[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] This embodiment provides a routing relay method, which can be specifically applied to collecting electricity consumption information in the comprehensive power market, such as Figure 1 As shown, the method is applied to a node that responds to a relay request, and the node that responds to the relay request is a node that has carrier communication capability and Bluetooth communication capability, and includes the following steps:

[0026] S101, when a relay request is received, determining whether the number of times the relay request is received within a preset time meets a preset requirement; if the preset requirement is met, executing S102;

[0027] Exemplarily, the carrier communication capability of the node may indicate that the node is capable of low-voltage power line high-speed carrier communication (HPLC), and the Bluetooth communication capability of the node may indicate that the node has a low-power Bluetooth BLE point-to-point relay connection function. The preset time may be 5 minutes, and the preset requirement may be that the same relay request is received more than twice within the preset time. The method for determining the number of relay requests received within the preset time may be that when a relay request is received, first determine whether the same request address has issued the same request within the preset time, and when the same request address has issued the request within the preset time, then determine whether the number of times the request is initiated within the preset time exceeds the preset number. This embodiment does not limit the preset time length and the preset requirement, and those skilled in the art can determine as needed.

[0028] S102, connecting via Bluetooth communication capability, and executing a relay task corresponding to the relay request.

[0029] Exemplarily, when the preset requirements are met, the connection is made through the Bluetooth communication capability, and the way to perform the relay task corresponding to the relay request can be: first, according to the Bluetooth communication capability of the current node, a point-to-point link connection is made with the node that initiates the relay request. The way to make the point-to-point link connection can be to start the low-power Bluetooth BLE point-to-point relay connection function through Bluetooth. Then, using the carrier communication capability of the current node, a connection request based on low-voltage power line high-speed carrier communication technology is initiated to the target address in the relay request, a relay communication link is established, and the corresponding data is transmitted according to the transmission task in the relay request.

[0030] The routing relay method provided in this embodiment determines whether the preset requirements are met after receiving the relay request by the node that responds to the relay request (a node with carrier communication capability and Bluetooth communication capability). If the preset requirements are met, the relay connection is performed according to the Bluetooth communication capability to complete the relay task, thereby solving the defect that the carrier communication technology cannot communicate normally due to the complex and changeable power environment, and improving the reliability of communication.

[0031] As an optional implementation of this embodiment, when the preset requirements are met, the connection is made through the Bluetooth communication capability, and the relay task corresponding to the relay request is executed, including:

[0032] As an optional implementation of this embodiment, the routing relay method further includes:

[0033] When the number of relay requests received within the preset time does not meet the preset number, it is determined whether the current load rate is less than the first preset load threshold; when the load rate is less than the first preset load threshold, the relay task corresponding to the relay request is executed.

[0034] Exemplarily, a method for determining whether the current load state is less than a first preset load threshold may be to count the load rate of the current node, and compare the load rate with a pre-stored first preset load threshold. The first preset load threshold may be 60% of the maximum load rate that the current node can bear. The load rate may be determined in units of minutes, communication load rate = total duration of executing communication services / 60S*100%, wherein the executed communication services include executing other relay tasks or other communication services, such as data transmission services executed when multiple devices are connected, etc. When the load rate is less than the first preset load threshold, the relay task corresponding to the relay request is executed. This embodiment does not limit the size of the first preset load threshold, and those skilled in the art may determine it as needed.

[0035] As an optional implementation of this embodiment, the routing relay method also includes: determining whether the load rate during the execution of the relay task exceeds a second preset load threshold; when the load rate of the relay node during the execution of the relay task exceeds the second preset load threshold, sending an early warning message to the node that initiates the relay request, and the early warning message is used to prompt the node that initiates the relay request to find a new node to respond to the relay request.

