[0025] Traditional fiber-optic communication and other wired methods have huge investment costs and are limited by geographical and environmental factors, making it difficult to achieve full coverage. With the continuous development of communication technology, the existing wired or wireless communication methods are becoming more mature. In order to support the evolution of information technology towards IoT and intelligence, the need to achieve the interconnection of all things and human-computer interaction in new business scenarios such as smart substations, distributed new energy, and integrated energy in parks on the low-voltage side of the power grid, as well as the need to share and integrate professional data and fully connect businesses has become increasingly urgent. At present, the application and construction of multiple wireless communication technologies such as WiFi, Lora, and NB-IoT that support large bandwidth, wide coverage, and low power consumption have been widely carried out.

[0026] Hundreds of millions of terminal devices will be connected to the power Internet of Things network, and more than 100 billion daily network traffic will be generated during the collection and interaction process. Since there are a large number of business terminals in the densely covered area of ​​the low-voltage side network, there is a demand for ubiquitous connection, which leads to a decrease in data transmission rate, an increase in transmission delay, and an increase in transmission energy consumption per bit. Since the deployment of power business terminals is affected by human factors and geographical factors, it is unevenly distributed. Therefore, the densely deployed communication access points (APs) have different loads. When the AP load is high, there are fewer remaining dispatchable resources, which leads to excessive energy consumption and increased response time. Secondly, due to the high complexity of the low-voltage side IoT scene, the uncertainty of channel conditions is large, which is also one of the factors causing increased energy consumption. It is urgent to solve the problem of excessive power consumption caused by massive device access and channel blocking, improve the communication quality between business terminals and cloud master stations, and reduce the energy consumption overhead of the communication system.

[0027] Based on the above technical problems, the present invention proposes a method for integrating communication on the low-voltage side of power, which determines the communication power consumption based on the transmission power consumption of the current service and the transmission power consumption of the access point AP, determines the AP that needs to be enabled within the current service scope based on the communication power consumption and enables it, and then determines the AP associated with the current service based on the data transmission volume of the enabled AP within the service scope corresponding to the current service, and finally transmits the current service through the AP associated with the current service. With the goal of optimizing the overall energy consumption of low-voltage side IoT communication, reasonable communication access scheduling is achieved from the perspective of AP enablement and service terminal-AP association mapping, so as to reduce the overall communication energy consumption while meeting service needs.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] With the development of new power systems, low-voltage IoT terminals are rapidly emerging in various application scenarios, including inspection robots, surveillance cameras, low-voltage switches, etc., each with different access methods, and the agreed terminals may have multiple types of communication interfaces. In recent years, wireless access points have become the development trend of low-voltage IoT networking. WiFi, Lora, and Zigbee access points (APs) have been widely deployed due to their convenience and gradually improved stability. Under the wave of power cloud-edge-end collaborative construction, in order to realize local analysis and intelligent decision-making of various IoT sensors and collection terminals, edge IoT agents, 5G MEC, etc. have become key edge nodes in power IoT application scenarios, providing local low-latency, high-reliability services and refined management for unified access business terminals. Figure 1 This is a diagram of the low-voltage side fusion communication architecture of the power system provided by the present invention, such as Figure 1 As shown, edge-side facilities are connected to the business system through the power communication network, and the business system implements global decision-making and regulation in the form of a cloud platform.

[0030] In terms of the energy consumption of low-voltage integrated communications, the scheduling of terminals, access points and edge sides is controllable for power companies, especially the energy consumption of ubiquitous communication access networks composed of multiple types of APs in the power industry has great room for unified optimization. There are two key issues: (1) Decision-making problem on the number of active APs. How to determine the appropriate number of active APs? The number of APs required varies depending on the number of service terminals accessing different areas. If there are many service terminals requesting access but few APs, the transmission delay will increase and even cause network congestion. At the same time, if there are no enabled APs in the requested area, communication services cannot be provided and the task requests of the service terminals cannot be met. Otherwise, the system energy consumption will increase and communication resources will be wasted.

