[0001] This application relates to the field of communication technology, and in particular to a method and related equipment for a terminal device to access a power Internet of Things system. Background Technology

[0002] With the development of IoT technology and the increasing demand for electricity, power companies are gradually increasing their investment in the construction of power IoT systems. A power IoT system is the application of IoT technology in the power system. Terminal devices connect to the power IoT system through service nodes, achieving intelligent and networked connectivity.

[0003] In existing technologies, resource allocation methods for edge computing in the power Internet of Things (IoT) are based on a coarse-grained approach. Before a terminal device connects to the power IoT system, the service node to which it will connect is determined, and the service node can only connect to the next terminal device after the task on that terminal device is completed. However, with the development of power IoT systems, the massive number of terminal devices connected poses a severe challenge to existing resource allocation methods. This results in service nodes being unable to handle the tasks of multiple terminal devices simultaneously, leading to unreasonable resource allocation within the power IoT system and the inability to process the tasks of a massive number of terminal devices in a timely manner.

[0022] As described in the background section, with the development of IoT technology and the increasing demand for electricity, power companies are gradually increasing their investment in the construction of power IoT systems. A power IoT system is the application of IoT technology in the power system. Terminal devices access the power IoT system through service nodes, achieving intelligent and networked connectivity. Service nodes process data from terminal devices through power IoT edge computing. Power IoT edge computing is a technology that applies IoT and edge computing technologies to the power sector, contributing to the intelligentization, efficiency, and reliability of power systems.

[0023] In existing technologies, resource allocation methods for edge computing in the power Internet of Things (IoT) are based on a coarse-grained approach. Before a terminal device connects to the power IoT system, the service node it will connect to is determined, and the next terminal device can only connect after the task on that terminal device is completed and the service node is idle. However, with the development of power IoT systems, the massive number of terminal devices connected poses a severe challenge to existing resource allocation methods. Service nodes cannot handle the tasks of multiple terminal devices simultaneously, leading to unreasonable resource allocation in the power IoT system. The tasks of a massive number of terminal devices cannot be processed by the power IoT system in a timely manner, resulting in a waste of computing resources and failing to effectively adapt to the complexity of the underlying network and the dynamic and diverse resource demands of upper-layer users. Furthermore, existing computing resource allocation methods do not fully consider the load capacity of terminal devices on communication channels, thus failing to achieve reasonable resource allocation to meet the requirements of data transmission across different communication protocols.

[0024] In view of this, embodiments of this application propose a method for terminal devices to access a power Internet of Things (IoT) system, referring to... Figure 1 This includes the following steps:

[0025] Step 101: Receive the access request from the terminal device.

[0026] In this step, with the development of the Internet of Things (IoT), the power IoT system needs to handle tasks from a massive number of terminal devices, which can be, for example, sensor devices. Before the power IoT system processes the tasks of the terminal devices, the terminal devices need to send an access request to the power IoT system. The power IoT system receives the access request, which includes information related to the tasks to be processed by the terminal devices.

[0027] Step 102: Based on the access request, determine the communication channel between the terminal device and the power Internet of Things system and the communication protocol corresponding to the communication channel, and determine the resource allocation weight corresponding to the terminal device.

[0028] In this step, the communication channel serves as the data transmission path between the terminal device and the power IoT system. To ensure smooth and efficient data transmission from the terminal device, the communication resources provided by the channel must be greater than or equal to the communication resources required for data transmission. Therefore, based on the access request, the communication channel for the power IoT is determined. The access request reflects the communication resources required for the terminal device to transmit data from the tasks to be processed. The communication protocol refers to the rules and conventions that must be followed between the terminal device connected through the communication channel and the power IoT system to complete communication. The communication protocol defines the format used by data units, the information and meaning that information units should contain, the connection method, and the timing of information transmission and reception, thereby ensuring smooth data transmission. By determining the communication channel and communication protocol, smooth data transmission from the terminal device is ensured. The terminal device's access request also reflects the priority of tasks within the terminal device. Through resource allocation weights, resource allocation for the terminal device can be coordinated. When the task priority in the terminal device is relatively high, to ensure that the task is allocated sufficient computing resources to meet its processing needs, the resource allocation weight needs to be increased so that the terminal device can obtain sufficient computing resources in the power IoT system. It should be noted that when computing resources are insufficient in a power Internet of Things (IoT) system, the resource allocation weight for terminal devices with low task priority can be lowered. By determining the resource allocation weight, the goal of adjusting resource allocation for terminal devices can be achieved.

