At present, lighting mainly relies on manual control of field switches. The use of Internet of Things technology to realize wireless remote control of lighting systems is a new development trend. In this paper, the wireless self-organizing network technology is used to control the central node of the self-organizing network module through the serial output of the Openwrt router and the web page, and then the lighting of the self-organizing network module is wirelessly controlled, thereby realizing the wireless remote control of the lighting system. The internal network penetration technology is used to extend the LAN of the router to the wide area Internet, and the remote control of the lighting system is further realized. The lamp control mode does not need to be operated at a fixed switch point, and the remote control of the light can be performed anytime and anywhere by using a networked computer or a mobile terminal, which is very fast and convenient. The system has practical application value in centralized control and remote control of lighting systems in factories, schools, buildings and large public places.
