A kind of halved belt sorts means for correcting and its bearing calibration of trolley cargo
Technical field
The present invention relates to a kind of means for correctings, and in particular to a kind of halved belt sorts means for correcting and its school of trolley cargo
Correction method.
Background technology
With the fast development of Chinese economy, modern logistics industry also enters rapid growth period.Material flows automation is as existing
For the important component of logistics, the developing direction of entire logistic industry decide.Halved belt Automated Sorting System is due to automatic
Many advantages, such as change degree is high, sorting efficiency is high, is entirely occupying an important position in material flows automation field.
Sort core apparatus of the trolley as carbel sorting, be responsible for cargo correctly, be quickly transported to purpose
Website, his integrity, accuracy play conclusive effect to the performance of entire carbel sorting.It is most at present
Carbel sorting in cargo to be transported to sorting trolley from piece uploading controlled by program, when face it is larger or
When smaller cargo, it can not sufficiently accurately be sent to the center of sorting trolley.Also less a part of high-end intersection
Band sorting system carries out position control in piece uploading device using light curtain, and this form is merely able to relatively good guarantee piece uploading
The accuracy of program, it is impossible to ensure that parcels and goods move to the specific location on sorting trolley in sorting system actual motion.
Parcels and goods in the position of sorting trolley if not going out in central area, in the fast website close to sorting, due to
Crab traversing speed quickly, different sorting website it is adjacent to each other etc., trolley largely can will under the control of pre-booking process
Cargo is sent to targeted sites are previous or the latter website, and error rate is caused to increase.Due to entire sorting system trolley quantity
Numerous, daily sorting amount is ten hundreds of or even hundreds thousand of, therefore the amount of dislocation cargo caused by this error rate can be very big, meeting
Huge loss is caused to logistic industry.

Length.
The present invention at work, is sorted cargo and passes sequentially through waiting section 5, accelerating sections 4 and sync section in piece uploading device 6
3 cooperation is sent on sorting trolley 2, and sorting trolley 2 is moved along circular orbit 1, when sorting trolley 2 close to measure and control device 7,
It sorts the trolley in trolley 2 and communicates 23 groups of transmission communication instructions of communication group 7403 into nucleus module 74.
When nucleus module 74, which does not return to determination, receives instruction, the trolley communication group 23 in trolley 2 is sorted again to core
Communication group 7403 in module 74 sends communication instruction.
Receive instruction when nucleus module 74 returns to determination, that is, it is infrared in nucleus module 74 after being properly received communication instruction
Ranging group 7404 start, and measure sorting trolley 2 in trolley communication group 23 to the communication group 7403 in nucleus module 74 away from
From, and the floor projection for sorting 2 center of trolley to 73 center of high speed camera module is calculated apart from (computational methods are to be divided
After picking the trolley communication group 23 to the distance of the communication group 7403 in nucleus module 74 in trolley 2, due to small in sorting trolley 2
The vertical range between communication group 7403 in vehicle communication group 23 and nucleus module 74 is fixed value, can be obtained by trigonometric function
The projection of distance in the horizontal plane to the trolley communication group 23 in sorting trolley 2 to the communication group 7403 in nucleus module 74 is grown
Degree arrives the distance between high speed camera module 73 in horizontal plane further according to the communication group 7403 of precalculated nucleus module 74
On projected length, can both obtain sorting 2 center of trolley to 73 center of high speed camera module floor projection distance).Root again
According to the current real-time sorting speed that the velocity measurement sensor 24 in sorting trolley 2 measures, sorting trolley 2 can be calculated and reached
The time t1 of 7 central plane of measure and control device (i.e. measuring control point).Timer 7401 in nucleus module 74 is started to work, initial value
T=t1+t2;
Wherein t2 is the time that high speed camera module 73 starts.
When the timer is zeroed, high speed camera module 73 works, and claps the photo for taking sorting trolley 2 and bulk-breaking cargo 8.It claps
According to rear, the image processor 7405 in nucleus module 74 carries out binary conversion treatment to the photo, then extracts bulk-breaking cargo
Profile calculates the coordinate value of the central point of 8 profile of bulk-breaking cargo.Logic processor 7402 in nucleus module 74 is by the coordinate
Value is compared with image center coordinate, and finds out deviation, is judged again deviation later, if in normal range (NR)
It is interior, if it is not, then recalculating, if so, the deviation is sent to by the communication group 7403 in nucleus module 74
In trolley communication group 23 in corresponding sorting trolley 2 far from measure and control device 7.Trolley communication group 23 in sorting trolley 2 exists
It is properly received after changing deviation, which is converted to motor control instruction by the control processor 25 sorted on trolley 2, and is controlled
Motor 20 processed starts, while also belt 21 being driven to rotate, and bulk-breaking cargo 8 is adjusted to the center of sorting trolley 2, realization point
The correction of part cargo 8.
