Description

Technical Field

[0001] This application relates to the field of smart grid technology, and more specifically, to a method, system, and terminal for collecting electricity consumption information based on 5G and Mesh networking. Background Technology

[0002] With the rapid development of smart grids, higher demands are placed on the real-time performance, completeness, and reliability of electricity consumption information collection. Currently, electricity consumption information collection systems mainly adopt the following communication methods: Power line carrier communication: This utilizes existing power lines for data transmission, eliminating the need for rewiring. However, its signal is susceptible to grid load and interference, resulting in poor stability and low communication success rate in complex grid environments. Low-power wireless communication: This offers flexible deployment and lower cost, but its transmission distance is short and its diffraction capability is poor. In the presence of walls, buildings, or other obstructions (such as in underground substations, densely populated urban areas, and remote rural households), signal blind spots are easily created, leading to numerous terminal device disconnections and data collection failures. Pure 5G communication: This offers advantages such as high bandwidth, low latency, and massive connectivity. However, for a large number of smart meter terminals, directly embedding a 5G communication module in each meter would lead to a sharp increase in hardware costs and power consumption, making large-scale commercial deployment difficult. Furthermore, in areas with weak signal coverage (such as basements), a single 5G terminal still cannot work effectively.

[0003] It is evident that using existing communication methods still results in coverage blind spots and low communication reliability in electricity information collection. Summary of the Invention

[0004] The purpose of this application is to address the shortcomings of the prior art by providing a method, system, and terminal for collecting electricity consumption information based on 5G and Mesh networking, so as to solve the problems of coverage blind spots and low communication reliability in the existing electricity consumption information collection.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows: In a first aspect, one embodiment of this application provides a method for collecting electricity consumption information based on 5G and Mesh networking, applied to an electricity consumption information collection system. The electricity consumption information collection system includes: a service data platform, a 5G-Mesh hybrid gateway, at least one Mesh relay node, and at least one intelligent collection terminal. The Mesh relay node is deployed in the target collection area. Both the intelligent collection terminal and the Mesh relay node integrate a wireless Mesh module. Each intelligent collection terminal accesses the 5G-Mesh hybrid gateway through the Mesh relay node. The 5G-Mesh hybrid gateway is communicatively connected to the service data platform. The method includes: After being powered on, the intelligent acquisition terminal automatically scans through the wireless Mesh module to connect to the current optimal target Mesh relay node. After acquiring the power consumption data to be transmitted, the intelligent acquisition terminal calculates and obtains the optimal path to the 5G-Mesh hybrid gateway according to the optimal path algorithm. The optimal path includes at least one Mesh relay node, including the target relay node. The intelligent data acquisition terminal sends the power consumption data to be transmitted to the next hop Mesh relay node according to the optimal path.

[0006] Optionally, after powering on, the intelligent acquisition terminal automatically scans via a wireless mesh module to connect to the current optimal target mesh relay node, including: After the intelligent acquisition terminal and the Mesh relay node are powered on, the intelligent acquisition terminal automatically scans and obtains the communication parameters of each Mesh relay node within the scanning range. The communication parameters include: signal strength parameters, link bandwidth parameters, and hop count to the 5G-Mesh hybrid gateway. The intelligent acquisition terminal selects the optimal target Mesh relay node based on the communication parameters, connects to the target Mesh relay node as the parent node, forms a Mesh network, and stores and records the dynamic routing information of the Mesh network.

The intelligent acquisition terminal selects and determines the optimal path to the 5G-Mesh hybrid gateway from the transmission path based on the optimal path algorithm and the communication parameters.

[0008] Optionally, the intelligent acquisition terminal selects and determines the optimal path to the 5G-Mesh hybrid gateway in the transmission path based on the optimal path algorithm and the communication parameters, including: The intelligent acquisition terminal determines the weights of each communication parameter based on the current transmission scenario; The intelligent acquisition terminal selects and determines the optimal path to the 5G-Mesh hybrid gateway from the transmission path by using the optimal path algorithm according to the weights corresponding to each communication parameter.

