摘要
笔者以STC89C52单片机为基础实现老人防跌倒系统硬件电路设计。该设计主要由ADXL345三轴数字加速度传感器、STC89C52主控芯片、GPS模块、GSM模块和蜂鸣器报警电路等组成。主控芯片对传感器传输的数据执行是否跌倒检测算法,若符合跌倒发生条件,蜂鸣器会报警并以短信方式发送定位信息,使因跌倒而损伤的老年人迅速得到相关医疗服务,从而减少损害,保障老年人的生命安全。
Based on STC89C52 single-chip computer,the author realizes the hardware circuit design of the anti-fall system for the elderly.The design is mainly composed of ADXL345 three-axis digital acceleration sensor,STC89C52 main control chip,GPS module,GSM module and buzzer alarm circuit.If the condition of falling occurs,buzzer will alarm and send location information by short message,so that the elderly injured by falling can get related medical services quickly,so as to reduce the damage and ensure the life safety of the elderly.
