SECURE CHILD CAR SEAT HARNESS WITH SMART MONITORING AND CRASH DETECTING TECHNOLOGY

Abstract

Abstract A new children car seat harness that integrates smart monitoring and collision warning technologies to improve child safety in automobiles. Traditional car seats, although dependable, do not provide real-time data on harness fit, kid posture, and ambient factors, 5 which are critical for successful protection. The system uses loT sensors to continually monitor harness tension, kid posture, temperature, and vehicle movement. If the harness is not correctly adjusted or the kid moves into a dangerous position, alarms are delivered to the caregiver's smartphone, allowing fast remedial action. FUrthermore, the system's aq;ident detection feature detects collisions and automatically alerts emergency contacts, improving 10 · reaction time in critical circumstances. By merging loT and smart sensing technologies, this solution tackles critical constraints in traditional kid car seats, resulting in a safer and more responsive environment for children. The syste111 demonstrates the possibility for integrating modern technology into ordinary safety gear, bridging the gap between passive protection and proactive safety monitoring.

Specification

Field oflnvention
Child safety in cars has come a long way due to new loT and sensor technologies that
combine child rider protection with cutting edge loT technologies. This system is a part of the
larger Internet of Things (loT) and safety automation w<;>rld. Its main goal is to maintain
5 children safe in vehicles. This technology fills a very important gap in child transport safety
by combining real-time tracking and crash recognition. Current systems don't offer this kind
of instant feedback and reaction. loT monitors in this harness system let the system
constantly check the fit of the harness, the child's position, and the temperature of the ·
environment. This turns passive child car seats into active safety devices. This new idea
10 combines safety features for cars, smart tech, and healthcare that uses the loT. It shows a
multidisciplinary approach to safety issues. This system fits in with new trends in
personalised safety solutions because it focusses on protecting vulnerable people. It uses loT
to improve accident reaction and continuous tracking. Using these kinds of technologies
illustrates that people in the field are dedicated to making transportation better and smarter
15 for children.
Background oflnvention
The creation of a smart kid car seat harness with accident detection and monitoring
technology stems from the growing need for improved child passenger safety measures.
Despite continued advances in automobile safety, motor vehicle accidents (MVCs) continue
5 to be the greatest cause of death and injury among children. Traditional child restraint
systems (CRS) have progressed at a slower rate than adult safeguards, leaving a gap that new
technologies attempt to close. For example, the EU's SAFESEA T initiative seeks to improve
car seat safety by using military-grade materials, innovative sensors, and ergonomic designs
that are especially intended to protect babies in high-impact crashes, including both frontal
10 and side impacts. Modern car seat technologies use advances such as artificial intelligence
(AI) and radar-based monitoring to identify a child's presence and physical state, even while
they are concealed (e.g., beneath blankets). Such technology may trigger automatic alarms or
emergency measures to avoid injury or death, addressing concerns about heatstroke and other
post-crash dangers. The incorporation of real-time monitoring technologies is projected to
15 encourage improved safety standards and help to lowering the I ,3 million MVC-related
injuries affecting children globally each year

Summary of Invention
The smart kid car seat harness with monitoring and. collisi~n det~ction te~hnoiogy .. is an
innovative solution that improves child safety while driving. This system uses many sensors,
communication modules, and a sophisticated microprocessor to track different elements of
5 the child's safety in real time, such as.harness fit, posture, ambient conditions, and probable
crash occurrences. The main purpose is to keep the yoimgster secure, comfortable, and
protected from hazards such as poor harness adjustment, extreme heat, and possible
accidents. The system operates using a mix of sensors and communication technologies.
Temperature and humidity sensors are important because they monitor the interior
10 environment of the vehicle and help to avoid heatstroke and hypothermia. The accelerometer
and gyroscope sensors detect abrupt changes in the car's motion, whiCh may indicate an
accident. In such instances, the system may transmit timely notifications to emergency
contacts or responders via integrated communication modules. The pressure sensors in the
harness also offer real-time input on the tightness and placement of the seat straps, ensuring
15 that they are properly adjusted to keep the youngster safe.
To analyse and coordinate sensor data, the system uses a microcontroller, such as the
Raspberry Pi Zero W. The microcontroller serves as the core unit, collecting information
from all linked sensors, processing it, and initiating actions such as sending alarms or altering
the car's surroundings. It communicates with mobile apps via Wi-Fi or Bluetooth, enabling
NI- 20 parents to remotely monitor their child's status. For example, if the temperature inside the
E vehicle exceeds a specific level, the system sends an alert to the parent's phone, warning them
~ of the danger of heatstroke. Furthermore, the system includes kid presence detection using --::1' infrared or radar sensors, which may notify carers if the youngster stays in the seat after the
~ vehicle is switched off. This function is critical for averting mishaps involving children left
CIO o 25 behind in hot automobiles, lowering the chance of heat-related injuries. Health monitoring
functions, such as heart rate and respiration monitoring, may also relate to biometric sensors
like the· MAX30 I 00, delivering real-time health data to the caregiver's smartphone app. In the
case of an emergency, such as an accident, the system's collision detection technology, driven
by the accelerometer, automatically notifies emergency contacts and medical services,
allowing them to react more quickly.
The communication module, which may incorporate Bluetooth (for short-range
communication) or GSM (for cellular connection in the event of long-range communication
demands), is critical to guaranteeing the sy~tem's connectivity. Bluetooth enables real-time
communication between the child's car seat and the parent's smartphone, whilst GSM
modules may send SMS warnings when there is no direct Bluetooth connection available,
providing continuous monitoring. To guarantee that the system works even in distant regions
5 where it may be used for long-distance, low-power communication. This would be especially
useful in rural regions or places where other communication channels are difficult to get. The
smart kid car seat system works by continuously moilitoring and responding automatically.
Once the se':lsors gather data, the microcontroller analyses it and performs predetermined
actions. For example, if the kid is not correctly strapped in the seat, the pressure sensor will
10 warn the system and send a signal to the caregiver's smartphone.
Similarly, in the case of an accident, the system's accelerometer senses the impact and
delivers an emergency alarm. Furthermore, environmental sensors guarantee that the
youngster is comfortable and not at danger from harmful circurnstances inside the car, adding
an extra layer of protection. In conclusion, the smart kid car seat harness with monitoring and
15 collision detection technology guarantees that children are not only securely strapped in their
car seals, but also continually monitored for environmental and health risks. This approach
improves safety, provides parents with peace of mind, and allows for speedier emergency
response in critical circumstances by combining contemporary sensors and commwlication
technology into a coherent system.
