step S2, the Bluetooth receiving device receives the pressure signal sent by the Bluetooth transmitting device and transmits the pressure signal to the second single chip processor, and the second single chip processor compares and analyzes the received pressure signal with a preset pressure signal threshold value:
when the pressure values F1 and F3 of the half sole and the arch of the foot become 0 and the duration time exceeds 0.5 second, the second singlechip processor judges that the patient is about to fall backwards, and controls an electronic ignition switch in the safety airbag behind the clothes to start ignition, so that nitrogen is subjected to a reactant chemical reaction to generate nitrogen and fills the airbag;
when the pressure values F2 and F3 of the rear palm and the sole center are changed into 0 and the duration time exceeds 0.5 second, the second singlechip processor judges that the patient is about to fall forward, and controls an electronic ignition switch in the safety airbag in front of the clothes to start ignition, so that the nitrogen is subjected to a reactant chemical reaction to generate nitrogen and fills the airbag.
When the pressure values F1 and F3 of the half sole and the arch of the foot become 0, or the pressure values F1 and F3 of the half sole and the arch of the foot become 0, and the duration time exceeds 0.5 second, the second singlechip processor controls the buzzer to give out alarm sound.
The working principle of the invention is as follows:
the pressure effect can make the cells generate elastic deformation to improve the oxygen uptake of the cells, and cause substances which stimulate the release of the cells around the tissues to inhibit pain to achieve the effect of relieving the pain, and the traditional Chinese medicine has obvious curative effect on the chronic achilles tendinitis. Thus, the present invention controls pronation and supination of the foot through the orthopedic insole, raising the arch of the foot reduces hindfoot eversion, thereby relieving achilles tendon tension, restoring normal foot biomechanical lines and alleviating foot problems due to biomechanical abnormalities. Simultaneously, a pressure sensor and a wireless Bluetooth transmitting device are arranged at the bottom of the insole, and the pressure sensor transmits the collected sole pressure signals to the Bluetooth transmitting device.
The Bluetooth receiving device is arranged on clothes worn by a patient, and the clothes are further provided with an alarm button, a buzzer, a second single chip processor and an air bag. The Bluetooth receiving device receives the collected plantar pressure signals and performs comparative analysis through the data part, so that whether the patient falls is judged. When the collected plantar pressure signals (two feet) are 0 and are still 0 after a period of time delay, the patient can be judged to fall down. And a Bluetooth sensor lamp is added to judge whether the Internet and the insole are in a connection state when the insole is worn.
After the alarm part receives the signal that the patient falls down (after 10 s), the buzzer is automatically triggered to send out a distress signal. The invention adds a manual alarm device at the same time, can automatically operate the button when the user is conscious, and can turn on the buzzer more quickly and give an alarm more timely.
In addition, the invention can not only give an alarm to help when the patient falls down, but also open the protective air bag arranged on the clothes at the moment of falling down, thereby reducing the physical injury of the patient caused by falling down, and the principle of the air bag is the same as that of the automobile safety air bag, and the details are not repeated. The above disclosure of the present invention also provides a specific method for the sensory detection of a patient before a fall.
In summary, the present invention aims to provide a system and a method for early warning and protecting falling based on insole pressure sensing, which can timely find that a patient falls through pressure data acquisition and analysis, reduce the occurrence probability of misjudgment, and improve the accuracy of falling detection. Meanwhile, through the alarm device, the caretaker is reminded to provide rescue for the person who falls in time, and the deepening of the injury degree of the patient caused by falling is reduced. In addition, the invention can alarm and ask for help when the patient falls down, and can open the protective air bag arranged on the clothes at the moment of falling down, thereby reducing the physical injury of the patient caused by falling down.
