[0051] Working process:

[0052] The utility model is a complete set of blind auxiliary wearable equipment, which can simulate the use scenarios in the daily life of the blind to describe the overall use process. For example: the use scenario when the blind wearer uses a vertical lift. First, when the blind person steps out of the use scenario, the neck infrared rangefinder 1 can detect the distance between the elevator door and the wearer. After the neck infrared rangefinder 1 identifies the obstacle, it sends the information to the information processor 34 through the Bluetooth module. The wearer is informed by the buzzer 53 that there is an obstacle in front, and then the information processor 34 feeds back to the chest video recognition recorder 2 to identify the obstacle in front. The video recognition recorder 2 identifies the object within the specified distance in front. After the recognition is completed, it will be sent to the information processor 34 through the Bluetooth module, and the information processor 34 obtains After receiving the information, the analysis result is notified to the wearer through the micro-speaker 44. At this time, the wearer receives the information and learns that there is a vertical elevator door in front. Then the wearer detects the specific operation button position by holding the close-fitting detection cover 5. The hand-held close-fitting detection cover 5 feeds back the detection information to the information processor 34, and after identification by the information processor 34, it informs the wearer. The blind person can obtain the button position information and other real-time information of the elevator at this time. After completion, the elevator riding work can be completed through auxiliary voice. If a model other than the collected data is encountered, when the voice broadcast by the micro-speaker 44 does not match the actual situation, the specific information can be adjusted through the hand Braille auxiliary input device 4, and then the newly collected information is uploaded through the information processor 34 and the Bluetooth module to improve the database system.
