Technical Field

[0001] The present application relates to the field of communication system evaluation, and particularly to a method and system for evaluating the reliability of a communication device. Background Art

[0002] With the rapid development of communication technologies, communication devices are increasingly widely used in various fields, such as mobile communication, satellite communication, wireless sensor networks, etc. However, the reliability of communication devices is directly related to the stability of communication systems and the accuracy of data transmission. Especially for communication devices that perform long-distance transmission, how to accurately evaluate the reliability of communication devices has become an important research topic.

[0003] In related technologies, by using devices such as signal attenuators and interference generators to establish an analog long-distance transmission environment, various interferences and signal attenuation situations that may be encountered in the actual transmission process are simulated, and then the performance and reliability of the communication device under long-distance transmission conditions are evaluated in a smaller space.

[0004] In view of the above related technologies, only by establishing an analog transmission environment, in the actual transmission process, the transmission of signals is affected not only by the environment but also by the transmission distance itself. Therefore, there is a large deviation between the evaluation results obtained by the existing technologies when evaluating the reliability of communication devices and the actual situation, and the evaluation accuracy is low, and there is room for improvement.

[0062] The following will Figure 1 - Figure 2 make a further detailed description of this application.

[0063] This application embodiment discloses a communication device reliability evaluation method and system.

[0064] Embodiment: As Figure 1 shown, a communication device reliability evaluation method of the present invention includes:

[0065] S100, obtain the evaluation space of the communication device, and construct 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 requirements are greater than the evaluation space, it is necessary to set the evaluation module in the evaluation space, so that the result obtained by the evaluation module can be closer to the actual result, thereby improving the accuracy of the evaluation result.

[0066] In 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 data to obtain the first intermediate information. The second receiver receives the initial data and records the data to obtain the second intermediate information. Herein, both the first intermediate information and the second intermediate information 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 and signal strength of the initial data during reception, thus obtaining new data information, i.e., the first intermediate information, and outputting the first intermediate information to the communication device to be evaluated to clarify the output data and signal strength during output of the communication device to be evaluated in the next cycle. Similarly, the second receiver receives the initial data and records the corresponding received data and signal strength to obtain the second intermediate information.

[0067] In S300, obtain the evaluation distance requirement in the evaluation requirements, and calculate the ratio of the evaluation distance requirement to the distance data between the communication device to be evaluated and the first receiver in the evaluation model to obtain the minimum number of cycles. By calculating the minimum number of cycles, not only can the transmission distance of the output signal of the communication device to be evaluated effectively reach the evaluation distance requirement, thereby making the evaluation result more accurate, but also by calculating the minimum number of cycles, the amount of data to be analyzed is clarified, data redundancy is avoided, and the operation speed is improved.

[0068] In S400, the communication device to be evaluated outputs the received data in the first intermediate information according to the signal strength in the first intermediate information until the number of times of data output by the communication device to be evaluated is equal to the minimum number of cycles. For example: the communication device to be evaluated outputs the original data, and 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, and 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 number of cycles.

[0069] In S500, based on the minimum number of cycles, the first receiver and the second receiver receive the output signals output by the communication device to be evaluated in each cycle to obtain the first intermediate information set and the second intermediate information set. Since the information transmission distance in the evaluation space is limited, it is necessary to perform multiple intermediate transmissions on the information so that the information transmission distance can reach the evaluation distance requirement, thereby making the obtained amount of data more authentic and further improving the accuracy of the evaluation result.

[0070] S600, comprehensively judge the first intermediate information set and the second intermediate information set to determine whether the data output of the communication device to be evaluated is stable; by performing multiple data loops on the data output of the communication device to be evaluated, the workload of the communication device to be evaluated is increased, and thus the stability of the long-term operation of the communication device to be evaluated can be judged while evaluating the long-distance signal propagation of the communication device to be evaluated, thereby improving the accuracy of the comprehensive evaluation of the communication device to be evaluated.

