Description

A floating environmental monitoring device

technical field

The invention belongs to the technical field of water environment monitoring, and in particular relates to a floating environment monitoring device.

Background technique

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 monitoring is an important prerequisite for assessing the degree of impact of water conservancy and hydropower projects on the water environment, giving full play to its engineering benefits, and reducing the impact of unfavorable water environments.

There are various types of river water temperature, which can be divided into three types: mixed type, transitional type, and layered type. At the same time, the diurnal and interannual variation of river water temperature is complex, and full-depth and long-term monitoring is required to accurately understand its water temperature structure and change law. 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 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.

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. The impact resistance is poor, it is easy to cause data loss, and it 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.

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.
