Detailed Description
The following examples are given for the detailed implementation and the specific operation procedures, but the scope of the present invention is not limited to the following examples.
Referring to fig. 1: a mine maintenance system based on leakage communication is characterized by comprising a signal/communication base station, a base station power supply, a leakage cable, a PLC control box, a two-way relay, a terminal load, a hand-held set and a locking button, wherein the signal/communication base station is connected with the base station power supply, the signal/communication base station is connected with the two-way relay through the leakage cable, the two-way relay is connected with the terminal load through the leakage cable, the signal/communication base station is connected with the PLC control box, the locking button is arranged in a control loop of the signal/communication base station and the PLC control box, the hand-held set is connected with the locking button control through a PLC controller, the mine maintenance system further comprises a loudspeaker, the loudspeaker is connected with the signal/communication base station through a loudspeaker interface, signals are transmitted through the leakage cable, and the stability of signal transmission is improved, and the locking button of the hand-held set provides safety guarantee for maintenance of maintainers, and accidents are prevented.
Referring to fig. 2: the PLC control box comprises a single-tank signal PLC and a double-tank signal PLC, the locking buttons are connected in parallel respectively and are connected with the single-tank signal PLC and the double-tank signal PLC respectively, and safety guarantee is provided for different overhaul parts respectively.
In a preferred embodiment of the present invention, the single tank signal PLC and the double tank signal PLC are provided on a single/double tank operation table.
As a preferred mode of the invention, the base station power supply can input AC127V/220V double voltage.
As a preferred mode of the present invention, the base station power supply can output +12V/+18V dual voltages.
In a preferred mode of the invention, the hand-held set is only arranged in the hand of the mine maintainer, so that the safety of the maintainer is further improved.
