(2) collection stick into lock, by optical recognition devices determine the homework type of truck for putting case or suitcase, And gather truck data, determine operation field bridge and working region thereof, and judge truck problem:

In this example, the container number that truck Tianjin HB224 loads is TPCU123567, box size 40 chi, Carry out putting casing working, through photoelectricity identification equipment, container number, box identified automatically after entering sluice gate 1, Confirming as putting casing working, with the static images that photographic head picked-up five sides of container are complete, driver brushes RFID Card, reads the rfid card data of truck with the POS, and by Card Reader, central control unit carries out collecting card According to number, truck deadweight, name of vessel flight number, case number (CN), box size, ice chest mark, danger product mark, bare weight The collection of mark；Pit scale weighs truck gross weight.First Validation of Data, checking reality are carried out Case number (CN) is consistent with case number (CN) in rfid card, it is overweight not have, and central control unit is through being analyzed point gathering data Join this truck to march into the arena district A0150 shellfish position, target field Wei Shi branch.Damaged by manually carrying out to the image gathered Identification, confirmed without damaged.

As it is shown on figure 3, be that the operation field bridge 4 putting case truck is in its working region of container pier storage yard Position view.In the present embodiment, arrange field bridge 4 at branch district A01 according to field bridge Job partition plan Carrying out land transportation operation with A02 Liang Ge branch district, the GPS of current field bridge 4 is positioned at the 03 of branch district A01 Shellfish position and branch district A01 and A02 do not have any operation, relief area 3 do not enter into yet branch district A01 and A02 truck job instruction；

(2.2) acquired data analysis confirms that actual case number (CN) is consistent with case number (CN) in rfid card, it is overweight not have, figure After determining that truck is out of question as identification, proceed to step (3)；

(3) judge that relief area truck is the most saturated according to the truck sum in relief area, if saturated, close Closing sluice gate, if unsaturated, proceed to step (4), relief area degree of crowding BP decision rule is as follows:

Wherein, m is relief area truck sum, and M1, M2, M3 are relief area degree of crowding parameter, unit For " "；In this example: relief area truck number m=10, M1=0；M2=100；M3=200

Judge: current buffer truck number is 10, and 0 ＜ 10 ＜ 100, therefore relief area is in the free time State, normal operation；

(4) judge that the truck of same working region A01 and A02 has been entered in relief area；

(4.1) if having entered same working region truck, this truck proceeds to buffer queue scheduling, and through wheel Asking T1 interval time and proceed to step (4.2), poll-interval T1 is set to 30 seconds；Namely buffering row In team's scheduling process, often through 30 seconds interval times, the working region in stockyard of central control unit inquiry A bridge whether is had in A01 and A02；

(4.2) because of in this example relief area do not enter the truck of same working region (branch district A01 and A020), Judge whether there is a bridge, in the present embodiment, according to field bridge in described working region A01 and A02 further Job partition plan arrangement field bridge 4 carries out land transportation operation, at present in two places of branch district A01 and A02 The GPS of this bridge is positioned at the 03 shellfish position of branch district A01, and branch district A01 and A02 does not has any work Industry, it is determined that conclusion: have a bridge.

(5) if there being a bridge, judging state evaluating method by described field bridge busy, converting this bridge mark Quasi-job instruction number, and then judge field bridge busy-idle condition, concrete operation is as follows:

(5a) field bridge standard operation instruction number conversion:

The target field position of this truck distribution is A01 place 50 shellfish, and for putting casing working,

(5a1) first convert total used time:

$T\left(n\right)=r\&times;\mathrm{QOT}+z\&times;\mathrm{QTT}+\left(\underset{n=1}{\overset{n}{\mathrm{\&Sigma;}}}n(\mathrm{\&beta;}+1)\right)\&times;\mathrm{QOE}+\underset{x=1}{\overset{n}{\mathrm{\&Sigma;}}}\mathrm{MT}\left(x\right)$

In above formula:

