Example one
Fig. 1 is a schematic flow chart of an information reminding method based on a blind guiding walking stick in the embodiment of the invention. As shown in fig. 1, an embodiment of the present invention provides an information reminding method based on a blind guiding stick, which is used for a blind guiding stick, wherein a dangerous vibrator, a road induction detector, a road language indicator and a traffic light warning device are arranged in the blind guiding stick, and the method includes:
step 110: and acquiring road information in front of the blind guiding walking stick according to the road induction detector.
Specifically, the shape of the blind guiding walking stick can be designed according to actual needs, in this embodiment, the shape of the blind guiding walking stick is an "L" shaped structure, wherein the short side part of the L shape is a handle and is a holding part for a user, that is, the user can hold the holding part with a hand when going out, and the blind guiding walking stick can also be designed into a straight-line structure. And a road sensing detector, a danger vibrator, a road language indicator and a traffic light warning indicator are sequentially arranged in the blind guiding walking stick from bottom to top, and meanwhile, a battery pack is arranged at the holding part of a user and provides power and a power supply for the blind guiding walking stick. When a user is in an outgoing environment, the road sensing detector is installed at the position, close to the bottom, of the blind guiding walking stick, and the road information in front of the blind guiding walking stick is collected, namely the environment information of the position, in front of the walking of the user, is obtained.
Step 120: and obtaining the information of the obstacles in front of the user according to the road information.
Specifically, the obstacle is an object appearing in front of the user walking, and after the environment information of the position in front of the user walking is acquired, the obstacle in the environment in front of the user walking can be determined and obtained from the environment information, for example, a tree and a sign are arranged in front of the user walking, or a dynamic object such as a cat, a dog, an automobile and the like may threaten the safety of the user.
Step 130: and obtaining the current position information of the user according to the GPS.
Step 140: and obtaining a first distance according to the obstacle information and the current position information.
Specifically, the current position information is the current position of the user, and the distance between the obstacle information and the current position can be obtained by combining the obstacle information and the current position after the position information of the user is obtained. The current position information of the user can be acquired by using a GPS (global positioning System), the GPS is a short name of an English G l oba l Pos itioni System, and a System for real-time positioning and navigation in a global scope by using a GPS positioning satellite can provide navigation information such as a low-cost and high-precision three-dimensional position, speed, accurate timing and the like for the global user, is an application model of a satellite communication technology in the navigation field, greatly improves the informatization level of the global society, and powerfully promotes the development of digital economy. For example, when a user goes out from home to school, the environmental information of the position in front of the user can be acquired through the road sensing detector in the blind guiding walking stick during walking, if a tree appears in front of the user, the current position information of the user is acquired by using the GPS, the distance between the current position of the user and the tree can be calculated through the current position of the user and the position of the tree, and then the distance is judged to remind the user to take an avoidance measure in time.
Step 150: and obtaining a first security level according to the first distance.
Step 160: and judging whether the first security level is smaller than a preset threshold value.
Specifically, the first security level is a security level corresponding to the first distance, and after the distance between the current position of the user and the obstacle is obtained, the corresponding security level may be obtained according to the distance, and then it is determined whether the first security level corresponding to the first distance meets a predetermined condition, that is, it is determined whether the first security level is smaller than a preset threshold. For example, when a user goes out from home to school, on the way of walking, the road sensing detector in the blind guiding cane can acquire that a tree appears in front of the user, the distance between the user's current position and the tree is calculated to be 30m, and the safety level corresponding to the distance of 0-50m is the first safety level, and the safety level corresponding to the distance between the user and the tree is the first level at this time, and the security level corresponding to 50m-100m is a second security level (excluding 50m), the security level corresponding to 100m-150m is a third security level (excluding 100m), when the preset threshold is the third security level, then, it is indicated that the first security level at this time is smaller than the preset threshold, and a reminding message needs to be further sent to the user to prevent the user from having a security accident.
Step 170: and when the current safety level is smaller than the preset threshold value, the dangerous vibrator sends a first reminding signal to the user according to a first vibration mode corresponding to the first safety level.
Specifically, when the first safety level is smaller than the preset threshold, the dangerous vibrator installed above the road sensing detector adopts a corresponding vibration mode and serves as a reminding signal to be sent to the user. Specifically, the method comprises the following steps: the vibration modes of the dangerous vibrators are different aiming at different safety levels, when the safety level is the first safety level, the corresponding vibration mode is the first vibration mode, when the safety level is the second safety level, the corresponding vibration mode is the second vibration mode, therefore, a user can obtain different reminding signals according to different vibration modes, certain judgment is carried out on the danger level of the obstacle in front, and the user can take danger avoiding measures in time aiming at different reminding signals. Furthermore, when a user moves in a shopping mall, due to the fact that the space inside the shopping mall is large and public facilities are dense, under the combined action of the road sensing detector and the dangerous vibrator, when obstacles such as guardrails, models and counter arranged in front of the walking of the user appear, warning signals can be timely transmitted to the user through the dangerous vibrator; furthermore, when the user wants to go to a certain storefront for shopping in the shopping mall, the user can be guided to go to the desired place by the real-time navigation for the user under the guidance of the road language indicator.
