specific Embodiment approach 1

[0049] In practical applications, considering that the problem of signal mutual interference between antennas with similar signal frequency bands is more prominent, in the embodiment of this specification, spaced deployment can be used between antennas with similar signal frequency bands. Specifically, it can include: using Antennas with similar signal frequency bands on the circuit board are deployed in such a manner that the distance between antennas with similar signal frequency bands on the circuit board is not less than a preset distance threshold. Wherein, the preset distance threshold may be determined based on an experimentally obtained correspondence between the degree of mutual interference between signals and the distance between antennas. For example, assuming that the tolerable degree of mutual interference between signals is generated when the distance between antennas is not less than d, then d may be used as the distance threshold.

[0050] It can be understood...

specific Embodiment approach 2

[0059] In practical applications, although the distance between antennas with similar signal frequency bands in the above method 1 is not less than the preset distance threshold, the problem of signal mutual interference can be avoided to a certain extent, but the antenna can be deployed on the circuit board. In the case of limited space, signal mutual interference problems may also occur between physically adjacent antennas, for example, figure 2 The medium ETC signal transmitting and receiving antenna and the mobile communication signal transmitting and receiving antenna may be physically adjacent antennas.

[0060] On the basis of the first method above, in order to further avoid the problem of signal interference, in one or more embodiments of this specification, the antennas disposed adjacently on the circuit board are respectively provided with different antenna polarization modes.

[0061] In one embodiment, the antennas disposed adjacently on the circuit board are res...

specific Embodiment approach 3

[0065] On the basis of adopting the above method 1 or method 2, a wave-absorbing material of a preset frequency band may also be provided on the adjacent side of each antenna among the plurality of antennas. Wherein, the adjacent side here may include upper side, lower side, left side and right side. It can be understood that the installation position of the absorbing material can be set according to the actual situation, for example, figure 2 A setting method of the absorbing material shown in , the absorbing material can be set on the lower side and the left side of the ETC signal transmitting and receiving antenna. It can be understood that since there is no adjacent antenna on the upper and right sides of the ETC signal transmitting and receiving antenna , in order to save cost, there is no need to set up the absorbing material.

[0066] In practical applications, the preset frequency band is the working frequency band of the antennas deployed adjacent to each antenna. ...

Abstract

The invention discloses a vehicle-mounted terminal system which comprises a wireless signal transceiving module which is arranged in a shark fin on a vehicle roof and comprises a plurality of antennas; a processing control module which is arranged in the vehicle roof, is positioned on the lower side of the wireless signal transceiving module and is connected with the wireless signal transceiving module through a Wilkinson power divider; and an in-car entertainment which is arranged on a center console in the vehicle and is connected with the processing control module through an optical fiber.According to the invention, the problems of high development cost, high development difficulty and difficulty in period control of the conventional intelligent networked automobile can be solved.

Description

technical field [0001] The present application relates to the field of vehicle technology, in particular to a vehicle terminal system. Background technique [0002] Intelligent networked vehicles have become a global development trend, and my country is in a critical period of transformation from a major automobile country to a powerful automobile country. Among them, the development of intelligent networked vehicles will play an extremely important role in the development and rise of my country's automobiles. The R&D, design, application and popularization of vehicle-mounted terminals, which are key components of intelligent connected vehicles, will directly affect the development and future of my country's automobile industry in the new era. [0003] At present, there are many types of vehicle-mounted terminals. A car needs to be equipped with many terminal subsystems, such as: antenna system, Internet of Vehicles system, Electronic Toll Collection (ETC) system, vehicle-ma...
