Floating environment monitoring device

Abstract

The invention provides a floating environment monitoring device. The device comprises a buoy float, a data acquisition and transmission unit, a safety warning unit, a cloud platform and a mobile terminal, wherein the outer surface of the buoy float is a metal plate; the buoy float is filled with a foam material; a plurality of monitoring wells are symmetrically distributed along the central axis of the buoy float; the data acquisition and transmission unit comprises a water temperature sensor, a turbidity sensor, a PH sensor, an integrated control cabinet, a Beidou wireless communication module and a solar power supply module; the safety warning unit comprises a solar navigation lamp; data acquired by the monitoring device is transmitted to the cloud platform in real time through the Beidou wireless communication module; and the cloud platform is used for displaying the result on the mobile terminal in real time after finishing simple analysis of the data. The monitoring device can adapt to a severe monitoring environment in which the water level changes greatly; an external power supply is not required; real-time automatic monitoring and demonstration of various water temperatureand water quality parameters can be realized; units outside the buoy float are detachable; and convenience is brought to transportation as well as repair and replacement of parts.

Description

technical field [0001] The invention belongs to the technical field of water environment monitoring, and in particular relates to a floating environment monitoring device. Background technique [0002] The purpose of water environment monitoring is to obtain the water temperature, water quality structure and its change law in the whole time period of the water area, which is widely used in ecological protection, environment, and water conservancy projects. Water temperature and water quality structure will affect the rhythm, reproduction, and habitat conditions of organisms in the river. The main impacts of water conservancy and hydropower project construction on the water environment are eutrophication of reservoirs, low-temperature water discharged by power stations in spring and summer, high-temperature water discharged in autumn and winter, and water temperature accumulation. The impact of water temperature on several aspects of aquatic ecosystems. Water environment mon...

AI Technical Summary

Problems solved by technology

Existing river water temperature monitoring systems mostly use fixed arrangement of thermometers, manual readings, and off-line methods, and have the disadvantages of high labor costs, large data collection intervals, and incapable of real-time sharing

The fixed arrangement of thermometers cannot adapt to the situation of large fluctuations in the river water level; the manual reading method requires a lot of manpower; at the same time, the existing river water temperature monitoring method cannot achieve real-time online display of data, and the timeliness is insufficient

[0004] In terms of online monitoring of water temperature currently used, there are some relatively mature products at home and abroad, such as the groundwater dynamic monitor of Diver in the United States and the HOBO water temperature data recorder. Poor impact resistance, easy to cause data loss, and cannot provide real-time water temperature data

The domestic online temperature measuring instrument is represented by the ZDR type produced by Hangzhou Zeda. The storage host and the probe are separated, and the connecting wire between them is easily damaged. The extended communication function is mainly used in the laboratory, and the power supply is also the limitation of its field application. condition

[0005] Although the real-time automatic monitoring system for power station tail water or river channel water temperature disclosed by CN103411701B has realized automatic monitoring, the sensor of the above-mentioned system has only a single temperature probe, which can only reflect the water temperature information of a certain depth, and cannot obtain the water depth information corresponding to the thermometer; The method cannot adapt to the situation of large changes in water level; the data collection time interval of the system is 0.5-24h, and the collected data is uploaded after a certain amount is accumulated, the sampling interval is large, the upload interval is long, and the data transmission is not real-time; the data of the system It is sent to the user terminal in the form of SMS, the sending interval is long, the sending cost is high, and the user cannot query the data independently, and the received water temperature data also needs to be sorted out by itself

Floating systems have not been used in real-time online monitoring of river water temperature, and the software support is not perfect. There has not yet been a river water temperature monitoring system with collection, analysis, diagnosis and control functions, and there is no real-time automatic monitoring and display of various water temperature and quality parameters. device or system
