the establishment of an instry standard also needs the following two conditions:
first, practical, efficient and feasible technical standards: the graal establishment of cloud services, Internet of things and IPv6, which makes the technical standards clear, but also has a lot of uncertainty
Second, enough instry influence: at this stage, most of the smart home solutions and procts manufacturers still stay in the physical control layer, and no one has enough instry influence
so now there is no standard for smart home, but the emergence of this standard will be inevitable
at this stage, ZigBee and Z-Wave are the two most representative technical standards for smart home control system standards. ZigBee protocol starts from the architecture of Internet of things, and Z-Wave is specially customized for smart home. However, the enterprises using these standards are still in the early stage of development e to the limitations of peripheral facilities, cost and technical perfection. Throughout the market, smart home procts are still in the primary stage of physical control, and there is no obvious connection between informatization, cloud services and Internet of things
the development of domestic smart home system is also very rapid in recent years, almost following the pace of international development. Haier and others in the early stage also have great changes after the first round of shuffling. Now the domestic smart home technology is dominated by rf315, 433 radio frequency 2262.1527 standard protocol, which has low threshold and low development cost, In the early stage of the development of the market has played a very good role in promoting, and with the maturity of the market, the defects of technology graally exposed, those who did not make technological transformation of the company are dismal
after the first round of reshuffle, some new technologies have emerged, with 2.4G and 433 carriers as the most representative. In terms of protocol composition, ZigBee networking technology has great advantages in terms of cost, and adheres to the development of cloud service architecture. Voice control function makes the control from physical control to content control, It has achieved effective integration with Internet of things and cloud services
in terms of market promotion, the OEM scheme is adopted to accelerate the market share of smart home. From these two points, it is not difficult to see that Shenfu smart company is also going to the standard. Through market feedback, the integrity of the agreement can be continuously improved, and the development risk of other smart home brands can be reced by means of technology, so as to obtain the market share. The direction is right, The method is good, but I don't know how far I can go
although there is no standard for smart home for the time being, with the graal maturity of the market, after several rounds of market adjustment and reshuffle, the technology used by the companies standing in the market will be the standard. The author thinks that the market standard can never be discussed by a group of experts, and it must be eliminated through the baptism of the market. I hope that in the future, the establishment of international standards will be the basis for the development of smart home, We can see the figure of Chinese enterprises

Wireless cable bus, I read the article to share with you
the first part, communication control strategy selection
at present, smart home, as a popular branch of the Internet of things, has begun to walk into the families of ordinary people. As an ordinary user who has only just contacted or not contacted deeply, how to use it in all kinds of crazy smart home advertising, It is a headache to choose the appropriate smart home solution in the smart home life scenes rendered by various large companies
the current common communication technology solutions can be classified into wired solutions (transmitting control signals through wired media) and wireless solutions (transmitting wireless signals through radio waves) in terms of realizing control communication technology solutions
common wired control schemes are divided into RS485 bus, can bus, KNX bus, IO direct control (signal transmission through the on-off of the line nodes))
common wireless control schemes are divided into medium and short distance ZGB, zwave, 315 / 433 / 2.4G, non networking bidirectional, 315 / 433ask, WiFi, long distance Lora, Nbiot (with communication charge))
reliability analysis of two classification schemes
wired & gt; Wireless
because the wired signal transmission is through the physical medium, the vibration of the voltage changes to transmit information, in the case of line wiring specification, the external interference is very small, in the direction of reliability, the wireless is subject to the transmission distance, electromagnetic environment within the transmission range, communication network delay and other factors, there is the situation that the control information can not be transmitted to the controlled equipment. The most intuitive example is that people use the landline to call the landline, the voice is very clear, but when they use the mobile phone to call the mobile phone, or when the landline calls the mobile phone, sometimes the communication is intermittent. So wired is more reliable than wireless
in wired control scheme: IO direct control & gt; Bus
IO direct control is directly input to the control system or embedded MCU through on-off signal, without any data molation, conversion, on is on, off is off, MCU can get on-off signal very clearly and clearly, so as to make executive response, almost no delay occurs in real time
