Abstract
Based on the double-loop DC motor speed automatic control system works, the paper design and research the coal mine hoist DC converter system. Through the elevator shaft DC transmission control system triggers the transformation of the traditional analog to digital trigger into digital trigger. Improve the elevator control system stability, fast, reliability, and to make it easier for system maintenance. Applicable to all kinds of harsh environment of the mining system.
By the author of the main circuit design, control circuit design, MCU trigger circuit design, and supporting a complete circuit design to meet the requirements of the elevator shaft DC drive control system. And design in various sectors have carried out detailed calculations and the parameters of the original selection, which can effectively guide the automatic control system, electrical and other subjects of learning and teaching, and in actual systems such as various types of mine hoist the design and debugging in the Better guide