[0036] Exemplarily, the second preset load threshold represents that the load rate of the current node has basically reached the upper limit, and the specific numerical value may be 80% of the maximum load of the current node. This embodiment does not limit the value of the second preset load threshold, and those skilled in the art may determine it as needed. The method for judging whether the load rate in the process of executing the relay task exceeds the second preset load threshold may be: first, the load of the current node in the process of executing the relay task is monitored to obtain the communication data of the node, and then, according to the communication data of the node, it is judged whether the load rate in the process of executing the relay task exceeds the second preset load threshold. When the load rate of the relay node exceeds the second preset load threshold during the execution of the relay task, an early warning message is sent to the node that initiates the relay request to prompt the node that initiates the relay request, so as to facilitate the node that initiates the relay request to find a new node and form a new communication link to reduce the communication pressure of the current link.

[0037] As an optional implementation of this embodiment, the Bluetooth communication capabilities possessed by the relay node that receives the relay request include networking communication capabilities and point-to-point communication capabilities. The method also includes: when receiving information indicating that there is no new link sent by the node that initiates the relay request, reducing the networking communication parameters; when the networking communication parameters are reduced to a preset value, sending a warning.

[0038] Exemplarily, the networking communication capability indicates that the node has mesh Bluetooth networking function, and the Bluetooth sensor devices under the mesh Bluetooth sensor network can connect with other Bluetooth smart devices to form a network. Mesh Bluetooth is a networking mode based on flooding broadcast. Bluetooth nodes with the same configuration parameters can automatically form a mesh network. The broadcast signal works under three broadcast channels. In the mesh network, lightweight sensor data or smart device data within 11 bytes are transmitted each time. The point-to-point communication capability indicates that the node has a low-power Bluetooth BLE protocol working mode. The BLE protocol is a point-to-point connection protocol with a communication relay function.

[0039] When information indicating that there is no new link is received from the node that initiated the relay request, in order to ensure the priority of executing the relay task, the networking communication parameters are reduced. The networking communication parameters can be reduced by reducing the processing frequency of communication services in the mesh sensing networking mode. This embodiment does not limit the method of reducing the networking communication parameters, and technical personnel in this field can determine it as needed.

[0040] When the networking communication parameter is reduced to a preset value, a warning is sent, wherein the preset value may be 0, that is, when the processing frequency of the communication service in the mesh sensing networking mode is reduced to 0, a warning is sent. The warning may be sent to the node that initiates the relay request, or may be sent to the HPLC network coordination terminal to prompt network optimization and increase of communication nodes with relay capabilities.

[0041] The routing relay method provided in this embodiment is that the Bluetooth communication capabilities possessed by the relay node that receives the relay request include networking communication capabilities and point-to-point communication capabilities, thereby ensuring that each relay node can complete the networking function in addition to completing the relay task. The networking function can allow larger-scale node devices to access the network when performing applications such as wireless sensor networks and building automation networks, and perform reliable and secure transmission, and supports the access of smart devices, thereby improving the scalability of intelligent functions.

[0042] This embodiment provides a routing relay method, which is applied to a node that initiates a relay request, wherein the node that initiates the relay request is a node that has carrier communication capability and Bluetooth communication capability, and includes the following steps:

[0043] When the carrier communication link with the target communication node is blocked, the connectable communication nodes within the first target range are scanned through the Bluetooth communication capability, and the first target communication node among the connectable communication nodes is used as a relay node and a relay request is initiated to the relay node.

[0044] Exemplarily, the first target range can be determined by the connectable range of different Bluetooth modes themselves, and in this embodiment, it can be the connectable range in the low-power Bluetooth BLE point-to-point mode. When the carrier communication link between the node that initiates the relay request and the target communication node is not connected, the connectable communication nodes within the first target range are scanned by Bluetooth. If there are multiple connectable communication nodes, the first target communication node can be determined according to the signal strength, for example, the communication node with the strongest signal is selected as the first target communication node; it can also be determined according to the current load rate of multiple connectable communication nodes, for example, the communication node with the lowest current load rate among multiple connectable communication nodes is selected as the first target communication node. This embodiment does not limit the method of selecting the first target communication node, and those skilled in the art can determine it as needed. When the first target communication node is determined, a relay request is initiated to the node so that the node performs the corresponding relay task.

