Description

IoT 기반 다인승 차량 내 영유아용 카시트의 착석 및 안전띠 착용 원격 모니터링 시스템{System for monitoring the seating and belt fastening for infant car seats in multi-seater vehicles based on IoT}System for monitoring the seating and belt fastening for infant car seats in multi-seater vehicles based on IoT}

본 발명은 다인승 차량 내에 설치되는 영유아용 카시트의 착석 및 안전띠 착용여부를 IoT(Internet of Things) 기반으로 원격 모니터링하는 시스템에 관한 것으로, 보다 상세하게는 다인승 차량 내 영유아용 카시트의 착석 및 안전띠 착용 감지를 위한 착석센서 및 안전띠센서를 설치하고 이들 센서신호를 블루투스 비콘 등의 근거리 무선통신을 통해 모니터링 화면으로 표출할 수 있도록 함으로써 관리자로 하여금 스마트폰 등의 어플리케이션 또는 차량 내 모니터링 패널을 통해 영유아용 카시트의 착석 및 안전띠 착용여부를 확인하고 즉각 조치 가능하게 하여 ioT 기반의 안전하면서도 실질적인 안심 보육환경을 조성할 수 있게 하는 IoT 기반 다인승 차량 내 영유아용 카시트의 착석 및 안전띠 착용 원격 모니터링 시스템에 관한 것이다.The present invention relates to a system for remotely monitoring the seating of a car seat for infants and young children installed in a multi-passenger vehicle and whether or not a seat belt is worn based on IoT (Internet of Things), and more particularly, to a system for remotely monitoring the seating of a car seat for infants and young children installed in a multi-passenger vehicle and the wearing of a seat belt. Seating sensors and safety belt sensors are installed to detect wearing, and these sensor signals can be displayed on the monitoring screen through short-range wireless communication such as Bluetooth beacons. It is about a remote monitoring system for car seat seating and seat belt wearing for infants and toddlers in an IoT-based multi-seater vehicle that can create an ioT-based safe and practical childcare environment by checking whether a car seat is seated and whether a seat belt is worn and taking immediate action. .

최근 전좌석 안전띠 착용 의무화가 추진되면서 어린이집이나 유치원 등의 등,하원에 이용되는 영유아용 또는 아동용 통학 차량의 경우에도 영유아 또는 아동용 카시트와 안전띠의 장착이 필수적이며, 이러한 영유아 또는 아동용 카시트에 장착되는 안전띠는 2점식 또는 5점식이 있다. With the recent promotion of mandatory wearing of seat belts for all seats, it is essential to install car seats and seat belts for infants or children even in the case of school vehicles for infants or children used for daycare centers, kindergartens, etc., etc. is a 2-point or 5-point type.

2점식 안전띠는 도 1의 (a)에 예시된 바와 같이 탑승자의 하복부와 흉부를 좌석에 안정되게 고정하는 역할을 하므로 사고시 상체를 보호해주지 못하여 머리가 크게 흔들릴 우려가 있고 허리나 장기에도 심각한 피해를 줄 수 있으며, 체구가 작은 경우 튕겨나갈 우려가 있다.As shown in (a) of FIG. 1, the two-point safety belt plays a role in stably fixing the occupant's lower abdomen and chest to the seat, so it cannot protect the upper body in an accident, so there is a risk of head shaking and serious damage to the waist or organs. It can be given, and if the body is small, there is a risk of bouncing.

반면에 5점식 안전띠는 도 1의 (b)에 예시된 바와 같이 탑승자의 상체와 흉부 및 하복부를 좌석에 안정되게 고정하는 역할을 하므로 사고시 2점식 안전띠보다 부상 또는 사망확률을 줄일 수 있다.On the other hand, the 5-point safety belt serves to stably fix the occupant's upper body, chest, and lower abdomen to the seat, as illustrated in (b) of FIG.

