Abstract (in Japanese) (See Japanese page) 
(in English) In line with the trend of digitization in society as a whole, the construction equipment industry is also digitizing its maintenance.
The measurement of crawler rotation speed, one of the maintenance tasks to check the performance of machines, has the problem of low safety during measurement.
In this study, we propose a technology to automate the measurement by
detecting the vibration during crawler rotation using a smartphone accelerometer sensor and identifying the fundamental frequency of the vibration.
As a result of the study, it was found that there is feasibility in automating the measurement
