The application scenarios that the present invention is applied to electronic chart is below described.
Basic definition is at first described.
1, conflict
Conflict refers to two different tasks, may produce the editor for same key element, and produces contradiction.
2, map edit
Map edit is the attended operations such as the increase of finishing map elements, modification, deletion.
3, task definition and assignment
Task definition is the definition of carrying out the map edit task, describes editor's data area; During task assignment with the definition task assignment to the editor, the beginning map editor.
4, the map edit key element collection of task
The map edit key element of task refers to the set of the map elements that a task may be edited.
The line description of advancing by leaps and bounds below liquidates.
If the editorial elements set that the task of a definition is possible is ES_TID, wherein TID is corresponding mission number.
ES_TID={<ET, EID 〉, wherein ET is the key element type, EID is the permanent ID of key element.
Suppose to have two task t1 and t2, but the set of corresponding editorial elements is for ES_t1 and ES_t2, if but two editorial elements intersection of sets collection non-NULLs illustrate this two task potentially conflictings so.
If the set of tasks of the conflict that the task of a definition is possible is TCS_TID, wherein TID is corresponding mission number.
TCS_TID={TID}, wherein TID is mission number, and belongs to movable.
Suppose to have 1 task t1, if corresponding potentially conflicting set TCS_t1 is empty, t1 is can carrying out immediately of task so.
As shown in Figure 4, the conflict prevention apparatus function structure of map edit task definition and assignment is as follows in the application scenarios of the present invention:
(1) task definition module (being similar to above-mentioned acquiring unit)
The definition of finishing the work mainly comprises title, type, scope of work, planned time, editor of task etc.
(2) but editorial elements set computing module (being similar to the subelement that obtains in the first above-mentioned judging unit)
Based on the scope of work of task, the key element that calculating may be edited.
(3) possible conflict set adds up to calculation module (being similar to the second judgment sub-unit in the first above-mentioned judging unit)
Calculate the Conflict Tasks possible with defined task.
(4) processing module (being similar to above-mentioned processing unit) is intervened in conflict
For possible conflict, according to the decision-making that the supvr takes, carry out respective handling.
(5) task finishes feedback module
After the task processing finished, other tasks that see if there is this task of dependence did not also begin to carry out, and provide corresponding prompting or activation.

But the calculating of the editorial elements of task set depends on the defined scope of work of this task.The scope of work of a task can be:
(1) but the editing area by spatial dimension definition.
(2) the editable key element type by the key element type definition.
(3) by specifying the editable key element of concrete key element definition.
But when calculating editorial elements based on scope of work, consider the characteristic of map: (1) topological relation.(2) logical relation.
The below is the explanation that editing area carries out process with scope of work, and described method comprises:
(1) according to the defined editing area of task t, chooses the key element that is positioned at this editing area;
(2) but selected key element is added editorial elements set ES_t;
(3) but based on editorial elements, judge whether to have topological relation or logical relation with the outer key element of editing area;
(4) but will exist the key element of topological relation and logical relation also to add editorial elements set ES_t.
Below describe possible conflict set and add up to the principle of work of calculating module, comprising:
(1) judges whether the task of existence activity, if do not have, finish;
(2) if movable task is arranged, but judge the editorial elements set ES_t of current defined task t, with the task t ' of activity but editorial elements set TS_t ' whether be empty; If non-NULL, the active task t ' with correspondence adds TCS_t so.
Below describe the principle of work that processing module is intervened in conflict, comprising:
(1) if the TCS_t non-NULL of current task t, whether there is possible conflict in prompting user so, and is determined the action taked by the user, namely execute the task.
(2) user can select to force to assign to carry out, and can wait for that also the task of its conflict is finished.
(3) after selecting wait, the task status of correspondence is set to wait for.
Below describe the principle of work that task finishes feedback module, comprising:
(1) after tasks carrying is finished, the task of judging whether wait waits for that again it finishes, if do not finish;
(2) if having its numbering of deletion among the set TCS_t of its task of wait;
(3) if corresponding set TCS_t is empty after the deletion, to remind so corresponding task t can begin to carry out.
The invention provides a kind of conflict prevention method of map edit task assignment, in task definition and assignment, just pre-anti-collision, can carry out conflict prevention in conjunction with whole at present task status, to avoid defining the task that may lead to a conflict, application demand can be satisfied like this, the solution expense of conflict can be reduced again.The present invention can judge possible conflict, and remind after conflict is removed.
By above scheme, reach following effect:
(1) when formulating task, can carry out whether having the judgement of potentially conflicting with ongoing task, and then remind the supvr to adjust the scope of task, to avoid a conflict.
(2) supvr can to make a strategic decision be that initiating task is carried out, after the task of still waiting for potentially conflicting finishes, restart the execution of the task that defines.
(3) after tasks carrying is finished, can judge whether to have to occur and waiting in order to avoid a conflict of task, if there is such task, can remind the supvr to start the execution of these tasks.
The above is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