[0031] (2) The problem of associating and mapping service terminals with APs. In order to meet the access communication needs during peak hours, APs need to be densely deployed. Therefore, some service terminals will have multiple APs as their access candidate nodes, and choosing different APs to access will affect the size of the spectrum resources they obtain, which in turn affects the access choices of other service terminals. On the other hand, the service terminal's choice of different APs to access will change the AP's active state. Therefore, how to effectively associate service terminals with appropriate AP nodes to make communication resource scheduling more reasonable, reduce the transmission energy consumption on the device side, and thus reduce system energy consumption is a key issue.

[0032] In short, for an AP in working state, its adjacent APs exist in two states: on or off. When the state is on, the mapping relationship between the service equipment and the AP is dynamically scheduled to reduce the transmission energy consumption of the service terminal; when the state is off, it is necessary to weigh the working energy consumption of the AP and the transmission energy consumption saved for the service terminal after it is turned on, and finally determine the working state of the AP.

[0033] Figure 2 It is a flow chart of the electric power low voltage side fusion communication method provided by the present invention, such as Figure 2 As shown, the present invention provides a low-voltage side fusion communication method for electric power, the method comprising: Step 201: Determine communication power consumption based on the transmission power consumption of the current service and the transmission power consumption of the access point AP.

[0034] Specifically, consider a low-voltage side IoT networking scenario within a specific range. In this scenario, there are multiple business terminals, each of which may undertake multiple specific businesses, and different business terminals may use different communication technologies.

[0035] For example, to model the low-voltage side IoT terminals: the number of business terminals is ( is a positive integer), business terminal set ; Each business terminal undertakes multiple specific businesses, and the total number of businesses is ( is a positive integer); terminal The corresponding business set is , For Terminal The number of businesses undertaken; Divided into the following three types: (1) Sensor business : With fixed period Transmission, the amount of data transmitted each time is constant The rest of the time is when there is no transmission demand.

[0036] (2) QoS (Quality of Service) services : Time period Within a certain period of time, the transmission demand is subject to the arrival rate The amount of data transmitted each time also follows the Poisson distribution with parameter Poisson distribution. The rest of the time is a state of no transmission demand.

[0037] (3) Delay-sensitive services :The AP needs to be available at any time. The single data transmission volume is a small constant. .

[0038] Modeling the communication access network: Consider APs, A converged access network consisting of various communication technologies. , , represents the i-th type of AP (i.e. ) ); Considering that the same AP has multiple communication technologies, define The communication technology set is ; In terms of communication resources, define China Communications Technology The number of communication resource blocks that can be called is , the spectrum size of each resource block is .

[0039] Define the connectivity matrix as . Indicates terminal Able to support Access technology, otherwise it is not supported.

[0040] Define the connection range matrix as . Indicates terminal In of The access scope of the access technology, otherwise it is not within the access scope.

[0041] In an embodiment of the present application, the transmission power consumption of the terminal is determined based on the communication transmission delay of the service and the transmission power consumption of transmitting the service.

[0042] For example, considering the transmission energy consumption of a specific service in a time period T, the transmission power consumption on the terminal side is:

[0043] in:

[0044] In the formula, Represents the terminal side service set in period 𝑇 The transmission power consumption is Indicates business In cycle The communication transmission delay within Indicates that the terminal is in the process of transmission Adopting communication technology The transmission power consumption is . The transmission data volume is defined as bit, which can be obtained according to three types of services. The access spectrum bandwidth size is ; The signal-to-noise ratio in a communication system is defined as ,in yes The receiver noise figure is is the thermal noise coefficient of the terminal equipment itself, is the road loss coefficient.

