Test terminal and method for portable car audio and radio based on wireless communication

Abstract

The invention relates to a portable vehicle-mounted audio and radio test terminal and method based on wireless communication. The test terminal is a hand-held debugging terminal used for bearing tuning APP software. The tuning APP software comprises an audio test module and a radio test module. The audio test module and the radio test module are connected with the vehicle-mounted information entertainment host through a wireless communication module arranged in the handheld debugging terminal. The audio test module can debug the performance parameters of Audio in the vehicle-mounted infotainment host, and the radio test module can debug the performance parameters of Radio in the vehicle-mounted infotainment host. The handheld debugging terminal is responsible for debugging Audio or Radio performance parameters and transmitting a control instruction to the vehicle-mounted information entertainment host by means of Bluetooth wireless communication, and the vehicle-mounted information entertainment host makes a specific action response to achieve the optimal sound effect or radio effect.

Description

technical field [0001] The invention relates to the technical field of vehicle audio equipment testing, in particular to a wireless communication-based portable vehicle audio and radio testing terminal and method. Background technique [0002] At present, the road test system is mainly used to test the on-board audio equipment in the car, that is, the whole system involved when the debugger calibrates the sound effect index of the audio (Audio) and the performance index of the radio (Radio) in the real car environment. , so that users can experience a series of operations such as the best sound effects and radio effects on the real car. [0003] The existing road test system needs to be connected with many peripheral devices such as laptops, bus monitoring devices, and serial port tools, and control the functions of Audio or Radio by triggering the bus monitoring device to send signals or input a series of complex commands from the serial port. Entering commands is very com...

AI Technical Summary

Problems solved by technology

Therefore, the existing road test system has many shortcomings such as heavy equipment, messy and unstable connections, complicated and difficult to understand controls, etc., and because debuggers need to carry a large number of peripheral devices and wiring harnesses, and need to learn cumbersome debugging procedures, resulting in road test failures. longer period
