Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The embodiment of the application provides an arrival reminding method, an arrival reminding device, a storage medium and electronic equipment. The main body of the arrival reminding method can be the arrival reminding device provided in the embodiment of the present application, or an electronic device integrating the arrival reminding device, wherein the arrival reminding device can be implemented in hardware or software, and the electronic device can be a computing device such as a laptop computer, a computer monitor including an embedded computer, a tablet computer, a cellular phone, a media player, or other handheld or portable electronic devices, smaller devices (such as a wristwatch device, a hanging device, an earphone or headphone device, a device embedded in glasses or other devices worn on the head of a user, or other wearable or miniature devices), a game device, a navigation device, an embedded system, or the like.
Referring to fig. 1, fig. 1 is a schematic flow chart of a station arrival reminding method according to an embodiment of the present application. The arrival reminding method is applied to the electronic device provided by the application, the electronic device comprises a processor, a special voice recognition chip and a microphone, and as shown in fig. 1, the flow of the arrival reminding method provided by the embodiment of the application can be as follows:
in 101, a processor receives a request for reminding of arrival, and determines a target public transportation station needing to be reminded of arrival according to the request for reminding of arrival.
It should be noted that the types of public transportation referred to in the following embodiments include, but are not limited to, subways, buses, and the like.
In the embodiment of the present application, the processor is a processor suitable for general purpose processing tasks, such as a processor of an ARM architecture. The dedicated voice recognition chip is a dedicated chip designed for voice recognition, such as a digital signal processing chip designed for voice recognition, an application specific integrated circuit chip designed for voice recognition, and the like, which has lower power consumption than a general-purpose processor and is suitable for processing a voice recognition task. Wherein, any two of the special voice recognition chip, the processor and the microphone are connected through a communication bus (such as an I2C bus) to realize data interaction. Specifically, the model of the processor and the model of the dedicated voice recognition chip can be selected by those skilled in the art according to actual needs. For example, processor models that may be selected include, but are not limited to, CellCephalon 855+, CellCephalon 845, CellCephalon 820, CellCephalon 810, CellCephalon 710, and the like.
The microphone included in the electronic device may be an internal microphone or an external microphone (which may be a wired microphone or a wireless microphone).
When the electronic equipment is in a bright screen state, the processor receives an arrival reminding request input by a user. For example, the processor receives the arrival reminding request input by the user through an arrival reminding interface provided by the public transportation application running in the foreground.
For example, referring to fig. 2, the arrival reminding interface shown in fig. 2 includes all public transportation stations through which a public transportation route passes, that is, illustrated public transportation station 1 to public transportation station 9, and the processor may receive an arrival reminding request corresponding to a public transportation station according to an "alarm clock" control associated with any public transportation station by a user, where the arrival reminding request carries a station identifier (for example, a station name of the station) of the corresponding public transportation station.
After receiving the input arrival reminding request, the processor analyzes the station identifier carried by the arrival reminding request, and sets the public transport station corresponding to the station identifier as a target public transport station needing arrival reminding.
At 102, a target stop number of public transportation stops that the electronic device needs to pass through to reach the target public transportation stop is obtained by the processor.
After determining the target public transportation station needing to be reminded of the arrival station, the processor further acquires the number of the target stations of the public transportation stations which are required to be passed by the electronic equipment to reach the target public transportation station.
The processor firstly acquires a base station identifier of a current base station which establishes mobile communication connection with the electronic equipment at present, and determines a public transport station corresponding to the current base station according to a preset corresponding relation between the base station identifier and the public transport station, and records the public transport station as the current public transport station.
It should be noted that the base station provides network access service for the electronic device, and the location of the electronic device is usually fixed, and when the electronic device establishes a mobile communication connection with a certain base station, the location of the electronic device can be determined. Based on this, in the embodiment of the application, the base station is associated with the public transportation station closest to the base station in advance, and the corresponding relationship between the base station identifier and the public transportation station is further established. The base station identifier is used to uniquely characterize the base station, and a person of ordinary skill in the art can select a parameter as the base station identifier according to actual needs, for example, in the embodiment of the present application, a cell identifier and a location area code are used as the base station identifier.