[0045] In the embodiment of the present application, three states of AP transmission, working and sleeping are considered. The transmission state refers to the AP being in the actual business data transmission and reception, the working state refers to the AP not performing effective data transmission, but being in a low energy consumption state of intermittently sending management frames or maintaining monitoring, and the sleeping state refers to the AP keeping the communication module turned off for a period of time when there is no foreseeable transmission demand in order to reduce energy consumption, and only waking up by itself according to the expected strategy. Representative technologies include WiFi timed wake-up mechanism (Target Wake Time, TWT), 5G discontinuous reception (Discontinuous Reception, DRX), etc.

[0046] The energy consumption on the AP side is defined as:

[0047] In cycle Total energy consumption It is the sum of the products of power consumption and duration of the three modes. , , Take the given values ​​to represent the power consumption of the AP in the sleep, working and transmission states. is the data transmission time of all services carried by the AP, which can be expressed as . The working time that the AP needs to maintain to serve the current service set. If it is within the transmission demand range of any sensor service or QoS service, then ; When there are delay-sensitive services, the AP needs to keep working all the time. . In addition to working and transmitting states, the AP can temporarily shut down the communication function and keep dormant for a period of time. .

[0048] For areas covered by multiple APs, the communication resources obtained by the power business terminal are also limited by the number of APs turned on. At the same time, the number of active APs enabled will affect the overall energy consumption of the system, and it is necessary to find energy-saving strategies in a combinatorial optimization manner. Therefore, according to the above problem description, the energy-saving problem of the Internet of Things transmission task can be regarded as a knapsack problem. To facilitate the solution, this problem is redefined as a mixed integer linear programming problem.

[0049] The goal of the power optimization problem is to minimize the given cycle The sum of the transmission energy consumption of each service on the internal terminal side and the service energy consumption on the AP side:

[0050] In the formula, represents the overall communication power consumption of the system within period 𝑇; Represents the terminal side service set in period 𝑇 Transmission power consumption; In the period 𝑇 transmission power consumption.

[0051] Specifically, for the current service, the communication power consumption is determined based on the transmission power consumption of the current service and the transmission power consumption of the access point AP, so that access scheduling is performed with the goal of minimizing the communication power consumption.

[0052] Step 202: Determine the AP that needs to be enabled within the current service scope based on the communication power consumption and enable it.

[0053] Specifically, the APs that need to be enabled within the current business scope are determined based on communication power consumption, that is, whether an AP needs to be enabled for the current business and which AP(s) to enable are determined with the goal of minimizing communication power consumption, and the APs that are confirmed to need to be enabled are enabled.

[0054] The enabled AP is an active AP, which refers to an AP in a non-dormant state.

[0055] Step 203: Determine the AP associated with the current service based on the data transmission volume of the enabled APs within the service range corresponding to the current service.

[0056] Specifically, after determining the enabled AP, the AP associated with the current service is determined based on the data transmission volume of the enabled AP within the service range corresponding to the current service. The data transmission volume of the AP refers to the data transmission volume that the AP can carry.

[0057] For example, for current business ,Sure The enabled APs within the corresponding service range include: , , known The remaining amount of resources and The remaining amount of resources is known. Data transmission capacity and The data transmission capacity is based on Data transmission capacity and The data transmission capacity determines the AP associated with the current service. still .

[0058] Step 204: Transmit the current service through the AP associated with the current service.

[0059] Specifically, after determining the AP associated with the current service, the current service is transmitted based on the AP, thereby achieving smooth transmission of service data and reducing communication power consumption.

[0060] The electric power low-voltage side integrated communication method provided in the embodiment of the present application determines the communication power consumption based on the transmission power consumption of the current service and the transmission power consumption of the access point AP, determines the AP that needs to be enabled within the current service scope based on the communication power consumption and enables it, and then determines the AP associated with the current service based on the data transmission volume of the enabled AP within the service scope corresponding to the current service, and finally transmits the current service through the AP associated with the current service. With the goal of optimizing the overall energy consumption of low-voltage side IoT communication, reasonable communication access scheduling is achieved from the perspective of AP enablement and service terminal-AP association mapping, so as to reduce the overall communication energy consumption while meeting service needs.

