Function Of Drowsiness Detection System

•This system recognizes the operator's face with the drowsiness detection camera. If the Driver Status Monitor judges from the movement of eyelid or direction of face that the operator has a drowsiness, sleeps for a short time, looks aside, or loses the balance, the drowsiness alarm buzzer and notification sound occur to give a warning to the operator, to support the safe operation.

•This system starts at the same time as you turn the starting switch to the ON position. Also, it stops at the same time as you turn the starting switch to the OFF position.

•You can check the operation status of this system by the lighting status (light up/flash/go off) of the drowsiness detection system ready lamp.

•If the driver status monitor senses that the operator sleeps for a short time, looks aside, loses the balance, or has a drowsiness, the information is stored to the translator controller as a failure code.

•The stored information as a failure code is transmitted from the KOMTRAX Plus controller via the retarder controller to the server.

OPERATION OF DROWSINESS DETECTION SYSTEM Preparation state

The system is started and starts the self-diagnosis when the starting switch is at the ON position. After the selfdiagnosis is completed and the system is started normally, the operation notification sound (Three short beeps) occurs, and the status goes to the normal operation state. When a failure is sensed

When the Driver Status Monitor sensed

•The failure notification sound occurs from the notification sound speaker.

•Keep the preparation state.

When other than the Driver Status Monitor sensed

•The failure code is shown on the machine monitor.

•Keep the preparation state.

Normal operation state

The system senses no abnormality and operates normally. The state is as follows.

•The drowsiness detection system ready lamp lights up.

•The operation notification sound and drowsiness alarm buzzer do not occur.

•If a failure is sensed during the normal operation state, the status changes to the preparation state.

Alarm state

When short time sleep and drowsiness are sensed

The system judges that the operator sleeps for a short time or the drowsiness of operator is above the specified level during the travel. The state is as follows.

•The drowsiness detection system ready lamp flashes.

•The alarm notification sound and drowsiness alarm buzzer occur.

•If a failure is sensed during the alarm state, the status changes to the preparation state. When inattentive driving and loss of balance are sensed

The system judges that the operator looks aside or loses the balance during the travel. The state is as follows.

•The drowsiness detection system ready lamp flashes.

•The alarm notification sound occurs.

•If a failure is sensed during the alarm state, the status changes to the preparation state. You can release the alarm state with one of the conditions that follow.

•When the system judges that the operator has no more short time sleep, inattentive driving, loss of balance, and drowsiness.

•When the travel speed becomes below 1km/h.
