The embodiment of the invention provides a calibration method of a Bluetooth headset.
Referring to fig. 2, fig. 2 is a flowchart illustrating a calibration method of a bluetooth headset according to a first embodiment of the present invention.
In this embodiment, the calibration method for the bluetooth headset includes the following steps:
step S10, when detecting an earphone calibration instruction, determining an earphone to be calibrated according to the earphone calibration instruction, acquiring each infrared light value of the earphone to be calibrated in a wearing state, and generating a first infrared light value set;
in order to improve the cruising ability of the TWS earphone, an infrared proximity sensor is added on the TWS earphone, the wearing state of the earphone is identified through the infrared proximity sensor, and the earphone is automatically paused or controlled to enter a low power consumption mode when the condition that a user takes off the earphone is detected. However, wearing habit differences of different people, skin color differences and damage to the infrared sensor lens due to long-term use of the earphone cause reduction of the wearing state identification accuracy of the earphone based on the infrared sensor. In order to solve the problems, the invention can calculate and determine the latest infrared light threshold value of the earphone to be calibrated based on the first infrared light value set of the earphone to be calibrated in a wearing state and the second infrared light value set of the earphone to be calibrated in an unworn state, thereby providing a method for a user to calibrate the infrared light threshold value of the Bluetooth earphone by himself, improving the measurement sensitivity of an infrared sensor of the Bluetooth earphone and improving the wearing state identification accuracy of the Bluetooth earphone. Specifically, the calibration method of the Bluetooth headset is applied to the Bluetooth headset, and the Bluetooth headset comprises a calibration module and an infrared sensor. In this embodiment, the calibration module is used as an execution main body. The infrared sensor in a TWS headset consists of two devices, namely a radiation source for emitting light pulses and a photodiode for converting the received infrared energy into digital values. When infrared light from the radiation source hits an object block, the remaining infrared light, except for being absorbed by the object, is reflected to the photodiode, which converts the infrared energy into a digital Value IR _ Value. Comparing the value with a high threshold and a low threshold which are arranged in the infrared sensor, and if the value is larger than a set High Threshold (HT), the infrared sensor is considered to be close to the object, namely the TWS earphone is in a wearing state; if the value is less than the set Low Threshold (LT) the infrared sensor is considered to be far away from the object, i.e. the TWS headset is shown in an unworn state. Namely, wearing state: IR _ Value > HT; the non-wearing state: IR Value < LT. In order to facilitate the user to calibrate the infrared sensor by himself, the touch chip is registered in the MCU to interrupt the pin, so that the user can start the calibration mode of the earphone by pressing the earphone touch sensing piece for a long time. In a specific embodiment, after the step of determining the headset to be calibrated according to the headset calibration instruction when the headset calibration instruction is detected, the method further includes: sending a calibration reminding message to a user through an earphone or a terminal in communication connection with the earphone to be calibrated so that the user can wear and take off the earphone to be calibrated; when detecting that a user wears the earphone, acquiring and storing infrared light values of the earphone to be calibrated in a wearing state; and when the user is detected to take off the headset, acquiring and storing each infrared light value of the headset to be calibrated in an unworn state. The right earphone calibration mode can be started by long pressing of the left earphone touch control induction sheet. The left earphone is used for prompting that the right earphone is worn through voice, or a reminding message for prompting that the right earphone is worn through a terminal connected with the Bluetooth earphone in a communication mode or the voice is used for prompting that the right earphone is worn by a user. Upon detecting that the user wears the right headphone, a value converted by the photodiode, i.e., an infrared light value, may be collected once every 20ms, generating a first set of infrared light values. In further embodiments, in order to improve accuracy of the infrared light threshold, the step of acquiring each infrared light value of the headset to be calibrated in a wearing state and generating a first infrared light value set specifically includes: acquiring each infrared light value of the earphone to be calibrated in a wearing state, and judging whether an invalid value which does not belong to a preset range exists in each infrared light value of the earphone to be calibrated in the wearing state; and if the invalid value exists, deleting the invalid value in each infrared light value of the earphone to be calibrated in the wearing state, and generating the first infrared light value set. That is, the value of the infrared sensor in the state of not being close to the skin at the start of wearing and immediately before the end of taking off is close to 0 or less than 10, which is an invalid value.
Step S20, acquiring each infrared light value of the headset to be calibrated in an unworn state as a second infrared light value set;
in this embodiment, when it is detected that the user does not wear the right headphone, a value converted by the photodiode, that is, an infrared light value, may be collected once every 20ms, and a second infrared light value set is generated.
