Large-range evapotranspiration observation system

Abstract

The invention discloses a large-range evapotranspiration observation system. The large-range evapotranspiration observation system comprises two installation towers which are arranged in a north-south mode and used in a matched mode, wherein acquisition equipment, power source equipment, a lightning rod, a solar panel, a net radiation sensor, a soil heat flux sensor and a base with a vertical rod are fixed to the first installation tower, the base is fixed to a protective net sleeve, a three-dimensional wind sensor is fixed to the top end of the vertical rod of the base, a scintillator sensor receiving end, a four-component sensor and two shelter boxes with temperature and humidity sensors are fixed on the base; a lightning rod, a scintillator sensor transmitting end, a solar panel and power supply equipment are arranged on the second installation tower; and the scintillator sensor transmitting end is fixed on the protective net sleeve, and the axes of the scintillator sensor transmitting end and the scintillator sensor receiving end are on the same straight line, so that light beam focusing is kept. The invention provides a multilayer three-dimensional layout of the whole system, reliable data guarantee is provided for measuring evapotranspiration, and the large-range evapotranspiration observation system has the advantages of high integration level, convenience in installation and accurate and reliable measured values.

Description

technical field [0001] The invention relates to the technical fields of meteorological monitoring and ecological hydrological monitoring, in particular to a large-scale evapotranspiration observation system. Background technique [0002] Natural disasters, such as rainstorms, floods, droughts, tropical cyclones, etc., will bring great harm to human life and property. Under the influence of global climate change, extreme weather events in my country have increased significantly, and the probability of extreme disasters such as high temperature, drought, cold wave, rainstorm, flood, and earthquake has increased, and the suddenness, abnormality, and unpredictability of disasters are becoming more and more serious. How to effectively monitor natural disasters has also become a hot topic of research and discussion. [0003] Meteorological disasters are one of the primary disasters in nature. At present, meteorological disasters are monitored mainly through various means such as w...

AI Technical Summary

Problems solved by technology

For example, the existing weather stations have high requirements on the environment of the monitoring site, and the monitoring equipment has a large volume and weight, low integration, complex installation and requires professional technicians to debug and install, and is difficult to transport, which has brought great restrictions to meteorological monitoring.

[0004] The existing ecosystem evapotranspiration monitoring system has strict requirements on the environment and is difficult to adapt to complex environments. Especially after the power supply voltage is unstable or the power is cut off, it is easy to cause system interruption and cannot continue monitoring, which in turn affects the unattended environment. Continuous monitoring of evapotranspiration

The existing large-scale evapotranspiration observation system has the problems of low integration, complicated installation, and the inability of the sensor to present three-dimensional measurements, resulting in numerical deviations
