[0033] Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some of the embodiments of the present application, and the present application is not limited by the example embodiments described herein. Embodiment 1

[0034] As Figure 1As shown, the peripheral energy consumption data collection method based on HPLC and Bluetooth provided by the embodiment of the present application can include steps S100, S200 and S300.

[0035] In step S100, a bus topology based on HPLC and a Mesh network topology based on Bluetooth are established between the smart meter and the smart sockets within the jurisdiction of the smart meter, so that the smart meter is directly connected with the smart sockets by power lines or Bluetooth or is indirectly connected with the smart sockets by at least one other smart socket as a relay node.

[0036] Specifically, the HPLC high-speed power line carrier technology has been widely used in the construction of smart grids today, such as the application in concentrators, collectors, smart meters to achieve high-speed transmission of data, and the HPLC technology has also been widely used in the Internet of Things and smart homes, such as the application in smart sockets to enable smart sockets to realize various advanced functions such as real-time monitoring and remote control. HPLC power line carrier is prone to interference from high-power devices when solving the communication problem between the meter and the smart socket, resulting in communication failure. Bluetooth wireless communication is flexible, but due to high-frequency signals, short wavelength, weak diffraction ability, and poor wall communication effect, the communication ability between outdoor meters and indoor communication or indoor multi-room communication is weak. Therefore, it is necessary to establish a complementary communication network based on HPLC and Bluetooth to solve the communication problem between outdoor meters and indoor smart sockets. Therefore, it can be understood that a carrier communication module is installed in the smart meter and the smart sockets within the jurisdiction of the smart meter, so that a bus topology based on HPLC is established between the smart meter and the smart sockets within the jurisdiction of the smart meter. In the communication system of the established bus topology, each smart socket within the jurisdiction of the smart meter is directly connected with the smart meter by power lines. A Bluetooth communication module is installed in the smart meter and the smart sockets within the jurisdiction of the smart meter, and the Mesh network is formed by the Bluetooth communication module, and then a Mesh network topology based on Bluetooth is established between the smart meter and the smart sockets within the jurisdiction of the smart meter. In the communication system of the established Mesh network topology based on Bluetooth, each smart socket within the jurisdiction of the smart meter is directly connected with the smart meter or indirectly connected with the smart meter by at least one other smart socket as a relay node.

[0037] Preferably, the end-use energy collection system of the present application comprises an end-use energy user app, which is communicatively connected with the energy data collection center, and the information of the smart sockets within the jurisdiction of the smart meter is added by the end-use energy user through the app and uploaded to the energy data collection center, and then distributed by the energy data collection center to the corresponding smart meter through the concentrator, the smart meter stores the information of the smart sockets within the jurisdiction and adds it as a white list, and the networking request of the smart socket nodes outside the white list is rejected.

[0038] In step S200, the smart meter sends a message representing the detection of the communication state to the smart sockets within the jurisdiction through the HPLC and BLE dual channels, in response to which the smart sockets send a return message to the smart meter through the HPLC and BLE dual channels, and the smart meter formulates the hop count and transmission order of the data packet transmission of each smart socket node based on the return message of each smart socket node;

[0039] Specifically, the inventors found that in the process of Mesh networking communication between smart sockets, there are problems of large message propagation range, more forwarding times and repeated forwarding, which cause communication delay of the network, especially in the case of more smart socket nodes under the same energy user, which will seriously affect the response speed and stability of the system. In order to solve these technical problems, the inventors provide a processing method, that is, after the networking between the smart meter and the smart sockets within the jurisdiction of the smart meter is completed, the smart meter sends a message representing the detection of the communication state to the smart sockets within the jurisdiction through the HPLC and BLE dual channels to obtain the data transmission link with each smart socket node, and then formulates the hop count and transmission order of the data packet transmission of each smart socket node according to all the data transmission links with each smart socket node;

