An earphone box, a charging detection method, a charging detection device, and a storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
The embodiment of the application provides a charging detection method of an earphone box, which is implemented based on a circuit structure of the earphone box, the circuit structure of the earphone box is shown in fig. 1, the earphone box comprises a controller 10, a detection circuit 11, a charging pin 12 and a power supply 13, the detection circuit is respectively connected with the controller, the power supply and the charging pin, the power supply is connected with the charging pin, and the power supply, the controller and the detection circuit are all grounded. The detection circuit can be an amplifier feedback circuit composed of an operational amplifier, a resistor, a capacitor and other electrical elements. The controller may be an MCU (micro controller Unit) chip. The power supply may include an LDO (Low Dropout Regulator) chip and a battery, and the battery may be a lithium battery or a secondary battery. The battery is connected with the charging pin through the LDO chip. The charging pin can be a charging probe or a charging gasket and the like.
The method detects the charging parameter value at the charging pin in real time through the detection circuit, judges the charging state corresponding to the charging pin according to the detected charging parameter value through the controller, and realizes real-time monitoring on the charging state of each charging pin in the charging box, so that a user can be timely found and reminded when abnormal charging occurs, and the condition that the electric quantity of an earphone is insufficient when the user uses the earphone due to poor contact of the charging pin is avoided.
Referring to fig. 2, the method specifically includes the following steps;
step 101: and acquiring the charging parameter value at the charging pin in the earphone box in real time.
After the earphone box starts to charge the earphones, the charging parameter value at each charging pin in the earphone box is obtained in real time through the detection circuit. In this embodiment, each charging pin is connected in parallel with a voltage-dividing resistor, the detected charging parameter value at the charging pin is a voltage value at two ends of the voltage-dividing resistor connected in parallel with the charging pin, and a ratio of the voltage value to the voltage-dividing resistor is a charging current flowing through the charging pin.
When a charging parameter value at a certain detection charging pin is detected, voltage values at two sides of a voltage-dividing resistor connected with the charging pin in parallel are detected through a detection circuit, a preset number of times is continuously detected, an average value of the voltage values detected by the preset number of times is calculated, and the average value is used as the charging parameter value at the charging pin detected at the time. The predetermined number may be 50 or 80.
And after the detection circuit detects the charging parameter value at the charging pin, the charging parameter value is transmitted to the controller. The controller stores the mapping relation among the identification information of the charging pins, the charging parameter values and the sampling time of the charging parameter values. The controller may store the charging parameter value and the corresponding sampling time within a time period closest to the current time, such as storing the charging parameter value and the corresponding sampling time within a time period of last 5 seconds, 1 minute, or 3 minutes.
Step 102: and determining the current charging stage according to the charging parameter value at the charging pin.
The charging process of the earphone box is generally divided into 4 stages, namely a pre-charging stage, a constant-current charging stage, a constant-voltage charging stage and a trickle charging stage. In the pre-charging stage, the charging current flowing through the charging pin is very small, and the charging current is gradually increased. The charging current flowing through the charging pin is kept constant in the constant current charging stage. The charging voltage at the charging pin is kept constant during the constant voltage charging phase, and the charging current slowly decreases. The headset is about to be fully charged during the trickle charge phase, where the charging current at the charging pin is small. When any one of the 4 charging stages of the earphone box is switched to the next stage, sudden drop of the charging current cannot be generated, and the sudden drop of the charging current can be generated only when the contact between the charging pin and the charging interface of the earphone is poor. The embodiment of the application refers to the sudden drop of the charging current as an abnormal charging state, and judges whether the charging pin is in the abnormal charging state in real time through the detection circuit and the controller, and the condition of poor contact of the charging pin is discovered in time.
