Abstract
The invention discloses a safety belt with a fatigue driving prompting function, which comprises a safety belt body; the heart rate sensor is arranged on the safety belt body and is right opposite to the heart position of a driver, and the heart rate sensor is used for detecting the heart rate of the driver and outputting a heart rate signal; the processor is in signal connection with the heart rate sensor and is used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and the alarm device is in signal connection with the processor and is used for generating a prompt signal when the driver is in fatigue driving. The safety belt can detect whether the driver is in a fatigue state in real time, and when the driver is judged to be in the fatigue state, the driver is advised to stop for a rest.
Description
Technical Field
The invention relates to the technical field of driving assistance systems, in particular to a safety belt with a fatigue driving prompting function.
Background
The driving fatigue refers to a phenomenon that a driver has a decreased driving skill objectively due to disorder of physiological and psychological functions after driving for a long time. The driver has poor or insufficient sleeping quality, and is easy to have fatigue when driving the vehicle for a long time. Driving fatigue affects the driver's attention, feeling, perception, thinking, judgment, consciousness, decision and movement. The factors that cause fatigue driving are manifold. Fatigue of drivers is mainly fatigue of nerves and sense organs, and fatigue of limbs caused by poor blood circulation due to long-term fixed posture. When a driver sits on a fixed seat for a long time, the action is limited to a certain degree, the attention is highly concentrated, the driver is busy judging stimulation information outside the vehicle, and the mental state is highly tense, so that the driving fatigue phenomena of blurred eyes, waist soreness and backache, slow response, inflexible driving and the like occur. The order of fatigue development is: it is also a considerable aspect that the eyes, neck, shoulders, waist, mainly the fatigue of the eyes and body and also the brain.
The existing eyeball tracking anti-fatigue technology can generally directly control the automobile to be flameout after multiple reminding or ineffective reminding after detecting the fatigue driving of a driver, and the direct flameout of the running vehicle has great influence on the rear vehicle, thereby easily causing safety accidents.
Disclosure of Invention
The object of the present invention is to provide a safety belt which can prevent fatigue driving of a driver.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a seatbelt with a fatigue driving prompting function, comprising: a seat belt body; the heart rate sensor is arranged on the safety belt body and is right opposite to the heart position of a driver, and the heart rate sensor is used for detecting the heart rate of the driver and outputting a heart rate signal; the processor is in signal connection with the heart rate sensor and is used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and the alarm device is in signal connection with the processor and is used for generating a prompt signal when the driver is in fatigue driving.
Further, the safety belt body is provided with an irritant gas sprayer, and the irritant gas sprayer is in signal connection with the processor.
When the processor judges that the driver is in a fatigue state, the processor sends a starting signal to the irritant gas sprayer, and the irritant gas sprayer sprays irritant gas to the driver.
Compared with the prior art, the invention has the following technical effects:
according to the safety belt, the heart rate sensor is arranged on the safety belt body, the safety belt body is fastened to the body of a driver when the driver drives an automobile, and the heart rate sensor is right opposite to the heart position of the driver, so that the heart rate sensor obtains a real-time heart rate signal of the driver through the contact with the chest of the driver, and the processor processes the heart rate signal obtained by the heart rate sensor to judge the fatigue degree of the driver; when the processor judges that the driver is in a fatigue state, the processor controls the alarm device to generate prompt information; the invention can detect whether the driver is in the fatigue state in real time, and advises the driver to stop for rest when judging that the driver is in the fatigue state.
For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic view showing the construction of a seatbelt with a fatigue driving prompt function according to the present invention.
Detailed Description
Referring to fig. 1, a safety belt with a fatigue driving prompting function includes a safety belt body; the heart rate sensor is arranged on the safety belt body and used for detecting the heart rate of a driver and outputting a heart rate signal; the processor is in signal connection with the heart rate sensor and is used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and the alarm device is in signal connection with the processor and is used for generating a prompt signal when the driver is in fatigue driving.
Preferably, the safety belt body is provided with a vehicle speed detection device and an irritant gas sprayer, and the vehicle speed detection module and the irritant gas sprayer are respectively in signal connection with the processor.
When the vehicle speed detection module detects that the running speed of the vehicle is greater than 0 and the processor judges that the driver is in a fatigue state, the processor sends a starting signal to the irritant gas sprayer, and the irritant gas sprayer sprays irritant gas to the driver.
According to the safety belt, the heart rate sensor is arranged on the safety belt body, the hands of a driver press the safety belt body for a long time when the driver drives a car, the heart rate sensor obtains a real-time heart rate signal of the driver through the contact with the hands of the driver, and the processor processes the heart rate signal obtained by the heart rate sensor to judge the fatigue degree of the driver; when the processor judges that the driver is in a fatigue state, the processor controls the alarm device to generate prompt information; the invention can detect whether the driver is in the fatigue state in real time, and advises the driver to stop for rest when judging that the driver is in the fatigue state.
Furthermore, an irritant gas sprayer connected with the processor is arranged on the safety belt body; when the processor judges that the driver is in a fatigue state, the processor controls the exciting gas sprayer to be started to spray exciting gas to the driver, so that the driver is prevented from neglecting the prompt information and continuing driving.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
