Guide: The electrical control adopts the weak electric control method, which is safe and intelligent. It can be intelligently controlled by TV, air conditioner, water dispenser, socket, floor heating, projector, fresh air system, etc. with various intelligent control methods such as remote control and timing. control.
Smart home is the home interconnection that is finally realized by the Internet. It connects various devices in the home and provides various functions and means such as home appliance control, lighting control, curtain control, anti-theft alarm, environmental monitoring, and three-table copy. Build an efficient intelligent management system for residential facilities and family schedules, improve home safety, convenience, comfort, and artistry, and achieve an environmentally friendly and energy-saving living environment.
Smart home performance requirements
1. Software is hardware independent
The communication protocols and methods of smart home appliances are various and have not formed a relatively uniform standard. Intelligent systems must be able to shield these differences through relevant technical measures in order to achieve efficient construction of intelligent systems.
2. Customizable
The customer facing the intelligent system is an individual, so the software platform of the intelligent system, especially the human-computer communication, must be highly customizable. The secondary developers can customize the intelligent appliance management and control platform with different personalization and style.
3. Highly scalable
Since each smart home has different requirements for smart home appliances, this requires that the intelligent control system can modularly combine various home appliances according to the needs of the family, and realize seamless cooperation between the intelligent system and the hardware.
4. Many-to-many control
The intelligent system must be able to achieve the exact same control functions in any place, such as the same control functions in the living room and master bedroom.
Intelligent home system function analysis
Lighting system
To realize the intelligent management of the whole house lighting, you can use the remote control and other intelligent control methods to realize the remote control switch, dimming, full-opening and “one-off, cinema†and other one-button lighting scene effects. Implementation. It can be realized by various control methods such as timing control, telephone remote control and mobile phone control, so as to achieve the functions of energy saving, environmental protection, comfort and convenience of intelligent lighting .
On the other hand, combined with the curtain automatic control system, the indoor automatic dimming is realized, and the window is automatically switched according to the outdoor weather conditions.
(1) Control: local control, multi-point control, remote control, regional control, etc.;
(2) Safety: The control circuit is separated from the load circuit by weak current control of the high-power mode;
(3) Simple: The intelligent lighting control system adopts modular structure design, which is simple and flexible, and easy to install;
(4) Flexibility: According to the different needs of users, it is only necessary to make software modification settings to realize the change of lighting layout and function expansion.
2 electrical control system
The electrical control adopts weak current control and strong electric mode, which is safe and intelligent. It can realize intelligent control of TV, air conditioner, water dispenser, socket, floor heating, projector, fresh air system, etc. at home with various intelligent control methods such as remote control and timing.
The system can make the home video library in the living room, dining room, bedroom and other rooms, and can choose the sound source of your choice through the remote control. Avoid repeated heating of the water dispenser at night to affect the water quality, disconnect the power supply when the vehicle is out, and avoid the safety hazard caused by the heating of the appliance. Timely or remote control of the air-conditioning floor heating allows you to enjoy the comfortable temperature and fresh air immediately after arriving home.
(1) Convenience: mobile phone control, local control, scene control, remote control, remote control of telephone computer, etc.;
(2) Control: through infrared or protocol signal control mode, safe and convenient without interference;
(3) Health: Through the intelligent detector, it can detect the temperature, humidity and brightness of the home and drive the electrical equipment to work automatically;
(4) Safety: The system can automatically turn the circuit on or off according to the pace of life to avoid unnecessary waste and fire caused by electrical aging.
3. Security monitoring system
With the upgrading of people's living environment, people pay more and more attention to their personal safety and property safety, and put forward higher requirements for the safety of people, families and residential communities. Intelligent security has become the current development trend.
The security access control system realizes illegal door alarm through RFID, and the remote switch door function, together with the video monitoring system, allows users to check the situation at home from time to time, and fully realize the real-time and initiative of monitoring. In order to analyze, track, and discriminate the monitored objects in real time, and prompt and report when abnormal events occur, the “intelligence†of the security monitoring system is particularly important.
(1) Safety: The security system can detect and notify the owner in advance of stranger invasion, gas leakage, fire, etc.
(2) Simple: the operation is very simple and can be armed or disarmed by mobile phone or door controller;
(3) Practical: The video surveillance system can effectively prevent the thief from further action by relying on the camera installed outdoors, and can also provide evidence to the police after the evidence is obtained.
4. Scene Customization System
When people go home, they hope that the air conditioner in the home will be opened first, the curtains will open automatically, the bath water will be put on, the comfortable music will be opened, and so on, and each user will have different settings according to the family situation. Therefore, the Zhizhi IoT provides a custom scene system. People can package it into a “home mode†according to their own preferences. Users can complete their own set actions with one click confirmation. The more common modes are: “Back Home mode, "away mode", "sleep mode".
(1) Security: Since the scene system is confirmed, many actions will be initiated, so the operating system of each mode requires the user to confirm again;
(2) Convenience: Only one button is needed to start the pre-setting at the same time;
(3) Flexibility: Users can easily customize the action composition and set it into a smart home system of their own personality.
Resistor (Resistor) commonly known as resistance directly in our daily life.It is a current limiting element. When the resistance is connected to the circuit, the resistance value of the resistor is fixed, usually two pins.Fixed resistors are those whose resistances cannot be changed.Resistance variable is called potentiometer or variable resistor.The ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage.Variable resistor for partial pressure.On the exposed resistor body, one or two movable metal contacts are pressed tightly.The contact position determines the resistance between any end of the resistance body and the contact.
