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...

Problems solved by technology

[0003] However, there are a large number of detectors, sensors and data transmission devices in the above-mentioned various and different independent systems, so it is inevitable to install an adaptive power supply used with these devices to solve the power supply problem, which is not only The total number of components is greatly increased, occupying limited space, and the messy discrete power supply and lead wire poles on each light pole bring difficulties in construction and maintenance, and are prone to failure or even accidents, which is extremely unfavorable to safe operation

[0004] In addition, there is another practical problem, that is, in a wide variety of different systems, the requirements for the number, distribution density, and even geographical location and environmental conditions of various front-end devices in their own systems are all different. There are differences, which leads to the fact that the types and quantities of IoT devices arranged on each light pole may be inconsistent. If the traditional fixed voltage output type DC regulated power supply is still used for centralized power supply, it will be difficult to achieve power supply models and specifications. Uniform and inconvenient for design, procurement and engineering application
