Description

Technical Field

[0001] This invention relates to the field of industrial Internet of Things (IoT) technology, and in particular to a low-latency IoT implementation method. Background Technology

[0002] With the development of IoT technology in industrial technology, the connections between various devices are becoming increasingly close. In many cases, multiple devices need to coordinate to complete a task. The coordination methods are generally parallel and serial. In particular, when using the serial method, the next device usually receives the information sent by the previous device after the previous device has finished processing the corresponding task, and then proceeds to the next task. This makes the entire execution process relatively long. Summary of the Invention

[0003] This invention provides a low-latency Internet of Things (IoT) implementation method, which aims to reduce the time it takes for information to be processed between various devices, thereby reducing latency.

[0004] To achieve the above objectives, the present invention provides a low-latency Internet of Things (IoT) implementation method, applied to an IoT system. The IoT system includes multiple devices and a central controller. The multiple devices include a first device, a second device, and a third device. The multiple devices and the central controller are communicatively connected to form an IoT network. The low-latency IoT implementation method is executed on the multiple devices and the central controller, and includes the following steps:

[0005] Step S10: The first device receives the first information and simultaneously forwards the first information to the central controller;

[0006] Step S20: While the first device is processing the first request information, the central controller predicts the processing methods corresponding to the second device and the third device based on the first information.

[0007] Step S30: The second device and the third device prepare for the corresponding processing method based on the prediction result of the central controller;

[0008] Step S40: After receiving the second information processed by the first device, the second device determines whether its processing method is the processing method predicted by the central controller.

[0009] Step S50: If not, the second device shall process the data using the corresponding processing method and simultaneously send the prediction failure and the second information to the central controller.

[0010] Step S60: While the second device processes the second information, the central controller predicts the processing method of the third device based on the second information and sends the prediction result to the third device.

[0011] Step S70: The third device prepares for the corresponding processing method based on the prediction result of the central controller.

[0012] Step S80: After receiving the third information processed by the second device, the third device determines whether its processing method is the processing method predicted by the central controller. If so, the third device processes the third information according to the processing method predicted by the central controller. If not, the third device processes the information using the corresponding processing method.

[0013] Optionally, step S40 may be followed by:

[0014] Step S41: If yes, then the second device processes the second information according to the processing method predicted by the central controller.

[0015] Optionally, in step S20, the central controller predicts multiple processing methods, and the multiple processing methods are arranged according to probability;

[0016] In step S40, the second device and the third device perform preparation work corresponding to the processing method in sequence according to the probability.

[0017] Optionally, the central controller predicts no more than three processing methods for each of the second and third devices.

[0018] Optionally, after step S30, the method further includes:

[0019] Step S31: The central controller estimates the time for the first device to process the first information to obtain time t1, and estimates the preparation time for the second device to obtain time t2.

[0020] Step S32: When t2 is greater than t1 and t2-t1 is greater than the first set value, the central controller assists the second device in preparing for the corresponding processing mode.

[0021] Optionally, after step S70, the method further includes:

[0022] Step S71: The central controller estimates the time for the second device to process the second information to obtain time t3, and estimates the preparation time for the third device to obtain time t4.

[0023] Step S72: When t4 is greater than t3 and t4-t3 is greater than the second set value, the central controller assists the third device in preparing for the corresponding processing mode.

[0024] The technical solution proposed in this invention includes the following steps for implementing a low-latency Internet of Things (IoT): Step S10: A first device receives first information and simultaneously forwards the first information to a central controller; Step S20: While the first device processes the first request information, the central controller predicts the processing methods corresponding to the second device and the third device based on the first information; Step S30: The second device and the third device prepare for the corresponding processing methods based on the prediction results of the central controller; Step S40: After receiving the second information processed by the first device, the second device determines whether its processing method is the processing method predicted by the central controller; Step S50: If not, the second device processes the information using the corresponding processing method and simultaneously sends a prediction failure message and a second message to the central controller; Step S60: While the second device processes the second information... In step S70, the central controller predicts the processing method of the third device based on the second information and sends the prediction result to the third device; in step S80, the third device prepares for the corresponding processing method based on the prediction result of the central controller; in step S80, after receiving the third information processed by the second device, the third device determines whether its processing method is the processing method predicted by the central controller. If so, the third information is processed according to the processing method predicted by the central controller; if not, the third device uses the corresponding processing method. That is, in this application, while the previous device is performing related processing work, the central controller predicts the work of the subsequent device so that the subsequent device can prepare in advance, so that the subsequent preparation work can be carried out in parallel with the previous processing work. In this way, the processing time of each device can be reduced, thereby reducing the latency of the entire Internet of Things system. Attached Figure Description

[0032] This invention provides a low-latency Internet of Things (IoT) implementation method applied to an IoT system. The IoT system includes multiple devices and a central controller. The multiple devices include a first device, a second device, and a third device. The multiple devices and the central controller are communicatively connected to form an IoT. The low-latency IoT implementation method is executed on the multiple devices and the central controller.

