Description

How Do Drivers Alert Systems Work?

Drivers alert systems are closely related to lane departure warning systems, in that most of them function by keeping visual track of lane markings to identify any deviations from the lane. While lane departure warning systems are designed to prevent deviation under any and all circumstances, drivers alert systems are specifically aimed at identifying signs of driver fatigue.

Rather than triggering only when a vehicle is in danger of straying from its lane, these systems look for the sort of erratic movement typically associated with an impaired driver.

Other systems take it a step further by monitoring the driver’s eyes and face for signs of drowsiness. If the system determines that the driver is having trouble staying awake, it may take corrective action.

The simplest driver alert systems are typically mounted to the driver's head, like an earpiece, and use a simple motion or tilt sensor. If the driver's head nods, the device will usually sound an alarm.

I/O and RS232 output optional:

I/O output is only a high/low voltage output, you can get only the alarm signal,the connection is easy. The default setting is high resistance status under normal status, low voltage output when triggered.

RS232 output has alarm signal and picture output, thus you can get the driver's face picture in the center, it need to integrate to the GPS system via protocol.

Power input and output

1. Input: 9-36V, LS803 is suitable for both 12V and 24V vehicle, and have good high voltage protection.
2. very lower power consumption, average current less then 100mA in 12V car, and 60mA in 24V car, similar with leakage from the battery, almost does not consume battery power.
3. I/O output, high resistance status under normal status, low voltage output when triggered.
4. Working Temprature: 0-80℃
5. Working Humility: 10%-90%
6. Weigh:108g
7. Demension: 4.5*10.2cm

Attention:

Non-authorized person, please do not open or repair the device.

Please do not operate the system when driving to avoid dangerous

Please handle carefully, do not drop or impact with hard objectives

Do not use chemicals or cleaning agents to clean the machine, it will damage the machine surfaces or rust the paint.

keep it away from water or moist place, device will be rusted or shortcut in those area.

Do not rip, bend or squeezed the wiring by heavy object, or it will be hot to fire.
