Detailed Description
The technical scheme in the application is further described in detail below with reference to the accompanying drawings.
It should be appreciated that human-based active intervention may be employed, such as by actively controlling (e.g., using a controller, etc.) the heat dissipation of the main chassis before a meeting or training is initiated, to reduce noise, but whether the controller is available before each use and whether the user is using it is a potential problem, and if the controller is managed, additional management costs may be added.
According to the active terminal control method disclosed by the embodiment of the application, the surrounding environment of the main control cabinet is analyzed and judged in a voice recognition mode, when the surrounding environment of the main control cabinet changes, the changes can be screened, and when specific changes are screened, corresponding control instructions are issued to the terminal.
Referring to fig. 1, an active terminal control method disclosed in an embodiment of the present application includes the following steps:
s101, responding to received sound information, starting to calculate the receiving time of the sound information, and recording the receiving time as first time length information;
s102, comparing the first time length information with time length threshold information;
s103, when the first time length information is larger than the time length threshold information, converting the received sound information to a frequency domain to obtain frequency domain image information of the sound information, wherein the frequency domain image information comprises one or more pieces of numerical information; and
s104, comparing the numerical value information with the set numerical value range information;
when the first set number of numerical value information falls in the set numerical value range information, first control instruction information is issued to the terminal.
Specifically, in step S101, after receiving the sound information, calculation of the time of receiving the sound information is started, and the time is recorded as the first time length information, that is, the method in the embodiment of the present application is started based on the occurrence of the sound, and no physical device such as a controller is required.
The length accumulation of the recorded sound information in the time dimension is aimed at reducing the occurrence of erroneous judgment, and if the terminal is controlled by the occurrence of sound, the sound of opening and closing the door, a short-time utterance and temporary short-term communication are all possibly regarded as start signals, which obviously cause a large number of erroneous judgment.
It should also be understood that for a conference or training, the speech is mainly speaking, that is, the voice information can exist for a long time, and the door opening and closing voice, short-time speaking, temporary short-time communication, etc. exist for a short time, and for convenience of description, these are collectively called noise information, and the noise information can be excluded by judging the existence time of the voice information.
The noise information is removed by step S102, and in step S102, the first time length information is compared with the time length threshold information, where the following cases may occur:
the first time length information is smaller than the time length threshold information, and the received sound information can be judged to belong to noise information;
the first time length information is greater than the time length threshold information, and the received sound information is converted into the frequency domain for analysis, that is, the content in step S103.
The first time length information is equal to the time length threshold information, and whether the received sound information belongs to noise information or is converted to a frequency domain for analysis needs to be selected according to specific settings, and both processing modes are allowed.
In step S103, referring to fig. 2, the received sound information is converted into frequency domain to obtain frequency domain image information of the sound information, where the frequency domain image information includes one or more numerical information, and the purpose of the step is to start to analyze the sound information to determine whether the sound information belongs to a conference or training.
Step S103 is performed when the first time length information is greater than the time length threshold information, that is, step S103 is performed with a trigger condition, and is performed only when the trigger condition is satisfied.
It should be understood that the time length of the simple statistical sound information is obviously simpler than that of the sound information analysis, and the statistical sound information consumes less computing resources from the viewpoint of implementation cost, and noise information in the statistical sound information can be shielded, so that the analysis amount of the sound information is effectively reduced.
From another point of view, if each piece of sound information is analyzed, a large amount of computing resources are inevitably consumed because the sound information is widely available, but in a specific use environment, the number of conferences is relatively small, for example, one or two to three places a day, and it is obvious that it is not appropriate to analyze each piece of sound information.
For the analysis of converting the sound into the frequency domain, it can be understood that the sound is composed of a plurality of sound waves, each of which has a different frequency and amplitude, and which are doped together in the time domain, but which can be decomposed into a plurality of waveforms by fourier transformation in the frequency domain, the difference between the peak value and the trough value of each waveform can be regarded as a characteristic value of this waveform, that is, the numerical information mentioned in step S103.
