Alternatively, fig. 2 is a schematic diagram of body key positions in the application embodiment, and as shown in fig. 2, the at least two body key positions (indicated by black dots in the figure) include at least two of a shoulder position, an arm position, a wrist position, a palm position, a chest position, an abdomen position, a waist position, a back position, a hip position, a thigh position, and a lower leg position.

Specifically, according to the specific form of the walking assistant suit for the blind, corresponding key positions of the body can be set, for example, table 1 below is the corresponding relationship between the specific form of the walking assistant suit for the blind and the key positions of the body provided with the sensors and the prompters:

the sensor is used for acquiring and processing environmental data of the surrounding environment of the at least two body key positions and sending the acquired environmental data to the controller;

optionally, the sensor may be an ultrasonic sensor or other sensor capable of measuring distance, and the environmental data measured by the sensor may be distance data between the blind user and surrounding objects.

The ultrasonic wave is a frequency and is higher than 20000Hz (Hertz) sound wave, and the directionality is good, and the directive property is than stronger, and the reflective capacity is strong, uses ultrasonic sensor to range a distance and can easily obtain more concentrated sonic energy, can better discernment barrier position, and is small in addition, and the real-time strong, the precision is high, and energy consumption is low, easily carries, and is with low costs, changes the popularization.

The controller is used for determining a target body key position with an obstacle from the at least two body key positions according to the environment data, and sending a prompt instruction to a prompt set in the target body key position.

After receiving the environmental data sent by the sensor, the controller performs data processing according to the environmental data to determine the distance between the blind user and surrounding obstacles, determine the key position of the target body close to the obstacles, and send a prompt instruction to a prompt set at the position.

For example, if the sensor determines that the shoulder position of the blind user is close to an obstacle, such as a billboard disposed on the roadside, the controller sends a prompt instruction to the sensor disposed at the shoulder position. Compared with the prior art, the blind person barrier warning device has the advantages that the barrier on the ground can be reminded, the barrier in the air can be reminded, and accordingly the safety of the blind person user in the all-round mode in the traveling process is protected.

The prompter is used for prompting the blind persons for obstacles according to the prompting instruction.

After the prompter receives the prompt instruction sent by the controller, the barrier prompting is carried out on the blind user by outputting prompt information, so that the blind user is prevented from touching the barrier, and the traveling safety is guaranteed.

The application provides a blind person's auxiliary clothes of going on a journey, through setting up the sensor perception blind person user's surrounding environment situation at a plurality of health key positions of user to carry out the barrier through setting up the prompting device at the target health key position that has the barrier and remind to the user, thereby can greatly reduced blind person user touch the probability of barrier, from all-round, multi-angle guarantee blind person user's trip safety.

In some embodiments, the distance between the set position of the sensor and the set position of the prompter corresponding to the sensor is smaller than a first preset threshold, and the first preset threshold may be, for example, 5cm (centimeter), so that the prompter can accurately prompt the target body key position where the obstacle exists.

In some embodiments, the controller is specifically configured to determine whether an obstacle exists within a preset distance range of the body key position according to the environment data, determine that the body key position is the target body key position if the obstacle exists, and send a prompt instruction to a prompt set in the target body key position.

Specifically, fig. 3 is a working schematic diagram of each structure in the walking assistant suit for the blind, as shown in fig. 3, after receiving environmental data sent by a sensor, a controller determines whether an obstacle exists in a preset distance range of a key position of a body corresponding to the sensor, for example, determines whether an obstacle exists in a range of 2m (meters) away from the key position of the body, and if not, determines that a surrounding range of the key position of the body is a safety range; if the body key position exists, the controller determines that the surrounding range of the body key position has potential safety hazard, so that a prompting instruction can be sent to a prompting device at the corresponding position.

Specifically, the indicator may be an element capable of outputting an audio signal, such as a speaker or a buzzer, an element capable of outputting a vibration signal, such as a vibrator, or a combination of both elements.

After receiving a prompt instruction sent by the controller, the prompter reminds the blind user by sending out a sound signal and/or a vibration signal.

the prompter is specifically used for performing obstacle reminding on the blind according to a first reminding strategy and a second reminding strategy according to the first reminding instruction; and the sound reminding volume corresponding to the first reminding strategy is larger than the sound reminding volume corresponding to the second reminding strategy, and/or the vibration reminding frequency corresponding to the first reminding strategy is larger than the vibration reminding frequency corresponding to the second reminding strategy.

Specifically, the controller can send different prompting instructions to the prompter according to different distances between the key position of the target body and the barrier, so that the prompter can remind blind users of different degrees and grades.

For example, table 2 below is a specific example for each case:

as shown in table 2 above, assuming that the controller detects the maximum distance of the obstacle to be 2m, that is, when the distance between the key body position and the obstacle is less than 2m, the key body position is determined as the key target body position, when the distance between the key target body position and the obstacle is d <1m, the prompter generates A1dB (decibel) sound signal and/or B1hz vibration signal under the control of the controller; when the distance between the target body key position of the obstacle and the obstacle is 1m & lt d & gt 2m, the prompter sends out an A2dB sound signal and/or a B2hz vibration signal under the control of the controller.

The distance between the blind user and the obstacle is accurately reminded, the distance between the blind user and the obstacle can be accurately reminded, and the blind user can accurately grasp the distance between the blind user and the obstacle, so that the travel of the blind user is facilitated.

In some embodiments, the controller is connected to each sensor and each prompter through wires to realize wired communication. For example, the sensor, the reminder, and the controller may be in communication via conductive sewing thread.

Optionally, the controller may also communicate with each of the sensors and each of the prompters in a wireless communication manner to perform information interaction.