[0071] S700, if it is determined that the data output of the communication device to be evaluated is stable, perform data analysis on the first intermediate information set and the second intermediate information set with stability to determine the relationship among the data loss amount, signal strength, and transmission distance, and record it as relationship data; when it is determined that the output signal of the communication device to be evaluated is stable, by judging the attenuation situation of the same signal output intensity at different transmission distances and the relationship between the attenuation amount of different signal output intensities and the data loss amount for the first intermediate information set and the second intermediate information set with stability, the remaining signal strength after the data is transmitted a certain distance at a certain signal output intensity can be clarified, and then the data loss amount at this transmission distance can be judged based on the signal strength difference. For example, the obtained relationship: the relationship between signal strength and transmission distance is y = z - ax, where x is the propagation distance, a is the proportional coefficient, z is the initial signal strength, and y is the signal strength at the propagation 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 proportional coefficient.

[0072] S800, obtain the evaluation requirements of the communication device to be evaluated, and evaluate the communication device to be evaluated according to the evaluation requirements and the relationship data, and obtain and output the evaluation result of the communication device to be evaluated. When the relationship among the data loss amount, signal strength, and transmission distance in the communication device to be evaluated is determined, by obtaining the actual evaluation requirements, it can be judged whether the communication device to be evaluated can operate safely under the evaluation requirements. If it can operate safely, the output evaluation result is qualified; if it cannot operate safely, the output evaluation result is unqualified.

[0073] In this 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 made to conform to the actual effect of the communication device to be evaluated in application. By using 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 multiple transmissions, so as to ensure the effectiveness and accuracy of the collected data. When it is determined that the communication device to be evaluated can remain stable under the evaluation requirements, by determining the relationship among the data loss amount, signal strength, and transmission distance, the result obtained when making a satisfaction judgment on the communication device to be evaluated according to the evaluation requirements is more credible, and the evaluation result is improved.

[0074] In step S100, obtain the evaluation space of the communication device and construct an evaluation model based on the evaluation space, including the following steps:

[0075] S110, obtain the evaluation space of the communication device and obtain the distance value between any two positions inside the evaluation space according to the evaluation space;

[0076] S120, screen the distance values between any two positions inside the evaluation space, mark the two positions with the largest distance values as the first placement position and the second placement position respectively, and mark the central position of the first placement position and the second placement position as the center point position;

[0077] S130, set up the communication device to be evaluated at the first placement position, set up the first receiver at the center point position, and set up the second receiver at the second placement position.

[0078] In this embodiment, by obtaining the maximum distance value in the evaluation space, when the communication device to be evaluated performs signal output, the actual transmission distance of the signal is longer, and thus the influence of the environment on the signal is more real and effective, and further the accuracy of the evaluation result when evaluating the communication device to be evaluated is improved. By selecting the first receiver and the second receiver with a double-distance relationship, 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, and thus the analysis process is more concise and the analysis efficiency is improved.

[0079] In step S600, make a comprehensive judgment on the first intermediate information set and the second intermediate information set to determine whether the data output of the communication device to be evaluated is stable, including the following steps:

[0080] S610, based on the time data, compare the first intermediate information and the second intermediate information obtained in the first cycle with the original data;

[0081] S620, if the first intermediate information and the second intermediate information obtained in the first loop are both the same as the original data, then the signal strength of the initial data in the first loop is not analyzed;

[0082] S630, if the first intermediate information in the first loop is the same as the original data, while the second intermediate information is different from the original data, then compare the second intermediate information with the first intermediate information to obtain the first data loss amount; for example, if the first intermediate information obtained in the first loop is a, the original data is z, and the second intermediate information obtained in the first loop is b, then the first data loss amount is b - a.

[0083] S640, obtain the first intermediate information obtained in the second loop, and compare the first intermediate information obtained in the second loop with the first intermediate information obtained in the first loop to obtain the second data loss amount; for example, if the first intermediate information in the second loop is c, then the second data loss amount is c - a.

[0084] S650, compare the first data loss amount with the second data loss amount to obtain the first comparison relationship;

[0085] S660, if the first comparison relationship is that the first data loss amount is less than the second data loss amount, then determine that the data transmission function of the communication device to be evaluated is not stable, and output the corresponding evaluation report; for example, determine the comparison relationship by comparing the numerical values of the first data loss amount b - a and the second data loss amount c - a.

