1. Core Components of the Interconnected System
| Module | Function Description |
|---|---|
| Intelligent Soiled Linen Chute | - Each delivery door on each floor is equipped with an RFID reader/QR code scanner to automatically record the delivery department, time, and linen type |
| Automatic Sorting Terminal | - The bottom is connected to a weight sensor + AI visual recognition, classifying by color/material (e.g., medical textiles vs. guest room linens) |
| Conveying System | - The end of the chute is connected to a belt conveyor/AGV vehicle, directly to the laundry pre-treatment area |
| Central Control Platform | - Real-time monitoring of the status of each link (e.g., bin accumulation alarm, laundry machine group load balancing scheduling) |
2. Key Points for Efficiency Improvement
Shorten Turnaround Time
Traditional mode: Manual collection → Cart transportation → Manual sorting (takes 40-60 minutes)
Interconnected mode: Direct chute conveying → Automatic sorting → Washing queue (total ≤15 minutes)
Reduce Labor Costs
Reduce linen handling positions by more than 60% (especially suitable for multi-story buildings)
Precise Traceability Management
RFID tags track the entire process, avoiding confusion of linens between departments (e.g., hospital infection control requirements)
3. Intelligent Function Expansion
Dynamic Priority Adjustment
When emergency department/operating room soiled linen is delivered, the system automatically increases the washing priority of that batch
Consumption Warning
AI analyzes the damage rate of linen (e.g., towel fiber breakage), suggesting replacement cycle
Energy-Saving Interconnection
Pre-heat laundry equipment based on the accumulation of soiled linen in the chute
4. Implementation Case Reference
A Five-Star Hotel Solution
Soiled Linen Chute Configuration : Φ500mm stainless steel pipe, 22-story vertical shaft, electronic access control on each floor (employee card access control)
Sorting Logic :
White linen (sheets, pillowcases) → Main washing line
Colored linen (restaurant tablecloths) → Independent washing channel
Effectiveness : Linen turnover rate increased by 35%, nighttime noise complaints decreased by 90% (soundproof chute + restricted delivery time)
5. Precautions
Compatibility Verification : Existing laundry equipment interfaces need to support communication protocols such as OPC UA/Modbus
Disaster Recovery Design : Retain manual sorting backup channel (to prevent system failure paralysis)
Hygiene Compliance : Hospital systems must comply with WS/T 508-2016 "Technical Specifications for Washing and Disinfection of Medical Textiles in Hospitals"