[0009] Optionally, the intelligent data acquisition terminal sends the power consumption data to be transmitted to the next-hop Mesh relay node according to the optimal path, including: The intelligent data acquisition terminal encapsulates the power consumption data to be transmitted and obtains the encapsulated power consumption data. The encapsulated power consumption data includes: path information of the optimal path, which is used to indicate the address and node order of each node in the optimal path. The intelligent data acquisition terminal sends the encapsulated power consumption data to the next hop Mesh relay node according to the optimal path. Each hop Mesh relay node, after receiving the encapsulated power consumption data, first decapsulates it to obtain the path information, and then sends the encapsulated power consumption data to the next hop Mesh relay node according to the path information.

[0010] Optionally, the method further includes: The intelligent acquisition terminal periodically detects the link quality between itself and its parent node and neighboring nodes; The intelligent acquisition terminal determines, based on the link quality, whether the current link quality with the problem node is lower than a preset threshold or whether the current link is disconnected. If the current link quality is lower than a preset threshold or the current link is disconnected, the intelligent acquisition terminal triggers path rediscovery, rescans to determine a new node to replace the problematic node, and establishes a connection with the new node.

[0011] Optionally, the link quality includes at least one or a combination of the following: packet loss rate, moving average of received signal strength, link symmetry index, and node reachability.

[0012] Optionally, the method further includes: The intelligent data acquisition terminal determines whether to send the power consumption data to be transmitted in real time or periodically, based on the importance level of the power consumption data to be transmitted. The intelligent data acquisition terminal sends the power consumption data to be transmitted to the next-hop Mesh relay node according to the optimal path, including: If the power consumption data to be transmitted is periodically sent, the intelligent acquisition terminal will package the multiple power consumption data to be transmitted acquired in this period, and send the packaged multiple power consumption data to be transmitted to the next hop Mesh relay node according to the optimal path.

[0013] Secondly, another embodiment of this application provides an electrical information acquisition system, comprising: a service data platform, a 5G-Mesh hybrid gateway, at least one Mesh relay node, and at least one intelligent acquisition terminal; wherein, the Mesh relay node is deployed in the target acquisition area, and both the intelligent acquisition terminal and the Mesh relay node integrate a wireless Mesh module, each of the intelligent acquisition terminals accessing the 5G-Mesh hybrid gateway through the Mesh relay node, and the 5G-Mesh hybrid gateway communicating with the service data platform; wherein...

[0014] Thirdly, another embodiment of this application provides an intelligent data acquisition terminal, including: a processor and a memory, wherein the memory stores machine-readable instructions executable by the processor, and when the intelligent data acquisition terminal is running, the processor executes the machine-readable instructions to perform the steps of any of the methods described in the first aspect above.

[0015] The beneficial effects of this application are: After powering on, the intelligent data collection terminal automatically scans via the wireless mesh module to access the optimal target mesh relay node. After acquiring the power consumption data to be transmitted, it calculates the optimal path to the 5G-Mesh hybrid gateway based on the optimal path algorithm. According to the optimal path, it sends the power consumption data to the next-hop mesh relay node. This eliminates the need for a single intelligent data collection terminal to establish a direct connection with the remote gateway. Instead, it can transmit signals one by one through multiple relays. Mesh relay nodes are low-cost and numerous, enabling extensive and deep coverage. This effectively solves the signal blind spot problem in power consumption information collection, improves communication reliability, and reduces system cost and power consumption.

The components of the embodiments of this application described and illustrated herein can typically be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0021] With the rapid development of smart grids, higher requirements are placed on the real-time performance, completeness, and reliability of electricity consumption information collection. Given the relatively limited communication methods in existing smart grid technologies, blind spots in electricity consumption information collection and low communication reliability may still exist. This application proposes a new networking method and a corresponding new method for collecting electricity consumption information.

[0022] Figure 1 This is a schematic diagram of the structure of an electrical information acquisition system provided in an embodiment of this application, as shown below. Figure 1 As shown, the electrical information acquisition system provided in this application embodiment includes: a business data platform 101, a 5G-Mesh hybrid gateway 102, at least one Mesh relay node 103, and at least one intelligent acquisition terminal 104.

