According to the system, the time error of the terminal can be effectively eliminated, and the actual state of the network is reflected; the method comprises the following steps: S1, initializing system parameters; s2, performing Beidou satellite time synchronization; s3, detecting a system function; s4, obtaining Beidou time when the sending module starts to send data and data sending completion time, and the beidou time that the receiving module receives the data sent by the sending module and the time from data receiving to data confirmation of the receiving module; s5, calculating the data transmission delay; s6, evaluating the communication quality; themethod is high in network delay calculation precision and good in stability.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a communication quality perception system. Background technique [0002] In the power system, it is necessary to know the service quality of the network system in a timely manner, and often evaluate the service quality to provide reference data for network optimization, fine-tuning the network operation structure, or adding necessary network equipment; the service quality can be tested from the aspects of data rate and communication delay , because different services have different requirements for system communication delay and communication rate, you can measure the access communication quality of different services to understand the operation of the entire network, and avoid communication data overtime in important services, resulting in unnecessary losses. [0003] There are currently three main methods for testing data rate and network delay. One way i...

Problems solved by technology

[0004] At present, most of the methods for testing data rate and network delay are two-way delay method. The data is sent from the test end to the target test server, and the server returns instructions to the test end. The test end uses the two time differences to analyze the network delay. However, in the power system Among them, the amount of uplink data is very large, while the amount of downlink data is small. Using the two-way delay method to test the network response speed is difficult to truly reflect the actual status of the network, which is slightly insufficient as a standard basis for network optimization.