[0086] 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 intermediate information obtained in the third loop, mark the data loss amount between the first intermediate information obtained in the third loop and the first intermediate information obtained in the second loop as the third data loss amount, mark the data loss amount between the first intermediate information obtained in the second loop and the second intermediate information obtained in the second loop as the fourth data loss amount, compare the third data loss amount with the fourth data loss amount to obtain the second comparison relationship; for example, if the second intermediate information in the second loop is d, then the data loss amount between the first intermediate information c and the second intermediate information d in the second loop is d - c, and mark this loss amount as the third data loss amount, if the first intermediate information in the third loop is e, then the data loss amount between the first intermediate information e and the first intermediate information c in the second loop is e - c, that is, the fourth data loss amount, so compare the numerical values of d - c and e - c to determine the comparison relationship.

[0087] For the S680, if the second comparison relationship is the same as the first comparison relationship, it is determined that the communication device to be evaluated is stable in this cycle, and the second cycle is marked until all the built-in cycle quantities are marked.

[0088] In this embodiment, when judging the stability of the communication device to be evaluated in a certain number of cycles, by calculating the data loss amounts among the communication device to be evaluated, the data on the first receiver, and the second receiver in two cycle numbers adjacent to this cycle number, and then comparing the data loss amounts in the two adjacent cycle numbers correspondingly to determine the corresponding comparison relationship, and then comparing the comparison relationships correspondingly 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 this cycle number. Furthermore, it ensures the accuracy of the data of the first transfer information and the second transfer information in the cycle numbers with stability, and further makes the relationship data obtained by judging based on the first transfer information and the second transfer information more accurate, thereby improving the accuracy of the evaluation result.

[0089] 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 among the data loss amount, signal strength, and transmission distance, and it is recorded as relationship data, including the following steps:

[0090] S710, based on the cycle number, calculate the difference between the signal strength of the signal output by the communication device to be evaluated and the signal strength in the first transfer information in the same cycle number to obtain the first signal strength difference, and calculate the difference between the signal strength of the signal output by the communication device to be evaluated and the signal strength in the second transfer information to obtain the 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 b - a, and the second signal strength difference is c - a.

[0091] 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 to obtain the first strength relationship formula; for example, taking the transmission distance as the abscissa and the signal strength as the ordinate, 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, thus obtaining the straight line formula passing through these two points.

[0092] S730, calculate the difference between the signal strength in the first transfer information and the signal strength in the second transfer information in this cycle number to obtain the third signal strength difference;

[0093] S740. Obtain the signal strength of the output signal of the communication device to be evaluated in the next loop and the signal strength of the first relay information at the corresponding loop number, and perform a difference calculation to obtain the fourth signal strength difference.

[0094] S750. Calculate the ratio of the third signal strength difference to the fourth signal strength difference to obtain weighted data. Since at the same output signal strength, the attenuation degree of the signal becomes stronger as the transmission distance increases, the increasing relationship of attenuation is determined through the third signal strength difference and the fourth signal strength difference, and then the linear formula based on the first signal strength difference and the second signal strength difference is corrected. The linear formula is continuously corrected according to the loop number, so that the finally obtained functional relationship can more accurately represent the relationship between the attenuation of the signal strength and the transmission distance.

[0095] S760. Perform weighted processing on the first strength relationship based on the weighted data to obtain the relationship between the signal strength and the transmission distance, and denote it as the first relationship.

[0096] S770. Perform a difference calculation on the signal strength of the first relay information, the signal strength of the second relay information, and the signal strength of the output signal of the communication device to be evaluated in two adjacent loops to obtain the signal strength difference of the first relay information and the signal strength difference of the second relay information in the corresponding loop.

[0097] S780. Perform a difference calculation on the received data of the first relay information, the received data of the second relay information, and the output data of the communication device to be evaluated in two adjacent loops to obtain the data loss amount of the first relay information and the data loss amount of the second relay information in the corresponding loop.