[0061] In some embodiments, the method further comprises: When the number of APs within the service range corresponding to the current service is 1, the AP is enabled, and it is determined that the association relationship between the current service and the AP is one-to-one.

[0062] Specifically, when making an AP activation decision, first determine whether the number of APs in the service range corresponding to the current service is 1. If it is 1, the AP is activated, and the association relationship between the current service and the AP is determined to be one-to-one, and the remaining resources of the AP are updated. If it is not 1, it is necessary to further process the access scheduling problem of the overlapping service set area.

[0063] The low-voltage side converged communication method provided in the embodiment of the present application first considers the situation of APs that have to be turned on, that is, APs whose mapping relationship cannot be selected and have to be enabled. That is, when there is only one AP within the service range corresponding to the current business, this only AP is enabled and an association relationship is established with the current business.

[0064] In some embodiments, the method further comprises: Divide all businesses into multiple business groups according to the types of communication technologies; Sort the services in each service group in ascending order according to one or more of the following information: The number of candidate APs for the service; the candidate APs refer to APs that can be used by the service; The sum of the service transmission demands in the overlapping service areas of the APs.

[0065] Specifically, if the number of APs within the service range corresponding to the current service is not 1, that is, there are multiple selectable APs, the services are first sorted to obtain an ordered set of services, and then the APs associated with the services are determined in sequence.

[0066] Specifically, all services are first divided into multiple service groups according to the category of communication technology, that is, the services in a service group use the same communication technology, and then the services in each service group are sorted in ascending order according to the following rules: the number of optional APs for the service, and / or the sum of the service transmission demands in the overlapping service areas of the APs.

[0067] For example, all services are divided into K service groups according to the category of communication technology, which are , , …, , sort the services in each service group in ascending order according to the number of optional APs for the services and / or the sum of the service transmission requirements in the overlapping service areas of the APs, to obtain the final K ordered service groups.

[0068] In some embodiments, determining the AP that needs to be enabled within the current service range based on the communication power consumption includes: Sort unactivated APs within the service range corresponding to the current service in descending order according to the number of activated communication technologies to obtain a second AP set; Determining whether the communication power consumption decreases after the current AP in the second AP set is turned on; In a case where the communication power consumption decreases after the current AP is turned on, it is determined to enable the current AP.

[0069] Specifically, the enabled APs within the service scope corresponding to the current service are sorted in ascending order according to the remaining amount of communication technology resources corresponding to the service to obtain an ordered AP set, namely the first AP set; and the unenabled APs within the service scope corresponding to the current service are sorted in descending order according to the number of enabled communication technologies to obtain an ordered AP set, namely the second AP set.

[0070] Determine whether the communication power consumption decreases after the new AP (i.e., the current AP in the second AP set) is turned on. If the communication power consumption decreases after the current AP is turned on, determine that the current AP in the second AP set can be enabled and update the first AP set; if the communication power consumption does not decrease after the current AP is turned on, do not enable the current AP.

[0071] Optionally, whether the communication power consumption decreases after the current AP in the second AP set is turned on may be determined by the following inequality:

[0072] In the formula, It indicates the i-th type of AP, which belongs to the first AP set; Indicates the first AP set; express In cycle Total transmission power consumption within ; represents the jth business set, Represents a collection of business sets; express In cycle Transmission power consumption within express In cycle Communication transmission delay within express The amount of data transfer, is the current AP in the second AP set, express of data transfer.

[0073] If the above formula is established, it means that the communication power consumption is reduced after the current AP in the second AP set is turned on. If the above formula is not established, it means that the communication power consumption is not reduced after the current AP in the second AP set is turned on.

[0074] The low-voltage side converged communication method provided by the embodiment of the present application, in a dense business scenario, in order to reduce the system energy consumption expenditure, needs to measure the relationship between the AP working energy consumption and the energy saving of the business terminal cluster, and determine whether the closed AP is turned on to provide services to the terminals in the overlapping service set area. The unenabled APs are sorted in descending order according to the number of enabled communication technologies to obtain a second AP set, and APs with a large number of enabled communication technologies are given priority. If the communication power consumption of the current AP in the second AP set decreases after being enabled, it indicates that enabling the AP can optimize the power consumption, so enabling the AP reduces the system energy consumption expenditure.

