Measurement and control system and method for testing machine

Abstract

The invention discloses a measurement and control system and method for a testing machine, belonging to the field of measurement and control systems of testing devices and overcoming the defect of an embedded system measurement and control instrument of the traditional testing machine on the aspect of an analysis function, and solving technical problems of insufficient computing resources, troublesome development, difficulty in updating the testing standard and the like of analysis. The measurement and control system of the testing machine comprises a testing machine measurement and control instrument and a remote server, wherein the testing machine measurement and control instrument comprises a central processing module, a measurement and control executing module connected with the central processing module, a measurement and control end communication module connected with the central processing module, and a digital display module connected with the central processing module; the remote server comprises a server end communication module, a remote analysis module and a data cache unit; and mutual data transmission is carried out between the measurement and control end communication module and the server end communication module. The embodiment of the invention is applied to experiment devices such as a tension testing machine, a pressure testing machine and a universal testing machine.

Description

technical field [0001] The invention relates to a measurement and control system for testing equipment, in particular to a measurement and control system and a measurement and control method for pressure testing machines, tensile testing machines, universal testing machines and other equipment. Background technique [0002] The testing machine is mainly used to measure the physical properties of materials or products, such as the yield strength and tensile strength of steel; the testing machine is composed of a loading host and a measuring and controlling instrument. The measuring and controlling instrument is used for human-computer interaction operation. It can display the measured indication value collected during the test process, analyze the curve data of the test process, especially the loading curve, automatically calculate and analyze the mechanical indicators, and can also control the testing machine to perform mechanical tests. Embedded system measurement and contr...

AI Technical Summary

Problems solved by technology

[0004] 1. The resources of the embedded microcomputer system are limited, the chip speed is slow, the memory is small, the programming language is low-level, and there are many analysis functions, especially the curve analysis that requires a large memory and a large amount of calculation is not easy to implement, the development cycle is long, and debugging is troublesome. higher cost

[0005] 2. There are many test standards involved in various countries and industries, but a testing machine measurement and control instrument can only provide a limited number of analysis functions, which cannot well meet the specific test analysis needs of users

[0006] 3. The test standard is constantly being revised and revised, which often leads to changes in the calculation formula, and the original functional modules need to be upgraded, but most of the measuring and control instruments do not support upgrading, and a few can be upgraded, whether the user installs the update by himself or returns For manufacturers to upgrade, in addition to considering the upgrade cost, they also need to bear risks, and it is time-consuming