In step S104, the numerical information obtained in step S103 is compared with the set numerical range information, and when the first set number of numerical information falls within the set numerical range information, the first control instruction information is issued to the terminal.
It should be appreciated that the analysis and calculation are error-prone, i.e. the resulting value can only be moved towards the true value without limitation, so that the accuracy of the determination of the value information using an increased number of determinations is higher.
It should also be appreciated that the sound characteristics of different persons are different, and the frequency domain ranges fed back to the frequency domain are not nearly identical, but by analyzing a large number of sounds, a characteristic range, that is, the set value range information mentioned in step S104, can be obtained.
In some possible implementations, the number of numerical information may be five, ten, twenty, or even more, which may be continuous or discrete.
When the number of the numerical value information falling in the set numerical value range information is larger than or equal to the first set number, the first control instruction information is issued to the terminal, the power of equipment generating noise on the main control chassis is reduced, and the purpose of reducing the noise is achieved.
In the whole, the method is divided into two steps of screening and judging for the change of the sound in the surrounding environment, wherein the screening process is judged by the accumulated length of the sound in time, the purpose of filtering the sound which appears in a short time is achieved, and the filtering mode is not specific.
In the judging process, the comparison is performed by analyzing the sounds, so as to judge whether the sounds meeting the time length requirements meet the preset sound model (namely, the numerical range information mentioned in the step S104), if the sounds meet the sound model, the first control instruction information is issued to the associated terminal, and the judging process is used for screening out the sound information meeting the time length requirements but not meeting the sound model.
According to the terminal control method provided by the embodiment of the application, the sound information in the environment is analyzed by using two modes of time length screening and sound model analysis, most of sound information belonging to noise can be filtered out by the time length screening, the sound information which is not filtered out can be analyzed by the sound model analysis, and the mode consumes less calculation resources and is more accurate in judgment.
It should be understood that, for the sound information in the environment, there may be a case where there is a break, that is, the sound is intermittent in time sequence, referring to fig. 3 (a) and 3 (B), as a specific embodiment of the active terminal control method provided in the application, the following steps are added;
s201, acquiring a plurality of pieces of first time length information on a unit time length;
s202, accumulating and calculating a plurality of pieces of first time length information in unit time length to obtain second time length information; and
s203, comparing the second time length information with the time length threshold information.
Specifically, in step S201, a plurality of pieces of first time length information of a unit time length is obtained, where the unit time length is a preset value, for example, two seconds, three seconds, or five seconds, and the first time length information is isolated, that is, discontinuous, from the time sequence, a period of time in the time sequence is intercepted, and then the pieces of first time length information of the period of time are accumulated, so as to obtain second time length information, that is, the content in step S202.
It will be further understood that in some cases, the sound change in the surrounding environment may not meet the requirement of time length screening, but may meet the requirement of analysis of the sound model, if only time length screening is performed, a situation of erroneous judgment may occur, in addition, during the process of sound information collection, a situation that sound is continuous but is intermittently collected may occur, and after the content in steps S201 to S203 is added, the above situations may be largely included in the range of analysis, so as to reduce the probability of erroneous judgment.
It should be further understood that the contents of steps S201 to S203 are performed when the first time length information is smaller than the time length threshold information, that is, for the first time length information, there are two analysis modes, which are performed simultaneously, to satisfy the time length requirement, and the first is that the time length of one sound information satisfies the requirement, and the second is that the time length of a plurality of sound information is sufficient, and both the two conditions trigger the sound model analysis.
Of course, there are some situations, for example, it is said that "we prepare for meeting", "quiet at home", or "turn the mobile phone to mute" and the like, which are only used in special scenes, and if these sentences occur, it is possible to directly make a decision and issue the first control instruction information to the terminal.
Therefore, when the first time length information is greater than the time length threshold information, keyword information in the voice information is identified, and the number of the keyword information is one or more, that is, two processing modes are adopted for the voice information meeting the time length screening requirement, wherein the first mode is voice model analysis, and the second mode is keyword information identification.
