In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. 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 transmission link management method based on signal testing according to an embodiment of the present application, where the data-hopping transmission link management method based on signal testing provided in this embodiment may be executed by a data-hopping transmission link management device based on signal testing, the data-hopping transmission link management device based on signal testing may be implemented in a software and/or hardware manner, and the data-hopping transmission link management device based on signal testing may be formed by two or more physical entities or may be formed by one physical entity. Generally, the data hopping link management device based on signal testing can be an internet of things system.
The following description will be given taking an internet of things system as an example of a main body of a data hopping link management method for performing signal test. Referring to fig. 1, the data hopping transmission link management method based on signal testing 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 based on the signal test aims at determining the signal quality of each Internet of things terminal and each Internet of things gateway through the signal test, further grading the Internet of things terminals according to the signal quality, generating the data hopping transmission link and issuing the data hopping transmission link to each Internet of things terminal. Each Internet of things terminal selects superior node hopping transmission service data according to the data hopping transmission link, performs signal test when the service data hopping transmission is performed, detects signal quality parameters or bit error rates of the service data, judges whether the corresponding data hopping transmission link is modified or not according to the signal quality parameters or the bit error rates, further guarantees high-quality transmission and transmission of the service data, and optimizes system service operation.
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
where f is the signal quality parameter value, P is the signal received power, d1For signal received strength, h is the channelInstantaneous quality value, 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 each Internet of things terminal uploads service data, service data are transmitted based on the corresponding data hopping transmission link;
s140, summarizing signal quality parameter detection results or error rate detection results when the second-level Internet of things terminal, the first-level Internet of things terminal and the Internet of things gateway receive corresponding service data, and modifying the corresponding data hopping transmission link based on the corresponding signal quality parameter detection results or error rate detection results.
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.
Specifically, when the second-level internet of things terminal, the first-level internet of things terminal and the internet of things gateway receive the service data uploaded by the lower-level node, signal quality parameter detection or error rate detection of the service data is also performed corresponding to the received service data, so that a corresponding signal quality parameter detection result or error rate detection result is obtained. The signal quality parameter detection result or the error rate detection result represents the signal transmission performance between the current corresponding lower node and the upper node. If the signal quality parameter detection result is lower than the set threshold or the error rate detection result reaches the set threshold, it indicates that the signal transmission performance between the current corresponding lower node and the upper node is relatively poor, and at this time, the upper node of the corresponding lower node in the data hopping transmission link needs to be changed in order to avoid influencing the transmission of the service data. Taking the third-level internet of things terminal as an example to determine the superior node again, referring to the manner of determining the superior node in step S120, the second-level internet of things terminal (except the original superior node) closest to the third-level internet of things terminal is selected in the communication range of the corresponding third-level internet of things terminal, and the second-level internet of things terminal is determined as the superior node again. And modifying the corresponding data jump transmission link according to the upper node redetermined by the three-level Internet of things terminal. And when the third-level Internet of things terminal uploads the service data, the modified data hop transmission link is used for transmitting the service data. 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 it is detected that the error rate of the service data is relatively high or the signal quality parameter is relatively low, the data hopping transmission link of the current service data needs to be further replaced to ensure the signal stability of service data transmission. In an embodiment, the method may further include receiving a bit error rate detection result or a signal quality parameter detection result of the service data according to the second-level internet-of-things terminal, the third-level internet-of-things terminal or the internet-of-things gateway, if it is detected that the bit error rate of the service data reaches a set bit error rate threshold value or a signal quality parameter of the service data is lower than a set signal quality parameter threshold value for a continuously set number of times, it is indicated that the signal transmission performance of the corresponding service data is relatively poor, in order to ensure stable transmission of the corresponding service data and improve the signal quality of the service data, the method correspondingly modifies the data hopping link, and transmits the corresponding service data using the.
In one embodiment, no matter each terminal of the internet of things uploads the service data of the terminal or uploads the service data summarized by the lower node, 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, 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. Referring to the manner of performing classification of the internet of things terminal and correspondingly constructing the data hopping link based on the signal test in the steps S110 to S120, in the embodiment of the present application, the signal test of the internet of things terminal and the internet of things gateway is performed periodically, and whether to perform re-classification of the internet of things terminal is determined according to a signal test result. 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.
Referring to fig. 5, in the embodiment of the application, each internet of things terminal sends a test signal to the corresponding internet of things gateway, the internet of things gateway determines a corresponding signal quality parameter based on the test signal, classifies each internet of things terminal according to the signal quality parameter, determines a corresponding first-level internet of things terminal, a corresponding second-level internet of things terminal and a corresponding third-level internet of things terminal, constructs a corresponding data hopping link based on the first-level internet of things terminal, the second-level internet of things terminal and the third-level internet of things terminal, sends the data hopping link to each corresponding internet of things terminal, each internet of things terminal performs service data transmission based on the corresponding data hopping link when service data is uploaded, summarizes signal quality parameter detection results or error rate detection results when the second-level internet of things terminal, the first-level internet of things terminal and the internet of things, and modifying the corresponding data hopping transmission link based on the corresponding signal quality parameter detection result or the error rate detection result. By adopting the technical means, a data hopping transmission link can be constructed, and the signal transmission quality can be guaranteed in real time. And the real-time signal transmission performance is detected and modified to further ensure the real-time transmission performance of the signal.
