Background

With the application of the smart Trash Can system, the situation of full bin, disorderly trash stacking and stinking The Smart Trash Can system revolutionizes urban waste management by addressing common issues such as overflowing bins, disorderly trash accumulation, and unpleasant odors. Leveraging a blend of sensor technologies, mechanical actuation, and 4G/3G IoT connectivity, this solution offers a fast, accurate, and convenient method for managing waste. By monitoring trash levels and environmental conditions in real time, cities can optimize waste collection schedules, reduce operational costs, and lower CO₂ emissions.

WLINK Solution

WLINK’s Smart Trash Can solution integrates a range of sensors—including gravity, ultrasonic, smoke, temperature/humidity, and odor sensors—to continuously gather data on bin status. This data is transmitted via a 4G/3G network to a centralized cloud platform, enabling remote monitoring and management. When a bin is nearing capacity or conditions indicate potential issues, the system generates an alert, prompting timely dispatch of personnel and vehicles for trash removal.

Solution Composition

1. Trash Can and Mechanical Transmission Device

• Trash Feeder:
  Features an infrared induction system for automatic cover opening and a speed reducer to ensure controlled operation.

• Hydraulic Power System:
  Provides a lifting capacity of no less than 260kg, with integrated safety confirmation functions.

• Lifting Mechanism:
  Equipped with a built-in 660L trash can, a drop safety device, and a leveling mechanism.

• Drainage System:
  Automatically removes water from the foundation pit to prevent damage and maintain cleanliness.

• Deodorization System:
  Utilizes anion technology to neutralize odors, improving the bin’s environment and the surrounding area.

2. Sensors Suite

• Weight Sensor:
  Monitors the real-time weight of the trash to gauge fill levels.

• Ultrasonic Distance Sensor:
  Detects the overflow state of the bin, ensuring timely alerts.

• Smoke Sensor:
  Identifies the presence of smoke, triggering alarms if fire hazards are detected.

• Temperature and Humidity Sensor:
  Tracks environmental conditions within the bin to ensure optimal operation.

• Odor Sensor:
  Measures levels of unpleasant smells and activates the deodorization system when necessary.

3. Data Acquisition and Communication

• RT600 RTU:
  Supports multiple interfaces including 2 RS232 ports, 2 RS485 ports, a CANBUS interface, 2 analog inputs (AI), 2 digital inputs (DI), and 1 digital output (DO via relay).

• 4G Router:
  Provides robust 4G communication, with optional GPS and CANBUS interfaces  for enhanced data integration and tracking.

4. Cloud platform

The cloud-based management platform displays real-time sensor data and site distribution on a panoramic map, enabling operators to:

• Monitor Operational Status:
  View live data such as temperature, humidity, fire alarms, and bin capacity.

• Remote Equipment Management:
  Control and maintain remote trash cans through real-time data analytics to extend equipment lifespan and enhance system stability.

• Data Analytics:
  Store sensor data in a database and generate detailed reports to support decision-making and predictive maintenance.

Benefits

• Automatic Induction:
  The smart bin opens and closes via sensor induction, minimizing direct contact and reducing the risk of viral transmission. The feeder port automatically closes to mitigate the spread of odors.

• Real-Time Remote Monitoring:
  Easily access live data on environmental conditions and bin status anytime, ensuring timely maintenance actions.

• Timely Alerts:
  When a bin is close to overflowing, the system sends immediate alerts, triggering trash removal and preventing secondary pollution.

• Enhanced Urban Cleanliness:
  Customizable bin designs enhance urban aesthetics, while precise trash sorting and prompt cleaning contribute to a cleaner, more attractive city environment.
