Abstract: In order to solve the problem of testing and analyzing the running performance of elevators fast and accurately during the process of inspection and safety evaluation, an intelligent instrument for testing elevator's running performance was developed. Several sensors including tri-axial accelerometer and sound level meter are exploited to measure elevator's running signals and 32-bit embedded system is used to accomplish signal processing and numerical analysis. Then elevator's running performance parameters including jerk, acceleration, velocity, displacement, vibration and noise are obtained. The nonlinear error of tri-axial accelerometer is less than 0.1%, the relative deviation of frequency response is less than 1%, and the relative error of the sound level meter is less than 0.3%. Application results show that the instrument realizes convenient visual measurement and fast accurate analysis of elevator's running performance, which makes it a domestic solution for elevator's safeguarding.
