Drive Fatigue Detection Device
Fatigue Detection Technology is utilizing intelligent video analysis technology to make real-time judgment and analysis of human eyes, to judge the fatigue status of the detected person by the closing of human eyes, and to send fatigue alerts and alarms according to the set rules.
Fatigue Detection System consists mainly of surveillance cameras and intelligent video analysis devices. After using the cameras to shoot human face and accurately locate human eyes, system will automatically judge and analyze the closing of human eyes in combination with the preset detection rules, and then judge the fatigue status of the detected person accordingly. When the eyes closing time reaches the alarm level, system will automatically give out alarm sound to alert the detected person. If the situation is worse, system will notify the backstage monitoring center of the alarm via networks.
1. Features
- Accurate eyes status recognition: identify the status of eyes opening and closing accurately.
- High indentifying frequency: more than 20 times' indentifying of eyes status per second.
- Embedded DSP platform needs no hosting and assistance of computers.
- The criteria of fatigue detection can be manually set according to the practical need, which makes it quite flexible and convenient to use.
- The ability to transmit the alert data to back-end monitoring center via cable network or wireless network (2G/3G); relevant parameters can be remotely set by phone messages in wireless network;

3. Applications
The main function of Fatigue Detection System is to detect the extent of human's fatigue and send alert information to the detected person. It is mainly applied in vehicles to avoid dangers caused by fatigue driving, especially for drivers of following vehicles:
- Long-haul passenger buses
- Cargo transport vehicles
- Dangerous goods transport vehicles
Computerized engine control systems have a certain amount of built-in self-diagnostic capability to detect problems that affect engine performance and emissions. The same is true for the antilock brake system and other onboard systems that are computer controlled.

OBD-II
When a fault is detected, the computer will store a diagnostic trouble code in its memory and illuminate the "Check Engine" light. On some vehicles, the computer can be put into a special diagnostic mode by grounding certain terminals on a diagnostic connector. This will cause the Check Engine or other lights to flash out the fault code. On many vehicles, though, a scan tool must be plugged into the computer system to access and read the codes.
