Embodiments of the invention

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive work are all within the scope of the present invention.

[0031] Embodiment 1 Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method for addressing information of an Internet of Things terminal according to Embodiment 1 of the present invention. The method may include the following steps: [0032] First, the Internet of Things architecture applied in the embodiment of the present invention is illustrated by using FIG. 2, and the Internet of Things architecture is divided into three layers, and the bottom-up is: the sensing layer, the network layer, and the application layer. The sensing layer is the core of the Internet of Things and is a key part of information collection. The sensing layer includes a large number of terminal devices, such as QR code tags and readers, RFID tags and readers, cameras, GPS, sensors, etc. The main function is to identify objects and collect information. The network layer transmits the collected information accurately and accurately through the integration of various mobile communication networks and the Internet. The network layer can be regarded as composed of a plurality of network nodes, and the information collected by the terminal device is forwarded and transmitted to the application layer through the network node at the network layer. The application layer provides data analysis, control, and the Internet of Things human-machine interface.

[0033] Taking one of the network nodes of the network layer as an example, an addressing method of terminal information in the Internet of Things architecture is illustrated.

[0034] Step S101: Receive terminal information, including a public label, sent by the sensing layer, where the public label includes a data type and a transmission direction.

[0035] In the embodiment of the present invention, the data collected by the terminal device of the sensing layer is sent to the network node of the network layer in the form of terminal information, and the terminal information includes at least a public label. The public tag includes at least the data type and the transfer direction. 3 is a packet format of terminal information. Taking FIG. 3 as an example, the public tag includes the data type and transmission direction collected by the terminal device, and may also include the terminal ID and signal frequency of the collected data, but the terminal ID and the signal frequency may be Set to empty, you can also reserve to store other fields. The private label includes the specific data and frame check collected by the terminal device. Bytes are also reserved for future expansion. It should be noted that FIG. 3 is only used as an example, and is not intended to limit the present invention, as long as the public tag is included, and the common tag includes both the data type and the transmission direction within the protection scope of the present invention. In practical applications, different packet formats can be evolved based on data types and transport pointers in combination with other fields. It should be noted that the transmission pointer may also be set to be empty.

[0036] The data type refers to which type of data the data collected by the terminal device is. For example, humidity and temperature are different data types, and different character representations can be set for humidity and temperature, respectively. The transmission direction refers to a direction of transmission, which may indicate a direction to a final application layer address, and may also indicate a direction in which data is transmitted in a network node of the network layer. For example, different characters respectively indicate that the network node transmission is searched for, Find the network node transmission with the best network performance, etc., which can be set according to the actual situation. In practical applications, because it is a transmission mechanism for the receiver, the transmission pointer can also be set to null, and the network node transmits the terminal information to the application layer, and the application layer determines whether to receive the terminal information. [0037] It should be noted that the terminal information including the public label sent by the receiving sensing layer indicates that the received terminal information is originally sent by the sensing layer, and may pass through other network nodes, or may be directly received sensing layer terminals. Terminal information sent by the device.

[0038] Step S102: Receive data request information sent by an application layer, where the data request information includes an application layer address and a requested data type.

[0039] In the embodiment of the present invention, when the application layer needs some data, it can not only passively receive the terminal information, but also analyze whether the received terminal information is required by itself, and if necessary, extract the data therein. , discard if not needed. The application layer may also send data request information according to its own needs, the data request information includes an application layer address and a requested data type, and the data packet format of the data request information is simpler than the data packet format of the terminal information. It only includes the data type and its own address. It should be noted that the data request information exemplified in the embodiment of the present invention is a data packet format that only needs to include a data type and an address of its own in order to simplify the data packet format and save network traffic. It is also possible to evolve on this basis, for example, data request information including a data type and its own address is within the scope of the present invention. The data type corresponds to the terminal information, and may be temperature, humidity, or the like. The temperature corresponding to the terminal information uses the same character, and the humidity uses the same character. Relative to the terminal information sent by a large number of terminal devices, and the terminal information may be sent at a higher frequency, when a large amount of terminal information generated by a large number of terminal devices or a large amount of terminal information generated at a high frequency has no direction in all directions. The spread of the network may cause network congestion. However, since the application layer is very small in terms of a large number of terminal devices, when the application layer needs some kind of data, it can issue a data request message. As a network node of the network layer, it is possible to receive the terminal information including the public label sent by the sensing layer, and it is also possible to receive the data request information sent by the application layer.

