Child Safety Monitoring System

Child Safety Monitoring System
We selected this project because we are very interested in home security and, particularly, the safety of children. With homes becoming larger and more technically advanced, the dangers that children encounter on a daily basis are on the rise. From swimming pools, to stairs, to entertainment systems and home office electronics, hazardous situations are always a threat. We are excited about building a child safety monitoring system in order to minimize these risks. Our device will act as a preventative measure by warning parents of impending danger. This will not only protect children, but it will give parents an extra sense of comfort. Providing parents with this opportunity to better protect their families, our system will define the next generation in child care.
Monitoring System Features:
• Parents designate areas as low, medium, or high risk
• Infrared sensors used for detecting child motion
• Audible alarm sounds when sensors are triggered
• Alarm sounds vary according to risk level
• Minimal delay time to allow for a quick response
• Parents move freely through home without alarms being set off
• Control switches are safely kept from children by a locked box
Performance Requirement
There are two performance requirements that are critical to the quality of the monitoring system. First, it is necessary that the response time is minimal so that the parent is notified immediately of any possible danger. Second, a low percentage of false alarms is vital to the reliability of the product. However, these two factors may interfere with one another. A child will only cross sensors which are below a certain height. On the other hand, an adult will cross all sensor heights, but they may not be triggered simultaneously. This is due to the fact that an adult’s leg will cross a lower sensor before their torso crosses a higher sensor while walking. Since we are using sensors at various heights to determine whether movement is a child or an adult , it may be necessary to hold a signal for a period of time until the subject can be determined. This would increase the delay time, but it would also reduce the number of false alarms. While it is important to reduce the percent error, it is just as necessary to minimize the delay so that the user is alerted promptly. Ideally, we would like to have an accuracy of 96 % and a 500 ms response time. These values may need to be modified once construction begins.
