The invention provides a bamboo board molding stamping machine computer control method. A first type of material starts to be added through the signals of a moisture detecting circuit, an ultrasonic distance measuring circuit and a color identification sensor. If the detected thickness is greater than or equal to the set value of 7 mm, a second type of material is added. If the detected thickness is less than the set value of 3 to 6mm, the second type of material and a third type of material are added according to 1:1. If the detected thickness is less than the set value of 1 to 2mm, the third type of material is added. If the detected thickness is less than the set value of 1mm, a product is directly acquired. A micro-controller carries out weighting summation on the signals of the sensor and detecting circuits, so as to determine the storage time of a stamped bamboo board. According to the invention, the use is convenient; the method can stop a stamping machine automatically, can automatically detect the thickness, color and moisture content of the stamped bamboo board, and can automatically judge the quality of the stamped bamboo board; repeated stamping during a reconstituted bamboo stamping molding process is reduced; the finished product yield is improved; and wasted bamboo slips are reduced.
