Device for controlling mud sample manufacturing precise proportioning through computer and control method

Abstract

The invention relates to a device for controlling mud sample manufacturing precise proportioning through a computer and a control method. The device comprises the upper computer, a control unit and an execution mechanism. The execution mechanism is composed of at least one execution unit. The upper computer is connected with the control unit through a serial communication interface, a stepping motor is connected with the control unit through a stepping motor control driving circuit, and weighing sensors are connected with the control unit through weighing feedback circuits. The invention further relates to a control method for the device. An instruction is sent through the upper computer, so that the control unit controls the execution units independent of one another in the execution mechanism to feed material. The needed proportion in mud sample manufacturing is controlled through the computer, the material is automatically fed into a mixing pool of a mixer, labor intensity of a tester and test preparation time can be reduced, precision of the feeding proportion can be guaranteed, and the device and the control method have good application prospects for a test related with mud sample manufacturing in geotechnical engineering.

Description

technical field [0001] The invention belongs to the field of geological disaster model tests, and relates to a precise batching device and control method for making mud samples in landslide physical model tests. Background technique [0002] Landslides are one of the major geological disasters worldwide. With the continuous intensification of human engineering activities, landslide geological disasters are becoming more and more frequent. In order to effectively prevent and control landslides, scholars at home and abroad have conducted a large number of experimental studies on landslides, and landslide physical model tests are an effective research method. For the landslide physical model test, the production of the physical model is a key link. It is necessary to configure the mud samples according to the similar ratio of the materials. The accuracy of the mud sample ratio directly affects the quality and even success of the entire physical model test. [0003] Regarding t...

Problems solved by technology

However, there is no device or method suitable for automatic mud sample production and batching. The material holding device is not suitable for loading materials for mud sample production. It cannot independently control the feeding of various materials, and cannot prompt material shortage information during feeding. The fault tolerance is poor. limited precision

At present, the ingredients for mud sample production still rely on manual weighing and put them into the mixing tank. The main disadvantage is that the batching process is labor-intensive and the manual weighing error is large.
