Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
As shown in fig. 1, a schematic flow chart of an embodiment of an energy saving method for a node of an internet of things provided by the present invention is shown, specifically, the node of the internet of things includes a plurality of tasks to be processed, where the tasks to be processed include an instant task and a non-instant task (at least one), and the instant task and the non-instant task both arrive at the node of the internet of things under a random condition, and the processing time is separated and asynchronous.
As can be seen from the figure, the energy saving method for the nodes of the internet of things comprises the following steps: s1, the node of the Internet of things starts to process the instant task; s2, the node of the Internet of things judges the load state of the microprocessing unit when processing the instant task; s3 the node of Internet of things judges whether to process non-instant tasks except the instant tasks according to the judgment result of the step S2; and S4 the node of the Internet of things simultaneously processes a plurality of tasks according to the judgment result of the step S3, so that the energy conservation of the node of the Internet of things is realized.
In this embodiment, immediately after the internet of things node starts processing the instant task, according to whether the node can simultaneously process the non-instant task in the load state of processing the instant task, if it is determined that the instant task and the non-instant task can be simultaneously processed, the non-instant task is not processed, and only the instant task is processed. Specifically, if the load state of the micro processing unit is smaller than the preset load threshold when the internet of things node processes the instant task, which indicates that the micro processing unit can process the non-instant task at the same time, the load state of the micro processing unit when the non-instant task is processed is further judged, and at least one non-instant task, the load state of which is smaller than the preset load threshold when the micro processing unit processes the instant task at the same time, is selected according to the judged load state and is processed at the same time. It should be noted that, here, the preset load threshold is not specifically limited, and for example, the preset load threshold is 70% or 80% of the full load, and can be set by itself according to the actual situation.
In one example, the internet of things node includes an immediate task and a non-immediate task, and the preset load threshold is 80% of the full load. When the node of the Internet of things starts to process the instant task, judging the load state of the node of the Internet of things, and if the load state of processing the instant task is judged to be 50% to 80% of the full load; and further judging the load state of the non-immediate task, and if the load state of the non-immediate task is judged to be 10% of the full load. Therefore, the micro-processing unit in the node of the internet of things can process the instant task and the non-instant task at the same time (50% + 10% < 80%), so that the node of the internet of things can process the instant task and the non-instant task at the same time. In this example, if it is determined that the load state in which the non-immediate task is processed is 40% (50% + 40% > 80%) of the full load, only the immediate task is processed without processing the non-immediate task at that time.
In another example, the internet of things node includes one immediate task and two non-immediate tasks (including a first task and a second task), and the preset load threshold is 70% of the full load. When the node of the Internet of things starts to process the instant task, judging the load state of the node of the Internet of things, and if the load state of processing the instant task is judged to be 50% to 70% of the full load; further, the load state of the processing of the non-immediate task is judged, and if the load state of the processing of the first task is judged to be 25% of the full load, the load state of the processing of the second task is judged to be 10% of the full load. Then, according to the judgment result, it is judged that the micro-processing unit in the node of the internet of things can process the instant task and the second task at the same time (50% + 10% < 70%), so that the node of the internet of things can process the instant task and the second task at the same time.
As shown in fig. 2, in the embodiment, the method for saving energy for a node of the internet of things includes: s1, the node of the Internet of things starts to process the instant task; s2 the node of Internet of things judges the time length for processing the instant task and the load state of the micro-processing unit in the node of Internet of things when processing the instant task; s3 the node of Internet of things judges whether to process non-instant tasks except the instant tasks according to the judgment result of the step S2; and S4 the node of the Internet of things simultaneously processes a plurality of tasks according to the judgment result of the step S3, so that the energy conservation of the node of the Internet of things is realized.
