At the IoT Developers Conference, Chen Xiongji, Marketing Manager of MCU & Wireless, Asia Pacific, Silicon Labs, discussed the development and trends of the smart home industry. After analyzing the various challenges and solutions faced by the smart home in terms of system performance, ease of use, cost and effectiveness, the Thread technical standard officially launched in June this year was introduced to the audience.
In introducing the challenges faced by smart homes, Chen Xiongji first talked about the system performance requirements, such as system response delay and the reliability of all-weather operation. The key to solving these challenges lies in the excellent computing power of the device. To ensure very low power consumption of the system. Complex installation procedures and different data lines and power lines require the simplification of system procedures and the reduction of wired connections. To this end, Silicon Labs not only offers a variety of high-performance, low-power MCUs, but also a variety of wireless transmission standards including WiFi, Zigbee, Bluetooth and Sub-G Hertz.
In addition to this, Chen Xiongji focused on the details of the latest Thread standard, including the Thread standard jointly launched by big companies such as Google, Samsung and Silicon Labs, which is aimed at the new wireless under the demand of smart home automation. Connection method. The Thread standard is shown in the figure below. Based on the IEEE 802.15.4 MAC layer and the physical layer standard, it is re-defined at the transport layer and the network layer. This means that the standard can inherit the many advantages of Zigbee and solve the Zigbee standard. Insufficient connection to the IP network directly. In particular, Chen Xiongji said that WiFi communication needs to be connected to the home gateway, and the data transmission rate is sufficient but the power consumption is too high, which is not suitable for the networking of all devices in the entire smart home , and the Thread standard can directly cooperate with the IP protocol. The entire Internet and the cloud communicate, so that the system is more reliable and secure, without worrying about the adverse effects of the gateway being attacked. The Thread standard is based on the IP protocol but can implement address sharing. Its address can also consume less resources than IPv6. The entire network can support up to 250 nodes. However, Thread can support IP-based application layer, but it will not be limited. If you choose to not use IP service, the application layer will need some transformation/adaptation.
What's more, the implementation of the Thread standard does not require special hardware. Chen Xiongji introduced that because the physical layer is based on the same protocol, it is now only necessary to make simple changes on the original Zigbee products. Support for the new Thread protocol, which means that the Thread standard has a better hardware support basis. Of course, to upgrade Zigbee to Thread, the requirements for the original chip are mainly in terms of storage capacity. Silicon Labs products with more than 32K RAM are now available. Support for the Thread protocol can be implemented. In addition to chip support, Silicon Labs offers Wi-Fi + Thread-enabled IP edge routers to demonstrate IPv6 connectivity while providing an air upgrade path from ZigBee to Thread.
Towel Ring is used to hang towels at home. Generally, its shape is ring or semicircle. It is used to place towels and wipe hands after washing hands. Depending on the designer, there will be some other shapes. The shape of the towel ring is also changeable and distinctive, which can meet the needs of different bathrooms.
The Bathroom Towel Ring is a household item for hanging towels. It is used to place towels to facilitate wiping after washing hands. Mainly used for hanging towels, the general shape is a ring or semicircle, but there are other shapes, the diameter is between 15cm~25cm, and the length is between 5cm~8cm. According to the designer and the shape, there are more styles to meet the needs of different bathrooms.
