The current status of the smart home
Each for their own: large and small manufacturers are competing in the division of the entire market, the larger platform nature of the Mijia, Ali Intelligence, Beijing fish intelligence (Jingdong), easy micro-connections and so on, including some of the big manufacturers of the United States, Haier, Huawei, and other companies are also actively laying out the status quo is extremely chaotic, every manufacturer of smart devices have to be installed with an APP resulting in the user's learning costs It's a very high cost of learning for the user.
The protocol is not unified: the equipment between the manufacturers can not be interconnected and difficult to link, and compete to be the boss of each other to create technical barriers. Perhaps in the future, after several rounds of competition, the strongest big brother will sit down together to negotiate the rules of the game, develop and publish industry communication protocol standards.
Smart home mainstream communication mode (nerve)
1. WIFI: popularity of the absolute advantage of networking without additional costs, the current mainstream way. But itself is flawed, power consumption, network nodes are limited, more equipment will seriously drag the entire network. the emergence of WiFi6 will have some improvement, the equipment has been put on the market to be popularized.
2. ZigBee: This technology is born for the Internet of Things, low-power network capacity, self-organizing network is the biggest technical highlights. Although the industry recognizes ZigBee, but there is no large-scale application, the ecological aspects are not very perfect.
3. Bluetooth: This technology always appears in the smart home field discussion, in fact, the application is very little, only in part of the smart locks, smart speakers, smart lights have applications. Bluetooth still has some potential after all, the popularity of Bluetooth and WIFI is not similar.
4. NB-IoT: a newcomer to the cellular network, 5G may push this technology to the peak, personally I think it is not very suitable for smart home use, unattended devices, industrial control collection is quite suitable.
5. wired: customized design smart home using this approach is the best basic program, safe and stable without interference, if coupled with similar POE technology, wireless communication as a complementary perfect Ha!
Smart home gateway industry status quo and possible development trend (brain)
1. Independent gateway: an independent device only gateway function, the current mainstream. Above the integrated network port, WiFi Bluetooth ZigBee and other hardware devices heterogeneous network, there is a miniature system is all kinds of smart home equipment communication and control center.
2. Smart speakers: is also the current mainstream, although it is a pickup sound device, but the cloud has a super brain, intelligent voice recognition to really free your hands, is sometimes a little retarded. Speaker and gateway combination is a good choice. Looking forward to voice recognition can be further strengthened to make it more intelligent.
3. Visual doorbell: customized smart home in the gateway and the combination of this, without the need to add additional equipment, there is a touch screen can be displayed, the operation of a stronger independence, customized smart home is suitable for this approach.
4. router: comes with a miniature system has a certain amount of arithmetic, itself is the hub of the network, such as the combination of Bluetooth ZigBee and other hardware can be called the best gateway, at present it seems that there will be no gateway and router combination products, only part of the smart router with some smart device management plug-ins. 17 years of Ali is a release of a Tmall M1 router equipped with Bluetooth 5.0, but in the end, not to be done!
5. Smart screen: essentially a TV set, itself has a strong arithmetic is also a potential object to become a gateway, Huawei put forward the corresponding concept, I do not know whether it can once again lead a wave of trends like smart speakers, seems to be enough, this play segment is too high. Smart office may have a certain market.
Smart home all kinds of intelligent sensor controllers and devices (body)
In the impression that the smart socket is the most beginning and popularity of one of the most widely used products. Later on, all kinds of products such as mushrooming stacked in the whole market. Various devices can be generally divided into three categories, sensors, controllers, household appliances.
1. Sensors: These devices provide perception for the smart home system, mainly temperature and humidity, sound, smoke, gas, liquid, door magnetism, infrared, photoelectricity, camera, etc., in addition to the camera outside the sensor itself is not too much to do, the function is also very single, to be concerned about these devices how to do the delicate and small and sensitive.
2. Controller: smart socket, smart switch, smart door locks, smart valves, smart curtains, etc. These devices only as the implementation of the expression of the intelligent scene planning for the implementation of certain requirements, which can have a lot of play, the focus is on the implementation of the mind.
3. household appliances: the market is the most chaotic is this piece, different manufacturers of different platforms different APP, small to soybean milk machine rice cooker to refrigerator and washing machine, to say that the practical value, afraid of air conditioning water heater, this part of the market is not good to control, the electrical appliances have their own ideas, the design level is also uneven. Enlightened manufacturers should open the interface of their own devices.
Smart home scenarios device linkage (soul)
At present, although the agreement is not yet unified, but the entire market has a relatively perfect ecological chain, intelligent voice recognition will be the smart home to a round of a new climax, the scenarios and device linkage is the current smart home of the biggest flower head. A well-designed and perfect program can avoid the smart home becoming a retard. Deployment of smart home in roughly three ways, there are high-end customization, personal DIY players, equipment manufacturers of complete sets of programs. To realize a perfect smart home system, from the time of house decoration should consider the device selection scenario mode device linkage program. One thousand readers have a thousand Hamlet linkage program will be roughly the same, the service provider exhaustive program to the user to self-help selection can be, who is who do the main Ha. This piece of personal belief that the realization of the principle is to reveal in the complexity of the simple, do not refuse to fancy but can not be too much trouble.
Speculations on the future of the smart home industry
1. The emergence of standard communication protocols, all manufacturers of equipment can be interconnected.
2. The emergence of the operating system and the combination of AI will be truly intelligent.
3. The emergence of a dedicated signal power line, removing the single device transformer module is more energy efficient and compact.
Smart home is only a tiny microcosm of the Internet of Things, smart community, smart office, smart city, smart health care and other intelligent Internet of Things are flourishing with vigor. The IoT is also integrating big data, cloud computing, AI, 5G and other corresponding technologies to change our lives. It is an industry that needs innovation to be revitalized.
