Korenix JetBox series compact Embedded Linux Computers have been integrated in front-end controller systems in underground mining sites to ensure their real-time remote control and monitoring. Through versatile interfaces, including LAN, Serial, DIO and USB ports and the VPN routing functionality, they perform multi-tasks by providing device and signal control and simultaneously securing the network infrastructure in an economical budget. Moreover, to withstand the unfavorable environmental conditions, the RISC-based computers with low power consumption provide rugged design and -40~80℃ wide operating temperature and therefore ensure the reliable data management under harsh environmental conditions, becoming the perfect solutions for programmable front-end control applications in mines.

Mining operations are deployed with sophisticated industrial controls and sensors for safety and operations efficiency. These sites must work around the clock to be operationally efficient and productive and must experience minimal downtime due to communication failures. With the severe environmental conditions underground, the networking of mining areas requires rugged, anti-vibration specifications of devices to ensure complete control of loading operations while securely transferring data.

To meet all these requirements, Korenix Industrial Embedded Front-end Linux computers have been chosen by the coal mine drilling company to integrate in the networking infrastructure for remotely monitoring engineering data, providing real-time device and process control and connecting to personnel tracking throughout the mines.
To connect and remotely manage PLCs, gas flow meters, thermal detectors and other environment-controlling devices in the underground mining sites, Korenix JetBox 5432-w embedded VPN routing computers have been used, capable of providing high quality data transfer through serial ports. For ensuring digital connectivity of sensors, alarms and other devices, JetBox 3300-w series with integrated DIO interface further completed the network infrastructure. With their small size, they have been easily integrated in small front-end control systems. |

By collecting all the information in the system, the JetBox 5432 series using their complete Layer3 routing and VPN functionalities, operated as networking gateways to securely expend networking capabilities to the control center through wireless dongle or through LAN, and therefore, allowing administrators to manage the systems remotely from the control centers. The built-in Linux OS of the computers further provided easy network maintenance and fast remote access for the administrators. Besides, using the Linux SDK functionality, they were able to develop their own programmable front-end controller applications.
By supporting wide operating temperature range and rugged design with resistance to shock and vibration, they performed reliably in harshest conditions of underground sites becoming the best solutions for real-time mining area control.
