<p>PURPOSE: An unmanned automatic control device for saving carbon dioxide and a driving method thereof are provided to effectively control carbon dioxide generated from lamps and electric heaters in places where many and unspecified persons are used, or vehicles in underground parking lots. CONSTITUTION: An unmanned automatic control device for saving carbon dioxide comprises a monitoring part(11), a calling part(12), a communicating part(13), a MCU(21), a body sensing part(22), a carbon dioxide sensing part(23), a voice communicating part(24), and a lamp and fan control part(25). The monitoring part indicates whether a switchboard, installed in a parking lot, drives or not. The calling part calls a person in charge of the parking lot according to control signal of the monitoring part. The communicating part detects signals delivered from the MCU and transmits to the monitoring part. The MCU applies power to the body sensing part and the carbon dioxide sensing part according to the control signal of the monitoring part. The body sensing part detects movement of people or vehicles in a real time. The voice communicating part transmits and receives emergency alarm and voice signal in the parking lot.</p> |
