IMPACT MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To measure and record impact by a simple device having no wiring run, and to read its records by means of wireless for processing them. SOLUTION: This detector 2 is formed out of an acceleration sensor detecting impact as acceleration, a recording part recording the acceleration detected by the acceleration sensor, and of a transmitter transmitting the data of the recording part. This impact measurement device 1 is formed out of a display unit 4 exchanging signals with the detector 2 by means of wireless, and of a judging device 5 analyzing the data of the recording part for the detector 2, received by the display unit 4 for judging the defective state of a measurement object and the like. The detector 2 can be mounted to the current collector of a train and measured data can be read by means of wireless.
