Based on the current sharing technology at home and abroad, this project has developed a care system for the elderly with the functions of information collection and sharing, intelligent control, intelligent anti-fall warning and remote monitoring, so as to improve the quality of care, solve the problem of "empty nest hidden danger" and realize all-round protection for the elderly. The project integrates key technologies such as sensors, intelligent control, wireless communication, network connection and data processing, data transmission, voice recognition, etc., and uses sensor detection and data processing technology to obtain reliable, accurate and useful detection information in real time. Through the intelligent control of the voice recognition system, the home is automatically controlled to realize the intelligent control function of the system. GPS positioning technology is used to locate the position of the elderly to prevent the elderly from losing. The network communication technology combining local area network and Internet is adopted to realize data transmission, video monitoring and real-time control. Through heart rate sensor, acceleration sensor and other modules, the physical state of the elderly is detected in real time, and the health information of the elderly is transmitted to APP through the Internet. Targeted around the "care for the elderly" to carry out smart home design, the function is more comprehensive, the operation is more simple. The details are as follows: 1. Intelligent security system: The complete intelligent security system includes gateway, camera, alarm, door magnet, intrusion detector and access control. Due to different customer needs, we generally increase or decrease according to demand. This system can realize automatic arming and disarming according to the needs of users, and can realize remote control and remote viewing intercom. 2. Intelligent lighting system: mainly includes intelligent switches, intelligent sockets, scene switches and intelligent lights. One-key scene control can be realized, which can not only meet the demand to the greatest extent, but also save electricity as much as possible. It allows users to turn off the lights at night or when they leave home, or turn on the lights at home. 3. Electric windows and electric curtains: use motors to push windows and open curtains, and use intelligent controllers to control motor switches to realize intelligent windows and curtains. Not only can be linked with carbon dioxide detector, temperature and humidity detector, light detector, once the temperature, carbon dioxide concentration or light intensity reaches the set value, it is automatically turned on or off. You can also use the mobile control terminal to remotely control the curtain window switch to prevent rainwater immersion. 4. Anti-loss system: the use of GPS positioning function to prevent the loss of the elderly, but also through the photo to confirm the identity of the remote door function, greatly improving the safety of the elderly. 5. Intelligent kitchen: the main products are combustible gas detector. If the detector detects the leakage of combustible gas, it will automatically alarm; automatically open the power window, air circulation, to avoid indoor toxic gas concentration is too high. The function can be realized automatically, and the mobile phone will also receive an alarm. 6. Fingerprint identification system; use the sensor to collect the user's fingerprint and record it in the database. When the user scans, it also detects whether it is human body pressing, which can prevent criminals from using the fingerprint model to crack. 7. Face recognition system: use the camera to record the user's facial feature information, when the user enters the door, compare the face, and at the same time detect whether it is a living face, rather than a photo or face mold. 8. Health detection system: Based on the blood oxygen heart rate sensor and the hexapod acceleration sensor, the acceleration and angle of human body dumping are calculated in combination with the autonomous algorithm to make a judgment on whether or not to fall, and the judgment result is transmitted to the APP on the family's mobile phone in time to facilitate the family to arrive for help or treatment in time.
