The intelligent hardware industry has always had the wisdom of the Golden Triangle of Smart Hardware: cloud services, smart hardware, and mobile applications. Smart home is also true.
The reason is that the main reason why smart homes first control the home equipment through the cloud platform is because the home network is smooth and dynamic IP address, and the dynamic IP has no fixed address. That is to say, on the public network, there is no way to access the home network.
In the smart home promotion, the equipment in the office is not connected to the home device through the mobile phone, but each time the smart home device is modified in the cloud state, the smart home device periodically checks the corresponding cloud state and changes its own according to the cloud state. status. Through the cloud state, transparent transmission between the external network and the internal network is realized.
There are natural flaws in the interaction of home devices under cloud computing.
It is precisely because cloud computing plays an important role in transparent transmission. More and more devices are using cloud computing to control devices at home. Many device interactions in home LANs are also realized through cloud computing. However, devices on the LAN that rely heavily on the cloud platform have the following problems:
â—† When there is electricity in the home, once the network fails, the home equipment is difficult to control. The home device is controlled by the mobile phone. If the mobile phone is in the local area network, the device is generally directly controlled, and the external network is transparently transmitted. The linkage between smart items, usually the linkage logic is on the cloud. When a network failure occurs, the linked device is easily out of control.
â—† Control the home equipment through the cloud, because the home equipment regularly checks the state of the cloud to realize the control of the home appliance, and the time when the device accepts the response depends on the period of the device checking the state on the cloud platform, and on the other hand, depending on the home equipment. The rate of networked networks. If both cycles are long, the response time is uncontrollable.
â—† Device linkage within the LAN, in many smart home solutions, there is no control within the LAN, so the control within the LAN is usually achieved through cloud services. In the switching speed of products such as TVs and air conditioners that do not require high speed, the user experience does not experience the difference in experience caused by the delay. However, with the popularity of smart homes, more and more lighting equipment is realized through intelligent control. With a little delay, people can immediately feel the inconsistency caused by delay.
Can edge calculation solve the pain point?
In fact, in the early IoT ecosystem, these problems have actually been planned. However, in the early stage of smart home development, enterprises and investors will focus on the big data value of cloud platforms and cloud platforms, while ignoring an important One link, the edge calculation. Figure:
When the smart home industry will focus on the service level of the IoT service platform, the function of cloud computing has been emphasized at the earliest, and the location of edge computing has been weakened into a simple communication module function. At this time, many technology enthusiasts have tried to use smart items, but smart homes have stopped at some fans and have not formed a large-scale popularity. This is mainly because the experience is not good, and the pain points of the users are not solved, but the difficulty of the users is increased.
With the increase of smart single-item categories, smart homes are increasingly focusing on scenarios, but must the scene linkage be achieved through cloud services with poor efficiency and poor experience? It is clearly the linkage within the LAN. Why do you want to pass cloud computing?
The technicians gradually realize the importance of edge computing. The linkage between devices can be realized by edge calculation in the LAN; the logic in the edge calculation has backup on the cloud; the control of the edge calculation and the control of the cloud need to be synchronized, within the device. The information also needs to be updated regularly.
With the layer of edge computing, the control of the device in the Internet of Things is similar to the control of the hand: the control of the human hand can be controlled by the brain, while the spinal nerves are also conditioned, while the spinal nerves are conditioned. Action, the brain can track.
MacBee is a protocol defined as edge computing
Therefore, in 2016, edge computing is very hot in the field of technology, and some organizations have participated in the research of edge computing, such as Huawei at the end of 2016, Shenyang Institute of Automation, Chinese Academy of Information Technology, Intel Corporation, ARM and iSoftStone. Several companies have jointly established the Edge Computing Alliance.
However, in the smart home field, there is a company that is engaged in edge computing-related attempts, but there is no edge calculation:
MacBee is a communication protocol realized by Galaxy Fengyun to solve the problem of smart home communication. While realizing the function of smart home, it helps many lighting companies realize the intelligent control problem of lighting.
In order to solve the lighting control problem, because of the delay of communication, the inconsistency of lighting changes is very obvious, so MacBee has carried out a lot of optimization in the development process, on the one hand to improve the real-time and reliable wireless communication. Sexuality and stability; on the other hand, in order to solve the delay and uncertainty caused by the network speed, it is found that there must be a gateway-like control device in the local area network to control the devices in the local area network, so as to realize the linkage of devices in the local area network. Through the network; at the same time, this device also needs to synchronize cloud control, keep the control scenarios consistent, and keep the state of the control device consistent; if the device volume is very large, it may need to have multiple gateway-like products to maintain consistent control among multiple products. Sex.
These control of the terminal equipment solves the lag uncertainty of the equipment due to the network delay, and at the same time takes into account the cooperation between the cloud computing and the terminal equipment; it can also maintain control when controlling several hundred lamps at the same time. Consistency has achieved very good results in the field of lighting control.
Although Galaxy has not defined this function as edge computing, its gateway product function solves the problem of edge computing. MacBee's technology can provide a good reference for smart home enterprises that are still exploring the field of edge computing.
