The utility model discloses an intelligent blind guiding walking stick which comprises a stick rod and a stick handle. The inside of the stick rod is of a hollow structure. A single chip microcomputer control circuit, an ultrasonic transmitting and receiving circuit, a warning circuit, a temperature and humidity collecting circuit, a wireless transmission circuit and a power circuit are arranged inside the stick rod, wherein the power circuit supplies electricity to the single chip microcomputer control circuit, the ultrasonic transmitting and receiving circuit, the warning circuit, the temperature and humidity collecting circuit and the wireless transmission circuit. The single chip microcomputer control circuit is an embedded system which is composed of a microprocessor chip and a peripheral circuit of the microprocessor chip. The ultrasonic transmitting and receiving circuit comprises an ultrasonic sensor and is connected with a single chip microcomputer chip through a one-bit two-way single-bus interface. Compared with the prior art, the intelligent blind guiding walking stick has the following advantages that the ultrasonic transmitting and receiving circuit is arranged inside the walking stick, when the ultrasonic sensor detects an obstacle around a blind guiding walking stick user, the single chip microcomputer control circuit issues an instruction, a loudspeaker gives out an alarm, the blind can be reminded to bypass the obstacle, and thus the obstacle can be avoided.
