A Mine Electromagnetic Valve Control System with Intelligent Power Supply Switch

Abstract

The invention discloses a mining electromagnetic valve control system with an intelligent power supply switch. The mining electromagnetic valve control system comprises a power conversion module and an electromagnetic valve, wherein the power conversion module adopts a switch power supply; a power supply switch controlled by a control module is additionally arranged between the power conversion module and the electromagnetic valve; the control module respectively controls the power supply switch and the electromagnetic valve besides outputting two paths of signals, and also receives a position sampling signal which is fed back from the electromagnetic valve; whether the voltage output by the power conversion module is exerted to the electromagnetic valve or not is determined by the control module according to a control request on the electromagnetic valve from the external part and a position signal which is fed back by the electromagnetic valve in real time so as to cut off and turn off the power supply switch.

Description

technical field [0001] The invention relates to the control of electromagnetic valves, in particular to a mine electromagnetic valve control system with an intelligent power supply switch, which is mainly used for the control of electromagnetic valves in mine spray dust suppression devices. Background technique [0002] Mining spray dust suppression device is mainly used in coal mine mining dust and ground coal washing field and other operating places. As the country pays more attention to mine safety production and occupational hazards, more and more attention is paid to the hazards of mine dust concentration, so the requirements for the prevention and control of mine dust are also getting higher and higher. In accordance with the requirements of coal mine safety regulations, sprinkler dust suppression devices or dust removal fans must be installed in mine alleys, coal outlets, reloading points, and coal unloading points. This system is applied to the sprinkler electromagn...

Problems solved by technology

[0004] The purpose of the present invention is to solve the defects that the existing control system is too simple, the electromagnetic valve is still energized when it is in standby, and the position error of the electromagnetic valve cannot be monitored in real time, and provides a mining electromagnetic valve control system with an intelligent power supply switch. Sampling of the valve position signal provides feedback for functions such as power-off protection and error reporting, thus avoiding standby power consumption and improving product reliability
