DEVICE AND METHOD FOR MEASURING A PLURALITY OF POINTS

PROBLEM TO BE SOLVED: To provide a device for measuring a plurality of points which uses a plurality of measuring means to measure physical quantity while accurately synchronizing time to measure physical quantity by each measuring means. SOLUTION: The device for measuring the plurality of points is provided with a plurality of measurement nodes 2 and a host computer. The measurement node 2 is provided with an acceleration sensor 21, a central processing unit 23 and radio equipment 24. The central processing unit 23 is provided with a CPU side timer 25, and the radio equipment 24 is provided with a WLAN side timer 26. The WLAN side timers 26 in the plurality of nodes 2 are synchronized with each other. In sampling by the acceleration sensor 21, the sampling cycle is measured by the central processing unit 23. At that time, the central processing unit 23 measures the sampling cycle by referring to the time of the WLAN side timer, and then measuring time by the CPU side timer 25. COPYRIGHT: (C)2007,JPO&INPIT