[0023] Each Mesh relay node 103 is deployed in the target collection area. In specific power grid application scenarios, multiple power collection areas can be divided according to geographical location and other information. For example, a residential community is a target collection area. There is no restriction here. Each target collection area can have one or more Mesh relay nodes 103 and one or more smart collection terminals 104.

[0024] Both the intelligent data acquisition terminal 104 and the Mesh relay node 103 integrate a wireless Mesh module (such as a WIFI-Mesh module) to facilitate the establishment of a wireless connection.

[0025] Each intelligent data acquisition terminal 104 is connected to the 5G-Mesh hybrid gateway 102 through the Mesh relay node 103, and the 5G-Mesh hybrid gateway 102 is connected to the business data platform 101.

[0026] In this embodiment of the application, the intelligent data acquisition terminal 104 can transmit the collected power consumption data to the 5G-Mesh hybrid gateway 102 through one-hop or multi-hop Mesh relay nodes 103, and then the 5G-Mesh hybrid gateway 102 will finally report it to the service data platform 101.

[0027] The 5G-Mesh hybrid gateway 102 and the business data platform 101 are connected via a 5G network.

[0028] Taking the collection of electricity meter data in the basement of a residential community as an example, the 5G signal in the basement is weak, and low-power wireless signals cannot penetrate multiple floors. According to the deployment method of this application embodiment, a 5G-Mesh hybrid gateway can be deployed at a location with good ground signal (such as the roof of a building). In the stairwell from the ground to the basement, a Mesh relay node (with a built-in wireless Mesh function module) is deployed at intervals. Each smart data collection terminal in the basement (i.e., a smart meter) has a built-in wireless Mesh function module. Mesh relay nodes are low-cost and can be deployed in large numbers to achieve comprehensive coverage of blind spots.

[0029] The intelligent acquisition terminal 104 is used to automatically scan through the wireless Mesh module after power-on to access the current optimal target Mesh relay node; after acquiring the power consumption data to be transmitted, it calculates the optimal path to the 5G-Mesh hybrid gateway according to the optimal path algorithm, the optimal path including at least one Mesh relay node including the target relay node; and sends the power consumption data to be transmitted to the next hop Mesh relay node according to the optimal path.

[0030] In this embodiment, by connecting the intelligent acquisition terminal to the target Mesh relay node, a self-organizing network is formed, which can then obtain the optimal path to transmit electricity consumption data. This means that a single intelligent acquisition terminal no longer needs to establish a direct connection with the remote gateway, but can transmit the signal one by one through multi-hop relays. Moreover, Mesh relay nodes are low-cost and numerous, and can provide extensive and in-depth coverage, effectively solving the signal blind spot problem in electricity consumption information collection, improving communication reliability, and reducing system cost and power consumption.

[0031] Figure 2 This is a flowchart illustrating a method for collecting electricity consumption information based on 5G and Mesh networking, provided in an embodiment of this application. This method is applied to the aforementioned electricity consumption information collection system, such as... Figure 2 As shown, the method includes: S201. After powering on, the intelligent acquisition terminal automatically scans through the wireless Mesh module to connect to the current optimal target Mesh relay node.

[0032] It should be noted that after the electricity information collection system starts collecting data, the Mesh relay nodes, intelligent collection terminals, and 5G-Mesh hybrid gateways are all powered on.

[0033] After the intelligent data acquisition terminal is powered on, it automatically scans through the wireless Mesh module and can select the current last target Mesh relay node. Since a large number of Mesh relay nodes are deployed to cover blind spots, the target Mesh relay node that the intelligent data acquisition terminal connects to each time can be different. The weight of communication parameters to be considered when selecting the Mesh relay node to connect to varies depending on the scenario.

[0034] S202. After the intelligent acquisition terminal obtains the power consumption data to be transmitted, it calculates and obtains the optimal path to the 5G-Mesh hybrid gateway according to the optimal path algorithm.

[0035] The optimal path includes at least one Mesh relay node, including the target relay node.

[0036] Optionally, when selecting the optimal path, the intelligent data acquisition terminal should consider not only the number of hops through the nodes, but also the communication situation in the entire network.

