Introduction

In the wave of Industry 4.0 and digital transformation, how to quickly realize device interconnection, data collection and automatic control has become the core demand of various industries. The powerful combination of ARMxy series industrial-grade ARM computers and Node-RED visual programming tools provides a set of flexible, efficient and low-code solutions for industrial Internet of Things, agriculture, energy storage, smart cities and other fields. This article will start from the actual application scenarios and analyze how this combination enables the intelligent upgrade of multiple industries.

1. Industrial IoT : Multi-protocol interconnection and cloud integration

Pain points: Factory equipment is multi-source and heterogeneous, PLC, sensors, etc. use different communication protocols, and data island problems are prominent.

Solution:

ARMxy connects field equipment through RS485, CAN, Ethernet and other interfaces, supports mainstream industrial protocols such as Modbus RTU/TCP, OPC, MQTT, and realizes real-time data collection.

Node-RED has a built-in 5000+ protocol library, which can quickly complete protocol conversion and upload data to cloud platforms such as Alibaba Cloud and AWS IoT through visual process orchestration.

Benefits: Break data islands, realize equipment interconnection, cloud storage and analysis, and provide data support for predictive maintenance and production optimization.

2. Protocol conversion: seamless collaboration across brands of equipment

Pain points: Incompatible protocols of equipment from different manufacturers in industrial environments, low collaboration efficiency.

Solution:

Node-RED automatically converts data formats through protocol libraries (such as Siemens PLC and Mitsubishi CNC protocols), and ARMxy provides hardware interface support to achieve data interoperability between PLCs and instruments.

Benefits: Reduce integration complexity, improve equipment collaboration efficiency, and reduce development cycles and costs.

3. Agricultural planting: environmental perception and automated management

Pain point: Traditional planting relies on manual monitoring, and environmental regulation lags behind.

Solution:

ARMxy connects temperature, humidity, light, and soil sensors to collect environmental data in real time.

Node-RED automatically triggers irrigation, ventilation, and lighting equipment according to preset rules (such as soil moisture thresholds), and remote monitoring is achieved through 4G/Wi-Fi.

Benefits: Accurately control the crop growth environment to improve yield and resource utilization.

4. Smart Farming: Environmental Control and Precision Feeding

Pain Points: The farm environment fluctuates greatly and manual management is inefficient.

Solution:

ARMxy connects to CO₂ sensors and temperature control equipment to monitor the farming environment in real time.

Node-RED controls the fan and heater through the DI/DO interface, and links the feeding system to automatically feed according to time or environmental conditions.

Benefits: Ensure the stability of the farming environment, reduce the risk of epidemics, and improve production efficiency.

5. Energy storage system: full life cycle monitoring and safety control

Pain points: Insufficient monitoring of battery pack status (such as SOC, SOH) poses safety risks.

Solution:

ARMxy collects battery voltage, temperature and other data through the CAN bus, and Node-RED analyzes and sets threshold alarms in real time (such as high temperature triggering the cooling system).

After uploading the data to the cloud, the charging and discharging strategy can be adjusted remotely or an emergency shutdown can be initiated.

Benefits: Extend battery life and improve the safety and operation efficiency of the energy storage system.

6. Smart City: Intelligent Operation and Maintenance of Infrastructure

Pain Points: Urban facilities (such as street lights and charging piles) are widely distributed and have high maintenance costs.

Solution:

ARMxy connects smart street lights and charging piles to collect equipment status and energy consumption data.

Node-RED automatically adjusts street light brightness or signal light duration according to time, traffic flow and other parameters, and realizes automatic fault alarm.

Benefits: Optimize resource scheduling, reduce energy consumption, and improve urban management response speed.

Summary: Flexible and efficient, empowering industry upgrades

The combination of ARMxy and Node-RED has become an industry intelligence tool with three core advantages:

1. Multi-interface compatibility: supports rich interfaces such as RS485, CAN, 4G, etc., and adapts to complex industrial environments.
2. Low-code development: Node-RED visual programming greatly reduces the development threshold and shortens the project cycle.
3. Cloud collaboration: seamlessly connect to mainstream cloud platforms to achieve data aggregation and remote control.

Whether it is industrial protocol conversion, agricultural precision regulation, or energy storage safety management and urban smart operation and maintenance, this combination can promote the transformation of traditional industries to intelligence and automation in an efficient and low-cost way. In the future, as more industry scenarios are explored, ARMxy and Node-RED will continue to release their potential and become the core engine of digital transformation.
