How to write the overall design flow of the system? Do you have a template? For example, the overall system design process in intelligent furniture. Urgent need! ! ask for advice ...

First, the overall design ideas

The whole system is planned and designed with the design idea of "hierarchical, structured and modular", so that all smart home systems can be seamlessly combined to become a complete big smart home system.

Hierarchical design: In the whole system design, the system is divided into multiple levels. After the interrelationships and technical interfaces of each level are defined, the functions and system selection of each level are designed respectively, so as to ensure that only the local functions of a certain level need to be transformed in the future system transformation.

Structuring: In the structure of smart home system, the subsystems cooperate with each other to form a complete large system, which is relatively independent and self-contained.

Modularization: in the detailed design of each subsystem, follow the modular design idea and modularize the functions as much as possible, so as to facilitate the expansion and upgrade of each system in the future, and also facilitate the shielding of local faults and the maintenance and management of the system.

Second, the community computer network integrated platform

major function

(1) Provide support for the hardware platform, system software platform and database platform needed to support the intranet of the community intelligent system.

(2) Provide remote access to various interfaces (browser mode, WAP mode, telephone voice mode) to establish channels for users in the community to access the Internet.

(3) Providing the basic service functions possessed by ordinary ISP.

Thirdly, the integrated platform and system of home intelligence system.

3. 1 main functions

(1) telephone network: set up a small telephone program control system at home.

(2) TV network: establish a home TV network system.

(3) Computer network and home control system: establish home computer network system; Establish a comprehensive family control system

Four, the various subsystems of community and community service

4. 1 subsystem

Each subsystem of the community should be relatively independent, and at the same time, each subsystem should be organically connected with the supporting management unit and service unit of the community. The relationship between them includes: data and information sharing; Multimedia image signal enjoyment, etc.

4.2 Community service

Community services include online services provided by internal service units and network application services provided by community network centers;

service unit

Online shopping club booking housekeeping service online ordering property inquiry, complaint, maintenance service, etc.

Other services

Users can use a computer anywhere at home and abroad, touch the interface icon, remotely monitor and monitor the start and stop of household appliances, the lifting and protection of family safety, the amount and cost of three meters, the switch of lights and the brightness level control, and remotely monitor whether there are fire and theft alarms and the running status of household appliances. At the same time, the same purpose can be achieved by telephone and WAP mobile phone. In addition, the wireless remote control system can also be used to remotely control the switches of household appliances and lights, as well as home security. Wireless city's application system allows users to enjoy more convenient, more direct and richer services by integrating various new technologies.

Verb (abbreviation of verb) application scenario

The following describes the life scene of a future networked family.

Outdoor lights can be automatically turned off within a set time. When residents go out, the security program can be set to "leave" mode. The control system automatically turns off unnecessary lights and dangerous equipment; The thermostat automatically adjusts to save energy; If it is sunny, the system will automatically irrigate the lawn.

Residents call the control system at home, and the control system informs residents that the children will come home at four o'clock in the afternoon. They enter the correct door opening number and turn on the dishwasher.

When residents return home, the lane sensor automatically lights up 100%, the garage door opens, the lights in the garage turn on, and the lights turn off after five minutes.

When residents enter the research, the control system automatically connects the computer to the Internet. When residents choose the "Entertainment" button, the control system closes the blinds, the lights dim and the screen starts to play movies.

When falling asleep, the resident presses the "Sleep" mode key, and the power of the whole room is turned off and locked.

When residents go out on vacation, turn on the safety alarm device.

Residents send signals to the home control system through the computer in the hotel intranet to confirm that the room is in a "vacation" state and everything is normal; It's getting dark, and the music, TV and lights at home are as usual, just like someone is at home. People's requirements for the future networked family environment are: safety, comfort, relaxation, convenience, energy saving and arbitrary.