[0040] The specific steps of the smart meter obtaining the data transmission link with each smart socket node are as follows: Figure 2As shown, first, the smart meter sends a message representing the detection communication state to all smart sockets in the jurisdiction through the HPLC and BLE dual channels, the message representing the detection communication state is sent in the form of broadcast, and the smart socket node analyzes and verifies the message after receiving the message representing the detection communication state, wherein the message representing the detection communication state contains a preset check code, the smart socket node verifies the check code in the message, if the verification fails, it does not respond to eliminate the influence of interference signals on the security of the communication system, if the verification is passed, it returns a return message representing its own communication state to the smart meter through the HPLC and BLE dual channels, and at the same time, it forwards the message representing the detection communication state through the HPLC and BLE dual channels to other smart socket nodes to receive the message, wherein the return message representing its own communication state also contains a preset check code, since the direct or indirect communication connection between the smart socket node and the smart meter based on the Bluetooth Mesh network contains multiple communication links, the return message representing its own communication state is returned to the smart meter through multiple Bluetooth communication links, and after the smart meter receives the return message representing its own communication state of the same smart socket node through multiple Bluetooth links and HPLC links, it analyzes and verifies the message, if the verification is passed, it formulates the hop number and transmission order of each smart socket node data packet transmission according to all data transmission links with each smart socket node respectively;

[0041] The smart meter formulates the hop number and transmission order of each smart socket node data packet transmission based on the return message of each smart socket node, including:

[0042] The return message representing its own communication state of the smart socket is forwarded to the smart meter through the Bluetooth Mesh network, and the smart meter calculates the average number of data packet transmission hops as the hop number of a single smart socket node data packet transmission according to the transmission hop number of multiple return messages of the same smart socket node forwarded through the Bluetooth Mesh network, and the subsequent message transmission between the smart meter and each smart socket node is based on this hop number of data packet transmission, to prevent the infinite circulation of data packets in the communication network and cause delay and network congestion problems, affecting the stability and response speed of the system;

[0043] The smart meter sorts the hop counts of all smart socket node data packet transmissions in descending order, and the smart meter formulates the order of the transmission of instructions and data to the smart socket nodes according to the results of the descending order sorting of the hop counts of the smart socket node data packet transmissions. It can be understood that the greater the hop count of the data transmission between the smart meter and the smart socket via the Bluetooth Mesh network communication, the farther the distance between them. In order to meet the requirement that each smart socket node can respond to the same instruction of the smart meter in time, for example, the smart socket node far away from the smart meter needs to be given the collection instruction in priority when collecting energy data, so as to achieve that the return messages of different smart socket nodes can arrive at the same time and improve the response speed of the system.

[0044] Preferably, in order to solve the problem of repeated message forwarding, the smart socket node should have a message caching function. The smart socket node caches a first fixed-length message queue, for example, a message queue of 10-20 messages, which is not limited here. The message queue follows the first-in-first-out rule. The smart socket node judges whether the received message is a repeated message according to the message caching queue. The repeated message is not forwarded and responded to, which reduces the delay problem caused by repeated forwarding and further improves the response speed of the system.

[0045] Referring back to Figure 1 In step S300, the smart meter sends the message of collecting energy data to each smart socket node through the HPLC and BLE dual channels according to the hop count and transmission order of each smart socket node data packet transmission at a predetermined frequency. After receiving the answer message of collecting energy data of each smart socket node, the smart meter maintains and stores the energy data of each smart socket node, and reports to the energy data collection center through the concentrator.

[0046] Specifically, the inventors found that when collecting end use energy data through HPLC and Bluetooth, there are cases where two-way use energy data returned by the same smart socket node are inconsistent or only one-way use energy data is received. Based on the above problems, it is necessary to maintain the reliability of the collected use energy data to improve the credibility of the data. Therefore, the inventors propose a processing method, i.e. step S300, in which the smart meter sends a message collecting use energy data to each smart socket node through HPLC and BLE dual channels according to the number of hops and transmission sequence of the data packet transmission formulated by the smart meter to each smart socket node at a predetermined frequency. The message is sent in the form of unicast. The predetermined collection frequency can be collecting once every 15-20 minutes, which is not limited here. The smart socket node responds after receiving and parsing the message and verifying that it is passed. The smart socket node sends the end use energy data collected by itself to the smart meter through the dual communication channels. The smart meter performs reliability maintenance on the use energy data of each smart socket node after receiving and parsing the collected use energy data response message of each smart socket node and verifying that it is passed. The smart meter performs reliability maintenance on the use energy data of each smart socket node as shown in Figure 3 , specifically including:

