Coupled river water quality and sediment health monitoring system and method

Abstract

The invention discloses a coupled river water quality and sediment health monitoring system and method. The coupled river water quality and sediment health monitoring system comprises an unmanned ship, a data transmission center and a terminal user application platform, wherein river sediment deposition on-line monitoring equipment, a river water quality on-line monitoring module and river water quality sampling equipment are carried on the unmanned ship, topographic data and part of water quality health index data at a measurement point are collected in real time, and the measurement data istransmitted to the terminal user application platform through the data transmission center; the data transmission center comprises a satellite system and a satellite system network management center,and is used for navigating the unmanned ship according to the physical coordinates of each measurement point provided by the terminal user application platform and transmitting the measurement data tothe terminal user application platform; and the terminal user application platform is used for determining the number of measurement points and the physical coordinates of each measurement point according to the known width and length of a river, and providing the measurement data collected in time by the unmanned ship and the measurement data obtained by analysis to the unmanned ship through thedata transmission module to perform early warning prompt.

Description

technical field [0001] The invention relates to the technical field of river water quality and sediment monitoring, in particular to a monitoring system for coupling river water quality and sediment health. Background technique [0002] Since the implementation of the river chief system, the long-term management of the river has been paid more and more attention. River management is not only to manage water quality, but also to ensure that the river has a certain amount of healthy sediment in order to form a good ecosystem. If the river bottom sediment is unhealthy, it will cause secondary release of pollution and continue to damage the effectiveness of river management. At the same time, since the river has a certain flood storage capacity, it is necessary to dredge the bottom mud to expand the river traffic from the perspective of urban waterlogging control. flood capacity. [0003] Monitoring is an important means of river management. In the past, water quality monitor...

Problems solved by technology

In the past, water quality monitoring and sediment monitoring in rivers were mostly manual sampling and analysis. Manual sampling and management of more than 40,000 rivers are clearly beyond the reach of labor-intensive methods.

In terms of river dredging, due to the lack of scientific dredging basis, wheel dredging is generally used, that is, dredging once every 7-10 years. However, this method is time-consuming and laborious, with an annual cost of hundreds of millions of yuan. The cleaned sediment is treated and disposed of face new problems
