It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The first embodiment is as follows:
fig. 1 is a flowchart of a data hopping link management method of an internet of things system according to an embodiment of the present application, where the data hopping link management method of the internet of things system provided in this embodiment may be executed by a data hopping link management device of the internet of things system, the data hopping link management device of the internet of things system may be implemented in a software and/or hardware manner, and the data hopping link management device of the internet of things system may be formed by two or more physical entities or may be formed by one physical entity. Generally, the data hopping link management device of the internet of things system can be the internet of things system.
The following description will be given by taking an internet of things system as an example of a main body for executing a data hopping link management method of the internet of things system. Referring to fig. 1, the method for managing a data hopping transmission link of an internet of things system specifically includes:
s110, each Internet of things terminal sends a test signal to the Internet of things gateway to which the terminal belongs;
s120, the Internet of things gateway determines corresponding signal quality parameters based on the test signals, classifies each Internet of things terminal according to the signal quality parameters, determines corresponding first-level Internet of things terminal, second-level Internet of things terminal and third-level Internet of things terminal, constructs corresponding data skip transmission links based on the first-level Internet of things terminal, the second-level Internet of things terminal and the third-level Internet of things terminal, and sends the data skip transmission links to the corresponding Internet of things terminals.
The data hopping transmission link management method of the Internet of things system aims to determine the signal quality of each Internet of things terminal and each Internet of things gateway through signal testing, further classify the Internet of things terminals according to the signal quality, generate a data hopping transmission link and send the data hopping transmission link to each Internet of things terminal. Each Internet of things terminal selects superior node hop transmission service data according to the data hop transmission link, terminal identification information of the terminal is added into the service data, and after a subsequent Internet of things gateway receives the service data, whether a transmission path of the service data is legal or not is judged according to the comparison between the terminal identification information and the corresponding data hop transmission link, so that high-quality transmission and safety transmission of the service data are guaranteed, and the safe operation of system services is optimized.
Specifically, the internet of things system of the embodiment of the application comprises a plurality of internet of things terminals and internet of things gateways subordinate to the internet of things terminals, and each internet of things terminal is distributed at each position in a communication range of the internet of things gateways. When different internet of things terminals and internet of things gateways carry out service data interaction, the service data interaction is influenced by signal multipath fading, and the signal quality is different. In order to optimize the signal transmission effect and reduce the influence of signal attenuation, for part of the terminals of the internet of things with relatively poor signal communication quality with the gateway of the internet of things, other terminals of the internet of things can be selected as communication relays, and the communication relays are used for skipping service data to the gateway of the internet of things, so that better service data transmission performance is guaranteed. For this reason, referring to fig. 2, a signal test diagram of each internet of things terminal is shown. Each internet of things gateway 12 sends a test signal to the internet of things gateway 11, the test signal is sent to the internet of things gateway through each internet of things terminal for signal test, and classification of the internet of things terminals is performed based on a signal test result.
Illustratively, the internet of things gateway measures and calculates the signal quality parameter according to the relevant parameter of the test signal, and then judges the signal transmission performance between the corresponding internet of things terminal and the internet of things gateway according to the signal quality parameter. In one embodiment, the gateway of the internet of things may be provided with N diversity antennas and corresponding receivers, each antenna and corresponding receiver being configured to receive signals of a corresponding signal branch (i.e., channel). The signals are transmitted to a processor through respective receivers, and the processor is generally a baseband processor and is used for processing each diversity signal corresponding to one test signal and combining the diversity signals, so as to realize the diversity reception and the combination of the test signals of the gateway of the internet of things. It can be understood that, when a terminal of the internet of things sends a test signal to a gateway of the internet of things, multiple copies of the test signal (i.e., diversity signals) corresponding to the same signal are generated through multipath fading. And the gateway of the Internet of things independently receives each test signal copy through each diversity antenna so as to complete the diversity reception of the signal. Further, based on the test signal copies received by the diversity antennas, a combined signal is obtained through diversity combining of the test signal copies, and the combined signal is used as a test signal sent by each internet of things terminal received by the internet of things gateway. The combined test signal is received through diversity, so that the signal receiving quality can be guaranteed, the accidental signal test caused by the fact that a single channel receives data is avoided, and the signal test effect is optimized.
