The ResBase is an intrinsically safe communication and coordination unit designed as a central element of the underground rescue operation system. It serves as the underground command post for the Rescue Operation Manager (ROM), enabling both wired communication with the surface and full situational awareness of the ongoing rescue mission.

By default, the ResBase operates as a standalone unit without built-in radio capabilities. However, once connected to an external BatNode, it gains full access to the wireless mesh network, enabling data transmission and real-time voice communication with the rescue teams in the field via mPhones. This modular approach ensures adaptability while maintaining explosion-proof safety standards.

The ResBase functions as the central monitoring hub of the rescue operation. It provides detailed insights into the entire system, allowing the ROM to supervise all connected devices within the network. The interface displays:

• a list of all active BatNodes and mPhones,

• signal strength and battery levels,

• assigned device numbers and operating channels,

• duration of immobility,

• proximity to the nearest device,

• and estimated location of each user based on signal triangulation.

This comprehensive overview allows the ROM to make rapid, informed decisions and enhances both the safety and efficiency of the rescue mission.

The ResBase is powered by an integrated rechargeable battery, offering up to 16 hours of autonomous operation. For extended missions, it can be recharged on-site using a dedicated ATEX-certified external battery pack. In non-hazardous zones where a standard 230V socket is available, the unit may also be powered externally without ATEX requirements.

Underground communication using mPhones can be simultaneously monitored by the ROM on the surface via the LISTENING/SILENCE switch. Communication between the ROM and ResBase is conducted via wire and is not broadcast to mPhones.
