Example 1
According to an embodiment of the present invention, as shown in fig. 1, there is provided a method for preventing lost, where the method includes:
step S101, continuously judging whether sound information of a target main body to be prevented from losing is acquired;
in this embodiment, the target subject may be any target subject that needs to be prevented from losing and can make a sound, for example, a child, an elderly person, an adult person needing to be monitored, a pet, and the like.
In this embodiment, a mobile terminal carried by the user/guardian may be used to continuously determine whether sound information of the target subject to be prevented from losing is collected, so as to determine whether the target subject is still at the side of the user/guardian. When the sound information of the target main body is not acquired for a period of time, the target main body is possibly out of the user/guardian, and the user/guardian needs to be warned to pay attention to the target main body in time so as to prevent the user/guardian from losing.
In order to reduce the energy consumption of the system while effectively judging the sound information of the target subject, in this embodiment, the continuously judging whether the sound information of the target subject to be prevented from losing is collected includes: sequentially judging whether sound information of a target main body to be prevented from losing is acquired or not at a plurality of preset time points; the preset time points are time points in a time period formed from the current time to the time corresponding to the preset time threshold.
For example, if the preset time threshold is 10 seconds, counting from the current time, selecting a plurality of time points from the time period of 10 seconds, and respectively judging whether the sound information of the target subject to be prevented from losing is acquired at the time points. For example, the above determination is set to be performed every 2 seconds, and the information on which the determination is based may be sound information acquired in the first 2 seconds of the current time.
The preset time threshold may be set or modified according to the actual requirement of the user, which is not particularly limited in this embodiment.
In order to more simply and effectively determine whether to collect the sound information of the target subject, in this embodiment, the sequentially determining, at a plurality of preset time points, whether to collect the sound information of the target subject to be prevented from losing includes: the following operations are performed at each of the preset time points to obtain the values of the preset number of times parameter: judging whether sound information of the target main body is acquired in a preset time period before the preset time point; when the sound information of the target main body is acquired in the preset time period before the preset time point, adding 1 to the value of the preset frequency parameter; wherein, the initial value of the preset times parameter is 0; judging whether the numerical value of the preset times parameter is 0 or not; and when the value of the preset times parameter is 0, determining that the sound information of the target main body is not acquired beyond the preset time threshold.
The preset frequency parameter is used for indicating the frequency of collecting the sound information of the target main body in a certain time period.
In this embodiment, the determining whether the sound information of the target subject is collected in a preset time period before the preset time point includes: performing sound collection and processing operation in real time to obtain sound information to be detected; comparing the to-be-detected sound information in the preset time period before the preset time point with pre-stored reference sound source information to judge whether the to-be-detected sound information in the preset time period before the preset time point contains the reference sound source information or not; the reference sound source information is acquired and processed based on the sound of the target main body; when the reference sound source information is contained in the sound information to be detected in the preset time period before the preset time point, determining that the sound information of the target main body is acquired in the preset time period before the preset time point.
Further, the method for determining whether the sound information of the target subject is collected in the preset time period before the preset time point according to the embodiment further includes: when the reference sound source information is not contained in the sound information to be detected in the preset time period before the preset time point, determining that the sound information of the target main body is not collected in the preset time period before the preset time point.
Specifically, the mobile terminal of the user/guardian performs the recording operation in real time, and performs processing such as filtering on the sound collected by the recording to obtain the sound information to be detected. When the anti-lost function of the scheme is used initially, timing is started from the moment of starting recording, and whether sound information of a target main body to be prevented from being lost is acquired is judged every 2 seconds. When the time of 2 seconds is up, comparing the sound information to be detected obtained in the 2 seconds with the pre-stored reference sound source information to judge whether the reference sound source information is contained in the sound information to be detected obtained in the 2 seconds, and when the reference sound source information is contained in the sound information to be detected obtained in the 2 seconds, determining that the sound information of the target main body is collected in the 2 seconds, namely, indicating that the target main body is at the side of a user/guardian in the 2 seconds, wherein the value of the preset frequency parameter is added by 1; when the reference sound source information is not contained in the sound information to be detected obtained within 2 seconds, determining that the sound information of the target main body is not collected within 2 seconds, namely indicating that the target main body does not sound within 2 seconds or is not at the side of the user/guardian, and keeping the value of the preset frequency parameter unchanged.
The above operation is performed at every 2 seconds, and when a preset time threshold is reached, for example, 10 seconds from the recording start time, the value of the preset number parameter is obtained, and whether the value of the preset number parameter is 0 is determined. When the value of the preset frequency parameter is 0, the fact that the sound information of the target main body is not acquired within 10 seconds is indicated, the target main body is possibly not at the side of the user/guardian, and at the moment, an alarm operation is carried out to remind the user/guardian of timely paying attention to the target main body; when the value of the preset number of times parameter is not 0, it indicates that the sound information of the target subject is collected in the 10 seconds, specifically, the sound information of the target subject collected several times in the 10 seconds can be determined according to the value of the preset number of times parameter, that is, the target subject is nearby the user/guardian in the 10 seconds, at the moment, no alarm is needed, and the operation is continuously repeated in the next 10 seconds. When the above operation is repeatedly performed for the next 10 seconds, the timing start timing is the current timing.
In this embodiment, the specific time of the sound information of the target subject may be further recorded and stored for the user/guardian to check, so that the user/guardian can more conveniently and effectively master the state/movement of the target subject.
In order to obtain the sound information to be detected more conveniently and effectively, in this embodiment, the performing the sound collection and processing operation in real time to obtain the sound information to be detected includes: and carrying out sound collection and processing operation in real time by adopting a mobile terminal, and obtaining and storing the sound information to be detected.
