Architecture
Core Components
The DistriVend architecture is composed of three primary layers: the Edge Layer, the Cloud Layer, and the Integration Layer. The Edge Layer consists of the vending units themselves, each equipped with a controller, a display module, a payment terminal, and an IoT gateway. These units communicate with the Cloud Layer via secure MQTT or HTTPS protocols. The Cloud Layer hosts the central management console, analytics engine, and transaction database. It also provides scalability and redundancy through container orchestration platforms such as Kubernetes. The Integration Layer facilitates communication between DistriVend and external systems, including enterprise resource planning (ERP) software, customer relationship management (CRM) tools, and third‑party payment processors.
Communication Protocols
To ensure reliability across diverse network environments, DistriVend employs a dual‑mode communication strategy. Primary data exchange occurs over HTTPS for secure, high‑bandwidth scenarios, while fallback communication utilizes MQTT over cellular connections. The MQTT implementation incorporates Quality of Service (QoS) levels 1 and 2 to guarantee message delivery. Edge devices cache critical commands locally and retry transmissions in the event of connectivity loss, thereby maintaining operational continuity even in low‑bandwidth regions. The platform’s API layer exposes RESTful endpoints for integration with external services, enabling real‑time inventory synchronization and order fulfillment.
Key Concepts
Distributed Control
Unlike conventional vending systems that rely on a single control unit, DistriVend distributes control responsibilities across edge devices and the cloud. Each vending unit independently handles sensor data, customer interaction, and local transaction processing, while the cloud manages global inventory, pricing strategies, and regulatory compliance. This distributed approach enhances fault tolerance; a malfunctioning unit does not bring down the entire network. Additionally, it allows for localized decision making, enabling vending units to adapt to regional preferences or time‑based promotional events.
Transaction Management
Transaction handling within DistriVend is designed to support a wide array of payment methods, including credit/debit cards, NFC contactless payments, mobile wallets, and prepaid voucher systems. Each transaction is processed in a two‑phase commit protocol: the edge device authorizes the payment locally and reports the result to the cloud, which updates the central ledger and triggers inventory adjustments. The system generates digital receipts and can optionally send them via email or SMS. Audit trails are maintained in a tamper‑evident log, with optional blockchain hashing for compliance with stringent security standards.
Inventory Tracking
Inventory monitoring is performed through a combination of weight sensors, barcode scanners, and RFID tags. The edge device collects raw sensor data and applies filtering algorithms to detect discrepancies between expected and actual stock levels. The aggregated data is transmitted to the cloud, where machine‑learning models forecast demand and suggest restocking schedules. The platform provides administrators with dashboards that visualize stock velocity, reorder points, and shrinkage rates, enabling data‑driven decision making.
Customer Interaction
DistriVend supports multiple customer interaction modalities. The user interface on the vending unit can display touchscreens, QR codes, or voice‑enabled prompts. The system is capable of adapting the interface based on demographic data inferred from cameras or mobile device detection. Moreover, the platform can integrate loyalty programs and personalized offers, leveraging customer profiles stored in the integration layer. These features aim to enhance the user experience and increase repeat patronage.
Implementation
Hardware Integration
Hardware integration follows a modular design. The core controller is compatible with standard microcontroller platforms such as ARM Cortex‑M and x86‑based single‑board computers. The payment terminal integrates with PCI‑compliant chip‑and‑pin readers and NFC modules. Display modules include LCD and OLED panels, with support for high‑resolution touch input. The vending chassis is designed for easy maintenance, allowing for quick replacement of dispensing mechanisms and sensor modules.
Software Stack
The software stack on edge devices comprises an embedded Linux distribution, a lightweight application runtime, and a container runtime for isolating microservices. The core application handles device management, sensor data acquisition, and local transaction processing. Edge services communicate with the cloud through a secure MQTT broker. The cloud stack utilizes a microservices architecture, with components written in languages such as Go, Java, and Python. Data persistence is achieved through a combination of relational databases for transactional data and time‑series databases for sensor telemetry.
