Broadcasting-station searching method, broadcasting-station searching device and vehicular infotainment system

Abstract

The invention relates to a broadcasting-station searching method, a broadcasting-station searching device and a vehicular infotainment system, wherein the broadcasting-station searching method comprises the following steps of: preliminarily establishing a storage unit for loading a broadcasting-station information database at a local terminal, and setting a broadcasting-station searching condition through a human-computer interaction interface of the local terminal; and searching out related broadcasting-station information sets meeting the searching condition according to the searching condition through a control unit arranged at the local terminal, and then displaying on the human-computer interaction interface. According to the invention, the finish of condition input and condition searching at the local terminal is realized by arranging a searching process at the local terminal, so that the searching efficiency is improved, and defects caused by a remote database-establishing scheme in the prior art are avoided; in addition, the high efficiency of the searching process is realized by adopting a preferred scheme of double-laying searching at a minimum rectangle beyond the range of a broadcasting station and the coverage area of broadcasting-station signals; and when the broadcasting-station searching device is applied to the vehicular infotainment system, because each hardware of the broadcasting-station searching device can be directly loaded or existing hardware equipment of the vehicular infotainment system per se is utilized, the utilization ratio of resources is optimized.

Description

technical field [0001] The invention relates to a station search technology, in particular to a station search method, a station search device and a vehicle-mounted infotainment system. Background technique [0002] Radio is a platform for people to entertain and obtain information. At present, radio is widely used, and it is also widely used in the field of vehicles and mobile terminals. With the advancement of science and technology, the performance of the radio has been greatly improved, the number of radio stations has continued to increase, and the content of radio stations has become increasingly rich. [0003] Chinese invention patent application (application number 200810093939.1, application date is April 23, 2008) proposes a method for radio station search in wireless terminals, which aims at the existing radio station automatic search technology, due to the interference of the external environment, It is difficult to search all local radio programs and is limited...

AI Technical Summary

Problems solved by technology

[0007] At the same time, the radio station information in the existing technical solution is all built in the remote server, and its information exchange reliability, search efficiency, and the defects of large server load and high cost are urgent no matter whether it is used to search for traditional radio stations or RDS radio stations. To be improved

[0008] At the same time, the advancement of technology and diversified lifestyles have made the frequency of radio use more in the vehicle infotainment system, which determines that the radio technology is mainly based on the vehicle platform for research and development. Compared with mobile terminals or Stand-alone radio, which has the characteristics of strong mobility, further reduces the effectiveness of communication between the local end and the remote server (for example, the car is in a remote area or in a tunnel); at the same time, the time and frequency for the user to operate the device while the vehicle is driving The limitations are relatively large, which requires the station search system to meet the characteristics of fast and convenient search and selection. In this regard, the existing technology still needs to be improved
