Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: a shoe body 1, a rotating disc 2 and an indicator light 3.
The embodiment is basically as shown in the attached figure 1: patient's walking exercise intelligence shoes includes: the shoe comprises a shoe body 1, a posture sensing module, an angle adjusting module, a control module and an input module.
The posture sensing module is fixed on the shoe body 1 and used for detecting the acceleration and the angle of the shoe body 1. The specific attitude sensing module comprises an acceleration sensor and a gyroscope. The acceleration sensor and the gyroscope can be selected from a plurality of specific models, and the effect to be realized is to detect the acceleration value and the angle of the shoe body 1 in real time. The sensor in the smart phone in the prior art can basically meet the requirements. In this embodiment, WT901 is selected as a sensor module for measuring the motion state of an object with high precision, and integrates a three-axis accelerometer, a three-axis gyroscope, three-axis angle measurement, and geomagnetic measurement. Through high performance MCU and motion sensor BMI160 and magnetic field sensor AK8963, through reading the sensor data, through complicated dynamics resolving and developments Kalman filtering algorithm, obtain comparatively accurate triaxial data, then through TTL level serial ports, come out data transmission. The reason for this is adopted in the embodiment, and the prior art has a mature technology, is directly used and has low cost. And the whole module is integrated into a PCB with the size of a thumb, is thin, does not increase the burden of the shoe body 1, has the thickness of not more than 2mm and the weight of less than 0.6g, supports the communication with a single chip microcomputer, and can reduce the whole power consumption to be very low.
One end of the angle adjusting module is fixed on the shoe body 1, the other end of the angle adjusting module is provided with an indicating lamp 3, and the angle between the angle adjusting module and the shoe body 1 can be adjusted. Specifically, the angle adjustment module comprises a stepping motor and a turntable 2, the turntable 2 is fixed on the side surface of the shoe body 1 (as shown in fig. 2), the stepping motor drives the turntable 2 to rotate, an indicator light 3 is fixed on the turntable 2, and the stepping motor is in signal connection with the control module. In the first solution, the turntable 2 is prepared to be driven to rotate by a speed reduction motor of 8mm, but in the practical application process, the light spots (or marks) are greatly shaken, which is not beneficial to the use of the patient, certainly not unusable, but only has poor effect. Finally, the stepping motor with the model number being DRF-24BYG48-64-1 is selected in the embodiment, and the rated voltage is 5V. Specifically, the LED lamp is selected for use as the indicator lamp in this embodiment.
Control module respectively with gesture response module, 3 signal connection of angle adjustment module and pilot lamp, control module is used for when receiving the ascending acceleration information of the shoes body 1, control pilot lamp 3 lights, according to the contained angle of preset parameter control angle adjustment module and the shoes body 1, regard the facula that pilot lamp 3 left on ground as the mark of patient's training, control module still is used for when receiving the forward acceleration information of the shoes body 1, control angle adjustment module reduces the contained angle with the shoes body 1, so that mark position and ground relatively fixed. Specifically, the single chip microcomputer of the macro-crystal STC8A8K64S4a1 selected by the control module in this embodiment has a relatively high speed.
The input module is in signal connection with the control module and is used for adjusting preset parameters. In this embodiment, the input module selects a key for input, and in other embodiments, the selected WIFI module or bluetooth module performs input.
The preset parameter is stride information. Specifically, the preset parameters can be 10-30cm, and are adjusted according to actual orders and the specific conditions of patients.
The power module chooses for use current millet treasured that charges, and the voltage of output is 5V, can be the power supply of singlechip and other devices basically, and power module fixes at the sole, and power module generates heat in the use and can also provide cold-proof for the user.
The specific implementation process is as follows: firstly, when a user lifts the foot, namely the shoe body 1 moves upwards, the posture sensing module collects acceleration information and feeds the acceleration information back to the control module, and the control module controls the indicator lamp 3 to be lightened after receiving the acceleration information. The control module controls the included angle between the angle adjusting module and the shoe body 1 through simple trigonometric function operation according to preset parameters and the distance between the shoe body 1 and the ground, so that the distance between the light spot of the indicating lamp 3 on the ground and the initial position of the shoe body 1 is the stride suggested by a doctor.
Then, after lifting the foot, the foot of the user can drive the shoe body 1 to move forwards, and the control module controls the included angle between the angle adjusting module and the shoe body 1 according to the forward acceleration information of the shoe body 1, so that the mark position of the light spot on the ground is relatively fixed with the position of the ground, and the function of fixing the mark is achieved.
Specifically, the shape of the light spot of the indicator light 3 on the ground in this embodiment is the shape of a sole. In other embodiments, a scaling module may be disposed on the indicator light 3 to adjust the size of the light spot. The zooming module is in signal connection with the control module, the control module adjusts the size of the light spot according to the distance between the shoe body 1 and the ground, which is detected by the attitude sensing module, so that the light spot is fixed not only on the ground, but also in size, and a better guiding effect is achieved.
In another embodiment, the indicator light is further provided with a filter for changing the color of the light spot. Therefore, different optical filters can be selected according to specific ground colors so as to improve the identification degree under different environments.
Specifically, because in the use, if use gesture response module always to shift and angle and detect always, the error can accumulate always, leads to the effect of last mark to descend, in this embodiment, after shoes body 1 lands, control module can carry out clearance once with gesture response module's data, eliminates the error of accumulation. Namely, each time the user lands on the ground and lifts the foot, new calculation is performed, and error accumulation is avoided. Through practical verification, the error of the embodiment basically moves within 10mm, and the use is not influenced.
Specifically, in the aspect of response time, in the embodiment, the data obtained from the posture sensing module to the angle adjustment of the indicator light 3 are theoretically 0.02 second, but the response time of the body feeling (body feeling) is 0.5 second due to the limited adjustment range. However, since the embodiment mainly aims at the parkinson patient, the corresponding time is widely accepted in practical use, and the next direction for preparing optimization is to optimize the stability.
The foregoing is merely an example of the present invention, and common general knowledge in the field of known specific structures and characteristics is not described herein in any greater extent than that known in the art at the filing date or prior to the priority date of the application, so that those skilled in the art can now appreciate that all of the above-described techniques in this field and have the ability to apply routine experimentation before this date can be combined with one or more of the present teachings to complete and implement the present invention, and that certain typical known structures or known methods do not pose any impediments to the implementation of the present invention by those skilled in the art. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
