The embodiment of the invention provides a wireless earphone in-box detection method and device and a wireless earphone charging box, which not only save power consumption in the use process, but also improve the accuracy of a detection result to a certain extent, and are beneficial to improving the product performance and improving the user experience.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a wireless headset in-box detection method according to an embodiment of the present invention. The method comprises the following steps:
s110: acquiring distance information which is acquired by a distance sensor arranged on the side wall of a charging box shell and corresponds to a current obstacle;
it should be noted that, when the charging box is produced, a proximity sensor (proximity sensor) is arranged on a side wall of the charging box housing in advance, and since distance information acquired by the proximity sensor is not affected by an external magnetic field, acquired data is accurate. When detecting wireless earphone in this application and whether going into the box, gather the current barrier of the detected signal that reflection distance sensor in the box of charging and the distance information between the distance sensor through distance sensor, wherein, the current barrier in this embodiment is the earphone when the earphone goes into the box, and the current barrier is the lateral wall of the box of charging when the box of charging is empty.
S120: judging whether the distance information meets a preset condition, if so, entering S130; wherein the preset condition is set according to the condition that the charging box is empty;
s130: and determining that the earphone is placed in the box.
Specifically, in this application, when producing the box that charges, calibrate the blank box in advance, also adopt distance sensor to measure the blank box distance information of earphone when not in the box that charges in addition to confirm the preset condition of judgement earphone when in the box according to this blank box distance information, also when measured distance information satisfies this preset condition, say that the earphone goes into the box. In the user use, corresponding distance information can be gathered to the distance sensor who sets up in the box that charges, carries out the analysis to this distance information according to the preset condition that prestores, judges whether this distance information satisfies preset condition, when this distance information satisfies preset condition, determines the earphone and goes into the box to carry out operations such as charging to the earphone.
For example, when the distance sensor is an ultrasonic sensor, the distance information acquired by the ultrasonic sensor is a distance value between the ultrasonic sensor and an obstacle, and in the case of an empty box, a preset distance range (a, B) is determined through measurement, and the preset condition is that when the acquired distance value is smaller than a lower limit value of the preset distance range, it indicates that an object exists in the current box, and the earphone is determined to be in the box.
The embodiment of the invention provides a wireless earphone in-box detection method, which comprises the following steps: acquiring distance information which is acquired by a distance sensor arranged on the side wall of a charging box shell and corresponds to a current obstacle; judging whether the distance information meets a preset condition, if so, determining that the earphone is put into a box; wherein the preset condition is set according to when the charging box is empty. It is thus clear that this application gathers the distance information of current barrier through setting up the distance sensor on the box casing lateral wall that charges to confirm whether the earphone goes into the box according to distance information and preset condition, because distance sensor can not receive the influence of external magnetic field, so this application not only can practice thrift the consumption, can also improve the degree of accuracy of testing result to a certain extent, be favorable to improving product property ability, promote user experience.
On the basis of the above embodiments, the embodiment of the present invention further provides a method for detecting the presence of a wireless headset in a box, which is specifically shown in fig. 2. The embodiment further explains and optimizes the scheme, which specifically comprises the following steps:
s200: detecting whether a box cover of the charging box is opened or not, if so, entering S210;
it should be noted that, in order to further save the power consumption, the state of the lid of the charging box can be detected in this embodiment, and since the wireless headset needs to be placed into the charging box after the lid of the charging box is opened when the wireless headset is placed into the charging box, when the lid of the charging box is opened, it indicates that the user may have a need to charge the wireless headset, and then the distance sensor inside the charging box is controlled to perform data acquisition.
S210: acquiring distance information which is acquired by a distance sensor arranged on the side wall of a charging box shell and corresponds to a current obstacle;
specifically, the distance sensor in this embodiment may specifically be an optical sensor, and the corresponding specific process of S210 may be:
acquiring a light energy value which is collected by a light sensor arranged on the side wall of a charging box shell and reflected by a current barrier;
it can be understood that, since the data collected by the light sensor is the light energy value of the reflected light after the outgoing light returns through the obstacle, the distance between the current obstacle and the light sensor is indirectly reflected through the light energy value, and the light sensor has the advantages of high effect speed and high sensitivity, so that the detection accuracy can be further ensured. The optical sensor in the present application may specifically adopt a laser sensor or an infrared sensor, and the present application is not particularly limited. Of course, besides the optical sensor, other distance sensors, such as an ultrasonic sensor, may be used in practical applications, and the specific determination may be made according to practical needs.
S220: judging whether the distance information meets a preset condition, if so, entering S230, and if not, entering S240;
further, when the distance sensor employs an optical sensor, the process of determining whether the distance information satisfies the preset condition in S220 is as follows:
and judging whether the light energy value is larger than the upper limit value of the preset light energy range, if so, meeting the preset condition, and entering S230.
Specifically, when the charging box is produced, the light energy value of the empty box is collected by the light sensor in advance, a preset light energy range is determined according to the light energy value of the empty box, and a preset condition of the earphone in the box is determined and judged according to the preset light energy range.
