The independent analyzing spot synoptic diagram of two dimensional laser scanning appearance such as Fig. 1 drive two dimensional laser scanning appearance rotation sweep point synoptic diagram such as Fig. 2 through the gauge head whirligig.
Like Fig. 1, the two dimensional laser scanning appearance is installed in the stock ground heap and gets on the material equipment, through moving of equipment; Two-dimensional scanner obtains the profile data of stockpile on each position and calculates cross-sectional area S1 in different position scanning; Through the measurement of shift length, draw the distance L 1 between adjacent two sections again, just calculated the material stack volume V1=S1*L1 between adjacent two sections; When the heap taking equipment is accomplished after advancing on the stock ground, by scanned stockpile cumulative volume V=V1+V2+V3++Vn.Through known intensive P, just can obtain the general assembly (TW) M=V*P of stockpile again.
Fig. 1 China and foreign countries square frame is the border, stock ground; Interior square frame is the maximum border of stockpile when piling with material in the stock ground; The dot matrix area domain representation is only got advancing of material equipment through heap and is driven the zone of two dimensional laser scanning appearance scanning, and stockpile is failed to cover fully in this zone, makes inventory procedure exist and measures the blind area.
Fig. 2 China and foreign countries square frame is the border, stock ground; Interior square frame is the maximum border of stockpile when piling with material in the stock ground; The scanning area of dot matrix area domain representation material field digitizing check system; This zone has covered stockpile fully, and the semicircle scanning area of the left and right sides drives two dimensional laser scanning appearance rotation sweep through a side whirligig and forms, and whole inventory procedure does not exist measures the blind area.
But because the design of heap taking equipment self can not arrive the two ends in stock ground, the subregion two dimensional laser scanning appearance at these two ends sweep less than, so just can not reach the purpose of making an inventory automatically in the complete feed field fully.
The invention enables scanning area to become one by a sweep trace is the circular scan face of diameter with former sweep trace.Because former sweep trace is very long, so scanning plane is also very big, enough can cover the inaccessiable zone of heap taking equipment, solved the problem of fixed measurement blind area in making an inventory automatically.
The beginning of making an inventory; The heap in stock ground is got before material equipment moves from start bit, drives the two dimensional laser scanning appearance by the gauge head whirligig and begins rotation sweep, because the scanning area area is big; Pile the zone that taking equipment can not pass through before having covered start bit, so this zone also is measured to; After the start bit blind area measure accomplished, getting advancing or rotating of material equipment through heap, scanner carries out continuous profile scanning and calculates the material stack volume that has scanned simultaneously stockpile; When the heap taking equipment moves to terminal point; Because some zone heap taking equipment of back can not be pass by; Drive two dimension calculating scanner through the gauge head whirligig again and be rotated scanning, can cover this regional scanning survey, whole process does not exist measures the blind area.The two dimensional laser scanning appearance is given computer service system with data upload in real time through EPA.
In the inventory procedure, main control unit is gathered the travel distance or the anglec of rotation that the anglec of rotation of gauge head whirligig and heap that the stroke measurment unit measures are got material equipment in real time through the RS485 communication modes, and is uploaded to computer service system through EPA.
In the inventory procedure; If the pitching action is arranged on the windrow arm that the two dimensional laser scanning appearance is installed in; Main control unit is gathered in real time through the RS485 communication modes and is installed in the obliquity sensor data on the windrow arm, detects the variation of luffing angle, has guaranteed the accuracy of measuring.
