Hainan Shidian Smart Park Solution

I. Project Background

Currently, the integration of applications based on the Internet of Things (IoT), cloud computing, artificial intelligence, edge computing, etc., combined with information application systems, building equipment management systems, public security systems, etc., integrates structure, systems, services, management, and their optimal combination to provide people with a safe, efficient, convenient, energy-saving, environmentally friendly, and healthy park environment. Benefiting from the application of IoT technology in smart parks, desired functions can be achieved more simply, providing an effective supplement to the intelligence of traditional parks, enabling the creation of modern new parks that can meet the development needs of an information-based society.

II. Drawbacks of Traditional Parks

Traditional park systems suffer from numerous issues:

1. High Energy Costs: Enterprises lack effective energy monitoring and management methods, leading to significant energy waste.
2. Low Security Protection: Fire prevention and disaster mitigation measures are scarce and outdated, lacking efficient and precise personnel management systems.
3. Poor Information Exchange: Lack of intelligent interaction between people, people and things, and things and things, and lack of effective status collection channels.
4. Insufficient Supervision and Maintenance: Personnel are dispersed, lacking interaction between people and the park, and lacking effective feedback channels.

III. Project Objectives

Overall, traditional parks generally lack effective technical means for centralized management. The "Smart Park" planned by West-HN Technology aims to solve the problems of traditional parks and achieve intelligent park management.

◍ The Smart Park primarily aims to achieve the following functions:

1. Reduce energy consumption and promote resource utilization efficiency
   • Through intelligent control of resources in areas such as parking lots, public spaces, and office areas, improve resource utilization efficiency, and reduce energy consumption and emissions.
2. Optimize work and living environments
   • Through intelligent means, monitor and regulate fire safety, security, air quality, etc., within buildings to create comfortable work and living environments.
3. Ensure safe and reliable operation
   • Through permission division, key area monitoring, and the linkage of fire prevention, disaster mitigation, and access control security systems, provide important safeguards for the safety of personnel, property, and data within the park.
4. Integrated Management Cloud Platform Linkage
   • Remotely display the monitoring status, cleanliness, and usage status of all equipment within the park range via a panoramic digital GIS platform. Conduct comprehensive and detailed analysis and statistics of public toilet basic information, achieving digital and intelligent management of traditional toilets and enhancing the city's image.

IV. Design Principles

Throughout the intelligent transformation design process, the following principles are consistently adhered to:

1. Maturity and Practicality Principle: The adopted equipment and technologies are mainstream, mature products with a significant user market in their respective application fields, prioritizing the satisfaction of users' business management needs as the primary factor.
2. Standardization and Modularization: Strictly follow relevant national and regional standards for system design and equipment configuration. Structure and standardize each subsystem according to the overall system architecture requirements, comprehensively reflecting advanced global technologies.
3. Ease of Management Principle: Utilize an advanced system management platform to achieve advanced distributed management. Make the management and control of the entire intelligent system more "precise" and "simple," highlighting "human-centric" design and improving the work efficiency of management personnel.
4. Economy Principle: Construct the intelligent system transformation with equipment offering a high performance-to-price ratio, maximizing the return on investment. Maintain system operation with lower costs and fewer personnel inputs, providing high efficiency and high benefits.

V. Smart Park Transformation Solution

Based on years of accumulated terminal product ecosystem and edge computing gateway technology, West-HN Technology's entire smart park solution employs technologies such as IoT, big data, cloud computing, and sensors. This enables traditional parks to possess capabilities for instant perception, accurate judgment, and precise execution, achieving refined management of the park and placing it in a leading position within the industry.
Terminals possess independent communication capabilities; failure of a single device does not affect the operation of the entire system. The variety of IoT devices is rich, and functional modules can be flexibly combined to avoid over-construction while meeting requirements. The platform is highly open and can interface with various third-party systems through standardized interfaces. Leveraging the massive access capabilities of the platform and gateways facilitates future expansion.
Based on communication methods such as Cat1, LoRa, and Zigbee short-range wireless, construction wiring can be effectively reduced, making it particularly suitable for the intelligent transformation of existing buildings.

◍ Solution Design Framework Diagram:

The overall solution hardware design centers on a multifunctional LORA gateway with computing capabilities. Most front-end detection sensors extensively adopt LORA wireless communication technology, while some indoor nodes use other methods such as Zigbee and BLE for transmission, sending collected data to the cloud platform.
