[0036] In an embodiment of the present application, the control unit is specifically configured to: obtain a message to be sent. If the current network state meets the first preset requirement, select an idle communication module with the highest communication rate from the at least one communication module, and use the idle communication module with the highest communication rate as the first The communication module calls the first communication module to send the message to be sent to the multi-mode communication device at the opposite end.

[0037] If the current network state does not satisfy the first preset requirement, then select n idle communication modules from the at least one communication module according to the order of communication rate from high to low, and select the n idle communication modules Each communication module in serves as the first communication module, adds a check mark to the message to be sent, and calls each first communication module to separately send the check mark to the multi-mode communication device at the opposite end to be sent Packet; where n is a positive integer greater than or equal to 2, the check mark is used by the multi-mode communication device at the opposite end to compare whether each received message with the same check mark added is the same.

[0038] In the embodiment of the present application, after acquiring the message to be sent, if the current network state meets the first preset requirement, the idle communication with the highest communication rate is selected from the at least one communication module As the first communication module, the module calls the first communication module to send the message to be sent to the multi-mode communication device at the opposite end. In addition, the control unit can also select other idle communication modules to send other messages to be sent, so as to send multiple messages through multiple communication modules in a good network state, thereby improving the network transmission rate and message transmission rate.

[0039] If the current network state does not meet the first preset requirement, the control unit selects n idle communication modules from the at least one communication module according to the order of communication rate from high to low, and selects n idle communication modules. Each communication module in the communication module serves as the first communication module, adds a check mark to the message to be sent, and calls each first communication module to send the added check mark to the multi-mode communication device at the opposite end respectively Messages to be sent. n is a positive integer greater than or equal to 2, the check mark is used by the multi-mode communication device at the opposite end to compare whether the received messages with the same check mark are the same, It can be seen that in a bad state under the network state, the reliability of the network transmission can be improved by selecting multiple communication modules to send messages.

[0040] In an embodiment of the present application, the network state includes a network rate, the network state meets the first preset requirement, which may be, the network rate is greater than a set rate threshold, and the network state does not meet the first preset requirement, which may be, the network The rate is not greater than the set rate threshold.

[0041] In an embodiment of the present application, the control unit is further specifically configured to: receive the message sent by the connected concentrator or electricity meter, and determine whether the length of the received message is greater than the length threshold; if so, the received The message is split and encoded to obtain the message to be sent, otherwise, the received message is encoded to obtain the message to be sent.

[0042] In the embodiment of the present application, a length threshold may be preset, if the length of the packet is greater than the length threshold, the packet is split, and the split packet is encoded to obtain the packet to be sent If the length of the message is not greater than the length threshold, the message is directly encoded to obtain the message to be sent. Among them, the purpose of encoding the message may be to encode the message into a transmittable format. The length of the message can be expressed by the number of bytes occupied by the message.

[0043] FIG. 4 is a schematic flowchart of a message sent by a multi-mode communication device according to an embodiment of the present application. As shown in FIG. 4, the process includes the following steps.

[0044] Step 402: Receive a message sent by a connected concentrator or electricity meter.

[0045] Step 404: Determine whether the length of the received message is greater than a length threshold; if so, execute Go to step 406, split into multiple messages, and perform 408; if not, perform step 408, to encode the message.

[0046] Step 410: Add the encoded message to the queue of messages to be sent.

[0047] Step 412: Take out a message to be sent.

[0048] Step 414: Determine whether the current network shape meets the first preset requirement.

[0049] Step 416: From the above-mentioned at least one communication module, according to the order of the communication rate from high to low, select n idle communication modules as the first communication module.

[0050] Step 418: Add a check mark to the message to be sent, and perform step 422.

[0051] Step 420: From the at least one communication module, select an idle communication module with the highest communication rate as the first communication module.

[0052] Step 422: Call the first communication module to send a message.

[0053] In an embodiment of the present application, the control unit is further specifically configured to: after receiving the message sent by the opposite-end multimode communication device, determine whether the received message carries a check mark; if not, then Determine whether the message is successfully received, otherwise, obtain the message carrying the same check mark from other received messages, and compare whether the received message and the obtained message are the same. If they are the same, determine the message The message reception is successful. If they are different, it is determined that the message reception failed.

[0054] In the embodiment of the present application, after receiving the message sent by the multi-mode communication device at the opposite end, the control unit determines whether the received message carries a check mark. If not, it means that the message is in If it is sent under good network conditions, it is determined that the message was successfully received. If the message carries a check mark, It means that this message was sent under the condition that the network status is not good, and the message carrying the same check mark will be obtained from other received messages, and the received message will be compared with the obtained Whether the described messages are the same; if they are the same, it is determined that the message is successfully received; if they are different, it is determined that the message is received unsuccessfully.

[0055] Among them, when the network state is not good, the multi-mode communication device will send multiple times through multiple first communication modules when sending a message, and each sent message carries a check mark, so here If the received message carries a check mark, then obtain the message carrying the same check mark from other received messages, and compare whether the received message and the obtained message are the same , If it is the same, it means that the complete message was received every time when the message is received multiple times, so it is determined that the message is successfully received. If it is different, it means that the received message is different each time, or that the message is received data Incomplete, so there is a case where the message reception is incorrect, and it is determined that the message reception has failed.

[0056] In an embodiment of the present application, the control unit is further configured to: after determining that the message is successfully received, check whether the received message is a fragmented message; if it is a fragmented message, determine the location of the fragmented message Whether other associated fragmented messages have been successfully received, if successful, the fragmented message and other fragmented messages associated with the fragmented message are combined and decoded; if it is not a fragmented message, the received The received message is decoded.

