Aiming at problems of big influence of human factors and poor controllability in process of torque wrench application presently

using wireless communication technology

micro signal processing technology

MCU technology

virtual simulation technology

design a type of torque test system based on Wi Fi wireless sensor networks（ WSNs） combined with virtual instrument. The system integrates torque measurement

signal acquisition

calibration

analysis

storage

display and forecasting and warning and achieve real-time accurate monitoring and effective control of multiple torque parameters. Simulation and measurement results show that measurement precision of the system can reach 0. 4 % FS

low power consumption

small size

good real-time performance

simple operation

stable and reliable

long time operation

and which is suitable for real-time monitoring of torque parameters in railway transportation

vehicle overhaul line

factories

and mines

etc.
