Abstract
The utility model discloses a wood material density quick measuring instrument. The quick measuring instrument comprises a volume measuring module, a quality measuring module, a central processing module and a display and input module, and the working order of the four modules is reasonably arranged. When no object is placed on the quick measuring instrument, the central processing module does not collect data from the volume measuring module. Only when an object is placed on the quality measuring module, the central processing module transmits a data reading command to the volume measuring module. If one of the length, the width and the height data of a wood material is not collected, the central processing module alarms automatically, so as to remind working personnel to place the wood material more orderly. The wood material density quick measuring instrument adopts the contactless measurement mode, and combines with the development technique of an embedded singleship, thereby having the advantages of convenience, rapidness and high measuring precision.
