And the starting key 4 is round and is arranged at the position close to the front part of the top surface of the handle 1, and the starting key 4 adopts a square shape and is used as a main switch for starting and closing the intelligent tactile stick.

A camera 5, camera 5 is located handle 1 front end for shoot the picture in the place ahead that the user marchs, this picture can supply microprocessor to carry out image recognition on the one hand, and on the other hand can upload cloud ware or local storage module, supplies guardian to know user's trip information.

The sensors are installed at all positions of the handle 1 according to requirements, and output interfaces of the sensors are connected with the microprocessor. The system comprises a distance measuring sensor, an infrared sensor, an acceleration sensor, a heart rate sensor and the like, wherein the distance measuring sensor is used for distinguishing the distance between a user and a peripheral obstacle so as to give an alarm to the user in time and avoid collision; the infrared sensor is used for the user to know the approaching information of surrounding animals, human beings, high-temperature articles and low-temperature articles in time, so that the user can avoid danger in time; the acceleration sensor is used for detecting the travelling acceleration of the handle 1, and particularly when the handle 1 falls off, the handle 1 is bound on the wrist of a user by the bracelet 3, so that the falling off of the user can be judged, and the injury condition of the user can be known in time; the heart rate sensor is used for detecting the physical sign of a user.

And the positioning module can adopt various common navigation components such as Beidou navigation or GPS navigation, and the output interface of the positioning module is connected with the microprocessor and used for knowing the position of a user in real time.

And the output interface of the recording module is connected with the microprocessor, and the input interface is connected with the Bluetooth microphone through the Bluetooth module. When in use, the user can input control commands to the microprocessor in a voice mode.

And the navigation module is interactively connected with the microprocessor, gives a navigation path according to the position information analyzed by the microprocessor and the target information input by voice, and corrects the navigation path in time when the user deviates from a preset route according to the advancing position of the user.

And the input interface of the voice module is connected with the microprocessor, and the output interface of the voice control module is connected with a Bluetooth module which is wirelessly connected with the Bluetooth earphone. When the Bluetooth headset is used, the peripheral environment information, the navigation information, the early warning information and the like are broadcasted to the Bluetooth headset worn by a user according to the control information of the microprocessor.

And the input interface of the contact control module is connected with the microprocessor, and the output interface of the contact control module is connected with a Braille display module 17 positioned at the top of the handle 1. The Braille display module comprises a plurality of display units which are arranged in an array and embedded at the top of the handle 1, the display units comprise a circular sleeve-shaped shell 7, contact pins 8, a moving magnet 9, a fixed magnet 10 and an alarm switch 11 are sequentially arranged in the shell 7 from top to bottom, and the contact pins 8 are sleeved with a baffle ring 12 fixed on the inner wall of the shell 7 in a sliding manner; the moving magnet 9 is a permanent magnet blocked below the baffle ring 12, and an upper spring 13 sleeved outside the contact pin 8 is connected between the moving magnet 9 and the baffle ring 12 in a propping manner; the fixed magnet 10 is an electromagnet connected with the contact control module, and a lower spring 14 which is sleeved outside the alarm switch 11 and has a blank part is connected below the fixed magnet 10 in an abutting mode; the alarm switch 11 is a microswitch connected to the microprocessor.
