System and method for monitoring faults of anti-explosion cable picking and laying machine under coal mine

Abstract

The invention discloses a system and a method for monitoring faults of anti-explosion cable picking and laying machine under a coal mine and belongs to systems and methods for cable picking and laying machines. The system comprises a first perception unit, a first signal processing unit, a second perception unit, a second signal processing unit and a control center, wherein the first perception unit and the first signal processing unit are arranged on a working machine; the second perception unit, the second signal processing unit and the control center are disposed on the anti-explosion cable picking and laying machine under the coal mine; the first perception unit comprises a flow transducer and a force transducer; the second perception unit is composed of an inner perception unit body and an outer perception unit body of the anti-explosion cable picking and laying machine under the coal mine; the first signal processing unit and the second signal processing unit comprise signal conditioning circuits, analog-to-digital conversion circuits, signal acquisition circuits, a first programmable logic controller (PLC) processor and a second PLC processor; the control center comprises a master control PLC processor, a man-machine interaction device, a sound-light alarm circuit, a data storage device and a cable winding device control system. The system has the advantages that the faults of the anti-explosion cable picking and laying machine are eliminated effectively, rapidly and reliably, and automatic control of the anti-explosion cable picking and laying machine under the coal mine is achieved.

Description

technical field [0001] The invention relates to a system and method of a cable retractable machine, in particular to a fault monitoring system and method of an explosion-proof cable retractable machine underground in a coal mine. Background technique [0002] When the walking machine works on the general excavation face of the coal mine, the cable retraction work is done manually, and there is no ready-made machine equipment. At present, the cable coiling equipment used in metal mines is mostly integrated on the working machine, and does not have explosion-proof characteristics. If the walking machinery in the coal mine is improved and the explosion-proof cable reel is integrated, not only the existing machine must be redesigned, which will bring a complicated workload, but also the existing mechanical equipment will become complicated and the volume will change. Big and inconvenient to use. In the patent document that the application number is 201020276705.3, "multifuncti...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a fault monitoring system and method for an explosion-proof cable retractor in a coal mine, which solves the problems of large cable retraction delay and excessive tension on the cable during the working process of the explosion-proof cable retractor in a coal mine. Complete the automatic control and real-time monitoring of the operating parameters and status of the explosion-proof cable retractor in the coal mine, and realize the automation, intelligence, visualization and humanization of the operation of the explosion-proof cable retractor in the coal mine