[0029] Step 103: Based on the access request and the resource allocation weight, determine the target service node that matches the terminal device from all service nodes in the power Internet of Things system.

[0030] In this step, the resources provided by the service nodes are limited, including computing and memory resources. To efficiently utilize the resources provided by the service nodes, a target service node matching the terminal device needs to be identified from all service nodes in the power communication system. All service nodes include both idle and active nodes. This is because when a service node is active, it may have surplus resources after deducting its occupied resources. Therefore, when determining the target service node matching the terminal device, it is necessary to select from all service nodes to ensure that the surplus resources of active service nodes are fully utilized. The idle resources of active service nodes can still provide resources for the terminal device about to connect. Furthermore, if the tasks of already connected terminal devices in the power IoT system are completed by a service node, the resources in that service node can promptly provide resources for the next connected terminal device. The access request and resource allocation weights of the terminal device reflect the resources ultimately required by the tasks within the terminal device, thus determining the target service node matching the terminal device from all service nodes. It should be noted that the resources provided by the target service node among all service nodes are closest to the computing resources required by the task in the terminal device. The resources provided by the target service node should be slightly greater than or equal to the resources required by the terminal device's task, ensuring full utilization of resources in the power Internet of Things (IoT) system. When multiple terminal devices share the same service node, by subdividing the resources of the service node, independent resource pools are allocated to different terminal devices, ensuring isolation and security between them and avoiding resource conflicts. By identifying the target service node that matches the terminal device among all service nodes, the goal of rationally allocating resources in the power IoT system is achieved.

[0031] Step 104: Control the terminal device to access the target service node in the power Internet of Things system through the communication channel and the communication protocol.

[0032] In this step, the terminal device can only transmit data to the power Internet of Things (IoT) system through a communication channel, and the data transmitted in the communication channel must follow the communication protocol. Therefore, after determining the target service node that matches the terminal device, the terminal device is controlled to access the target service node in the power IoT system through the communication channel and communication protocol. This enables the terminal device to transmit data to the power IoT system in a reasonable and efficient manner, and also improves the resource utilization rate of the power IoT system.

[0033] The above scheme receives the access request from the terminal device; based on the access request, it determines the communication channel and corresponding communication protocol between the terminal device and the power IoT system, ensuring smooth data transmission from the terminal device and determining the resource allocation weight for the terminal device, thus adjusting resource allocation for the terminal device. Based on the access request and the resource allocation weight, it identifies a target service node matching the terminal device from all service nodes in the power IoT system, achieving reasonable resource allocation within the power IoT system. Controlling the terminal device to access the target service node in the power IoT system through the communication channel and the communication protocol enables the terminal device to transmit data to the power IoT system reasonably and efficiently, while also improving resource utilization within the power IoT system.

[0034] In some embodiments, determining the communication channel between the terminal device and the power Internet of Things system and the corresponding communication protocol based on the access request includes: obtaining the remaining spectrum resources corresponding to the power Internet of Things system; determining the communication channel based on the remaining spectrum resources and the access request; obtaining the signal-to-noise ratio (SNR) of the terminal device and a preset communication protocol probability; determining the channel quality corresponding to the communication channel based on the SNR; and determining the communication protocol corresponding to the communication channel from all communication protocols corresponding to the power Internet of Things system based on the channel quality and the communication protocol probability.

[0035] In this embodiment, the power IoT system needs to allocate spectrum resources to the terminal devices to be connected, so that the data in the terminal devices can be successfully transmitted to the power IoT system. Spectrum resources refer to specific frequency ranges used for communication. First, the remaining spectrum resources corresponding to the power IoT system need to be obtained. Based on the access request of the terminal device, the target spectrum resource required by the terminal device is determined from the remaining spectrum resources, and then associated with the communication channel corresponding to the target spectrum resource, achieving the purpose of balanced allocation of the total communication channels in the power IoT system. It should be noted that the power IoT system can monitor the actual usage of each channel and periodically adjust communication resources dynamically when the load of the power IoT system changes significantly. If some channels have excess communication resources, the power IoT system can strip these resources and reallocate them to channels with higher loads. When a terminal device requests access to the power IoT system, the power IoT system can detect its communication needs. If there are idle communication resources in the power IoT system, corresponding communication resources can be allocated to the new terminal device; if there are insufficient idle communication resources in the power IoT system, the power IoT system can strip some existing channel communication resources to meet the communication needs of the terminal device. When depriving and reallocating channels, to ensure that the overall communication quality is not excessively affected, an SDN controller works in concert to ensure a smooth transition of channel switching and resource allocation, thereby minimizing disruption to the user experience.

