Embedded monitor for constant compensation of lysimeter underground water

Abstract

The invention discloses an embedded monitor for constant compensation of lysimeter underground water.The embedded monitor comprises an embedded controller, an order control module, a data collection module, a communication module, a working state indicating module, a fault alarm module, a power module, a water inlet / outlet electromagnetic valve, a water level sensor, a water replenishing and measuring sensor, an overflow drop counter, an RS485 bus interface and a GPRS wireless communication; the constant water level control, water replenishing and measuring measurement, data collection and communication, working state indication and fault alarm function of lysimeter underground water can be realized by computer technology, wireless communication technology, high-precision detection technology, etc. The data observing efficiency and data precision are greatly improved, the high automation and intelligent degree can realize unattended operation, so the embedded monitor has wide application prospect.

Description

Technical field [0001] The invention belongs to the technical field of agricultural, forestry and water conservancy engineering equipment, and particularly relates to an embedded monitor used for groundwater constant level compensation of a lysimeter. Background technique [0002] The groundwater constant level compensation of the lysimeter is an indispensable monitoring data in the calculation of water balance, and it is an indicator reflecting the utilization of water resources by plants. In order to quantitatively determine the impact of groundwater replenishment on the growth process of plants, it is often necessary to accurately control the constant groundwater level of the lysimeter and perform constant replenishment and drainage measurements. Domestic and foreign lysimeters are divided into weighing lysimeters and non-weighing lysimeters according to different water measurement methods. The weighing lysimeter is the weighing method. Its weighing system has a complex struc...

AI Technical Summary

Problems solved by technology

[0004] At present, there have been automatic control and monitoring devices for lysimeter systems, but these devices are basically controlled by single-chip microcomputers, which have relatively large limitations, weak expansion functions, poor compatibility with external access equipment, and it is difficult to realize unattended full automation. and the purpose of intelligent monitoring
