detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

An embodiment of the present invention provides a smart home system, which applies a timing task conflict resolution device and a timing task conflict resolution method. When a user adds a new timing task, the new timing task and the existing timing task can be detected according to the timing task conflict detection mechanism. Whether there is a conflict between tasks, and can avoid the occurrence of timed task conflicts in the smart home system, and improve the stability of the smart home system.

It should be understood that the above-mentioned timed task conflicts should be understood as one or more users setting two or more different actions on the same device within the overlapping time period, and there is a possibility between the two or more actions conflicted. For example, user A sets a timed task "open the windows of the living room every day between 7:30 and 8:30 am", and user B sets a timed task "close the windows of the living room at 8 am every day". Since the execution time periods of the timed tasks set by user A and user B overlap, and during the overlapping time period, the windows in the living room need to perform two completely opposite actions, so that the windows are in a state of conflict, so it is considered The scheduled task set by user A conflicts with the scheduled task set by user B.

Referring to Fig. 1 , the timed task conflict resolution device 100 includes a task receiving module 10, a conflict detection module 30 and a task execution module 50, the task receiving module 10 is used to receive a new timed task added by a user, and the conflict detection module 30 is used to detect whether there is a conflict between the execution time of the new timed task and the execution time of the existing timed task in the smart home system, and to determine the priority of the new timed task and the existing timed task, The execution module 50 is used to control the devices of the smart home system to execute the tasks with higher priority detected by the conflict detection module 30 .

Specifically, in this embodiment, in order to complete the conflict detection when the timed task is added, the conflict detection module 30 applies a timed task conflict detection mechanism based on a rule model, specifically a dynamic detection mechanism for timed task conflicts. It should be understood that the above-mentioned rule model expresses the entities involved in the scheduled tasks in the form of models, and the specific scheduled tasks are expressed in the rules between the models. In this embodiment, the entities mainly involved in the timing task include but are not limited to: user entities, equipment entities, and timer entities. The task rules should be understood as: user entities set time or/and time periods to The trigger device entity is in a specific state, so that any timing task can be realized through the definition of a formal rule model. The timing task rule model is Timer_Task1={User1, Device1, Timer1}, Timer_Task2={User2, Device2, Timer2} and Timer1∧Timer2≠0.

Please refer to FIG. 2 at the same time. FIG. 2 shows a schematic diagram of steps of a timing task conflict detection mechanism provided by an embodiment of the present invention. The timing task conflict detection mechanism includes a conflict detection phase and a conflict avoidance phase. specifically:

After the conflict detection module 30 detects that a new timing task is added, the step of carrying out conflict detection comprises steps:

Step S101: task classification; specifically, the conflict detection module 30 classifies tasks according to the type of the new scheduled task;

Step S103: task linkage setting; specifically, the conflict detection module 30 determines one or more equipment entities required to execute the new timed task, and sets connections between multiple equipment entities; at this time, the conflict When the detection module 30 performs task linkage setting, it needs to analyze in conjunction with the existing scheduled tasks in the system. In other words, the scheduled task rule library of the system stores the task rules of the existing scheduled tasks. There are scheduled task rules for comparison and integration to establish a linkage relationship between tasks;

Please refer to FIG. 3, specifically, in the above step S103, after the timed task conflict resolution device 100 receives the added new timed task, the conflict detection module 30 compares the new timed task with the existing timed task Compare the task rules in the rule base and perform conflict detection, including the following sub-steps:

Step S1031: Determine whether the device identification numbers of the new scheduled task and the existing scheduled task are the same, if they are the same, execute step S1033; if not, consider that there is no conflict between the new scheduled task and the existing scheduled task, and the new scheduled task passes Conflict detection, execute step S1037;

Step S1033: Determine whether the task execution time of the new scheduled task and the existing scheduled task overlap, if they overlap, execute step S1035; if not, it is considered that there is no conflict between the new scheduled task and the existing scheduled task, and the new scheduled task passes Conflict detection, execute step S1037;

In step S1033, the conflict detection module 30 needs to judge whether there is a conflict between the new scheduled task and the existing scheduled task according to the execution time period or time point of the new scheduled task and the existing scheduled task. In this embodiment, conflict detection between a time segment and a time point is performed by judging whether the time point is included in the interval of the time segment. If the time point falls within the interval of the time segment, it is considered that there is a conflict between the time segment and the time point, and the execution time of the two tasks conflicts. On the contrary, it is considered that there is no time conflict between the time period and the time point. By analogy, if it is necessary to determine whether there is a conflict between time periods, it can be obtained by comparing the start and end time points of one time period with the other time period.