It should be understood that the analysis of the acoustic model and the recognition of the keyword information are both time-consuming, and there must be a problem of speed in the simultaneous process, so that in the simultaneous process, it is sufficient in which way the result is obtained first.
It should also be appreciated that the manner in which a fixed acoustic model is placed for comparison is significantly faster, and the speed and accuracy of determination is significantly higher, than in the case of analyzing a complete message, and that keyword message identification is more like a trigger mechanism, as a complement to acoustic model analysis.
Referring to fig. 4, as a specific embodiment of the active terminal control method provided by the application, the following steps are added, where the steps are performed after the first control instruction information is issued to the terminal:
s301, receiving sound information according to a set frequency;
s302, converting the received sound information to a frequency domain to obtain frequency domain image information of the sound information, wherein the frequency domain image information comprises one or more pieces of numerical information; and
s303, comparing the numerical value information with the set numerical value range information;
and when all the numerical value information is out of the set numerical value range information, issuing second control instruction information to the terminal.
The content of steps S301 to S303 is further optimized for control, specifically, in step S301, sound information is received according to a set frequency, and the purpose of receiving the sound information is to continuously monitor sound changes in the surrounding environment, so that after the conference or training is finished, second control instruction information can be issued to the terminal, so that the operation of the terminal is restored to a normal level.
It will be appreciated that the sound information is received at the set frequency at step S301, i.e. the collection of sound information is intermittent rather than continuous at this step. Compared with the mode of interval acquisition and continuous acquisition, the method has the advantages that obviously consumed operation resources are fewer in a continuous process, and the method is more in line with actual scene requirements.
The contents of step S302 and step S303 are the same as those of step S103 and step S104, and the purpose is to determine the sound information received in step S301, and when some numerical information falls within the set numerical range information, it is indicated that a meeting or training is still in progress, and at this time, step S301 is continuously executed, and when all the numerical information falls outside the set numerical range information, it is indicated that the meeting or training is completed, and at this time, second control instruction information is issued to the terminal, so that the operation of the terminal is restored to the normal level.
Referring to fig. 5, further, the method of sending the second control instruction information to the terminal is optimized, and specifically, when all the numerical information falls outside the set numerical range information, after a waiting time, the second control instruction information is sent to the terminal.
It should be understood that when all the numerical information falls outside the set numerical range information, there may be a situation that a conference or training is finished but personnel have not gone out of the field or a longer silent period occurs, and if the second control instruction information is directly issued to the terminal, the operation of the terminal is restored to a normal level, then negative effects will be generated, resulting in a worse user experience, after the waiting time is increased, sufficient leave time can be left for personnel, and meanwhile, erroneous judgment generated after the conference or training goes into the silent period can be avoided as much as possible.
Referring to fig. 6, as a specific embodiment of the active terminal control method provided in the application, after entering the waiting time, the following steps are further added:
s401, receiving sound information according to a set frequency;
s402, converting the received sound information to a frequency domain to obtain frequency domain image information of the sound information, wherein the frequency domain image information comprises one or more pieces of numerical information;
s403, comparing the numerical value information with the set numerical value range information; and
s404, when the existing numerical value information falls within the set numerical value range information, the waiting time is recalculated.
Specifically, in step S401, the audio information is received at a set frequency, and the content of this step is the same as that in S301, and the content of step S402 and step S403 is the same as that of step S103 and step S104, so that the audio information received in step S401 is determined, and specific determination is performed in step S404, and may be divided into two cases:
first, no numerical information falls within the set numerical range information, and at this time, the contents in step S401 and step S403 are continuously executed, and after the waiting time is reached between the executions, the second control instruction information is issued to the terminal, so that the operation of the terminal is restored to the normal level.
Second, there is numerical information falling within the set numerical range information, at which time the contents of step S401 and step S403 are continued to be executed, but the execution time is not accumulated any more, but cleared.
Thus, the situation that noise suddenly increases when a person leaves the field or enters a silencing period can be effectively avoided.

the first acquisition unit is used for responding to the received sound information, starting to calculate the receiving time of the sound information and recording the receiving time as first time length information;
