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 skip-transmission selection method for an internet of things terminal according to an embodiment of the present disclosure, where the data skip-transmission selection method for the internet of things terminal provided in this embodiment may be executed by a data skip-transmission selection device for the internet of things terminal, the data skip-transmission selection device for the internet of things terminal may be implemented in a software and/or hardware manner, and the data skip-transmission selection device for the internet of things terminal may be formed by two or more physical entities or may be formed by one physical entity. Generally, the data hopping selection device of the terminal of the internet of things can be the 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 data skip selection method of an internet of things terminal. Referring to fig. 1, the data skip-transmission selection method for the internet of things terminal 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 gateway of the Internet of things receives a plurality of test signal copies corresponding to one test signal through multi-antenna diversity, and performs signal diversity combining based on the test signal copies to obtain combined signals corresponding to the test signals;
s130, determining corresponding signal quality parameters based on the combined signals, classifying each Internet of things terminal according to the signal quality parameters, determining a corresponding first-level Internet of things terminal and a corresponding second-level Internet of things terminal, and sending corresponding terminal classification information to the first-level Internet of things terminal and the second-level Internet of things terminal.
The data skip-transmission selection method for the internet of things terminal aims to determine the signal quality of each internet of things terminal and an internet of things gateway through signal testing, and then performs internet of things terminal classification according to the signal quality to generate terminal classification information. And each Internet of things terminal selects superior equipment to jump-transmit the service data according to the terminal grading information so as to ensure the high-quality transmission of the service data and optimize the system service operation.
The Internet of things system comprises a plurality of Internet of things terminals and Internet of things gateways subordinate to the Internet of things terminals, wherein the Internet of things terminals are distributed at all positions in the 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. Therefore, the test signals are sent to the Internet of things gateway through the Internet of things terminals to carry out signal test, and the Internet of things terminals are classified based on the signal test results.
For example, referring to fig. 2, a schematic structural diagram of an internet of things gateway according to an embodiment of the present application is provided, where the internet of things gateway is provided with N diversity antennas and corresponding receivers, and each antenna and corresponding receiver are used for receiving a signal 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 respective diversity signals and combining the diversity signals, so as to implement signal diversity reception and combination of the internet of things gateway. 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 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, in the embodiment of the present application, a combined signal is obtained through diversity combining of the test signal copies, and then a corresponding signal quality parameter is determined based on the combined signal. The method comprises the steps of determining each test signal copy corresponding to a combined signal, measuring and calculating initial signal quality parameters of each test signal copy, and calculating the mean value of each initial signal quality parameter to obtain the signal quality parameters corresponding to the combined signal. In particular, the initial signal quality parameter value of the test signal replica is determined by the signal reception power, signal reception strength, channel instantaneous quality value and/or 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. The various types of parameters are measured by the corresponding test signal copies and antenna parameters. Further, in order to quantize the initial signal quality parameter value, a calculation formula of the initial signal quality parameter value is provided to quantize the signal quality of the test signal replica, and the calculation formula of the initial signal quality parameter value is:
f＝ω1P+ω2d1+ω3h+ω4d2
where f is the initial signal quality parameter value, P is the 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 actual influences of various types of parameters on the initial signal quality parameter values. Based on the initial signal quality parameter value calculation formula, the initial signal quality parameter value of each test signal copy 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 copy, and a corresponding quantization formula is set accordingly. The above formula is only one calculation method for calculating the initial 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. Further, based on the determined initial signal quality parameters of the past test signal copies, the embodiment of the present application calculates the average value by overlapping the initial signal quality parameters as the average valueThe signal quality parameters of the combined signal. It can be understood that the higher the signal quality parameter, the better the signal transmission performance.
Furthermore, in one embodiment, the corresponding signal quality parameter may also be determined from the plurality of combined signals by extracting a combined signal corresponding to the plurality of test signals. The signal quality parameters are determined through the plurality of combined signals, so that the condition that the test result is accidental due to a single 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 combined signals, and a mean value is obtained according to each signal quality parameter 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 signal quality parameter threshold, if the signal quality parameter of the corresponding internet of things terminal reaches the signal quality parameter threshold, the signal transmission performance of the internet of things terminal and the internet of things gateway is considered to be relatively good, and the part of the internet of things terminals are set as first-level internet of things terminals. On the contrary, if the signal quality parameter of the corresponding internet of things terminal is lower than the signal quality parameter threshold value, the signal transmission performance of the internet of things terminal and the internet of things gateway is considered to be relatively poor, the part of the internet of things terminals are set as second-level internet of things terminals, so that the classification of each internet of things terminal of the gateway can be realized, corresponding terminal classification information is generated according to the classification result, and the terminal classification information is sent to each corresponding internet of things terminal. The terminal grading information marks grading results of the terminals of the Internet of things and is used for informing the grading of the terminals of the Internet of things, so that the terminals of the Internet of things can determine to select another terminal of the Internet of things according to the grading of the terminals of the Internet of things to carry out service data skip transmission or directly upload service data to the gateway of the Internet of things.
