Mining hydraulic support monitoring system and mining hydraulic support monitoring method

Abstract

The invention discloses a mining hydraulic support monitoring system, comprising a master controller, a power supply, a mining hydraulic monitoring unit, a communication circuit and a mining hydraulic drive monitoring unit. A mining hydraulic support monitoring method comprises the following specific steps of: a) executing module initialization; 2) checking whether a control instruction from the mining hydraulic monitoring unit exists; 3) judging whether to transmit the latest fault information to the hydraulic support monitoring unit in real time; 4) judging whether to perform lifting drive control for a solenoid valve of the Nth mining hydraulic support; and 5) judging whether to perform descending drive control for the solenoid valve of the Nth mining hydraulic support. According to the system and the method, the mining hydraulic monitoring unit and the mining hydraulic drive monitoring unit are separately arranged, maintenance can be performed without executing total shutdown, the maintenance modes are more flexible, and the work efficiency during maintenance is improved. By monitoring the mining hydraulic support, the safety is enhanced, and the fault locations are indicated for the workers, so that the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to a monitoring system and method of a hydraulic support, in particular to a monitoring system and method of an underground hydraulic support. Background technique [0002] The electric control hydraulic system of mine hydraulic support is a pilot-operated electro-hydraulic switch control system, which outputs a combined control signal through the controller, and the corresponding hydraulic jack is controlled by the electro-hydraulic control reversing valve to perform corresponding actions. At present, the electronically controlled hydraulic system of domestic mining hydraulic support generally adopts the control method that all control circuits are installed in one control unit, so that once the input and output of the electronically controlled hydraulic monitoring unit of mining hydraulic support are set, they cannot be changed, and cannot be changed according to specific conditions. Configuration; once a problem occurs during t...

Problems solved by technology

At present, the electronically controlled hydraulic system of domestic mining hydraulic support generally adopts the control method that all control circuits are installed in one control unit, so that once the input and output of the electronically controlled hydraulic monitoring unit of mining hydraulic support are set, they cannot be changed, and cannot be changed according to specific conditions. Configuration; once a problem occurs during the use of the equipment, it needs to be shut down for maintenance and replacement, which brings some inconvenience to both production and use, and reduces the flexibility of the equipment.
