detailed description

In order to better understand the present invention, the present invention will be further explained below in conjunction with the specific embodiments.

Example 1

The blind walker device of the present embodiment is mainly used by a blind person and a low vision person, and is integrated into a small module and worn on the chest. According to FIG. 1 , a detection system, an analysis system, an introduction system, a voice system, a transmission system, a memory system, and a positioning system are included, wherein the detection system is composed of an image recognition module, a voice recognition module, and a temperature sensing module, and the image recognition module uses a laser. Radar technology detects the contour and moving speed of surrounding objects, uses electronic scanning technology to detect the name and number information of the place, the voice recognition module uses sound recognition technology to detect the sound, and the temperature sensing module uses infrared technology to detect the temperature. The analysis system uses bio-simulation analysis technology to synthesize the detected signals into image signals, and judges the specific state of the detected objects, such as humans or animals or other specific objects, and can also determine traffic lights, office numbers, shopping malls, airports. And the name of the station, the sign of the bathroom, the opening and closing state of the elevator, and the ability to determine the distance between the target and the user and the appropriate passage time range, analyze the meaning of the surrounding sound, and analyze the weather. The introduction system uses a signal conversion technology to inform the user of the detection signal of the detection system in an audio form, such as distance from the target, obstacles during the travel, etc., or inform the user of the analysis result of the analysis system, such as travel time. And evasive methods, etc.

The following is a specific use example. The blind person A can use the device to observe an object in the horizontal direction of 0 to 180 degrees and a vertical direction of 0 to 180 degrees by the image recognition module. Before going out, A sets the destination to the 818 room of an office building through the voice recognition module of the detection system. The analysis system accepts the signal of the detection system and connects the network through the positioning system to set the walking path. The voice system tells A that the temperature of the day is 18-25 °C, there is light rain, and it is necessary to prepare rain gear. A comes out of the home of the residential building. The equipment recognizes the nearby environment through the image recognition module of the detection system. The signal is transmitted to the user through the introduction system using the signal conversion technology to inform the user of the position of the stairs in an audio form, and the detection signal is analyzed through the analysis system. Later, the introduction system uses signal conversion technology to introduce the analysis results into the voice system to guide them into the stairs and safely walk out of the residential building. According to the above work mode, A prompts down to the bus station at the step by step of the device. When the bus that it needs arrives at the station, the device prompts A to multiply. car. After taking the bus for 3 stops, the device prompts A to get off and change to the subway, and the reminder is raining, and an umbrella is needed. A in the voice navigation prompts of the equipment to the entrance of the subway station, a total of 3 turns, encountered a traffic signal, the equipment is prompted one by one, the equipment promptly prompts to take the escalator, queue up to buy tickets at the ticket office, and then pass the gate Before entering the subway, before entering the subway, A enters the toilet and goes to the toilet under the guidance of the equipment. After exiting the subway, the equipment guides them to enter the office building, finds and takes the elevator to the 8th floor. The equipment recognizes the word “818” on the door through the image recognition function, and guides A to enter. A uses the device call function to know that you need to take a train to go to a business trip, at the device prompt, A taxi to the train station, with the help of the equipment to buy tickets and pit stops. In the above process, the transmission system uses real-time propagation technology to save the picture and sound signals to the local storage system of the memory system and remote terminal devices such as computers, mobile phones and the cloud.
