Description

The hydrology-water quality remote supervision system
Technical field
The utility model relates to rivers, lake and reservoir hydrology-water quality Remote Monitoring Technology field, and specifically, the utility model relates to a kind of hydrology-water quality remote supervision system.
Background technology
The hydrology, water quality monitoring are the important means that guarantees rivers, lake and reservoir Environmental security.The main task of hydrologic monitoring is to measure the situation that hydrographic features such as river,lake and reservior rainfall amount, water level, flow change naturally, it is a basis and previous work, be knowledge and the staff officer of flood-control and drought relief, its quality and precision will directly influence real-time and the accuracy of regimen information, influence the science of flood-control and drought relief decision-making.The conventional parameter of water quality monitoring is conductivity, temperature, pH, dissolved oxygen DO and nutrient concentration etc.The generation, development and the variation that focus on each parameter of the hydrology, water quality monitoring are monitored in real time and are analyzed, and provide the information foundation for carrying out the antifouling work of flood, preventing drought and preventing.Along with socioeconomic fast development, the hydrology, water quality information are constantly proposed new requirement, observation project and content constantly increase, and then observation method, method and monitoring technology research and development and application are proposed more and more higher requirement.
Traditional monitoring method is that main means are carried out environmental water quality monitoring by the artificial field monitoring record hydrology data of timing, fixed point with artificial spot sampling, Laboratory Instruments analysis.Classic method exists that the monitoring frequency is low, sampling error big, Monitoring Data is disperseed, can not in time be reflected defectives such as the hydrology, change of water quality situation, is difficult to satisfy the demand that government and enterprise carry out effective water environment management.In addition, human factor usually causes the delay of regimen and wrong judgement, gives and measures and control and brought certain trouble and inconvenience, all will cause very big waste on time and fund.
