Integrated water level and soil humidity monitor for over-wet ground surface environment

Abstract

The invention provides an integrated water level and soil humidity monitor for an over-wet ground surface environment. The monitor is rod-shaped as a whole and comprises a soil humidity meter and a water level indicator which are integrally connected, the monitor is inserted into a monitored area, an intelligent chip built in the monitor is respectively connected with the soil humidity meter and the water level meter through a circuit, conversion between water level measurement and soil humidity measurement is automatically achieved according to the condition whether water accumulates on the ground surface or not, a storage device receives data measured by two sensors, and the intelligent chip can achieve setting of a sampling period and unit conversion according to needs of a user. The integrated water level and soil humidity monitor for the over-wet ground surface environment can automatically achieve uninterrupted automatic monitoring and recording in dry, humidity and water logging processes of the ground surface environment, and can further prevent loss of soil humidity monitoring data in a long time sequence under the over-wet ground surface environment. The monitor is high in integration level and convenient to install and maintain, has a data backup function, can ensure stability of acquisition and storage of monitoring data during a long time and is suitable for completing measurement work under the over-wet ground surface environment.

Description

technical field [0001] The invention relates to a water level gauge, and also to a soil moisture meter, in particular to a monitoring instrument which integrates a water level gauge and a soil moisture gauge. Background technique [0002] The measurement of water level and soil moisture in the over-humid surface environment plays an important role in simulating and describing the hydro-ecological process in this special ecological environment. [0003] However, the over-humid surface environment has its unique features, that is, the same measurement point is sometimes submerged in water, sometimes there is no water accumulation, and the water level and soil moisture changes are uncertain, which brings great difficulties to the monitoring work. Difficulties. [0004] The current common practice is to set a water level meter and a soil moisture meter at the same measuring point at the same time to record the water level and soil moisture information respectively. For a monit...

Problems solved by technology

[0005] However, the existing equipment is not highly integrated, and the wiring is relatively complicated. Under extreme field conditions (freezing, corrosion, etc.), it is easy to damage the interface of the equipment, wiring or data box

Once damaged, the water level / soil moisture information within the monitoring period (several months or even a year) will be lost or cannot be used because the accuracy cannot be guaranteed. Great hindrance
