AI Technical Summary

Benefits of technology

In this new device described earlier, the technical effect of this innovator lies in combining different functions together on a common platform called XYZXCUBE or CMOS technology. These technologies allow for precise control over all three dimensions - position, force, and straination levels – while collectively displaying data from these measurements. They have several benefits such as faster analysis speeds due to being able to integrate signals across multiple screens without having to wait for each screen individually before acquiring any results. Additionally, they use special materials like ferroelectric memory instead of traditional batteries, allowing them to store and process data even longer than usual. Overall, this novel device allows researchers to perform complex calculations quickly and accurately.

Problems solved by technology

This patented technical problem addressed by this patents relates to an improved way for researchers studying materials such as clay mineral samples during their drilling process or construction work without having them wait until they are done again afterward due to lacking any ability to show how well these tests were working properly over longer periods of times (such as months).

Embodiment Construction

[0030] The multi-window data acquisition instrument for rock and soil mechanics test is a comprehensive data acquisition instrument for multi-functional rock and soil mechanics test that integrates displacement, pressure and strain collection. It can complete the tensile, compressive, shear and point load of rocks. It is used for data collection of tests, soil deformation, shearing and other tests. It has four sets of LED display windows and one LCD display window. Combined with the switching button, 20 display windows can be switched and displayed. This machine has the characteristics of fast acquisition speed and high precision. It has a built-in lead-acid battery and a built-in battery management circuit. sensor and four strain input interfaces.

[0031] The instrument functions are as follows:

[0032] 1. MCU

[0033] The instrument uses three single-chip microcomputers:

[0034] 1. MSC1200, AD acquisition and debounce processing of stress and pressure, the collected da...

Abstract

The invention relates to a soil and rock mechanics feature test multi window data acquisition device. Four strain gages are sticking on the rock sample to form full bridge or half bridge output circuit that has four switches K1-K4. The output of every two bridge output circuit connects to the input end of an amplifier (5, 6). And the output end connects to the input of MCU (7). Two pressure sensors (8, 9) connect to power ground and connect to MCU (7). The displacement sensor connects to data working up chip (37) and signal transforming chip (18), which connects to signal transforming chip (20). The chip (20) connects to MCU (11). And MCU (11) connects to integration block (10) that is connected to 20 LED and key board, MCU (7), and MCU (12). MCU (11) and MCU (12) connect to LCD. The 20 LEDs forms four display window that each has five LEDs.
