Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydrogeological monitoring, in particular to a soil bidirectional condensation water cantilever type automatic monitoring system. BACKGROUND

[0002] Condensation water refers to liquid water formed by the condensation of atmospheric water vapor and soil pore water vapor when the ground temperature and surface soil temperature reach the dew point. The condensation water is a component of soil water. The natural conditions such as the large diurnal temperature difference and the relative humidity of the air are important factors affecting the amount of condensation water. In arid and extremely arid conditions, such as in arid regions where water resources are extremely scarce, any supplementary water resources can have a positive impact on the ecological system. As a stable and continuous water resource, although the amount of condensation water is small, it plays a very important role in maintaining the stability of the ecological system in arid and semi-arid regions. Condensation water is an important source of water for some plants, insects, small animals, and biological soil crusts in arid environments, which can increase the germination rate of plant seeds and effectively reduce water loss due to soil evaporation. In addition, as a source of moisture, condensation water also plays an important role in maintaining the stability of sand dunes.

[0003] Currently, condensation water is mainly observed manually. However, condensation water is mainly formed at night and in the early morning. It is difficult to observe manually in the wild at night, and even in the high-altitude uninhabited areas of the northwest, there is no food and water, no communication signal or weak signal, and there are often protected animals and wild animals, which do not have the conditions for manual observation, resulting in the inability to obtain long-term and continuous field observation data with large errors. Even though manual observation experiments of condensation water have been carried out in different regions, although some achievements have been made, most of the observation time is short, and only the existence and measurement of condensation water generation time are proved. Due to the limitations of observation time and observation frequency, these observations are difficult to reflect the condensation water cycle law and conservation capacity of the monitoring area, leading to relatively slow progress in the efficient use of condensation water.

[0004] Therefore, on the basis of the existing manual observation of condensation water, how to provide a condensation water measuring device and real-time monitoring system suitable for without manual operation has become a problem to be solved by those skilled in the art. SUMMARY
