In regard to vehicle trembling recording and the abnormal inspection system and vehicle trembling recording and the abnormal

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for recording the trembling and detecting the fault of a vehicle that achieves safety operation of a rolling stock inexpensively.;SOLUTION: Vehicle modules 11 each including a 3-axis acceleration sensor are installed in the vehicles C₁-C_N of a train running on rail, and central monitor units 14 and 15 for monitoring acceleration of vehicles in the vertical, lateral and front/back directions measured by means of the 3-axis acceleration sensor through a communication line 16 connected with the vehicles modules 11 are installed in a cabin and/or a conductor room. Acceleration of each vehicle in the vertical, lateral and front/back directions is always measured and when an abnormal acceleration is not measured, maximum value, minimum vale and maximum P-P value of acceleration of a vehicle in the vertical, lateral and front/back directions are stored in a first memory every predetermined set time, and when an abnormal acceleration is measured, the real time waveforms of acceleration in the vertical, lateral and front/back directions are stored in a second memory for a predetermined time.;COPYRIGHT: (C)2009,JPO&INPIT