In this embodiment, immediately after the node of the internet of things starts to process the instant task, whether the non-instant task can be processed simultaneously is determined according to the load state of the node of the internet of things in processing the instant task (including the determination of the load state and the processing duration), if the node of the internet of things determines that the instant task and the non-instant task can be processed simultaneously, the non-instant task is processed simultaneously, otherwise, the non-instant task is not processed, and only the instant task is processed. Specifically, if the load state of the micro processing unit is smaller than the preset load threshold when the internet of things node processes the instant task and the time length of the internet of things node for processing the instant task is greater than the preset time threshold, which indicates that the micro processing unit can process the non-instant task at the same time, the load state of the micro processing unit when the non-instant task is processed is further judged, and at least one non-instant task of which the load state is smaller than the preset load threshold when the instant task is processed at the same time is selected according to the judged load state and is processed at the same time. In this embodiment, the preset load threshold and the preset time threshold are not specifically limited, and for example, the preset load threshold is 70% or 80% of the full load, and the preset time threshold is set to 60s (seconds) or 0.5h (hours), and can be set by the user according to the actual situation. In addition, in the embodiment, the processing time of the non-instant task is not specifically limited, and the processing time may even be longer than a preset time threshold, and at this time, the internet of things node may continue to complete the processing of the non-instant task after processing the instant task, so that the processing time and the electric quantity can be saved as well.
In one example, the internet of things node includes an instant task and a non-instant task, and the preset load threshold is 80% of the full load, and the preset time threshold is 60 s. When the node of the Internet of things starts to process the instant task, judging the load state of the node of the Internet of things, and if the load state of processing the instant task is judged to be 50% to 80% of the full load, the processing time is 70 s; the load state of processing the non-immediate task is further judged, and if the load state of processing the non-immediate task is judged to be 10% of the full load (at the moment, the processing time length of the non-immediate task is not judged). Therefore, the micro-processing unit in the node of the internet of things can process the instant task and the non-instant task at the same time (50% + 10% < 80%), so that the node of the internet of things can process the instant task and the non-instant task at the same time.
Based on this, in another embodiment, after determining that the micro-processing units can simultaneously process the non-immediate tasks, the load status of the micro-processing units when processing the non-immediate tasks is further determined, and at least one non-immediate task whose load status is smaller than the preset load threshold and whose processing duration is smaller than the processing duration of the immediate tasks is selected according to the determined load status when simultaneously processing the immediate tasks.
In one example, the internet of things node comprises an instant task and two non-instant tasks (including a first task and a second task), and the preset load threshold is 70% of the full load; the preset time threshold is 60s, the processing time of the instant task is 70s, the processing time of the first task is 30s, and the processing time of the second task is 80 s. When the nodes of the internet of things start to process the instant tasks, judging the load state of the nodes of the internet of things, and if the load state of the nodes of the internet of things is judged to be 50% to 70% of the full load, the processing time is 70s and is greater than a preset time threshold value 60 s; the load status of processing the non-immediate task is further determined, and if the load status of processing the first task is determined to be 25% of full load, the load status of processing the second task is determined to be 10% of full load. It can be known that the micro-processing unit in the node of the internet of things cannot process the instant task and the non-instant task at the same time (wherein, the processing time of the first task is 50% + 25% > 80%, and the processing time of the second task is 80s >70s), so that the node of the internet of things only processes the instant task at the moment.
In another example, the internet of things node includes an instant task (specifically, a local task, which takes 60s, and the load status of the processing process is 50% of the full load) and a non-instant task (specifically, a remote task, which downloads a file from a server to the internet of things node, which takes 30s, and the load status of the processing process is 10% of the full load), the preset load threshold is 70% of the full load, and the preset time threshold is 50s, as shown in fig. 3, the instant task and the non-instant task are executed at different time periods, where a represents an instant task execution time, and B represents a non-instant task execution time. When the micro-processing unit in the node of the internet of things starts to process the instant task, an indication message is sent to the server, the micro-processing unit is identified to be in a working state within a long time period, and the server immediately sends a file to the node of the internet of things, so that the network node starts to process the non-instant task while processing the instant task, as shown in fig. 4. Therefore, the total time of the micro-processing unit for simultaneously processing the instant task and the non-instant task is 60s < the sum of the time for separately processing the instant task and the non-instant task is <90s, so that the time of the micro-processing unit in a working state is saved, and the electric quantity is saved.