And further, based on the received test signals, further measuring and calculating corresponding signal quality parameters, and determining the communication quality between each Internet of things terminal and the Internet of things gateway based on the signal quality parameters. Wherein, the determination is passed. Specifically, the signal quality parameter value of the test signal is determined by the signal reception power, the signal reception strength, the channel instantaneous quality value, and/or the interference signal strength of the corresponding antenna. Wherein the channel instantaneous quality value represents the channel quality, channel matrix feedback, signal response, and/or interference information for the corresponding antenna. And measuring the various types of parameters through the corresponding test signals and the antenna parameters. Further, in order to quantize the signal quality parameter value, a calculation formula of the signal quality parameter value is provided to quantize the signal quality of the test signal, and the calculation formula of the signal quality parameter value is:
f＝ω1P+ω2d1+ω3h+ω4d2
wherein f is a signal quality parameterValue, P is signal received power, d1For signal received strength, h is the instantaneous quality value of the channel, d2For interfering signal strength, omega1，ω2，ω3And ω4The influence factors are determined according to actual tests and can be set according to the actual influence of each type of parameter on the signal quality parameter value. Based on the above signal quality parameter value calculation formula, the signal quality parameter value of each test signal can be determined. It should be noted that, in practical applications, according to different signal quality evaluation criteria, a plurality of different manners may be selected to evaluate the signal quality of each test signal, and a corresponding quantization formula is set accordingly. The above formula is only one calculation method for calculating the signal quality parameter value in the embodiment of the present application, and various different measurement and calculation formulas may be selected according to actual measurement and calculation requirements, which is not described herein again. On the other hand, if the test signal is processed in a diversity reception combining manner, the initial signal quality parameters are calculated according to the respective test signal copies of the combined signal by using the above calculation formula, and based on the determined initial signal quality parameters of the respective test signal copies, the embodiment of the present application calculates the average value by superimposing the respective initial signal quality parameters as the signal quality parameters of the combined signal. It can be understood that the higher the signal quality parameter, the better the signal transmission performance.
In addition, in one embodiment, the corresponding signal quality parameters may be determined according to a plurality of test signals by extracting the plurality of test signals corresponding to one terminal of the internet of things. The signal quality parameters are determined through a plurality of test signals, so that the condition that the test result is accidental due to a single test signal can be avoided, and the stability and effectiveness of the test result are ensured. Specifically, signal quality parameters are respectively calculated through a plurality of test signals, and a mean value is obtained according to the signal quality parameters to obtain a final signal quality parameter value, so that the signal transmission performance of the corresponding internet of things terminal and the internet of things gateway is represented.
Further, based on the signal quality parameters, the internet of things gateway grades each internet of things terminal. By setting a first signal quality threshold and a second signal quality threshold, the first signal quality threshold is greater than the second signal quality threshold. And if the signal quality parameter of the terminal of the Internet of things reaches the first signal quality parameter threshold value, the signal transmission performance of the terminal of the Internet of things and the gateway of the Internet of things is considered to be relatively excellent, and the part of terminals of the Internet of things are set as first-level terminals of the Internet of things. And if the signal quality parameter of the terminal of the Internet of things is between the first signal quality parameter threshold and the second signal quality threshold, considering that the signal transmission performance of the terminal of the Internet of things and the gateway of the Internet of things is relatively normal, and setting the part of terminals of the Internet of things as secondary terminals of the Internet of things. And if the signal quality parameter of the terminal of the internet of things is lower than the second signal quality parameter threshold value, the signal transmission performance of the terminal of the internet of things and the gateway of the internet of things is considered to be relatively poor, and the part of terminals of the internet of things are set as three-level terminals of the internet of things. Therefore, the classification of each internet of things terminal of the gateway can be realized, and the corresponding first-level internet of things terminal, second-level internet of things terminal and third-level internet of things terminal are determined. In an embodiment, a set number of internet of things terminals with the best signal quality parameters can be selected as first-level internet of things terminals according to the signal quality parameters corresponding to the internet of things terminals, and a set number of internet of things terminals with larger signal quality parameters are selected as second-level internet of things terminals from the rest of internet of things terminals, so that the rest of internet of things terminals are finally third-level internet of things terminals. And determining the grade of each Internet of things terminal, and determining a corresponding first-level Internet of things terminal, a second-level Internet of things terminal and a third-level Internet of things terminal.
