Description

Smart home perception and control system

technical field

The invention relates to an intelligent home application system, in particular to the fields of family information collection, home appliance intelligent control and home intelligent monitoring.

Background technique

With the development of economy and technology, automation and intelligence have been widely used in the industrial field. People hope to have a system in the home to replace people to a certain extent, and manage the whole family intelligently without human operation. , When an abnormal situation occurs, it can also respond quickly instead of a human. On the other hand, family safety and personal health issues are attracting more and more people's attention. People hope that no matter where they are, they can keep abreast of home information, deal with emergencies, and realize remote monitoring; Professional doctors conduct various inspections on their own health conditions to detect diseases in time. Chinese patent application publication number CN 1018072A, application publication date 2010.08.18, the name of the invention is smart home monitoring system, the application discloses a smart home monitoring system, the monitoring ability of the home monitoring system is very strong, its shortcomings The reason is that after the detection problem occurs, the system cannot automatically do certain work, and the safety factor is poor. Chinese Patent Publication No. CN101188042, the date of publication was May 28, 2008. The name of the invention is smart home control and remote alarm device. This application discloses a system for home control and remote monitoring. Less, less intelligent. According to the above requirements, a new smart home perception and control system is needed to realize smart perception, smart control, and remote monitoring.

Contents of the invention

The purpose of the invention is to overcome the deficiencies of the current smart home system, make the system more intelligent, and meet people's requirements for home intelligence, safety and health.

According to technical requirements, the smart home perception and control system includes: a central processing unit platform, a data acquisition system, a home appliance wireless control system, an intelligent monitoring subsystem, an alarm system, a network connection and a touch screen; the data acquisition system includes video images, Collection of various information including temperature and humidity, smoke concentration, noise and human health status. The system processes, analyzes and judges the collected information through the DSP platform; the system intelligently controls the designated home appliances through the radio frequency module; the system uses home broadband or 3G wireless network to connect with the network cloud and fixed mobile phones; Send commands to the system to complete monitoring and control work.

In today's home smart system, the home owner sends commands to the system through certain devices (such as infrared remote controls or mobile phones), and then the system performs corresponding tasks, such as opening curtains and turning on water heaters. Although there is a certain degree of intelligence, it is still inseparable from the participation of people. This system centrally upgrades household electrical appliances and adds wireless radio frequency modules for data transmission. In addition to accepting commands, it can also automatically operate household electrical appliances according to the owner's life rules. The owner of the house opens the curtains after getting up in the morning. After a period of time, the system will automatically open the curtains at this moment every day after a period of time. In the evening, the owner takes a shower after work. After a period of time, the system will automatically turn on the water heater a few minutes before this moment every day. You can take a shower after returning home, and you don’t need to wait any longer. In summer, the owner turns on the air conditioner when he comes home. After a period of time, the system can automatically turn on the air conditioner a few minutes before this time every day, so that the owner can enjoy the coolness after returning home. In addition, when someone at the door wants to enter the door, the camera captures the face, and the system can judge whether it is a specific face. If it is a specific face, the door will be opened, otherwise the door will be kept closed. In this way, the corresponding work can be completed automatically without human operation, which greatly improves the intelligence level of the system.

Today's home intelligent system still only sends an alarm and notifies the owner of the abnormality, and the system cannot automatically handle it in time. After the abnormal situation occurs, the system sends the abnormal image to a specific mobile phone, and extracts information through various sensors and cameras, comprehensively processes it, and judges what kind of abnormality it is. If there is a fire in the room, the system can automatically call the property and fire alarm; if someone burglarizes, the system can automatically call the security and the police, and send the photo of the burglar to the public security department. This greatly improves the safety of the family. Homeowners can also monitor the situation at home in real time through the network. Thousands of miles away, they can still know all kinds of information at home, which enhances the security and stability of the home.

The system includes human health testing sensors, which can measure blood pressure, body temperature, heart rate and other health conditions, and send them to the network data cloud through the network, so that doctors can remotely detect people's physical conditions. In this way, you can get a doctor's diagnosis without leaving home. The network data cloud library can also automatically transmit various home health and beauty knowledge, as well as weather and environment information to the system, so that family members can grasp various information in a timely and efficient manner.

The advantages of the present invention are: high degree of intelligence, without human operation, the system can intelligently complete multiple operations through statistical analysis; high security, can send various abnormal conditions to the home owner in time, and make adjustments according to the abnormal conditions The corresponding processing can be performed, and remote monitoring can be realized; it includes a health collection module, which can enable doctors to make a diagnosis of the body through the network at home; it can obtain various information from the data cloud through the system in time, which is convenient and fast.
