On-line water quality monitoring system

Abstract

The invention relates to an on-line water quality monitoring system, comprising a movable water quality monitoring node and a relay monitoring node which are floating on a water surface, and an ashore base station and a data center, wherein the movable water quality monitoring node and the relay monitoring node are used for monitoring water quality parameters and uploading the obtained water quality parameters to a cluster head node; the cluster head node fuses the collected data and reports to the ashore base station according to a specified format; the ashore base station uploads the data according to a monitoring query command of the data center; the data center is used for reconfiguring the monitoring data; and the movable water quality monitoring node and the relay monitoring node employ a random sampling strategy to sample and monitor the water quality. The life cycle of a conventional water quality monitoring method can be prolonged by the on-line water quality monitoring system.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to an online water quality monitoring system. Background technique [0002] Water quality is critical to the ecological environment, production and life. There are many problems with current water quality monitoring methods. The empirical detection method is very unreliable; although the laboratory detection has high precision, the real-time performance is poor, the process is complicated, the accuracy is not enough, and it is easy to cause secondary pollution; with the development of sensors and electronic technology, on-site water quality analyzers for lakes and other water bodies have appeared , although it has the characteristics of high precision and detachable combination of probes, it can detect water quality in real time, but it needs to be carried by people to the detection site when it is used, which consumes a lot of manpower. With the development of wi...

Problems solved by technology

In the existing water quality monitoring network, the sampling period is usually 15 minutes. Reducing the sampling frequency will affect the monitoring effect, but increasing the sampling frequency will increase the network traffic at an exponential level, greatly reducing the network life cycle.

Since the field water quality monitoring nodes are not easy to maintain and need to be unattended for a long time, the existing water quality monitoring network cannot solve this problem well
