In recent years, smart home devices continue to rise. The common feature of smart homes is that they can access the Internet and then remotely control home devices through the mobile phone APP. I may say it more generally. Basically, smart homes at the elementary level are basically the same. In fact, I have always had a keen interest in smart homes, so after I checked in, my new home purchased a lot of smart home products. This time I saw the keywords of smart home in the hot week, and there is the idea of ​​writing this article. In this article, I will outline the layout of home smart devices. Although the layout of each type of house may be different, they are basically the same, and some smart home devices are subject to personal preferences, funding, and installation issues. No installation, but some of it will be covered below.
Ground floor plan
Second floor plan
The above two pictures are the planes on the first floor and the second floor of my house. The installed smart home devices are basically marked in the figure above. All entrance doors are equipped with door and window sensors, which trigger an alarm as soon as they are opened. A human sensor is installed on the stairs and an alarm is triggered when someone passes by. In the first floor and second floor, three smart cameras are installed to monitor all directions. After the dynamic alarm is turned on, as long as the screen changes, it will be pushed to the mobile phone. Taking into account privacy issues, you can set the camera to turn off after going home everyday, and then after sleeping Turn on the camera automatically. Two routers are installed in the home, and the main route is installed in the weak box at the entrance. Considering the signal problem on the second floor, this route is set at the stairway position, so that the network signals of all rooms on the first floor and the second floor are relatively stable. The smart socket has two positions, one is a kitchen kitchen that controls the kitchen, and the other is a night light that controls the main guard. Millet's air purifier is set to turn on and off at regular intervals. In the scene setting, when the AQI is below 50, it is automatically turned off. In this case, the air purifier is basically free of operation.
Basically, so much more. Others are some individual smart appliances that cannot be linked. So I think that my home smart home is just a few furry ones. I think the smart home is the key to linkage. All equipment must be linked together. Our company had done a model house a few years ago and installed Honeywell's full range of smart home devices. For example, after a user enters the elevator and brushes the ladder, the curtains at home will be automatically pulled up, and the main light of the home will be turned on. Welcome mode is on. However, this smart device must be installed when the decoration, and the cost is relatively high, the key is the late maintenance and replacement is too much trouble, the last one into the wall switch is broken, the local physical store will not have to say, even horse father's home is useless, The result was a 10 yuan ordinary switch.
Let’s talk about smart devices in my home. Let’s introduce the core members of my smart home system. It’s the Xiaomi smart home package. I’ve been spraying it since I started, and I’ve been stable since I started. With the use of really really good, this smart suit I also specifically wrote original, the following is the portal, interested can see.
Millet smart home in addition to smart gateway is a must have, there are many members below it, can be configured according to their own needs, and now Xiaomi smart home's child equipment is also more and more abundant, human sensors, door and window sensors, temperature Humidity sensors, wireless switches, Rubik's cube controllers, wall switches, smart sockets, etc. All sub-devices and smart gateways are connected via ZigBee, not Wifi, so in the state of broken network, this smart home can still interact with itself. .
Door and window sensor: This can be installed on the door or on the window. It consists of two small pieces. Once separated, the smart gateway will be linked to alarm. I installed it on the entrance door and the patio door. In the alert mode, once When the sub-master block is separated, the smart gateway will sound and light alarm, and the mobile phone will also receive the push, basically delaying for a few seconds.
Human sensor: The principle is very simple. Some people can sense it. I am installed in the stairs of my house. Stairs are the only way to go between the first floor and the second floor. Once someone invades, it will definitely pass through this position. In addition, this human sensor has many other functions. For example, you can install it under the edge of the bed and go to the toilet in the evening. You can let the night light turn on, and how big the function is.
Wireless switch: All devices connected to the smart gateway can be controlled by clicking or double-clicking. I am installed in the doorway to use one key to activate or deactivate the smart gateway's alert mode. The wireless switch can also be linked with other devices, so that non-intelligent devices can also achieve wireless control. For example, the wireless switch can be controlled with the smart socket and wireless control of the electric fan can be achieved.
Temperature and humidity sensor: can be used to view the temperature and humidity in the home, the sensor will record temperature and humidity 24 hours a day, about 1 hour or so sampling. At present, this sensor has no good use other than viewing temperature and humidity. Actually, this sensor can activate or deactivate air conditioners, dehumidifiers and other devices through changes in temperature and humidity, but currently air conditioners and dehumidifiers are available in the market. It is not a mechanical version, that is, it does not run automatically when it is powered on.
Camera: Now the camera is free to install wireless connection anyway, connected to the power access network will be able to use, of course, you have to install on the wall or need some effort. My home is equipped with a PTZ, in fact, there are some places with PTZ is also useless, specifically to see the size of the perspective range to set it. On the left side of the picture above, the small ant 2 is unable to access the millet smart home. It is a pity that the small ants are going to solo now. In fact, there are many brands of cameras available, Dahua, fluorite, millet, 360, etc., in addition to professional camera, and now the majority of Internet companies also like to participate.
