Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the utility model pertains.

As shown in fig. 1, the embodiment provides a blind person navigation obstacle avoidance backpack, which includes a backpack body 100, a backpack belt is disposed on a back portion of the backpack body 100, and the backpack further includes a control main board 110, a distance detector, a vibrator, a display panel 400 and an action switch, wherein the control main board 110 is fixedly disposed on the backpack body 100; the distance detector is fixedly arranged on the back strap and faces the front, the distance L between a user and a front obstacle or a pedestrian is obtained through the distance detector, and the distance L is transmitted to the control main board 110; the vibrator is electrified and vibrated when the distance L is smaller than a set value L0 to remind a user; l0 is 3-5 m. This embodiment is preferably 4 m. The display panel 400 is electrically connected to the control main board 110 to display text information, where the text information includes information indicating that the user does not have normal vision or prompting passerby to avoid; the operation switch is disposed at a connection portion between the shoulder strap and the backpack body 100, and the backpack body 100 is turned on to connect the circuit to operate when being carried by a user. The distance detector who sets up can perceive barrier or pedestrian in the place ahead in advance, and the user can receive the vibration suggestion that the vibrator sent before colliding barrier or pedestrian, and then can assist the user to bypass barrier or pedestrian, has improved the security that the user who has visual disorder went on a journey.

In order to supply power to the above-mentioned devices, a battery is further provided in the backpack body 100. The storage battery is electrically connected with the electronic device. The action switch is arranged to be able to turn on and off the electrical connection between the battery and the electronic device.

The vibrator is a vibration motor 500, and a first fixing bag 210 for fixing the vibration motor 500 is arranged on the back strap. When the backpack body 100 is worn, the straps are tightly attached to the user, so that the user can more obviously receive the vibration information of the vibration motor 500.

The braces includes the left side area body 300 and the right side area body 200, the distance detector set up in on the left side area body 300, the distance detector is ultrasonic sensor, correspond on the left side area body 300 ultrasonic sensor is provided with the fixed bag 310 of second, the skin of the fixed bag 310 of second corresponds two probes of ultrasonic sensor are provided with two holes of stepping down. The intelligent control system also comprises a buzzer, and the buzzer is connected with the control main board 110. The buzzer can also assist in sounding, and the reminding effect is improved.

The display panel 400 is an LED matrix board. When in use, the LED lamp can be used as a flashing lamp and a warning lamp by intermittently lighting.

When the blind person goes out, the blind person needs to walk a familiar route, and other people are required to take the way to a strange place. In order to facilitate the trip of the blind, the embodiment adds a navigation function, and a satellite positioning component is arranged on the backpack body 100, and is connected with the control main board 110. Because the blind person is difficult to input characters, the voice recognition chip is arranged on the control main board 110, and the microphone for receiving the voice is arranged on the back strap. When the blind people go out, the blind people only need to speak out the destination, the route is planned by the control main board and then played through the loudspeaker, and the blind people select the proper route through voice. And playing the real-time road conditions through a loudspeaker after the selection is finished.

In order to more conveniently navigate the blind, the step number is used for representing the remaining distance in the control main board, before the blind uses the blind, the average stride of the blind is input into the control main board, and the control main board is convenient to convert the traditional meter number into the step number.

The present embodiment is further provided with a remote controller matched with the control main board 110. When the backpack is used, the blind enters a backpack searching mode by pressing a No. 1 key on a remote control, a buzzer of the backpack sounds, and the buzzer stops sounding after the backpack is found. After the user carries the backpack on the back, the straps are stressed to trigger the action switch, so that the whole equipment is electrified to enter a working state. When the blind person moves forward and an obstacle appears 5 meters in the front direction, the ultrasonic sensor sends a signal to the loudspeaker to prompt that the obstacle exists in the front. When the obstacle is close to 3 meters, the infrared sensor can send a signal for judging whether the obstacle is a person or an object to the loudspeaker, and meanwhile, the vibration motor can vibrate rapidly. The blind should wait standing or change direction to move. When the blind person reaches the destination, the backpack is taken off, the action switch is switched off, each sensor stops working, and the main board 110 is controlled to be in a standby state. The top of the backpack is provided with a solar charging panel which is communicated with the internal storage battery. When the outdoor traveling, the solar charging device can be charged through sunlight.
