A kind of shrub condensate water measuring device

Abstract

The invention provides a bush condensed water measuring device comprising a supporting vertical rod, the supporting vertical rod is vertically arranged, a test frame mounting platform is connected tothe top end of the supporting vertical rod, a test frame outer cover is connected to the test frame mounting platform, and a diversion grid is disposed on the test frame outer cover; a sensor mountingplatform is disposed on the test frame mounting platform; a weighing sensor is mounted on the sensor mounting platform; a semiconductor temperature control component is mounted on the weighing sensor, and a heat insulation component is mounted between the semiconductor temperature control component and the weighing sensor; a test surface temperature sensor is disposed on the semiconductor temperature control element; a leaf surface temperature sensor is used to measure the leaf surface temperature of a shrub; a controller includes a temperature controller, a weighing circuit and a power source, the test surface temperature sensor, the leaf surface temperature sensor and the semiconductor temperature control component are electrically connected to the temperature controller, and the weighing sensor is electrically connected to the weighing circuit. The shrub condensed water measuring device can accurately and continuously measure the amount of condensed water in the shrub in real time.

Description

technical field [0001] The invention relates to the technical field of research on condensed water in shrubs, in particular to a measuring device for condensed water in shrubs. Background technique [0002] Rainfall in the land water cycle system can be divided into two forms: vertical rainfall and horizontal rainfall. At present, the observation of vertical rainfall (rain, snow, hail, etc.) is relatively mature and standardized, and has a long history. As for horizontal rainfall (such as frost, dew, fog, rime, etc., also known as condensed water), it is often ignored by people because of its small occurrence, short duration, and difficulty in measurement. However, since the frequency of horizontal precipitation is far greater than that of vertical precipitation, and its total amount is large, it is of great significance for the study of water and heat balance in the SPAC (Soil-Plant-Atmosphere Continuum) system. Especially in arid ecosystems, condensed water, as an import...

AI Technical Summary

Problems solved by technology

However, the current existing measurement methods mainly have the following problems: 1. Due to the short occurrence time of condensed water, it is difficult to realize the real-time and continuous measurement

3. The measuring device is located outdoors and is easily affected by surrounding environmental factors

4. It is difficult to calibrate the traditional measurement sensor, and there are many uncertain factors
