If you do not install smart homes in your home decoration, it will be really outdated. Maybe your friends and relatives will jokingly call them “old-fashioned”. How can we spend as little money as possible to install smart homes with high-tech content scientifically and rationally? It makes many families have a lot of brainpower. To this end, this article will elaborate on the solution of wireless smart home with three rooms and two halls for readers.
1. Program overview
This solution through the intelligent control of residential lighting, curtains, induction, background music, and access control systems, through the bright and dark matching of different lighting circuits in different rooms, forms different remote control lighting scenes, creating a comfortable and elegant environment atmosphere, and enriching people’s different Residential needs; at the same time, through the creation of different lighting environments, the beautiful melody of background music and the intelligent control of curtains, the occupants’ elegant artistic accomplishment and extraordinary character quality are brought out. Users can use the handheld remote control to change the lights, curtains, etc. at any time, so that people can relax in the leisure area, and change at any time according to people’s needs, creating a warm, romantic, and elegant environment.
2. Principles of Scheme Design
1) Practicality
What does the smart home do? In fact, it is to provide people with a safe, comfortable, efficient and convenient living environment. For smart home products, the most important thing is practicality. Throw away those flashy, just appearance functions, and the products are mainly easy to use, practical and user-friendly. Therefore, the user experience must be fully considered when designing the smart home, and the convenience and intuitiveness of the operation must be paid great attention to. It is best to use a graphical control interface to make the operation what you see is what you get.
2) Reliability
The reliability, safety and fault tolerance of the system must be highly valued. For each subsystem, take corresponding fault-tolerant measures in terms of system backup and power supply to ensure the normal and safe use of the system. Moreover, the quality and performance are good, and it has the ability to cope with various complex environmental changes.
3) Convenience
Product installation must be convenient. If wiring is required, the wall will be smashed, which is very troublesome, because the equipment is relatively fixed and cannot be moved much. Product upgrades and maintenance are also inconvenient due to the need to reopen the walls. Therefore, when choosing smart home products, it is best to focus on wireless smart homes that do not go through walls.
4) Standard
The design of the scheme should be carried out in accordance with the relevant national and regional standards, and the scalability and scalability of the system must be ensured. The standard TCP/IP protocol network technology is used in the system transmission to ensure that the system is compatible between different manufacturers And interconnection.
3. Wireless smart home occupies the mainstream position in the market
Wired smart homes were born in the United States in the 1980s, and spread to China in the late 1990s. However, due to the low level of intelligence, high prices, and inadequate after-sales service, consumers’ enthusiasm was seriously dampened, especially unbearable. What I endure is that many smart homes require dense wiring. The walls are cut to lay out the lines. The thread ends are hanging outside the wall, which is not beautiful, and cannot be updated and upgraded. Failures cannot be diagnosed in time during maintenance. Consumers have repeatedly complained. , The market recognition is low.
Currently, there are mainly three types of wireless communication technologies that are more popular in the market, namely Bluetooth, WIFI and ZigBee. The poor automatic networking performance of Bluetooth and WIFI limits its application in smart homes. For example, the Bluetooth network terminal corresponds to a maximum of 8 ports, the WIFI commercial network terminal corresponds to a maximum of 20-30 ports, and the home network terminal corresponds to a maximum of 10 ports. If a 30-port home automation system is established, 3 networks are required. Paragraph, obviously the cost is too high.
In contrast, ZigBee gateways can connect to ports without limitation and embed a variety of devices, and the superiority of its expansion performance is thoroughly demonstrated. ZigBee is a short-distance, low-cost, low-complexity, low-power, low-data-rate, two-way wireless communication technology that can be embedded in various devices and supports geographic positioning functions. Compared with other wireless communication technologies, ZigBee technology has the characteristics of ultra-low power consumption, low cost, and strong scalability. It is suitable for carrying services with small data traffic and suitable for use in places with small data traffic such as homes.
