Suspended self-balancing self-cruising water quality on-line monitoring device and monitoring and evaluating method

Abstract

The invention relates to a suspended self-balancing water area self-cruising water quality online monitoring device and a monitoring and evaluating method. The device comprises a suspended cabin main body, a communication and control system and a suspended carrying table capable of adjusting a self-balancing posture, suspension feet for driving the suspension cabin main body to perform self-balancing attitude adjustment, cruise or fixed-point suspension are arranged outside the suspension cabin main body, and the communication and control system is used for planning a W-shaped water area cruise path and sampling points according to the water area terrain, controlling the water sample detection device to perform online water quality detection along the sampling points, evaluating the water area water quality according to the online detection result and outputting the water area water quality. The device, the monitoring method based on the device, the evaluation method based on the monitoring method, automatic path and sampling point planning and precise positioning self-cruise monitoring are achieved, the position is stable in the monitoring process, and self-balance is not disturbed by water surface fluctuation; the method improves the monitoring and evaluation precision, greatly reduces the water area monitoring and evaluation cost, and is especially suitable for water quality monitoring and evaluation of different flowing water areas and water areas needing to be continuously monitored.

Description

technical field [0001] The invention belongs to the technical field of environmental water quality monitoring, and in particular relates to a suspended self-balancing water area self-cruising water quality online monitoring device and a monitoring and evaluation method.

Problems solved by technology

In the prior art, the suspended water quality monitoring device adopts the water quality monitor fixedly installed in the buoy main compartment as the core, and combines the power supply and data transmission equipment to form a fixed-point monitoring system; the existing water quality automatic online monitoring device and method are often applicable For fixed-point monitoring, for areas that require multi-point monitoring, multiple fixed monitoring devices are used for point monitoring, and water quality assessment is performed with the detection data of separate points; There are the following defects: (1) The water body in the water area has a certain degree of fluidity, which makes the fixed point monitoring and evaluation effect unsatisfactory. Single point detection is one-sided for water body evaluation, and Multi-point monitoring is not only costly and the monitoring data is relatively independent, the detection data of separation points is easy to cause evaluation errors. For waters that require multi-point continuous monitoring, it is difficult to accurately evaluate and reflect the overall comprehensive situation of water quality; The optimal sampling point and sampling quantity of topographical planning affect the adequate characterization of the water body and the applicability of the monitoring and evaluation methods; (3) the water surface of most water areas is not in a static state for a long time, and the real-time online analysis of the water body often needs to keep the water surface constant. Relatively stable, the existing suspension and / or self-cruising unmanned water quality monitoring devices lack water attitude control and position control structure, it is difficult to accurately locate, self-cruise and position stability, and the monitoring results will cause certain errors due to disturbance of the water surface; (4) It is difficult for monitoring communication to visually reflect the results of water quality monitoring and assessment in water areas, and to warn of exceeding water quality, which affects the rapid expression of water quality assessment, early warning monitoring and management efficiency