After the charging parameter value at the charging pin is obtained through the operation in step 101, the current charging stage of the earphone box is determined according to the charging parameter value. In the embodiment of the application, a current charging parameter value of a charging pin is referred to as a first charging parameter value, and a last detected charging parameter value closest to the current charging pin is referred to as a second charging parameter value. Specifically, a sum of the first charging parameter value at the charging pin and a preset error value is calculated, and the preset error value may be 10mv or 30mv, and the like. And comparing the calculated sum value with the second charging parameter value, and if the sum value is greater than the second charging parameter value, determining that the current charging stage is in a pre-charging stage or a constant-current charging stage.
If the first charging parameter value is smaller than the second charging parameter value, the charging parameter value at the charging pin is detected again at intervals of a first preset time length, and the first preset time length can be 50ms or 60 ms. The re-detected charge parameter value becomes the new first charge parameter value at this time, and the previous first charge parameter value becomes the new second charge parameter value. And calculating a difference value between the current second charging parameter value and the current first charging parameter value, comparing the difference value with a preset constant voltage threshold value, and determining that the current charging stage is in a constant voltage charging stage if the difference value is smaller than the preset constant voltage threshold value. The preset constant voltage threshold may be 20mv or 25mv, etc. The embodiment of the application does not limit the specific value of the preset constant voltage threshold, and the earphone box can be flexibly configured according to the setting of the charging current of the earphone box in practical application.
And if the first charging parameter value at the charging pin is smaller than the preset trickle threshold value, determining that the charging pin is in a trickle charging stage currently. The preset trickle threshold may be 17mv or 20mv, and the specific value of the preset trickle threshold is not limited in the embodiments of the present application, and the trickle threshold may be flexibly configured according to the setting of the charging current in the trickle charging stage of the headphone case in practical applications.
Step 103: and determining the current charging state of the charging pin according to the current charging stage and the charging parameter value at the charging pin.
In the embodiment of the application, the threshold values corresponding to different charging stages and used for judging the charging state, such as a first preset threshold value corresponding to a pre-charging stage or a constant-current charging stage and a second preset threshold value corresponding to a constant-voltage charging stage, are preset in the controller. The first preset threshold may be 10mv or 12mv, and the like, and the value of the first preset threshold is not limited in the embodiment of the present application, and in practical application, the first preset threshold may be flexibly configured according to the setting of the charging current in the pre-charging stage or the constant-current charging stage. The second preset threshold may be 30mv or 50mv, and the like, and the value of the second preset threshold is not limited in the embodiment of the present application, and the second preset threshold may be flexibly configured according to the setting of the charging current in the constant voltage charging stage in practical application.
If the step 102 determines that the earphone box is currently in the pre-charging stage or the constant current charging stage, a first preset threshold corresponding to the pre-charging stage or the constant current charging stage is obtained, a difference value between a second charging parameter value and a first charging parameter value is calculated, the difference value is compared with the first preset threshold, and if the difference value is larger than the first preset threshold, it is determined that the charging pin is currently in an abnormal charging state.
When the difference value between the second charging parameter value and the first charging parameter value is larger than the first preset threshold value, the voltage values of two ends of the divider resistor connected with the charging pin in parallel are reduced, the reduction degree is overlarge, the voltage value of the divider resistor is reduced, the resistance of the divider resistor is unchanged, and therefore the current flowing through the divider resistor is reduced. The current flowing through the voltage-dividing resistor is equal to the current flowing through the charging pin, so that the charging current flowing through the charging pin is determined to be reduced, and the reduction degree is overlarge. And at this time, the charging pin is in a pre-charging stage or a constant-current charging stage, and under a normal condition, the charging current in the two stages should not drop, so that it can be determined that the sudden drop of the charging current is probably caused by poor contact of the charging pin at this time, and therefore it is determined that the charging pin is currently in an abnormal charging state.
If the earphone box is determined to be in the constant voltage charging stage currently in step 102, a second preset threshold corresponding to the constant voltage charging stage is obtained, a difference value between a second charging parameter value and a first charging parameter value is calculated, the difference value is compared with the second preset threshold, and if the difference value is larger than the second preset threshold, it is determined that the charging pin is in an abnormal charging state currently.
