Textile Factory Digitalization Networking Case

I. Solution Overview

1.1 Project Background

With the maturity of industrial digitalization, many factories plan for digitalization directly from the initial construction. A large textile factory has many old production lines that now need digital transformation. The goal is to minimize production stoppages, reduce wiring, and complete digital transformation through local HMI display.

1.2 Objectives

  • Provide network connections for textile equipment at various stages of the factory
  • Use WiFi wireless method to avoid production shutdown
  • Requires stability, unattended operation
  • Can display production data of the entire factory on a large screen

1.3 Applicable Scenarios

  • Digital transformation of old production lines
  • Biochemical culture equipment, intelligent networking
  • WiFi wireless solution for new digital production lines

II. Requirements Analysis

2.1 Current Equipment Status

  • Equipment types: Textile machinery (PLC)
  • Communication interfaces: Ethernet/RS485
  • Communication protocols: TCP
  • Deployment environment: Indoor

2.2 Core Requirements

  1. Access requirement: Ethernet port, RS485
  2. Data requirement: Host computer actively collects data
  3. Network requirement: WiFi, stable automatic reconnection
  4. Security requirement: EMC, isolation from external network

III. Overall Architecture Design

3.1 Architecture

3.2 Data Flow

Device → Industrial router IR302 → WiFi → Local Scada system

IV. Network and Access Solution

4.1 Networking Method Selection

This project uses WiFi wireless network. Needs to support Ethernet port and serial port.

4.2 Router Selection Points

  • Supports WiFi client mode
  • Supports Modbus gateway functionality
  • Industrial-grade wide temperature, dustproof, anti-interference
  • Software and hardware security needs testing

V. Solution Highlights Summary

  1. One-stop: Access + Network + Platform + Application full-stack solution
  2. High compatibility: Multi-device, multi-protocol, multi-network unified access
  3. High reliability: Edge caching, data continuation after network interruption, dual-link backup
  4. Easy expansion: Support batch expansion, secondary development, API integration
  5. Low cost: Reduce manual inspections, improve operation and maintenance efficiency
  6. Security and compliance: Transmission encryption, permission management, operation audit
