Product Description

W4G 4G Ethernet Dual-Network Industrial Control Board for Smart Parking & Access Control

Product Introduction

 

The W4G industrial control board is a high-performance embedded controller designed for smart parking lot management and industrial access control systems. As the core of the electrical control system, it integrates 4G cellular communication, Ethernet connectivity, and rich industrial interfaces to solve the pain points of traditional control systems-such as network instability, difficult remote maintenance, and poor compatibility with peripheral devices.

 

Equipped with an ARM Cortex-M3 32-bit high-speed processor and a real-time embedded operating system, the W4G supports automatic dual-network switching (Ethernet ↔ 4G) and offline data operation, ensuring 24/7 uninterrupted work in unattended scenarios like parking lots, industrial parks, and commercial complexes. It fully complies with industrial-grade standards, with a wide operating temperature range and multiple protection functions, making it the first choice for system integrators and engineering projects.

 

 

Core Features of W4G Control System

 

1.   Dual-Network Auto Switch Technology
   Automatically prioritize Ethernet for stable data transmission; seamlessly switch to 4G when the wired network fails, and switch back after recovery. This ensures zero downtime for the control system and reduces 4G traffic consumption.
    
2.   Comprehensive Industrial Interfaces
   The board is equipped with 2×RS232, 2×RS485, 2×Wiegand (26/34 adaptive), 6×IO input channels, and 2×relay isolated output channels. It is fully compatible with license plate recognition (LPR) cameras, barrier gate, LED screens, voice broadcast devices, and other peripheral equipment.
    
3.   Offline Operation & Data Security
   Built-in large-capacity storage supports up to 16,000 offline whitelist entries and offline transaction record storage. All data will be automatically uploaded to the cloud platform once the network is restored, avoiding data loss.
    
4.   Standard MQTT Cloud Docking
   Supports the standard MQTT protocol (QoS 1) for seamless integration with customer cloud management platforms. Realize remote control of barrier gate, real-time status monitoring, firmware upgrades, and log collection-all operations can be completed remotely without on-site maintenance.
    
5.   Industrial-Grade Reliability
   With reverse connection protection, ESD/pulse protection, and overcurrent protection, the W4G can operate stably in harsh environments with temperatures ranging from -40ºC to 85ºC and relative humidity of 10%~90% (no condensation).

Application Scenarios of W4G Electrical Control System

 

1. Smart Parking Lot Management

 

• Connect LPR cameras to receive vehicle recognition data in real time.
• Control barrier gate to open/close automatically via relay output.
• Display parking fees and QR codes on LED screens (via serial communication).
• Realize offline payment and whitelist vehicle access without network.

 

2. Industrial Access Control System

 

• Link with card readers (Wiegand interface) for employee access management.
• Remote access control via cloud platform (open/close doors anytime, anywhere).
• IO input detects door status (open/closed) and triggers alarm if abnormal.

 

3. Unattended Industrial Equipment

 

• Remote control and monitoring of industrial machinery via 4G/Ethernet.
• Offline operation ensures production continuity when the network is down.
• Remote firmware upgrades reduce maintenance costs for scattered equipment.