all kinds of bus communication is to transform the information to be transferred into standard bus level signal through special communication protocol chip, and transfer the information through a certain frequency of level signal vibration. There are two links in the middle: information program processing conversion and level conversion. The two methods have their own advantages and disadvantages. In the existing wired control schemes, the two methods are generally combined. IO direct control is stable and reliable, but the transmitted command data is wired, and the two lines can only transmit 0 / 1. People can understand the telegram. The bus is stable and reliable, but the two lines can transmit all kinds of control commands, which can be understood as a telephone line that can transmit any information
in the wireless control scheme: nbiot & gt; Lora > wifi > zgb/ zwave > 315 / 433 / 2.4G non networking bidirectional & gt; 315 / 433ask
nbiot is based on the mobile network of operators. In theory, it can be connected and controlled where there is a signal. However, e to the high price of the mole and the need to pay for the communication expenses of operators, it can not be widely used with families, but in bike sharing, smart meter, smart charging pile... It is widely used in many scattered commercial projects
Lora is also a very hot wireless communication technology recently, which combines the advantages of two-way communication, strong wireless anti-interference ability, automatic frequency molation to avoid congestion, long communication distance, and communication after power on. It is sure that there will be more and more applications in smart home in the future, and the development at this stage is also constrained by the expensive mole cost and large volume, Network encryption communication system is not perfect and other factors have not been applied on a large scale
With the participation of major chip manufacturers, WiFi is now very cheap and can be called cheap. It took less than two years from tens of yuan to a few yuan now, and it has been widely used in all kinds of intelligent procts. However, e to routing networking, network delay and other reasons, large-scale application in big house still has its limitations. For example, after power failure and incoming call, it needs to wait for its connection network to be controlled, and a scenario execution may be inconsistentZGB / zwave, as an old short-range ad hoc network wireless communication protocol, is very popular in the wireless communication scheme a few years ago. Now it has been graally marginalized e to the impact of WiFi. From the perspective of the people who designed this set of communication rules at that time, ad hoc network is a very good way and far sighted, but short-range restricts its development, It is a great experience for network deployment. You should at least have a standby node within its communication range. Otherwise, once the key node fails, the control equipment through the key node will be out of control. At the same time, because the network needs time, it can not be powered on immediately. Suitable for small house control, once the house is large, the delay will be very obvious
315 / 433 / 2.4G non networking two-way, this is equivalent to that the major manufacturers are free to play more, there is no unified standard and protocol, point-to-point, point to many, or many to many all depend on the manufacturer's background settings matching, because there is no standard networking rules protocol, the stability and reliability of this depends on the manufacturer's basic skills. Short communication distance is not suitable for large house applications
315 / 433ask, which mainly transmits 2262 and 1527 coded wireless signals, is a widely used short-range wireless communication protocol in the world, without the feeling of networking, with direct signal, simple control, mature moles and controllable cost, and is widely used in large-scale applications. There are thousands of moles on Taobao that can be freely combined and expanded very flexibly, The disadvantage is that there is no feedback
If you have a big house, you can choose wired controlif the house is too small and the real-time control reliability is not required, the wireless scheme can be selected
personally, as far as home control is concerned, after all, these are high-frequency devices. In the early stage of the wired scheme, there is one more link in the wiring, but in the later stage, it will be very easy to recommend the scheme with wired as the main part and wireless as the auxiliary part. If there is any omission in the wiring, use wireless to make up for it
the second part, networking control strategy selection
smart home as an important part of the Internet of things, networking control has been used as a basic standard control mode. Now you should be surrounded by all kinds of cloud controlled advertising. Have you heard about all kinds of big data and intelligent AI marketing? Do you think these concepts are high-end and avant-garde
what is cloud control and big data
to put it simply, when does your wife go home, when does your child go home, whether the gas valve is on, and whether the sensor detects that you have been to the bathroom several times, and whether there is anyone at home now... The information is first transmitted to the business server through the smart device at home, and then your mobile phone connects to the business server through the account and password. The business server pushes the relevant data to you, so that you know the status of your home. You can control and operate the equipment at home through your mobile phone, and control the smart device at home through the business server, This is cloud control. Mobile & lt-& gt; Merchant server & lt-& gt; Smart devices at home
