Driver fatigue monitor with signal output 45km/h start-up speed
Fatigue plays a major factor in crashes in the UK, one study found that 1 in 6 crashes resulting in death or injury on major roads are fatigue related. It is reported that about 40% of professional drivers, especially HGV drivers report increased levels of sleepiness which can result in a disproportionately high number of fatigue related accidents.
Fatigue related accidents can occur when commercial drivers have a lack of stimulation. The most common roads where this is likely to happen are motorways and dual carriageways. Sleepiness reduces reaction time, alertness and concentration which severely affects the driver’s ability to process information quickly enough.
Some common warning signs of fatigue includes – increased difficulty concentrating, yawning and heavy eyelids. These are signs of micro sleep. This is when the driver nods off for between 2-30 seconds without realising.
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.
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.