[0037] S203. The intelligent data acquisition terminal sends the power consumption data to be transmitted to the next hop Mesh relay node according to the above optimal path.

[0038] The intelligent data acquisition terminal sends the power consumption data to be transmitted based on the address of the next-hop Mesh relay node in the optimal path. The power consumption data to be transmitted may carry the starting address, destination address, and addresses of the nodes along the route, which are not specifically restricted here.

[0039] In this embodiment, after the intelligent data acquisition terminal is powered on, it automatically scans through the wireless Mesh module to access the current optimal target Mesh relay node. After acquiring the power consumption data to be transmitted, it calculates the optimal path to the 5G-Mesh hybrid gateway according to the optimal path algorithm. Based on the above optimal path, it sends the power consumption data to be transmitted to the next hop Mesh relay node. This realizes that a single intelligent data acquisition terminal no longer needs to establish a direct connection with the remote gateway, but can transmit the signal one by one through multi-hop relays. Moreover, Mesh relay nodes are low-cost and numerous, and can provide extensive and in-depth coverage, effectively solving the signal blind spot problem in power consumption information collection, improving communication reliability, and reducing system cost and power consumption.

[0040] Optionally, after powering on, the aforementioned intelligent data acquisition terminal automatically scans via a wireless mesh module to connect to the current optimal target mesh relay node, which may include: After the intelligent acquisition terminal and the Mesh relay node are powered on, the intelligent acquisition terminal automatically scans and obtains the communication parameters of each Mesh relay node within the scanning range. Then, based on the communication parameters, it selects the current optimal target Mesh relay node, uses the target Mesh relay node as the parent node to connect, forms a Mesh network, and stores and records the dynamic routing information of the Mesh network.

[0041] The aforementioned communication parameters include: signal strength parameters, link bandwidth parameters, and hop count to the 5G-Mesh hybrid gateway. The signal strength parameter can be a Received Signal Strength Indicator (RSSI), and the link bandwidth parameter can be the available bandwidth of the link.

[0042] For different application scenarios, such as whether there is high-priority data transmission, urgent data transmission, and normal data transmission, different weights can be set for each communication parameter to evaluate each Mesh relay node and select the optimal target Mesh relay node as the parent node for access. Optionally, after selecting the parent node, an association request is sent to the parent node. Upon receiving the access response from the parent node, the connection to the Mesh network is confirmed, and the dynamic routing information of the Mesh network is stored for subsequent path selection. Specifically, the dynamic routing information of the Mesh network can be recorded in the form of network topology.

[0043] Based on the above embodiments, after the intelligent data acquisition terminal acquires the power consumption data to be transmitted, it calculates and obtains the optimal path to the 5G-Mesh hybrid gateway according to the optimal path algorithm, which may include: After acquiring the power consumption data to be transmitted, the intelligent acquisition terminal executes a dynamic routing discovery protocol based on the dynamic routing information of the Mesh network to detect and obtain at least one transmission path. Then, based on the optimal path algorithm and the aforementioned communication parameters, it selects and determines the optimal path to the 5G-Mesh hybrid gateway from the aforementioned transmission paths.

[0044] Optionally, before transmitting data, the intelligent acquisition terminal can obtain communication parameters through broadcasting. Specifically, the intelligent acquisition terminal can broadcast a routing request message, which includes source address, destination address, and path quality metric information, etc. By receiving the response data from the Mesh relay node based on the routing request message, the intelligent acquisition terminal can further obtain communication parameters and execute a dynamic route discovery protocol to obtain at least one potential transmission path.

[0045] If multiple transmission paths exist, then the optimal path to the 5G-Mesh hybrid gateway can be determined further based on the optimal path algorithm.

[0046] Optionally, the intelligent acquisition terminal, based on the optimal path algorithm and the aforementioned communication parameters, selects and determines the optimal path to the 5G-Mesh hybrid gateway from the aforementioned transmission paths, which may include: The intelligent acquisition terminal determines the weight of each communication parameter based on the current transmission scenario. Furthermore, based on the weight of each communication parameter, the intelligent acquisition terminal uses the optimal path algorithm to select and determine the optimal path to the 5G-Mesh hybrid gateway from the transmission path.

