The invention provides an automobile audio playing control method based on Bluetooth and DLNA technology fusion. The method comprises the following steps that S1, an automobile cabin is connected with a mobile phone WIFI hotspot, and a mobile phone is connected with automobile cabin Bluetooth; s2, the automobile cabin detects a WIFI connection state and starts a DLNA connection monitoring service; s3, the mobile phone terminal transmits data to a vehicle cabin by using a DLNA protocol; s4, the automobile cabin displays a DLNA music interface and plays tracks; s5, the DLNA music interface controls the mobile phone end to play and stop through a Bluetooth protocol; and S6, the WIFI connection is disconnected, and a DLNA music interface is hidden in the automobile cabin. Under the conditions that a DLNA protocol is realized at an automobile cabin end and the automobile cabin end is connected with a mobile phone end through a WIFI network, audio data of a mobile phone is transmitted to an automobile cabin, transmission of lossless data is realized by utilizing the DLNA, a standard communication interface between a mobile phone music APP and an automobile is opened, and the transmission problem of high-quality music is well solved. In addition, by combining a Bluetooth control protocol, the control of playing up and down and pausing of music tracks is realized.
Description
technical field [0001] The invention relates to the field of vehicle audio control, in particular to a vehicle audio playback control method based on the fusion of Bluetooth and DLNA technologies. Background technique [0002] DLNA was first proposed by Sony, Intel, Microsoft, etc., and its full name is DIGITAL LIVING NETWORKALLIANCE. It aims to solve the interconnection between wireless and wired networks including personal PCs, consumer appliances, and mobile TVs share a variety of digital media and content services such as photos, video, audio, and more. The Bluetooth control protocol AVRCP defines the characteristics of how to control streaming media. This includes pausing, stopping, starting playback, volume control, and other types of remote control operations. AVRCP defines two roles, the controller and the target device. The controller is usually the remote control device, and the target device is the device whose characteristics can be changed. The current popul...
