Ultrasonic waveguide blind warning device

The super-intelligent waveguide blind warning device of the present invention, especially a ring structure which can be worn by a wrist or an ankle, is provided with a vibrator; the ultrasonic waveguide blind warning device applies ultrasonic waves to assist the blind person to sense the effective front. Observe the obstacles in the area and warn them, and use the vibrator to emit vibration strength to warn the distance of the obstacles, which helps prevent blind people from colliding and injury, so as to ensure the safety of the blind.

The new model No. 460666 of the Intellectual Property Office of the Republic of China is a supersonic waveguide blind cap with a speaker or vibrator; the new 460667 patent of the Republic of China Intellectual Property Office is accompanied by a speaker or vibrator. Ultrasonic Waveguide Blind Cane; The Republic of China Intellectual Property Office's new No. 454,837 patent is a supersonic waveguide blind eyeglass with a speaker or vibrator; the Republic of China Intellectual Property Office's new patent No. 460541 is attached. Ultrasonic waveguide blind vest with speaker or vibrator.

As we age, human hearing may degenerate, providing a means of alerting with auditory sensations or vibrations, and may need to reinforce its warning effects.

In view of the above-mentioned conventional problems, the purpose of the present creation is to use the circular structure of the vibrator to utilize the tactile sensation of the wrist or the ankle to reinforce the warning effect of the patented technology on the tactile sensation of the blind.

In view of this, the super-waveguide blind warning device of the present invention, especially an application of ultrasonic waves, assists a blind person to sense an obstacle in an effective sensing area in front, and provides a warning by a vibrator provided in a ring structure on a wrist or an ankle. The super-intelligent waveguide blind warning device that helps prevent collision and fall is its main purpose.

In order to achieve the above object, the supersonic waveguide blind warning device of the present invention is an annular structure, and at least a vibrator is disposed on the annular structure. The ring structure is electrically connected to another ultrasonic sensing device, and the ultrasonic sensing device detects the echo of the wave frequency emitted by the ultrasonic transmitter by the ultrasonic receiver, and calculates the echo time and The vibrator on the ring structure warns the obstacle's azimuth and distance, and the vibrator emits two-stage vibration strength and vibration time length to warn the distance and direction of the obstacle, and detect the obstacles in front. Help prevent blind people from colliding with injuries to ensure the safety of blind people walking.

To achieve the above object, the ultrasonic sensing device couples the vibrator on at least one annular structure.

In order to achieve the above purpose, the control element is a two-stage vibration and vibration time length calculation warning obstacle orientation and distance.

The first picture is the structural diagram of the creation.

The second drawing is a schematic diagram of the state of use of the preferred embodiment of the present invention.

The third figure is a schematic diagram of the warning vibration of the preferred embodiment of the present invention.

The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples.

Please refer to the first figure for the structural diagram of the present creation. The present ultrasonic waveguide blind warning device comprises at least: a ring structure 10, a vibrator 20 and an ultrasonic sensing device 50; wherein the ultrasonic wave The sensing device 50 provides a warning obstacle distance and an azimuth vibration signal to the vibrator 20 on the annular structure 10 after calculating the orientation and distance of the front obstacle; the vibrator 20 is attached to the ring device 10; the vibrator 20, which is electrically connected to the ultrasonic sensing device 50.

When the ultrasonic sensing device 50 calculates the distance of the front obstacle, it provides a warning obstacle distance and an azimuth vibration signal to the vibrator 20 on the annular structure 10, and the vibrator 20 vibrates and is strong or weak by vibration. By distinguishing the distance between the warning obstacles and detecting the proximity of the obstacles in front, it helps to prevent collisions and injuries, so as to ensure the safety of the visually impaired.

As shown in the second figure, it is a schematic diagram of the state of use of the preferred embodiment of the present invention. Among them, the annular structure 10 can be worn on the wrist of a blind person.

As shown in the third figure, it is a schematic diagram of the warning vibration of the preferred embodiment of the present invention. Therein, a static vibration time 94 is arranged between the first vibration time interval 92 and the second vibration time interval 96. When the ultrasonic sensing device 50 calculates the orientation of the obstacle in front, it provides a warning obstacle distance and orientation. The vibration signal is applied to the vibrator 20 on the annular structure 10, and the vibrator 20 vibrates and can distinguish the warning obstacle by comparing the first period of vibration time interval 92 with the length of the second period of vibration time 96. Orientation. When the first segment vibration time interval 92 is greater than the second segment vibration time interval 96, it indicates that the obstacle is biased to the left. When the first segment vibration time interval 92 is smaller than the second segment vibration time interval 96, it indicates that the obstacle is biased to the right. In this way, it helps to prevent collision and injury, so as to ensure the safety of the visually impaired while walking.
