Developing and designing of a new passive aerobic exercise bed

The paper introduced a new passive aerobic exercise bed. The bed applied ATmega series AVR single-chip microcomputer and acted Atmel Company chip-Mega16 as its core including control circuits of permanent magnet DC motor, infrared remote control circuits, LCD module, caution module, and temperature control module, and so on. The designer used the Altium Designer to design the system, simulate the results, draw the PCB boards, program the C composition according to functions of timer interruption, I/O input-output of the chip mega16 in the condition of ICCV7 for AVR. At last, the new passive aerobic exercise bed realized the precise control in various functions.
