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 gateway switching and binding method for an internet of things terminal according to an embodiment of the present invention, where the gateway switching and binding method for an internet of things terminal provided in this embodiment may be executed by a gateway switching and binding device for an internet of things terminal, the gateway switching and binding device for an internet of things terminal may be implemented in a software and/or hardware manner, and the gateway switching and binding device for an internet of things terminal may be formed by two or more physical entities or may be formed by one physical entity. Generally, the gateway switching and binding device of the terminal of the internet of things can be a system of the internet of things.
The following description will be given by taking an internet of things system as an example of a main body for executing a gateway switching and binding method of an internet of things terminal. Referring to fig. 1, the gateway switching and binding method for the terminal of the internet of things specifically includes:
s110, each Internet of things gateway receives one or more test signals broadcast by the same Internet of things terminal, determines signal transmission quality information of the test signals, collects the signal transmission quality information to a cloud end, and generates a signal transmission quality list of each Internet of things gateway corresponding to the Internet of things terminal.
The gateway switching and binding method of the Internet of things terminal aims to determine the Internet of things gateway with the best signal transmission performance with the Internet of things terminal through signal testing, then the Internet of things terminal is bound with the Internet of things gateway, and then the subsequent Internet of things terminal conducts signal transmission with the Internet of things gateway as a communication relay and a cloud end to conduct related services of an Internet of things system. And when the binding relationship is established, corresponding session keys are further configured for the two, so that the safety of signal transmission between the two is ensured.
Specifically, the internet of things system of the embodiment of the application comprises a cloud end, a plurality of internet of things gateways and a plurality of internet of things terminals, and each internet of things terminal selects the internet of things gateway to bind according to signal testing, and then performs signal transmission. It can be understood that, generally speaking, an internet of things terminal may include a plurality of internet of things gateways in a communication range, and in order to optimize a signal transmission effect and reduce an influence of signal attenuation, the internet of things terminal needs to select an internet of things gateway with the best signal transmission performance from the plurality of internet of things gateways through a signal test to bind, so as to provide a better signal transmission effect. When signal testing is performed, referring to fig. 2, in the embodiment of the application, the test signal is broadcasted by the internet of things terminal 11 in the communication range, correspondingly, all the internet of things gateways 12 in the communication range of the internet of things terminal 11 can receive the test signal, further process the test signal, measure and calculate signal transmission quality information, and upload the signal transmission quality information to the cloud end 13, so that the cloud end 13 selects one internet of things gateway 12 from the plurality of internet of things gateways 12 according to the signal transmission quality information to bind the internet of things terminal 11.
And corresponding to each Internet of things gateway, after receiving the test signals sent by the same Internet of things terminal, representing the signal transmission performance between the gateway and the Internet of things terminal by measuring and calculating the signal transmission quality information of each test signal according to the signal transmission quality information. The signal transmission quality information 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 diversity antenna. Wherein the channel instantaneous quality value represents the channel quality, channel matrix feedback, signal response and/or interference information for the corresponding diversity antenna. And measuring the various types of parameters through the corresponding test signals and the antenna parameters. Further, in order to quantize the signal transmission quality information, a calculation formula of the signal transmission quality information is provided to quantize the signal quality of the test signal, and the calculation formula of the signal transmission quality information is:
f＝ω1P+ω2d1+ω3h+ω4d2
where f is signal transmission quality information, P is signal reception power, and 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 actual influence of various types of parameters on signal transmission quality information. Based on the signal transmission quality information calculation formula, the signal transmission quality information 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 transmission quality information according to 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.
Further, signal transmission quality information determined based on each internet of things gateway is uploaded to a cloud end, the signal transmission quality information is collected through the cloud end, a signal transmission quality list is constructed based on the signal transmission quality information, and the signal transmission quality list represents the signal transmission performance of the internet of things terminal and among the internet of things gateways. It can be understood that the larger the value of the signal transmission quality information is, the better the signal transmission performance of the internet of things gateway and the corresponding internet of things terminal is.
In one embodiment, based on the constructed signal transmission quality list, the cloud updates the signal transmission quality list according to the corresponding signal transmission quality information reported by each internet of things gateway every other set period. It can be understood that, in order to ensure that the test of the signal transmission quality information has real-time performance, the signal transmission quality list can visually represent the signal transmission quality information in the recent period of time, and by updating the signal transmission quality list in real time, the accuracy of the construction of the binding relationship can be ensured, and the service data transmission effect between the terminal of the internet of things and the gateway of the corresponding internet of things is optimized.
