在各种试验机中,往往都需要对试样所受负荷(力)进行测量、记录和控制。随着科学技术的进步和计算机的普及应用,对试验机的精度、自动化程度和体积的要求越来越高,要求具有智能化的功能,实现机电仪一体化。因此,研制微型计算机控制试验机用测力模板可以说是试验机测试系统的革命。传统的电子测力系统由负荷传感器、测量放大器及显示、记录仪表等组成(如图1)。在这里,计算机与测量系统工作在非在线的开环状态,仅对测量系统的输出进行数据采集和处理,而不参与系统参数的调节和控制。微机控制测力模板则要求计算机与测量
In a variety of testing machines, often need to test the load (force) to measure, record and control. With the advancement of science and technology and the popularization and application of computers, the requirements on the accuracy, automation and volume of testing machines are getting higher and higher, requiring intelligent functions to realize the integration of electromechanical and electrical instruments. Therefore, the development of microcomputer control test machine force measurement template can be said that the test machine test system revolution. The traditional electronic load cell system consists of load cell, measuring amplifier and display, recording instruments and other components (Figure 1). Here, the computer and measurement system work in a non-online open-loop state, and only the output of the measurement system for data acquisition and processing, and not involved in the regulation and control of system parameters. Computer-controlled force measurement template requires the computer and measurement
