[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the deepening of population aging, a large number of people will face visual impairment or blindness in the future, and what is more serious is that the rate of increase is also increasing every year. Blind people face serious difficulties in traveling. At present, the construction of blind assistance facilities in China varies greatly from region to region and is not perfect. Most people use guide dogs to travel, which is more feasible in familiar areas, but the training and adaptation period of guide dogs is longer; in addition, the use of canes cannot provide a more comprehensive road condition recognition function and still cannot meet the travel needs of most blind people.

[0004] Blind people face complex road conditions when traveling, such as road construction, missing manhole covers, water accumulation, temporary roadblocks, etc. Existing auxiliary walking devices often use laser sensors, radar sensors, visual sensors, etc. to identify and monitor roadblocks. The invention of application number CN201820349065.0 provides a portable intelligent blind walker, which detects the distance of obstacles through ultrasonic detection. When the distance of the obstacle reaches the set value, the alarm module emits a vibration and sound alarm. However, when detecting close obstacles in the above scheme, the shape of the obstacle cannot be effectively identified, which is prone to false alarms and increases the risk of guiding the blind to walk.

[0005] In addition, existing walking aids usually only assist the wearer himself and cannot provide real-time and effective monitoring for the guardian, so the guardian cannot understand the wearer's status in real time. Utility Model Content

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0031] like Figure 1 As shown, the utility model discloses a wearable walking aid device, which includes a safety integrated helmet 1 and a backpack 2. Figure 2 and Figure 3 As shown, the safety integrated helmet 1 includes a helmet shell 4 and a helmet chin strap 5 arranged on the helmet shell, wherein the two ends of the helmet chin strap 5 are respectively fixedly connected to the two sides of the helmet shell 4, and the wearer fixes the safety integrated helmet through the helmet chin strap when wearing it; a helmet front side boss 9 is provided on the front side of the helmet shell 4, and a first infrared sensor 6, a first visual sensor 7 and an ultrasonic sensor 8 are sequentially provided on the helmet front side boss 9, and a built-in IMU (Inertial Measurement Unit) attitude sensor 10 and an external speaker 11 are respectively provided on both sides of the helmet shell 4, wherein the IMU attitude sensor 10 is a combination of an accelerometer and a gyroscope sensor, which is used to detect acceleration and angular velocity to represent movement and movement intensity, etc., and then detect the real-time posture of the wearer.

[0032] The rear side of the above-mentioned safety integrated helmet is provided with a helmet rear side boss 16, on which the second infrared sensor 13, the second visual sensor 14 and the communication interface 15 are arranged in sequence, and the first infrared sensor, the first visual sensor, the ultrasonic sensor, the second infrared sensor, the second visual sensor, the IMU attitude sensor and the external speaker are all connected to the communication interface through the connecting wire inside the helmet shell. By setting corresponding sensors at the front and back to collect the wearer's surrounding environment in real time, compared with only obtaining the environmental information in front of the wearer's traveling direction, this design of the utility model can achieve a better auxiliary effect.

[0033] Furthermore, a protective sponge 12 is provided inside the helmet shell 4 of the above-mentioned safety integrated helmet to protect the walking safety of the wearer.

[0034] Furthermore, the length of the helmet chin strap 5 is adjustable.

[0035] like Figure 4As shown, the backpack 2 includes a backpack shell and a shoulder strap arranged on one side of the backpack shell. A communication line interface 17 is provided on the backpack shell. A processor is fixedly installed inside the backpack shell. The processor is electrically connected to the communication line interface 17. The communication line interface 17 is connected to the communication interface arranged on the helmet shell through a communication line 3. That is, multiple sensors on the safety integrated helmet are connected to the processor through the communication line, and a variety of information collected in real time is transmitted to the processor for processing. At the same time, the processor is connected to an external speaker through the communication line, and the result processed by the processor is transmitted to the external speaker through the communication line, so as to assist walking through sound reminders.

[0036] In order to ensure the reliability of data transmission, the above device adopts a wired connection. Under the condition of ensuring stable network transmission, wireless data transmission can also be adopted.

