[0017] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0018] The embodiments of the present application disclose a communication device reliability assessment method and system.

[0019] Example: Figure 1 As shown, the present invention provides a communication device reliability assessment method, comprising: S100, obtaining an evaluation space of the communication device, and constructing an evaluation model based on the evaluation space; the evaluation model includes a first receiver and a second receiver; since the evaluation space is limited, and the actual evaluation demand is greater than the evaluation space, it is necessary to set the evaluation module in the evaluation space so that the results obtained by the evaluation module can be more consistent with the actual results, thereby improving the accuracy of the evaluation results.

[0020] S200, the communication device to be evaluated outputs the built-in original data to obtain initial data, the first receiver receives the initial data and records the initial data to obtain first transfer information, the second receiver receives the initial data and records the initial data to obtain second transfer information; wherein, the first transfer information and the second transfer information both include signal strength and received data. In the initial state, the communication device to be evaluated outputs the original data, the first receiver receives the initial data output by the communication device to be evaluated, thereby determining the received data of the initial data and the signal strength of the initial data when receiving, thereby obtaining new data information, namely the first transfer information, and outputs the first transfer information to the communication device to be evaluated to clarify the output data of the communication device to be evaluated in the next cycle and the signal strength when outputting. Similarly, the second receiver receives the initial data and records the corresponding received data and signal strength to obtain the second transfer information.

[0021] S300, obtaining the evaluation distance requirement in the evaluation requirement, and calculating the ratio of the evaluation distance requirement and the distance data between the communication device to be evaluated and the first receiver in the evaluation model to obtain the minimum cycle amount; by calculating the minimum cycle amount, not only can the transmission distance of the output signal of the communication device to be evaluated effectively meet the evaluation distance requirement, thereby making the evaluation result more accurate, but also by calculating the minimum cycle amount, the amount of data that needs to be analyzed is clarified, data redundancy is avoided, and the operation speed is improved.

[0022] S400, the communication device to be evaluated outputs the received data in the first transfer information according to the signal strength in the first transfer information, until the number of data outputs by the communication device to be evaluated is equal to the minimum cycle amount; for example: the communication device to be evaluated outputs the original data, the first receiver receives the output signal and records it as signal A1, in the second cycle, the communication device to be evaluated outputs the data in signal A1 according to the signal strength of signal A1, the first receiver receives the output signal and records it as signal A2, and so on, until the number of cycles of the communication device to be evaluated is equal to the minimum cycle amount.

[0023] S500, based on the minimum cycle amount, the first receiver and the second receiver receive the output signal output by the communication device to be evaluated in each cycle, and obtain the first transfer information set and the second transfer information set; since the information transmission distance of the evaluation space is limited, it is necessary to transfer the information multiple times so that the transmission distance of the information can meet the evaluation distance requirement, thereby making the obtained data volume more authentic, thereby improving the accuracy of the evaluation results.

[0024] S600, comprehensively judge the first transfer information set and the second transfer information set to determine whether the data output of the communication device to be evaluated is stable; by performing multiple data cycles on the data output of the communication device to be evaluated, the workload of the communication device to be evaluated is increased, and the stability of the long-term operation of the communication device to be evaluated can be judged while performing long-distance signal propagation evaluation on the communication device to be evaluated, thereby improving the accuracy of the comprehensive evaluation of the communication device to be evaluated.

[0025] S700, if it is determined that the data output of the communication device to be evaluated is stable, then the data analysis is performed on the first transfer information set and the second transfer information set with stability to determine the relationship between the data loss amount, signal strength and transmission distance, and recorded as relationship data; when it is determined that the output signal of the communication device to be evaluated is stable, the attenuation of the same signal output strength at different transmission distances is judged on the first transfer information set and the second transfer information set with stability, and the relationship between the attenuation of different signal output strengths and the data loss amount is judged, so as to clarify the remaining signal strength after data is transmitted for a certain distance under a certain signal output strength, and then judge the data loss amount under this transmission distance according to the signal strength difference. For example, the relationship obtained: the relationship between signal strength and transmission distance is y=z-ax, where x is the transmission distance, a is the proportionality coefficient, z is the initial signal strength, and y is the signal strength at the transmission distance x. The relationship between the signal strength difference and the data loss amount is T=mn, where T is the loss amount, m is the signal strength difference, and n is the proportionality coefficient.

[0026] S800, obtaining the evaluation requirements of the communication device to be evaluated, and evaluating the communication device to be evaluated according to the evaluation requirements and the relationship data, obtaining and outputting the evaluation result of the communication device to be evaluated. After determining the relationship between the data loss amount, signal strength and transmission distance in the communication device to be evaluated, by obtaining the actual evaluation requirements, it is determined whether the communication device to be evaluated can operate safely under the evaluation requirements. If it can operate safely, the evaluation result is output as qualified, and if it cannot operate safely, the evaluation result is output as unqualified.

