Recently, the ZigBee Alliance announced that the new ZigBee Internet Protocol (IP) 920IP has been developed and tested. The standard is the world's first Internet Protocol 6th Edition (IPv6) based wireless mesh network (MeshNetworking) solution, which will be applied in the future. Enhance the energy efficiency and interoperability of IoT devices in low-power and low-cost home energy management grid networks and related devices. With the rise of mobile internet and smart wearable devices, there is an urgent need in the industry for connectivity and compatibility of low-energy sensors and chips. The ZigBee Alliance launched a new protocol, 920IP, in response to the Japanese Ministry of Internal Affairs and Communications (MIC) designating 920MHz for the Home Energy Management System (HEMS) and pushing the lean version of ECHONET to become the standard for smart homes. The ZigBee Alliance has reached an agreement with the Japan Telecommunications Technical Committee (TTC) and the ECHONET Alliance to advance the 920 IP protocol. ZigBee launches new protocol 920IP It is reported that the 920IP protocol will support the simplified ECHONET and HEMS. This standard enhances the IEEE 802.15.4 standard by adding network layers, security layers, and application frameworks. In addition, the 920IP protocol is based on standard Internet protocols, providing cost-effective and energy-efficient wireless multi-hop (MulTI-hop) mesh networks such as 6LoWPAN, IPv6, UDP and Routing Protocol (RPL). In addition, the 920IP protocol also supports Advanced Encryption Standard (AES)-128- such as Transport Layer Security-Pre-Shared Key (TLS-PSK), Extended Authentication Protocol (EAP), PANA, Link Layer Frame Security, etc. CCM algorithm for security and identity verification. The head of the ECHONET Association pointed out that the streamlined ECHONET will become the application interface standard for HEMS in Japan; therefore, the ZigBee Alliance has a simplified ECHONET and 920MHz option, and can expect higher interoperability and popularity in the market in the future. The Japan Telecommunications Technical Committee expects that the 920IP promulgated by the ZigBee Alliance will become a global standard and, after its release, will drive energy management solutions everywhere and expand penetration in the Japanese market. It is reported that the future update of the 920IP standard will be handled by OKI, NECEngineering, Ad-SolNissin, Texas Instruments and Skyley Networks. Internet of Things will change the future of life The Internet of Things, as its name implies, is the Internet connected by objects. It uses the Internet as its core and foundation, and it is a network system that extends and expands on the basis of it. And its client can be extended and extended to any item and item for information exchange and communication. Therefore, the Internet of Things can be defined as a radio frequency identification (RFID), a sensor, a two-dimensional code, etc., which are connected to a wireless network through an interface, thereby providing an object with "intelligence" and enabling communication between a person and an object. And dialogue, you can also achieve the communication and dialogue between objects and objects. This network that connects objects is called the "Internet of Things." IPv6, which is currently being popularized, can be considered to support an unlimited number of connections. Therefore, through the sensor network, items can be collected, transmitted, analyzed and distributed in large quantities through low-energy sensors, making family life more comfortable. Sensors based on the Zigbee, 6LoWPAN and Z-wave standards are now being used in large numbers. For example, Zigbee has been built into smart appliances and smart meters. 6LoWPAN (based on IPv6) has been used by the Internet's father, VintCerf, in its own cellar temperature monitoring system. Z-Wave is the foundation of Verizon's intelligent home automation service. And there are still many innovative ways of using them. Sparked, a Dutch startup, implanted sensors on the ears of cows to monitor the health and whereabouts of cows. Sensors are also embedded in shoes, asthma sprays, and other research and surgical equipment. Internet of Things will connect the world intelligently In summary, with the debut of the new ZigBee protocol and other IoT protocols and applications in the gradual improvement, we have seen a broad space for the development of the Internet of Things, and also outlined a blueprint for intelligently connecting the world. We look forward to more and better IoT technologies and related products, which will be rapidly popularized in the near future, and will be convenient for people in terms of food, clothing, housing and transportation. The civil air defense alarm control system is a wireless dual control system developed specifically for civil air defense alarms. This system utilizes wired or civil air defense wireless dedicated frequency points, equipped with alarm controllers (control units, radio stations, wireless modems, wired interfaces), computers, etc., to automatically release and manage various alarms in the civil air defense alarm system The system equipment is easy to operate, with functions such as state echo and network management, as well as anti-interference and encryption (anti hostile sabotage) functions. Communication is reliable and efficient. Control device, control unit, Alert system, Safety warning system, Warning device Taixing Minsheng Electronic Co.,Ltd. , https://www.ms-speakers.com