After the grading of each internet of things terminal is determined, the internet of things terminal constructs each corresponding data jump transmission link based on a first-level internet of things terminal, a second-level internet of things terminal and a third-level internet of things terminal in the communication range of the internet of things terminal. The method comprises the steps that a second-level Internet of things terminal is selected as a superior node within a communication range of a third-level Internet of things terminal, a first-level Internet of things terminal is selected as a superior node within the communication range of the second-level Internet of things terminal, the Internet of things gateway serves as the superior node of the first-level Internet of things terminal, and corresponding data skip transmission links are constructed on the basis of the first-level Internet of things terminal, the second-level Internet of things terminal and the superior node of the third-level Internet of things terminal. The internet of things gateway determines the distribution position of each internet of things terminal in the communication range of the internet of things gateway in advance, and then the superior node closest to each internet of things terminal can be determined. When the service data are transmitted from the third-level internet of things terminal, the data hopping transmission link comprises a third-level internet of things terminal, a second-level internet of things terminal, a first-level internet of things terminal and a gateway, for the service data of the second-level internet of things terminal, the data hopping transmission link comprises a second-level internet of things terminal, a first-level internet of things terminal and a gateway, and the like, and the hopping transmission path of the service data of each internet of things terminal can be determined according to the upper-level node of each internet of things terminal, namely the data hopping transmission link. It can be understood that the data hopping transmission link identifies a superior node of each internet of things terminal, and when service data is transmitted, each internet of things terminal transmits the service data by using the superior node as a receiving end of the service data. Therefore, the service data can be subjected to skip transmission step by step among the terminals of the Internet of things, and finally the service data is uploaded to the gateway of the Internet of things through the terminals of the first-stage Internet of things.
Further, after the internet of things gateway completes the construction of the data hopping link, referring to fig. 3, the internet of things gateway 11 distributes the corresponding data hopping link to each internet of things terminal 12, so that each internet of things terminal 12 defines its own classification, and performs service data transmission according to its own data hopping link.
S130, when the service data is uploaded, each Internet of things terminal transmits the service data based on the corresponding data hopping transmission link, and adds own terminal identification information when transmitting the service data.
S140, the gateway of the Internet of things receives the service data, inquires the corresponding data hopping transmission link based on a plurality of pieces of terminal identification information contained in the service data, and verifies whether the service data is legal or not.
