Buoyancy compensation type automatic multi-parameter vertical water quality data acquisition device and using method thereof

Abstract

The invention discloses a buoyancy compensation type automatic multi-parameter vertical water quality data acquisition device and a using method thereof and belongs to the technical field of water quality monitoring. The buoyancy compensation type automatic multi-parameter vertical water quality data acquisition device comprises an underwater monitoring device and an elevation and control device.By adopting distribution of a stepped motor and by virtue of buoyancy compensation of a buoyancy block, the torque of the stepped motor meets the distribution weight demand of the device, and the condition that the distribution and complete device is too large in size due to use of a large-torque motor is avoided. According to the device, the distance between the device and water bottom is measured in real time by an ultrasonic underwater distance measuring sensor and transmitted to a control module to be processed, the distribution depth of the device is controlled, and the device is prevented from contacting with the bottom. The water quality sensor module measures the water quality parameter and transmits the parameter to the control module to process, the water quality data change rateis analyzed, the device distribution speed is controlled, and the data is displayed and stored by a handheld terminal. The portability and practicality of the device can be improved by the data. Dataself-inspection of the sensor is realized by virtue of contrastive analysis of data of two water quality parameter sensors, and the acquisition process is intelligent.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring and measurement, and relates to a multi-parameter vertical water quality data acquisition device, in particular to a buoyancy-compensated multi-parameter vertical water quality data automatic acquisition device and a using method. Background technique [0002] Water is a basic natural resource and a strategic economic resource, a basic element for human survival, and a basic guarantee for social and economic development. With the rapid development of society and economy, under the dual pressure of excessive pollution discharge and over-exploitation of water resources, the problem of water environment pollution in my country has become more and more prominent. Understanding and mastering the state of the water environment is an important foundation and basic condition for the development of water environmental protection. Therefore, how to fully and accurately understand the state...

Problems solved by technology

However, its function is relatively single, the collection efficiency is not high, the operation is complicated, and it is easy to bottom out during the monitoring process. The acquisition of water quality data depends entirely on a single water quality sensor. Once the sensor fails, it will inevitably affect the detection data.

The patent "a multi-parameter water quality vertical dynamic data acquisition device for reservoirs" (public number: CN105044303A) invented by Han Min of Dalian University of Technology improved the multi-parameter water quality monitoring device, realized the semi-automatic monitoring of water quality parameters, and could The rate of change of various parameters of water quality adjusts the sampling frequency and the movement speed of the acquisition device to realize the online observation of the vertical distribution of multi-parameter water quality and improve the sampling accuracy and efficiency. However, the patent is still limited to the conceptual stage, and there are still complex equipment, step Incoming motor leads to limited lowering weight, easy bottoming during data collection, lack of sensor data self-inspection, etc.

[0004] Obviously, the existing water quality monitoring devices cannot balance high-precision and high-efficiency sampling with portability

It also does not have functions such as preventing the device from bottoming out and sensor data self-checking.
