Description

{Drowsy driving prevention system}

The present invention relates to a system for preventing drowsy driving, which is a technology that allows a driver of a vehicle to check his or her current driving condition in real time while driving and receive the results through navigation, thereby enabling immediate response to an arising situation.

One of the things that commonly annoys drivers while driving is drowsy driving.

Meanwhile, warning signs of drowsy driving include frequent blinking or yawning, blurred vision, and difficulty lifting one's head.

Also, there is a tendency to weave in and out of lanes and stick close to the car in front, so it is safe to open the windows wide or move to a rest area.

These warning signs of drowsy driving often lead to major traffic accidents in moments when you are not aware of them, which can be fatal to you and other drivers, resulting in loss of life.

To prevent this, a drowsy driving prevention system is needed.

These drowsy driving prevention systems do not mention specific details such as identifying a driver's specific level of drowsiness when checking the driver's drowsiness, but simply detect whether the driver is drowsy and provide recognition through vibrations accordingly.

Accordingly, since there is no specific standard for judging drowsy driving when detecting such cases, the detection of drowsy driving is bound to be different for each user of this technology depending on their condition, making it difficult to accurately identify drowsy driving.

The present invention provides a system for preventing drowsy driving that allows a driver of a vehicle to check his or her current driving status in real time while driving and receive the results through navigation, thereby enabling immediate response to an arising situation.

Hereinafter, a preferred embodiment of the present invention for achieving the above purpose will be described with reference to FIGS. 1 to 9 with reference to the attached drawings.

First, the drowsy driving prevention system of the present invention, as illustrated in FIG. 1 or FIG. 3, comprises: a server (100) that operates automatically or manually according to the administrator's settings; a navigation system (200) that is installed inside a vehicle and is interconnected with the server (100) and performs current location identification, route guidance, and drowsiness warning; a smartphone (300) that is interconnected with the server (100) and has an application (310) installed thereon and carried by the driver of the vehicle; glasses (400) that are worn by the driver of the vehicle and are interconnected with the smartphone (300) to detect drowsy driving; and is configured to transmit a signal detected by the glasses (400) to the server (100) via the smartphone (300), and to transmit the server (100) to the navigation system (200) by comparing the received value with a preset value and outputting the result value as voice or text.

At this time, as shown in FIG. 2, the glasses (400) are configured with a CO2 measurement unit (410) for checking the CO2 status inside the vehicle in real time, a status check unit (420) for measuring the heart rate and pupil status of the vehicle driver in real time, and a smartphone transmission unit (430) for transmitting the measured results from the CO2 measurement unit (410) and the status check unit (420) to a smartphone (300). By transmitting the measured values from the CO2 measurement unit (410) and the status check unit (420) to the smartphone (300), the smartphone (300) transmits the information back to the server (100).

Here, the server (100) is configured with a comparison unit (110) that compares the measured results from the CO2 measurement unit (410) and the status check unit (420) received from the smartphone (300) with a preset value, as shown in FIG. 2, a judgment unit (120) that determines the error range between the preset value and the measured value, and a navigation transmission unit (130) that transmits the determined result value to the navigation (200), thereby transmitting the accurately compared result value.

As shown in Fig. 2, the navigation (200) is provided with an output unit (210) that outputs the result value received from the navigation transmission unit (130) as voice or text, so that the user can recognize the output information and perform various actions, such as stopping, as needed.

Meanwhile, the output unit (210), as shown in Fig. 2, is configured to output the CO2 measurement results as good, average, drowsy, or bad in voice or text, and to output the heart rate and pupil state measurement results in voice or text.

At this time, the vehicle driver can optionally set the voice or text output as needed.

In addition, the output unit (210) can output a warning sound or message again after a certain period of time has passed after receiving a warning sound or message according to the CO2 measurement or heart rate and pupil condition, so that it can be output repeatedly several times in case the vehicle driver does not recognize it at once.

The above output unit (210) can prevent traffic accidents that may occur by continuously warning the driver, thereby ensuring driver safety.

In addition, although not shown, the server (100) measures the CO2 or heart rate and pupil condition of the driver of the vehicle again after a certain period of time and transmits the results to the navigation (200), thereby informing the driver of whether or not he or she is in a continuous state of drowsiness.

Meanwhile, the application may further include a My Menu that allows the user to change their profile and information, connect to the customer center, and connect to the COVID-19 information center. However, when an application user registers an inquiry, the administrator may confirm the response and automatically be notified of a problem that has been resolved or an unresolvable response.

That is, in the case of these My Menus, it is a concept of a space where communication between application users and operators can take place.

The method of using the above-mentioned drowsy driving prevention system will be explained with reference to FIGS. 3 to 9.

You can register as a member using the application installed on your smartphone. When registering as a member, you will go through the normal membership registration process. For security reasons, you will need to verify your mobile phone number and enter a PIN number to register the product. The product here refers to a smartphone.

After that, the driver will use the navigation to search for the desired location and be guided through the route, but if drowsiness is detected, a warning message or notification sound will be provided.

When a driver runs an application to detect drowsiness and requests CO2 measurement, heart rate, and pupil condition check, the glasses check the CO2 measurement, heart rate, and pupil condition and transmit the information to the application, which then transmits it to the linked server.

After that, the server compares the C02 measurement result with the preset value, and based on the comparison value, informs the member in real time whether he or she is good, average, sleepy, or bad. This output is output through navigation.

In addition, the heart rate and pupil condition are measured by checking the driver's condition for 1 minute through glasses (400), and the results are sequentially transmitted in the order of application (300) - server (100) - navigation (200) to provide notification.

At this time, the output form of the output unit (210) is output in the form of voice or message, and can be selected and set by the vehicle driver as needed.

According to the drowsy driving prevention system of the present invention, the current state of the driver of the vehicle is accurately checked in real time, compared with the preset value, and if it deviates from the error range, the driver is notified of this and is guided to stop on the shoulder of the road or enter a rest area, thereby preventing traffic accidents.
