Problems solved by technology

[0002] The problem with the actually used three-coordinate acceleration sensor measurement circuit is that three coordinates are measured sequentially. This method not only has a slow data sampling refresh rate, but also the acceleration acquisition on the three-dimensional coordinates is not obtained synchronously, and three-dimensional synthesis cannot be performed.
This is an extremely fatal flaw for a mechanical diagnostic system

Description

technical field [0001] The invention belongs to the field of on-line detection of mechanical equipment, in particular to a three-dimensional coordinate acceleration measurement circuit. Background technique [0002] The problem with the actually used three-coordinate acceleration sensor measurement circuit is that three coordinates are measured sequentially. This method not only has a slow data sampling refresh rate, but also the acceleration acquisition on the three-dimensional coordinates is not obtained synchronously, and three-dimensional synthesis cannot be performed. This is an extremely fatal flaw for a mechanical diagnostic system. The only way to make up for this defect is to design a measurement circuit that can quickly and synchronously measure the acceleration of the three-dimensional coordinates. Contents of the invention [0003] The object of the present invention is to provide a three-dimensional coordinate acceleration measurement circuit. [0004] The t...
