Development of comprehensive unattended child warning and feedback system in vehicle

Abstract

Abstract. The cases of children being trapped and suffocated in unattended vehicle keep increasing even though the awareness campaign on the safety of children in non-moving vehicle were carried out by government. Various methods were introduced by researchers to overcome this issue but yet to be effective. Among them were the usage of capacitive sensor, microwave sensor, pressure sensor and image sensor where most of the techniques or systems were applied on the child's seat to detect the presence of baby or infant. Thus, this research is carried out to provide a comprehensive and effective detection system to detect the presence of children including infant in unattended vehicle by using the combination of human physiological signals (voice and body odor) detectors with the temperature and motion sensors. Here, once the proposed system recognizes any signals that generated from voice, odor, motion and temperature detectors in vehicle's cabin, the system then will provide effective feedback system by sending short message to the parents first. If no response received in the specified allocation time, the system then will activate the vehicle's horn system. Finally, the system will lower down the vehicle's window to release the toxic gas and reduce the cabin temperature. The system is in prototyping stage where every design component was evaluated individually. Besides, the overall system was successfully tested where the detection and feedback system follow the instruction given by the microcontroller.

“…T2DM patients are very susceptible to tuberculosis infection because of weak immune system and have 2-3 times more risk for tuberculosis compared to people without T2DM [5].…”

Child Presence Detection System and Technologies

“…Based on Figure 3(a), a sound sensor is added to the system to recognize the crying baby voice. Moreover, Sulaiman et al (2017) proposed a system to detect the presence of children including infants in an unmanned vehicle. Figure 3(b) describes two major components of the system consisting of detection and feedback systems.…”

Innovative complete solution for health safety of children unintentionally forgotten in a car: a smart Arduino‐based system with user app for remote control

“…Fig. 7 shows the prototype version and the block diagram of the system referred to in [12]. It is designed for detecting the child's presence in a vehicle on the basis of different parameters as movement, temperature, voice and odour, eventually sending a message to the driver, activating horn sound and lowering the car windows.…”

“…The system reported in [12] allows reducing the false alarms probability because the detection is based on several parameters: movement, voice, odour and temperature. The main feature of this system is the e-Nose (electronic Nose) technology, able to recognise the child's scent into the vehicle.…”