IOT Sensing launched a new generation of wireless smart home based on ZigBee, which has obvious technical advantages, easy installation, no need to break the wall wiring, and those with junior high school education can assemble and install by themselves; automatic networking, freely embedded in various devices, and strong expansion performance ; After-sales service is fast and thoughtful, able to detect faults quickly and accurately and repair them; the cost is low, the power consumption is not high, and it is fully in line withmodernThe family’s pursuit of a green life.
4. Specific solutions for smart home with three bedrooms and two halls
The ZigBee wireless smart home system launched by IOT Sensing includes multiple subsystems such as smart lighting, smart security, environmental control, smart home appliances, smart curtains, and audio-visual control. The following briefly describes the functions of several subsystems:
A. Intelligent lighting system
A1 dimming soft start function
When the light is turned on, the light slowly turns on, and when the light is turned off, the light slowly dims and then goes out. This romantic process protects your eyes from sudden changes in light, and greatly extends the life of the light. The brightness of the light can be adjusted at will, even if the brightness of the light is modulated to the firefly state, the light will not flicker. The soft start function of the light can memorize the last light brightness level.
A2 Timing function
You can perform timing functions on indoor and outdoor lighting systems. While saving energy for you in the control mode, it can also make you feel the humanization of the home lighting system. If you are out for a long time, you can set it up at night to automatically turn on and off the lights in your home, which can act as a warning.
A3 scene function
The changing combination of various (groups) lights can create a harmonious atmosphere and romantic mood at different moments. Through the wiring and setting of the intelligent lighting system, you can easily combine different scene modes according to your preferences. And these scenes can be stored and opened in “one-click” mode. The respective state and brightness of each lamp in different scenes can be set and memorized, and the complex lighting effects are instantly presented with just one touch when using it. In the scene function, the lighting can also be combined with other equipment (such as curtains, curtains, TV/audio, etc.) to form a complex scene. Such as meeting guests, reading, listening to music, dinner mode, theater mode and so on.
B Security Control System
B1 Perimeter prevention
B11 Infrared to the radio
Install infrared beam fences around the villa. In the fortified state, if there is any illegal entry, the alarm system will be activated. The advanced infrared beam fence adopts a humanized design, and the angle of the transmitter and receiver can be rotated at will. Perfect anti-disassembly, anti-cutting, anti-short circuit, anti-pet functions, etc., greatly enhance the ability to prevent false alarms. Even if people crawl through or cross over, the system will never fail to report. The infrared fence will guard the first post for your family safety.
B12 video surveillance
Multiple video surveillance points can be installed on the periphery and inside of the house, so that no matter where the owner is, all the things that happen in the home within 24 hours a day can be seen through the convenient Internet. When you are away for a long time, it can record everything that happened within 30 days × 24 hours at home, and you can replay them one by one after you get home. Even when you are away from home, it can send relevant captured images to your mailbox and mobile phone regularly and quantitatively. When there is an abnormal situation in the home, the video surveillance system can also automatically call the police.
B2 Indoor Security
B21 Fire protection
Install smoke detectors and gas detectors in cloakrooms, kitchens and restaurants. When there is a smoke or gas leak, the system will immediately ring the alarm. When the waiting time for the ring reaches your preset value, it will automatically call the alarm .
If the danger is due to a gas leak, if a gas robot is installed in the gas supply system, the gas valve can be automatically closed.
B22 Door/window break-in induction alarm
When the home security equipment is armed, if the doors and windows are illegally damaged and break in, the system will immediately ring the alarm, and when the waiting time for the ring brings you to the preset value, it will automatically dial the alarm.
B23 motion detection
When the motion monitoring function is turned on, any moving objects that enter the range of the motion detector will be monitored. The mobile monitoring system has the function of identifying small moving objects such as pets, which can effectively prevent false alarms and omissions. In the event of an emergency, the system will immediately ring the alarm, and when the waiting time for the ring reaches your preset value, it will automatically dial the alarm.
C Environmental Control System
