The industrial 4G lTE router
emphasizes mostly on outdoor practicality, and its use scene is mainly industrial control projects, so it has high requirements for environmental adaptation, security protection, and appearance protection. 1. Industrial design of industrial 4G LTE router It adopts industrial 4G networking module and high-precision components to adapt to harsh outdoor environments such as high temperature and severe cold environment. It adopts the industrial high performance embedded structure in the industry and high performance industrial 32 bit ARM communication processor to ensure stable data transmission. The industrial installation buckle design is installed on the guide rail, and it can also be assembled at any time to install the ear. The sheet metal shell is adopted to increase the safety isolation coefficient. It is more suitable for site operation of industrial control project. 2. Security protection of industrial 4G LTE router It is built in electronic dog design, which ensures that the system is safe and stable, and never fails. The circuit protection includes the anti-reverse connection of power supply, ESD electrostatic protection and surge protection. The work is stable and reliable for 24 hours. The protection of the firewall can greatly improve the security of the internal network and reduce the risk.