[0047] When the smart meter receives the return message of the collected use energy data sent by the same smart socket node through HPLC and BLE dual channels, the smart meter compares and judges whether the two-way use energy data are consistent:

[0048] When they are consistent, store any one-way use energy data of the current smart socket node as the final use energy data of the current smart socket node;

[0049] When they are not consistent, the corresponding smart socket node is requested to collect use energy data again, and a one-time collection of use energy data is performed. The two-way use energy data are judged again after the collection of use energy data. If they are consistent, step (1) is performed. Otherwise, store the two-way use energy data and perform fault marking and data verification request marking. The use energy data collection center performs reliability verification on the two-way data according to the data verification request marking and historical data, selects the one-way data with high credibility as the final use energy data, and improves the credibility of the collected end use energy data;

[0050] When the smart meter only receives the return message of the collected energy data sent by the same smart socket node through the HPLC or BLE channel, the smart meter stores the energy data reported by the current smart socket node, and marks the communication channel that does not receive the return message as having a communication failure. If the same communication channel of the same smart socket node is marked as having a communication failure more than a predetermined threshold, it will be finally determined that a communication failure has occurred, avoiding misjudgment caused by communication failure after a few times of interference. The information of the smart socket node finally determined to have a communication failure is sent to the energy data collection center.

[0051] After receiving the return message of the collected energy data of all smart socket nodes within the jurisdiction, the smart meter uploads the collected end energy data to the energy data collection center through the concentrator, and uploads the information of all smart socket nodes marked as having a communication failure and finally determined to have a failure to the energy data collection center, so as to timely and reliably find the communication failure problem of the HPLC carrier module and the Bluetooth module of the smart socket device.

[0052] The energy data collection center downloads the collected end energy data to the end energy user app for display, so that the end energy user can conveniently view the energy data of each smart socket node under his house. The energy data collection center downloads the collected smart socket node communication failure information to the end energy user app for early warning display to remind the end energy user to handle it. Embodiment 2

[0053] Hereinafter, a kind of end energy data collection system based on HPLC and Bluetooth provided according to the embodiments of the present application will be described with reference to Figure 4 .

[0054] As Figure 4 shown, the system can include:

[0055] Smart meter, smart socket, concentrator, end energy user app and energy data collection center

[0056] The smart socket is installed with HPLC module and Bluetooth module, and is in communication connection with the smart meter, for collecting end energy data and responding to the instructions of the smart meter. The smart socket includes a message buffer module for realizing the message buffer function in the above embodiment 1.

[0057] The smart meter is installed with HPLC module and Bluetooth module, for sending the collected energy data instructions to the smart socket according to the predetermined frequency to collect end energy data, and for maintaining the reliability of the collected end energy data and uploading to the energy data collection center.

[0062] The specific functions and operations of each module in the above-mentioned HPLC and Bluetooth-based terminal energy consumption data collection system are described in detail in the above-mentioned embodiment 1, and therefore, the repeated description will be omitted here.

[0063] In summary, the HPLC and Bluetooth-based terminal energy consumption data collection system and method of the present application can control the propagation range of messages in the communication network by formulating the hop count and transmission sequence of the data packet transmission of each smart socket node and adding a message caching strategy in the smart socket node through the message returned by the smart socket indicating the communication state of the smart socket, thereby avoiding invalid transmission of messages and reducing transmission of repeated messages, optimizing the communication performance during Bluetooth Mesh networking communication, and improving the stability and response speed of the system. After the smart meter collects the terminal energy consumption data based on the Bluetooth Mesh networking communication optimization measure, the reliability of the collected terminal energy consumption data is maintained, which can improve the credibility of the collected terminal energy consumption data, and at the same time, the communication fault of the HPLC carrier module and the Bluetooth module of the smart socket device can be discovered early, and the fault information can be displayed for early warning at the terminal user to allow the user to handle it in time. At the same time, the terminal energy consumption user can remotely control the smart socket under his house through the system of the present application, so as to realize convenient and effective interaction between the power user and the power grid.