[0047] For example, if urgent data needs to be transmitted, the shortest path should be prioritized, with the hop count from the 5G-Mesh hybrid gateway having the highest weight, while also ensuring transmission speed and a relatively high weight for signal strength. For normal transmission, due to cost considerations, the weights of the hop count from the 5G-Mesh hybrid gateway and signal strength can be reduced, without specific restrictions here.

[0048] For example, the evaluation result of each transmission path = w1 × average signal strength parameter + w2 × (hop count of 1 / 5G-Mesh hybrid gateway) + w3 × minimum available bandwidth, where w1, w2, and w3 are the weight coefficients corresponding to the signal strength parameter, the hop count of the distance to the 5G-Mesh hybrid gateway, and the link bandwidth parameter, respectively. These weights are configured according to the needs of different application scenarios. In the specific implementation process, various combinations of weight coefficients corresponding to different scenarios can be pre-stored in the intelligent acquisition terminal, and different combinations of weight coefficients can be switched according to the power consumption data to be transmitted.

[0049] Figure 3 A flowchart illustrating another embodiment of the electricity consumption information collection method based on 5G and Mesh networking provided in this application is shown below. Figure 3 As shown, the aforementioned intelligent data acquisition terminal sends the power consumption data to be transmitted to the next-hop Mesh relay node according to the optimal path, including: S301. The intelligent data acquisition terminal encapsulates the above-mentioned power consumption data to be transmitted and obtains the encapsulated power consumption data.

[0050] The encapsulated power consumption data includes: path information of the optimal path, which is used to indicate the address and node order of each node in the optimal path.

[0051] S302. The intelligent data acquisition terminal sends the encapsulated power consumption data to the next hop Mesh relay node according to the above optimal path.

[0052] Each hop Mesh relay node receives the encapsulated power consumption data, first decapsulates it to obtain the path information, and then sends the encapsulated power consumption data to the next hop Mesh relay node according to the path information.

[0053] It should be noted that when the intelligent data acquisition terminal encapsulates the electricity consumption data to be transmitted, it encapsulates the source address information, the destination address information, and also encapsulates the addresses and order of the nodes along the optimal path. In this way, during the transmission process, after each hop Mesh relay node receives the encapsulated electricity consumption data, it first decapsulates it according to a pre-agreed method to obtain the path information, determines the next hop Mesh relay node based on the path information, recapsulates it, and sends the encapsulated electricity consumption data to the next hop Mesh relay node.

[0054] Figure 4 This is a flowchart illustrating a method for collecting electricity consumption information based on 5G and Mesh networking, provided in another embodiment of this application. In this embodiment, a network self-healing function is also provided. When a node in the network fails or the wireless environment deteriorates, the affected node can automatically and quickly rediscover and connect to a new node, establish a new transmission path, and thus ensure the communication reliability of the entire system.

[0055] like Figure 4 As shown, the above method also includes: S401, the intelligent data acquisition terminal periodically detects the link quality between the parent node and adjacent nodes.

[0056] The neighboring node here refers to the neighboring node that has established a network connection with the intelligent acquisition terminal. The intelligent acquisition terminal can periodically send probe requests to the parent node and neighboring nodes and receive responses from the corresponding nodes, thereby obtaining the link quality between the parent node and neighboring nodes.

[0057] Optionally, link quality includes at least one or a combination of the following: packet loss rate, moving average of received signal strength, link symmetry index, node reachability, etc.

[0058] It should be noted that the link quality parameters mentioned here can refer to the aforementioned communication parameters, or they can be the same as or more than the aforementioned communication parameters, taking into account a wider range of situations. There are no specific restrictions here.

[0059] S402. Based on the above link quality, the intelligent acquisition terminal determines whether the current link quality with the problem node is lower than a preset threshold or whether the current link is disconnected.

[0060] Among them, problem nodes refer to nodes whose link quality with the intelligent data acquisition terminal is lower than a preset threshold or has been disconnected.

[0061] S403. If the current link quality is lower than the preset threshold or the current link is disconnected, the intelligent acquisition terminal triggers path rediscovery, rescans to determine a new node to replace the aforementioned problematic node, and establishes a connection with the new node.

