Description
Technical Field

The river course usually possesses the function of regional water supply, therefore, the safety guarantee of river course quality of water is an important work of river course management. The river water quality monitoring and early warning is a key task for river managers and plays a vital role in guaranteeing the safety of river water quality. Therefore, a high-efficiency, stable and low-cost river water quality monitoring and early warning means is sought, which is a key focus of related operation managers and researchers and has great significance in guaranteeing river water supply safety.
The river water quality monitoring and early warning mainly comprises two main parts, namely monitoring data acquisition and water quality early warning, and the water quality early warning is established on the analysis of a large amount of water quality parameter monitoring data. The conventional riverway water quality monitoring method generally comprises two categories of laboratory sampling detection and field monitoring, wherein the laboratory sampling detection gradually fails to meet the task of riverway water quality guarantee at the present stage due to the characteristics of slow analysis speed, complex operation, possible secondary pollution risk of samples and the like; the river water quality on-site monitoring has the advantages of real-time, reliability and quickness, so that the river water quality on-site monitoring has a better development prospect in the field of river water quality monitoring. In a conventional river water quality on-site monitoring method, a monitoring device with a single parameter is usually arranged at a fixed position. At present, two technical problems exist in water quality field monitoring: firstly, as the riverway is lengthened, the comprehensive monitoring and understanding of the riverway water quality condition are difficult to realize, the existing fixed measuring point water quality monitoring method cannot comprehensively reflect the water quality conditions of different positions and depths in real time, and the fixed-point sampling point of the patrol ship is adopted, so that the water quality monitoring result of any point is difficult to accurately obtain, and meanwhile, the fixed-point sampling point monitoring cost of the patrol ship is high, and the monitoring frequency is difficult to ensure; secondly, because the parameters reflecting the characteristics of water quality are more, generally, the water quality monitoring of a comprehensive system needs to involve various monitoring devices and cannot be completed through a water quality monitoring device with a single function, so that the comprehensive water quality monitoring work needs to be completed by installing various monitoring devices, a plurality of technicians are needed to participate, and the workload is quite heavy.
Aiming at the problems, the invention aims to provide an integrated device which can automatically, synchronously and automatically monitor various water quality parameters and can realize real-time monitoring and early warning of any coordinate and any depth of a river channel.