Fig. 5 is a schematic diagram of an embodiment of an energy saving device 100 for a node of the internet of things, which is applied to the energy saving method for a node of the internet of things, specifically, the node of the internet of things includes a plurality of tasks to be processed, where the tasks to be processed include an instant task and a non-instant task (at least one), and the instant task and the non-instant task both arrive at the node of the internet of things at random, and the processing times are separated and asynchronous; in addition, the instant task is specifically a task which is required to be executed by the node of the internet of things currently, and the non-instant task is a task which is not required to be executed by the node of the internet of things currently and is only required to be executed within a certain time, such as within 24 h.
As can be seen from the figure, the internet of things node energy saving device 100 includes a task processing module 110 and a determining module 120 connected to each other. Specifically, in the working process, after the internet of things node starts to process the instant task, it is immediately determined whether the module 120 can simultaneously process the non-instant task in the load state of processing the instant task, if it is determined that the instant task and the non-instant task can be simultaneously processed, the task processing module 110 simultaneously processes the non-instant task, otherwise, the non-instant task is not processed, and only the instant task is processed.
As shown in fig. 6, in this embodiment, the energy saving device 100 of a node of the internet of things further includes a selecting module 130 in addition to the task processing module 110 and the determining module 120. Specifically, in the working process, if the determining module 120 determines that the load state of the micro processing unit is smaller than the preset load threshold when processing the instant task, which indicates that the micro processing unit can process the non-instant task at the same time, the determining module further determines the load state of the micro processing unit when processing the non-instant task, so that the selecting module 130 selects at least one non-instant task whose load state is smaller than the preset load threshold when processing the instant task at the same time according to the determined load state, and the task processing module 110 processes the non-instant tasks at the same time. It should be noted that, here, the preset load threshold is not specifically limited, and for example, the preset load threshold is 70% or 80% of the full load, and can be set by itself according to the actual situation.
In this embodiment, after the internet of things node starts to process the instant task, the immediate judgment module 120 judges whether the non-instant task can be processed simultaneously (including the judgment of the load state and the processing duration) according to the load state of the immediate task, if the immediate task and the non-instant task can be processed simultaneously, the task processing module 110 processes the non-instant task simultaneously, otherwise, the non-instant task is not processed, and only the immediate task is processed. Specifically, if the determining module 120 determines that the load state of the micro processing unit is smaller than the preset load threshold when the real-time task is processed and the time duration for processing the real-time task by the node of the internet of things is greater than the preset time threshold, it indicates that the micro processing unit can process the non-real-time tasks at the same time, and further determines the load state of the micro processing unit when the non-real-time tasks are processed, so that the selecting module 130 selects at least one non-real-time task whose load state is smaller than the preset load threshold when the real-time task is processed at the same time according to the determined load state, and the task processing module 110 processes the non-.
In this embodiment, after the internet of things node starts to process the instant task, the immediate judgment module 120 judges whether the non-instant task can be processed simultaneously (including the judgment of the load state and the processing duration) according to the load state of the immediate task, if the immediate task and the non-instant task can be processed simultaneously, the task processing module 110 processes the non-instant task simultaneously, otherwise, the non-instant task is not processed, and only the immediate task is processed. Specifically, after the determining module 120 determines that the micro-processing units can process the non-immediate tasks simultaneously, the load status of the micro-processing units when processing the non-immediate tasks is further determined, the selecting module 130 selects at least one non-immediate task whose load status is smaller than the preset load threshold and whose processing duration is smaller than the processing duration of the immediate tasks when processing the immediate tasks simultaneously according to the determined load status, and the task processing module 110 processes the non-immediate tasks simultaneously.
In another example, the internet of things node includes an instant task (specifically, the internet of things node is a sweeping robot, the instant task is sweeping by the sweeping robot, the time consumption is 60s, and the load state of the processing process is 50% of a full load) and a non-instant task (specifically, a remote task, an upgrade file is downloaded from a server, the time consumption is 30s, and the load state of the processing process is 10% of the full load), the preset load threshold is 70% of the full load, and the preset time threshold is 50 s. When the sweeping robot starts sweeping, an indication message is sent to the server, the identification micro-processing unit is in a working state for a long time, the server immediately sends the upgrade file to the sweeping robot, and the sweeping robot downloads the upgrade file at the same time when sweeping, so that the time that the micro-processing unit in the sweeping robot is in the working state is saved, and power consumption is saved.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