N: existing job instruction number；

β: the coefficient of falling case；

QOT=field bridge spends field time, unit second；

QTT=field bridge transition times, the unit second；

QOE=field bridge completes the standard duration needed for a standard operation instruction, in this example:

QOE=80 second/standard operation instruction；

MT (x)=field bridge is put, to next, the target field position that casing working specifies by current field displacement and is taken Between, the unit second；

Concrete operation result:

Analyze: r=go through the motions number of times, z=transition number of times, owing to field bridge current position and target field position are together One branch district A01, so r and z value is all 0

Homework type is for putting casing working, so β=0,

The computation rule of MT (x) is:

$\mathrm{MT}\left(x\right)=\left\{\begin{array}{cc}A\&times;\mathrm{QLS}+B\&times;\mathrm{QMS}+(L\left(x\right)-2A-2B)\&times;\mathrm{QFS}+B\&times;\mathrm{QMS}+A\&times;\mathrm{QLS}& 2A+2B<L\left(x\right)\&le;\mathrm{MB}\\ A\&times;\mathrm{QLS}+(L\left(x\right)-2A)\&times;\mathrm{QMS}+A\&times;\mathrm{QLS}& 2A<L\left(x\right)\&le;2A+2B\\ L\left(x\right)\&times;\mathrm{QLS}& 0<L\left(x\right)\&le;2A\end{array}\right.$

Wherein,

QLS=machinery low speed=15 second/shellfish

QMS=machinery middling speed=10 second/shellfish

QFS=machinery full speed=5 seconds/shellfish

In A=, low speed boundary shellfish is away from=1 shellfish

B=high speed boundary shellfish is away from=3 shellfishes

MB=stockyard Bulbus Fritillariae Thunbergii number is away from=100 shellfishes

L (x)=field bridge is put, to next, the target field position that casing working is specified by current field displacement Distance, unit is shellfish；

T (n)=field bridge moves to perform the target field position of the n-th job instruction from present position The required time, n=1 in the present embodiment.

Now L (x)=50 (location of instruction)-03 (Chang Qiao current location)=47 shellfishes,

2+6 < L (x) < 100, so,

Work as X=1

MT (x)=1 × 15+3 × 10+ (47-2-6) × 5+3 × 10+1 × 15=285 second

∑ MT (x)=285 second

Draw: T (n)=0+0+80+285=365 second

(5a2) Jiang Changqiao moves to target field position required time and is converted to standard operation instruction number

$I\left(n\right)=\frac{T\left(n\right)}{\mathrm{QOE}}$

I (n)=365/80=4.56 ≈ 5

(5b) assessment field bridge busy-idle condition

According to above-mentioned steps 2) the field bridge that is converted into moves to the standard required for target field position from present position Job instruction number I determines the busy-idle condition P of a bridge:

The busy-idle condition P of field bridge is divided into 3 grades, it is stipulated that as follows:

Wherein, N1, N2, N3 are the busy extent index of a bridge, and unit is " standard operation instruction "； N1=0；N2=3；N3=20；

Judged result: field bridge 4 completes this job instruction and is time-consumingly converted to standard operation instruction number is 5, 3 < 5 < 20, illustrate that field bridge 4 is in busy state, judge that truck Tianjin HB224 is not from buffering further The truck in district, from sluice gate, takes T2 time delay to lift banister pin, and time delay, T2 was set to 40 Second.Judged result is state of can marching into the arena, and at this moment job instruction transmits, by field bridge display terminal, bridge 4 of showing up, Field bridge terminals shows puts casing working instruction, truck license plate numbers, time of marching into the arena, container number, box chi Very little, homework type (putting case, suitcase) and target field position, driver shifts after receiving job instruction. After 40 seconds, sluice gate receipt printing machine printing field bridge 4 enters the job ticket in stockyard.Driver gets job ticket charge operation.

