Background
With the development of scientific technology, the application of high-speed carrier communication technology is becoming more and more extensive. In the prior art, a high-speed carrier communication technology of a centralized meter reading system divides a signal communication bandwidth into four different communication sub-frequency bands from 0.7MHz to 12MHz, and through additional auxiliary channel analysis equipment, the environment quality of a carrier communication channel can be analyzed according to the actual use environment, so that a proper communication frequency band is matched, and the communication frequency band of the whole distribution area is preset to improve the success rate of communication.
However, the power line communication channel condition is not constant, and may vary differently according to the power load condition in different time periods, or may also vary according to the channel condition between the main node and the next-level sub-node. Secondly, the use of additional devices for communication channel analysis and frequency band presetting does not allow effective optimization according to the change of the channel condition, and if each segment of communication between nodes is matched, the operation difficulty is increased, so that the condition becomes more complicated.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 schematically shows a flow chart of a multiband communication method according to an embodiment of the present invention. As shown in fig. 1, in an embodiment of the present invention, a multiband communication method is provided, including the following steps:
step 101, a logic topological graph corresponding to a communication network is obtained, wherein the logic topological graph comprises a plurality of nodes, and the plurality of nodes comprise a main node and at least one stage of sub-nodes.
Step 102, aiming at any one node as an initiating node in the plurality of nodes, the initiating node sends a switching frame of a preset frequency band to a passive node, and the passive node is selected from next-level sub-nodes related to the initiating node in the plurality of nodes.
And 103, the passive node switches to a preset frequency band according to the switching frame to communicate with the initiating node.
And 104, the initiating node and the passive node perform round-robin on each frequency band and acquire the communication success rate corresponding to each frequency band.
And 105, taking the frequency band with the highest communication success rate as a communication frequency band for the communication between the initiating node and the passive node.
The logical topology is used for describing how the devices communicate through the physical topology, and during communication, the connection relation between each node can be clearly represented through a corresponding logical topology graph. First, a logical topology graph corresponding to a communication network may be obtained, where the logical topology graph includes a plurality of nodes, and specifically includes a master node and at least one level of child nodes. The logical topology shown in fig. 2 includes a master node, where the master node has n primary sub-nodes, and some of the primary sub-nodes include secondary sub-nodes associated with the primary sub-nodes, and are connected layer by layer until the m-level sub-nodes of the last layer. Then each child node has its corresponding child node.
The communication network may be a high-speed carrier communication technology system based network, and is usually initiated by a master node when initiating communication, and the communication between nodes is sequentially completed according to the connection sequence of the sub-nodes in a logical topology diagram. When initiating communication, the initiating node can send a switching frame of a preset frequency band to the passive node, and the passive node can switch the frequency band to the preset frequency band according to the switching frame so as to be consistent with the frequency band of the initiating node, so that the passive node can communicate with the initiating node.
The master node may serve as a first initiating node to initiate network communication, a first-level sub-node of the master node may be called a passive node, the master node may send a switching frame of a preset frequency band to the passive node, and the passive node may switch the communication frequency band of the passive node to the preset frequency band according to the switching frame. Therefore, the frequency bands of the passive node and the initiating node for communication can be consistent, and communication can be performed. The initiating node and the passive node can also perform polling on each frequency band, that is, the initiating node and the passive node can sequentially adjust the communication frequency band to each frequency band, obtain the communication success rate of the initiating node and the passive node when performing communication through different frequency bands, and can use the frequency band with the highest communication success rate as the communication frequency band of the initiating node and the passive node, which indicates that the signals are optimal when the two nodes perform communication by using the frequency band. The communication success rate is a probability of successful communication when multiple communications are performed within a preset time, and may be a percentage of a ratio of the number of successful communications to the total number of communications. The frequency band is multiple, and each filter corresponds to a frequency band, so that the initiating node and the passive node communicate when the frequency band is switched, namely the filters are switched to communicate. Further, the SNR, i.e. the signal-to-noise ratio, i.e. the ratio of the power of the output signal of the amplifier to the power of the noise output at the same time, which is often expressed in decibels, may be recorded for each frequency band. A higher signal-to-noise ratio of a device indicates that it produces less noise. Generally, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal, the higher the quality of sound playback, and vice versa. Therefore, when two nodes communicate with each other by using the frequency band with the highest communication success rate, the communication frequency band has the maximum SNR value within the bandwidth. Therefore, when each frequency band is polled, the frequency band with the largest SNR value can be selected as the communication frequency band.