[0036] The signal-to-noise ratio (SNR) is the ratio of the strength of the useful signal received by a terminal device to the strength of the received interference signal (noise and interference). It reflects the interference currently experienced by the terminal device from the outside world. The SNR determines the channel quality corresponding to the communication channel. Power IoT systems can monitor and evaluate the channel quality with terminal devices in real time. Channel quality helps service nodes optimize the use of communication resources, ensure efficient data transmission, and reduce packet loss and communication latency. Simultaneously, it can intelligently and adaptively adjust the communication protocol based on the channel quality of each terminal device to provide a better user experience. Determining the communication protocol corresponding to the communication channel based on channel quality is crucial because different communication protocols have different requirements for the power consumption management of terminal devices. For example, in cases of relatively poor channel quality, devices may need to listen to the channel more frequently or retransmit, thereby increasing power consumption and necessitating a change in the current communication protocol. Preset communication protocol probabilities can be configured in advance according to user needs to better adapt to the requirements of the power IoT system. For example, if a certain type of terminal device performs better when transmitting data using a particular communication protocol, that protocol can be assigned a higher probability; conversely, if a certain type of terminal device performs worse, it can be assigned a lower probability. Therefore, it is also necessary to obtain the corresponding preset communication protocol probabilities for each terminal device. These probabilities allow the terminal device to transmit data using the communication protocol that provides it with relatively better data transmission performance. It should be noted that different terminal devices can access the IoT terminal system through the same communication channel, and the communication protocols used by different terminal devices can be different, ensuring stable data transmission from different types of terminal devices to the power IoT system.

[0037] In some embodiments, determining the communication protocol corresponding to the communication channel from all communication protocols corresponding to the power Internet of Things system based on the channel quality and the communication protocol probability includes: adjusting the selection probability corresponding to each communication protocol in a pre-built communication protocol table based on the communication protocol probability to obtain a target selection probability corresponding to each communication protocol; determining the communication protocol corresponding to the channel quality in the communication protocol table based on the channel quality and the target selection probability, and identifying the communication protocol as the communication protocol corresponding to the communication channel.

[0038] In this embodiment, the pre-constructed communication protocol table is stored as a correlation table between channel quality and communication protocols. For example, when the channel quality falls within a certain interval, that interval corresponds to at least one communication protocol and its selection probability. Determining the communication protocol solely based on calculated channel quality is inaccurate because different types of terminal devices may have communication protocols that provide better data transmission performance. The selection probability of the communication protocol needs to be adjusted using the communication protocol probability to obtain the target selection probability. This increases the selection probability of the communication protocol that provides good data transmission performance for the terminal device and reduces the selection probability of the communication protocol that provides poor data transmission performance, thereby enabling the terminal device to transmit using the communication protocol that provides better data transmission performance.

[0039] In some embodiments, the access request includes the memory required by the task in the terminal device and the computing resources required by the task; determining the resource allocation weight corresponding to the terminal device based on the access request includes: determining the resource allocation weight using the following formula: Where, ω i Assign weights to the resources; The weight corresponding to the memory required for the task; Memory i Let β be the memory required for the task of the i-th terminal device, and t be the weight corresponding to the computing resources required for the task. i The computational resources required for the task of the i-th terminal device.

[0040] In this embodiment, the access request includes the memory and computing resources required by the task in the terminal device. The access request also carries information reflecting the importance of the memory and computing resources required by the task. Based on the above importance, the resource allocation weights are adjusted according to their respective weights, thereby reflecting the importance of the resource allocation weights and achieving the purpose of adjusting the resource allocation for the terminal device.

