Intelligent Control Method Research on the High-Rise Buildings Rescue Apparatus

The working principle of self-generating electricity high-rise buildings slow-down rescue apparatus uses steel string to drive the permanent magnetism rotor rotate with a high speed by the speed-up gear groups, which will cut the stator coils and generate electricity, and realize potential energy transmitting to electricity energy. It has developed an intelligent control system of the rescue apparatus with the AVR microcomputer unit (MCU). By using the photoelectric coupler to control open or close of the power triode, which can control the power resistances connected into the electricity-thermal converting circuits whether or not and realize the adjustment control of the electricity-thermal conversion. Photoelectric sensor measures the pulse signals with the gear and sends them to the AVR MCU, and the intelligent program will calculate out the mean falling velocity of human body by the signals, then call the fuzzy control sub program and automatically adjust the power resistance suitably to control ratio of the electric energy transmitting into the thermal energy and scattered into the air, realize adjusting the potential energy transmitting into the kinetic energy, and make the falling velocity of human body from high-rise buildings approach the limit velocity set by the intelligent program. At last, it has finished the falling experiments on the rescue apparatus with 15kg and 25kg load, and the results proves the intelligent rescue apparatus can realize self-adaptive control the slow-down velocity from high-rise buildings according to different load, and has better slow-down rescue effect.
