A modular controlling system for controlling and/or interfacing sophisticated power, communication, monitoring, lighting, ventilation and/or other services systems in complex environments such as underground mines, pharmaceutical laboratories and production facilities and nuclear plants comprises a main processing unit, several communication interface units, several equipment interface units, and a user interface unit. The modular controlling system is configured to be installed in a complex environment such as an underground mine and connected to various mining equipment, including ventilation equipment and environmental sensors. The modular controlling system is generally preprogrammed and preconfigured with all the necessary operating programs, control algorithms and equipment drivers such as to required minimal customization upon installation.

Provided are a method and apparatus for remote coal mine leakage test. The remote leakage test method comprising: installing and connecting a leakage test device (3) at the a control switch (2) located at the most distal end of a coal mine power line (5); a leakage detection and protection device (1) connecting the leakage test device (3) via the coal mine power line (5) and providing it with a detection circuit for detecting whether remote leakage has occurred; generating a grounding current flowing through the coal mine power line (5) by controlling the grounding of the leakage test device (3); the leakage detection and protection device (1) detecting the grounding current, and enabling a leakage protection relay (KA) to operate, so as to cut off the coal mine power line (5); and detecting the coal mine power line (5) or manually observing an indication lamp (HL), so as to determine whether the remote leakage test is successful. The coal mine remote leakage test device and method are safe, convenient and time-saving.
