Design of the Control System for High-Altitude Descent Control Device

Traditional descent control device is generally just mechanical structure and lack of real-time control of running status for descent control device, having a lot of inconvenience to high-altitude rescue. The paper presents a control system of descent control device based on SCM (Single Chip Microcomputer), realizing the effective control of descent control device. The system use PWM to control the speed of the DC motor, use electromagnetic brake to realize stop in midway, and use digital remote-control system to realize real-time control of running status for descent control device. Meanwhile, this paper gives a function module for itself charge-discharge, increasing energy efficiency. The structure of the system is simple, reliable and sensitive.
