The smart device 20 includes a GPS positioning module 21, a navigation module 22, and a voice assistance module 23 The voice assistant module 23 is used to convert the GPS positioning module 21, the positioning data of the navigation module 22, the navigation data, the terrain discrimination result signal, and the distance discrimination result signal into speech.

In one embodiment, the walking stick 10 includes a power supply unit 14 for providing power to the terrain detector 11, the distance detector 12, and the processing unit 13.

In one embodiment, the bottom of the walking stick 10 is provided with a wheel body 15 for contacting the ground and turning in multiple directions, thereby enhancing the navigation and guiding functions of the blind.

In one embodiment, the terrain detector 11 is selected from any one of a CCD (Charge Coupled Device) image sensor and a CMOS (Complementary Metal-Oxide Semiconductor) image sensor.

In one embodiment, the distance detector 12 is an acoustic distance sensor, such as an ultrasonic distance sensor.

In one embodiment, the walking stick 10 and the smart device 20 respectively have Bluetooth transmission modules matched with each other for wireless data transmission.

In one embodiment, a part of the terrain detector 11 is arranged on the upper and lower surfaces of the front of the cane 10, the upper side of the cane 10 is bent with a handle 16 and one of the terrain detectors 11 is arranged on the The end of the handle 16 is used to detect the environment and terrain in front of and behind the user, so as to improve the recognition of the environment and terrain and the accuracy of judgment.

In one embodiment, the smart device 20 is a mobile phone.

In one embodiment, the processing unit 13 synchronously combines the surrounding scene data to identify the image detected by the terrain detector 11 for terrain determination.

In one embodiment, the navigation module 22 is a mobile phone navigation APP.

The foregoing is an introduction to the various components of the present invention and their composition methods, and then the use embodiments, features, and benefits of the present invention are introduced as follows:

Please refer to Figures 1 and 3, the user (such as a blind person) can hold the cane 10, first set the desired destination through the navigation module 22, and use the positioning function of the GPS positioning module 21 when walking , And then the voice assistance module 23 can voice instructions and guide users (such as blind people) to reach the predetermined destination, and the distance detector 12 and the terrain detector 11 can detect the terrain and features of the surrounding environment. , Obstacles, and the cane 10 transmits the detected status signal to the smart device 20, and the voice assistant module 23 can simultaneously perform voice prompts and warnings (in case of obstacles or dangerous terrain), thereby assisting the blind in navigation , The effect of guiding the blind.