Specifically, please refer to FIG. 4 at the same time. FIG. 4 schematically shows several types of task execution time conflicts: the task execution time of an existing scheduled task to be matched and detected in the scheduled task rule base is represented by a time segment template, where , the time point T1 indicates the start time of the existing scheduled task, and the time point T2 indicates the end time of the existing scheduled task. The task time of the new scheduled task is represented by time point sample A and time period samples A~F.

In this embodiment, the conflict detection module 30 judges: when any one of the start time point or the end time point of the template time period and the sample time period conflicts, the two time periods conflict; When there is no conflict between the start time point and the end time point of the time period, there is no conflict between the two time periods. There is a special case: the start time point of the sample time period is before the start time point of the template time period, and the time period of the sample time period The end time point is after the end time point of the template time period. Although there is no conflict between the start time point and the end time point of the template time period and the sample time period, the template time period is included in the sample time period, so two Time slots conflicted. In short, two time periods are considered to be in conflict when there is an intersection between the interval of the template time period and the interval of the sample time period. According to the law of conflict between the above two time periods, the embodiment of the present invention also provides a time conflict algorithm based on the regular task rule library:

Step S1035: Determine whether the user rights for adding a new scheduled task are the same as those for adding an existing scheduled task. If they are the same, it will be considered that there is a conflict between the new scheduled task and the existing scheduled task, and step S1039 will be executed; if they do not overlap, it will be considered that the new scheduled task There is no conflict between the task and the existing scheduled task, the new scheduled task passes the conflict detection, and step S1037 is executed;

Step S1037: Add the new scheduled task to the regular task rule library; the program ends;

Step S1039: Judging that the new scheduled task has conflicted with the existing scheduled task, prompting the user to modify the scheduled task, when the user modifies the scheduled task, it is deemed that the user has added a new scheduled task, and the conflict detection module 30 repeats step S1031 until the new scheduled task There is no conflict between the scheduled task and the existing scheduled task, and the program ends.

In the embodiment of the present invention, when the conflict detection module 30 performs the step of timing task conflict detection, if the newly added timing task conflicts with any existing timing task in the timing task rule library, it is considered that a timing task has occurred Conflict; if the newly added scheduled task does not conflict with all the existing scheduled tasks in the scheduled task rule base, the newly added scheduled task is considered to pass the detection and added to the scheduled task rule base.

Please refer to Fig. 2 again, after the linkage relationship between the new timing task and the existing timing task is established in the above steps, and after the conflict detection is performed, the conflict detection module 30 performs the steps of conflict resolution:

Step S105: task priority comparison; specifically, the conflict detection module 30 compares the new scheduled task with the existing scheduled task and evaluates the priority between the two, so as to allow the task execution module 50 to control the execution of the device entity Higher priority tasks.

The smart home system provided by the embodiment of the present invention applies a timing task conflict resolution device and a timing task conflict resolution method. When a user adds a new timing task, the new timing task and the existing timing task can be detected according to the timing task conflict detection mechanism. Whether there is a conflict between them, and can avoid the occurrence of timed task conflicts in the smart home system, and improve the stability and security of the smart home system. In addition, if there is no conflict between the new scheduled task set by the user and the existing scheduled tasks in the scheduled task rule base, the conflict detection module can add the new scheduled task to the scheduled task rule base according to the rule model. In the process, there is no need for software coders to customize rules, but the conflict detection module dynamically completes it, thereby reducing software maintenance costs and improving user experience.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art , without departing from the scope of the technical solution of the present invention, when the technical content disclosed above can be used to make some changes or be modified into equivalent embodiments with equivalent changes, but as long as it does not depart from the technical solution of the present invention, the technical content of the present invention In essence, any brief modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the technical solution of the present invention.