[0037] As another implementation, in addition to guiding the wearer to walk by voice broadcasting navigation results, other effective methods can be used to instruct the wearer to walk, such as playing buzzer sounds at different times through an external speaker to remind the wearer of the current road conditions, thereby assisting walking.

[0038] Furthermore, a large-capacity micro mobile power source is also provided inside the backpack, and the micro mobile power source is electrically connected to the processor, a plurality of sensors, and an external speaker to supply power to the entire device.

[0039] Furthermore, the backpack is also provided with a GPS locator, which is electrically connected to the processor and is used to transmit real-time positioning information to the processor.

[0040] Specifically, the above-mentioned visual sensor, infrared sensor, and ultrasonic sensor transmit the real-time collected information to the processor, and the processor processes the received real-time collected information through an algorithm, including identifying the shape and size of obstacles based on the images collected by the visual sensor, identifying the location and risk factor of obstacles based on the temperature data collected by the infrared sensor, and identifying the distance of obstacles based on the data collected by the ultrasonic sensor. After processing, the wearer's walkable area in the path is obtained, the wearer's walkable route is calibrated, and the route is converted into voice information, which is used to remind the wearer in the form of voice broadcast through an external speaker to provide guidance for the next step of walking; at the same time, the processor The device processes the received GPS positioning information to obtain the wearer's position data. In addition, the processor processes the received IMU posture data. In the utility model, a quaternion solution method is adopted to convert the acquired IMU posture data into the human body angle through matrix transformation and integration. The deviation angle is judged according to the preset correct wearing posture, such as the normal posture in the positive direction of the Z axis, combined with the actual human body angle obtained based on the actual IMU posture data. If the deviation angle exceeds the preset value, the wearer's current posture is judged to be an abnormal posture, which means that the wearer may face a fall and a warning needs to be issued.

[0041] Furthermore, the processor includes a communication unit, and the processor communicates with the remote client through the communication unit. Specifically, the processor transmits the real-time information collected by the multiple sensors to the remote client through the communication unit. The remote client includes a display screen, which displays the real-time status information of the wearer (including images collected by visual sensors, obstacle temperatures collected by infrared sensors, obstacles collected by ultrasonic sensors, and the wearer's walkable area, etc.), that is, the remote client performs a visual display of the real-time information collection; at the same time, the processor transmits the wearer's real-time position data and real-time posture data to the remote client, and issues an alarm of the wearer's current status through the remote client, such as when the wearer's current posture is determined to be an abnormal posture, an alarm is issued to facilitate the guardian to monitor.

[0042] The above remote client is used as a visualization platform to receive data information transmitted by the communication unit and perform digital twin visualization on the received data information. Through the digital twin visualization platform, the received data is visualized as a digital twin to display the wearer's position and posture information, etc., and the platform is published and shared to facilitate the monitor to observe the wearer's position and posture information in real time. The positioning data calls the interface of the commercial software, which is used for blind positioning and is displayed in real time on the map.

[0043] The wearable walking aid proposed by the utility model wears the hardware device on the body in the form of a backpack, wears a safety integrated helmet on the head, arranges multiple sensors on the top of the helmet, connects the sensors and the processor by wire, uses multiple sensors to collect the surrounding environment in real time, ensures the accuracy of the collected data and the analyzed data, and thus ensures the accuracy of the path; the power supply, processor, etc. are arranged in the backpack for easy carrying.

[0044] The wearable walking aid device proposed by the utility model collects the wearer's surrounding environment through visual sensors, and the processor processes the real-time collected video stream to identify obstacles, real-time road conditions, feasible areas, and traffic light signs in the wearer's walking path, and uses the data collected by infrared sensors and ultrasonic sensors for auxiliary adjustments to obtain an accurate and feasible route for the wearer to walk, guide the wearer to walk in the form of voice broadcasts, and visualize the wearer's position and posture information in real time. The guardian can observe the wearer's position and posture information in real time on the remote client and pay attention to the wearer's travel safety.

[0045] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model.
