All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Detailed description of the preferred embodiment
The embodiment of the invention firstly describes a quantitative test analysis method of carrier communication performance. Fig. 1 shows a flow chart of an embodiment of a method for quantitative test analysis of carrier communication performance according to the present invention. As shown in fig. 1, the method comprises the steps of:
and S1, receiving and analyzing the quantitative test analysis command sent by the test terminal.
Since there are usually a plurality of main nodes and a plurality of sub-nodes in a communication network, when performing quantitative test analysis of carrier communication performance, it is first necessary to select sub-nodes to be tested that communicate with each main node, and to allocate test channels for communication one by one for the communication situation of each main node (for example, if one main node communicates with six sub-nodes, six test channels are allocated, and signal transmission is performed between the main node and each sub-node through each allocated test channel). On the basis, a user can send a quantitative test analysis instruction to the main node through the test end to start a test process, wherein the quantitative test analysis instruction comprises sub-nodes to be tested and test channels corresponding to the sub-nodes one to one.
S2, sending a first carrier signal to be tested to the sub-node through the test channel, and acquiring a first test data group of the first carrier signal and a second test data group of a second carrier signal received by the sub-node.
In order to test the carrier communication performance, after a quantitative test analysis process is started, a main node sends a first carrier signal to a corresponding sub-node to be tested and records a first test data set; after the first carrier signal is sent, the sub-node to be tested receives the attenuated second carrier signal and sends a second test data group of the second carrier signal to the main node. Through the process, the main node comprises the first test data group of the unattenuated first carrier signal and the second test data group of the attenuated second carrier signal, and on the basis, the attenuation condition of the carrier communication can be obtained only by comparing and analyzing the first test data group and the second test data group, so that the communication performance of the carrier communication is analyzed on the basis.
In order to perform comparison analysis on the attenuated signal and the unattenuated signal in the subsequent process, power, frequency, current, voltage, phase difference, amplitude modulation and the like are selected as the basis of analysis and comparison (parameters included in a test data set), so that the attenuation degree in the carrier communication process is quantized, and the carrier communication performance is further analyzed. That is, in one embodiment, the first test data set and the second test data set each include power, frequency, current, voltage, phase difference, and amplitude modulation.
And S3, calculating a performance index group of the second carrier signal relative to the first carrier signal according to the first test data group and the second test data group, thereby completing quantitative test analysis and sending an analysis result to the test end.
After the first test data group and the second test data group are obtained, the attenuation degree of the second carrier signal relative to the first carrier signal can be calculated and quantized, and therefore the communication performance of carrier communication is represented through the performance index group obtained through calculation. In one embodiment, the set of performance indicators includes an integrity index, a continuity index, a distortion index, a delay index, and the like. Through the integrity index, the continuity index, the distortion index and the delay index, the attenuation condition of the signal in the carrier communication process can be evaluated from multiple aspects, so that quantitative test analysis is completed, and after an analysis result is obtained, the analysis result can be sent to the test end, so that the test end sends the analysis result to a user.
In one embodiment, the manner of sending to the user includes: textual information, voice information, video information, image information, or a combination of one or more of the foregoing.

In one embodiment, before receiving and analyzing the quantitative test analysis command sent by the test end, the test end performs the following steps: receiving and analyzing a test instruction input by a user, thereby obtaining a test node to be tested; the test nodes comprise main nodes and sub nodes; distributing a corresponding number of test channels with different frequency channels according to the number proportion of the main node and the sub-nodes, so that the main node respectively performs test communication with the corresponding sub-nodes through each test channel; and generating a quantitative test analysis instruction according to the child nodes and the test channels corresponding to the child nodes one to one, and sending the quantitative test analysis instruction to the main node.
The embodiment of the invention describes a quantitative test analysis method of carrier communication performance, which simplifies the analysis process and improves the convenience of the quantitative test analysis of the carrier communication performance by calculating the performance index group of a second test data group of a second carrier signal after attenuation relative to a first test data group of a first carrier signal without attenuation.

In order to test the carrier communication performance, after a quantitative test analysis process is started, a main node sends a first carrier signal to a corresponding sub-node to be tested and records a first test data set; after the first carrier signal is sent, the sub-node to be tested receives the attenuated second carrier signal and sends a second test data group of the second carrier signal to the main node. Through the process, the main node comprises the first test data group of the unattenuated first carrier signal and the second test data group of the attenuated second carrier signal, and on the basis, the attenuation condition of the carrier communication can be obtained only by comparing and analyzing the first test data group and the second test data group, so that the communication performance of the carrier communication is analyzed on the basis.
In order to perform comparison analysis on the attenuated signal and the unattenuated signal in the subsequent process, power, frequency, current, voltage, phase difference, amplitude modulation and the like are selected as the basis of analysis and comparison (parameters included in a test data set), so that the attenuation degree in the carrier communication process is quantized, and the carrier communication performance is further analyzed.

In one embodiment, the set of performance indicators includes an integrity index, a continuity index, a distortion index, a delay index, and the like. Through the integrity index, the continuity index, the distortion index and the delay index, the attenuation condition of the signal in the carrier communication process can be evaluated from multiple aspects, so that quantitative test analysis is completed, and after an analysis result is obtained, the analysis result can be sent to the test end, so that the test end sends the analysis result to a user.
In one embodiment, the manner of sending to the user includes: textual information, voice information, video information, image information, or a combination of one or more of the foregoing.
In one embodiment, in order to ensure that the quantitative test analysis method is accurate enough, the fluctuation condition of each index in the performance index set needs to be monitored, and when the index fluctuation reaches a certain threshold, the method is considered to be not accurate enough and needs to be adjusted and corrected.
