Smart Home Control System Functional Design Requirements

When designing a smart home system, the following most practical should be integrated according to the user's needs for smart home functions. Use the most basic functions: including intelligent home appliance control, intelligent lighting control, electric curtain control, anti-theft alarm, access control intercom, gas leakage, etc. At the same time, it can also expand the value-added functions of services such as three-meter copying and video on demand.

The smart home system integrates facilities related to home life through security prevention technology, automatic control technology and audio and video technology - building an efficient management system for residential facilities and family schedule affairs - improving home safety, convenience, comfort and artistry - and realizing environmentally friendly and energy-saving living Environment.

Cabling, and the stability of the whole smart home system. In terms of design, all smart home system products can be designed, but it is recommended to buy a system that can be compatible with multiple devices and multiple brands according to your needs. There are many products. If you need them, you can access them first and continue to expand them later.

The purpose of smart home is to realize the connection between various home devices through wireless connection technology, bringing people a convenience of use. This article will deeply explore the three major considerations of smart home design to help readers better understand the design of smart home.Practicality The first factor that needs to be considered when designing smart home is practicality.

What is system function design

I) System functional structure The basic functions of the information system such as agricultural land division are special land evaluation services, and combined with land management work to realize the informatization and integration of agricultural land division and other work. Transformation.

Operating System (OS) is a program that manages computer hardware and software resources, and is also the core and cornerstone of a computer system.

System design is the second stage of information system development. Its main goal is to design a system solution that meets the needs of users according to the requirements specifications obtained in the system analysis stage.

Detailed design of the main functional modules of the system

1. The main functional modules of the system can be divided into 6 modules, including news section, domestic geological relics, foreign geological relics, geopark research, geopark science popularization, Background maintenance management.

2. In the development and design of the system, four types of functional modules are set according to the purpose to be achieved and the target user object: system management and maintenance function, daily business management function, agricultural land division and other special functions and expert support function modules. The functional structure of the system is shown in Figure 3-85.

3. System structure design and subsystem division Divide the functional modules or subsystems of the system (if there is or necessary, especially large-scale software systems).The detailed design of the system functional modules is based on the structured design method, and the functional modules or subsystems of the system are designed on the basis of the layer-by-layer decomposition of system functions.

4. The main task of the outline design is to convert the system extension use case diagram obtained from requirement analysis into software structure and data structure. The specific tasks of designing the software structure are: dividing a complex system into modules according to functions, establishing the hierarchy and call relationship of modules, determining the interfaces between modules and human-computer interfaces, etc.

Design of system permission function

Permission management is a basic function of "system-level". In general, only administrators can operate it in the system, unlike other functions that can be tried in other systems. On the other hand, the permission function cannot be operated and used by ordinary users, so the sense of existence is low, and it will not be outstanding if it is done well, but if it is not done well, it will lead to the whole process not working and the product will collapse.

Role management interface, the user defines the role and gives permissions to the role; the user role management interface, the user assigns roles to the system user. A very simple example, for example, you have opened a personal Taobao store, and there are many permission management functions on the system, such as opening upload and deletion permissions for customer service.

The director has all the authority, and the accountant and cashier have some authority. Under special circumstances, a person may have multiple positions.

Usually, we express the permissions in the application system as access to the menu (page level), the operation of functional modules (functional level), the deletion of file upload, and even whether a button on the page, whether the picture is visible, etc. belong to the category of permissions.

System function module design

UI design global functional structure module refers to important modules or function points divided according to user needs and system functions in the UI design process, which are used to build the global structure and functions of the system. Frame. Navigation module: including navigation bar, menu, etc., which is used to realize users' navigation and switching of functions and contents in the system.

I) System functional structure The basic function of the information system such as agricultural land division is to serve special land evaluation, and to realize the informatization and integration of agricultural land division and other work in combination with land management.

The detailed design of the system includes the following: system structure design and subsystem division Division of system functional modules or subsystems (if any or necessary, especially large-scale software systems).

On the other hand, the system design aims to facilitate the timely sharing of geological scientific data, and strives to provide a platform for scientific research for geological scientists. The main functions include: Internet/WEB-based map display, the development of a general map navigation operation function module, and the support of WEB-based map browsing, movement, enlargement and reduction functions.

The control range of the functional module refers to the functional module itself and the collection of all functional modules directly or indirectly subordinate to it.

According to the requirements of the agricultural land division and other achievement management information system in Guangdong Province, the system realizes the function and the logical structure between modules as shown in Table 6-4 and Figure 6-3.