[0027] In the present embodiment, by determining the evaluation space of the communication device to be evaluated and planning the evaluation space, the test result of the communication device to be evaluated is consistent with the effect of the actual communication device to be evaluated in the application. By utilizing the communication device to be evaluated to perform multiple transmissions of the same output signal with different signal strengths, and evaluating and analyzing the results of the multiple transmissions, a judgment is made on the stability of the communication device to be evaluated after the multiple transmissions, so as to ensure the validity and accuracy of the collected data. When it is determined that the communication device to be evaluated can remain stable under the evaluation requirements, the relationship between the data loss amount, the signal strength and the transmission distance is determined, so that the result obtained when the satisfaction judgment of the communication device to be evaluated is made according to the evaluation requirements is more credible, thereby improving the evaluation result.

[0028] In step S100, an evaluation space of a communication device is obtained, and an evaluation model is constructed based on the evaluation space, including the following steps: S110, obtaining an evaluation space of the communication device, and obtaining a distance value between any two positions in the evaluation space according to the evaluation space; S120, screening the distance values ​​between any two positions in the evaluation space, marking the two positions with the largest distance values ​​as the first placement position and the second placement position, and marking the center position of the first placement position and the second placement position as the center point position; S130, setting up a communication device to be tested at a first placement position, setting up a first receiver at a center point position, and setting up a second receiver at a second placement position.

[0029] In this embodiment, by obtaining the maximum distance value in the evaluation space, the actual distance of signal transmission is longer when the communication device to be evaluated outputs a signal, thereby making the impact of the environment on the signal more real and effective, thereby improving the accuracy of the evaluation result when evaluating the communication device to be evaluated. By selecting a double distance relationship between the first receiver and the second receiver, when analyzing the data relationship between the first receiver and the second receiver, the variables are controlled due to the multiple relationship of the distance data, thereby making the analysis process more concise and improving the analysis efficiency.

[0030] In step S600, a comprehensive judgment is made on the first transfer information set and the second transfer information set to determine whether the data output of the communication device to be evaluated is stable, including the following steps: S610, based on the time data, comparing the first transfer information and the second transfer information obtained in the first cycle with the original data; S620, if the first transfer information and the second transfer information obtained in the first cycle are the same as the original data, then the signal strength of the initial data in the first cycle is not analyzed; S630, if the first transfer information in the first cycle is the same as the original data, and the second transfer information is different from the original data, the second transfer information is compared with the first transfer information to obtain the first data loss amount; for example, the first transfer information obtained in the first cycle is a, the original data is z, and the second transfer information obtained in the first cycle is b, then the first data loss amount is ba.

[0031] S640, obtaining the first transfer information obtained in the second cycle, and comparing the first transfer information obtained in the second cycle with the first transfer information obtained in the first cycle to obtain a second data loss amount; for example, if the first transfer information in the second cycle is c, then the second data loss amount is ca.

[0032] S650, comparing the first data loss amount with the second data loss amount to obtain a first comparison relationship; S660, if the first comparison relationship is that the first data loss amount is less than the second data loss amount, it is determined that the data transmission function of the communication device to be evaluated is not stable, and a corresponding evaluation report is output; for example, by comparing the numerical values ​​of the first data loss amount ba and the second data loss amount ca, the comparison relationship is determined.

[0033] S670, if the first comparison relationship is that the first data loss amount is greater than or equal to the second data loss amount, then obtain the first transfer information obtained in the third cycle, mark the data loss amount between the first transfer information obtained in the third cycle and the first transfer information obtained in the second cycle as the third data loss amount, mark the data loss amount between the first transfer information obtained in the second cycle and the second transfer information obtained in the second cycle as the fourth data loss amount, and compare the third data loss amount with the fourth data loss amount to obtain a second comparison relationship; for example, if the second transfer information in the second cycle is d, then the data loss amount between the first transfer information c and the second transfer information d in the second cycle is dc, and the loss amount is marked as the third data loss amount, and the first transfer information in the third cycle is e, then the data loss amount between the first transfer information e in the third cycle and the first transfer information c in the second cycle is ec, that is, the fourth data loss amount, so dc and ec are compared in numerical value to determine the comparison relationship.

[0034] S680: If the second comparison relationship is the same as the first comparison relationship, it is determined that the communication device to be evaluated has stability in the cycle, and the second cycle is marked until all the built-in cycle quantities are marked.