[0040] It should be noted that the data request information sent by the receiving application layer indicates that the received data request information is originally sent by the application layer, may pass through other network nodes, or may be directly sent by the application layer. Request information.

[0041] Step S103: Perform pairing according to the received terminal information and the data request information.

[0042] In the embodiment of the present invention, pairing according to the received terminal information and the data request information refers to pairing according to the received terminal information and the data type in the data request information. There are many network nodes distributed in the network layer. The network nodes are used to forward and transmit terminal information. Each terminal information is sent from the end of the sensing layer. The end device to the application layer may pass through only one network node or may pass through many network nodes. The network node has the functions of receiving and sending information. However, some terminal devices of the sensing layer have the function of receiving information, and some have no function of receiving information. Therefore, the data request information sent by the application layer is transmitted at the network layer, and is not necessarily transmitted. The terminal device to the sensing layer. Each network node in the peer network layer may receive multiple terminal information and may receive multiple data request information. Therefore, the work of pairing according to the received terminal information and data request information is completed at the network node of the network layer.

[0043] Specifically, the network node received by the network layer has two terminal information, and the data types are: temperature, humidity, and received data request information. The requested data types are: pressure, temperature, and water level. . The network node only needs to analyze the data type in the public tag of the terminal information and the data type in the analysis data request information. It is found that the terminal information of the received terminal information in which the data type is temperature and the data request information whose data type is temperature in the received data request information can be paired successfully, indicating that they have the same data type. If the data type in the public label of the terminal information is consistent with the data type in the data request information, it indicates that the received terminal information is data requested in the data request information sent by the application layer, and does not need to analyze the private label in the terminal information. Specific data content.

[0044] Step S104: If the terminal information is successfully paired with the data request information, calculate a transmission path according to the network node address where the terminal information is currently located and the application layer address in the data request information.

[0045] In the embodiment of the present invention, if the terminal information is successfully paired with the data request information, it indicates that the data requested by the data request information received by the network node is successfully paired terminal information. Then you need to analyze the address of the application layer in the data request information. The transmission path may be calculated according to the network node address where the terminal information is currently located and the application layer address in the data request information. Actually, a large number of network nodes are distributed in the network layer. There may be a plurality of transmission paths between the network node address where the terminal information is currently located and the application layer address in the data request information. Actually, the transmission path is not unique. The network node will exchange information with other connected network nodes. Each forwarding node will establish its own neighborhood table to form a logical network tree. These information are shared with each other, thus allowing the network node to make independent decisions and reasonably selecting the effective address to reach the application layer. path.

[0046] As a preferred embodiment, calculating the transmission path according to the network node address where the terminal information is currently located and the application layer address in the data request information, including: according to the network node address where the terminal information is currently located, The application layer address in the data request information calculates the shortest transmission path. [0047] In the embodiment of the present invention, the shortest transmission path refers to finding a path with the smallest right between two nodes of an weight map, that is, starting from the network node address where the terminal information is currently located. Along the path through which the network node of the network layer reaches the application layer address, each time a network node calculates a weight, until the path to which the sum of the application layer address ownership values is the smallest is the shortest transmission path. The weight is related to a load, an available bandwidth, and the like of a network node that receives the terminal information. Specifically, it is more reliable to choose a path that is more reliable than a network node or a more direct but load-bearing transmission path that needs to be balanced by weights. In other words, for example, whether the traffic conditions in the peak section are selected to be crowded highways or whether the city street bypass is more effective can be selected by setting weights.

[0048] In the process of calculating the transmission path, it is also necessary to consider whether the forwarding node can directly connect directly with the Internet, so that an IP path can be used to provide an optimal path to the address of the application layer, but in practice, many network nodes cannot be found. The direct connection path with the Internet can only be forwarded through other network nodes, so the weight is also related to whether the network node receiving the terminal information can directly connect to the Internet.

[0049] In summary, the shortest transmission path is related to the number of network nodes passing, the load of each network node receiving the terminal information, the available bandwidth, whether it can be directly connected to the Internet, and reliability. Specifically, the shortest transmission path can be calculated. Different weight values can be set according to actual conditions. However, it should be noted that the number of network nodes that have passed above, the load of each network node that receives terminal information, the available bandwidth, whether it can be directly connected to the Internet, These factors are not used to limit the present invention. Other factors that need to be considered may be added according to actual conditions, and one or more factors may not be considered according to actual conditions.

[0050] The decision of the transmission path also needs to be periodically adjusted to cope with network disturbances or failures, including new network elements and link quality information updates. Once new network nodes or transmission paths are added to the network layer, neighboring network nodes will immediately reevaluate their path decisions to ensure a valid path to the application layer. The network node also performs a neighbor node update search every other time to find potential new paths and new neighboring network nodes.

