Store-and-forward node for monitoring lake water quality

Abstract

The invention relates to a store-and-forward node for monitoring lake water quality, which comprises a first interface group, a second interface group, a storage unit, a power supply module, a clock unit and a control unit, wherein the control unit is respectively connected with the first interface group, the second interface group, the storage unit, the power supply module and the clock unit, and is used for governing and controlling the operation of the whole store-and-forward node; the power supply module is respectively connected with the clock unit, the storage unit, the first interface group and the second interface group, and is used for providing a power source for the whole store-and-forward node; the clock unit is used for providing a clock source for the whole store-and-forward node and sending time sequence; the first interface group is used for connecting a monitoring device or an information acquisition device; the second interface group is used for connecting a transmission device; and the storage unit is used for storing received data. The store-and-forward node changes the single using method of a common water quality analysis meter, improves the using flexibility, and is convenient for secondary development.

Description

technical field [0001] The invention relates to the fields of information collection and environmental monitoring, in particular to a storage and forwarding node for lake water quality monitoring. Background technique [0002] In the past 20 years, the pollution and eutrophication of lake water environment in my country have become increasingly serious. All-round, multi-angle, and full-time monitoring of lake hydrology and water quality information is of great significance for controlling water pollution and preventing and controlling cyanobacteria blooms. At present, we mainly use satellite remote sensing and manual sampling methods to monitor the hydrology and water quality of lakes. However, the information obtained by remote sensing is very limited and cannot fully reflect the real situation; manual sampling generally uses the method of manual on-site water sample collection and laboratory analysis, which consumes a lot of human and material resources. So there are man...

Problems solved by technology

[0004] But even using these analyzers is not very convenient, because if the detection point is in the center of the lake, the experimenter has to go to the center of the lake every time to operate and use the analyzer

Although many online analyzers have integrated GSM modules to transmit data remotely, they still cannot play a role in blind areas (especially in the wild) where mobile signals cannot cover

In addition, because online monitoring is more complicated and started relatively late, even many products of large companies have some shortcomings, such as the inability to dynamically adjust the sampling period according to the solar power, etc.

Although these analyzers are simple to use and operate, they are not flexible enough and use a single method
