Design of Elevator Multi-Parameter Detector Based on Acceleration Sensor
On-site detection of car motion parameters,vibration comfort,braking performance parameters,abnormal vibration frequency,tilt angle and other parameters is of great significance to ensure the safe and stable operation of elevators.The traditional analog output acceleration sensor is difficult to realize the multi-function and multi-parameter detection requirements of elevator due to its large volume and low integration degree.Based on the micro-electro-mechanical system three-axis acceleration sensor and high-performance microcontroller,the elevator multi-parameter detector is developed.The detector including three-axis acceleration wireless measurement module and intelligent terminal application.Field application shows that the detector can realize elevator speed and acceleration measurement,car vibration comfort measurement,escalator step and handrail vibration comfort measurement,elevator braking parameter measurement,abnormal vibration source tracing and other functions,which can be widely used in elevator installation,maintenance,inspection,sampling,accident investigation and other test occasions.The design idea of the instrument based on microelectromechanical system acceleration sensor will provide an effective reference for the safety testing of similar electromechanical equipment.
