Abstract

The invention discloses a multi-antenna combining device and system. The multi-antenna combining device comprises at least two antennas, an antenna switching module and at least two combiners, the antenna switching module comprises at least two detection ends, at least two first connecting ends and at least two second connecting ends, the at least two detection ends are electrically connected with the at least two antennas in a one-to-one correspondence mode, the at least two first connecting ends are electrically connected with the at least two antennas in a one-to-one correspondence mode, and the at least two second connecting ends are electrically connected with the at least two antennas in a one-to-one correspondence mode. The at least two second connecting ends are in one-to-one correspondence with the at least two first connecting ends, and each second connecting end is electrically connected with the combining end of the combiner; and the antenna switching module is used for detecting preset parameter information of the corresponding antenna through the detection end and determining a conduction state between the first connection end and the second connection end according to the preset parameter information. According to the invention, the antenna which works normally can be automatically selected, the antenna redundancy function is realized, and the communication stability is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular, to a multi-antenna combining device and system. Background technique [0002] With the rapid development of communication technology, there are more and more communication devices. In order to ensure data transmission, the types and numbers of antennas are also increasing. This leads to limited space for antenna installation in relatively narrow environments such as trains. , it is easy to cause the distance between the antennas to be too close, so that there is a problem of mutual interference in signal reception and processing, and the communication quality is reduced. At present, the number of antennas is mainly reduced as much as possible through the combiner, so as to improve the communication environment. [0003] The existing multi-antenna combiner can integrate multiple antennas, but the antenna may fail during use, and cannot be...