In one embodiment, as shown in fig. 3, the main node and the sub node signal receiving and transmitting channels both have 4 frequency band physical communication filters, and the different frequency band transceiver filters can be switched according to the own MCU instruction. As shown, there are 4 filters, i.e. filter 1, filter 2, filter 3 and filter 4, i.e. it means that there are 4 communication bands that can be selected by polling. The main node can initiate a communication signal to the sub-nodes, the main node and the sub-nodes can be switched into different filters at the same time to communicate through different frequency bands, and finally the filter with the highest communication success rate is selected to communicate, namely the frequency band with the highest communication success rate is selected to communicate. When the master node initiates communication, a default communication frequency band may be set to 0.7MHz to 12 MHz. The frequency band corresponding to each filter can be set by self-definition, and when the filters are switched according to the communication signals, different frequency bands are actually switched to carry out communication.
After the communication frequency band between the main node and the primary sub-node is determined, the communication frequency band between the primary byte point and the associated secondary sub-node and the communication frequency band between all subsequent nodes can be determined according to the logical topological graph, and the determination mode is consistent with that of the communication frequency band between the main node and the primary sub-node. Thus, the child nodes initiating communication may each be referred to as an initiating node, and the next level child node associated with the initiating node may be referred to as a passive node, e.g., when determining the communication band between the m-1 level child node S1 and its associated child node, i.e., the m level child node T1, then the child node S1 may be referred to as the initiating node, and the child node T1 may be referred to as the passive node. By analogy, the communication frequency bands among the nodes from the 1-level to the n-level sub-nodes in the logic topological graph can be determined, namely, the communication signal filter with the best signal matching among the nodes is determined.
In the multi-band communication method, the initiating node can send the switching frame of the preset frequency band to the passive node by acquiring the logic topological graph corresponding to the communication network, the passive node can be a next-stage sub-node associated with the initiating node from a plurality of nodes, the passive node can be switched to the preset frequency band according to the switching frame to communicate with the initiating node, the initiating node and the passive node perform round-robin on each frequency band and acquire the communication success rate corresponding to each frequency band, and the frequency band with the highest communication success rate is used as the communication frequency band for the communication between the initiating node and the passive node, the multi-band communication method can automatically analyze the communication quality between each section of nodes in real time and match the optimal communication frequency band between the nodes, and can reduce the out-of-band noise of the equipment to the minimum when a filter corresponding to the optimal communication frequency band is adopted, therefore, the communication quality of system communication can be improved, the interference of out-of-band noise on other functions of equipment is effectively avoided, and the reliability and stability of products are greatly improved.
In one embodiment, the multiband communication method further includes: after the communication frequency bands of all the initiating nodes and the passive nodes are determined, the main node sequentially communicates with the sub-nodes in the logic topological graph through the communication frequency bands according to the structure of the logic topological graph; and taking any child node as a check node, and re-determining the communication frequency band of the check node and the related upper-level father node under the condition that the communication success rate between the check node and the main node is lower than that of the communication frequency band.
Because the communication condition of the communication network may change due to the influence of environmental factors and the like, after the communication frequency bands among all the nodes are determined, that is, after the communication frequency bands of all the initiating nodes and the passive nodes are determined, the communication condition among all the nodes can be checked to determine whether the optimal communication frequency band is currently adopted or not in real time. Specifically, the master node may initiate channel detection, and sequentially communicate with child nodes in the logical topology according to the structure of the topology. That is to say, the master node may sequentially communicate with each of the child nodes in accordance with the sequence of the child nodes in the logical topology map, where the frequency band with the highest previously determined communication success rate is used, that is, the master node may communicate with each of the child nodes in the previously determined optimal communication frequency band. During the detection, any child node can be used as a detection node, and the corresponding communication success rate is recorded.
