In coal mining, it is crucial to have a power management system with high reliability, safety, and easy maintenance. The stability of the power supply not only affects worker safety but also impacts the effectiveness of coal production and the entire business. For example, harmful gases cannot be pumped out of the mine if the power system is out. In addition to being harmful to human health, such gases may also be flammable, creating a volatile environment where a single spark could set off a massive explosion.

In each pit, there are several power management systems scattered about to supply power and monitor the alarm system. Each power management system is protected inside an explosion proof case. If one of the devices short circuits and produces a spark, the case protects it from the volatile components in the atmosphere.

Moxa's UC-8418 RISC-based communication embedded computer is an ideal solution for monitoring and controlling power management systems. The UC-8418 features CAN and serial interfaces that can connect different protection devices. The DI/DO can also trigger the alarm system and send power supply data and monitoring data to the control center over the Ethernet LAN and fiber switch the second a protection device short circuits.
