Method and device for high-sensitively receiving and transmitting integrated infrared detection of driver's fatigue

The invention relates to a method and a device for high-sensitively receiving and transmitting integrated infrared detection of driver's fatigue. The method comprises the following steps: emitting an infrared ray by an infrared sensor, detecting eye movement characteristics of a driver through receiving change of infrared light value after irradiating at people's eyes and reflecting; analyzing and calculating the driver's fatigue in driving process according t the relationship analysis between the eye movement and the fatigue. A smart detecting data processing unit receives the driver's eye change characteristic data, environmental light sensitive data and head part behavior data information collected by a fatigue parameter detecting identifying unit; the intelligent detecting data processing unit compares the processed result with the self-studied regular characteristic model of the driver, analyzes and calculates the P80 state value of the driver; when the P80 state value exceeds the safety threshold, the intelligent detection data processing analyzing unit can feedback the information to a back end data center through a Bluetooth communication module, and starts an early/warning/interference method, such as shock, stimulated audio.

Driving light warning method, device and equipment and storage medium

The invention belongs to the technical field of automobiles and discloses a driving light warning method, device and equipment and a storage medium. The method comprises the following steps of acquiring light intensity acquired by a light intensity acquisition sensor, and comparing the light intensity with a preset light intensity threshold value; when the light intensity is greater than a preset light intensity threshold value, acquiring the eye change information of the driver; and when the eye change information meets a preset condition, a high beam warning system of the vehicle being started for lamplight warning. When the light intensity is larger than the preset light intensity threshold value, the eye change information of the driver is obtained, and when the eye change information meets the preset condition, the high beam warning system of the vehicle is started for lamplight warning. Compared with an existing mode that whistling warning is conducted when the light intensity reaches the preset threshold value, the method is advantaged in that whether the change of the light intensity affects driving of a driver or not is recognized more accurately, then light warning is started, warning efficiency is improved, and warning starting caused by misjudgment is avoided.