In this embodiment, the mobile terminal is a mobile terminal carried by the user/guardian, for example, may be a mobile terminal such as a mobile phone, a tablet, or an intelligent bracelet of the user/guardian.
In order to promote the memory space and make the system work in an efficient state, the method in this embodiment further includes: receiving an information deletion request; and deleting the sound information to be detected based on the information deleting request.
That is, in this embodiment, the user may delete the stored sound information to be detected at any time, so as to avoid unnecessary memory consumption.
In order to more intelligently detect the storage state of the current system and facilitate the user operation, before the information deletion request is received, the method of the embodiment further includes: judging whether the stored sound information to be detected exceeds a preset threshold value or not; when the stored sound information to be detected exceeds the preset threshold value, displaying inquiry information; the inquiry information is used for inquiring whether the user performs deleting operation on the stored sound information to be detected; then, the receiving the information deletion request includes: and receiving an information deleting request sent by the user based on the inquiry information.
Specifically, the system may detect the size of the stored sound information to be detected at a preset time point, for example, the function described in the present scheme may be manufactured as a specific APP, and when the APP is started each time, the system automatically detects the size of the stored sound information to be detected to determine whether the size exceeds a preset threshold. When the size of the stored sound information to be detected exceeds the preset threshold, the automatic pop-up dialog box inquires of the user whether the stored sound information to be detected is deleted. When the user selects 'yes', the system automatically deletes the stored sound information to be detected; when the user selects "no", the system retains the stored sound information to be detected.
The sound information to be detected is cached in the mobile terminal of the user in the form of an audio file.
In order to accurately delete the sound information to be detected and improve user experience, the information deletion request in this embodiment includes: a selected time range; and deleting the sound information to be detected based on the information deletion request, wherein the deleting comprises the following steps: and deleting the sound information to be detected in the selected time range based on the information deleting request.
In this embodiment, the user may select a time range to delete the to-be-detected sound information, and only delete the to-be-detected sound information that is not needed by the user, but retain the to-be-detected sound information that is needed by the user.
In order to further effectively prevent the loss of the target subject, the method according to this embodiment further includes: continuously judging whether the distance between the target main body and the mobile terminal is larger than a preset distance threshold value; and when the distance between the target main body and the mobile terminal is greater than the preset distance threshold, carrying out anti-lost alarm.
Specifically, the system may further continuously detect a distance between the target subject and the mobile terminal of the user/guardian, and when the distance is greater than a preset distance threshold, for example, when the distance is greater than 10 meters, perform an alarm operation to remind the user/guardian to pay attention to the target subject in time, so as to prevent the target subject from losing.
And step S102, when the sound information of the target main body is not acquired beyond a preset time threshold, anti-lost alarm is carried out.
For example, when the sound information of the target subject is not collected for more than 10 seconds, the target subject may not be at the side of the user/guardian, and the user/guardian needs to be alerted to pay attention to the target subject in time to prevent the target subject from losing.
In order to further facilitate the user operation and improve the user experience, the method in this embodiment further includes: receiving a closing alarm request; and stopping the anti-lost alarm based on the closing alarm request.
Specifically, when the system gives an alarm, the user/guardian can send a request for closing the alarm to the system at any time based on a preset key or a preset operation, and when the system receives the request, the anti-lost alarm is stopped.
The following further describes the anti-lost method applied to children according to the embodiment in detail by taking actual operations in actual application as an example:
as shown in fig. 2, the anti-lost method applied to children in this embodiment includes:
s1, starting a child anti-lost APP on a mobile terminal of a user/guardian.
S2, prompting a user to record a 60-second sound source of a template child through the APP, performing audio pre-judgment after the user records the sound source for 60 seconds, and when only one person' S voice is in the pre-judgment audio, processing (such as filtering and other basic processing) and storing the audio to obtain the reference sound source information.
S3, setting or modifying the preset time threshold in the step S102, namely setting or modifying the sound loss time interval, namely when the number of seconds of reference sound source information which is not stored in the surrounding environment sound in advance is found, an alarm is needed to prompt a user/guardian.
S4, after the acquisition of the reference sound source information and the setting of the preset time threshold are completed, an anti-lost reminding switch in the APP can be turned on. After the switch is turned on, the recording device on the mobile terminal starts recording and continuously records, and sound information to be detected is obtained after the recording is filtered and the like.
S5, recording and extracting every two seconds, namely, recording and extracting every 2n seconds, wherein the extracted recording information is (2 n-2 n) seconds, namely, the sound information to be detected is obtained 2 seconds before the time point.
S6, comparing the extracted sound information to be detected with the reference sound source information obtained in the S2, wherein a sound comparison algorithm can be specifically adopted for comparison to obtain a comparison result:
if the sound information to be detected within 2 seconds contains reference sound source information after comparison, recording a specific period of (2 n-2 n) seconds, adding 1 to the numerical value of a preset frequency parameter, and marking a comparison result as true;
if the comparison results of every two seconds in (2 n-X-2 n-2) seconds are determined to be not contained in the sound information to be detected within 2 seconds after comparison, if the number of the comparison results=true is greater than or equal to 1, namely the numerical value of the preset frequency parameter is greater than or equal to 1, the process is ended; if the comparison result=true is less than 1, the mobile terminal starts ringing or alarming, and the user can manually close the reminding at any time during ringing.
And S7, if the user turns off the anti-lost reminding switch in the child anti-lost APP, the recording device of the mobile terminal stops recording.
S8, checking and judging the size of the audio file cache when the child anti-lost APP is started each time, inquiring whether the user performs deletion if the stored audio file size exceeds a threshold set by the user, and performing the deletion action of the audio cache file according to the user operation.