For example, if the optical energy value of the empty cassette collected during calibration of the empty cassette is X, Y ═ X-20 is set as the lower limit of the preset optical energy range, Z ═ X +20 is set as the upper limit of the preset optical energy range, and the upper and lower limits of the preset optical energy range may be written into the flash memory.
In the process that a user uses the charging box, when the opening of a box cover of the charging box is detected, the optical sensor is controlled to collect data, and an optical energy value collected by the optical sensor is obtained, for example, the optical energy value is m, whether the m is larger than an upper limit value Z of a preset optical energy range is judged, when the m is larger than the Z, the returned optical energy value is larger, the earphone is put into the box, and when the optical energy value m is within the preset optical energy range, the earphone is taken out of the box.
Further, the method may further include:
and modifying the upper threshold and the lower threshold of the register corresponding to the optical sensor according to the light energy value and a preset modification rule, and clearing an interrupt flag bit in the optical sensor.
Specifically, in the process of acquiring data by the optical sensor, interruption is generated according to the upper threshold value and the lower threshold value of the register to output corresponding optical energy values, so that the upper threshold value and the lower threshold value of the register of the optical sensor can be modified according to the optical energy values output when interruption is currently generated and a preset modification rule, and meanwhile, the interruption flag bit generating the interruption is cleared, so that the optical sensor continues to acquire data.
Further, the process of modifying the upper and lower thresholds of the register corresponding to the optical sensor according to the light energy value and the preset modification rule may specifically be:
when the light energy value is within the preset threshold range, taking the sum of the light energy value and the lower limit of the preset threshold range as the upper threshold value of a register corresponding to the light sensor, and taking the difference between the light energy value and the lower limit of the preset threshold range as the lower threshold value of the register;
when the light energy value is less than or equal to the lower limit of the preset threshold range, taking the sum of the light energy value and the lower limit of the preset threshold range as the upper threshold value of the register, and taking 0 as the lower threshold value of the register;
when the light energy value is larger than or equal to the upper limit of the preset threshold range, the upper limit of the preset threshold range is used as the upper threshold value of the register, and the difference between the light energy value and the lower limit of the preset threshold range is used as the lower threshold value of the register.
Specifically, the optical energy value of the optical sensor read when the optical sensor is interrupted is m, when the upper and lower thresholds of the register of the optical sensor are modified according to the optical energy value m, the upper and lower thresholds of the register can be modified according to a predetermined preset threshold range (e.g., (20,235)), and it can be specifically determined whether the optical energy value m at this time is within the preset threshold range, if 20< m <235, m-20 is used as the lower threshold value of the register, m +20 is used as the upper threshold value of the register, and the threshold value of the register is modified; if m is less than or equal to 20, taking 0 as the upper threshold value of the register, taking m +20 as the upper threshold value of the register, and modifying the threshold value of the register; if m is larger than or equal to 235, taking m-20 as the lower threshold value of the register, taking 235 as the upper threshold value of the register, and modifying the threshold value of the register. It should be noted that the preset threshold range is not limited to (20,235), and may be other specific ranges, which may be determined according to the actual situations of the charging box and the optical sensor, and the application is not particularly limited.
S230: determining that the earphone is placed in the box;
specifically, after it goes into the box to determine the earphone, can also control the power and charge for the earphone to control the suggestion device that sets up on the box that charges and send first prompt information, so that the suggestion user is charging for the earphone, wherein, suggestion device can be for the warning light, for example the warning light lights when charging for the earphone.
S240: and determining that the earphone is placed in the box.
Specifically, after determining that the earphone goes out of the box, the power supply can be controlled to be turned off, so that the earphone is stopped being charged, and meanwhile, the prompt device can be controlled to be turned off, for example, the prompt lamp is controlled to be turned off.
It should be further noted that, in order to further improve the detection accuracy, in the above step S210, the process of acquiring the distance information corresponding to the current obstacle, acquired by the distance sensor arranged on the side wall of the charging box housing, may specifically be further:
acquiring N pieces of distance information corresponding to the current obstacle, which are continuously acquired by a distance sensor arranged on the side wall of a charging box shell, wherein N is an integer not less than 2;
then, the corresponding process of determining whether the distance information satisfies the preset condition in S220 may specifically be:
and judging whether the N pieces of distance information all meet preset conditions.
Specifically, N distance information collected by the distance sensor can be continuously acquired, and the earphone is determined to enter the box when the N distance information meets the preset condition, so that the measurement accuracy is improved. For example, when the distance sensor is an optical sensor, the optical energy value corresponding to N continuous interruptions of the optical sensor is obtained, and when the N optical energy values are all larger than the upper limit value of the preset optical energy range, it is determined that the earphone is put into the box. N may be specifically 2, and of course, specific numerical values thereof may be determined according to actual needs, and the present application is not particularly limited.
In addition, whether the earphone is taken out of the box is judged, specifically, the earphone is determined to be taken out of the box when the distance information acquired currently is judged not to meet the preset condition and the distance information acquired last time meets the preset condition, and therefore detection accuracy is improved.
