Wireless communication protocol establishing method and wireless communication system suitable for intelligent illumination

Abstract

The invention provides a wireless communication protocol establishing method suitable for intelligent illumination. The method comprises that an MAC physical layer, an address and routing layer and an application layer are established; wireless signals are transmitted and received in the MAC physical layer by utilizing a 2.4G common wireless frequency band; standard TCP and UDP transmission protocols are realized in the address and routing layer; an application transmission protocol is built in the application layer; and in the address and routing layer, an address distribution rule is realized by converting a 6-byte hardware MAC address consistent with the IPv6 into IPv6, concretely, FF-FE is inserted between the third and fourth bytes of the MAC address, a 64-bit address is formed, the second lowest bit of the first byte is reversed, and an IPv6 address prefix is supplemented in front of the MAC address. The wireless communication protocols of the invention meet the requirements of high reliability, low time delay and high consistency, is highly expansible, and can be operated in a resource-constrained single-chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for establishing a wireless communication protocol suitable for intelligent lighting and a wireless communication system. Background technique [0002] At present, common wireless protocols based on public frequency bands include WIFI, Bluetooth, Zigbee, etc. These wireless protocols are also used in intelligent lighting systems and products. However, due to their inherent characteristics, these general protocols have some unavoidable defects when they are applied to intelligent lighting. For example, WIFI is used for high-speed data Internet access of computers and smart devices. The number of nodes that can be connected to a single center is limited, and it cannot actively switch when the signal is weak. At the same time, the wireless power consumption is high; the Bluetooth protocol is used for short-range audio and other entertainment. , Auxiliary equ...

However, due to their inherent characteristics, these general protocols have some unavoidable defects when they are applied to intelligent lighting.

For example, WIFI is used for high-speed data Internet access of computers and smart devices. The number of nodes that can be connected to a single center is limited, and it cannot actively switch when the signal is weak. At the same time, the wireless power consumption is high; the Bluetooth protocol is used for short-range audio and other entertainment. , Auxiliary equipment communication, can only support communication between single points, and the effective communication distance is very short; Zigbee protocol is used for large-scale, low-speed, low-reliability communication in industry and agriculture, etc. Networking and data mutual transmission to keep the network smooth, the communication delay is very large, the performance is unstable, and the packet loss rate is high

When these protocols are applied to smart lighting products, it is generally difficult to adapt to the common needs of large-scale smart lighting, the user experience is poor, the synchronization between lamps is difficult to guarantee, and often the lamps and nodes are out of control
