Currently, China has formed a spatial layout of smart parks characterized by “concentration in the eastern coastal areas, linkage along the central rivers, and distinctive development in the western regions.” The Bohai Rim, Yangtze River Delta, and Pearl River Delta regions have become the three major gathering areas for national smart park construction, relying on a large number of park platforms as a foundation; the central river region is vigorously developing smart park construction by leveraging the momentum of the urban agglomeration along the river; the western region is accelerating the layout of smart park construction projects by taking advantage of industrial transfer opportunities and combining their regional characteristics with the industrial development foundation of the parks. Moreover, parks in our country are transitioning from traditional industrial parks to new types, showing a trend of moving from lower to higher levels and from single to comprehensive parks.

The construction of smart parks can help achieve a comprehensive breakthrough in smart dynamics, industrial services, industrial development, and development planning, enabling the parks to achieve low-carbon operation, full-process control, in-depth development of information resources, and maximization of value through upgraded management models. Supported by informatization data, an efficient and high-conversion smart park information service management platform can be created to further promote the development of new strategic industries.
At the policy level, the government vigorously promotes the construction of smart cities. Since the 18th National Congress in 2012, the government report proposed the comprehensive construction of a moderately prosperous society, smart cities, and smart parks as an inevitable choice in the urbanization process of the country; in 2017, the State Council issued the development plan for the new generation of artificial intelligence, marking that the construction of smart cities has a top-level design and focuses on informatization construction.
The main demands of current smart parks are:
Smart park demands
Additionally, current smart parks mainly face the following pain points:
Pain points of smart parks
In addition to the aforementioned demands, smart parks also require some basic sensor devices such as smoke detectors, geomagnetic sensors, door magnets, water immersion sensors, and facial recognition. Currently, the mainstream networking solutions for these basic sensors include NB-IoT, LoRaWAN, and Zigbee. However, in the application scenarios of smart parks, some sensor nodes are located underground or in other enclosed spaces. NB-IoT, being based on the operator’s cellular network, may lack signals in some areas; while Zigbee is limited by its penetration ability and communication distance, also facing limitations in certain scenarios of smart parks. Therefore, overall, LoRaWAN is a very suitable networking communication solution for the construction of smart parks, as it encompasses some advantages of both NB-IoT and Zigbee in terms of network deployment flexibility and communication capabilities.
The architecture of ZLG Zhiyuan Electronics’ LoRaWAN solution is shown in the figure below:
Zhiyuan LoRaWAN solution architecture
ZLG Zhiyuan Electronics’ LoRaWAN node solution LM400TU is an industrial-grade LoRa networking transparent transmission module developed and designed by ZLG Zhiyuan Electronics. The module uses LoRa modulation technology derived from military communication systems, combined with spectrum spreading processing technology, to solve the problem of long-distance communication of small data volumes in complex environments. The LoRa networking transparent transmission module has an embedded self-organizing transparent transmission protocol, supports one-click self-organizing network for users, and provides LinkWAN protocol, CLAA protocol, and LoRaWAN protocol, allowing users to develop applications directly without spending a lot of time on protocols.
