Description

Intelligent walking stick capable of intelligently judging whether user falls down

Technical Field

The invention relates to the technical field of intelligent auxiliary instruments, in particular to an intelligent walking stick device capable of intelligently judging whether a user falls down.

Background

With the age, the physical function is gradually degraded, the strength, the flexibility and the coordination ability are gradually reduced, and the walking stick becomes a great tool for assisting the life of the old. In addition, there are some people with mobility disabilities who need to walk with the aid of a walking stick to facilitate their activities within a certain range or to accelerate the recovery of injured people. Therefore, how to use the walking stick to provide better life assistance for the old and the handicapped becomes a research hotspot in recent years.

With the development of science and technology, multifunctional integration and intellectualization of the walking stick become possible. In addition to improvements in shape and materials, more and more canes are beginning to integrate functions such as GPS positioning, lighting, MP3 playing, emergency warning, etc. However, the intelligent technology of the existing walking stick obstacle detection system is less in application, the screen display key operation is complex, and the problem that a user falls down cannot be effectively solved.

Physical injury and physiological change caused by falling down can cause the attack of diseases such as cardiovascular and cerebrovascular diseases and even cause syncope, thereby losing the chance of calling for help by oneself. In addition, the serious consequence of falling down can also cause harm to mental health, the fear after falling down can increase the risk of falling down and relapse, and statistics shows that two thirds of old people fall down again in the second year of falling down. Therefore, the timely discovery and rescue of falling have important significance for the physical and psychological health of the old.

Although walking aids may be provided by walking sticks, the user may still fall due to an unstable center of gravity or sudden syncope from chronic diseases (e.g., cardiovascular diseases, diabetes, etc.). If the user goes down to a coma or is unable to ask for help, the danger alarm of the prior walking stick loses the function. Therefore, it is very necessary to integrate physiological abnormality monitoring and fall detection on the walking stick and perform automatic alarm in case of abnormality. Although some intelligent walking sticks have the function of fall detection, the walking sticks are usually monitored only by using a gyroscope, and if a user places the walking stick horizontally, the situation of false alarm of the falling of the walking stick can be caused; the intelligent walking stick that has alarming function at present is more single in form, lacks external contact function, and user's guardian can't receive alarm information in real time, if the user is in the occasion that personnel are rare, appears nobody help easily, can't in time send the condition of seeking help information in order to seek help.

The heart rate monitor, the Bluetooth module, the memory module, the mobile communication module and the GPS positioning communication module can realize real-time heart rate monitoring and alarming functions. Collecting user heart rate information using the heart rate monitor. The heart rate monitor directly adopts the existing mature products on the market, adopts a photoplethysmography (PPG) method, acquires the pulsatility change of the blood volume of peripheral micro-vessels along with the heart pulsation by real-time tracing the light absorption of the detected part, and calculates to obtain the heart rate. The heart rate monitor emits light to the skin, and converts received optical signals into electric signals through a photoelectric receiving tube at a receiving end. Because the absorption of skin, muscle, skeletal tissue and the like to light basically keeps unchanged, the volume of blood in the skin changes in a pulsating manner under the action of the heart, when the heart contracts, the peripheral blood volume is the largest, the light absorption amount is the largest, and the detected light intensity is the smallest; the detected light intensity is maximum when the heart is in diastole, so that the electric signal converted by the light intensity received by the photoelectric receiver is in pulsatile change along with the contraction and the diastole of the heart, and the change of the volume pulse blood flow is reflected. And obtaining the corresponding heart rate according to the number of wave crests of the PPG signal in a certain time. Assuming that the time of continuous sampling t seconds, the number of peaks in t seconds is N, and then the heart rate value is calculated to be N x 60/t. And storing the heart rate value obtained by calculation into a memory module, and transmitting the heart rate value to a matched APP of the mobile terminal of the user through a Bluetooth module. If the monitored heart rate information is larger than a certain range compared with the pre-stored initial heart rate, for example, alarm information is sent when 20%, and the specific value can be set or modified according to the medical recommendation value. Meanwhile, the heart rate information of the user is sent to the APP matched with the intelligent walking stick of the guardian through the mobile communication module, and the guardian can know the real-time geographic position information and the heart rate health information of the bound walking stick user through the APP matched with the guardian.

