Zigbee is a recently proposed two-way wireless communication technology with short distance, low complexity, low power consumption, low data rate, and low cost. It is mainly suitable for automatic control and remote control, and is different from GSM (global system for mobile communications ), GPRS (General Packet Radio Service) and other wide-area wireless communication technologies and IEEE802.11a, IEEE 802.11b and other wireless local area network technologies, the effective communication distance of zigbee is between several meters to tens of meters, which belongs to the category of personal area network. Thanks to the low communication rate and mature wireless chip technology, the complexity, power consumption and cost of zigbee devices are low, and it is suitable for being embedded in various electronic devices, serving wireless control and low-rate data transmission, etc. business.

The short-range wireless communication technologies that have developed rapidly in recent years include RFID (Radio Frequency IDentification) technology, zigbee technology, Bluetooth technology, and wifi module technology. These wireless communication technologies have their own characteristics. For the lighting system, zigbee and wifi technology are selected to form a wireless lighting network. In this system, users can not only control the lighting system, but also obtain lighting information through the feedback of the lighting system, that is, a system with two-way communication is designed, and zigbee is a wireless network technology for two-way communication. This is not available in Bluetooth technology and RFID (Radio Frequency IDentification) technology. At the same time, as a system, it must be stable, that is, it must be guaranteed to work more stably within a sufficient distance. From the perspective of communication distance, the communication distance of Bluetooth is only 10m, and the anti-interference stability of Bluetooth technology is poor. Although wifi technology has a long communication distance, its working power is very high, and it cannot maintain the wireless system for a longer period of time. RFID (Radio Frequency IDentification) technology is more used in the field of electronic tags, and does not have the function of two-way communication. The communication distance of zigbee is generally about 100m, which can fully meet the requirements of the system for communication distance. At the same time, it has the characteristics of low power consumption and can maintain the large operation of the system for a long time. In the structure of the wireless network, zigbee technology can realize automatic networking, that is, lighting equipment equipped with zigbee nodes can be automatically combined into a communication network, which can reduce the complexity of wireless network design. At the same time, the structure of each module of the zigbee system is relatively simple. The nodes, routers, and gateways of the zigbee sensor network can be implemented based on the hardware composed of a single-chip microcomputer equipped with a zigbee wireless transceiver, coupled with an internally running communication protocol. The communication in each node of the wireless network needs a communication protocol to organize the operation. Compared with other wireless communication standards, the zigbee protocol is compact and simple, and its specific implementation hardware requirements are very low, which can reduce the system design cost. At the same time, in terms of communication frequency, zigbee is a universal 2.4GHz band, so choosing zigbee can make the system applicable to any region.

Yeelink is a new open source Internet of Things platform. This platform connects the traditional single-chip microcomputer to the network card or wifi. The network layer implements the functions of the Internet of Things. Traditionally, gateways and routers are usually used to connect devices to the Internet. In this way, gateways, routers, and connected IP addresses are in one-to-one correspondence, that is, one IP address can only connect one device to the network. , so it cannot meet the requirement of connecting all lighting devices to the Internet in this system, and at the same time, the cost of this traditional method is also very high. As an Internet of Things platform, yeelink solves this problem very well. It connects each node to the network through positioning and virtual allocation of addresses, which not only meets the system design requirements, but also reduces costs. Therefore, using this open source Internet of Things platform, the microcontroller in the lighting system can be connected to the yeelink platform, and through functions such as positioning and monitoring, remote control of lighting equipment through the webpage can be realized.
