Abstract

The present invention relates to a wireless network buoy system used for environment monitoring. The wireless network buoy system used for environment monitoring comprises a server equipment set and a buoy equipment set, the server equipment set comprises a network server and a remote terminal, and the network server comprises a database and a buoy agent. The buoy equipment set mainly contains a buoy main body, and the buoy main body comprises a cabin, a power supply module, a wireless communication unit, a main control and processor unit, an underwater sound modulator-demodulator and a sensor. The main control and processor unit comprises an underwater sound protocol stack and an acoustics remote control module, the underwater sound protocol stack especially contains a transparent layer and can support the cross-layer design, and the acoustics remote control module is allowed by the remote terminal to start and stop nodes and modify a communication protocol stack. The underwater sound modulator-demodulator adopts a multi-carrier and adaptive modulation coding technology, and the sensor can be connected with the main control and processor unit or the underwater sound modulator-demodulator. The wireless network buoy system used for environment monitoring of the present invention realizes the flexible and friendly interface and high communication transmission efficiency, and enables the performances of a conventional environment monitoring buoy system to be improved effectively.

Description

technical field [0001] The application relates to a wireless network buoy system for environmental monitoring, which is used in the technical field of water surface and underwater environmental monitoring of various water bodies. Background technique [0002] Most of the traditional sea surface or underwater environment monitoring is in the form of wired cables. In recent years, network nodes based on GPRS / TDMA and other types have appeared. However, their transmission rate and real-time information transmission are the bottlenecks in the development of various water surface monitoring technologies. [0003] After searching, domestic and foreign patents and documents related to wireless network buoy equipment involve satellite communication information transmission, wireless network information transmission, wireless local area platform information interaction, etc. The relevant literature is as follows: [0004] 1) Utility model patent "A remote monitoring system for chann...
