Smart Waste Sorting Terminal Solution
Waste sorting in communities, campuses and commercial sites demands accurate recognition of deposited items, control of the deposit port, weighing and incentives, and as little on-site maintenance as possible. Built on RK3576/RK3588 core boards (both with a 6TOPS NPU), this solution integrates waste vision recognition, port and weighing control, an incentive display and remote O&M into one customizable terminal. Hongyin Tech offers a free requirement review and direct engineer access — receive selection advice within 48 hours.
Pain Points
- Sorting relies on residents' discipline, accuracy is low, and manual secondary sorting is costly
- Port, weighing and recognition are linked by hand or simple sensors, causing frequent misjudgment and jams
- Incentive rules and UI requirements change often, making conventional terminal software slow and costly to iterate
- Devices are spread across communities and campuses, so faults surface late and on-site maintenance is expensive
- Outdoor or semi-outdoor deployment demands high stability against temperature, humidity, dust and heavy use
Recommended Hardware Configuration
| SoC platform | RK3576 (4×A72+4×A53) or RK3588 (4×A76+4×A55), tiered by recognition channels and interaction complexity |
|---|---|
| AI computing power | 6TOPS NPU running waste recognition and classification models locally to reduce cloud dependency |
| Memory & storage | LPDDR4/LPDDR5 memory and eMMC storage for local models and deposit record retention |
| Camera input | MIPI CSI/USB camera input supporting top-down recognition at the deposit port (multi-channel expandable) |
| Display & interaction | Touchscreen for deposit guidance, incentive display and user operation, with optional voice prompts |
| Control & interfaces | GPIO/PWM driving the port, weighing sensors and locks, with RS485/Ethernet for platform and module integration |
Software Capabilities
- Waste recognition: NPU runs classification models locally, identifying the category with confidence to guide port opening
- Port and weighing control: recognition links to port opening, weight acquisition and exception handling to reduce jams and mis-drops
- Incentives and interaction: instant credits on deposit, account binding and UI guidance, with rules configurable per operation
- Remote O&M: device status, deposit data and alerts go to the cloud, with remote configuration and firmware updates to cut site visits
- Data integration: interfaces for deposit records and incentive data, easing connection to operations platforms and third-party systems
Deliverables & Services
- Free requirement review: defining waste categories, recognition accuracy targets, interaction flow and deployment environment, with selection advice
- Hardware design: core board selection, carrier board customization, port/weighing/lock interfaces and protective enclosure design
- BSP/driver/algorithm: OS tailoring, peripheral driver adaptation, and waste recognition model training and deployment
- Prototype integration: prototype build, port and weighing linkage testing, and on-site validation of recognition performance
- Pilot and mass production: low-volume orders supported, with continuous supply and firmware maintenance
FAQ
Q：Should a smart waste sorting terminal use RK3576 or RK3588?
Both have a 6TOPS NPU for on-device waste recognition. RK3576 (4×A72 + 4×A53) is more power- and cost-friendly for terminals with simpler recognition and interaction, while RK3588 (4×A76 + 4×A55) offers more compute for multi-camera, complex-UI or multi-function devices. The free requirement review settles the choice, with a reply within 48 hours.
Q：What does smart waste sorting terminal customization cost?
Cost mainly depends on the SoC, camera count and recognition model, the electromechanical structure for port, weighing and locks, and order volume. Training the model for fixed categories can notably reduce inference resources and hardware cost. We do not publish flat pricing — send your requirements and estimated volume for an engineer assessment.
Q：Can the terminal integrate with our operations and incentive platforms?
Yes. The solution provides interfaces for deposit records, incentive data and device status, supporting common protocols such as MQTT and HTTP for integration with operations and incentive systems; private protocols can be adapted during customization. Share your interface docs at the requirement review stage and we will propose an integration plan within 48 hours.
Q：Will recognition and operation stay stable in outdoor or semi-outdoor settings?
The solution uses protective and thermal design for outdoor and semi-outdoor environments, with fanless passive cooling and enclosure protection chosen for local temperature and humidity. Recognition accuracy depends on lighting, camera angle and how items are deposited — we validate with a prototype on-site before large-scale deployment.
