Description

Technical field:

[0001] The invention relates to the technical field of Bluetooth headsets, and in particular to an automatic detection method for Bluetooth headsets. Background technology:

[0002] Bluetooth headsets use Bluetooth wireless connection technology, which eliminates the constraints of wired connections and greatly facilitates users. Current Bluetooth headsets include headsets and a charging box for charging the headsets. The working mode is as follows: When the headset is taken out of the charging box, the headset will be paired and connected to the corresponding playback device (such as a mobile phone) via Bluetooth. When the headset is placed in the charging box, the headset is disconnected from the playback device and starts charging. In order to ensure the quality of the headset, all Bluetooth headsets must be tested after production. One of the tests is to test the power on and off of the headset, and this project test is currently completed manually:

[0003] 1. After manually taking out the earphones from the charging box, manually determine whether the earphones will be paired and connected with the corresponding playback device, which takes about 10 seconds;

[0004] 2. Manually operate the playback device to play audio and manually determine whether the earphones sound normally, which takes about 60 seconds;

[0005] 3. Place the earphones in the charging box and manually determine whether the earphones are disconnected from the playback device, which takes about 10 seconds.

[0006] The above three steps constitute the headphone power on / off test. The headphone power on / off test requires stress testing, that is, the test needs to be repeated at least 100 times to detect possible low-probability problems.

[0007] As mentioned above, it takes at least 2 hours to complete the power-on and power-off stress test of a Bluetooth headset. Usually, power-on problems in Bluetooth headsets can only be discovered through multiple stress tests, so this test takes a lot of time.

[0008] In response to the above problems, I propose the following technical solutions. Summary of the invention:

[0009] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an automatic detection method for a Bluetooth headset, which can be completed automatically without manual operation, thus reducing the working time of personnel.

[0012] Furthermore, in the above technical solution, after completing a round of closed-loop testing, a waiting time is set, during which the charger charges the earphones.

[0013] Furthermore, in the above technical solution, the microphone is arranged in a sound pickup unit, and the sound pickup unit includes a microprocessor and a microphone. The sound pickup unit is integrated in a computer or is an independent unit connected to the computer.

[0014] Furthermore, in the above technical solution, the smart terminal is: a smart phone or a tablet computer.

[0015] After adopting the above technical solution, the Bluetooth headset is automatically tested using a computer and a smart terminal to detect the power on and off test and the normal sound test of the Bluetooth headset.

After going to work the next day, the test data can be obtained, which can save a lot of test time and improve test efficiency. Specific implementation method:

[0016] The present invention is further described below in conjunction with specific embodiments.

[0017] The present invention is a method for turning on and off a Bluetooth headset and detecting sound. The so-called turning on and off and detecting sound mainly refer to: when the headset is taken out of the charging box, the headset will be paired and connected with the corresponding playback device (such as a mobile phone) via Bluetooth. When the headset is placed in the charging box, the headset is disconnected from the playback device and charging begins. In addition, when the headset is connected to the corresponding playback device, the headset can normally play the audio generated by the playback device.

[0018] Therefore, the Bluetooth headset of the present invention comprises: a headset and a charger matched with the headset, and the charger is generally a charging box. During the implementation of the present invention, the Bluetooth headset, computer and smart terminal to be tested need to be connected in sequence to form a closed-loop test system.

[0019] The computer can be a personal computer terminal, which can be integrated with a sound pickup unit, or can be connected to an external sound pickup unit. If the external sound pickup unit is connected, the external sound pickup unit should include: a microprocessor and a microphone, and the sound pickup unit is integrated in the computer or connected to the computer as an independent unit. The sound pickup unit is mainly used to collect the audio signal played by the Bluetooth headset, and convert it into digital information, and transmit it to the computer processing unit, so as to determine whether the headset makes sound normally.

[0020] The intelligent terminal may be any mobile intelligent device such as a smart phone, a tablet computer, or a smart player.

