OFweek smart home network communications smart hardware industry has always been a golden triangle of intelligent hardware: cloud services, smart hardware, mobile applications. Smart homes do the same.
The reason is that the first reason that smart homes control home devices through the cloud platform is because home network patency is a dynamic IP address. Dynamic IP has no fixed address, which means that there is no way to access home networks on the public network.
The smart home propaganda equipment in the office to control the home, not through the mobile phone to connect home equipment, but each time to modify the status of smart home devices in the cloud, smart home devices to check the appropriate state of the cloud, according to the state of the cloud to change their own 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
Because of the important role of cloud computing in achieving transparent transmission, more and more devices begin to use cloud computing to control home devices. The interaction of devices in many home LANs is also achieved through cloud computing. However, over-reliance on the cloud platform in the LAN will have the following problems:
â—† When there is electricity at home, once the network fails, the home equipment is difficult to control. If the mobile phone is in the local area network, it is generally controlled directly by the device, and the external network is transparently transmitted. The linkage between smart items, usually the linkage logic is in the cloud. When a network failure occurs, linked devices can easily get out of control.
â—† Controlling home devices through the cloud, because home devices regularly check the status of the cloud to control home appliances, and the device accepts the response time, which depends on the period of the device's state check on the cloud platform. On the other hand, it depends on the home device. The speed of the network. If these two periods 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. Therefore, the control within the LAN is usually implemented through the cloud service. In the switching speeds of products such as TVs and air conditioners that do not require high speed, the user experiences no difference in experience due to delay. However, with the popularity of smart homes, more and more light equipment through intelligent control, a little delay, people can immediately feel the delay caused by inconsistency.
Can edge calculations solve pain points?
In fact, in the early days of the Internet of Things, IBM had actually planned these problems. However, early in the development of smart homes, companies and investors will focus on the value of big data on cloud platforms and cloud platforms, ignoring an important one. One of the links, edge calculations. Pictured:
When the smart home industry will focus on the level of service of the Internet of Things platform, the cloud computing function was first emphasized, and the position of edge computing was weakened into a simple communication module function. At this time, many technology enthusiasts have tried to use smart single products, but the smart home also stopped at some enthusiasts, and did not form a large-scale popularization. This is mainly because the sense of experience is not good, it does not solve the pain points of users, but it increases the user's difficulty of use.
With the increase in the number of smart single-item products, smart homes are increasingly focusing on the scenes. However, the linkage of scenes must be implemented through cloud services with poor efficiency and poor experience. Obviously is the linkage within the LAN, why should we go through cloud computing?
The technicians are gradually aware of the importance of edge computing. The linkage between devices can be achieved through edge calculation within the LAN; the logic within the edge calculations is backed up in the cloud; the control of edge calculations and the control of cloud computing need to be synchronized. The information also needs to be updated regularly.
With the edge computing layer, the control of the device by the Internet of Things is similar to the control of the hand: the control of the human hand can be controlled consciously by the brain, while the spinal nerve is also conditionally reflexed; Actions, the brain can track.
MacBee is an agreement defined as edge computing
Therefore, in 2016, edge computing was very hot in the technical field. Some organizations have participated in edge computing research. For example, Huawei at the end of 2016, Shenyang Institute of Automation, Chinese Academy of Information and Communications, Intel Corporation, ARM, and iSoftStone. A number of companies have jointly formed an edge computing alliance.
However, in the field of smart home, there is already a company that is engaged in edge computing-related attempts, but it is not called edge computing:
MacBee is a communication protocol implemented by Galaxy to solve the smart home communication problem. While realizing the smart home function, it helps many lighting companies realize the intelligent control of lighting.
In order to solve the lighting control problem, the inconsistency of the lighting changes due to the delay of communication is very obvious. Therefore, MacBee has undergone a great deal of optimization in the development process, on the one hand improving the real-time and reliable wireless communication. On the other hand, in order to solve the delay and uncertainty caused by the speed of the network, it was found that there must be a gateway-like control device in the LAN to control the devices in the LAN, so that the device linkage in the LAN cannot be implemented. Through the network; at the same time this device also needs to synchronize the cloud control to keep the control scenario consistent and maintain the same state of the control device; if the device volume is very large, multiple gateway-like products may be required to maintain the consistency of control among multiple products. Sex.
The control of terminal equipment on the one hand solves the lagging uncertainty caused by the delay of the network due to network delays, taking into account the cooperation between cloud computing and terminal equipment, and maintaining control when controlling hundreds of lights at the same time. The consistency has achieved very good results in the field of lighting control.
Although the Galaxy Storm did not define this function as edge computing, the function of its gateway product solved the problem of edge computing. MacBee's technology can provide a good reference for smart home companies that are still pursuing edge computing.
