Intelligent guide man-machine interaction device

Abstract

The invention discloses an intelligent guide man-machine interaction device. The device comprises a master controller, wherein a 16-bit microprocessor is adopted by the master controller to control that a main circuit is connected with a wireless module through a 232 serial port; the master controller is connected with an earphone microphone through an audio input port, connected with an earphoneheadphone through an audio output port, connected with a guide robot through a rope induction tension detection device and connected with a vibration inductor by a drive; and an interruption input port of the master controller is connected with braille touch keys. The device has the advantages of voice recognition and broadcasting, wireless command transmission, rope tension induction, vibration inductor output and the like, can ensure a proper safety driving distance with the guide robot by realizing man-machine interaction through the voice induction and the vibration induction, increases the use safety and interaction convenience of a handhold device, effectively solves the problem of man-machine interaction of the intelligent guide robot under outdoor environment and has high application value.

Description

technical field [0001] The invention relates to a blind-guiding device, in particular to an intelligent blind-guiding man-machine interaction device which is convenient to use, reliable and safe, and has a wide range of applications. Background technique [0002] With the development of modern science and technology, the research on blind guide technology at home and abroad has reached a certain level, and the human-computer interaction links of blind guide devices also have their own characteristics, such as: electronic guide sticks, equipped with ultrasonic sensors, It can sense obstacles at the height of the face in front and notify the user through the vibration handle; blind guide gloves are equipped with several ultrasonic sensors on ordinary gloves to achieve obstacle avoidance function; robot guide blind, as another specific field of robot application , can give full play to the actual mobility and flexibility of the robot, and involves many technologies such as comm...

Problems solved by technology

[0003] Nowadays, infrared remote control, voice recognition and other related devices have appeared, but the human-computer interaction devices used in the field of blind guide robots still have some shortcomings in terms of functionality, such as: the infrared remote control uses the infrared emission unit to control the user's The instructions are transmitted to the electrical equipment wirelessly according to a certain encoding format. When the remote control has many function keys, the user can only use the traditional cumbersome control mode of memory plus key combination, which is very inconvenient to use.

Traditional voice recognition devices have relatively high requirements on the surrounding environment. During the use of outdoor robots, the recognition effect is greatly affected by the noise environment. In the process of guiding the blind, the synchronization of human-computer interaction is poor