[0051] In the embodiment of the present invention, the shortest transmission path does not refer to the shortest distance, but is based on the number of network nodes that pass, the load of each network node that receives terminal information, the available bandwidth, and whether it can be directly connected to the Internet. , the reliability and other factors determine the optimal transmission path. By considering the network section that passes through The shortest transmission path calculated by the number of points, the load of each network node receiving the terminal information, the available bandwidth, whether it can be directly connected to the Internet, reliability, etc., and the weight value calculation for these factors can quickly and effectively transmit the terminal information. An application layer address corresponding to the data request information successfully paired with the terminal information.

[0052] Step S105: Send the terminal information according to the transmission path to an application layer address pointed to by the data request information that is successfully paired with the terminal information.

In the embodiment of the present invention, after the transmission path is calculated, the terminal information may be sent to an application layer address pointed to by the data request information that the terminal information is successfully paired. However, in the actual transmission process, there may be a failure of a forwarding node on the transmission path or a significant change in the transmission rate. Therefore, it is necessary to consider the alternative path or the network according to the terminal information. The node recalculates the transmission path, and the calculation process is the same as in step S104.

[0054] Optionally, if the terminal information of the same data type is received again, according to the correspondence between the successfully paired terminal information and the data request information, the terminal information with the same data type is sent to the corresponding relationship according to the corresponding relationship. The application layer address in the data request information.

[0055] In the embodiment of the present invention, the network node may associate the successfully paired terminal information with the data request information, and the actually established correspondence relationship is only the correspondence between the data type and the application layer address, and if the terminal is received again. The data type of the information is the same as the data type in the correspondence between the pre-established data type and the application layer address, and the terminal information may be sent to the application layer address in the data request information according to the correspondence relationship according to the correspondence.

[0056] By pairing the successfully matched terminal information with the data request information, the re-received terminal information can be paired with the data request information in the established correspondence, even if the current network node does not receive the data request information. The terminal information may be sent to the application layer address of the data request information having the same data type according to the correspondence, thereby improving the efficiency of terminal information transmission.

[0057] As a preferred embodiment, in the three-layer architecture of the Internet of Things, a layer may be further established between the application layer and the network layer, which may be called a data request layer, and the data request layer is used to receive the application layer. Data request information, and packet request information having the same data type in the received data request information is packaged and sent back to each network node of the network layer, so that the data request information sent by multiple addresses of the application layer can be packaged into one data request. Information is transmitted to save network traffic. [0058] The present invention performs pairing according to the received terminal information and the data request information by receiving the terminal information including the public label and the data request information sent by the application layer, if the terminal information and the data request information If the pairing is successful, the transmission path is calculated according to the network node address where the terminal information is currently located and the application layer address in the data request information; and the data request information is successfully sent according to the transmission path to the terminal information. Application layer address. Since the data request information sent by the application layer can be received in reverse, the data type of the terminal information and the data type of the data request information can be paired, so that the terminal information of the sensing layer can be transmitted according to the calculated transmission path, thereby avoiding the terminal. The problem of network congestion, data loss, and transmission delay caused by the spread of information in all directions can provide a safe and reliable method of terminal data transmission.

[0059] Embodiment 2: Referring to FIG. 4, FIG. 4 is a schematic flowchart of the method for addressing information of the Internet of Things terminal according to Embodiment 2 of the present invention. On the basis of Embodiment 1, the following steps are added.

[0060] Step S401: Perform pairing according to the received terminal information and the data request information.

[0061] Step S402: If the terminal information and the data request information are not successfully paired, the data request information having the same data type is packaged and sent to other network nodes.

In the embodiment of the present invention, since there are many network nodes in the network layer, although the terminal information is transmitted in the direction of the application layer, the data request information is propagated from the application layer to the network node of the network layer. However, since the terminal information and the data request information select a preferred network node according to other network nodes connected to the current network node, the terminal information and the data request information are transmitted, so in some network nodes. It is possible that only the terminal information may be received, and the data request information may only be received. Even if the received terminal information and the data request information are received, the terminal information and the data request information having the same data type may not be the same. . In this case, the terminal information and the data request information cannot be successfully paired, that is, the data type requested by the data request information sent by the application layer is not the data type carried by the terminal information received by the current network node. In this case, the terminal information and the data request information need to be sent to other network nodes.

