Description

technical field

[0001] The invention relates to an intelligent integrated power supply device of the Internet of Things, belonging to the field of electronic technology. Background technique

[0002] Where there are street lights on the street, there are light poles and public lighting power sources. In the traditional concept, the role of light poles and lamps is only public lighting at night. Since the concepts of smart city big data systems and Internet of Things systems have been gradually put into practice, and have made great progress With the rapid development of the city, people have gradually realized that the urban public lighting system composed of light poles, lamps and their power supply network is the most potential infrastructure for the intelligent development of cities in the future, and has unparalleled resource advantages. In addition to ensuring the basic functions of public lighting, light poles and lighting power supply networks can also easily derive m...
