<p><P>PROBLEM TO BE SOLVED: To provide a wireless magnetic field measurement device in a railway vehicle capable of promptly measuring a magnetic field in the railway vehicle. <P>SOLUTION: A wireless magnetic field measurement device in a railway vehicle simultaneously acquires spatial coordinates and magnetic flux density by being equipped with: (a) a probe with a controller including a triaxial acceleration sensor which measures acceleration, a magnetic sensor which measures the magnetic flux density simultaneously with measurement of the acceleration, and an A/D converter which performs digital conversion to data on the acceleration and the magnetic flux density, and a wireless transmitter which transmits the data to which the digital conversion is performed; and (b) a personal computer (PC) with a wireless receiver which receives the data transmitted from the wireless transmitter, and an integration circuit which integrates acceleration data of pieces of the data. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
