Problems solved by technology
However, since most of the current mobile carriers use a single antenna for communication, when the mobile satellite antenna is blocked by a tall object, the satellite network link will be interrupted and the Internet cannot be accessed.
[0003] In order to reduce the probability of the satellite antenna being blocked and make the satellite link more stable, some mobile carriers use a dual-antenna system, but the existing dual-antenna system generally uses two independent antenna control units and a third-party intelligent gateway. The hardware equipment is cumbersome and the layout is complicated
Although two satellite antennas are used for communication, it is still a single-antenna control method, that is, network load balancing or active-standby network switching is performed according to whether there is a satellite network. This does not make the most efficient use of dual-antenna resources, so There are disadvantages of non-optimal network link selection. For example, the signal quality of one set of satellite antennas is poor compared to the signal quality of another set of satellite antennas, but online, if the antenna with poor signal quality is set as the main antenna , it will cause the quality of the network signal used by the mobile carrier to be relatively poor, affecting the user experience

A dual-antenna system is characterized in that a second satellite antenna and a second satellite cat are arranged on the mobile carrier, the antenna control unit includes a power supply, a communication control module and a POE power supply unit, and the communication control module includes a WAN interface, a 4G communication module, and a hard disk storage. , LAN interface, main CPU, auxiliary CPU, load balancing module, WiFi chip and external interface, the power supply is electrically connected to the communication control module, the LAN interface is electrically connected to the POE power supply unit, and the outer casing of the antenna control unit is provided with a 4G antenna. The balancing module is controlled by the main CPU, and the load balancing module can connect multiple network segments using different protocols. The advantage is that two sets of satellite antennas are arranged on the mobile carrier. When the signal of one set of satellite antennas is blocked, the other set of satellite antennas It can ensure normal communication, and at the same time cooperate with the load balancing module in the antenna control unit to ensure that the network communication selects the network link with the best quality in real time.
Description
technical field [0001] The invention relates to a mobile satellite antenna, in particular to a dual-antenna system and a selection method thereof. Background technique [0002] As more and more mobile carriers use VSAT as a means of daily communication and data return, the stability and reliability of the satellite network has always been the first point of concern for users. However, since most of the current mobile carriers use a single antenna for communication, when the mobile satellite antenna is blocked by a tall object, the satellite network link will be interrupted and the Internet cannot be accessed. [0003] In order to reduce the probability of the satellite antenna being blocked and make the satellite link more stable, some mobile carriers use a dual-antenna system, but the existing dual-antenna system generally uses two independent antenna control units and a third-party intelligent gateway. The hardware equipment is cumbersome and the layout is complicated. A...
