And when the turning triggering instruction is received, executing the turning automatic position selection allocation strategy (namely the turning automatic position selection allocation method for the container in the container area) of the container area.
As shown in fig. 4, when a box needs to be turned over in the box area operation, the system automatically triggers a box turning task, calls the box turning position selection decision of this embodiment to perform box turning position selection, and performs operation according to the result of the box turning position selection.
In this embodiment, the position of the container area where the container to be turned over is located is first obtained, and then the position selection range of the position is determined according to the position of the container area where the container to be turned over is located.
Specifically, in this embodiment, the determining the position selection range according to the position of the container area where the container to be turned over is located specifically includes:
acquiring the box area type of the container to be turned over currently, and determining the position selection range of the shellfish position according to the box area type:
and if the container to be turned over is a two-end type container area, determining a shell position range formed after the current shell position is increased by a first preset number of shell positions before and after the current shell position is taken as a shell position selection range by taking the current shell position where the container to be turned over is located as a center.
Wherein the first preset number is but not limited to 1 to 10; preferably 10.
That is, in this embodiment, for the two-end box area: the method comprises the steps of determining the range of front and back 10 shellfish bits as a shellfish bit selection range by taking the current shellfish bit as a center, and searching whether an optional position exists or not by using the range of front and back 10 shellfish bits of the current shellfish bit.
And if the container to be turned over is the cantilever type container area, determining the current position of the container to be turned over as the position selecting range of the position.
That is, in this embodiment, the optional position is found in the current shellfish position for the cantilever box area.
Particularly, in this embodiment, when a no-selectable-position signal that the position selection position of the container to be turned over cannot be determined is received, increasing and expanding a second preset number of shellfishes before and after the position selection range of the shellfishes, updating the position selection range of the shellfishes, and performing position selection again on the container to be turned over according to the updated position selection range of the shellfishes.

The container attribute in the present embodiment will be specifically described below.
1) The box state is as follows: containers have different states depending on different transportation routes and destinations. Judging conditions: and judging according to whether the box states are the same.
A distinction is made between export/import/ship/barge. The inlet box is unloaded from the ship and is subsequently transported by the truck-collecting lifting box at the direction of the road junction; the exit box is a container which enters a storage yard from a road junction and is transported by a ship in the future; large ships are generally going out of the sea; the barge is a river with much transportation in the Yangtze river and a boat with much transportation in the Yangtze river. In addition, empty boxes and non-empty boxes are also distinguished. The method comprises the following specific steps:
OF: heavy case of export, direction of transportation: the collection card- > box area- > ship/barge;
OE: export empty box, direction of transportation: the collection card- > box area- > ship/barge;
OZ: export transfer, transport direction: generally, a ship transfers to a barge, wherein the ship- > box area- > barge;
IZ: import transfer, direction of transportation: generally, a barge is transferred from a large ship, and the barge is also transferred to the barge, wherein the large ship is larger than a box area and larger than the barge or the barge is larger than the box area and larger than the barge;
t: international transit, direction of transportation: a large ship- > a storage yard- > a large ship;
TE: an international transfer empty box;
IF: heavy case of import, direction of transportation: a large ship/barge- > a box area- > a card collection;
IE: import empty case, direction of transportation: a large ship/barge- > a box area- > a card collection;
RF: and (4) discharging and turning over the bin box, and arranging the position of the current container on the ship by means of a storage yard. The transportation direction is as follows: a large ship- > a box area- > the same large ship;
RE: taking out the empty box of the turning bin;
CF: a clearance box, which does not close the containers needing to be kept in the yard;
a refrigerating box: a container with a temperature tag;
hazardous articles: containers with hazardous material categories.
2) Case height (CHEIGHT CD)
Judging conditions: a high box and a flat box.
Generally divided into high-box (HQ) and flat-box (PQ). For example, in a typical automated container terminal, stacking 6 levels typically requires a total height of no more than 2 high and 4 flat.
3) Case type (CType)
Judging conditions:
GP: common box
OT: the top box is opened, and the stacking method can be equivalent to a common box.
FR: frame boxes, typically requiring individual stacking
RF: refrigerating box
4) Port of destination (UnldPort)
Judging conditions: whether the destination ports are the same.
For export/transfer boxes there will generally be the "next port" attribute, i.e. which port the container will be unloaded in the future. This parameter is often required to be determined in the stacking condition. For example, CNSHA indicates that the destination port is Shanghai.
5) Weight (Weight)
Judging conditions: whether the box is empty or not, whether the box is light or not and pressing the box on a heavy box or not and the like;
the non-empty boxes generally have weights and need to be classified according to the weights, and the boxes are stacked according to the weight grades after the weight grades are obtained.
6) Person holding case (CoperCD)
Judging conditions: whether the person holding the box is the same.
For empty boxes, the same box holder carries/enters boxes in batches often, so that the empty boxes need to be stacked according to the box holder.
7) Bill number (Bill No)
Judging conditions: whether the bill of lading numbers are the same.
The heavy imported containers are stacked according to the bill of lading, and the probability that the containers with the same bill of lading are lifted away simultaneously is higher.
8) Export voyage (Evoy)
Judging conditions: whether the exit voyage is the same.
3. The same representative will be loaded onto the same vessel.
9) Import voyage (Ivoy)

In this embodiment, the method for automatically selecting and allocating the container turning over positions of the container in the container area further includes: and if a plurality of optional positions meeting the conditions are obtained from the feasible optional positions, selecting any optional position as the position selection position of the container to be selected.
That is, a plurality of optimal results may be obtained according to the position selection judgment condition of the container attribute and the preset position selection judgment condition, and then any one of the plurality of optimal results is selected as the position selection position. Different bit selection strategies are used according to different types of containers.
As can be seen from the above, the automatic position selecting and allocating method for container turning in a container area of this embodiment is mainly divided into three parts, the first part is to call by using distance first (determining a position selecting range of a shellfish position according to the shellfish position of the container area where the container to be turned is located), the second part is to perform feasibility judgment (performing feasibility judgment on an optional position within the position selecting range of the shellfish position according to feasibility judgment conditions), and the third part is to perform optimized pruning (judging an obtained feasible optional position according to position selecting judgment conditions of container attributes and preset position selecting judgment conditions). Through the three parts, a better solution of the box turning and position selecting can be obtained under the condition of effectively limiting the position of the position selecting.
Fig. 5 is a flow chart of the implementation process of the container turning automatic position selection allocation method for the container area containers.
Starting from a calling stage, firstly preprocessing data when a box turning triggering instruction is received, then determining an initial range for selecting bits (namely a bit selecting range) according to the step of the bit selecting range of the shell bits, and then carrying out optimization decision after judging feasibility (namely judging the feasible selectable positions according to the bit selecting judgment condition of the container attribute and a preset bit selecting judgment condition). If the result (the bit-selection position) is obtained, returning the decision result; and if no result exists, expanding the selection range, then continuing to select the bit, and returning to the flow of feasibility judgment.
For example, for a two-ended box: and searching whether an optional position exists or not according to feasibility judgment conditions, position selection judgment conditions of container attributes and preset position selection judgment conditions by taking the positions as the center and the range of front and rear 10 positions.