Further, referring to fig. 4, when each internet of things terminal 12 performs service data hopping according to the data hopping transmission link, according to the higher node identified in the data hopping transmission link, the service data of the terminal or the service data of the summarized lower node is transmitted to the corresponding higher node, and finally the service data is transmitted to the internet of things gateway 11. And no matter the service data of the user or the service data summarized by the lower node is uploaded, the terminal identification information is added to the service data when the service data is transmitted. For example, when the service data from the third-level internet of things terminal is jumped to the internet of things gateway, the service data needs to be jumped through the second-level internet of things terminal and the first-level internet of things terminal, and when the service data is transmitted to the internet of things gateway, the service data needs to include the corresponding terminal identification information of the third-level internet of things terminal, the second-level internet of things terminal and the first-level internet of things terminal. Correspondingly, after the internet of things gateway receives the service data, a data hopping transmission link corresponding to the internet of things terminal is extracted according to the internet of things terminal to which the service data belongs, the data hopping transmission link is compared with terminal identification information contained in the service data, if the data hopping transmission link is consistent with the terminal identification information contained in the service data, the transmission path of the service data is legal, otherwise, the service data is illegally transmitted, and at the moment, the service data is discarded without corresponding processing. Therefore, the safety of service data transmission is guaranteed, and the influence on the service processing of the system due to data counterfeiting is avoided. Taking the service data uploaded by a certain three-level internet of things terminal as an example, after the internet of things gateway receives the service data, according to the three-level internet of things terminal to which the service data belongs, a data jump transmission link of the service data corresponding to the internet of things terminal can be inquired. Then, the data hopping transmission link is extracted and compared with each terminal identification information (namely, the terminal identification information of the third-level internet of things terminal, the second-level internet of things terminal and the first-level internet of things terminal) contained in the service data, so as to judge whether the data hopping transmission link is legal or not.
In one embodiment, the internet of things gateway further configures a corresponding session key for each data hopping transmission link, and sends the data hopping transmission link and the corresponding session key to each corresponding internet of things terminal; correspondingly, when each internet of things terminal uploads service data, the service data is transmitted based on the corresponding data jump transmission link, and the method further comprises the following steps: and performing service data transmission based on the corresponding data hopping transmission link and the session key. Specifically, based on the data hopping transmission link, the embodiment of the application configures a corresponding session key for each data hopping transmission link, so that encrypted transmission of service data is performed according to the session key, and the security of service data transmission is guaranteed. Different session keys are correspondingly configured according to different data hopping links, the data hopping links and the corresponding session keys are sent to all the Internet of things terminals, a binding relationship between the data hopping links and the corresponding session keys is established and stored, and the binding relationship is used for inquiring the session keys according to the data hopping links corresponding to the service data to decrypt the service data. By configuring different session keys, the independence of service data transmission can be guaranteed, the service data transmission is not influenced mutually, and the safety of the service data transmission can be improved. It should be noted that, when the data hopping transmission link and the corresponding session key are sent down, all the internet of things terminals appearing in the data hopping transmission link will receive the data hopping transmission link and the corresponding session key information. When the gateway of the internet of things issues the data hopping transmission link and the corresponding session key, the gateway of the internet of things receives one data hopping transmission link and the corresponding session key for the three-level internet of things terminal. For the secondary internet of things terminal, according to the number of the lower nodes of the secondary internet of things terminal, a plurality of data hopping transmission links (data hopping transmission links containing self service data) can be received, and the secondary internet of things terminal plays the role of the upper nodes or the lowest level nodes in the data hopping transmission links. Similarly, for the first-level internet of things terminal, a plurality of data hopping transmission links can be received, and the first-level internet of things terminal plays the role of a superior node or a lowest-level node in the data hopping transmission links. And corresponding to the three-level Internet of things terminal, because the Internet of things gateway only issues one data jump transmission link and a session key, when data jump transmission occurs, service data is encrypted and uploaded according to the session key. For the second-level internet of things terminal and the first-level internet of things terminal, when receiving the service data sent by the lower-level node for decryption, the corresponding data hopping transmission link needs to be determined according to the internet of things terminal through which the service data passes, and then the corresponding session key is selected for decryption of the service data. And when the service data is further uploaded, encrypting and uploading the service data by using the session key corresponding to the data hopping transmission link which is the lowest level node per se, so as to encrypt and transmit the service data. It can be understood that, corresponding to the three-level internet of things terminal, since it is only used for uploading own service data, it only receives the data hopping transmission link related to the own service data. For the second-level internet of things terminal and the first-level internet of things terminal, since the second-level internet of things terminal and the first-level internet of things terminal need to forward the service data summarized by the lower-level node, the second-level internet of things terminal and the first-level internet of things terminal need to receive a data hopping transmission link and a related session key of the service data of the related lower-level node in addition to a data hopping transmission link of the service data of the second-level internet of things terminal and the first-level internet of.