Air purifier: Several air purifiers at home, also known as the home of millet, can be regarded as smart home devices. Xiaomi’s air purifier is very controversial. I believe that the majority of value-friends should understand it. The principle of cheap and good value, bought a millet air purifier 2, personal feeling effect is OK, you can set the AQI automatically shut down the air purifier when the value is lower than a certain value, and this air purifier will also automatically learn , For example, it will automatically enter sleep mode after several nights.
Smart Desk Lamp: On the picture above, this is still a millet's home. Xiaomi's things are good here. Basically, most of its homes can access the Internet and can become smart home devices either directly or indirectly. Some people may say that the desk lamp is also remotely controlled and cramps! I specifically bought this feature, although the remote console light can also be achieved through a smart socket, but this lamp is more direct control of the millet. The reason why I look at the remote control function is because this function can be anti-theft. If you go outside or if you are not at home for a while, you may find it easier to recruit thief. With this remote-controlled lamp, you can turn on the lamp every night. , creating an illusion that someone is at home, although not necessarily useful, but more or less can give the thief a bit of concern. There are also smart bulbs, millet homes, and lifesmart smart light bulbs, which are often used by valued friends. This is also very easy to use. Some models can also create a variety of ambient lighting.
Smart socket: This should have been many years ago, and now many brands have smart sockets, even the old electrical manufacturers have begun to do smart sockets, the left side of the picture is a good example of the geese, for example, the other bulls also in succession in these two years Several smart sockets have been introduced. This kind of smart socket can be used to remotely control the mechanical version. I use it on the kitchen kitchen treasure. The kitchen appliance is very expensive. It's really inconvenient to plug and pull every day, but it can't be hurt if the 24-hour electricity is not available. With a smart socket, it's just fine, as long as you set a good time to turn it on and off, Xiao Chu Po will be turned on and off every day, saving energy and convenience. The smart socket can also control the luminaire, such as a remote console light, which can realize the function of the above millet desk lamp. If it is the millet's smart socket, it can be linked with the human sensor to control the opening and closing of the night light. In fact, there are many functions of smart sockets, depending on your own creativity. Last reminder, when used in high-power electrical appliances, ordinary smart sockets are more dangerous. Please purchase smart sockets for high-power electrical appliances.
The smart body fat is called: On the left is Yunmai's smart body fat, and on the right is picooc's smart body fat. It can measure 10 items of data on the body. The most important thing is body weight and body fat. Other data are not accurate. It's hard to say, but you can only provide a rough reference. It is called a smart scale because it can connect with a mobile phone and implement all the functions on the APP. The two smart scales are much stronger than the Xiaomi family.
In fact, there are many smart home appliances can be said, of course, most of the millet home, such as electric kettles, rice cookers, floor fans, blood pressure monitors, water purifiers, etc., I will not go into details. Everyone also saw that many smart home devices are home to millet. Of course, I don’t mean to recommend Xiaomi’s stuff. Xiaomi’s stuff is good or not. You can refer to the comments of many valued friends. I think that every thing in Xiaomi’s home is in Aunt’s home. Certainly can find the corresponding original article, but one thing I think is very good, Xiaomi's home app “m family†can link the absolute majority of its home equipment, this is my most fancy, these devices have been formed In an ecosystem, many functions can be achieved through their own creativity.
Perhaps n years later, every household can implement a smart home model. This n-value should not be great!
The definition of dual frequency band refers to the characteristic that the same communication device can work in two frequency bands. For example, a dual-band router means that it can work in 2.4GHz and 5.0GHz modes at the same time. Single frequency wireless router: It can only work in 2.4GHz mode. Its applied disciplines include communication technology (first-level discipline) and mobile communication (second-level discipline)
ONU (Optical Network Unit) optical network unit, ONU is divided into active optical network unit and passive optical network unit. Generally, devices equipped with network monitoring including optical receivers, upstream optical transmitters, and multiple bridge amplifiers are called optical nodes. The PON uses a single optical fiber to connect to the OLT, and then the OLT connects to the ONU. ONU provides services such as data, IPTV (i.e. interactive network television), and voice (using IAD, i.e. Integrated Access Device), truly realizing "triple-play" applications. The ONU has two functions: it selectively receives the broadcast sent by the OLT, and responds to the OLT if the data needs to be received; collects and buffers the Ethernet data that the user needs to send, and sends it to the OLT according to the assigned sending window The end sends the buffered data. The application of ONU can effectively improve the uplink bandwidth utilization of the entire system, and it can also configure the channel bandwidth according to the network application environment and applicable service characteristics to carry as many end users as possible without affecting the communication efficiency and communication quality, and improve the network utilization Rate and reduce user costs.
