation system based on optical fiber power supply. Background [0002] Wireless sensor network is a sensor node with specific functions through the way of self-organization network, information collection of intelligent network, the purpose is to let the sensor nodes in the entire network to obtain and process useful information in the area, and a certain mechanism to send to the aggregation node, the data through the aggregation node processing after transmission to the back-end monitoring unit, to achieve the continuous monitoring and status measurement of regional goals. Wireless sensor networks have important scientific research value and wide application prospects, and have been widely used in China's national defense military, national security, aerospace, environmental monitoring, traffic management, medical rescue, manufacturin...

Problems solved by technology

[0003] The wireless sensor aggregation node is generally powered by batteries or long-distance power supply. When using battery power supply, it needs to be replaced regularly due to limited power. However, in many application scenarios, battery replacement is very difficult; when using long-distance power supply, it is necessary to design a dedicated Long-distance power transmission function modules, and long-distance wires are inconvenient to deploy, difficult to maintain, and weak anti-interference ability