After the current public transport station is determined, the processor acquires pre-stored route information from the current public transport station to the target public transport station, and determines the number of target stations of the public transport stations which are required to pass by the electronic equipment to reach the target public transport station from the current public transport station according to the route information, the current public transport station and the target public transport station.
For example, for the public transportation route from the public transportation station 1 to the public transportation station 9 shown in fig. 2, assuming that the target public transportation station is the public transportation station 9, if the determined current public transportation station is the public transportation station 3, the processor may determine that the number of target stations of the public transportation stations that the electronic device needs to pass through to reach the target public transportation station is 6.
In 103, the microphone is controlled by a dedicated speech recognition chip to pick up an external audio signal.
After determining the number of target stations of the public transportation stations which are required to pass by when the electronic equipment reaches the target public transportation stations, the processor instructs the special voice recognition chip to start the station passing detection, namely, whether the electronic equipment passes the public transportation stations or not.
Correspondingly, the special voice recognition chip controls the microphone to collect external audio signals according to the instruction of the processor for station-crossing detection.
At 104, the audio signal is recognized through a special voice recognition chip and a processor, and the number of stations of the electronic equipment which pass through the public transportation station is obtained.
The special voice recognition chip and the processor carry out station passing detection according to the collected audio signals, namely whether the collected audio signals are the audio signals passing through public transport stations is recognized, if yes, the electronic equipment is determined to pass through one public transport station, and therefore the number of stations of the electronic equipment passing through the public transport stations can be obtained.
For example, the dedicated voice recognition chip first recognizes whether the audio signal is an audio signal passing through a public transportation station, and when it is recognized that the audio signal is an audio signal passing through a public transportation station, the audio signal is provided to the processor, and the processor recognizes again whether the audio signal is an audio signal passing through a public transportation station, and if so, it is determined that the electronic device passes through a public transportation station.
For example, the dedicated voice recognition chip may determine whether the audio signal includes an audio feature of a public transportation station, and if so, the audio signal is an audio signal passing through the public transportation station; the processor can directly compare the audio signal provided by the microphone with the audio signal which is collected in advance and passes through the public transport station, and when the comparison between the audio signal provided by the microphone and the audio signal passes through the public transport station, the audio signal is judged to be the audio signal passing through the public transport station.
In 105, when the number of the current station is consistent with the number of the target station, a preset arrival reminding operation is executed by the processor.
The processor judges whether the number of the stations of the electronic equipment which have passed through the public transport stations is consistent with the number of the target stations in real time, when the number of the stations of the electronic equipment which have passed through the public transport stations is consistent with the number of the target stations, the electronic equipment is shown to reach the target public transport stations which need to be reminded of arrival at the moment, and at the moment, the processor executes preset arrival reminding operation. Regarding the type of the arrival reminding operation, the embodiment of the present application is not particularly limited, and a person skilled in the art can set the operation according to actual needs, including but not limited to audio, video, image, text and other arrival reminding modes. For example, the processor may play a preset arrival reminding alarm sound, and remind the user that the arrival is currently reached by using the arrival reminding alarm sound.
According to the method, the processor receives the arrival reminding request, the target public transport stations needing arrival reminding are determined according to the arrival reminding request, the number of the target stations of the public transport stations which the electronic equipment needs to pass through and are required to reach the target public transport stations is obtained, the special voice recognition chip controls the microphone to collect external audio signals, the special voice recognition chip and the processor are used for recognizing the collected audio signals, the number of the stations which the electronic equipment has passed through the public transport stations is obtained, and finally when the number of the stations which have passed through is consistent with the number of the target stations, the processor executes preset arrival reminding operation. Compared with the related art, the station arrival reminding can be realized without satellite positioning, so that the power consumption of the electronic equipment for realizing the station arrival reminding can be effectively reduced.
In one embodiment, recognizing the audio signal through a dedicated voice recognition chip and a processor to obtain the number of stations that the electronic device has passed through the public transportation station includes:
(1) identifying whether the audio signal comprises frequency components corresponding to public transport stations or not through a special voice identification chip;
(2) when the audio signal is identified to comprise the frequency component, identifying whether the audio signal is a preset audio signal corresponding to a public transport station or not through a processor;
(3) and obtaining the station number according to the identification times of the processor identification result.
