The main two functions of the multi-functional smart light pole are "multi-function" and "wisdom". The multi-function is mainly to load different functions such as urban road lighting, mobile network terminal, new energy charging pile, monitoring system, environmental monitoring system and emergency alarm system on a single light pole body; The wisdom is mainly reflected in the intelligent dimming system, the iot system based on 5G network, and the intelligent monitoring system.

The main purpose of this paper is to study the modularization of the internal equipment of the lamp pole and the standardization of the external shape of the lamp pole based on the two major functional characteristics of the multi-functional smart light pole, and to explore a scheme that can optimize and integrate the different functions of the multi-functional light pole in the limited space. And suitable for most areas of our country can efficiently and economically put into production of light pole appearance design standards. Improve the design and production construction efficiency of multi-functional smart light poles, and reduce the technical difficulty and cost of later operation and maintenance.

First, the development trend of multi-functional smart light poles

Since the 19th National Congress, multi-functional smart light pole has entered a period of high-speed and comprehensive development, the construction of new smart cities around the country has accelerated, and the construction of multi-functional smart light pole has entered a blowout stage of development. At the same time, with the improvement of people's living standards, the function of the light pole has brought new functional requirements, and the realization of 5G technology commercial operation and the development and maturity of the Internet of Things technology have made the function of the multi-functional smart light pole more complex and diverse. How to run orderly and efficiently in a limited space and how to achieve large-scale industrial production of multifunctional light poles has become an urgent problem to be solved.

China's new multi-functional smart rod concept pays more attention to the following characteristics: modularity, standardization, and synergy.

(1) Modularity. The most important problem to be solved is how to optimize and coordinate between different functions within a limited space range, so that the same module components of different functions are integrated using modular design to streamline equipment and improve hardware utilization efficiency.

(2) Standardization. The multi-functional smart pole should strive to promote the standardization of the light pole from the internal structure to the external profile and the various functional devices, and break the technical barriers between the light pole and the functional module and between the functional module and the functional module.

(3) Synergy. The new multi-functional smart rod is not a simple collection of functions, but a miniature co-processor that brings together different resources and integrates them, giving play to the advantages of 1+1 > 2 between each sub-function. To realize the interconnection and horizontal linkage of information between government departments and business lines in the city.

Second, multi-functional smart light pole function composition

The function of multi-functional light pole is not fixed, on the one hand, with the development of The Times, its function will have corresponding increase and decrease and upgrade, on the other hand, affected by the actual needs of application scenarios, there will be corresponding function increase and decrease [5]. According to the current technical conditions and actual market demand, the main functions of the multi-functional light pole include: smart lighting, information release, video surveillance, public emergency, environmental monitoring and network services.

Third, the modular design of multi-functional smart light pole

The function of the multi-functional smart light pole covers a number of areas, and different functions require different functional modules and hardware equipment to provide support, which results in the interleaving of the various system modules inside the multi-functional smart light pole, the internal space required is large, and the line structure is more complex. Not only is it easy to fail in the operation of the light pole, which brings inconvenience to the maintenance and overhaul of the later period, but also directly affects the appearance of the light pole, resulting in the "bloated" external shape of the light pole, affecting the overall coordination of the light pole and the environment.

In order to solve the problem that the number of hardware modules caused by the complex functions of the multi-functional smart light pole is too large, after careful and in-depth research on the functions and attributes of different functional modules, different functional modules are classified, and the modules with the same or similar functions are summarized. Then through technical means to optimize the integrated design into a free combination of "plug-and-plug module".

Fourth, multi-functional smart light pole design standardization

Multi-functional smart light poles from the beginning of their birth to now have also been moving towards the goal of standardization. The standardization of multi-functional smart light poles is an important sign of its mature development, and it is also an essential factor in regulating the healthy development of the industry and seeking to maximize social benefits. The standardization of multi-functional smart light pole design includes: (1) The standardization of multi-functional smart light poles with equipment at different heights; The number of different functions of the multi-functional smart light pole corresponds to the standardization of the level of the light pole.

Multi-functional smart light pole equipment loading at different heights

1. Standardization of multi-functional smart light pole bar profile

The standardization of the multi-functional smart light pole body profile is an important guarantee for industrial large-scale production, and the standardized profile design can greatly shorten the lamp pole design and production cycle, and can also greatly reduce the overall cost of the lamp pole, creating favorable conditions for the social promotion of the multi-functional smart light pole. For example, according to the time and scene differentiation of the different functions of the multi-functional smart light pole, a sliding rail light pole profile with removable, removable and adjustable external functional equipment can be designed, so as to facilitate the increase or decrease, update and adjustment of the later equipment.

2. Standardization of multi-functional intelligent light pole insertion module

Plug and plug modules are like electrical sockets, and different functional devices are like various types of electrical equipment, and the equipment is connected to the socket through the plug, so as to obtain the energy supply and control signals to provide the normal operation of the equipment. The standardized design of the plug module is just like the internationally recognized USB plug hole, and any device with the plug plug of the plug module can be connected to the plug module as easily and efficiently as the USB plug is connected to the USB jack, thus facilitating the expansion of the multi-functional smart light pole equipment and the later operation and maintenance of the project.

V. Conclusion

Under the wave of 5G network, big data era and Internet of Things era, the construction of multi-functional smart light pole has been pushed to the forefront and has become an important component of the construction of the new base. The diversity and complexity of functional facilities make the modular and standardized development of multi-functional smart light poles imperative, and under the guidance of modularity and standardization, it will accelerate the speed of promoting the development of multi-functional smart light poles, the expansion of production scale and the landing of actual projects. To provide more economic, high-quality and convenient services for the construction of smart cities, economic and social development and the improvement of people's living standards.
