Description
Technical field
This patent is related to communication technique field, and espespecially a kind of echo cancellation testing tool and IP communicating terminal echo cancellation are surveyed
Test system.
Background technology
In instant communication applications, need to carry out both sides or the exchange of multi-party real-time voice, in more demanding field
It closes, is usually all to use external voice box playback, necessarily will produce echo in this way, i.e., after a side speaks, put by the speaker of other side
Then sound is collected by the Mic of other side again and returns to oneself, if but echo is not handled, it will influence speech quality
And user experience, more serious also to form concussion, generation is uttered long and high-pitched sounds.Thereby produce echo cancellation technology, echo cancellation technology
It is one of the typical case of Digital Signal Processing, but echo cancellation technology often first carries out theoretical reasoning, in order to verify it
Actual effect, it is often necessary to be verified by echo cancellation test, all also be made about the test of echo cancellation on the market at present
The method spoken respectively at both ends with two very traditional people, this method need two people to participate in carry out, are unfavorable for doing
Pressure test and prolonged statistics to echo cancellation effect.
Invention content
Based on the above reason, the patent provides a kind of echo cancellation testing tools and IP communicating terminal echo cancellation to test
System, using the testing tool and test system, it can be achieved that automatic test, avoids the consumption of manpower.
Concrete scheme is as follows：A kind of echo cancellation testing tool, it is characterised in that including CODEC chips and MCU chips,
CODEC chips are equipped with earphone cable input module, earphone cable output module；MCU chip is equipped with telecommunications outlet link block, and
MCU chip is connect with CODEC chips, which receives audio signal, earphone by earphone cable input module
Line output module sends audio signal, telecommunications outlet link block receives and sends information data.
Further, a kind of echo cancellation testing tool, it is characterised in that：The earphone cable input module, ear
Machine line output module is 3.5mm earphone cables input module and 3.5mm earphone cable output modules.
Further, a kind of echo cancellation testing tool, it is characterised in that：The telecommunications outlet link block is
RJ45 link blocks.
System is tested using a kind of IP communicating terminals echo cancellation made by a kind of echo cancellation testing tool of the above
System, it is characterised in that including PC computer ends, echo cancellation testing tool, Ethernet switch, IP communicating terminals to be measured, wherein
PC computer ends connect using earphone cable with echo cancellation testing tool and carry out the mutual transmission of audio data, echo cancellation test
Tool connect the mutual transmission for row information data of going forward side by side with Ethernet switch with telecommunications outlet connector, Ethernet switch with
IP communicating terminals to be measured connect the mutual transmission for row information data of going forward side by side with telecommunications outlet connector.
Further, the earphone cable is 3.5mm earphone cables
Further, the telecommunications outlet connector is RJ45 lines
After employing a design in which, our this patent can accomplish not needing personnel's participation during the test,
Whole-course automation is tested, and related personnel is notified with lettergram mode once there is echo to be captured, so very big that save test manpower money
Source puts into and improves the accuracy of test.
Description of the drawings
Fig. 1 is the structural schematic diagram of the echo cancellation testing tool
Fig. 2 is the structural schematic diagram that system is tested in the IP communicating terminal echo cancellation
Specific implementation mode
As shown in Figure 1, a kind of echo cancellation testing tool 1, it is characterised in that including CODEC chips 12 and MCU chip
13, CODEC chips 12 are equipped with 3.5mm earphone cables input module 121,3.5mm earphone cables output module 122；In MCU chip 13
Equipped with RJ45 link blocks 131, and MCU chip 12 is connect with CODEC chips 13, which passes through 3.5mm
Earphone cable input module 121 receives audio signal, 3.5mm earphone cables output module 122 sends audio signal, RJ45 link blocks
131 receive transmission information data.
As shown in Fig. 2, system 2 is tested in a kind of IP communicating terminals echo cancellation, it is characterised in that including PC computer ends 21, return
Sound eliminates testing tool 1, Ethernet switch 22, IP communicating terminals 23 to be measured, and wherein PC computer ends 21 are tested with echo cancellation
Tool 1 using 3.5mm earphone cables 211 connect and carry out PCM audio data transmission interact, echo cancellation testing tool 1 with
Too network switch 22 connects the transmission interaction for row information data of going forward side by side with RJ45 lines 221, and Ethernet switch 22 and IP to be measured is logical
The transmission that news terminal 23 connects row information data of going forward side by side with RJ45 lines 231 interacts.
When original audio signal is received the CODEC that line is sent to echo cancellation testing tool by PC computer ends by earphone
Original audio signal is carried out data encoding by chip, CODEC chips, obtains original audio digital signal, later CODEC by this
Original audio digital signal after coding sends MCU chip to；MCU chip leads to the original audio digital signal that step 1 obtains
It crosses RJ45 lines and is sent to Ethernet switch, Ethernet switch is further transmitted to IP communicating terminals to be measured；IP to be measured
Communicating terminal receives handled after original audio digital signal after send out audio digital signals to be measured and then pass through Ethernet
Interchanger is sent to the MCU chip built in echo cancellation testing tool, and MCU chip is transferred to CODEC chips and is decoded,
PCM audio signals to be measured are generated, and do noise reduction process；MCU chip is further sent out audio signal to be measured is obtained after decoding process
PC computer ends are given, PC computer ends respectively compare and analyze original audio signal and audio signal to be measured, and by the analysis
In the exception that captures related personnel is notified in a manner of mail.