한편, 최근에는 영유아용 또는 아동을 사고로부터 보호하기 위해 영유아용 또는 아동용 통학차량의 경우 출고시 추가 옵션이나 추후 설치를 통해 착석 여부를 확인하거나, 안전띠 미착용을 경고하는 등의 여러 안전장치 등이 탑재되기도 하며, 보조교사 또는 도우미 등이 차량에 동승하여 영유아 또는 아동의 탑승, 착석 및 안전띠 착용, 하차를 지도하고 확인하도록 함으로써 사고로부터 탑승자를 보호하도록 하고 있다. 그러나 차량의 연식이 오래되어 추가 옵션이 없거나 추후 설치가 안되거나 지입용 차량 등의 경우에는 전좌석에 영유아용 또는 아동용 좌석을 장착할 수 없으며, 장착한다고 하더라도 그만큼 많은 부분의 개조가 필요하여 높은 비용이 발생하기 때문에 장착을 꺼리고 있다.On the other hand, in recent years, in order to protect infants or children from accidents, school vehicles for infants or children are equipped with various safety devices such as checking seat availability through additional options or later installation at the time of shipment, or warning of not wearing seat belts. In some cases, an assistant teacher or helper accompanies the vehicle and guides and checks the boarding, seating, wearing of a seat belt, and getting off the vehicle to protect the occupants from accidents. However, if there are no additional options due to the age of the vehicle, or if it is not possible to install it later, or in the case of a vehicle for holding, it is not possible to install seats for infants or children in all seats, and even if they are installed, remodeling of many parts is required, resulting in high cost. I am reluctant to install it because of this.

이와 관련하여 대한민국 등록특허 제10-1894058호(2018.08.27.등록; 이하 '특허문헌1'이라 약칭함)에는, 열유속 센서를 이용한 생체 검지기, 차량용 착석 검지기 및 시트 벨트 미착용 경고 시스템에에 관한 기술이 공지되어 있다.In this regard, Republic of Korea Patent Registration No. 10-1894058 (registered on August 27, 2018; hereinafter referred to as 'Patent Document 1') discloses a biometric detector using a heat flux sensor, a vehicle occupant detector, and a technology related to a seat belt not wearing warning system. this is known.

According to this, it is determined whether or not a living body exists at a predetermined position by comparing a predetermined criterion, and when the detection result of the heat flux sensor satisfies the criterion, it is determined that a living body exists at the predetermined position.

또한 대한민국 공개특허 제10-2020-0082263호(2020.07.08.공개; 이하 '특허문헌2'이라 약칭함)에는, 다열 좌석에 적용 가능한 시트벨트 미착용 경고 시스템에 관한 기술이 공지되어 있다.In addition, Korean Patent Publication No. 10-2020-0082263 (published on July 8, 2020; hereinafter referred to as 'Patent Document 2') discloses a technology related to a seat belt not wearing warning system applicable to multi-row seats.

특허문헌 2에 의하면, 착석 여부와 시트벨트 착용 여부에 대한 신호를 해당 좌석의 열 위치에 따라 결정된 주파수 신호로 출력하는 복수의 센서 패키지와, 복수의 센서 패키지에 해당 좌석의 행 위치에 따라 연결되는 복수의 공통 신호선과, 공통 신호선을 경유하는 센서 패키지의 출력신호를 수신하여 카시트별 상태를 판단하는 신호 처리부 및 신호 처리부의 판단결과에 따라 카시트별 상태를 표시하는 출력부를 포함하여, 시외/고속버스와 같은 다열 좌석에 적용시 내부 배선을 간소화하여 와이어/커넥터 등 시스템 구성비용을 줄일 수 있게 된다.According to Patent Literature 2, a plurality of sensor packages outputting signals for whether a seat is occupied and whether a seat belt is worn as a frequency signal determined according to the row position of the corresponding seat, and a plurality of sensor packages connected according to the row position of the corresponding seat Including a plurality of common signal lines and a signal processing unit that determines the state of each car seat by receiving the output signal of the sensor package passing through the common signal line and an output unit that displays the state of each car seat according to the determination result of the signal processing unit, intercity/highway bus When applied to multi-row seats such as , it is possible to reduce system configuration costs such as wires/connectors by simplifying internal wiring.

그러나 상기와 같은 종래의 기술은 특허문헌 1의 경우 열유속 센서를 이용하여 생체를 검지하게 되므로 정확한 생체의 검지는 가능하게 되지만 시스템 구성과 프로세스가 복잡해지는 단점이 있으며, 특허문헌 2의 경우 복수의 센서 패키지가 유선의 공통 신호선을 통해 신호 처리부와 연결되므로 시스템 구성과 프로세스가 복잡할 뿐만 아니라 차량 내부에 탑재된 패널에서만 모니터링 가능하게 되는 사용상의 한계가 있는 등의 단점이 있다.However, in the case of Patent Document 1, the conventional technology as described above uses a heat flux sensor to detect a living body, so it is possible to accurately detect a living body, but there is a disadvantage in that the system configuration and process are complicated, and in the case of Patent Document 2, a plurality of sensors Since the package is connected to the signal processing unit through a wired common signal line, not only the system configuration and process are complicated, but also there are disadvantages such as limitation in use that monitoring is possible only on a panel mounted inside the vehicle.