Step S30, calculating and determining the calibrated infrared light threshold of the headset to be calibrated based on a preset calculation rule, the first infrared light value set, and the second infrared light value set, and completing updating the headset infrared light threshold.
In this embodiment, the average value of the first infrared light value set and the average value of the second infrared light value set may be calculated, and then the average value of the two average values is used as the maximum infrared light threshold. Or based on the acquisition time point, setting each infrared value in the first infrared value set and each infrared value in the second infrared value set as corresponding points, and calculating the average value of each corresponding point. The calibrated infrared light threshold is determined based on the average value of each corresponding point. Specifically, the right headphone calibration will be described as an example. If the left earphone is worn, the TOUCH control interrupt can be triggered by LONG pressing of the left earphone TOUCH control induction sheet for 5s, and meanwhile, the right earphone is put into a box through the voice prompt of the left earphone, and the TOUCH control chip feeds back an interrupt event INT _ LONG _ TOUCH to the MCU end; after receiving the interrupt event, the left earphone MCU end sends a fixed data packet to the right earphone through BLE, namely, sends a prompt message to the right earphone; the right earphone analyzes the data packet sent by the left earphone after receiving the data packet; after the right earphone analyzes the mark for starting the calibration of the infrared sensor, the infrared sensor enters a calibration mode, and a mark for successful receiving is sent to the left earphone; after the left earphone receives the correct information fed back by the right earphone, prompting a reminding message of 'starting to calibrate the right earphone' and 'please wear the right earphone' by voice; the right earphone always acquires the value converted by the photodiode in the wearing process, and after the setting is stable, a complete wearing mark of the right earphone is sent to the left earphone through BLE; after the left earphone receives the mark that the right earphone is completely worn, the voice prompts 'please take off the right earphone'; collecting the value converted by the broadcasting diode all the time in the process of picking the right earphone, and stopping data collection when the value is stable or almost approaches to 0, and sending a calibration end mark to the left earphone; and after the left earphone receives the right earphone calibration end mark, the user is prompted by voice to 'end the right ear calibration'. After the right earphone is completely worn, the value is the maximum value _ max in the calibration process, the value is taken as a symmetrical point, symmetrical effective values recorded in the wearing and taking-off processes are compared and subtracted, if the difference value range is within +/-10, the two values are taken as effective values, the average value of the two values is taken as a new recorded value _ new, and the average value of the value _ max and the n values _ new is taken as a high threshold value. Namely, in the wearing process, the infrared light value is gradually increased, in the picking process, the infrared light value is gradually decreased to finish wearing the earphone as a peak point, the wearing process and the infrared light value in the picking process form a symmetrical relation, and the collecting time point is used as an associated identifier. And reducing a fixed value (different infrared chips have different values) on the basis of the high threshold value to be used as a low threshold value, exiting the calibration mode and updating the calibration threshold value after the calibration is finished, and replacing the original calibration value with the new calibration value by the earphone.
The embodiment provides a calibration method of a bluetooth headset, which includes determining a headset to be calibrated according to a headset calibration instruction when the headset calibration instruction is detected, acquiring infrared light values of the headset to be calibrated in a wearing state, and generating a first infrared light value set; acquiring each infrared light value of the headset to be calibrated in an unworn state as a second infrared light value set; and calculating and determining the calibrated infrared light threshold of the earphone to be calibrated based on a preset calculation rule, the first infrared light value set and the second infrared light value set, and finishing the updating of the infrared light threshold of the earphone. Through the mode, the method can calculate and determine the latest infrared light threshold value of the earphone to be calibrated based on the first infrared light value set of the earphone to be calibrated in a wearing state and the second infrared light value set of the earphone to be calibrated in an unworn state, so that the method for the user to calibrate the infrared light threshold value of the Bluetooth earphone by himself is provided, the measuring sensitivity of the infrared sensor of the Bluetooth earphone is improved, the wearing state identification accuracy of the Bluetooth earphone is improved, and the technical problem that the wearing state identification accuracy of the Bluetooth earphone based on the infrared sensor is reduced is solved.

step S31, determining each corresponding point of the first infrared light value set and the second infrared light value set, based on the collection time point of each infrared light value in the first infrared light value set and the collection time point of each infrared light value in the second infrared light value set;

And acquiring a calibration fixed value corresponding to the earphone to be calibrated, and calculating a difference value between the calibrated maximum infrared light threshold value and the calibration fixed value to be used as the calibrated minimum infrared light threshold value. Specifically, during the wearing of the right earphone, the values converted by the photodiode are collected every 20ms, and the invalid value smaller than 10 is filtered.
