“…When one clenched the rope and then slow down altitude with slow-descent rescue apparatus [7,8], the rope pull the overdrive gear and drive the permanent magnet generator rotor to rotate in a high-speed. The stator coils generate power; form a closed loop with the external power thermal resistance and convert electrical energy into heat energy dissipated in the air to result in current.…”

“…Therefore, we introduce intelligent controlling algorithms to automatically adjust the duty ratio of PWM wave for different weight of bodies and realize constant speed. The literature [7] carries out research on intelligent control method of high building rescue apparatus based on fuzzy control theory. It used the photoelectric sensor to achieve smart adaptive adjustment control of descending speed and distance.…”

t firstly set up energy converting control model of high building rescue apparatus (HBRA), and developed a controller of the HBRA by using AVR micro computer unit (MCU), designed the control circuits for electric energy converting to thermal energy, then developed program to generate the PWM control wave. At last, it tested the PWM output wave of the controller, and experimented on the HBRA with the controller on loads of 15kg and 25kg. The results proves the controller can automatic adjust the duty ratio of PWM wave according to the different loads, which can keep the slow-down velocity constant of the loads and help people rescue from high buildings in emergency such as on fire.