It should be noted that for different types of public transportation stations, there are specific sound characteristics.
For example, for a bus stop, when a bus passes through the bus stop, there is a sound characteristic of a warning sound of the opening/closing of the bus (i.e., opening the door when arriving at the bus, closing the door when leaving the bus); for the subway station, when the subway passes through the subway station, the sound characteristic of the warning sound of opening/closing the subway (the door is opened when the subway arrives at the station and closed when the subway leaves the station) exists.
For example, referring to fig. 3, taking a subway station as an example, fig. 3 is a spectrogram of a cue tone when a subway opens and closes a door, and it can be seen from the spectrogram that the cue tone of the subway opens and closes the door consists of a plurality of frequency components. Correspondingly, the corresponding relation between the subway station and the corresponding frequency component can be established in advance. And in the same way, the corresponding relation between the public transport station and the corresponding frequency component can be established.
Therefore, when the audio signal is identified, whether the frequency component corresponding to the public transport station is included in the audio signal or not can be identified by the special voice identification chip. If yes, the electronic equipment can be preliminarily judged to pass through a public transport station, the audio signal is provided to the processor, and the processor carries out further identification. The processor identifies whether the audio signal is a preset audio signal corresponding to a public transportation station, and if so, the electronic equipment can be determined to have passed one public transportation station.
Therefore, the processor can obtain the number of the stations of the electronic equipment which have passed through the public transportation station according to the identification times of which the identification result is yes, wherein the processor can directly use the identification times of which the identification result is yes as the number of the stations of the electronic equipment which have passed through the public transportation station.
For example, the processor respectively identifies a plurality of audio signals provided by the dedicated voice recognition chip at different times, and if the number of times that the identification result is yes is N, the number of stations that indicate that the electronic device has passed through public transportation stations is also N.
In one embodiment, before identifying whether the audio signal includes the frequency component corresponding to the public transportation station by the dedicated voice recognition chip, the method further includes:
and filtering out human voice frequency components in the audio signal through a special voice recognition chip.
Before the audio signal is identified, the human voice frequency components in the audio signal can be extracted and filtered out, so that the interference of the human voice frequency components on the identification is reduced.
In one embodiment, identifying whether the audio signal includes a frequency component corresponding to a public transportation station by a dedicated voice recognition chip includes:
and identifying whether the duration of the frequency component in the audio signal reaches a preset duration or not through a special voice recognition chip, and if so, determining that the audio signal comprises the frequency component.
In the embodiment of the application, when the special voice recognition chip recognizes whether the audio signal provided by the microphone includes the frequency component corresponding to the public transport station, the special voice recognition chip can recognize whether the duration of the frequency component corresponding to the public transport station in the audio signal reaches the preset duration, and when the duration of the frequency component in the audio signal reaches the preset duration, the audio signal is determined to include the frequency component corresponding to the public transport station.
It should be noted that different types of public transportation stations have different corresponding frequency components.
For example, taking a subway station as an example, the subway station corresponds to 7 different frequency components, the 7 different frequency components correspond to corresponding preset durations respectively, and the preset durations corresponding to the different frequency components are different, the dedicated voice recognition chip respectively recognizes whether duration durations of the 7 frequency components corresponding to the subway station in the audio signal provided by the microphone reach the respective corresponding preset durations, and if the duration durations reach the respective preset durations, it is determined that the audio signal includes the frequency component corresponding to the subway station, that is, it is determined that the electronic device passes through the subway station.
In one embodiment, the recognizing, by a dedicated speech recognition chip, whether the duration of the frequency component in the audio signal reaches a preset duration includes:
(1) carrying out non-overlapping framing processing on the audio signal through a special voice recognition chip to obtain a plurality of audio frames;
(2) and carrying out Fourier transform on the audio frame through a special voice recognition chip, and recognizing whether the amplitudes of the frequency components in the continuous audio frame in the preset time reach the preset amplitudes according to the Fourier transform result, if so, determining that the duration of the frequency components in the audio signal reaches the preset time.