Embodiment 2

Truck performs pick-up operation and enters the dispatching method of lock.Described dispatching method is characterised by including as follows Step:

(1) formulate field bridge Job partition plan and set conventional parameter with embodiment 1.Current buffer 3 In truck be 15；

(2) collection sticks into lock, sees Fig. 2, Fig. 3；

Truck Tianjin HA111, suitcase number is TPCU2222222, and box size 20 chi carries out pick-up operation, Automatically identify without container through photoelectricity identification equipment after entering sluice gate 1, it is judged that it is pick-up operation, driver Brush rfid card, reads rfid card by the POS, and central control unit carries out truck license plate numbers, truck The collection of deadweight.Driver is by the reservation bar code on bar code scanner scanning suitcase list, it is thus achieved that suitcase Case number (CN) and to the sluice gate time, and then determine position, suitcase field, position, suitcase field in A02 place, 99 shellfish positions.First First carrying out problem checking, problem includes fault of swiping the card, i.e. card damage cannot be swiped the card, or truck arrives the most on time Sluice gate.

Fig. 3 illustrates the field bridge 4 carrying out pick-up operation position in its working region of container pier storage yard 1 Put schematic diagram.Arrange field bridge 4 in two places of branch district A01 and A02 according to field bridge Job partition plan Carrying out land transportation operation, current field bridge 4 is carrying out the casing working of putting of embodiment 1 and instructs, and then performs basis Pick-up operation in embodiment instructs, and branch district A01 and A02 does not has any operation, and relief area 3 is also Do not enter into branch district A01 and A02 truck job instruction.

Confirming through central control unit, there is not Card Reader fault and shows by reservation bar code in truck Tianjin HA111 The subscription time gone out arrives sluice gate, therefore, it is determined that truck is out of question.

3) judge that relief area truck is the most saturated according to the truck sum in relief area, if saturated, close Sluice gate, if unsaturated, proceeds to step (4), and relief area degree of crowding BP decision rule is as follows:

Wherein, m=15, M1=0；M2=100；M3=200

Judge: current buffer truck number is 15, and 0 ＜ 15 ＜ 100 therefore relief area is in idle condition, Normal operation.

(4) judge that the truck of same working region A01 and A02 has been entered in relief area；

(4.1) if having entered same working region truck, this truck proceeds to buffer queue scheduling, and through wheel Ask T1 interval time and proceed to step (4.2)；Poll-interval T1 is set to 30 seconds；Namely buffering row In team's scheduling process, often through 30 seconds interval times, the working region in stockyard of central control unit inquiry A bridge whether is had in A01 and A02.

(4.2) because of in this example relief area do not enter same working region truck, proceed to step (5)；

(5) judge whether there is a bridge, in the present embodiment, according to field in described working region A01 and A02 Bridge Job partition plan arrangement field bridge 4 carries out land transportation operation, mesh in two places of branch district A01 and A02 Before this bridge be carrying out in embodiment 1 put casing working instruction and branch district A01 and A02 the most any Operation, relief area 3 does not enters into branch district A01 and A02 truck job instruction yet, it is determined that conclusion: have Field bridge.

(5.2) if there being a bridge, judging state evaluating method by described field bridge busy, converting this bridge mark Quasi-job instruction number, and then judge field bridge busy-idle condition, concrete operation is as follows:

(5a) field bridge standard operation instruction number conversion:

This truck target field position is 99 shellfishes of place A02, and is pick-up operation,

(5a1) first convert total used time:

$T\left(n\right)=r\&times;\mathrm{QOT}+z\&times;\mathrm{QTT}+\left(\underset{n=1}{\overset{n}{\mathrm{\&Sigma;}}}n(\mathrm{\&beta;}+1)\right)\&times;\mathrm{QOE}+\underset{x=1}{\overset{n}{\mathrm{\&Sigma;}}}\mathrm{MT}\left(x\right)$

In above formula:

N: existing job instruction number；

β: the coefficient of falling case；

QOT=field bridge spends field time, unit second；

QTT=field bridge transition times, the unit second；

QOE=field bridge completes the standard duration needed for a standard operation instruction, in this example:

QOE=80 second/standard operation instruction；

Needed for the target field position that MT (x)=field bridge is specified by current field displacement to next pick-up operation Between, the unit second；

Concrete operation result:

Analyze: A01 to A02 is longitudinal transition, and transition is once, so r=0, z=1

Homework type is pick-up operation, β=0.5, QOE=80 second/standard operation instruction；

The computation rule of MT (x) is:

$\mathrm{MT}\left(x\right)=\left\{\begin{array}{cc}A\&times;\mathrm{QLS}+B\&times;\mathrm{QMS}+(L\left(x\right)-2A-2B)\&times;\mathrm{QFS}+B\&times;\mathrm{QMS}+A\&times;\mathrm{QLS}& 2A+2B<L\left(x\right)\&le;\mathrm{MB}\\ A\&times;\mathrm{QLS}+(L\left(x\right)-2A)\&times;\mathrm{QMS}+A\&times;\mathrm{QLS}& 2A<L\left(x\right)\&le;2A+2B\\ L\left(x\right)\&times;\mathrm{QLS}& 0<L\left(x\right)\&le;2A\end{array}\right.$

Wherein,

QLS=machinery low speed=15 second/shellfish

QMS=machinery middling speed=10 second/shellfish

QFS=machinery full speed=5 seconds/shellfish

In A=, low speed boundary shellfish is away from=1 shellfish

B=high speed boundary shellfish is away from=3 shellfishes

MB=stockyard Bulbus Fritillariae Thunbergii number is away from=100 shellfishes

The target field position that L (x)=field bridge is specified by current field displacement to next pick-up operation Distance, unit is shellfish；

T (n)=field bridge moves to perform the target field of the n-th job instruction from present position Time required for Wei, n=2 in the present embodiment.

Judge: now L (x)=100 (the Bulbus Fritillariae Thunbergii number in single game district away from)-50 (upper operations The location of instruction)=50 shellfishes, 2+6 < L (x) < 100, so

When x=1 (embodiment 1 puts casing working instruction)

MT (x)=1 × 15+3 × 10+ (47-2-6) × 5+3 × 10+1 × 15=285 second

When x=2 (instruction of the present embodiment pick-up operation)

MT (x)=1 × 15+3 × 10+ (50-2-6) × 5+3 × 10+1 × 15=300 second

∑ MT (x)=285+300=585 second

Draw: T (n)=0+800+ (80+1.5 × 80)+585=1585 second

(5a2) field bridge is converted to instruction number to target field position required time

$I\left(n\right)=\frac{T\left(n\right)}{\mathrm{QOE}}$

Bridge 4 completes the standard operation instruction number that casing working elapsed time is converted into of putting of this truck:

I (n)=1585/80=19.81 ≈ 20

(5b) assessment field bridge busy-idle condition

According to step 2) the field bridge that calculates moves to the standard required for target field position from present position and makees Industry instruction number I determines the busy-idle condition P of a bridge:

The busy-idle condition P of field bridge is divided into 3 grades, it is stipulated that as follows:

Wherein, N1, N2, N3 are the busy extent index of a bridge, and unit is " standard operation instruction "； N1=0；N2=3；N3=20

If (5.2.1) field bridge is in saturation, then this truck proceeds to buffer queue scheduling；

Judged result: field bridge 4 performs this job instruction and is converted to standard operation instruction number is 20,20=20, Field bridge is in saturation, enters relief area waiting, time zone display screen display license plate numbers Tianjin HA111, handles Mode is self-service handling, and driver only needs to wait for, with automatic regular polling, buffer scheduling waits that working region, stockyard is No have a bridge, during until field bridge 4 instruction number is less than 20, enters busy state, judges that truck is further From the truck of relief area, being entered stockyard by relief area immediately, relief area goes out district's display screen display set card According to number Tianjin HA111, mode is print job list, and is limited to 15 points when providing printing, as exceeded this time limit, It is last that collection snaps into queue queue.At this moment driver is made by relief area receipt printing machine self-help print admission in relief area Industry list, the pick-up operation instruction of field bridge terminals display simultaneously, truck license plate numbers, time of marching into the arena, container Number, box size, homework type (putting case, suitcase) and target field position, field bridge driver operates.
