A vehicle-mounted multi-network and multi-frequency fusion broadband mobile communication device

Abstract

The invention discloses a vehicle-mounted multi-network and multi-frequency fusion broadband mobile communication device. The equipment includes aggregation transmission unit, formation communication unit, edge computing unit, control switching unit, command telephone unit, Beidou communication unit, switching backplane, power backplane and external DC power supply. Among them, the aggregation transmission unit is used to provide data aggregation transmission supporting multiple mobile communication standards; the formation communication unit is used to provide ad hoc broadband mobile data transmission between the device itself and other devices in the formation; the edge computing unit is used for computing Determining the data transmission mode; controlling the switching unit, configured to implement link switching between the aggregation transmission unit and the formation communication unit according to the data transmission mode determined by the edge computing unit. The invention supports the integration of multiple communication modes and network intelligent switching, and can improve the adaptability of equipment to the communication environment.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted mobile communication equipment, and more particularly, relates to a vehicle-mounted multi-network and multi-frequency fusion broadband mobile communication device. Background technique [0002] At present, various industries have a very strong demand for mobile command in temporary emergency response, dispatch, and inspection. At the same time, the mobile command has gradually extended from the voice command in the early stage to the visual graphic command. In large-scale operations, this will place high requirements on the transmission bandwidth of the field and the command center. [0003] At present, long-distance broadband wireless transmission is basically implemented based on public wireless network backhaul or satellite backhaul, in which satellite communication is limited by resources, with high usage costs and low communication bandwidth; for public wireless networks, each operati...

Problems solved by technology

[0003] At present, long-distance broadband wireless transmission is basically implemented based on public wireless network backhaul or satellite backhaul, in which satellite communication is limited by resources, the cost of use is high and the communication bandwidth is low; for public wireless networks, each operator Carriers have achieved 3G / 4G network coverage of 90% of the domestic area, but the coverage effect of each carrier is uneven, and it is difficult to meet the long-distance and continuous data upload requirements through a single carrier; communication between vehicle formations in large-scale operations is currently difficult. Only narrow-band voice communication has been popularized, and there is no means of broadband communication; at the same time, in order to meet the external communication needs of vehicle formations, it is often necessary to install a variety of communication equipment and transform the vehicle power distribution system, which is a great waste of time. Resources, and caused the phenomenon of dedicated vehicles, resulting in extremely inflexible vehicle configuration when performing tasks, and increased fault nodes
