摘　　要：设计一种基于GPS定位的老人跌倒提醒系统,该系统以STC12C5A微处理器和ADXL345加速度传感器为核心板,基于SVM阈值法实时检测老人状态,以GPS模块准确定位老人摔倒的位置,当监测出老人跌倒15 s未站起时,通过GSM模块SIM900A电路将相关信息无线远距离传输给监护人。经测试,系统能够在7~10 s内将信息通知到用户,此电路设计的创新点在于系统稳定性好,识别率高,体积小,功耗低,成本低廉。The anti-tumble system for the elderly based on GPS positioning reminder has been designed.Using STC12C5A microprocessor and ADXL345 acceleration sensor as the core board,the system can detect the fall state of the elderly in real time based on the SVM threshold method.At the same time,the GPS module can accurately locate the tumble position of the elderly.When the old person fails to stand up for 15 seconds,through the GSM module SIM900A,the alarm information is transmitted to the guardian wirelessly and remotely.After testing,the system can notify the alarm to the user within 7~10 s.The innovation of this circuit design lies in the system stability,high recognition rate,small volume,low power consumption and low cost.
