Online lake water quality monitoring system based on internet of things

Abstract

The invention relates to the fields of applications of the internet of things technology, the wireless sensor network technology, the global positioning system (GPS) positioning technology and the GIS electronic map technology, and discloses an online lake water quality monitoring system based on internet of things. The online lake water quality monitoring system comprises a node monitoring device, a data video base station and a remote monitoring center; the node monitoring device is arranged in a lake to be monitored, and is used for monitoring the lake water quality and transmitting the monitoring data obtained from the monitoring to the data video base station through an ZigBee network; the data video data base is arranged in the lake to be monitored for transmitting the received monitoring data, and water quality information and video information which are collected by the data video base station are transmitted to the remote monitoring center through a mobile communicating network; the remote monitoring center comprises a GIS module, and is used for controlling navigation of the data video base station by remote means depending on water quality map information which is provided by the GIS module after receiving the monitoring data and all information, and for assisting to treat water quality of the lake to be monitored.

Description

technical field [0001] The invention relates to the application fields of Internet of Things technology, wireless sensor network technology, GPS positioning technology and GIS electronic map technology, in particular to an online lake water quality monitoring system based on Internet of Things, ZigBee wireless sensor network and GIS electronic map navigation. Background technique [0002] Lakes are an important carrier of surface water resources and an important factor in maintaining the health of the ecosystem. They have many functions, such as regulating river flow, developing irrigation, providing industrial and drinking water sources, multiplying aquatic organisms, communicating with shipping, improving regional ecological environment, and developing minerals. This function has played an important role in supporting economic and social development and maintaining the balance of the ecological environment. [0003] In the past 20 years, with the development of social econ...

Problems solved by technology

[0005] (1) Portable water quality monitors are used for manual sampling and laboratory analysis. This method cannot perform remote real-time monitoring of water quality parameters, and cannot well reflect the continuous dynamic changes of the water environment.

[0006] (2) Adopt an automatic monitoring system composed of a monitoring center and several monitoring sub-stations, which can realize automatic continuous monitoring and remote transmission of data, but it is necessary to lay cables and establish multiple monitoring sub-stations in advance, which is easy to damage the ecological environment of the monitoring area. And the monitoring range is limited, and the system investment cost is high

[0007] (3) Using remote sensing technology for monitoring, the monitoring accuracy needs to be improved, and the measurement is easily restricted by the topography

[0008] (4) Water quality monitoring technology using aquatic organisms can only reflect changes in water quality, but cannot find the source of harmful substances that cause water quality changes

[0009] Existing water quality monitoring methods have some shortcomings: for example, for water quality parameters in large-area waters, complex terrain waters, and waters that are difficult for people to reach, not only cannot meet the needs of real-time online monitoring, but also cannot effectively monitor the water environment in complex waters.
