Application Layer: IoT Connectivity and User Interaction

The application layer serves as the bridge between IoT technology and end users. It is tailored to meet the specific needs of the industry and promote intelligent IoT applications. In this layer, Naan's V-BOX Cloud platform serves as the fundamental foundation for IoT application management.
Unlike conventional cloud platforms, V-BOX has the capability to control interfaces, trend graphs, reports, alerts, and mobile apps. Notably, it can be easily configured by individuals with limited programming knowledge but strong computer skills. V-BOX collects data from various sensors, such as temperature, water level, and pressure parameters, and subsequently stores and manages this data for dynamic displays and automatic machine control.
Furthermore, this layer ensures automatic alerts for abnormal conditions, such as low water level or high water level alarms, and enables real-time monitoring of boilers from various angles through camera installations.

Network Layer: Smooth Data Transmission

The network layer encompasses various networks, including the Internet, television and radio networks, network management systems, and cloud computing platforms. It is responsible for transmitting and processing data acquired by the sensor layer. V-BOX is specifically designed for cloud configuration, ensuring smooth data transmission to cloud servers or local storage.
It features remote querying and incremental data transmission to guarantee data integrity. Additionally, V-BOX supports advanced functions such as remote program uploads and downloads for PLC programs and online program debugging, significantly reducing post-sales costs and travel expenses.

Sensor Layer: Optimal Data Collection

The sensor layer comprises various types of sensors, including temperature and humidity sensors, water level sensors, wind differential pressure sensors, steam pressure sensors, and more. These sensors collect vital equipment information, which is then processed by PLCs to gather data.

Platform Deployment: V-NET

V-BOX can be connected to H-4G's V-NET for swift network setup for various mechanical equipment and systems controlled by PLCs, enabling unattended operation. Users can easily establish an industrial Internet platform using the "what you see is what you get" (WYSIWYG) development approach.

System Construction Goal

The V-BOX IIOT solution aims to utilize the automatic control system of boiler manufacturers to perform the conversion of various communication interfaces and protocols without affecting the normal boiler operation. It focuses on distributing on-site boiler parameters (such as furnace parameters, auxiliary machine parameters, operating parameters, etc.) and generating operational data (automatic data collection, remote real-time monitoring, intelligent alerts, etc.) for remote monitoring and data querying of boilers from anywhere via computers or mobile phones. V-BOX IIOT provides robust support for equipment operation and maintenance, after-sales service, equipment upgrades, fault alerts, and issue resolution.

Applications of the Smart Boiler System

This system optimally integrates boiler plants and pipe networks, enabling real-time monitoring and management of boiler operation status, sensor-detected temperature, steam pressure, and more. This integration enhances management and control and establishes a real-time data center for remote diagnostics by technical teams.
Through equipment and sensor data collection, it supports optimal boiler facility management and scheduling options, provides equipment status monitoring, integrates production with real-time equipment assets, establishes comprehensive status monitoring of critical equipment, and correlates equipment status with real-time production conditions. This fully reflects equipment static and real-time information, providing a basis for equipment maintenance.

The control plan primarily utilizes the NAAN PLC LX3V-1412mt, HMI PI307i, and V-BOX H-4G, featuring user-friendly and visually appealing interfaces. The mobile app extends the system's capabilities, allowing remote monitoring, control, diagnostics, vendor support, and even online code modifications.

Advantages of the Smart Boiler Program

  • The system is designed with modularity and hierarchy to enhance efficiency, maintainability, and scalability.
  • Users can upgrade and replace controlled hardware equipment without changing the software base, offering flexibility and cost savings.
  • Advanced data collection capabilities support statistical analysis for efficient boiler management.
  • Strong electromagnetic interference resistance ensures reliable operation in challenging environments with high electromagnetic interference.
  • Automatic fault detection enhances system robustness and adds aesthetic appeal to the equipment department.


The emergence of IIOT has spurred rapid integration between large equipment management and information, effectively addressing many challenges and risks facing the industry today. We believe that with the continuous improvement of boiler informatization, smart boiler technology will usher in a new era of rapid development.