[0033] The low-latency Internet of Things (IoT) implementation method includes the following steps:

[0034] Step S10: The first device receives the first information and simultaneously forwards the first information to the central controller;

[0035] Step S20: While the first device is processing the first request information, the central controller predicts the processing methods corresponding to the second device and the third device based on the first information.

[0036] Step S30: The second device and the third device prepare for the corresponding processing method based on the prediction result of the central controller;

[0037] Step S40: After receiving the second information processed by the first device, the second device determines whether its processing method is the processing method predicted by the central controller.

[0038] Step S50: If not, the second device shall process the data using the corresponding processing method and simultaneously send the prediction failure and the second information to the central controller.

[0039] Step S60: While the second device processes the second information, the central controller predicts the processing method of the third device based on the second information and sends the prediction result to the third device.

[0040] Step S70: The third device prepares for the corresponding processing method based on the prediction result of the central controller.

[0041] Step S80: After receiving the third information processed by the second device, the third device determines whether its processing method is the processing method predicted by the central controller. If so, the third device processes the third information according to the processing method predicted by the central controller. If not, the third device processes the information using the corresponding processing method.

[0042] The technical solution proposed in this invention includes the following steps for implementing a low-latency Internet of Things (IoT): Step S10: A first device receives first information and simultaneously forwards the first information to a central controller; Step S20: While the first device processes the first request information, the central controller predicts the processing methods corresponding to the second device and the third device based on the first information; Step S30: The second device and the third device prepare for the corresponding processing methods based on the prediction results of the central controller; Step S40: After receiving the second information processed by the first device, the second device determines whether its processing method is the processing method predicted by the central controller; Step S50: If not, the second device processes the information using the corresponding processing method and simultaneously sends a prediction failure message and a second message to the central controller; Step S60: While the second device processes the second information... In step S70, the central controller predicts the processing method of the third device based on the second information and sends the prediction result to the third device; in step S80, the third device prepares for the corresponding processing method based on the prediction result of the central controller; in step S80, after receiving the third information processed by the second device, the third device determines whether its processing method is the processing method predicted by the central controller. If so, the third information is processed according to the processing method predicted by the central controller; if not, the third device uses the corresponding processing method. That is, in this application, while the previous device is performing related processing work, the central controller predicts the work of the subsequent device so that the subsequent device can prepare in advance, so that the subsequent preparation work can be carried out in parallel with the previous processing work. In this way, the processing time of each device can be reduced, thereby reducing the latency of the entire Internet of Things system.

[0043] In one embodiment of the present invention, the method further includes the following step after step S40:

[0044] Step S41: If yes, then the second device processes the second information according to the processing method predicted by the central controller; because in industry, the common processing methods of each device are predetermined, and the central controller can generally accurately predict the operation of subsequent devices. Under normal circumstances, subsequent devices, such as the second and third devices, can operate according to the predicted processing method.

[0045] In one embodiment of the present invention, in step S20, the central controller predicts multiple processing methods, and the multiple processing methods are arranged according to probability.

[0046] In step S40, the second device and the third device perform preparation work corresponding to the processing method in sequence according to the probability.

[0047] Generally, given a given piece of information, it is not possible to completely predict a single processing method; that is, there may be multiple scenarios. Thus, the central controller predicts multiple processing methods, and the central processor arranges these multiple processing methods according to probability to facilitate the subsequent preparation of equipment.

[0048] In one embodiment of the present invention, the central controller predicts no more than three processing methods for each of the second and third devices. Generally, three or fewer methods are sufficient to accurately predict the processing method; if the number is too large, the subsequent preparation time will be too long, and consequently, there is no advantage in terms of time.

[0049] In one embodiment of the present invention, after step S30, the method further includes:

[0050] Step S31: The central controller estimates the time for the first device to process the first information to obtain time t1, and estimates the preparation time for the second device to obtain time t2.

[0051] Step S32: When t2 is greater than t1, and t2-t1 is greater than the first set value, the central controller assists the second device in preparing for the corresponding processing mode. This avoids affecting the overall progress due to the second device's excessive preparation time.

[0052] In one embodiment of the present invention, after step S70, the method further includes:

[0053] Step S71: The central controller estimates the time for the second device to process the second information to obtain time t3, and estimates the preparation time for the third device to obtain time t4.

[0054] Step S72: When t4 is greater than t3 and t4-t3 is greater than the second set value, the central controller assists the third device in preparing for the corresponding processing mode.

[0055] This can avoid affecting the overall progress due to the excessive preparation time of the third device.

[0056] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.