[0075] In some embodiments, determining the AP associated with the current service based on the data transmission volume of the enabled APs within the service range corresponding to the current service includes: Sort the enabled APs within the service range corresponding to the current service in ascending order according to the remaining amount of communication technology resources corresponding to the service to obtain a first AP set; Determine a first data transmission amount, a second data transmission amount, and a third data transmission amount; the first data transmission amount is the data transmission amount of the current AP in the first AP set; the second data transmission amount is the data transmission amount in the overlapping service area of ​​the current AP and the next AP in the first AP set; the third data transmission amount is the data transmission amount of the next AP; determining whether the sum of the first data transmission amount and the second data transmission amount is less than the third data transmission amount; The AP associated with the current service is determined based on the judgment result and the remaining resources of the AP.

[0076] Specifically, after sorting the enabled APs within the service scope corresponding to the current service in ascending order according to the remaining communication technology resources corresponding to the service to obtain the first AP set, determine the data transmission amount of the current AP in the first AP set, that is, the first data transmission amount, determine the data transmission amount in the overlapping service area between the current AP in the first AP set and the next AP, that is, the second data transmission amount, and determine the data transmission amount of the next AP in the first AP set, that is, the third data transmission amount.

[0077] Then, it is determined whether the sum of the first data transmission amount and the second data transmission amount is less than the third data transmission amount, and the AP associated with the current service is determined according to the determination result and the remaining resources of the AP.

[0078] In some embodiments, determining the AP associated with the current service based on the judgment result and the remaining resources of the AP includes: When the sum of the first data transmission amount and the second data transmission amount is less than the third data transmission amount and the remaining resources of the current AP meet the preset resource constraint, determining that the AP associated with the current service is the current AP; When the sum of the first data transmission amount and the second data transmission amount is greater than or equal to the third data transmission amount, and the remaining resources of the next AP in the first AP set meet the preset resource constraints, the AP associated with the current service is determined to be the next AP.

[0079] Specifically, if the sum of the first data transmission volume and the second data transmission volume is less than the third data transmission volume, the current AP is preliminarily selected, and it is further determined whether the remaining resources of the current AP meet the preset resource constraints. If so, the current AP is determined to be the AP associated with the current service.

[0080] If the sum of the first data transmission volume and the second data transmission volume is greater than or equal to the third data transmission volume, the next AP is preliminarily selected, and it is further determined whether the remaining resources of the next AP meet the preset resource constraints. If so, the next AP is determined to be the AP associated with the current service.

[0081] The low-voltage side converged communication method provided in the embodiment of the present application aims to solve the problem that the centralization phenomenon will lead to increased energy consumption in service transmission. It is necessary to select suitable APs for access to services in overlapping service sets. Specifically, the enabled APs within the service range corresponding to the current service can be sorted in ascending order according to the remaining communication technology resources. Then, based on the first data transmission volume, the second data transmission volume and the third data transmission volume, the AP associated with the current service is determined in combination with preset resource constraints, thereby ensuring high transmission quality, realizing rapid mapping connection between terminal services and APs, and improving transmission efficiency.

[0082] In some embodiments, the preset resource constraints include one or more of the following: The number of spectrum resource blocks allocated to the current AP is less than the number of spectrum resources that can be called by the communication technology used by the current AP; The communication resources allocated to the terminal meet the requirements of the current service.

[0083] Specifically, because spectrum resources and AP processing capabilities are limited, the communication carrying capacity of the AP is limited. Therefore, after initially selecting an AP as the AP associated with the current service, it is also necessary to determine whether the remaining resources of the AP meet the following preset resource constraints: Total number of spectrum resource blocks allocated to AP devices Less than the amount of spectrum resources that can be allocated ; and / or

[0084] The communication resources allocated to each terminal (total spectrum bandwidth size ) to meet their business requirements, ,in, Indicates the spectrum size of each resource block, Indicates the total number of allocated communication resource blocks.

