The invention relates to the technical field of blind guiding sticks, in particular to an STM32-based intelligent blind guiding stick and a control system thereof.The STM32-based intelligent blind guiding stick comprises a blind guiding stick rod which is divided into an upper section, a middle section and a lower section; a power supply Bat, a loudspeaker SPK, an ultrasonic sensor HC-SR04, a tumble judgment cancel key S2, a self-locking switch S1, an acceleration sensor ADXL345, a positioning module GSP and a short message communication module GSM are mounted on the upper section of the blind guiding stick rod; the ultrasonic ranging circuit is used for detecting the existence of obstacles to perform obstacle avoidance reminding, the water level sensor is used for performing water level detection to realize ponding reminding, the acceleration sensor is combined for performing three-axis acceleration real-time monitoring to realize fall detection, a GPS positioning function can also be realized, and if a user falls and a key is not pressed down within a certain period of time, the user can be reminded. If yes, an emergency help-seeking short message is automatically sent to a preset number, the current position information of the user is attached to the short message, and meanwhile the blind guiding stick can play help-seeking voice to seek help to surrounding people.
本发明涉及导盲杖技术领域,具体的说是一种基于STM32的智能导盲杖及其控制系统,包括导盲杖杆,所述导盲杖杆分为上中下三节,所述导盲杖杆的上节安装有电源Bat、扬声器SPK、超声波传感器HC‑SR04、跌倒判断取消按键S2、自锁开关S1、加速度传感器ADXL345、定位模块GSP及短信通讯模块GSM;本发明通过超声波测距电路检测障碍的存在进行避障提醒,利用水位传感器进行水位检测实现积水提醒,结合加速度传感器进行三轴加速度实时监测实现跌倒检测,而且还可以实现GPS定位功能,若用户跌倒,且按键在一定时间内没有被按下,则会自动发送应急求救短信给预设号码,并在短信中附带用户当前的位置信息,同时,导盲杖将会播放求救语音向周围人求救。
