Design of a New Type of Electromagnetic Valve Driver for Hydraulic Support

In view of problems of single function and no information collection function existed in traditional electromagnetic valve driver of hydraulic support electro-hydraulic control system , the paper put forward a design scheme of a new type of electromagnetic valve driver for hydraulic support, and introduced hardware composition, design of internal circuit and software of the driver. The driver has been successfully used in working face of automatic combination cutting-and-conveying unit and automatic coal plough unit, and has stable and reliable in running.