In the embodiment of the application, when identifying whether the duration of the frequency component in the audio signal reaches the preset duration, the dedicated voice identification chip firstly performs non-overlapping framing processing on the audio signal provided by the microphone to obtain a plurality of audio frames.
For example, referring to fig. 4, the dedicated speech recognition chip performs non-overlapping framing on the audio signal x (N) provided by the microphone, where each frame has a length of N, and performs co-framing to obtain m audio frames, where each audio frame may be represented as xm(n) of (a). Where non-overlapping framing may be colloquially understood as framing resulting in no overlapping portions between two adjacent audio frames.
After obtaining a plurality of audio frames by framing, the special voice recognition chip further performs Fourier transform on each audio frame obtained by framing, and recognizes whether the amplitude values of the frequency components corresponding to the public transport station in the continuous audio frames in the preset time length all reach the preset amplitude values according to the Fourier transform result, if so, the duration time of the frequency components in the audio signals is determined to reach the preset time length. The preset duration may be set by a person skilled in the art according to actual needs, and is not specifically limited in the embodiment of the present application.
For example, for audio frame xm(n) performing fast Fourier transform to obtain a corresponding Fourier transform result Xm(n)＝FFT[xm(n)]Then the frequency resolution of the Fourier transform is fsN, wherein fsN is the audio frame length, which is the sampling frequency of the audio signal. For any frequency component f, it is transformed into a Fourier transform result XmThe position in (n) is i ═ Nf/fsCan be represented as Xm(i) In that respect Then, for the frequency component f 'corresponding to the public transportation station, the amplitude of the frequency component f' is equal to
Wherein abs [ alpha ], [ alpha ]]Indicating that the absolute value is taken. For the frequency component f ', if the frequency component f' is in the amplitude of each frame of the continuous audio frame within the preset time period t
When the predetermined amplitude α is reached, the duration of the frequency component f' in the audio signal is determined to reach the predetermined duration t.
In one embodiment, identifying, by the processor, whether the audio signal is a preset audio signal corresponding to a public transportation station includes:
(1) calling a pre-trained audio recognition model corresponding to a preset audio signal through a processor;
(2) and identifying whether the audio signal is a preset audio signal corresponding to the public transport station according to the audio identification model.
It should be noted that, in the embodiment of the present application, an audio recognition model corresponding to a preset audio signal is trained in advance, and is configured to classify an input audio signal to be recognized, so as to obtain a classification result that the audio signal to be recognized is the preset audio signal, or obtain a classification result that the audio signal to be recognized is not the preset audio signal.
Illustratively, preset audio signals corresponding to public transport stations can be collected in advance, spectrogram of the preset audio signals is extracted to serve as a training sample, and the training is carried out according to the training sample by using a convolutional neural network to obtain an audio recognition model.
Correspondingly, when the processor identifies whether the audio signal is the preset audio signal corresponding to the public transport station, the processor can call the pre-trained audio recognition model corresponding to the preset audio signal, and input the audio signal provided by the special voice recognition chip into the audio recognition model for classification, so as to obtain the recognition result that the audio signal is the preset audio signal, or obtain the recognition result that the audio signal is not the preset audio signal.
In one embodiment, receiving, by a processor, an arrival alert request includes:
(1) detecting trigger information generated by public transport application through a processor, and providing a station arrival reminding interface according to the trigger information;
(2) and receiving the arrival reminding request through the arrival reminding interface.
It should be noted that, when the public transportation application is operated at the foreground, the processor may receive a display request for indicating the display of the riding code through the public transportation application, and display the riding code according to the display request, so that the user can quickly pass through a subway gate or enter a bus, etc. Accordingly, after the displayed ride code is scanned, the public transportation application will generate a trigger message indicating that the ride code has been scanned.
Correspondingly, the processor can detect the trigger information generated by the public transport application, if the trigger information is detected, the electronic equipment can be determined to enter a subway station or board a bus along with a user, the arrival reminding interface is provided at the moment, and the arrival reminding request is received through the arrival reminding interface.
