儿童校车安全监管系统Safety Supervision System of School Bus for Children摘 要青少年的安全健康是备受国家和社会关注的话题，尤其是儿童校车的安全监管问题。为此，本文设计了一个儿童校车安全监管系统，其控制核心为STC89C52 单片机，主要功能模块包括数据显示模块、语音播报模块、射频读写模块、速度检测模块、超速警示及远程通报、门禁控制模块等。系统可检测并显示车速，若车速超过预设值将启动蜂鸣器警示，并由无线模块将超速信息进行远程通报。学生乘车时需先刷卡读取信息，到站后需刷卡下车，此时语音将提示学生下车。当系统识别已乘车学生尚未下车时，校车车门将无法关闭。此外，系统可对乘车卡进行清除绑定或者注册绑定，并通过按键设置车速限值。本系统经济实用、操作简单，可为当前儿童校车的安全运行和监管提供有力的辅助作用，一定程度上保证乘车儿童的安全。关键词：安全；GSM；RC522；WT588-I-AbstractThe safety and health of adolescents is a topic of great concern to the state and society, especially the safety supervision of school buses for children. Therefore, this paper designs a safety supervision system for children's school bus, whose control core is STC89C52 single chip computer. The main function modules include data display module, voice broadcast module, radio frequency reading and writing module, speed detection module, overspeed warning and remote notification, access control module, etc. The system can detect and display the speed. If the speed exceeds the preset value, the buzzer warning will be activated, and the wireless module will communicate the speeding information remotely. Students should first swipe their cards to record information, and then confirm their arrival by swiping their cards. At this time, they will be prompted to get off by voice. The school bus door will not be closed when the system recognizes that the students who have already taken the bus have not yet got off. In addition, the system can clear t...
