4G Industrial Router with Protocol Conversion

In today’s era of deep integration between Industry 4.0 and the Internet of Things (IoT), seamless device-to-device connectivity has become a cornerstone of enterprise digital transformation. However, industrial sites are often filled with equipment from various manufacturers using different communication protocols. The real-world challenge lies in making these devices “speak” a common language to enable seamless data flow. The Multi-Protocol Conversion 4G Industrial Router is designed precisely to address this need. With its powerful protocol conversion capabilities, robust industrial design, and flexible remote communication features, it serves as an ideal choice for building intelligent industrial networks.

Core Functionality: Bridging Protocol Barriers for Unrestricted Data Flow

Engineered for complex industrial environments, the core value of this industrial router lies in its exceptional multi-protocol conversion capability. Acting as an interpreter between different devices, it bridges data pathways through two key functions: downlink acquisition and uplink forwarding.

Downlink Acquisition: Connecting Diverse Field Devices
The device supports data acquisition using multiple mainstream industrial protocols, enabling seamless connectivity with controllers, sensors, and smart instruments from different brands. Supported protocols include:

• Modbus RTU: Acquired via RS-232/RS-485 serial ports, ideal for a vast number of traditional field devices.

• Modbus TCP: Acquired via Ethernet port, suitable for connecting modern equipment that supports Ethernet-based communication.

• IEC 104: Acquired via Ethernet port, widely used in the electric power automation sector.

• DL/T 645: Acquired via RS-485 interface, complying with the Chinese electric power industry standard for reading data from metering devices like electricity meters.

Uplink Forwarding: Seamless Integration with Upper Management Systems
After internal processing, the acquired data can be forwarded to cloud platforms or monitoring centers using various protocols:

• Modbus TCP: Outputs data in the standard Modbus TCP format for easy integration with mainstream SCADA software and platforms.

• IEC 101 / IEC 104: Supports forwarding protocols compliant with electric power industry standards, suitable for integration into power dispatching systems.

• MQTT: A lightweight IoT communication protocol, particularly effective for pushing data to cloud platforms to enable remote monitoring and big data analytics.

Through this flexible architecture that separates acquisition from forwarding, the device effectively resolves the issue of protocol incompatibility on industrial sites, connecting scattered “data silos” into a unified “data network.”

Industrial-Grade Design: Built for Harsh Environments

Industrial sites are often characterized by complex and variable conditions, demanding high standards of stability, reliability, and environmental resilience. This router is designed from the ground up with industrial-grade standards, covering both hardware and software.

• High-Performance Hardware Platform: Powered by a 32-bit MIPS dual-core industrial-grade processor and equipped with 128MB of system memory, it delivers robust data processing capabilities, ensuring stable operation even under multitasking conditions.

• Wide Temperature and Voltage Tolerance: Supports an extreme operating temperature range of -35°C to 75°C, suitable for both high-heat and freezing environments. It features a wide voltage input range of 9~36VDC to handle unstable power supplies on-site and includes built-in reverse polarity protection.

• Comprehensive Interface Protection: All critical interfaces are equipped with robust protection circuits. Ethernet ports feature 1.5KV electromagnetic isolation protection, the SIM card slot has 1.5KV ESD (Electrostatic Discharge) protection, and antenna ports can optionally include surge protection. These features effectively mitigate risks of damage from electrical interference, static electricity, or lightning strikes.

• Dual Watchdog Mechanism: Incorporates both hardware and software watchdog timers. In the event of system or network anomalies, the device can automatically reboot to recover, ensuring continuous, 24/7 operation and virtually eliminating system freezes.

Flexible Communication: Wired + 4G Dual-Link Backup

As an industrial-grade router, it offers a variety of network connectivity options to ensure reliable data communication.

• Dual Ethernet Ports: Provides one WAN/LAN combo port and one dedicated LAN port, both 10/100Mbps. It supports PPPoE dial-up, static IP, dynamic IP, and other access methods, adapting flexibly to different network environments.

• 4G Cellular Network: Integrates an industrial-grade 4G communication module supporting mainstream FDD-LTE, TDD-LTE, and WCDMA frequency bands. Simply insert a SIM card to establish a wireless network connection quickly. This is crucial for remote areas without wired network coverage or as a backup link for wired connections.

• Intelligent Link Backup: Supports intelligent dual-link hot backup between wired and 4G mobile networks. If the primary link fails, the device automatically switches to the backup link, ensuring uninterrupted data transmission and providing communication redundancy for critical operations.

• High-Speed Wi-Fi: Supports the 2.4GHz 802.11n wireless protocol with a theoretical maximum rate of 300Mbps. It can act as a wireless Access Point (AP) for other Wi-Fi devices on-site or function as a wireless Client to connect to external Wi-Fi networks.

Convenient Management and Maintenance

Considering the typical scale and distribution of industrial projects, this router emphasizes ease of use and maintainability.

• Rich Management Options: Supports local web-based configuration, remote web access, and optional centralized cloud platform management. Administrators can perform remote configuration, status monitoring, and log viewing without needing to be physically on site.

• Comprehensive Remote Maintenance: Supports SYSLOG for remote logging to trace device operational history. It also supports local or remote online firmware upgrades and configuration file import/export, significantly improving operation and maintenance efficiency.

• Intuitive Status Indication: Features up to 10 status LEDs on the front panel, indicating system status, network connectivity, signal strength, VPN status, SIM card status, etc. This provides a quick, at-a-glance understanding of the device’s operational state, facilitating rapid troubleshooting on-site.

Typical Application Scenarios

Leveraging its combined strengths in protocol conversion, stability, and flexible networking, this industrial router is widely applicable across numerous industries:

• Smart Manufacturing: Connects PLCs, robotic arms, sensors, and other equipment on production lines. It acquires and converts data from different protocols, uploading it to MES or cloud analytics platforms to enable production transparency, predictive equipment maintenance, and real-time anomaly alerts.

• Power & Energy: In applications such as substations, distributed photovoltaic systems, and EV charging stations, it acquires data using power industry protocols like IEC 104 and DL/T 645. This data is uploaded to dispatch centers or energy management platforms via 4G or Ethernet, enhancing grid operational efficiency.

• Smart Water & Environmental Protection: Deployed at remote sites like pumping stations, wastewater treatment plants, and environmental monitoring stations, it connects instruments such as flow meters, water quality analyzers, and level sensors. Collected Modbus data is uploaded to cloud platforms via MQTT for remote monitoring and unattended operation.