[0021] When testing the present invention, the headset is first connected to the charger, which includes the following steps:

[0022] Step 1: Set the test parameters on the computer, such as the test duration, the number of loop tests, the time interval between loop tests, etc.

[0023] Step 2: Control the charger on and off through the computer, so as to control whether the charger outputs the charging current. For the external pickup unit, the charger can be directly controlled by the microprocessor in the pickup unit.

[0024] Step 3: The headset is connected to the smart terminal via Bluetooth. After the connection is established, the smart terminal collects the headset's return data.

[0025] Step 4: Connect the smart terminal to the computer and transmit the collected headphone data to the computer. The computer performs statistical analysis on the data. The smart terminal and the computer can be directly connected and output via a USB data cable.

[0026] Step 5: The smart terminal starts playing audio, and the audio is transmitted to the headset via Bluetooth connection and played through the headset;

[0027] Step 6: The headset continues to play audio, which is collected by the microphone and then transmitted back to the computer;

[0028] Step 7: The computer records the collected audio data and determines whether the sound of the earphone is normal, thus completing a round of closed-loop testing;

[0029] After completing a round of closed-loop testing, set a waiting time during which the charger charges the headset. Repeat the above test until the set test time or number of cycles is reached.

[0030] The specific testing process of the present invention is as follows.

[0031] 1) Conduct environmental testing of the entire test system and detect the connection status of computers, smart terminals, and Bluetooth headsets.

[0032] 2) Out-of-box command, i.e., sending a command through the computer, the pickup unit shuts down the charger, disconnecting the earphones from the charger, thereby simulating the scene of taking the earphones out of the charger;

[0033] 3) Start the connection test to detect whether the headset is paired and connected to the smart terminal through Bluetooth after being disconnected from the charger. Within the set time, the smart terminal will collect the headset's back-connection data, which includes any combination of Acl (access control list), HFP (hands-free function), AVRCP (audio remote control protocol), A2DP (Bluetooth audio transmission protocol), SCO (transmission-oriented for voice transmission), SPP (serial port configuration protocol), BLE (Bluetooth and other energy-consuming technologies) data. First, check whether Acl is connected, and then check whether HFP, AVRCP, A2DP and other back-connection data are connected. If the smart terminal collects the above data within the set time range, it means that the connection is completed and the connection is normal. If any data is not collected within the set time, it means that the connection is abnormal. If only A2DP is not connected, skip the subsequent audio test.

[0034] 4. After the startup connection test is normal, the audio test will be carried out. First, the computer sends a command to control the smart terminal to start playing the set audio. The audio played by the smart terminal will be transmitted to the headset via Bluetooth transmission, and the headset will start to make sound. At this time, the microphone in the sound pickup unit collects the sound played by the headset and converts the sound into a digital signal and transmits it to the computer. Within the set time range, the computer will judge whether the headset makes sound and whether the sound is normal through the returned audio signal.

[0035] 5. After the audio test is completed, the following test will be conducted: the computer will issue a command, and the pickup unit will turn on the charger, so that the earphones can be connected to the charger, thereby simulating the scene of the earphones being placed in the charger. In normal use, when the earphones are placed in the charger, the charger starts charging the earphones. At this time, the earphones should disconnect the Bluetooth connection with the smart terminal and enter the charging mode.

[0036] 6) Start the connection test again to detect whether the headset disconnects the Bluetooth connection with the smart terminal after connecting to the charger. Within the set time, the smart terminal will collect the headset's reconnection data, which includes: whether A2DP has been disconnected, whether AVRCP has been disconnected, whether HFP has been disconnected, whether Acl has been disconnected. If the smart terminal collects the above connections within the set time range, it means that the headset has been disconnected from the smart terminal normally. Otherwise, it means abnormal.

[0037] 7) Enter the waiting time, during which the charger charges the headset to ensure that the battery of the headset will not be exhausted during the entire test process and can continue to work.

[0038] 8) The above test is repeated continuously until the set test time or number of cycles is reached.

[0039] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
