Hereinafter, with reference to the drawings, the operation and effects of the emergency situation notification device using a weight sensor according to a preferred embodiment of the present invention will be described in detail.

As shown in FIG. 3, when the emergency situation notification mode function of the notification mode selection / release unit 100 is selected from the passenger inside the vehicle in step 100, the control unit 600 proceeds to step 102. In step 102, the control unit 600 measures the oxygen concentration in the vehicle through the oxygen measurement sensor 210 and proceeds to step 104. In step 104, the controller 600 compares whether the oxygen concentration in the vehicle measured in step 102 has a value less than or equal to a preset value. As a result of the comparison, if the measured oxygen concentration in the vehicle exceeds the preset value, the controller 600 proceeds to step 102 and continuously measures the oxygen concentration in the vehicle through the oxygen measurement sensor 210 and compares it with the preset value.

If the in-car oxygen concentration measured in step 104 is equal to or less than a preset value, the controller 600 proceeds to step 106 and detects the weight of the vehicle seat through the weight sensor 220 and proceeds to step 108. In step 108, the controller 600 compares whether the weight of the vehicle seat detected in step 106 has a value greater than or equal to a preset value. As a result of the comparison, if the vehicle seat weight detected in step 108 is less than or equal to a predetermined threshold, the controller 600 proceeds to step 118 to release the emergency notification mode.

If the weight of the vehicle seat detected in step 108 is greater than or equal to a predetermined value, the control unit 600 proceeds to step 110 to control the cooling / heating system 310 to turn off the operation of the cooling / heating device. In addition, the controller 600 proceeds to step 112 to control the ventilation system 320 so that the two windows are automatically lowered through the wire harness. Thereafter, the controller 600 proceeds to step 114 to control the radio system 330 to turn on the radio.

During operation of the radio, the controller 600 determines whether there is a key input corresponding to the emergency notification mode release function in step 116. If there is a key input corresponding to the emergency notification mode release function, the control unit 600 proceeds to step 118 to release the emergency notification mode.

If there is no key input corresponding to the emergency notification mode release function in step 116, the controller 600 proceeds to step 120 and determines whether the operation time of the radio exceeds a preset input time. If it is determined that the operation time of the radio does not exceed the set time, the control unit 600 proceeds to step 116 to continuously determine whether there is a key input corresponding to the emergency notification mode function.

If the operation time of the radio exceeds the preset time input in step 120, the controller 600 proceeds to step 122 to measure the pulse rate of the occupant through the pulse measuring sensor 230 and proceeds to step 124. In step 124, the controller 600 compares the measured pulse rate of the occupant with the normal pulse rate previously input and set to determine whether the pulse rate of the occupant is normal. If it is determined that the occupant pulse rate is normal, the controller 600 proceeds to step 122 and measures the occupant pulse rate again.

If the pulse rate of the occupant is not normal, the control unit 600 proceeds to step 126 and includes the current location information of the vehicle and the emergency message inputted through the call number and the wireless transmitter / receiver 500 of the rescue center. The request information is controlled by the wireless transmitter / receiver 600 to modulate the structure request information and then wirelessly transmits through the antenna.

In this case, the rescue center terminal demodulates and displays the rescue request information that is subsequently input when the call number is received, and the monitor personnel checks the received rescue request information and promptly inputs the rescue personnel to the site. Can be released from the situation.

Although the present invention has been described with respect to the preferred embodiment, various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the invention should not be defined by the described embodiments, but by the equivalents of the claims and claims.