Illustratively, when each terminal of the internet of things uploads the service data, the corresponding session key is used to encrypt the service data, and the service data is skipped to a corresponding upper node based on the corresponding data hopping link, and when the upper node receives the service data, the session key used by the current service data is determined based on the corresponding data hopping link, and the corresponding session key is extracted to decrypt the service data. And determining the corresponding data jump transmission link according to the grade of each Internet of things terminal. And when the service data is subjected to the skip transmission, the service data is subjected to the skip transmission according to the corresponding transmission path. And the service data uploaded by the second-level internet of things terminal and the first-level internet of things terminal serving as the upper-level nodes comprises the summary of the lower-level nodes and the service data of the lower-level nodes. When the service data is encrypted and transmitted, the three-level internet of things terminal only has one data hopping transmission link (namely 3-2-1), and the three-level internet of things terminal uses the session key corresponding to the data hopping transmission link to upload the service data. And when the second-level Internet of things terminal receives the service data sent by the third-level Internet of things terminal, the session key corresponding to the data hopping transmission link (3-2-1) is used for decrypting the service data. Further, when the second-level internet of things terminal uploads the service data to the first-level internet of things terminal, the service data is encrypted and uploaded by determining the session key corresponding to the data skip transmission link (2-1). And by analogy, the service data is finally transmitted to the gateway of the Internet of things, and the encryption transmission of the data is completed.
Further, in an embodiment, after configuring a session key for each data hopping transmission link, the internet of things gateway updates each session key every other set session security management period, and issues the updated session key to each internet of things terminal according to the data hopping transmission link in the binding relationship to update the session key. The session key is periodically updated, so that the security of the session key can be guaranteed, the difficulty of service data decryption is increased, and the security of service data transmission is further improved.
In one embodiment, the internet of things gateway modifies the corresponding data hopping transmission link based on the error rate detection result by obtaining the error rate detection result of the service data received by the second-level internet of things terminal, the third-level internet of things terminal or the internet of things gateway. It can be understood that when the second-level internet of things terminal, the third-level internet of things terminal or the internet of things gateway receives the service data uploaded by the lower-level node, if the error rate of the service data is detected to be relatively high for a continuously set number of times, the data skip transmission link of the current service data needs to be further replaced to ensure the signal stability of service data transmission. According to the error rate detection result of the second-level internet of things terminal, the third-level internet of things terminal or the internet of things gateway for receiving the service data, if the error rate information of the continuous set times reaches the set error rate threshold value, the signal transmission performance of the corresponding service data is relatively poor, in order to guarantee the transmission stability of the corresponding service data and improve the signal quality of the service data, the data jump transmission link is correspondingly modified, and the modified data jump transmission link is used for transmitting the corresponding service data.
In one embodiment, each internet of things terminal sends the test signal to the internet of things gateway every other set period, and the internet of things gateway judges whether to modify the classification of each internet of things terminal based on a signal test result of the test signal and correspondingly modifies the data hopping transmission link.

It can be understood that if the signal quality parameter of the test signal between a certain internet of things terminal and the internet of things gateway changes significantly and reaches the classification standard of another level, the internet of things terminal is reclassified according to the signal test result, and the corresponding data hopping transmission link is reconstructed according to the reclassification result. For example, if the signal quality parameter of the second-level internet-of-things terminal reaches the corresponding signal quality parameter threshold value, which indicates that the signal transmission performance of the second-level internet-of-things terminal and the internet-of-things gateway is relatively good, the second-level internet-of-things terminal is upgraded to be the first-level internet-of-things terminal, so that the second-level internet-of-things terminal directly performs service data interaction with the internet-of-things gateway, data jumping is avoided, a data processing flow is increased, and the service data transmission.