When the difference value between the second charging parameter value and the first charging parameter value is larger than the second preset threshold value, the voltage values of two ends of the divider resistor connected with the charging pin in parallel are reduced, the reduction degree is overlarge, the voltage value of the divider resistor is reduced, the resistance of the divider resistor is unchanged, and therefore the current flowing through the divider resistor is reduced. The current flowing through the voltage-dividing resistor is equal to the current flowing through the charging pin, so that the charging current flowing through the charging pin is determined to be reduced, and the reduction degree is overlarge. And at this time, the charging pin is in a constant voltage charging stage, and normally, the charging current in the stage should be slowly reduced, so that it can be determined that the sudden reduction of the charging current at this time is probably caused by poor contact of the charging pin, and therefore, it is determined that the charging pin is currently in an abnormal charging state.
If it is determined in step 102 that the earphone box is currently in the trickle charge stage, since the trickle charge stage is a micro-current charge stage, the electric quantity of the earphone is nearly full, and the influence of poor contact of the charging pin on the electric quantity of the earphone is not great, it may not be determined whether the charging state of the charging pin in the trickle charge stage is an abnormal charging state in the embodiment of the present application.
In this embodiment of the application, in the pre-charge stage or the constant current charge stage, according to the above manner, when it is determined that the difference between the second charge parameter value and the first charge parameter value is greater than the first preset threshold value, it is immediately determined that the charge pin is currently in the abnormal charge state. The current abnormal charging state may also be determined, the charging pin may be continuously detected, and if the difference between the second charging parameter value and the first charging parameter value is detected to be still greater than the first preset threshold within a time period greater than or equal to a second preset time period, the current abnormal charging state of the charging pin may be determined. The second preset time period may be 5 seconds or 8 seconds, etc.
By continuously detecting the second preset time length, if the difference value between the second charging parameter value and the first charging parameter value in the second preset time length is continuously larger than the first preset threshold value, that is, the charging state of the charging pin cannot be restored to the normal state in the second preset time length, then determining that the charging pin is currently in the abnormal charging state. Therefore, the condition of misjudging to be the abnormal charging state can be reduced, and the accuracy of the charging state is improved.
Similarly, in the constant-voltage charging stage, it may be determined that the charging pin is currently in the abnormal charging state immediately when the difference between the second charging parameter value and the first charging parameter value is greater than the second preset threshold value in the manner described above. The current abnormal charging state may also be determined, the charging pin may be continuously detected, and if the difference between the second charging parameter value and the first charging parameter value is detected to be still greater than the second preset threshold within a time period greater than or equal to the second preset time period, the current abnormal charging state of the charging pin may be determined.
As shown in fig. 3, the circuit structure of the earphone box further includes an alarm device 14, and the alarm device 14 is connected to the controller. If the present embodiment determines that the current charging state of the charging pin is the abnormal charging state through the operations of the above steps 101-103, the controller controls the alarm device 14 to send out the alarm prompt information for indicating that the charging pin is abnormal.
The alarm device 14 may comprise a warning light and/or a voice player. And when the current charging state of a certain charging pin is judged to indicate an abnormal charging state, lightening a warning lamp corresponding to the charging pin. And/or playing alarm voice information corresponding to the charging pin through a voice player, wherein the alarm voice information comprises identification information and abnormal prompt information corresponding to the charging pin. The identification information corresponding to the charging pin may be a number corresponding to the charging pin, such as 001, 002, etc. Or the identification information may be the corresponding relative position of the charging pin, such as the left side or the right side. For example, the alarm voice message may be "poor contact of the charging pin corresponding to the 001-th earphone", or may be "poor contact of the charging pin corresponding to the left earphone", or the like.
After seeing that the warning light on the earphone box is lighted, or hearing the alarm voice information played by the earphone box, a user can know that the charging pin corresponding to the warning light is in poor contact, or can know that the charging pin corresponding to the identification information in the alarm voice information is in poor contact. The user can eliminate the poor contact condition between the charging pin and the earphone by adjusting the position of the earphone corresponding to the charging pin.