The binding of the intelligent walking stick and the APP matched with the mobile terminal is realized through the Bluetooth module. When a user registers an APP, the identity of the user is selected according to the prompt, and the APP binding module and the intelligent walking stick which are matched with the mobile terminal establish communication connection through the Bluetooth module, so that the intelligent walking stick and the APP are bound; when registering the APP, the guardian selects the identity of the guardian according to the prompt, and inputs the ID information of the intelligent walking stick according to the APP guide information to be bound with the user.

Since the propagation velocity of the ultrasonic wave in the air is a known fixed value, the actual distance from the transmitting point to the obstacle can be calculated based on the time difference between the transmission of the ultrasonic wave and the reception of the reflected wave and the propagation velocity of the ultrasonic wave in the air. An alarm threshold value (such as 0.8 meter) is set and prestored in the memory according to experience, when the distance between the detected front obstacle and a user is smaller than the threshold value prestored in the memory, the signal controller sends a signal to start the vibrator to prompt that the front obstacle exists, and the vibration is strengthened along with the shortening of the distance so as to remind the user to avoid the front obstacle. The front barrier reminding is carried out through the vibration of the vibrator, the barrier avoiding reminding function for common people and people with visual/hearing disabilities can be met, and meanwhile, the noise pollution to the surrounding environment when the loudspeaker is used is avoided.

The intelligent walking stick has various alarm forms, and an acceleration sensor and a pressure sensor are combined to be used besides a common gyroscope. The monitoring data of the three sensors are integrated to carry out falling detection, so that falling behaviors can be judged more accurately to reduce misjudgment, and falling misjudgment caused by the sliding of the walking stick can be further reduced by combining with a hanging rope hung on the wrist. The intelligent walking stick comprises a storage module, an acceleration sensor, a gyroscope, a pressure sensor and a processor module, wherein the acceleration sensor, the gyroscope and the pressure sensor are used for collecting data, the processor module is used for analyzing the data and storing the data into the storage module, and when the acceleration monitoring data of the intelligent walking stick, the angle data of the gyroscope and the pressure data are detected to be changed, the acceleration monitoring data and the angle data of the gyroscope are compared with a data range prestored in the storage module to judge whether the intelligent walking stick falls down. If the walking stick falls down due to the action of external force when the walking stick is placed statically, the walking stick can be judged not to be used because no pressure is detected before the walking stick falls down, and therefore the user cannot be judged to fall down; when a user horizontally places the intelligent walking stick, the monitoring data of the acceleration sensor is in the data range initially set by the memory module, so that the situation that the intelligent walking stick does not fall can be judged; when a user vertically waves the intelligent walking stick or taps the ground at a higher speed, the angle data of the gyroscope is in the data range initially set by the memory module, so that the situation that the user does not fall can be judged; when the user holds the intelligent walking stick to fall, the monitoring data of the acceleration sensor, the gyroscope and the pressure sensor exceed the data range initially set by the memory module, so that the falling behavior of the user can be judged. When the intelligent walking stick is applied specifically, the intelligent walking stick can be processed by combining with actual conditions, if the monitoring data of the acceleration sensor, the gyroscope and the pressure sensor are all located at the edge of the data range initially set by the memory module, and whether the intelligent walking stick falls down or not can not be accurately judged, the signal controller of the intelligent walking stick sends out a control signal, and the audible and visual alarm is automatically started after a certain time.

