Abstract:To deal with the problem that the death accidents of young child being left on school bus alone are occurred frequently in summer， the preventive of young child detection， accident alarm for school bus was proposed. The infrared thermopile array sensors were used to detect whether the young child was left on school bus or not by measuring every inner pixel temperature of school bus and comparing those temperatures with the inner ambient temperature of school bus. When the young child was left on school bus alone， the controller would read the location information of school bus from the GPS modular and sent the short alarm message that contained the longitude and latitude of school bus to the designated phone by GSM modular. The alarm APP would be activated when the short alarm message was received and the phone would vibrate and play alarm music to warn the owner. The geographical position of school bus could be displayed in the electronic map of the phone， which could provide the convenience for rescue. After testing， the young child being left on school bus detection success rate was 94% and the rate of sending warning message， driving the APP alarm and opening the electronic map and positioning were 100% after the child being detected correctly. The left young child detection device could be amounted in school bus and the alarm APP could be installed in the phone of young children5 parents and teachers， which could send out alarm signal proactively when the young child was left on school bus alone and enhance the safety of children riding.
