Multi-parameter water quality vertical dynamic data acquisition device for reservoirs

Abstract

The invention discloses a multi-parameter water quality vertical dynamic data acquisition device for reservoirs and belongs to the field of water quality monitoring. The device mainly comprises a multi-parameter data acquisition module, a supporting frame, a stepping motor module, a micro-controller control module and a computer terminal. The multi-parameter data acquisition module comprises a data acquisition circuit, a signal transmission unit and a seal shell. The micro-controller control module comprises a single-chip microcomputer, a key circuit, a reset circuit and a crystal oscillation circuit and is used for controlling the stepping motor module to adjust ascent and descent of the acquisition module. The device has the functions of offsetting time delay, accurately monitoring the water quality parameter change rate and adjusting the sampling frequency. The multi-parameter water quality vertical dynamic data acquisition device for the reservoirs has the advantages that the sampling accuracy is improved, the data storage space is optimized, practicality and high efficiency are achieved, and the device is particularly suitable for stratified water quality monitoring of large-depth water such as the reservoirs.

Description

technical field [0001] The invention belongs to the field of water quality monitoring and relates to a multi-parameter water quality vertical dynamic data acquisition device for a reservoir. Background technique [0002] Water source reservoirs are engineering facilities for water storage and water supply, and water quality protection and management are the key nodes to achieve safe water supply. During the operation of the reservoir, the problem of water pollution has become more and more prominent. After the reservoir is built, most of the pollutants formed by rainfall runoff, human activities, atmospheric deposition and biological metabolic deposition in the reservoir will accumulate in the reservoir, affecting the water quality of the water body. Especially in Northeast China, water source reservoirs are large in scale, deep in depth, and run for a long time, and the water quality in the lower layer of the reservoir has deteriorated seriously. Observations have found t...

Problems solved by technology

However, its function is relatively simple, and the water quality monitoring device used does not have the ability to obtain the underwater conditions of the instrument, which may cause damage to the instrument, and the collection efficiency is not high, and it is mainly for the marine environment, and the price is as high as 40-50 Ten thousand RMB

[0004] Obviously, the existing water quality monitoring devices for water sources and reservoirs cannot provide researchers with data that truly reflects the vertical distribution of water quality conditions
