Description

safety bag {SAFETY BAG}

The present invention relates to a safety bag for children or students, and in detail, by providing an LED light emitting lamp that operates (lighting or blinking) according to the ambient brightness in the bag body, children or students returning home from school or academy at night in the dark It relates to a safety bag that can promote the safety of children and students from mobile devices such as automobiles, motorcycles, bicycles, or quick boards by allowing them to be easily identified from a distance.

In the past 10 years in Korea, the number of deaths caused by traffic accidents (transport accidents) has been on the decline. However, when looking at the death trend by accident type of children under the age of 14 from 2014 to 2018, it is reported that the death rate from traffic accidents is still very high, which is about 1.1 times higher than the average of OECD countries.

The traffic accidents of these students mainly occur during the day when there is a lot of movement, but it tends to occur frequently even at night when there is a relatively small amount of movement. The reason is that the number of students returning home from school or academy late at night is large, and the driver's attention is reduced due to the narrow viewing angle and high fatigue at night compared to the daytime.

Recently, the number of motorbikes driving illegally in India is increasing due to the increase in delivery orders due to the impact of coronavirus infection-19 (COVID-19). As the number of board users increases, the safety of students when walking at night is more threatened.

Accordingly, in order to prevent traffic accidents at night, pedestrians must choose a place with road lighting or a bright place to walk. In addition, it is effective to wear brightly colored clothing or to carry a reflector separately so that the driver can easily identify it. However, it is difficult for young students to perform well because it is cumbersome and tedious to always wear brightly colored clothes or to carry a separate reflector.

In order to solve this problem, Korean Patent Laid-Open No. 10-2016-0024595, Korean Patent No. 10-1096621, etc. attach a light emitting body LED to the bag body to provide lighting at night, so that students can be easily identified. A safety bag was proposed.

However, in safety bags according to the prior art proposed in Korean Patent Laid-Open No. 10-2016-0024595 and Korean Patent No. 10-1096621, it is a simple technology that provides lighting at night through an LED light emitting body attached to the bag body. There were the following problems.

First, as it consists of a configuration in which the student must manually operate the switch to operate the LED illuminator attached to the body of the bag, it is not possible to safely protect the student if the LED illuminator is not operated because the surrounding is darkened. .

Second, it is a configuration that provides lighting by operating the LED light-emitting body attached to the body of the bag. Although the driver can identify the student through the light, there is no means for the student to recognize the dangerous situation when a dangerous situation occurs. There was a limit to promoting the safety of

In particular, when walking at night, students tend to put earphones in their ears and move while listening to music, so they cannot recognize dangerous situations around them, including the sound of a car horn, so the function to safely protect students from dangerous situations is It was insufficient.

Third, when a dangerous situation occurs to a student, there is no means for the guardian to recognize the current location of the student, so it is difficult to respond quickly after the danger occurs.

The controller 14 may be implemented using, for example, an Arduino. The Arduino includes a microcontroller that controls the operation of receiving input values from various switches or sensors and outputting them to electronic devices such as the LED light emitting lamp 13 or a vibration motor.

The control unit 14 receives power from the battery (power unit) 15 built in the bag body 11 and operates the LED light emitting lamp 13 . At this time, the LED light emitting lamp 13 may be turned on for a set time in response to an operation signal of the control unit 14 or may be flickered at a predetermined period.

The battery 15 may be, for example, a rechargeable battery that can be charged, and is electrically connected to the board on which the control unit 14 is mounted, that is, a printed circuit board (PCB) to supply power to the control unit 14 .

The control unit 14 operates the LED light emitting lamp 13 when the ambient brightness sensed through the light sensor 17 is less than the set brightness while the operation switch 16 is turned on.

As the light sensor 17, for example, an illuminance sensor may be used. The light sensor 17 is a device whose output value changes according to ambient brightness, and when the operation switch 16 is turned on, it operates by receiving power from the battery 15 . Then, after detecting the ambient brightness in real time, a signal corresponding to the detected ambient brightness information is transmitted to the controller 14 .

Meanwhile, the control unit 14 may be configured to automatically operate the LED light emitting lamp 13 when a set time arrives in addition to the ambient brightness transmitted from the light sensor 17 . To this end, the safety bag 10 according to an embodiment of the present invention may further include a timer 18 .

For example, the timer 18 has a set sunset time for each season, and when the sunset time set by the timer 18 arrives, the controller 14 receives an operation signal output from the timer 18 and emits LED light. The lamp 13 is operated. That is, according to the sunset time set for each season, the LED light emitting lamp 13 may be automatically turned on to turn on or blink.

In addition, the safety bag 10 according to the embodiment of the present invention, as shown in Figure 4, the surrounding sound, for example, a horn sound generated from a car, motorcycle, or bicycle, or the sound of a person shouting, etc. It may further include a sound detection sensor 19 to detect.

The sound sensor 19 is a sensor for detecting various sounds generated in the vicinity, and may be, for example, a sensor for detecting the amplitude (decibel) of the ambient sound.
