Data acquisition system and method for soil detection

Abstract

The invention relates to a data acquisition system and method for soil detection. The control mechanism establishes a connection control relation with a moving mechanism, a lifting mechanism, a camerashooting mechanism and a clamping and releasing mechanism, and the control mechanism sends a moving instruction, a lifting instruction, a camera shooting instruction and a releasing instruction; themoving mechanism drives the lifting mechanism, the camera shooting mechanism, the clamping and releasing mechanism and a measuring mechanism to move integrally and horizontally according to the movinginstruction; the lifting mechanism drives the camera shooting mechanism, the clamping and releasing mechanism and the measuring mechanism to integrally move up and down according to the lifting instruction and enables the clamping and releasing mechanism to drive the measuring mechanism to be positioned above a settling cylinder; the camera shooting mechanism acquires an image of the settling cylinder containing the measuring mechanism according to the camera shooting instruction; the clamping and releasing mechanism fixes the measuring mechanism and releases the measuring mechanism into thesettling cylinder after receiving the releasing instruction, and the measuring mechanism carries out data measurement on soil in the settling cylinder. The instability of manual operation is reduced,a great amount of reading data is recorded at the same time, and the working intensity is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of soil detection, and in particular to a data acquisition system and method for soil detection. Background technique [0002] Soil mechanical composition (soil particle composition) is the percentage ratio of mineral particles in soil at all levels, which reflects the size and quantity of soil mineral particles, and affects the content, retention, supply and heat of water, air and nutrients in soil. It has important practical significance for the evaluation of soil basic properties and formation environment. In recent years, in the large-scale investigation of soil environmental conditions in China, it is necessary to measure the soil mechanical composition of a large number of samples. [0003] At present, the current domestic standards for the determination of soil mechanical composition are "LY / T 1225-1999 Determination of Forest Soil Particle Composition (Mechanical Compositio...

Problems solved by technology

[0005] Traditionally, in the data collection process, relying on manual operation, the horizontal position, vertical position and time of placing the density meter are not easy to control, especially when one person wants to read multiple samples at the same time, it often occurs that one loses sight of the other, and the reading time The error is so large that it is difficult to achieve consistency in the reading process

Especially the readings at 1min and 5min, and there is a time difference of more than ten hours between the readings at 8h and the beginning of the sample weighing in the experiment. Often the normal working hours of the day cannot complete a complete experiment, and it is possible to complete it only by working overtime. This greatly increases the work intensity and time of the experimenters
