Multi-cylinder wetland evapotranspiration separation monitoring device

Abstract

The invention relates to a multi-cylinder wetland evapotranspiration separation monitoring device and belongs to the field of plant physiology, ecological monitoring and wetland meteorological hydrological measuring devices. The device comprises evapotranspiration measuring cylinders, a sensor data collecting unit, a central control unit, a remote transmitting unit, a water level adjusting unit and a solar power management unit. Pressure sensors fixed into water in the cylinders through triangular brackets are used for performing underwater in-situ monitoring, and separated combined monitoringis achieved according to a compensation relationship between the measuring cylinders. Through cooperation between the central control unit and other units, automatic timing acquisition, processing, storage and wireless transmission of evapotranspiration data can be achieved, and setting of initial values of water levels of the measuring cylinders can be automatically achieved at regular time. Through interaction with a remote side information management system, remote control over the device is achieved. Simultaneous monitoring of evapotranspiration of the cylinders is achieved without destroying the growth state of protophyte, the monitoring demands of intelligent automatic collection, storage and data transmission are met, and the device is suitable for various fields. The device has the advantages of being simple, high in stability and reliability, good in field adaptability, high in precision and the like.

Description

technical field [0001] The invention belongs to the field of plant physiology, ecological monitoring, and wetland meteorological and hydrological measurement devices, and relates to a multi-tube type wetland evapotranspiration separation monitoring device, in particular to the monitoring of evapotranspiration, water surface evaporation, and wetland evapotranspiration of aquatic plants in a wetland environment. A device for automatic separate combined monitoring and comparative research of soil vertical flux in the environment. Background technique [0002] Wetlands are widely distributed all over the world. They are the ecological landscape with the richest biodiversity in nature and one of the most important living environments for human beings. Together with forests and oceans, they are called the three major ecosystems in the world. Wetlands have huge environmental functions and economic benefits. In terms of ecological functions such as water conservation, water purifica...