[0057] In this embodiment, after determining that the message is successfully received, the control unit checks whether the received message is a fragmented message; if it is a fragmented message, it determines the other fragmented messages associated with the fragmented message Whether the packets have been received successfully, if successful, the fragmented message and other fragmented messages associated with the fragmented message are merged, and the combined message is decoded; if it is not a fragmented message, then Directly received To decode the message.

[0058] In this embodiment, after splitting the packet, the control unit may digitally label each fragmented packet obtained by splitting, for example, the labeling form is "packet identifier + fragmented packet sequence number + The total number of fragments." After the control unit receives the packet, if the packet carries a digital label, the control unit determines that the packet is a fragmented packet, and can search for the fragmented packet in the received packet according to the digital label The message belongs to other fragmented messages of the same complete message, so as to determine whether all other fragmented messages associated with the fragmented message have been successfully received, if successful, the fragmented message and the fragmented message The other fragmented messages associated with the text are combined to obtain a complete message, and the complete message is decoded. If the received message does not have a digital label, it means that the message is not a fragmented message, so the control unit decodes the message directly.

[0059] FIG. 5 is a schematic flowchart of a message received by a multi-mode communication device according to an embodiment of the present application. As shown in FIG. 5, the procedure includes the following steps.

[0060] Step 502: Receive a message and add it to the received message queue.

[0061] Step 504: Determine whether the received message carries a check mark.

[0062] If yes, go to step 506. If not, go to step 514.

[0063] Step 506: Obtain a message carrying the same check mark from other received messages.

[0064] Step 508: Compare whether the received message and the obtained message are the same.

[0065] If the same, go to step 512, if different, go to step 510.

[0066] Step 510: Delete the received message and the obtained message, and feed back the reception failure. [0067] Step 512: Delete the acquired message, and delete the check mark in the received message.

[0068] Step 514: Determine that the message is successfully received.

[0069] Step 516: Check whether the received message is a fragmented message.

[0070] If yes, go to step 518, if not, go to step 522.

[0071] Step 518: Determine whether other fragmented messages associated with the received fragmented message have been successfully received.

[0072] If successful, go to step 520, otherwise, end the process.

[0073] Step 520: Combine fragmented messages to obtain a complete message.

[0074] Step 522: Decode the message.

[0075] In an embodiment of the present application, the control unit is further configured to: call the at least one communication module described above, send a network status detection instruction to the multi-mode communication device at the opposite end; call at least one communication module mentioned above, and receive the The response signal fed back by the multi-mode communication device according to the network state detection instruction; according to the response signal, determine the network status information with the opposite-end multi-mode communication device.

[0076] Specifically, the network state information includes the network rate and whether the network is available. In one case, the control unit calls each communication module, sends a network status detection instruction to the same communication module at the opposite end through the communication module, and receives a response signal returned by the same communication module at the opposite end, and the control unit detects according to the sent network status The time of the command and the time of receiving the response signal determine whether the communication rate and communication between this kind of communication module and the same kind of communication module at the opposite end are available. If the control unit does not receive a response after the sent network status detection instruction times out, it is determined that the communication module is not available at the opposite end The same kind of communication module. If a response to one or more peer communication modules is received after the network status detection instruction is issued, it is determined that the communication module has the same kind of communication module available at the peer, and the communication rate corresponding to each response is recorded.

[0077] In another case, the control unit determines the communication frequency band to be detected, calls the communication module working in the communication frequency band to send a network state detection instruction to the communication module working in the same communication frequency band of the opposite end, and receives the communication module of the opposite end For the returned response signal, the control unit determines whether the communication rate and communication between the communication module and the communication module at the opposite end are available in the communication frequency band according to the time of sending the network state detection instruction and the time of receiving the response signal.

[0078] In this embodiment, the control unit detects the network status in real time by sending a network status detection instruction, and determines the network status information with the peer multi-mode communication device according to the response signal received from the peer control unit, thereby The network communication status can be updated in real time.

[0079] In an example of an embodiment of the present application, the control unit is further configured to determine the target task priority threshold corresponding to the current network rate according to the current network rate and the preset task priority threshold corresponding to each network rate range; Select the task whose task priority is higher than the target task priority threshold in the task list, and transfer the selected task to the connected concentrator or electricity meter.

[0080] In this embodiment, the control unit determines the target task priority threshold corresponding to the current network rate according to the current network rate and preset task priority thresholds corresponding to each network rate range; and selects the task in the task list Tasks with a priority higher than the priority threshold of the target task will transfer the selected tasks to the connected concentrator or meter. [0081] In this embodiment, the control unit sets different network conditions corresponding to different task priority thresholds, so that the electricity meter and the concentrator can preferentially execute high-priority tasks according to different network conditions, thereby improving the efficiency of task processing.

[0082] Table 1 is a schematic table of different network condition levels corresponding to different task priority thresholds, and the network rate range can be set to three levels of excellent, good, and poor, wherein the network rates corresponding to the three levels of excellent, good, and poor are respectively The range is: above 100Mb/s (inclusive), 50Mb/s (inclusive)-100Mb/s, below 50Mb/s, set the priority of the task from high to low according to the importance of each task is 1, 2, 3, 4, 5, 6...n, when the network status is excellent, the corresponding task priority threshold is 0, which means that all tasks can be executed; when the network status is good, the corresponding The task priority threshold is 3, which means that the tasks after the task priority 3 are cancelled, and the tasks before the task 3 are executed preferentially; when the network condition is poor, the corresponding task priority threshold is 6, which means that the task priority is canceled For tasks after 6, priority is given to tasks before task 6.
