The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1: a floating station system for water quality and hydrological monitoring of small and medium-sized reservoirs, lakes, etc. is top-down, consisting of three levels: cloud computing center, central system platform, and floating station (including online monitoring instruments) Closely connected, the three levels are controlled by their own programs and connected to each other in the form of wireless communication. The computing center forms a top-down three-tier network system.

The simplest necessary arrangement of the central system platform of the present invention is a server computer with a data receiving, database and data processing platform. Various configurations are possible in actual implementation, and the working components shown in FIG. 1 can be arranged in this embodiment.
