The invention discloses an intelligent walking stick based on a NB-IoT (narrow band internet of things) and ultrasonic barrier detection. The intelligent walking stick comprises a walking stick handleand a walking stick body, a sensing switch is mounted on the walking stick handle, a power supply, an ultrasonic barrier detection module, a GPS (global position system) positioning module, a NB-IoTmodule, an MCU (micro-programmed control unit) module and an alarm, the power supply is connected with the sensing switch, the ultrasonic barrier detection module, the GPS positioning module, the NB-IoT module, the MCU module and the alarm, the sensing switch is connected with the ultrasonic barrier detection module, the GPS positioning module, the NB-IoT module, the MCU module and the alarm, theultrasonic barrier detection module is connected with the MCU module, and the MCU module is connected with the GPS positioning module, the NB-IoT module and the alarm. The intelligent walking stick can timely find barriers to remind a user to elude the barriers, and a guardian can know position information of a blind person in real time.
