Automatic data acquiring device and automatic data acquiring method for pressure tester

Abstract

The invention provides an automatic data acquiring device and an automatic data acquiring method for a pressure tester, and belongs to the technical field of data acquisition of pressure testers. The automatic data acquiring device comprises the pressure tester and a terminal computer, wherein the pressure tester comprises a main unit, an oil pump, an oil tank, an oil delivery tube, an oil return tube, a control cabinet, a pressure sensor and an electric oil return valve; and the control cabinet comprises an oil filter valve, a one-way proportional flow control valve, an acquiring card and a display plate. A full-automatic pressure testing mode is realized, so that a testing process is simple and standard, signals are acquired automatically, data are automatically converted, analyzed and processed, stability of flow of hydraulic oil in the pressure testing process is guaranteed, and then the validity and the authenticity of the data are improved.

Description

technical field [0001] The invention belongs to the technical field of data acquisition of a pressure testing machine, and in particular relates to an automatic data acquisition device and method of a pressure testing machine. Background technique [0002] At present, the pressure testing machine has been widely used in the detection of infrastructure construction in our country. It is used to test the compressive strength of building materials such as cement samples and components. But usually in the process of testing, it is necessary to manually open and close the oil delivery valve and oil return valve in the pressure testing machine, so that the pressure testing machine can work continuously, but the opening and closing time points are determined by human eyes. Judgment and manual operation; during the test process, it is necessary to manually monitor the change of pressure, manually record the pressure value and time, and manually analyze and process the result data; t...

But usually in the process of testing, it is necessary to manually open and close the oil delivery valve and oil return valve in the pressure testing machine, so that the pressure testing machine can work continuously, but the opening and closing time points are determined by human eyes. Judgment and manual operation; during the test process, it is necessary to manually monitor the change of pressure, manually record the pressure value and time, and manually analyze and process the result data; therefore, more human factors are involved in the test process, resulting in the authenticity of the test data The reliability is low, and whether the test operation process is standardized will directly affect the reliability of the data

It will eventually affect the quality of the project, and in serious cases will cause hidden dangers to the project, and even cause major losses
