MMDTS. Multifunctional mine data transmission system

The MMDTS multifunctional mine data transmission system is designed to provide switching and communication between mining equipment and measuring (including gas analysis, information and control systems), automated on-line dispatcher control (AODCSs), automated monitoring and control (AMCSs), communication, and personnel, transport and other equipment monitoring systems under normal operating conditions and with disconnected supply voltage.

Application: underground shafts, mines and associated surface structures, including gas and/or dust hazardous areas, as consistent with the explosion proof mark assigned to MMDTS components and required by the industry-specific safety regulations.

The MMDTS multifunctional mine data transmission system provides the possibility to implement different network topologies with the following capacities:

optical fiber/wired Ethernet: max. 10 Gbit/s;
IEEE 802.11 (Wi-Fi) b\g\n\ac\ax: max. 100 Мbit/s;
RS-485 field interfaces: max 2 Mbit/s, etc.

MMDTS flowchart

The MMDTS multifunctional mine data transmission system represents a block-modular project-oriented system.

MMDTS functions

transmission of data from interfacing systems to the server;
display of collected data on mimic diagrams of the mine dispatcher’s AWS;
archiving of collected data;
password protection against unauthorized access to System control and operating mode switching;
generation of reports based on specified criteria;
system operation without AC mains supply of both underground (based on battery backup) and surface (based on uninterruptible power supply sources) components;
diagnostics of system components, communication lines and power supply sources;
system expandability: introducing new technical devices without modifying system hardware while developing mine workings.

MMDTS includes network and internetwork equipment that is based on the following tech

cabling system-based: 10GBASE-X, 1000/100/10 Base-X (FX, TX), 1000BASE-T (max. 10 Gbit/s), RS-485 (max. 2 Мbit/s);
radio-based: IEEE 802.11 b\g\n\ac\ax (WiFi) (max. 100 Мbit/s).

Mobile voice communication can be implemented in deployed radio environment conditions based on the above radio technologies.

MMDTS can provide communication with the following SPBEC-MINING systems:

PTTCWS personnel and TMM tracking and collision warning system;
AFPS automatic fire protection system for underground mines;
MFVP.MH multifunctional highly explosion-proof mine video surveillance package;
ISTP informational software and temperature measurement package;
Voip communication;
other third-party systems/devices.