the control data of eating and drinking Lhasa is big data
According to statistics, you go to the toilet at 7 o'clock every day for several months. AI may think that you go to the toilet at 7 o'clock every day, and then suddenly turn on the toilet light automatically at 7 o'clock every day. However, you want to sleep in today.... This is AIfrom the perspective of open Internet of things cloud platform providers:
now there are many free logistics network cloud platforms, the ecology of Xiaomi, the ecology of Jingdong, the ecology of Ali.... Everyone's idea is to let smart home or home appliance manufacturers hang up all the devices and realize the management and control of all the devices in the cloud. Now many basic services are free, just like Taobao was free at the beginning, but the follow-up is not clear. This is a very smart profit model for cloud businesses. They don't need to spend a lot of energy to develop a variety of hardware devices. They only need software platforms to integrate various hardware resources to create wealth. At the same time, they can extract greater business value through big data analysis of various data uploaded by various devices and user usage habits
from the perspective of smart home or home appliance manufacturers:
I don't have the energy or technology to build a cloud platform. If I have a free one, it's just easy. I can also advertise my own cloud. I feel it's advanced if I have a cloud. At the same time, it can collect user data, which can help you get more at one stroke
I don't know if you've noticed that there is a user's perspective missing in this link. The above two interest groups regard the users or the devices purchased by users and, more specifically, the various data generated by the devices purchased by users as a resource to provide services for big data analysis or larger layout. At the expense of the user's ego, the platform business's ego is achieved
from the user's point of view:
1, am I willing to hand over all kinds of devices in my home to the platform provider for management? After choosing the platform, you don't have to choose. Open your mobile control app and see the privacy agreement that the manufacturer has prepared for you. You can choose not to use it. I will collect your data when I use it
2, do all the devices at home feel safe in the cloud? It doesn't matter when there are only one or two sockets in your home, but when all the household appliances, detectors, power data and video data in your home are in the cloud, even if they are very safe, there is no sense of security
3, what if the platform provider's service is down and the device is hacked? When all the devices are regularly connected to the platform, the data of these laws can be analyzed in the background of the platform, which is more attractive to hackers or people with bad intentions. Think about making millions of families turn off the TV and water valves at the same time, and the sensational effect and influence can definitely make the headlines
4, I just want to know my data, OK? Now all kinds of channels and software are full of means of user data collection. Choosing cloud is equivalent to uploading all the data of your family's operation status. Both platform providers and other businesses will guarantee not to disclose user data, and will say that customers are the first, but the data will certainly be used by platform providers or businesses for analysis. It depends on how you feel
as an ordinary user's basic needs:
1, can safely control their own home equipment
2, I don't want to upload or leak my control data to ensure my privacy
is there a good plan for you to choose
as a technology enthusiast, the answer is yes! Dynamic domain name port forwarding
port data forwarding working principle: only forwarding, not storage. Dynamic domain name provider service equipment can be said to be a variety of strange, of course, the forwarding data is also a variety, in the dynamic domain name provider instant forwarding in the chaotic, irregular data sea

you can download a driver life, professional driver,
bring your own detection update, and download the appropriate graphics card driver.
Select "graphics card". By default, the driver selects the graphics card mode. Selecting the graphics card means that the graphics card is mainly used for playing games
as for the choice of "computing", which is an optional option for AMD drivers to provide to miners, the general home graphics card is definitely used to play games and audio-visual entertainment, so you can choose the "graphics card" mode. If you choose the "computing" mode, the mining ability of general computing will be enhanced, but the game performance will decline
working principle of GPU:
GPU can support T & amp from hardware; L (transform and lighting), because T & amp; L is an important part of 3D rendering, its role is to calculate the 3D position of polygons and deal with dynamic light effects, also known as "geometric processing"
a good T & amp; L unit, can provide detailed 3D objects and advanced light effects; But in most PCs, T & amp; Most of L's operations are handled by the CPU (this is called software T & amp; 50) In addition to T & amp; Besides, we also need to do non 3D graphics processing such as memory management and input response
therefore, in the actual operation, the performance will be greatly reced, and the graphics card often waits for CPU data, and its operation speed is far behind the requirements of today's complex 3D games. Even if the working frequency of CPU exceeds 1GHz or higher, it will not help much. Because this is a problem caused by the design of PC itself, it has nothing to do with the speed of CPU
