Anti-asphyxia device using the oxygen sensor

摘要

The present invention relates to suffocate prevention apparatus using an oxygen sensor, when the conventional vehicle is to take the water surface in a closed room losing the life or causes dizziness were the problems that hinder the operation bar, the subject innovation is in the room , install the idle state signal ECU (30) to input 20 of the signal and the engine of the oxygen sensor 10 for measuring the oxygen concentration, ECU (30) is the oxygen concentration measured during the idle state of the engine below a certain value If and able to output a control signal, a signal output and a switch terminal and a power window switch 40 and the timers 50 and the relay 2 (RY2), the relay 1 (RY1) to be ground by the serial connection, the relay 1 to be a warning buzzer (BZ) by a switch of a (RY1) it occurs, and the relay 2 by (RY2) are to be the window motor 60 by the switch of the relay 2 (RY2) operation that operates when the ground oxygen footwell If the alarm is low It will be generated and configured floss ventilation by opening the driver's window the amount.
