Problems solved by technology
The traditional way of testing the anti-jamming performance of Bluetooth headsets is mainly to choose scenes with more interference signals, such as airports, high-speed rail stations, etc., and judge the sound quality of Bluetooth headsets through human listening. However, the amount of interference signals in these scenarios is It changes at any time and fluctuates greatly, and the battery power of the device will also affect the Bluetooth connection, and the standard of judgment cannot be unified by the way of human listening, so the quantitative analysis of the Bluetooth headset anti-interference test cannot be done. The test results refer to It is not meaningful

The invention relates to a method for evaluating the anti-interference performance of a Bluetooth headset by quantizing a simulated interference environment. The method comprises the following steps: establishing a quantized Bluetooth simulated interference environment; placing a to-be-tested Bluetooth earphone and a first Bluetooth pairing device in a Bluetooth simulation interference environment, establishing a connection, and transmitting data information to the to-be-tested Bluetooth earphone through the first Bluetooth pairing device; sound signals sent by the to-be-tested Bluetooth earphone in a time period are continuously sampled, and sampled audio signals are obtained; and comparing the sampled audio signal with a pre-selected standard audio signal, judging whether the connection between the to-be-tested Bluetooth earphone and the first Bluetooth pairing equipment is interrupted or not, and counting interruption information. In the invention, the interference signal can be quantified, and the standard for judging the connection interruption of the Bluetooth earphone to be tested can be quantified, so that the problem that the test result loses reference significance due to the fact that the interference environment changes in the test process and the judgment standards are not uniform when the connection state is judged manually is solved.
Description
technical field [0001] The invention belongs to the technical field of anti-interference performance testing of bluetooth earphones, and particularly relates to a method for evaluating the anti-interference performance of bluetooth earphones by quantifying and simulating interference environment. Background technique [0002] Since the 2.4GHz ISM frequency band does not require a license and is open to the world, there are many users due to its convenience. For example, mobile phones, WIFI, Bluetooth, IoT, microwave ovens, etc. are all in this frequency band. When the signal is crowded, it will lead to the connection of Bluetooth headsets. Interruption, thereby bringing a bad user experience to the user. Due to the existence of interference, there is a need to test the anti-interference ability of Bluetooth headsets. The traditional way to test the anti-interference performance of Bluetooth headsets is mainly to select scenes with more interference signals, such as airports...