[0063] As a preferred embodiment, if the terminal information and the data request information are not successfully paired, the data request information is stored in a current network node, so as to receive the same as the data request information. After the terminal information of the data type, the transmission path is calculated according to the network node address where the terminal information is currently located and the application layer address in the data request information; The terminal information is addressed to an application layer address pointed to by the data request information that is successfully paired with the terminal information.

[0064] In the embodiment of the present invention, if the terminal information and the data request information are not successfully paired, if the data request information is retained at the current network node, the other network nodes receive the The data request information has terminal information of the same data type, and the received terminal information cannot be paired, so the data request information must be sent to other network nodes, but the current network node may also receive and The data request information has terminal information of the same data type, so it is necessary to consider storing the data request information locally in the current network node before sending the data request information to other network nodes, so as to receive and After the data request information has the terminal information of the same data type, the terminal information having the same data type as the data request information is sent to the application layer address pointed by the data request information, thereby improving the efficiency of addressing the terminal information. . If the storage space of the network node is saved, the data request information in the storage space of the network node may be backed up and deleted periodically. For example, you can set the data request information in the storage space to be deleted and deleted at regular intervals, or you can set the data request information in the storage space 7 days ago to be deleted. Specifically, it can be set according to the actual situation.

[0065] As a preferred embodiment, if the terminal information and the data request information are not successfully paired, the terminal information is stored in a current network node, so as to receive the same data type as the terminal information. After the data request information, the transmission path is calculated according to the current network node address and the application layer address in the data request information; and the terminal information is sent according to the transmission path to the data request information that is successfully paired with the terminal information. Application layer address.

[0066] In the embodiment of the present invention, if the terminal information and the data request information are not successfully paired, if the terminal information is retained at the current network node, the other network nodes receive the terminal even if The information has the same data type data request information, and the received data request information cannot be paired, so the terminal information must be sent to other network nodes, but the current network node may also receive the terminal later. The information has data request information of the same data type, so it is necessary to consider storing the terminal information locally in the current network node before sending the terminal information to other network nodes, so as to receive the terminal and the terminal. After the information has the data request information of the same data type, the terminal information having the same data type as the data request information is sent to the application layer address pointed by the data request information, thereby improving the addressing effect of the terminal information. Rate. If the storage space of the network node is saved, the terminal information in the storage space of the network node may be backed up periodically. For example, it is possible to set the terminal information in the storage space to be deleted and deleted at regular intervals, or to delete the terminal information in the storage space 7 days ago. Specifically, it can be set according to the actual situation.

[0067] As a preferred embodiment, data request information having the same data type may be packaged and transmitted to other network nodes. The data request information having the same data type includes not only the received data request information but also the data request information stored in the local backup, which can save network traffic.

[0068] Step S403: If the terminal information and the data request information are not successfully paired, send the terminal information to another network node.

[0069] Step S4031: If the public tag indicates the data type and the transmission direction of the terminal information, the terminal information is transmitted according to the data type and the transmission direction.

[0070] In the embodiment of the present invention, the terminal information includes a public label, where the public label includes at least a data type and a transmission direction, and if the transmission direction of the terminal information indicates a transmission direction, The data type and transmission are directed to the transmission of the terminal information.

[0071] Specifically, if the transmission indication indicates that the transmission is to the nearest neighboring network node of the current network node, the terminal information is transmitted to the nearest neighboring network node of the current network node, if the transmission The point indicates that the network node transmission with the best network performance is found, and then the network node with the best network performance among the other network nodes that the current network node can connect to is transmitted. Different transfer pointers can be represented by different characters.

[0072] Step S4032: If the public tag does not indicate the data type and the transmission direction of the terminal information, the terminal information is transmitted to other network nodes.

[0073] In the embodiment of the present invention, when the transmission pointing field is empty, or the meaning of the character stored in the transmission pointing field is empty, the terminal information is transmitted to another adjacent network node. Just fine.

[0074] As a preferred embodiment, after the terminal information is sent from the current network node, the sent information is sent to the previous network node of the current network node, so that the previous network node will send The terminal information is deleted;

[0075] if the network node where the terminal information is located does not send the terminal information in the first predetermined time interval Sending unsent information to the previous network node that sends the terminal information to the current network node, so that the previous network node sends the terminal information to other network nodes, so that other network nodes send the terminal information to the application layer. ;

[0076] if the current network node receives the unsent information of the next network node to which the terminal information is sent or does not receive the transmitted information or the unsent information sent by the next network node in the second predetermined time interval, The terminal information is transmitted to other network nodes so that other network nodes send the terminal information to the application layer.

