Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0045] In response to the diversified requirements of the current car entertainment system, the car has begun to install antennas with various functions. Since the car antenna and the terminal on the vehicle mainly use Ethernet communication, and at the same time control the switching of antennas in different frequency bands, it is difficult to control them. And the problem of poor stability, the present invention provides a vehicle-mounted smart antenna system, which receives FM / AM signals, 3G / 4G signals and GPS / BeiDou signals through the GNSS antenna module, and the modulation of different signals is sent by the GNSS receiver according to the instruction requirements Demodulate the data to solve the problems of...

Abstract

The invention provides a vehicle mounted smart antenna system. The vehicle mounted smart antenna system comprises a GNSS antenna module, a GNSS receiver and a low noise amplifier module; the output end of the GNSS antenna module is connected with the input end of the low noise amplifier module; and the input end of the GNSS receiver is connected with the output end of the low noise amplifier module. The GNSS antenna module is used for receiving one or more of a FM / AM signal, a 3G / 4G signal and a GPS / Beidou signal and transmitting to the GNSS receiver as an antenna signal; the low noise amplifier module is used for amplifying the antenna signal of different frequency bands, so that the antenna signal can be demodulated and processed subsequently; and the GNSS receiver is used for modulatingand demodulating the received antenna signal to obtain a modulation and demodulation signal, and confirming to send the modulation and demodulation signals corresponding to one or more of the FM / AM signal, the 3G / 4G signal and the GPS / Beidou signal according to the instruction received by the CAN bus. The vehicle mounted smart antenna system can improve the smart control and user experience of the vehicle mounted antenna, and reduce the cost of equipment.

Description

technical field [0001] The invention relates to the technical field of automotive antenna communication, in particular to a vehicle-mounted smart antenna system. Background technique [0002] At present, the vehicle antenna technology is roughly divided into three types: radio antenna, 4G antenna and GPS antenna. With the development of electronic information and communication technology and the diversification of consumer demand, automobiles have begun to install antennas with various functions. For example, it not only receives conventional AM / FM radio signals, but also receives geolocation signals that help drivers confirm the location of a car and mobile communication signals used for in-vehicle information services. Since the existing positioning signal sources can be varied, the GNSS antenna can integrate multiple antennas to receive positioning or navigation signals. Among them, GNSS (Global Navigation Satellite System, Global Navigation Satellite System) refers to al...
