Embodiment Construction

[0022] The specific implementation of the real-time automatic measurement system for soil infiltration performance of the present invention will be further described in detail below in conjunction with the accompanying drawings, but it is not used to limit the protection scope of the present invention.

[0023] See Figure 1. The automatic real-time measurement system for soil infiltration performance of the present invention includes a rainfall or water supply device, a soil supply device for an underlying surface, a data acquisition device, an intelligent data processing system and a display. Among them, the intelligent data processing system is used to process the images acquired by the data acquisition device, and output the numerical value or curve or image of the soil infiltration rate to the display.

[0024] For rainfall or water supply systems, artificial simulated rainfall devices can be used under the conditions of no rainfall and flow production, and stable and unif...

Abstract

The invention relates to a soil infiltration capability measuring system; the soil infiltration capability real time automatically measuring system in the invention comprises a rainfall or water device, a underlying surface soil device, a data acquisition device, a data intelligent processing system and a display device; wherein the data acquisition device is used to acquire a runoff pushing coverage area image or a soil humidification area image and records the concrete time; the data intelligent processing system is used to process data to acquire the image acquired by the device and output the soil infiltration rate value, curve or image into the display device. The invention has the advantages of easy operation, convenient transportation and transference, low cost, big labor saving and big material saving; furthermore, the invention can swiftly and accurately acquire the measuring result with real time, is suitable for indoor measurement as well as countryside measurement and other occasions, is not limited to the terrain and has wide popularization and application value in the research fields such as hydrological process, crop water utilization, irrigation management and soil corrosion.

Description

technical field [0001] The invention relates to a system for measuring soil infiltration performance, in particular to a real-time automatic measurement system for soil infiltration performance. Background technique [0002] At present, rainfall and irrigation infiltration are the main sources of water replenishment in farmland. The infiltration rate, the total amount and the distribution of soil moisture content on the profile after infiltration are of great significance to the formulation of adjustment measures for the moisture status of farmland. [0003] At present, the measurement method of soil moisture infiltration usually adopts a double-ring infiltration instrument. During the measurement, the inner and outer rings hold water respectively at the same time, so as to simulate the soil moisture infiltration under the condition of rainfall and irrigation. When measuring, drive the inner and outer rings into the soil 10-15cm, and the outer ring must be concentric with t...
