Material testing machine measurement and control system

Abstract

The invention discloses a material testing machine measurement and control system which includes a measurement and control host computer, a central processor, a wireless radio frequency transceiving module I, a wireless radio frequency transceiving module II, a photoelectric isolator I, a photoelectric isolator II, a sensor unit used for testing relative operation parameters of a material testing machine, a memory and a watchdog circuit connected to the central processor, a communication server connected to the measurement and control host computer, an LCD display screen and a printer. The measurement and control system is simple and high-efficient in circuit and is good in data transmission real-time property. The measurement and control system can achieve real-time automatic acquisition, analysis and treatment of test data and automatic control of an executing mechanism by means of a wireless communication technology and a sensor technology. The measurement and control system can effectively solve problems that a conventional measurement and control system is complicated in wire connection, is high in cost of investment and maintenance and is poor in system expandability and mobility performance.

Description

technical field [0001] The invention relates to the technical field of material testing, in particular to a measurement and control system for a material testing machine. Background technique [0002] Material science is the foundation of industry and manufacturing, and all industrial manufacturing must be based on material science. The development of various new materials and new products is inseparable from the testing of material properties. In the development of materials science, in order to explore and study the mechanical properties of new metals, alloys, compounds, polymer materials and composite materials, it is necessary to use materials testing machines and other instruments under various complex environments (such as high temperature, low temperature, high pressure and Corrosive medium, etc.) for accurate testing. Only after understanding the mechanical properties of materials can we design and manufacture reasonable and reliable products, and the electronic un...

AI Technical Summary

Problems solved by technology

[0003] Existing material testing machine measurement and control systems continue to develop towards automation and informatization, but PCI bus interfaces or USB interfaces are usually used for wired communication between their processors and host computers, which to a certain extent leads to cumbersome system wiring and investment and high maintenance costs, poor system scalability and mobility
