Embodiment
Below in conjunction with the drawings and specific embodiments, technology contents of the present invention is further described.
Under normal circumstances, when user uses dispatch terminal, can pick up the below that dispatch terminal is positioned over user's face, namely substantially keep level with the oral area of user, now the voice messaging of user can be transferred in the dispatch terminal of the other user more clearly.When user is used to complete, somewhere can be hung on conveniently, facilitate take next time.But partner is due to can not simultaneously on-hook, or when multiple user uses dispatch terminal, only have certain customers' on-hook, other users keep using, and now the on-hook sound of on-hook user can form more ear-piercing noise in the user just using terminal simultaneously.The lighter affects the service quality of user, and severe one user can not use.
In order to solve the problem, the invention provides a kind of denoising method based on acceleration transducer, comprising the following steps:
Receive the acceleration information of handle, this acceleration information carrys out acceleration sensor;
Process acceleration information, for determining direction and the size of this acceleration;
If this side up, accekeration exceedes set point, then delete the speech data of buffer memory, stops sending speech data;
If the accekeration that this side up does not exceed set point, then gather voice data concurrency and send, recover normal talking.
First, introduce the acceleration information receiving handle, this acceleration information carrys out the step of acceleration sensor.
After user's communication completes, place terminal, now can there is acceleration in terminal, and for better measuring this acceleration, the present invention is provided with acceleration transducer in the handle of dispatch terminal, and keep fixing.This acceleration transducer can retrieve the acceleration in X, Y, Z tri-directions.After user places handle, collision desktop or hook form impact noise.Voice collecting circuit and buffer circuit being set in the host-processor of dispatch terminal, now, carrying out buffer memory to gathering speech data from handle microphone.This impact noise is carried out buffer memory in the form of speech, is ready for sending to other users.Acceleration transducer gathers the acceleration of this handle, is transferred to the host-processor of dispatch terminal.
Secondly, introduce process acceleration information, for the step in the direction and size of determining this acceleration.
After the host-processor of dispatch terminal receives the data of acceleration transducer, these data are processed, obtains the direction of acceleration, size, and extract the set point of acceleration in this side up face, both are compared, obtains comparative result.
Again, if introduce, this side up, accekeration exceedes set point, then delete the speech data of buffer memory, stops the step sending speech data.
After host-processor obtains comparative result, if now the acceleration of handle has exceeded set point (comprising the situation that both are equal) in the direction in which, then the speech data of buffer memory has been deleted by host-processor, and stops sending speech data to the other side.That is, impact noise during user's on-hook is not sent to the other side.Can ensure like this, also normally use the user carrying out conversing, can not Consumer's Experience be reduced.
Finally, if introduce the accekeration that this side up not exceed set point, then gather voice data concurrency and send, recover the step of normal talking.
If comparative result is less than the party's set point upwards, the non-on-hook of user is described, belongs to the dispatch terminal that the excessive or other reasons of action causes and rock.Start timer to start working; When after the time value that timer reaches set, send enabling signal to voice collecting circuit and buffer circuit.The now time delay regular hour, period does not send speech data, filters out by this impact noise, prevents from affecting other users.After this time, recover normal talking, host-processor restarts buffer circuit, and voice collecting circuit gathers the speech data in handle microphone, is sent to the other side.By delay process, the present invention can filter out less impact noise, thus reduces the impact on user's communication.
For embodying the superiority of the denoising method based on acceleration transducer provided by the invention further, present invention also offers a kind of host-processor, as shown in Figure 2, comprising:
Receive acceleration information unit, for receiving the acceleration information of acceleration sensor;
Process acceleration information unit, for resolving direction and the size of acceleration information;
Acceleration information comparing unit, for more above-mentioned acceleration and set point, and exports comparative result;
Control unit, according to comparative result to voice collecting circuit and buffer circuit sending controling instruction.
For embodying the superiority of the denoising method based on acceleration transducer provided by the invention further, present invention also offers a kind of dispatch terminal, as shown in Figure 3, comprise: acceleration transducer, voice collecting circuit, buffer circuit, handle, microphone and host-processor, wherein, acceleration transducer is arranged on the inside of handle, and is fixed on this handle, and its output is connected to host-processor.Microphone, voice collecting circuit, buffer circuit is arranged on the inside of handle, wherein
Microphone converts user voice or impact noise to electric signal transmission to voice collecting circuit, and after the process of voice collecting circuit, be transferred to buffer circuit again, store certain hour by buffer circuit, cache-time can be arranged.
Host-processor receives the current accekeration of handle that acceleration sensor gathers, and processes, obtain direction and the size of this brief acceleration to this accekeration, namely handle direction with impact size.The set point of taking out the party's acceleration upwards compares.If the acceleration of handle is greater than set point, then host-processor controls buffer circuit, deletes the speech data of institute's buffer memory, and stops sending speech data to the other side.
If the acceleration of handle is less than set point, then, after the time delay regular hour, restart buffer circuit, buffer memory is carried out to the speech data that voice collecting circuit gathers, and is sent to the other user.
The present invention is by arranging acceleration transducer, and the acceleration of collection scheduling terminal handle, is processed by the impact noise of this acceleration to handle, finally eliminates the interference of impact noise to meeting, other user speech, improves the Consumer's Experience in meeting.
Above the denoising method based on acceleration transducer provided by the present invention, host-processor and dispatch terminal are described in detail.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from connotation of the present invention, all by formation to infringement of patent right of the present invention, corresponding legal liabilities will be born.
