5G or 4G multi-band wireless broadband portable terminal

Abstract

The invention discloses a 5G or 4G multi-band wireless broadband portable terminal which comprises a shell. A reserved hole site and a power switch are arranged on one side of the outer portion of the shell, and an RS458 interface, a CAN interface, a wifi antenna interface, a 5g antenna interface, a GPS interface and a 232 interface are arranged on the other side of the outer portion of the shell. An explosion-proof inner shell, a mining rechargeable battery, an intelligent charging control panel, a power supply module and a mining intrinsic safety type terminal function mainboard are arranged in the outer shell, and the terminal is small in size, light in weight and convenient to carry and deploy; the system can conveniently adopt a CAN interface, an RS485 interface, an Ethernet interface, WIFI and other modes to provide a 5G or 4G wireless access mode for various types of underground coal intelligent equipment, the explosion-proof and explosion-proof requirements of the underground coal mine can be met, meanwhile, a built-in battery is arranged in the equipment, when an external mining power supply fails, the internal battery is automatically switched to supply power to the equipment, the communication continuity is guaranteed, and the safety of coal mine production is improved.

Description

technical field [0001] The invention belongs to the technical field of mine-used intrinsically safe terminals, and in particular relates to a 5G or 4G multi-band wireless broadband portable terminal. Background technique [0002] At present, my country has achieved continuous 5G network coverage in urban areas and some counties and cities across the country. With the further advancement of the country's new infrastructure facilities based on 5G networks, the coverage of 5G networks will also become better and better. As a result, 5G has been applied in the fields of factories, agriculture, sports and entertainment, medical care, transportation, finance, tourism, education, and electric power. Smart terminals in vertical industries cannot be completely 5G, and a large number of powerful 5G data transmission terminals are required. , to provide terminals in the industry with the ability to access 5G networks, thereby promoting the application of 5G in vertical industries. [...

AI Technical Summary

Problems solved by technology

[0003] Due to the complex wireless transmission environment in mines and the presence of flammable and explosive gases such as gas, the existing 5G terminals have poor environmental adaptability and do not have explosion-proof features, which cannot meet the safety production requirements of coal mines. At the same time, the existing 5G portable terminals use The external mining power supply supplies power to the equipment. When the external mining power supply fails, the 5G portable terminal will not be able to continue to work due to the lack of power supply, which will interrupt the communication.