[0035] In this embodiment, when judging the stability of the communication device to be evaluated in a certain cycle number, the data loss amount among the communication device to be evaluated, the data on the first receiver and the second receiver at two cycle numbers adjacent to the cycle number is calculated, and then the data loss amounts at the two adjacent cycle numbers are compared accordingly to determine the corresponding comparison relationship, and then the comparison relationship is compared accordingly to determine whether the two comparison relationships are the same, so as to accurately judge the stability of the communication device to be evaluated in the cycle number, thereby ensuring the accuracy of the first transfer information and the second transfer information at the cycle number with stability, thereby making the relationship data judged based on the first transfer information and the second transfer information more accurate, thereby improving the accuracy of the evaluation result.

[0036] In step S700, if it is determined that the data output of the communication device to be evaluated is stable, data analysis is performed on the first transfer information set and the second transfer information set with stability to determine the relationship between the data loss amount, signal strength and transmission distance, and record them as relationship data, including the following steps: S710, based on the number of cycles, at the same number of cycles, the signal strength of the output signal of the communication device to be evaluated is calculated to be different from the signal strength in the first transfer information to obtain a first signal strength difference, and the signal strength of the output signal of the communication device to be evaluated is calculated to be different from the signal strength in the second transfer information to obtain a second signal strength difference; for example, in the same cycle, the signal strength of the communication device to be evaluated is a, the signal strength of the first transfer information is b, and the signal strength of the second transfer information is c, then the first signal strength difference is ba, and the second signal strength difference is ca.

[0037] S720, based on the first signal strength difference and the second signal strength difference, determine the relationship between the signal strength change and the transmission distance, and obtain a first strength relationship formula; for example, with the transmission distance as the horizontal coordinate and the signal strength as the vertical coordinate, the first signal strength difference and the second signal strength difference are two points on the coordinate axis, based on the theorem: two points determine a straight line, thereby obtaining a straight line formula passing through the two points.

[0038] S730, calculating the difference between the signal strength in the first transfer information and the signal strength in the second transfer information at the number of cycles to obtain a third signal strength difference; S740, obtaining the signal strength of the output signal of the communication device to be evaluated in the next cycle and the signal strength of the first transfer information in the corresponding number of cycles, and performing difference calculation to obtain a fourth signal strength difference; S750, calculate the ratio of the third signal strength difference and the fourth signal strength difference to obtain weighted data; because under the same output signal strength, the attenuation degree of the signal increases with the increase of the transmission distance, the attenuation increase relationship is determined by the third signal strength difference and the fourth signal strength difference, and then the straight line formula passing through the first signal strength difference and the second signal strength difference is corrected, and the straight line formula is continuously corrected according to the number of cycles, so that the final functional relationship can more accurately represent the relationship between the attenuation of the signal strength and the transmission distance.

[0039] S760, performing weighted processing on the first strength relationship equation based on the weighted data to obtain a relationship equation between the signal strength and the transmission distance, and recording the relationship equation as a first relationship equation; S770, performing difference calculation on the signal strength of the first transfer information and the signal strength of the second transfer information in two adjacent cycles and the signal strength of the output signal of the communication device to be evaluated in the corresponding cycle, to obtain the signal strength difference of the first transfer information and the signal strength difference of the second transfer information in the corresponding cycle; S780, performing difference calculation on the received data of the first transfer information and the received data of the second transfer information in the two adjacent cycles and the output data of the communication device to be evaluated in the corresponding cycle to obtain the data loss amount of the first transfer information and the data loss amount of the second transfer information in the corresponding cycle; S790, based on two adjacent cycles, establish a relationship between the signal strength difference of the first transfer signal and the data loss amount of the first transfer information to obtain a first data relationship formula, and establish a relationship between the signal strength difference of the second transfer information and the data loss amount of the second transfer information to obtain a second data relationship formula; S7100, determining a compensation amount between a data loss amount and a signal strength difference under the same transmission distance and the same output signal strength based on the first data relationship expression and the second data relationship expression; S7110, compensate the first data relationship equation based on the compensation amount to obtain a relationship equation between the signal strength difference and the data loss amount, and record it as a second relationship equation.

[0040] In this embodiment, when judging the relationship between signal strength and propagation distance, the signal attenuation at different transmission distances under the same cycle is judged to determine the relationship between signal attenuation and distance, and then the attenuation difference of the signal at the same transmission distance under different cycles is judged, so as to determine to continuously correct the determined relationship, so that the final correction result is consistent with the attenuation of the signal output by the actual communication device to be evaluated during the transmission process, thereby improving the relationship between the signal strength and the transmission distance of the communication device to be evaluated, and making the evaluation result of the reliability evaluation of the communication device to be evaluated according to the evaluation requirements more accurate.