In one embodiment, in order to ensure the accuracy of the arrival reminding, when the number of stations is consistent with the number of target stations, a preset arrival reminding operation is performed by a processor, and the preset arrival reminding operation includes:
(1) when the number of stations of the electronic equipment which pass through the public transport station is consistent with that of the target stations, acquiring a base station identifier of a base station which establishes mobile communication connection with the electronic equipment through a processor;
(2) determining the public transport station corresponding to the base station identifier through a processor according to the corresponding relation between the preset base station identifier and the public transport station;
(3) and when the public transportation station is the target public transportation station, executing preset arrival reminding operation through the processor.
In the embodiment of the application, when the processor identifies that the number of the stations of the electronic device which have passed through the public transportation station is consistent with the number of the target stations, the processor does not immediately execute the preset arrival reminding operation, but identifies the public transportation station actually arrived by the electronic device, and when the public transportation station actually arrived by the electronic device is consistent with the target public transportation station, the processor executes the preset arrival reminding operation.
When the fact that the number of stations of the electronic device which have passed through the public transport station is consistent with the number of target stations is recognized, the processor firstly acquires a base station identifier of a base station which establishes mobile communication connection with the electronic device, namely the base station identifier of the base station which provides network access service for the electronic device.
Then, the processor determines the public transportation station corresponding to the acquired base station identifier according to the corresponding relation between the preset base station identifier and the public transportation station, and the public transportation station is used as the public transportation station actually reached by the electronic equipment.
When determining that the public transportation station actually reached by the electronic device is the target public transportation station, the processor further identifies whether the public transportation station actually reached by the electronic device is the target public transportation station, and when the public transportation station actually reached by the electronic device is the target public transportation station, the processor executes a preset arrival reminding operation, which may specifically refer to the relevant description in the above embodiments, and is not described herein again.
Fig. 5 is another schematic flow chart of the arrival reminding method according to the embodiment of the present application. The arrival reminding method is applied to the electronic device provided by the application, the electronic device comprises a processor, a special voice recognition chip and a microphone, and as shown in fig. 5, the flow of the arrival reminding method provided by the embodiment of the application can be as follows:
in 201, the processor detects trigger information generated by the public transportation application and provides a station arrival reminding interface according to the trigger information.
It should be noted that, when the public transportation application is operated at the foreground, the processor may receive a display request for indicating the display of the riding code through the public transportation application, and display the riding code according to the display request, so that the user can quickly pass through a subway gate or enter a bus, etc. Accordingly, after the displayed ride code is scanned, the public transportation application will generate a trigger message indicating that the ride code has been scanned.
Correspondingly, the processor can detect the trigger information generated by the public transport application, and if the trigger information is detected, the electronic equipment can be determined to enter a subway station or board a bus along with a user, and at the moment, the arrival reminding interface is provided, so that the arrival reminding request is received through the arrival reminding interface.
In 202, the processor receives the arrival reminding request through the arrival reminding interface, and determines the target public transportation station needing arrival reminding according to the arrival reminding request.
For example, referring to fig. 2, the arrival reminding interface shown in fig. 2 includes all public transportation stations through which a public transportation route passes, that is, illustrated public transportation station 1 to public transportation station 9, and the processor may receive an arrival reminding request corresponding to a public transportation station according to an "alarm clock" control associated with any public transportation station by a user, where the arrival reminding request carries a station identifier (for example, a station name of the station) of the corresponding public transportation station.
After receiving the input arrival reminding request, the processor analyzes the station identifier carried by the arrival reminding request, and sets the public transport station corresponding to the station identifier as a target public transport station needing arrival reminding.
At 203, the processor obtains a target stop number for the public transportation stop that the electronic device needs to pass by to reach the target public transportation stop.
After determining the target public transportation station needing to be reminded of the arrival station, the processor further acquires the number of the target stations of the public transportation stations which are required to be passed by the electronic equipment to reach the target public transportation station.
