With the rapid development of Internet technology, sensing technology and information processing technology, the Internet of Things has received more and more attention. The US "Technical Review" magazine ranked the Internet of Things as the top ten technology to change the future. In the Internet of Things, there are several parts, such as sensing, transmission, cloud computing, and control. The most important one is the transmission part, wireless communication technology. In the current Internet of Things applications, wireless transmission technology can be described as many, the most commonly known to the public is Wifi, Bluetooth and NFC, but unusually, the relatively unfamiliar zigbee technology has been adopted by many companies that do smart home and intelligent lighting control, Including smart home kits from Xiaomi, products from traditional big companies such as Huawei and ZTE, and being labeled as “smartâ€, it is one of the most likely communication technologies to change our lives. Light up the smart city In fact, zigbee technology has been developed in China for more than 10 years. At first, only a few companies were doing zigbee technology, mainly used in the industrial field, including a Shanghai company, Shunzhou Intelligence, which independently developed the first The zigbee wireless transmission module for industrial serial wireless communication has survived the development of the Internet of Things and has become one of the representative companies in the zigbee technology field. Zigbee technology is really concerned by the whole society. After the Internet of Things was officially listed as the five emerging strategic industries by the state, a large number of emerging Internet of Things companies emerged, and zigbee technology gradually entered the fields of smart home, intelligent lighting control, building control, and intelligent security. Start to enter the public eye. At present, the application of zigbee technology is relatively mature, and there is an intelligent management of urban lighting in the field of “big-bangâ€. ZigBee has the ability to communicate in both directions, not only to pass commands to the device, but also to feed back the device execution status and related data. Based on this, Shunzhou Intelligent developed the zigbee single-lamp intelligent lighting control system, using a unified cloud platform for efficient management, enabling remote switching of single lamps, dimming, and monitoring without changing the structure of the lamps or adding wiring. And loop control to achieve energy saving, environmental protection, intelligent control. Moreover, zigbee can also access sensors for wireless data acquisition and monitoring. Through the intelligent control system, remote centralized management and real-time monitoring of street lamps can be performed, and real-time remote collection of temperature, power, current, voltage and other related data when all street lamps work. The system combines the information data of the intelligent Internet of Things street lights, and the management page can clearly grasp the location and abnormal causes of the abnormal street lights, and realize the intelligent and refined management of the lighting system. The key to this application is zigbee's ad hoc network capability, which uses a mesh network structure, with a master node managing several child nodes and a maximum of 65,000 nodes. In the current urban road lighting management, it is possible to use a centralized manager to wirelessly control more than 1000 large-scale street lights. Zigbee is the most suitable solution, which will strongly promote the management and construction of “smart cityâ€. Entering smart life Speaking of smart home is no stranger to everyone, but what time is it to push smart home more than 20 years ago? Bill Gates laid a 84-kilometer cable to realize all his appliances in order to realize his smart mansion. The devices are connected into a home network and cost $530 million. Nowadays, only the communication module needs to be embedded in the various devices of the home, so that the interconnection between products can be realized, so that it can be passive (no external power supply), wireless management, and can enjoy the automation and intelligent control, and the investment of the mature wireless solution. Make smart homes truly enter the homes of ordinary people. There are many wireless transmission technologies, but it is not easy to achieve passive and wireless management, low transmission power consumption and long-lasting equipment. From a technical point of view, WiFi is currently the most expensive in the transmission technology that is well known today. Zigbee uses a very low-power design that can be fully battery-powered. Two 5th dry cells can support 1 node for 6-24 months or even longer. Most importantly, zigbee's self-organizing technology makes intelligence simpler and more convenient, and no matter how many smart home products are added to the home, zigbee technology can easily handle it. According to the information released by Shunzhou Intelligent official website, its newly developed zigbee module is powered by two dry batteries, and the standby time can be up to 10 years. Its ultra-low power module can fully satisfy the low-power of the Internet of Things. Application requirements. It is not difficult to see that zigbee is becoming the first choice for smart homes with its stability, low power consumption and low cost. Various smart products are being integrated into the living, clothing, food and shelter of people's lives. Deeply affect people's lives... Open a new field of aerospace In addition to the home and lighting control areas mentioned, the scope of application of zigbee technology is expanding in an unstoppable manner. According to the official news of Shunzhou Intelligence, Shunzhou's zigbee products have been successfully applied to satellite ground detection, providing a new satellite ground test method for the aerospace science and technology field. This is not only an endorsement of zigbee technology, but also a major breakthrough in the new field of zigbee technology. Satellite ground test technology is an important branch of space technology. In order to ensure the reliability of satellites, a large number of satellites must be tested. In the test process, real-time communication, real-time control, real-time data processing and other complex tasks are required. The test equipment that joins the ZigBee protocol can achieve twice the result with half the effort. The most important thing is to ensure the security of the test data. The security and anti-jamming capability of zigbee technology is its most obvious feature. Its systematic design has not yet cracked a precedent in the world, and wireless technologies such as WiFi and Bluetooth have frequent security incidents. This shows its security position in the field of short-range wireless communication. Zigbee provides a three-level security model, including no security settings, access control lists (ACLs) to prevent illegal access to data, and symmetric passwords using the Advanced Encryption Standard (AES 128) to flexibly determine its security attributes. The security of the zigbee network. From this point of view, zigbee wireless technology and other areas continue to merge, eventually leading the market and to a wider range of applications. With the advancement of technology and the decline of cost, the connection between people, things and things, people and things will be smarter and more extensive, and the wireless technology revolution will enter a new development milestone.