[0085] The low-voltage side converged communication method for electric power provided in the embodiment of the present application ensures that the selected AP can successfully complete the transmission of business data and ensures the communication quality through preset resource constraints.

[0086] The information transmission methods provided in the above embodiments are further described below through specific examples: The embodiment of the present application proposes a heuristic-based fusion communication energy-saving scheduling algorithm (Heuristics-Fusion Communication Efficient Schedule, HFCES), which takes the specific communication service carried by the low-voltage side service terminal as the scheduling object. The overall idea is as follows: Figure 3 is a schematic diagram of a communication energy-saving scheduling scenario provided by the present invention, such as Figure 3 As shown, we first consider the AP situation that has to be enabled, that is, the AP whose mapping relationship cannot be selected and has to be enabled. Then we consider the selectable situation, that is, the service set in the overlapping service set area, and map all terminals in the overlapping area to appropriate APs in turn. In this process, we add the threshold judgment of terminal connection transfer and AP activation decision.

[0087] The algorithm pseudo code of the above-mentioned fusion communication energy-saving scheduling algorithm based on heuristic strategy is as follows:

[0088] The method for converged communication on the low-voltage side of the power grid provided in the embodiment of the present application aims to optimize the overall energy consumption of IoT communication on the low-voltage side. It utilizes the dense deployment of a large number of heterogeneous APs on the low-voltage side and the overlapping characteristics of service sets to allocate and schedule transmissions in different coverage areas from the perspective of device connection selection and AP activation. In addition, a communication access scheduling and power consumption optimization model is established to address the energy-saving issues of the communication access network under the converged communication architecture on the low-voltage side of the power grid, and a converged communication energy-saving scheduling algorithm (HFCES) based on a heuristic strategy is designed to quickly find terminal mapping connections and AP activation strategies, so as to minimize the overall transmission energy consumption while meeting business needs. After simulation experiments, it has been verified that the method proposed in the embodiment of the present application effectively reduces the overall transmission energy consumption while ensuring a high transmission quality.

[0089] In the actual experiment, simulation experiments were carried out based on the MATLAB platform, using a mixture of measured data and open source data sets. The measured data was collected from the operation of the two types of WiFi and Lora APs and multiple types of business terminals built in the Nanping Photovoltaic Park in Yuanzhou District, Guyuan City, Ningxia, and the AP-side network logs were continuously collected for 48 hours through automated scripts; the open source data set is the IOT TRAFFIC TRACES data set, which comes from a real scene with 28 devices built on campus by Professor Vijay Sivaraman's team at the University of New South Wales.

[0090] The comparison algorithm uses the Direct Greedy Algorithm (DGA) algorithm in the literature, which reduces system energy consumption by opening the minimum communication nodes; and the Dynamic Programming Algorithm (DPA) algorithm, which reduces the transmission energy consumption of business equipment by recording the global transmission strategy as a comparison.

[0091] By comparing the service transmission delay and system energy consumption of the HFCES algorithm, the DPA algorithm and the DGA algorithm, when the total number of data packets generated in the overlapping area and the independent area is small, the transmission delay of the DPA algorithm is lower than that of the HFCES algorithm and the DGA algorithm. The reason is that the DPA algorithm does not consider the impact of AP energy consumption on system energy consumption, so more APs can provide communication resources. On the other hand, since the present invention takes into account multiple types of large-bandwidth communication technologies, when the number of data packets is small, more spectrum resources can be allocated to a single transmission task. Therefore, when the number of data packets is small, the transmission delay changes little. As the number of data packets increases, the HFCES algorithm turns on new APs, increases the total amount of communication resources in the area, and thus reduces the transmission delay of the service terminal.