[0041] When judging the relationship between signal strength and data loss, the signal strength difference and data loss between the first transfer information, the second transfer information and the communication device to be evaluated in each cycle are judged, so as to clarify the relationship between the signal strength difference and the data loss in each cycle, and then the data loss of each relational expression under the same signal strength is determined based on the relationship between the signal strength difference and the data loss in each cycle, and then the data loss of each relational expression is compensated and judged, and the data compensation amount is determined, and the relational expression under the corresponding cycle is compensated according to the data compensation amount, so that the data loss amount of the compensated relational expression under any signal strength is the same, thereby improving the accuracy of the judgment of the relationship between the signal attenuation degree of the device to be evaluated and the data loss amount.

[0042] A communication device reliability evaluation method further includes evaluating the information delay of the communication device to be evaluated, specifically: S1, obtaining the data output time of the communication device to be evaluated, the data receiving time of the first receiver, the data output time and the data receiving time of the second receiver in the same cycle; in one cycle, the first receiver receives the data output by the communication device to be evaluated, processes the data, and transmits the processed data to the communication device to be evaluated as the output data of the communication device to be evaluated when the next cycle is performed.

[0043] S2, obtaining the data output time of the communication device to be evaluated in the next cycle; S3, calculating the time difference between the data output time of the communication device to be evaluated in the same cycle and the data output time of the communication device to be evaluated in the next cycle to obtain first time data; S4, calculating the time difference between the data receiving time and the data output time of the first receiver in the same cycle to obtain second time data; S5, calculating the time difference between the data output time of the communication device to be evaluated and the data reception time of the second receiver in the same cycle to obtain third time data; S6, performing difference calculation on the first time data and the sum of the second time data and the third time data to obtain delay data.

[0044] In this embodiment, the data output time of the communication device to be evaluated, the data reception time of the first receiver, the data output time and the data reception time of the second receiver in each cycle are obtained, and the data output time of the communication device to be evaluated in adjacent cycles is calculated to determine the time consumed by the communication device to be evaluated when completing one cycle. Then, the data reception time and the data output time of the first receiver in the same cycle are calculated to obtain the data processing time when the first receiver receives the signal output by the communication device to be evaluated. Then, the data output time of the communication device to be evaluated and the data reception time of the second receiver in the same cycle are calculated to determine the time required for the communication device to be evaluated to transmit to the second receiver. The communication device to be evaluated is calculated to obtain the data processing time when the first receiver receives the signal output by the communication device to be evaluated. The time consumed in the first cycle includes the time required for the communication device to be evaluated to output to the first receiver, the data processing time of the first receiver, the time from the first receiver to the communication device to be evaluated, and the data processing time of the communication device to be evaluated. Since the sum of the transmission distances from the communication device to be evaluated to the first receiver and then from the first receiver to the communication device to be evaluated is the same as the transmission distance from the communication device to be evaluated to the second receiver, the sum of the time required for the communication device to be evaluated to output to the first receiver and the time from the first receiver to the communication device to be evaluated is equal to the time required for the communication device to be evaluated to transmit to the second receiver. The data processing time of the first receiver is known, so the data processing time of the communication device to be evaluated is obtained by performing difference calculation, and the data processing time is the delay time of the data processing of the communication device to be evaluated.

[0045] By utilizing the multiple relationship of the distances between the first receiver and the second receiver to the communication device to be evaluated, and then reading the data output time of the communication device to be evaluated, the data reception time of the first receiver, the data output time and the data reception time of the second receiver, and performing a difference calculation, the delay in data processing of the communication device to be evaluated can be judged quickly and effectively, thereby simplifying the judgment process and improving the judgment efficiency.

[0046] In step S800, obtaining the evaluation requirements of the communication device to be evaluated, and evaluating the communication device to be evaluated according to the evaluation requirements and the relationship data, obtaining and outputting the evaluation result of the communication device to be evaluated, includes the following steps: S810, obtaining an evaluation requirement of the communication device to be evaluated, and performing signal strength judgment on the first relationship according to the evaluation distance requirement in the evaluation requirement to determine the signal strength under the corresponding evaluation distance requirement; S820, determining a data loss amount of the communication device to be evaluated under the corresponding evaluation distance requirement based on the output signal strength of the communication device to be evaluated, the signal strength under the evaluation distance requirement, and the second relationship; S830, comparing the signal strength under the evaluation distance requirement, the data loss amount and the delay data of the communication device to be evaluated under the evaluation distance requirement based on the evaluation criteria in the evaluation requirement to determine whether the communication device to be evaluated meets the evaluation criteria; S840, if the evaluation criteria are met, the evaluation result is determined to be qualified and output; S850: If the evaluation criteria are not met, the evaluation result is determined to be unqualified and output.

[0047] In this embodiment, the requirements in the evaluation requirements are judged by using the first relationship and the second relationship to simulate the signal strength and data loss under the evaluation distance requirements, and then the simulated data is compared with the evaluation criteria in the evaluation requirements to determine the eligibility of the communication device to be evaluated.
