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. Specific 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: It mainly includes smart switches, smart sockets, scene switches and smart 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 window and electric curtain: Use the motor to push the window and open the curtain, and use the intelligent controller to control the motor switch to realize the intelligent window and curtain. 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-lost system: The GPS positioning function is used to prevent the elderly from losing, and the remote door opening function is also provided after the identity is confirmed by taking photos, which greatly improves the safety of the elderly. 5. Smart kitchen: The main products are combustible gas detectors. 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; The user's fingerprint is collected by the sensor and recorded in the database. When the user scans, it is detected whether the human body is pressed at the same time, which can prevent criminals from using the fingerprint model to crack. 7. Face recognition system: The camera is used to record the user's face feature information. When the user enters the door, the face is compared, and whether it is a living face, not a photo or a face mold, is detected at the same time. 8. Health detection system: Based on the blood oxygen heart rate sensor and the hexapod acceleration sensor, the acceleration and angle of the human body dumping are calculated in combination with the autonomous algorithm to make a judgment on whether the human body falls down, and the judgment result is transmitted to the family's mobile phone APP in time to facilitate the family to arrive for help or treatment in time.
