Problems solved by technology

[0002] The hydraulic support electro-hydraulic control system can realize the control of a single group of hydraulic supports by configuring a variety of sensors, multiple solenoid valve drivers and corresponding electromagnetic pilot valves. However, when multiple hydraulic supports in a single group operate at the same time, multiple The solenoid valve drivers work at the same time, which will instantly increase the peak current and power consumption of the power supply, which will not only threaten the safety performance of the power supply, but also shorten the power supply time and service life of the power supply

Abstract

The invention discloses a hydraulic support and an electro-hydraulic control system thereof. The system comprises a monitoring host, a power module, a controller and an electromagnetic valve driver. The power module is used for providing electric energy for the system, monitoring power utilization information of all loads in the system and sending the power utilization information to the monitoring host. The monitoring host is used for generating and issuing a corresponding first control instruction to the power module when the power utilization information provided by the power module contains current overload information so that the power module can control currents of the corresponding loads, and generating and issuing corresponding decision control instructions to the controller and the electromagnetic valve driver according to state information provided by the controller and / or the electromagnetic valve driver. The controller and the electromagnetic valve driver are both used for executing corresponding energy-saving measures according to the received corresponding decision control instructions. Thus, the system can improve the safety performance of a power source, shorten the power supply time of the power source and prolong the service life of a battery.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a hydraulic support and an electro-hydraulic control system thereof. Background technique [0002] The hydraulic support electro-hydraulic control system can realize the control of a single group of hydraulic supports by configuring a variety of sensors, multiple solenoid valve drivers and corresponding electromagnetic pilot valves. However, when multiple hydraulic supports in a single group operate at the same time, multiple The solenoid valve drivers work at the same time, which will instantly increase the peak current and power consumption of the power supply, which will not only threaten the safety performance of the power supply, but also shorten the power supply time and service life of the power supply. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art to a certain extent. [0004] Therefor...