The processor firstly acquires a base station identifier of a current base station which establishes mobile communication connection with the electronic equipment at present, and determines a public transport station corresponding to the current base station according to a preset corresponding relation between the base station identifier and the public transport station, and records the public transport station as the current public transport station.
It should be noted that the base station provides network access service for the electronic device, and the location of the electronic device is usually fixed, and when the electronic device establishes a mobile communication connection with a certain base station, the location of the electronic device can be determined. Based on this, in the embodiment of the application, the base station is associated with the public transportation station closest to the base station in advance, and the corresponding relationship between the base station identifier and the public transportation station is further established. The base station identifier is used to uniquely characterize the base station, and a person of ordinary skill in the art can select a parameter as the base station identifier according to actual needs, for example, in the embodiment of the present application, a cell identifier and a location area code are used as the base station identifier.
After the current public transport station is determined, the processor acquires pre-stored route information from the current public transport station to the target public transport station, and determines the number of target stations of the public transport stations which are required to pass by the electronic equipment to reach the target public transport station from the current public transport station according to the route information, the current public transport station and the target public transport station.
For example, for the public transportation route from the public transportation station 1 to the public transportation station 9 shown in fig. 2, assuming that the target public transportation station is the public transportation station 9, if the determined current public transportation station is the public transportation station 3, the processor may determine that the number of target stations of the public transportation stations that the electronic device needs to pass through to reach the target public transportation station is 6.
In 204, the dedicated speech recognition chip controls the microphone to capture an external audio signal.
After determining the number of target stations of the public transportation stations which are required to pass by when the electronic equipment reaches the target public transportation stations, the processor instructs the special voice recognition chip to start the station passing detection, namely, whether the electronic equipment passes the public transportation stations or not.
Correspondingly, the special voice recognition chip controls the microphone to collect external audio signals according to the instruction of the processor for station-crossing detection.
In 205, the dedicated voice recognition chip and the co-processor recognize the audio signal to obtain the number of stations that the electronic device has passed through the public transportation station.
The special voice recognition chip and the processor carry out station passing detection according to the collected audio signals, namely whether the collected audio signals are the audio signals passing through public transport stations is recognized, if yes, the electronic equipment is determined to pass through one public transport station, and therefore the number of stations of the electronic equipment passing through the public transport stations can be obtained.
For example, the dedicated voice recognition chip first recognizes whether the audio signal is an audio signal passing through a public transportation station, and when it is recognized that the audio signal is an audio signal passing through a public transportation station, the audio signal is provided to the processor, and the processor recognizes again whether the audio signal is an audio signal passing through a public transportation station, and if so, it is determined that the electronic device passes through a public transportation station.
For example, the dedicated voice recognition chip may determine whether the audio signal includes an audio feature of a public transportation station, and if so, the audio signal is an audio signal passing through the public transportation station; the processor can directly compare the audio signal provided by the microphone with the audio signal which is collected in advance and passes through the public transport station, and when the comparison between the audio signal provided by the microphone and the audio signal passes through the public transport station, the audio signal is judged to be the audio signal passing through the public transport station.
At 206, the processor obtains a base station identification of a base station establishing a mobile communication connection with the electronic device when the number of stations coincides with the number of target stations.
When the fact that the number of stations of the electronic device which have passed through the public transport station is consistent with the number of target stations is recognized, the processor firstly acquires a base station identifier of a base station which establishes mobile communication connection with the electronic device, namely the base station identifier of the base station which provides network access service for the electronic device.
At 207, the processor determines the public transportation station corresponding to the base station identifier according to the preset correspondence between the base station identifier and the public transportation station.
Then, the processor determines the public transportation station corresponding to the acquired base station identifier according to the corresponding relation between the preset base station identifier and the public transportation station, and the public transportation station is used as the public transportation station actually reached by the electronic equipment.
At 208, a preset arrival alert operation is performed by the processor when the public transportation station is the target public transportation station.
When the public transportation station which is actually reached by the electronic equipment is determined, the processor further identifies whether the public transportation station which is actually reached by the electronic equipment is the target public transportation station, and when the public transportation station which is actually reached by the electronic equipment is the target public transportation station, the processor executes preset arrival reminding operation.