Referring to fig. 2 and 3, in the invention, an illuminating lamp switch button 16 and a heart rate monitor 17 are arranged above the handle 2 of the walking stick, so that a user can conveniently monitor the heart rate in real time and display the heart rate in a matched APP, and if the heart rate is abnormal, an alarm can be given at the first time and information can be transmitted to a guardian. A height adjusting hole 13 is arranged below the walking stick rod 1, and the length of the walking stick can be adjusted according to different users and different using modes by combining a telescopic fixing buckle 19 so as to better meet different requirements of the users;

when the electric quantity of the intelligent walking stick is sufficient, the breathing lamp 7 is displayed as green; when the electric quantity of the intelligent walking stick is insufficient, the breathing lamp 7 turns red to prompt that the intelligent walking stick needs to be charged in time; the breathing light 7 red light is flashing when charging. If the user continuously presses the emergency help-seeking button 8, the audible and visual alarm 9 is automatically turned on, the loudspeaker 011 sends out 'please help me' to remind surrounding people to help, and simultaneously, the emergency help-seeking information and the real-time position information are displayed in a matched APP and sent to a guardian; if the user is judged to have a falling behavior according to the data monitored by the gyroscope 004, the pressure sensor 002 and the acceleration sensor 003, the audible and visual alarm 9 is automatically turned on, and simultaneously, falling information and the information of the geographical position of the user are automatically displayed in a matched APP in real time and sent to a monitor; if the user does not fall down or does not need help from others, the audible and visual alarm 9 and the loudspeaker 011 can be manually turned off by pressing the emergency help button 8 once. If an obstacle is detected in front by the ultrasonic sensing module 006 and the distance is less than a preset threshold value of 0.8 m, the vibrator 013 gives a vibration prompt, and the closer to the obstacle, the stronger the vibration is.

The working principle is as follows:

GPS orientation module 010 mainly used acquires the real-time positional information at intelligent stick place, and through current mobile communication network, positioning accuracy is higher, and speed is very fast, and user's guardian can learn user place geographical positional information in real time through the supporting APP of intelligent stick.

The ultrasonic sensing module 006 is used to implement an obstacle detection function. The ultrasonic waves can generate obvious reflection when contacting impurities or interfaces to form reflection echoes, and the distance of the obstacle can be calculated according to the transmitting/receiving time of the ultrasonic waves. When the distance between the detected front obstacle and the user is smaller than the threshold value prestored in the memory, the vibrator is started to vibrate for reminding, and vibration is increased along with the shortening of the distance.

The acceleration sensor 003, the gyroscope 004 and the pressure sensor 002 collect data, the data are analyzed through the processor module 001 and stored in the memory module 008, and after the acceleration monitoring data of the intelligent walking stick of a user and the angle data and pressure data of the gyroscope are detected to be changed, the acceleration monitoring data and the angle data and the pressure data of the gyroscope are compared with a data range prestored in the memory module 008 to judge whether the intelligent walking stick falls down. If the walking stick falls down due to the action of external force when the walking stick is placed statically, the walking stick can be judged not to be used because no pressure is detected before the walking stick falls down, and therefore the user cannot be judged to fall down; when the user horizontally places the intelligent walking stick, the monitoring data of the acceleration sensor 003 is in the data range initially set by the memory module 008, so that it can be judged that no falling behavior occurs; when a user vertically waves the intelligent walking stick or taps the ground at a higher speed, the angle data of the gyroscope 004 is in the data range initially set by the memory module 008, so that the user can judge that the falling behavior does not occur; when the user falls with the intelligent walking stick, the monitoring data of the acceleration sensor 003, the gyroscope 004 and the pressure sensor 002 all exceed the data range initially set by the memory module 008, so that the falling behavior of the user can be judged. In the concrete application, can combine actual conditions to handle, if acceleration sensor 003, gyroscope 004 and pressure sensor 002's monitoring data all are in memory module 008 initial settings's data range edge, because of can't accurate judgement whether take place the action of tumbleing, at this moment intelligent stick's signal controller 007 sends control signal, opens audible-visual annunciator 9 automatically after the certain time. If the user does not fall or does not need help, the intelligent walking stick can be picked up in a set time or the audible and visual alarm 9 can be turned off manually, otherwise, the user is judged to fall and needs help, audible and visual alarm is continuously carried out, and information is sent to a guardian. If the intelligent walking stick is picked up within a set time, monitoring data of the gyroscope 004 and the pressure sensor 002 are in a data range initially set by the memory module 008 within the set time, and the signal controller 007 sends a signal to automatically turn off the audible and visual alarm 9; otherwise, the audible and visual alarm 9 is continuously turned on until the audible and visual alarm 9 is manually turned off.

