Abstract
Stress testers are widely used in the field of engineering equipment such as mobile vehicles,large construction machinery and so on.At present,it is easy to encounter complex wiring,wire breakage,difficulty in mobile testing and other situations when using wired stress testing.This paper designs the general framework of the stress tester based on wireless transmission,including a signal acquisition device and a signal receiving device,and the two devices communicate wirelessly through ZigBee.It derives the voltage signal conversion equation for strain gauges.Then,key circuits such as power supply management module,signal amplification module,ZigBee wireless transmission module circuit are designed,and corresponding programs are designed using Arduino UNO R3 single-chip microcomputer.Finally,the structure of the stress tester is designed in 3D and the prototype is processed,and preliminary testing is conducted to verify the feasibility of the design scheme.关键词
