Description
Technical Field
The invention belongs to medical rehabilitation equipment, and relates to an ankle movement detection system.
Background
In the medical field, for patients with abnormal ankle function, the range of motion of the ankle joint of the patient is measured by visual inspection of medical staff or by using a simple angle measuring instrument, and accordingly, a corresponding diagnosis is made. Due to the lag of the measurement means and the measurement technology, a doctor is difficult to accurately master the motion condition of the ankle joint of the patient, and some uncertain factors are brought to the diagnosis of the doctor.
During the rehabilitation process after ankle injury or operation, medical care and rehabilitation personnel have difficulty in making accurate diagnosis of the rehabilitation process of the patient due to no effective data support. This situation greatly affects the patient's rehabilitation process, while also consuming valuable medical resources.
In the aspect of sports training, the lack of accurate cognition on the ankle joint function of the athletes in the training process causes a large injury risk in the training of the athletes. Meanwhile, due to lack of data, scientific motion guidance and correct evaluation cannot be provided for athletes, which greatly influences training efficiency and training results.
Furthermore, ankle sprains are the joints most vulnerable to injury in daily life or sports, and particularly, as the age increases, the sensitivity of sensory nerves and the strength of muscles decrease. Therefore, the ankle sprain of the older people can easily cause fracture. Therefore, the early warning mechanism of the sensing nerves can be effectively activated through the accurate training of the movement of the ankle joint, the muscle strength of the ankle joint is enhanced and protected, and the positive effect of reducing the sprain of the ankle joint is achieved.
In summary, the ankle joint can be measured accurately in real time and data can be provided to medical staff, a rehabilitation teacher and a coach, and the method is an effective method for improving the medical level, improving the training efficiency, shortening the rehabilitation process and self-care to a greater extent.

The gyro detection device is a main detection device and is responsible for detecting the spatial position of the ankle joint, the angle numerical value of each axial direction and the change condition. The detection result is output to the singlechip for processing through an IIC or SPI bus. The gyro detection device uses a device with a measurement rate higher than 200HZ, and meets detection tasks under different working conditions of medical treatment, rehabilitation and exercise.
The singlechip core circuit automatically performs the Bluetooth pairing task, ensures that the communication connection with an upper system is quickly established after the singlechip core circuit is started, and forms the detection data into a standard data format to be sent out through the Bluetooth data transmission circuit; reading detection data of a gyro detection device through an IIC or SPI bus, and adopting different data processing algorithms according to different task requirements; monitoring the system running condition through the charging and discharging circuit, calculating the remaining time of the work, and sending notification information when the remaining electric quantity of the power supply does not exceed the remaining time of the work; the LED indicating lamp is driven, and the working state is conveniently displayed to a user.

The attached drawing is a structural schematic diagram of the invention.
In the figure: 1 a micro battery; 2, a gyro detection device; 3, a core circuit of the singlechip;

Detailed Description
Before use, a standard 5V dc power supply is connected to the charging interface 7. At this time, the charging circuit 5 charges the micro battery 1 of the present invention until the micro battery 1 is fully charged regardless of whether the power switch 6 is on or off.
When in use, the invention is arranged at the sole or heel, and the power switch 6 is switched on. At this time, the power supply of the present invention is turned on to start the operation. In operation, the gyro detection device 2 detects the spatial attitude of the present invention at a rate of 200 times per second. Since the present invention is tightly fixed with the sole or heel of foot, the data detected by the gyro detection device 2 represents the relative spatial position of the foot and ankle joint. The single chip microcomputer core circuit 3 reads the detection result of the gyro detection device 2 at a rate of 200 times per second through the IIC or SPI bus. The singlechip core circuit 3 carries out corresponding data processing on the read data and the data of a previous period of time according to different states of medical treatment, training and rehabilitation. The single chip core circuit 3 forms the processed data into a standard data format and sends the standard data format out in a wireless mode through the Bluetooth data transmission circuit 4.
When the singlechip core circuit 3 detects that the voltage of the micro battery 1 is too low, the Bluetooth data transmission circuit 4 sends data of low voltage, and the LED indicator light 8 is driven to flicker to indicate that the working voltage is too low.
The design of the invention can meet the requirement that the invention can work normally when the charging circuits 5 all charge the micro battery 1 in the invention. Only at this time, the application range is limited to a certain extent due to the limitation of the length of the power line.