When determining whether the communication success rate of each check node in the optimal communication frequency band reaches the check standard, the communication success rate of the current check may be compared with the previously determined communication success rate of the optimal communication frequency band. If the communication success rate between the inspection node and the master node is lower than the previously determined communication success rate of the optimal communication band, the communication band of the inspection node needs to be re-determined, that is, the communication band of the inspection node and its associated upper parent node needs to be re-determined.
For example, according to the node sequence of the logical topology, the primary node a, the primary child node B1, the primary child node B2, the primary child node B3, and the secondary child node B1 have C1 and C2, respectively. First, the master node a may initiate signal checking, and take B1, B2, and B3 as checking nodes, respectively, where the master node a communicates with the first-level child nodes B1, B2, and B3, respectively, and the frequency band of communication is the frequency band with the highest communication success rate determined before, that is, the optimal communication frequency band. If the communication success rates with the main node a are not lower than those in the optimal communication frequency band when the B1 and the B2 are used as the check nodes, the B1 and the B2 are considered to pass the verification. Then, the secondary child nodes C1 and C2 may continue to be used as check nodes, and first check whether the communication success rate between B1 and C1, B1 and C2 is lower than the communication success rate in the previously confirmed optimal communication band, if so, it indicates that the communication success rate between the master node and C1 and C2 is lower than the communication success rate in the previously confirmed communication band, then C1 and C2 fail the check, and the communication bands between C1 and C2 and their associated upper level parent node B1 need to be re-confirmed.
In one embodiment, the multiband communication method further includes: acquiring the node grade number of the child node failed in verification; and according to the node sequence contained in the logical topological graph, the communication frequency band between the nodes behind the verification-failed sub-node is determined again from the node level number where the verification-failed sub-node is located.
Further, after detecting that there is a child node that fails to be verified, the node level number of the child node that fails to be verified may be obtained, and according to the structure of the logical topology map, the communication frequency bands between all child nodes after the verification node are re-determined from the node level number of the child node that fails to be verified according to the sequence of each node.
For example, the logical topology includes the master node a, the primary child nodes B1, B2, B3, the secondary child nodes C1 and C2 of the primary child node B1, and the tertiary child nodes D1 and D2 of the secondary child node C1. When both the C1 and the C2 fail to check, the node numbers of the child nodes C1 and C2 that fail to check can be obtained, and the optimal communication frequency bands between all the child nodes behind the child nodes C1 and C2 and the master node are reconfirmed. For example, if the next-level sub-node of the sub-node C1 includes D1 and D2, it is further necessary to determine whether the communication frequency band between C1 and D1, and between C1 and D2 is the optimal communication frequency band with the highest communication success rate, further acquire the next-level sub-node of D1 and D2, and re-determine the optimal communication frequency band between the next-level sub-node of D1 and D2 and the main node, and so on until all the optimal communication frequency bands between the sub-nodes and the main node are re-determined, so as to ensure that the optimal communication frequency band is used in real time for communication in the communication network.
In one embodiment, the multiband communication method further includes: after the frequency band with the highest communication success rate is used as a communication frequency band for communication between the initiating node and the passive node, acquiring a superior father node associated with the initiating node or the passive node; and respectively switching the initiating node and the passive node into the communication frequency bands of the corresponding upper-level father nodes.
After the optimal communication frequency band is matched, all the sub-nodes can be switched to the frequency band communicated with the previous sub-node or the main node by default. That is to say, after the frequency band with the highest communication success rate is used as the communication frequency band for the initiating node to communicate with the passive node, each child node acquires the corresponding previous-level node, that is, the initiating node may acquire the previous-level parent node associated therewith, and the passive node may also acquire the previous-level parent node associated therewith, and respectively switch the communication frequency band to the communication frequency band of the corresponding previous-level parent node. If the initiating node is the main node, the switching is not needed. For example, assume the node order of the logical topology diagram is the master node a, the primary child node B1, B2, B3, and the secondary child nodes of the primary child node B1 are C1 and C2. Then, after determining the optimal communication band before all the nodes, the primary child nodes B1, B2, B3 and the secondary child nodes C1, C2 all switch the communication band to the communication band of the corresponding previous parent node, that is, the primary child nodes B1, B2, B3 switch the communication band to the communication band of the corresponding parent node a, and the secondary child nodes C1, C2 switch the communication band to the communication band of the corresponding parent node B1. Therefore, when communication is initiated, the child node of the next level can quickly respond to the communication response of the parent node of the previous level, and the communication efficiency is improved.
