Abstract

The invention relates to the technical field of water pump house remote control, and discloses a novel underground fluorite mine water pump house remote control device. The underground intelligent control module takes a Programmable Logic Controller (PLC) as a core and is communicated with the ground monitoring module through the data transmission module. The PLC receives signals such as water level and emergency stop of a water sump from the field signal acquisition module, outputs a control signal to the execution driving module after the internal preset water level linkage control logic operation so as to drive the start and stop of the mining drainage pump, and synchronously controls the state indicating module to display the system state. The device realizes remote centralized monitoring and full-automatic intelligent operation of the drainage system, and improves safety, reliability and operation economy.
