Cloud Terminal
BGK-GN2 cloud terminal is a new-generation, low-power engineering safety monitoring device developed based on NB-IoT wireless communication technology.It is widely used for automated geotechnical safety monitoring in various environments such as geological disasters, hydropower stations, reservoirs, highways, bridges, slopes, and subways.
BGK-GN2 cloud terminal is a new-generation, low-power engineering safety monitoring device developed based on NB-IoT wireless communication technology. It can access to various types of sensors including vibrating wire, potentiometer, standard analog, and digital sensors. It features ultra-low power design, with power consumption less than 0.3 mW in sleep mode and less than 50 mW in always-on mode. It supports automatic time synchronization. Built-in Bluetooth enables configuration and data acquisition. It supports NB-IoT/RS485 networking, remote control, and seamless integration with the cloud platform via its built-in communication module for plug-and-play operation.
The enclosure is fully sealed, with a built-in solar panel and rechargeable lithium battery. It achieves IP67 protection rating, is compact in size, and easy to install, making it suitable for all-weather operation in various harsh environments. It is particularly suitable for off-grid environments with sunlight exposure. It is widely used for automated geotechnical safety monitoring in various environments such as geological disasters, hydropower stations, reservoirs, highways, bridges, slopes, and subways.
