Problems solved by technology

However, in this solution, a digital processor is connected between the player demux unit and the Tuner unit, and the Tuner unit is controlled by the digital processor. Not only the hardware cost is high, but the data interface code is also more complicated, which is not conducive to the rapid processing of data.

Embodiment

[0047] Such as image 3 As shown, the technical solution of this embodiment includes an MPU, a first coordinator unit (indicated by tuner1 in the figure) and a second coordinator unit (indicated by tuner2 in the figure), and the first coordinator unit and the second coordinator unit The two coordinator units are directly connected to the MPU.

[0048] The MPU is used to store system software and is the main control unit of the system.

[0049] The first tuner unit is used to receive radio station signals and output audio.

[0050] The second tuner unit is used for background frequency band scanning and RDS signal reception. The software in the MPU achieves the functions of station search, RDS signal analysis and TMC signal analysis through the second tuner unit.

[0051] The second tuner unit includes a station search module, an RDS signal analysis module and a TMC signal analysis module;

[0052] The station search module is used to regularly scan all frequency points, an...

Abstract

The invention discloses a system and method for improving vehicle-mounted radio performance. The system comprises an MPU, a first turner unit and a second turner unit, wherein the first turner unit and the second turner unit are connected with the MPU. The MPU is used for storing system software and is a main control unit of the system, the first turner unit is used for receiving radio station signals and outputting audios, and the second tuner unit is used for background frequency band scanning and RDS signal receiving. Software in the MPU achieves the functions of radio station searching, RDS signal analysis and TMC signal analysis through the second tuner unit. According to the system for improving the vehicle-mounted radio performance, radio affairs are handled independently by adding a Turner chip, and the vehicle-mounted radio performance can be improved greatly. In addition, through the operation that the Turner chip is directly connected with the MPU, a digital processor is omitted, hardware cost is reduced, and meanwhile codes of digital interfaces are simplified.

Description

technical field [0001] The invention relates to the technical field of vehicle entertainment information, in particular to a system and method for improving vehicle radio performance. Background technique [0002] Such as figure 1 As shown, in the current vehicle system, there is only one Tuner (tuner) chip, which is used to handle radio affairs. In some application environments, two Tuner chips are required to receive signals separately to achieve the purpose. Such as better reception of RDS (radio digital signal) signal, real-time reception of TMC (radio traffic information broadcast) information, or uninterrupted channel search and so on. Such as figure 2 As shown, many chip companies have launched dual-tuner or multi-tuner solutions. Such as NXP's Dirana series, Silicon's multi-tuner solution. However, the above-mentioned solutions are usually expensive, and the DSP is used to coordinate and control multiple tuners in terms of architecture, and the interface codes ...