When the falling behavior is judged, the invention adopts an online and offline double-help calling mode to start double guarantees. Signal controller 007 of intelligence stick will send signal, opens audible-visual annunciator 9 and speaker 011, attracts people around to notice to and obtain the help in time, meanwhile through bluetooth module 005 with alarm information transmission to the supporting APP of user on, GPS location communication module 010 sends user place geographical position information to supporting APP, and send alarm information to the supporting APP of user's guardian through mobile communication module 009 on.

The emergency help button 8 can realize the emergency help function, and the signal controller 007 sends a control signal by continuously pressing the emergency help button 8 twice, so that the audible and visual alarm 9 and the loudspeaker 011 are turned on, and meanwhile, emergency help information is sent to the guardian. If the emergency help-seeking button 8 is touched by mistake, the audible and visual alarm 9 can be closed by pressing the emergency help-seeking button 8 again under the opening state of the audible and visual alarm 9, and the emergency help-seeking is cancelled.

The heart rate monitoring module converts the light intensity which changes with the pulsatility of the heart beat into an electric signal, and then calculates to obtain the heart rate. The heart rate monitor emits light to the skin, and converts received optical signals into electric signals through a photoelectric receiving tube at a receiving end. Because the absorption of skin, muscle, skeletal tissue and the like to light is basically kept unchanged, the blood volume in the skin is pulsated and changed under the action of the heart, when the heart contracts, the peripheral blood volume is the largest, the light absorption amount is the largest, and the detected light intensity is the smallest; the opposite is true when the heart is in diastole, the detected light intensity is maximum, so that the electric signal converted by the light intensity received by the photoelectric receiver is in pulsatile change along with the contraction and the diastole of the heart, and the change of the volume pulse blood flow is reflected. And obtaining the corresponding heart rate according to the number of wave crests of the PPG signal within a certain time. Assuming that the time of continuous sampling t seconds, the number of peaks in t seconds is N, and then the heart rate value is calculated to be N x 60/t. The calculated heart rate value is stored in the memory module 008 and transmitted to the APP of the user mobile terminal through the bluetooth module 005.

When the monitoring data of heart rate monitoring module is not in the data range that memory module 008 prestores, can arouse signal controller 007 to send alarm signal to send the abnormal information of rhythm of the heart to the supporting APP of user through bluetooth module 005, remind the user in time to pay close attention to the information of rhythm of the heart unusual, meanwhile GPS location communication module 010 and mobile communication module 009 send the real-time position information of user and the abnormal information of rhythm of the heart to the supporting APP of user's guardian.

In conclusion, the intelligent walking stick device provided by the invention can provide functions of walking assistance, falling detection, obstacle detection, heart rate monitoring, emergency medicine storage, real-time positioning, illumination, player and the like, can be used for emergently seeking help and giving an alarm when an abnormality occurs, has functions of manual alarm, automatic alarm, remote alarm and false alarm removal, enriches the alarm diversity, and effectively improves the intelligent degree and the false alarm prevention performance of the alarm. Through the binding of matched APP and information, the guardian can acquire the distress alarm information and the real-time position information of the user at the first time so as to take corresponding measures in time, thereby better providing the guardianship auxiliary service for the user.