S140, each secondary Internet of things terminal selects one primary Internet of things terminal to jump over service data in a set region range of the secondary Internet of things terminal based on the terminal grading information;
s150, the first-level Internet of things terminals gather service data of the first-level Internet of things terminals and service data jumped by the second-level Internet of things terminals correspondingly, and the service data are uploaded to the Internet of things gateway.
Furthermore, each internet of things terminal can determine the grade of the terminal based on the terminal grading information sent by the internet of things gateway, and service data is transmitted based on the grade of the terminal when the terminal enters the station. The second-level internet of things terminal is corresponding to the first-level internet of things terminal, and because the signal transmission performance between the second-level internet of things terminal and the internet of things gateway is relatively poor, the first-level internet of things terminal with relatively good signal transmission performance needs to be selected as a communication relay, and service data is skipped to the first-level internet of things terminal, so that the service data can be better collected to the internet of things gateway through the first-level internet of things terminal. And the second-level Internet of things terminal selects the first-level Internet of things terminal within a set range of the second-level Internet of things terminal. It can be understood that the signal transmission performance of the second-level internet of things terminal and the first-level internet of things terminal in the set range of the second-level internet of things terminal is relatively good, and service data can be subjected to skip transmission well by selecting one first-level internet of things terminal in the range. Preferably, the second-level internet of things terminal can select the first-level internet of things terminal closest to the second-level internet of things terminal within the set range as a communication relay to hop over the service data.
Referring to fig. 3, each secondary internet of things terminal 13 selects a corresponding primary internet of things terminal 12 as a communication relay based on the service data skip transmission mode, and skips the service data to the corresponding primary internet of things terminal 12. Further, after the first-level internet of things terminal 12 collects the service data jumped by the second-level internet of things terminal 13, the service data of the first-level internet of things terminal and the service data jumped by the second-level internet of things terminal 13 are uploaded to the internet of things gateway 11, so that the service data uploading of the internet of things terminals and the internet of things gateway is completed. Similarly, when the service data is issued, the internet of things gateway issues the service data step by step according to the internet of things terminal, so that service data interaction between the internet of things terminal and the internet of things gateway is completed.
In one embodiment, the first-level internet of things terminal further performs a skip transmission reselection process of the second-level internet of things terminal according to the error rate in the service data transmission process. Wherein, the jump reselection process comprises:
s1501, the first-level Internet of things terminal carries out error rate detection on the basis of the service data jumped by the corresponding second-level Internet of things terminal, and corresponding error rate information is determined;
s1502, if the error rate information reaches a set error rate threshold value, feeding back a skip transmission reselection prompt to the corresponding secondary Internet of things terminal, wherein the skip transmission reselection prompt is used for indicating the corresponding secondary Internet of things terminal to select one primary Internet of things terminal to skip transmission service data within a set region range of the secondary Internet of things terminal.
Specifically, the first-level internet of things terminal performs error rate detection on the service data uploaded by the corresponding second-level internet of things terminal, and the signal transmission performance between the first-level internet of things terminal and the corresponding second-level internet of things terminal is judged according to the error rate detection result. It can be understood that, if the error rate information reaches the set error rate threshold, it indicates that the signal transmission performance between the terminal and the corresponding second-level internet of things is relatively poor, so as to ensure stable transmission of service data of the corresponding second-level internet of things terminal and improve the service data transmission performance. And issuing a corresponding skip transmission reselection prompt to a corresponding second-level Internet of things terminal through the first-level Internet of things terminal. And indicating the terminal to select another first-level Internet of things terminal to jump over the service data within the set region range of the terminal. Therefore, the signal quality of the service data finally sent to the gateway of the Internet of things is relatively good, and the situation that the signal quality is influenced by data skipping is avoided.
