Simply installing the smart home system can realize simple installation without destroying the partition wall and buying new electrical equipment. The system can be completely connected to the existing electrical equipment in your home, such as lamps, telephones and household appliances. Intelligent subsystems such as various electrical appliances can be controlled at home, and can also fully satisfy remote control. The extensible smart home system is an extensible system. Your smart home system can only be connected with lighting equipment or common electrical equipment at first, and other equipment can be connected in the future to meet the new smart life needs. Even if your home has been decorated, you can easily upgrade to a smart home. The wireless control smart home system can realize intelligent control without destroying the original decoration, as long as the corresponding modules are installed in some sockets and other places, and the original house walls will not be destroyed. Design principles Smart home is also called smart residence. Generally speaking, it is a networked smart home control system integrating automation control system, computer network system and network communication technology. To measure the success of an intelligent system in a residential area, we should not only look at the number of intelligent systems, the advanced nature or integration of the system, but also look at whether the design and configuration of the system are economical and reasonable, whether the system can run successfully, whether the system is convenient to use, manage and maintain, and whether the technology of the system or product is mature and applicable. In other words, how to use the least investment, the simplest way, in exchange for the greatest efficacy, to achieve a convenient and high-quality life. In order to achieve the above goals, the design of smart home system should follow the following principles: practicality and convenience. The basic goal of smart home is to provide people with a comfortable, safe, convenient and efficient living environment. For smart home products, the most important thing is to take practicality as the core and abandon those flashy functions that can only be used as decoration. The products are mainly practical, easy to use and humanized. We believe that when designing a smart home system, we should integrate the following most practical and basic home control functions according to the user's demand for smart home functions: including smart home appliance control, intelligent lighting control, electric curtain control, burglar alarm, access control intercom, gas leakage and so on. At the same time, it can also expand the value-added functions of services such as three-meter cc and video on demand. Many personalized smart homes have many control methods, such as local control, remote control, centralized control, mobile phone remote control, induction control, network control, timing control and so on. It is intended to get rid of cumbersome things and improve efficiency. If the operation flow and program settings are too complicated, users will easily feel excluded. Therefore, in the design of smart home, we must fully consider the user experience, pay attention to the convenience and intuition of operation, and it is best to use a graphical control interface to make the operation WYSIWYG. Reliability If the intelligent subsystem of the whole building can run 24 hours, the security, reliability and fault tolerance of the system must be highly valued. For each subsystem, take corresponding fault-tolerant measures in power supply and system backup to ensure the normal and safe use of the system, good quality and performance, and have the ability to cope with various complex environmental changes. The design of standard smart home system scheme should be carried out in accordance with relevant national and regional standards to ensure the expansibility and expansibility of the system, and the system transmission should adopt standard TCP/IP protocol network technology to ensure the compatibility and interconnection of systems among different manufacturers. The front-end equipment of the system is multifunctional, open and extensible. For example, the host, terminal and module of the system adopt standardized interface design, which provides an integrated platform for external manufacturers of home intelligence systems and has expandable functions. When functions need to be added, there is no need to excavate the pipe network, which is simple, reliable, convenient and economical. The system and products selected in the design can make the system interconnected with the third-party controlled equipment developed in the future. Whether the installation of convenient wiring is simple or not is directly related to the cost, expansibility, maintainability and other issues. Be sure to choose a system with simple wiring, which can be wired with residential broadband in the construction, which is simple and easy; The equipment is easy to learn, master, operate and maintain. The convenient design of the system in engineering installation and debugging is also very important. A remarkable feature of home intelligence is that the workload of installation, debugging and maintenance is very large, which requires a lot of manpower and material resources and has become a bottleneck restricting the development of the industry. In order to solve this problem, the convenience of installation and maintenance should be considered when designing the system, such as remote debugging and maintenance of the system through the Internet. Through the network, not only residents can realize the control function of the home intelligent system, but also engineers can remotely check the working condition of the system and diagnose the faults of the system. In this way, system settings and version updates can be carried out in different places, which greatly facilitates the application and maintenance of the system, improves the response speed and reduces the maintenance cost. Data security In the gradual expansion of smart home, more and more devices will be connected to the system, which will inevitably produce more operation data, such as temperature and clock data of air conditioner, switch status data of indoor windows, gas meter data and so on. These data have an unprecedented correlation with the privacy of a single family. Careless data protection will not only lead to the disclosure of extremely private data such as personal habits, but also directly endanger the family safety in family safety-related data, such as window status. At the same time, the smart home system is not isolated from the world, and the data entering the system needs to be audited to prevent malicious damage to the home system and even the networked household appliances. Especially in today's era of big data, we must guard against the security of family big data.