[0062] Specifically, if the intelligent acquisition terminal detects that the current link quality is lower than a preset threshold or the current link is disconnected, it can trigger path rediscovery by referring to the discovery process in the aforementioned embodiment, and rebroadcast to rescan and determine new nodes to replace the problematic nodes. That is, it selects nodes whose link quality meets the connection conditions, re-establishes the connection, and forms a new network to ensure communication reliability. It can also repair the network in a timely manner when a fault occurs without human intervention.

[0063] Furthermore, in order to reduce power consumption, in this embodiment of the application, the intelligent acquisition terminal determines whether to send the power consumption data to be transmitted in real time or periodically, based on the importance level of the power consumption data to be transmitted.

[0064] The electricity consumption data to be transmitted varies in importance depending on its type. For example, electricity consumption data from ordinary residential communities does not need to be transmitted immediately; it can be uploaded periodically, which also saves energy. In some industrial or emergency scenarios, the data is of high importance and needs to be transmitted in real time.

[0065] Accordingly, the intelligent data acquisition terminal sends the power consumption data to be transmitted to the next hop Mesh relay node according to the optimal path, which may include: if the power consumption data to be transmitted is sent periodically, the intelligent data acquisition terminal packages the multiple power consumption data to be transmitted acquired in this period, and sends the packaged multiple power consumption data to the next hop Mesh relay node according to the optimal path.

[0066] Specifically, since power consumption data is sent periodically, power consumption data to be transmitted may be received successively during the waiting period. The received power consumption data to be transmitted can be cached in order in the queue to be sent, and then packaged together and sent according to the preset period, which can save transmission resources.

[0067] Taking the collection of electricity meter data in the basement of a certain community as an example, this embodiment further illustrates that, using the method provided in this embodiment, after the system is powered on, the 5G-Mesh hybrid gateway accesses the Internet via 5G and declares itself as the Mesh root node.

[0068] Mesh relay node A in the stairwell detects the signal of the 5G-Mesh hybrid gateway and establishes a connection with it. Mesh relay node B detects the signal of Mesh relay node A (and, based on communication parameters, is superior to the 5G-Mesh hybrid gateway), and thus establishes a connection with Mesh relay node A. Smart acquisition terminal C in the basement detects the signal of Mesh relay node B (which is currently the best), and thus establishes a connection with Mesh relay node B. This forms a complete communication link: "Smart acquisition terminal C -> Mesh relay node B -> Mesh relay node A -> 5G-Mesh hybrid gateway -> 5G network -> service data platform". Using the method provided in this embodiment, the electricity consumption data acquired by smart acquisition terminal C can be transmitted to the service data platform through this communication link.

[0069] Correspondingly, the communication link can self-heal. For example, if Mesh relay node B loses power due to a fault, the intelligent acquisition terminal C detects that the link with Mesh relay node B is broken and rescans, which may then discover another currently optimal Mesh relay node D, establish a connection with Mesh relay node D, and form a new communication link. The whole process can be completed in full automation.

[0070] Based on the same inventive concept, this application also provides an electricity consumption information collection device based on 5G and Mesh networking, which corresponds to the electricity consumption information collection method based on 5G and Mesh networking. This device can be integrated into the intelligent collection terminal in the above system. Since the principle of the device in this application embodiment solves the problem is similar to the principle of the method executed by the intelligent collection terminal in the above method of this application embodiment, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.

[0071] Reference Figure 5 As shown, Figure 5 This is a schematic diagram of a power consumption information collection device based on 5G and Mesh networking, provided in an embodiment of this application. The device includes: an access module 501, a processing module 502, and a transmission module 503; wherein, The access module 501 is used to automatically scan through the wireless Mesh module after the intelligent acquisition terminal is powered on, so as to access the current optimal target Mesh relay node.

[0072] The processing module 502 is used to obtain the power consumption data to be transmitted, and then calculate the optimal path to the 5G-Mesh hybrid gateway according to the optimal path algorithm. The optimal path includes at least one Mesh relay node, including the target relay node.