In one embodiment, the multiband communication method further includes: under the condition that the initiating node or the passive node is determined to receive the communication signal of the corresponding superior father node, acquiring the transmission data of the superior father node; the initiating node or the passive node acquires the communication frequency band of the related next-level child node; and the initiating node or the passive node is switched to the communication frequency band of the next-level child node.
The communication is initiated by the previous node, and the next node waits for the communication initiated by the previous node and responds. Therefore, when a node receives a communication signal of a corresponding higher-level parent node, it can acquire transmission data of the higher-level parent node and prepare for communication with the next node. According to the logical topological graph, the main node belongs to the initiating node, and the nodes without the next-level child nodes belong to the passive nodes, so that the conclusion can be obtained: each child node can become an initiating node and a passive node except for the main node and the child node without the next level, so that the initiating node or the passive node can acquire the transmission data of the corresponding parent node of the previous level under the condition that the initiating node or the passive node is determined to receive the communication signal of the corresponding parent node of the previous level. If the initiating node is the master node, no parent node at the previous level exists, that is, the transmission data of the parent node at the previous level does not need to be acquired.
After the transmission data of the upper-level father node corresponding to the initiating node is acquired, the initiating node or the passive node can also acquire the communication frequency band of the lower-level child node associated with the initiating node or the passive node, and the frequency band of the initiating node or the passive node is switched to the communication frequency band of the lower-level child node, so that communication with the lower-level child node is realized. By analogy, the main node can communicate with all the sub-nodes through the predetermined optimal communication frequency band.
In one embodiment, the multiband communication method further includes: initiating communication through the main node under the condition of meeting the pre-service communication gap condition; in the communication process, each frequency band is subjected to polling among the nodes, and the frequency band with the highest communication success rate is used as the communication frequency band.
Under the condition of a service communication gap, the master node can also analyze the communication quality of the communication condition of the communication network. Firstly, whether the service communication gap is reached or not can be self-defined, and setting and adjustment can be carried out according to the actual service condition. For example, if it is known from project services that the communication service is less in a period of 3-4 am, the analysis of the communication quality of the communication network may be started in the period of time. Specifically, the quality analysis method is that a master node starts to initiate communication, two nodes are sequentially enabled to communicate according to the sequence of each node in a logical topological graph, in the communication process, polling is performed on each frequency band between the nodes, the communication success rate corresponding to each frequency band is obtained, the frequency band with the highest communication success rate is used as the communication frequency band during communication, and the optimal communication frequency band between the nodes under the current condition is determined again. This process is consistent with the method of determining the optimal communication band between nodes. That is to say, for a plurality of nodes included in the logical topology, a node that actively initiates communication may be referred to as an initiating node, a next-level sub-node associated with the initiating node may be referred to as a passive node, the initiating node and the passive node perform round-robin on each frequency band, a communication success rate corresponding to each frequency band is obtained, the frequency band with the highest communication success rate is used as a communication frequency band for communication between the initiating node and the passive node, that is, an optimal communication frequency band between the initiating node and the passive node is determined.
Meanwhile, when the optimal communication frequency band between the sub-node and the main node is re-determined, the communication frequency band of the whole communication network needs to be optimized, that is, whether the frequency bands between all the sub-nodes and the main node are the optimal communication frequency band needs to be determined. Due to the influence of the environment and the bandwidth, if the communication is still performed according to the previous communication frequency band, the communication quality is not necessarily optimal, and therefore, the communication frequency bands of all subsequent child nodes need to be optimized, so that the communication quality of the whole communication network is optimized.
In one embodiment, as shown in fig. 4, a multiband communication apparatus is provided, which includes a communication initiation module, a node communication module, and a communication band determination module, wherein:

In an embodiment, the node communication module 402 is further configured to obtain a previous parent node associated with the initiating node or the passive node after taking a frequency band with the highest communication success rate as a communication frequency band for the initiating node to communicate with the passive node; and respectively switching the initiating node and the passive node into the communication frequency bands of the corresponding upper-level father nodes.