Further, the method further comprises: obtaining traffic light information in front of the moving direction of the user according to the traffic light warning indicator, wherein the traffic light information comprises the color and the display time of the current indicator light; obtaining the current moving speed of the user; obtaining the first time of reaching the intersection according to the current moving speed; judging whether the display time is less than the first time or not; when the time is less than the first time, obtaining a second security level according to the first time and the display time; and the dangerous vibrator sends a second reminding signal to the user according to a second vibration mode corresponding to the second safety level.
Specifically, a traffic light warning device installed on the blind guiding cane can acquire traffic light information of an intersection where a user is located, wherein the traffic light information includes color and display duration of a traffic indicator light, when the color of the indicator light is a green light, further, according to the distance of the intersection and the average moving speed of the user, the time used by the user to pass through the intersection can be calculated, then, the passing time required by the user and the display duration of the green light are compared, whether the passing time required by the user is longer than the display duration of the green light at the intersection is judged, when the passing time required by the user is longer than the display duration of the green light at the intersection, the user cannot smoothly pass through the intersection within the display duration of the green light according to the average moving speed of the user, further, according to the passing time required by the user and the display duration of the green light at the intersection, and obtaining a second safety level, wherein the vibration mode corresponding to the second safety level is a second vibration mode, and then the dangerous vibrator sends a second reminding signal to the user according to the second vibration mode corresponding to the second safety level to inform the user that the user needs to pause to advance and wait for the next green light to pass through the intersection. Therefore, the safety of the user when the user passes through the road is ensured, and the safety accident caused by the fact that the user cannot pass through the road smoothly within the specified time is prevented. For example, when a user passes through an intersection, the display time length of the green light at the moment is 7s, the distance from the intersection is 15m, and when the average moving speed of the user is 1m/s, it indicates that the user smoothly passes through the intersection, the required time is 15s, and the display time length of the green light at the moment obviously cannot meet the passing requirement of the user, so that the user cannot safely pass through the intersection within the remaining time, at the moment, the dangerous vibrator sends a second reminding signal to the user according to a second vibration mode corresponding to a second safety level to inform the user that the user needs to pause to advance, and the user can pass through the intersection before the next green light appears.
Further, the method further comprises: obtaining target path information of the user, wherein the target path information is provided with a preset electronic fence; judging whether the current position information of the user is within the range of the electronic fence or not; and when the road language indicator is not in the state, the road language indicator outputs voice information and sends a third reminding signal to the user.
Further, the outputting of the voice message by the road language indicator, after sending a third warning signal to the user, further includes: acquiring second path information according to the target path information and the current position information of the user; and the road language indicator carries out real-time navigation for the user according to the second path information.
Specifically, the target path information is a route planned by the user, the user can go to a destination to be reached according to the target path, and meanwhile, the target path information also has a certain preset electronic fence, that is, in the range of the electronic fence, the user can be ensured to smoothly and accurately reach the destination according to the movement of the target path. Further, when the current position of the user is determined, that is, whether the current position of the user is located in the preset electronic fence is determined, and when the current position of the user is not located in the range of the electronic fence, the user is indicated to deviate from the track of the target path, at this time, the road language indicator outputs voice information, a third prompting signal is sent to the user to inform the user that the user deviates from the target track and needs to return to the preset electronic fence range, further, the blind guiding walking stick is re-planned for the user according to the target path information and the position of the user at this time, namely, the second path information is obtained, and then the user is navigated in real time under the guidance of the second path information through the road language indicator, the user can timely acquire the correct route after deviating from the target route, and time waste caused by walking by mistake is avoided.
Further, the method further comprises: obtaining posture information of the user; judging whether the posture information of the user meets a preset condition or not; and when the preset condition is not met, sending the current position information and the rescue information of the user to a contact of the user.
Specifically, the posture information is motion information that the body of the user presents, and generally, when the user is in a normal state, the user presents a stooped posture when stooping, a walking posture when walking, and a sitting posture when sitting and resting. Therefore, after the posture information of the user is obtained, whether the posture of the user meets a preset condition can be judged, namely whether the posture information of the user presents a state under a normal condition is judged, when the preset condition is not met, the situation that the user possibly presents a dangerous condition is shown, at the moment, a guardian of the user needs to be informed timely, the position information of the user is sent to the guardian of the user, the guardian of the user is reminded of reminding the guardian of the user that the user possibly presents a dangerous condition and needs to be rescued, meanwhile, the user can automatically make a call to an emergency center, the position information of the user is told to a rescuer, the user is helped to break away from the dangerous situation timely, and tragedy caused by untimely rescue is avoided. For example, when a user goes out alone, the blind guiding stick monitors that the posture of the user is a state of falling on the ground, and the state of the user indicates that the user may have poor physical condition or an accident occurs and needs to send a rescue signal to the outside in time, so that the current position information and the rescue information of the user can be sent to a contact of the user, and meanwhile the rescue information can also be sent to a rescue center.