[0045] The routing relay method provided in this embodiment is that when the communication link is blocked, the node that initiates the relay request initiates the relay request through the Bluetooth function to establish a relay link, thereby solving the defect that the carrier communication technology cannot communicate normally due to the complex and changeable power environment, and improving the reliability of communication.

[0046] As an optional implementation of this embodiment, the routing relay method further includes:

[0047] First, when receiving the warning information sent by the first target communication node, scanning the communication nodes within the second target range, and initiating a relay request to the second target communication node, the warning information indicates that the load rate of the first target communication node performing the relay task is higher than the preset load rate;

[0048] Exemplarily, the second target range can be determined by the connectable range of different Bluetooth modes themselves, and in this embodiment, it can be the connectable range in the low-power Bluetooth BLE point-to-point mode. When the warning information sent by the first target communication node is received, it means that the load rate of the first target communication node is too high, higher than the preset load rate, and it is necessary to find other relay links to collaboratively complete the relay task. At this time, the communication nodes within the second target range are scanned, and a relay request is initiated to the second target communication node, wherein the preset load rate can be 80% of the current node's maximum load. The specific method of selecting the second target communication node is the same as the method of selecting the first target communication node, which will not be repeated here.

[0049] Secondly, when a relay link is formed with the second target communication node, the relay task is allocated to the first target communication node and the second target communication node.

[0050] Exemplarily, the relay task can be allocated to the first target communication node and the second target communication node by an equal distribution, or can be determined according to the current load rate of the first target communication node and the second target communication node. The higher the load rate, the fewer relay tasks are allocated. This embodiment does not limit the manner in which the relay task is allocated to the first target communication node and the second target communication node, and those skilled in the art can determine it as needed. Allocating the relay task to the two communication nodes improves the reliability of executing the relay task.

[0051] As an optional implementation of this embodiment, the routing relay method further includes:

[0052] First, receiving the load rate of the first target communication node and the load rate of the second target communication node; when the load rate of the first target communication node is lower than the third preset load threshold and the load rate of the second target communication node is lower than the fourth preset load threshold, determining whether the total load rate formed by executing the relay task is lower than the fifth preset load threshold;

[0053] Exemplarily, the third preset load threshold and the fourth preset load threshold may be 40% of the current node's maximum load, indicating that there is a lot of redundancy in the current node load, and the fifth preset load threshold may be 60% of the current node's maximum load rate, indicating that the relay task can be completed normally through one communication node. The total load rate formed by executing the relay task can be obtained by adding the load rate of the first target communication node and the load rate of the second target communication node.

[0054] When the first target communication node and the second target communication node are both performing relay tasks, the node that initiates the relay request will receive the load rate data of the first target communication node and the second target communication node, and adjust the task allocation according to the load rate data. When the load rate of the first target communication node is lower than the third preset load threshold and the load rate of the second target communication node is lower than the fourth preset load threshold, it indicates that there is a lot of redundancy when the first target communication node and the second target communication node perform relay tasks. At this time, it is determined whether the total load rate formed by the relay task is lower than the fifth preset load threshold. If it is lower than the fifth preset load threshold, the characterization can be completed by any one of the first target communication node and the second target communication node alone.

[0055] First, when the total load rate formed by executing the relay task is lower than the fifth preset load threshold, the relay link formed by connecting with the first target communication node or the relay link formed by connecting with the second target communication node is interrupted according to the target condition.

[0056] Exemplarily, the method for determining whether to interrupt the relay link formed by the connection of the first target communication node or the relay link formed by the connection of the second target communication node may be a random interruption, or an interruption according to the signal strength of the link connection, such as interrupting a link with a poor signal; it may also be determined based on the load rate of the communication node, such as interrupting a relay link with a higher current load rate. This embodiment does not limit the method for determining whether to interrupt the relay link, and those skilled in the art may determine it as needed.