[0041] In some embodiments, the access request includes the memory and computing resources required by the task in the terminal device; determining the target service node matching the terminal device among all service nodes in the power Internet of Things system based on the access request and the resource allocation weight includes: determining the matching degree between the terminal device and all service nodes in the power Internet of Things system based on the access request; determining the matching probability of the service node based on the resource allocation weight and the matching degree; finding multiple service nodes whose available computing resources are greater than or equal to the required computing resources and whose available memory is greater than or equal to the memory required by the task; and finding the service node with the maximum matching probability among the multiple service nodes and determining that service node as the target service node.

[0042] In this embodiment, based on the access request, the matching degree between the terminal device and all service nodes in the power Internet of Things system is determined. This is used to measure whether the computing power of the service nodes is suitable for executing a specific task. Matching degree evaluation helps select the most suitable service node for executing the task on the terminal device, avoiding resource waste and performance degradation. The resource allocation weight reflects the priority of the terminal device; a higher priority terminal device receives a higher resource allocation weight, and vice versa. The matching probability of the service node is determined by the following formula:

[0043]

[0044] Where P(i,j) is the matching probability between the i-th terminal device and the j-th service node, ω i Weights are assigned to resources, where M(i,j) represents the matching degree between the i-th terminal device and the j-th service node, and n is the total number of service nodes. The service node with the highest matching probability is the most compatible with the terminal device. In this case, it's necessary to determine whether the node with the highest matching probability can execute the terminal device's task. Therefore, it's necessary to determine whether the computing resources provided by the service node are greater than or equal to the computing resources required by the terminal device, and whether the memory provided by the service node is greater than or equal to the memory required for the task. If both conditions are met, the node with the highest matching probability among the multiple service nodes satisfying these conditions is identified as the target service node. Identifying the target service node that best matches the terminal device ensures the rational allocation of resources in the power IoT system, improving resource utilization.

[0045] In some embodiments, determining the matching degree between the terminal device and all service nodes in the power Internet of Things system based on the access request includes: determining the matching degree using the following formula: Where M(i,j) represents the matching degree between the i-th terminal device and the j-th service node, Memory i Memory is the memory required for the task of the i-th terminal device. j For the memory that the j-th service node can provide, t i For the computing resources required for the task of the i-th terminal device, t j Let j represent the computing resources that the j-th service node can provide. β represents the weight corresponding to the memory required by the task, and β represents the weight corresponding to the computing resources required by the task.

[0046] In this embodiment, the matching degree between the terminal device and each service node in the power Internet of Things (IoT) system can be determined using a formula. This not only compensates for the lack of rational resource allocation at the terminal device but also allocates resources within the power IoT system more rationally by calculating the matching degree. Furthermore, by integrating network and computational characteristics, the power IoT system can efficiently handle even complex and variable environments at the underlying access network of the terminal device. It should be noted that the formula demonstrates that for a high matching degree between the terminal device and the service node, the resources provided by the service node must be slightly greater than or equal to the resources required for the terminal device's task, ensuring full utilization of resources within the power IoT system.

[0047] In some embodiments, determining the channel quality corresponding to the communication channel based on the signal-to-noise ratio includes: determining the channel quality using the following formula: CQ i =k×log(SNR) i ), of which CQ i The channel quality is defined as k, where k is a preset adjustment parameter, and log(SNR) is the channel quality. i ) represents the logarithmic signal-to-noise ratio of the i-th terminal device.

[0048] In this embodiment, SNR i SNR represents the signal-to-noise ratio of the i-th terminal device. i Effective calculations require consideration of signal and noise characteristics. The function f(.) is a mapping function that maps the signal-to-noise ratio (SNR) to the corresponding channel quality. The specific form of this function needs to be determined based on the design and performance requirements of the power IoT system. If wireless communication standards such as Wi-Fi, Bluetooth, LoRa (Long Range Low Energy Radio Frequency), and NB-IoT (Narrowband Internet of Things) are used, the SNR is processed through the function f(.). i It can be expressed using the logarithmic signal-to-noise ratio, i.e., log(SNR). i In this formula, the logarithmic signal-to-noise ratio (SNR) is typically used to describe the relative strength of the signal and noise in a terminal device. k is a preset adjustment parameter, a constant that adjusts the relationship between the SNR and channel quality; this adjustment needs to be observed and adjusted through on-site testing. By quantifying channel quality using this formula, the goal of accurately determining channel quality is achieved.

[0049] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

[0050] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0051] Based on the same inventive concept, corresponding to any of the above embodiments, this application also provides a device for terminal equipment to access a power Internet of Things system.