It should be noted that, when the gateway of the internet of things measures and calculates the signal transmission quality information according to the test signal, the gateway of the internet of things may also measure and calculate the signal transmission quality information according to the plurality of test signals by extracting the corresponding plurality of test signals, so as to avoid the accidental situation of the test result caused by a single test signal, and ensure that the test result is stable and effective. Specifically, signal transmission quality information is calculated through a plurality of test signals, and an average value is obtained according to the value of each signal transmission quality information, so that final signal transmission quality information is obtained.
S120, the cloud terminal selects one Internet of things gateway as a first communication relay of the Internet of things terminal and the cloud terminal based on the signal transmission quality list, a first binding relationship between the first communication relay and the Internet of things terminal is established, a corresponding first session key is configured for the binding relationship, the first binding relationship and the first session key are issued to the first communication relay, the first communication relay forwards the first binding relationship and the first session key to the Internet of things terminal, and the first communication relay and the Internet of things terminal perform service data transmission based on the first binding relationship and the first session key.
Further, based on the signal transmission quality list determined in step S110, the cloud selects a corresponding internet of things gateway with optimal signal transmission quality information from the signal transmission quality list as a communication relay between the corresponding internet of things terminal and the cloud, and defines the communication relay as a first communication relay. And further constructing a binding relationship between the first communication relay and the Internet of things terminal, wherein the binding relationship is used for indicating that the Internet of things terminal is bound with the first communication relay. Referring to fig. 3, based on the binding relationship, the related service data of the subsequent internet of things terminal 11 is uploaded to the internet of things gateway 12 selected as the first communication relay, and is uploaded to the cloud 13 by the first communication relay. Similarly, based on the binding relationship, the cloud 13 also forwards the relevant information to the internet of things terminal 11 through the first communication relay when the relevant information needs to be sent. Specifically, the binding relationship includes I P information of the first communication relay and the terminal of the internet of things, so that the first communication relay and the terminal of the internet of things can clearly identify I P addresses of each other, and accordingly data communication is performed. In addition, while the binding relationship is sent, the first communication relay and the first session key of the terminal of the internet of things are synchronously sent to the first communication relay, and the first session key is transmitted to the terminal of the internet of things by the first communication relay. When the subsequent first communication relay and the terminal of the Internet of things transmit signals, the encryption key of the first session key is used for encrypting and transmitting the signals, and the decryption key is used for decrypting the signals corresponding to the signal receiving end, so that the encryption transmission of the signals is realized, and the safety of the signal transmission is guaranteed.
In one embodiment, for the internet of things gateway which is not bound with the internet of things terminal, in order to save energy consumption of the internet of things system, the part of the internet of things gateway is controlled to be in periodic dormancy, so that system energy consumption management is optimized. Referring to fig. 4, the process of selecting the internet of things gateway dormancy includes:
s121, the cloud end counts the first binding relations, and determines the binding number of the Internet of things terminals bound by the Internet of things gateways;
and S122, periodically sleeping the Internet of things gateway which is not bound with the Internet of things terminal based on the binding quantity.
Specifically, based on a first binding relationship which is constructed in advance, the cloud end can determine the binding number of the internet of things terminals bound by the internet of things gateways by counting the binding relationship between the internet of things terminals and the internet of things gateways. If the binding number of a certain internet of things gateway is zero, the fact that the internet of things gateway does not serve as a communication relay to transmit service data currently is indicated, and at the moment, the part of the internet of things gateway is dormant periodically, so that the energy consumption of the part of the internet of things gateway can be saved, and the energy consumption management of the system is optimized.
In addition, in order to further save the energy consumption of the system, based on the counted binding number of the internet of things gateways, the internet of things gateways of which the binding number is lower than a set number threshold are determined to be used as dormant gateways, communication relays are reselected for the internet of things terminals bound with the dormant gateways, and the dormant gateways are dormant periodically. It can be understood that if the number of the internet of things terminals bound by one internet of things gateway is small (that is, lower than a set number threshold), communication relays can be reselected for the internet of things terminals bound by the part of internet of things gateways, and the part of internet of things gateways are set to sleep periodically, so that the energy consumption management of the system is further optimized.