[0077] In the embodiment of the present invention, the following four situations are included:

[0078] after the network node sends the terminal information, the transmitted information is sent to the previous network node; [0079] the terminal information is not sent out in the first predetermined time of the network node, and the network node is forwarded. Send unsent information;

[0080] after receiving the unsent information sent by the next network node, the network node sends the terminal information to other network nodes;

[0081] The network node does not receive the sent or sent information sent by the next network node in the second predetermined time, and sends the terminal information to other network nodes.

Specifically, we assume that a piece of terminal information is transmitted from the network node 1 to the current network node 2, the current network node 2 is ready to transmit the terminal information to the network node 3, and the terminal is present at the current network node 2. After the information is transmitted to the network node 3, the current network node 2 needs to send a message to the network node 1 that the terminal information has been sent out, and the network node 1 has received the terminal information by transmitting the terminal information. The information is deleted after the information is deleted. If the network node 2 does not transmit the terminal information to other network nodes within the first predetermined time interval, the unsent information is transmitted to the network node 1. If the network node 3 does not send the terminal information to the network node 4 after receiving the terminal information, it needs to send an unsent information to the network node 2, and the network node 2 receives the After the information is not sent, the terminal information is sent to other network nodes. If the network node 2 does not receive the information transmitted by the network node 3 that the terminal information has been transmitted or not transmitted within the second predetermined time, the terminal information is transmitted to other network nodes.

In the embodiment of the present invention, the process of data transmission is introduced by using FIG. 5 as an example, where 51 represents an application layer address that the application layer sends data request information, and may be represented by a convergence unit, where 52 represents a network node in the network layer. 53 denotes a terminal device of the sensing layer, and a broken line denotes a transmission process of possible data. A solid line is taken as an example to illustrate a transmission process of a terminal information and a piece of data request information. 521, 523 respectively represent one network node in the network layer, 522 represents a network node for pairing terminal information and data request information, and 531 represents one of the terminal devices of the sensing layer. It should be noted that FIG. 3 is only used as an example, and is not used to limit the present invention. It may be applied to different scenarios, and may also increase or decrease the number of devices in the application layer, the sensing layer network node, and the sensing layer terminal device.

[0087] Specifically, the terminal device 531 determines the collected data information to be in the form of a data packet by the data generator, where the data packet includes a public label and a private label, wherein the public label includes the data type. The terminal device sends the generated terminal information including the public label to the network node 523 of the network layer, and only shows the sending to the network node 523. In an actual application, the network node may be configured to receive the specified multiple terminal devices. The terminal information, that is, each terminal device can only be sent to a specific network node, or each terminal device can be sent to at least one network node, and the specific device can be set according to actual conditions. [0088] After receiving the terminal information received by the terminal device 531, the network node 523 first parses the public label, and does not need to parse the private label. Generally, the data information collected by the terminal device is stored in the private label, and the data type and the transmission point are stored in the public label. in. The network node 523 can compare the data type of the received data request information by parsing the received public information of the terminal information, and if there is no matching data request information, the terminal information is directed according to the transmission in the public label. The terminal information is transmitted to other network nodes, and the terminal information is transmitted to the network node 522 as shown. It should be noted that, if the received terminal information is not successfully paired at the network node 523, the network node 523 stores the terminal information in the current network node and sends it again, so as to receive the information after the sending. After having the data request information of the same data type, the terminal information stored in the network node 523 is transmitted to the aggregation unit address of the data request information having the same data type as the terminal information.

The data type is used for pairing by the network node, and the address of the aggregation unit is used by the network node to send the successfully paired terminal information to the address of the convergence unit. As shown, the aggregation unit 51 transmits the data request information to the network node 521.

[0090] The network node 521 pairs the received data request information with the received terminal information, and if there is no successfully paired terminal information, sends the data request information to other network nodes. The data request information is sent to the network node 522 as shown in the figure. It should be noted that, if the received data request information is not successfully paired at the network node 521, the network node 521 stores the data request information in the current network node and sends it again, so as to be received and sent after being sent out. The data request information has terminal information of the same data type.

[0091] The network node 522 successfully pairs the received terminal information with the received data request information, calculates a transmission path according to the current address and the address of the convergence unit in the data request information, and uses the terminal according to the transmission path. The information is sent to an application layer address in the data request information having the same data type as the terminal information. The transmission path is not limited to the reverse path of the path in which the data request information is transmitted, for example: 522-521-51; it may also be all transmission paths from 522 to 51, and specifically according to the set transmission path policy Make a choice.