On the other hand, in one embodiment, the first-level internet of things terminal may further perform a data retransmission process of the second-level internet of things terminal according to the error rate in the service data transmission process. Wherein, the data retransmission process comprises:
s1503, the first-level Internet of things terminal carries out error rate detection on the basis of the service data jumped by the corresponding second-level Internet of things terminal, and determines corresponding first error rate information;
s1504, if the first error rate information reaches a set error rate threshold value, feeding back a first retransmission prompt to the corresponding second-level Internet of things terminal, wherein the first retransmission prompt is used for indicating the corresponding second-level Internet of things terminal to retransmit the service data.
Specifically, the first-level internet of things terminal performs error rate detection on the service data uploaded by the corresponding second-level internet of things terminal, and the signal transmission performance between the first-level internet of things terminal and the corresponding second-level internet of things terminal is judged according to the error rate detection result. It can be understood that, if the error rate information reaches the set error rate threshold, it indicates that the signal transmission performance between the terminal and the corresponding second-level internet of things is relatively poor, so as to ensure stable transmission of service data of the corresponding second-level internet of things terminal and improve the signal quality of the service data. And issuing a corresponding retransmission prompt to a corresponding second-level Internet of things terminal through the first-level Internet of things terminal. Instructing it to re-hop the traffic data. Therefore, the signal quality of the service data finally sent to the gateway of the Internet of things is relatively good, and the service operation processing of the system of the Internet of things is prevented from being influenced by the quality of the service data.
In addition, in one embodiment, the error rate detection is also performed on the service data received by the internet of things gateway and sent by each first-level internet of things terminal, and the data retransmission process of the first-level internet of things terminal is performed according to the detection result. Wherein, the data retransmission process comprises:
s1505, the Internet of things gateway performs error rate detection based on the service data uploaded by each first-level Internet of things terminal, and determines corresponding second error rate information;
and S1506, if the second error rate information reaches a set error rate threshold, feeding back a second retransmission prompt to the corresponding first-level Internet of things terminal, wherein the second retransmission prompt is used for indicating the corresponding first-level Internet of things terminal to retransmit the service data.
Specifically, the internet of things gateway performs error rate detection on the service data uploaded by the corresponding first-level internet of things terminal, and judges the signal transmission performance between the gateway and the corresponding first-level internet of things terminal according to an error rate detection result. It can be understood that, if the error rate information reaches the set error rate threshold, it indicates that the signal transmission performance between the terminal and the corresponding first-level internet of things is relatively poor, so as to ensure stable transmission of the service data of the corresponding first-level internet of things terminal and improve the signal quality of the service data. And issuing a corresponding retransmission prompt to a corresponding first-level Internet of things terminal through the Internet of things gateway. Instructing it to re-upload the traffic data. Therefore, the signal quality of the service data sent to the gateway of the Internet of things on the corresponding first-level terminal of the Internet of things is relatively good, and the service operation processing of the Internet of things system is prevented from being influenced by the quality of the service data.
Further, the internet of things gateway performs error rate detection on the service data uploaded by one first-level internet of things terminal each time, and when the second error rate information reaches a set error rate threshold value after the internet of things gateway detects the second error rate information for a continuous set number of times, the corresponding first-level internet of things terminal is graded again. It can be understood that, if the error rate of the service data uploaded for multiple times by the corresponding first-level internet of things terminal is relatively high (that is, a set error rate threshold is reached), it indicates that the signal transmission performance of the first-level internet of things terminal and the internet of things gateway is in a poor state for a long time, and at this time, the first-level internet of things terminal is classified into the second-level internet of things terminal through re-classification, so that the first-level internet of things terminal is selected within a self-set range to skip the service data, thereby ensuring the signal quality of the uploaded service data and optimizing the service data transmission of the system.
In one embodiment, each secondary 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 upgrade the corresponding secondary internet of things terminal or not based on the test signal. Considering that the signal transmission performance of each internet of things terminal may be different at different time nodes. Therefore, in the embodiment of the application, the signal test of the second-level internet of things terminal is performed every other set period, the signal quality parameters corresponding to the second-level internet of things terminal are determined by referring to the signal test modes of the steps S110 to S130, and whether the second-level internet of things terminal is upgraded or not is judged according to the comparison of the signal quality parameters. It can be understood that if the signal quality parameter of the second-level internet-of-things terminal reaches the 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 efficiency.