In addition, in an embodiment, the cloud sends the new first session key to the first communication relay every other preset security management period, and the first communication relay forwards the new first session key to the internet of things terminal to update the first session key. Specifically, the first session key is periodically updated, so that the signal transmission safety between the terminal of the internet of things and the first communication relay can be further guaranteed, the difficulty of signal breaking is increased, the problems of information stealing, embezzlement and the like can be effectively avoided, and the signal transmission effect is optimized.
S130, when the communication abnormality between the cloud and the first communication relay is detected, the cloud reselects one Internet of things gateway as a second communication relay of the Internet of things terminal based on the signal transmission quality list to construct a second binding relationship, configures a corresponding second session key, issues the second binding relationship and the second session key to the second communication relay, and forwards the second binding relationship and the second session key to the Internet of things terminal through the second communication relay, so that the second communication relay and the Internet of things terminal perform service data transmission based on the second binding relationship and the second session key.
After that, the internet of things terminal transmits service data with the cloud end through the first communication relay, the cloud end detects whether the first communication relay is abnormal in communication or not in real time when the cloud end transmits page number data with the first communication relay, and the internet of things terminal communication relay is reselected based on an abnormal detection result. And carrying out error rate detection according to the service data uploaded to the cloud end by the first communication relay, and judging whether the first communication relay is abnormal in communication or not based on an error rate detection result. It can be understood that, if it is detected that the error rate of the current service data is higher than the set error rate threshold, it is considered that the error rate of the current service data is too high, and the first communication relay is abnormal in communication, and a communication relay needs to be selected for the corresponding internet of things terminal again.
Referring to fig. 5, when a communication abnormality occurs in one of the internet of things gateways 12 and the cloud 13 that are selected as the first communication relay, the cloud 13 queries the signal transmission quality list, reselects one of the internet of things gateways (except the first communication relay) with the largest signal transmission quality information from the signal transmission quality list as the second communication relay of the internet of things terminal, constructs a second binding relationship, configures a corresponding second session key, issues the second binding relationship and the second session key to the second communication relay, and forwards the second binding relationship and the second session key to the internet of things terminal through the second communication relay, so that the second communication relay and the internet of things terminal perform service data transmission based on the second binding relationship and the second session key. It can be understood that, according to the established second binding relationship, the cloud end can unbind the original first binding relationship of the internet of things terminal, so as to avoid the condition that service data transmission is disordered.
Further, when the internet of things terminal transmits service data through a second relay and a cloud, and when the fact that the communication between the cloud and the second communication relay is abnormal is detected, the communication relay is reselected for the corresponding internet of things terminal. Referring to the selection mode of the second communication relay, the embodiment of the application reselects the communication relay for service data transmission for the terminal of the internet of things. In some embodiments, if the communication link between the original first communication relay and the cloud returns to normal, the cloud may select the original first communication relay to be bound with the internet of things terminal again, so that the selection efficiency of the communication relay may be increased, and the transmission quality of the service data may be guaranteed.
Referring to fig. 6, receiving one or more test signals broadcast by the same internet of things terminal through each internet of things gateway, determining signal transmission quality information of the test signals, summarizing the signal transmission quality information to a cloud, and generating a signal transmission quality list of the internet of things terminal corresponding to each internet of things gateway; the method comprises the steps that the cloud terminal selects an Internet of things gateway as a first communication relay of the Internet of things terminal and the cloud terminal based on a signal transmission quality list, a first binding relation between the first communication relay and the Internet of things terminal is established, a corresponding first session key is configured for the binding relation, the first binding relation and the first session key are issued to the first communication relay, the first binding relation and the first session key are forwarded to the Internet of things terminal by the first communication relay, and the first communication relay and the Internet of things terminal perform service data transmission based on the first binding relation and the first session key; when the communication abnormality between the cloud and the first communication relay is detected, the cloud reselects one Internet of things gateway as a second communication relay of the Internet of things terminal based on the signal transmission quality list, a second binding relationship is established, a corresponding second session key is configured, the second binding relationship and the second session key are issued to the second communication relay, and the second binding relationship and the second session key are forwarded to the Internet of things terminal by the second communication relay, so that the second communication relay and the Internet of things terminal perform service data transmission based on the second binding relationship and the second session key. And updating the session key by setting a period, and updating the signal transmission quality list by setting the period so as to ensure the real-time performance of data. By adopting the technical means, the signal transmission effect of the Internet of things system can be optimized, and the signal transmission safety and the signal transmission performance between the terminal of the Internet of things and the gateway can be guaranteed.