[0098] S790. Based on two adjacent loops, establish a relationship between the signal strength difference of the first relay signal and the data loss amount of the first relay information to obtain the first data relationship, and establish a relationship between the signal strength difference of the second relay information and the data loss amount of the second relay information to obtain the second data relationship.

[0099] S7100. Based on the first data relationship and the second data relationship, determine the compensation amount between the data loss amount and the signal strength difference at the same transmission distance and the same output signal strength.

[0100] S7110. Compensate the first data relationship based on the compensation amount to obtain the relationship between the signal strength difference and the data loss amount, and denote it as the second relationship.

[0101] In this embodiment, when judging the relationship between the signal strength and the propagation distance, by judging the signal attenuation conditions at different transmission distances in the same cycle to determine the relationship between the signal attenuation and the distance, and then judging the attenuation difference of the signals at the same transmission distance in different cycles, so as to continuously correct the determined relationship, and further make the finally obtained correction result conform to the signal attenuation condition during the transmission of the signal actually output by the communication device to be evaluated. Furthermore, the relationship between the signal strength and the transmission distance of the communication device to be evaluated is improved, and thus the evaluation result is more accurate when evaluating the reliability of the communication device to be evaluated according to the evaluation requirements.

[0102] When judging the relationship between the signal strength and the data loss amount, by judging the signal strength difference and the data loss amount between the first relay information, the second relay information and the communication device to be evaluated in each cycle, so as to clarify the relationship between the signal strength difference and the data loss amount in each cycle. Then, based on the relationship between the signal strength difference and the data loss amount in each cycle, determine the data loss amount of each relational expression at the same signal strength. Furthermore, perform a compensation judgment on the data loss amounts of each relational expression to determine the data compensation amount, and compensate the relational expression corresponding to the cycle according to the data compensation amount, so that the data loss amount of the compensated relational expression is the same at any signal strength. Furthermore, the accuracy of judging the relationship between the signal attenuation degree and the data loss amount of the device to be evaluated is improved.

[0103] A method for evaluating the reliability of a communication device further includes evaluating the information delay of the communication device to be evaluated, specifically:

[0104] S1. Obtain 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 the same cycle; in one cycle, the first receiver receives the data output by the communication device to be evaluated, processes the data, and transports the processed data to the communication device to be evaluated as the output data of the device to be evaluated for the next cycle.

[0105] S2. Obtain the data output time of the communication device to be evaluated in the next cycle;

[0106] S3. Calculate 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 the first time data;

[0109] S6. Calculate the difference between the first time data and the sum of the second time data and the third time data to obtain the delay data.

[0110] In this embodiment, by obtaining 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, and calculating the difference between the data output times of the communication device to be evaluated in adjacent cycles to determine the time consumed by the communication device to be evaluated when completing one cycle. Then, by calculating the difference between the data reception time and the data output time of the first receiver in the same cycle, the data processing duration of the first receiver when receiving the signal output by the communication device to be evaluated is obtained. Further, by 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, the time required for the communication device to be evaluated to be transmitted to the second receiver is determined. Among them, the time consumed by the communication device to be evaluated when completing one 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 back 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 be transmitted to the second receiver. The data processing time of the first receiver is known, so by performing difference calculations, the data processing time of the communication device to be evaluated is obtained, and this data processing time is the delay time of the data processing of the communication device to be evaluated.

[0111] 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 by 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 difference calculations, the delay of the communication device to be evaluated during data processing can be quickly and effectively judged, simplifying the judgment process and improving the judgment efficiency.

[0114] S820, based on the output signal strength of the communication device to be evaluated, the signal strength under the evaluation distance requirement, and the second relational expression, determine the data loss amount of the communication device to be evaluated corresponding to the evaluation distance requirement;

[0116] S840, if the judgment criteria are met, determine that the evaluation result is qualified and output;

[0117] S850, if the judgment criteria are not met, determine that the evaluation result is unqualified and output.

[0118] In this embodiment, by using the first relational expression and the second relational expression to judge the requirements in the evaluation requirements, the signal strength and data loss amount under the evaluation distance requirement are simulated, and then the simulated data is compared with the judgment criteria in the evaluation requirements to determine the qualification of the communication device to be evaluated.
