<P>PROBLEM TO BE SOLVED: To provide a digital processing method of measurement information and a noise reduction countermeasure inside a three-dimensional sensing stone. <P>SOLUTION: In the three-dimensional sensing stone incorporated with the triaxial acceleration sensor and PIC microcomputer, the triaxial acceleration sensor 1 and PIC microcomputer 2, which is an AD converter incorporated type one chip microcomputer, for processing the output signals from the triaxial acceleration sensor 1 are incorporated inside crushed stones. While multi-channel analogue data of the triaxial acceleration sensor 1 are automatically converted-outputted as the digital data using a ROM program in the PIC microcomputer 2, a multi-channel corresponding-type transferring protocol exclusive for the triaxial acceleration sensor 1 is constructed. By transferring the output data from the PIC microcomputer 2 to the outside through an optical cable not affected by electric noise, the noise in measuring triaxial acceleration is reduced. <P>COPYRIGHT: (C)2009,JPO&INPIT |
