Health apparatus control system transforms direct current power to alternating current power of appropriate frequency to decide number of peripheral device such as electric fan to be started according to electric power

摘要

Direct current (DC) power generated at a health apparatus (1) is transmitted to an intelligent controller (2). A voltage controlling oscillator (VCO) (21) in the controller, transforms DC power into AC power of appropriate frequency. The analog digital converter (ADC) (22) in the controller, decides the number of peripheral devices such as electric fan (31-3n) to be started according to the electric power.
