Development and Application of Vibration Comfort Detection Device for Escalator Based on MEMS Acceleration Sensor

Abstract Vibration comfort is an important indicator for evaluating escalator riding experience. The measuring principle of vibration step and armbands was analyzed. calculation methods acceleration extraction, frequency meter weight, root mean square (RMS) vector sum were summarized. A wireless triaxial data acquisition module developed based on micro-electromechanical system (MEMS) sensor, MCU high-speed WIFI module, a detection application (APP) the Android operating developed. calibrated device applied to field test. results showed that maximum RMS average armband both sides can be quickly calculated, level divided, which provided reference equipment maintenance.
