Development Scope
Device and interface access
Adapt to cargo lanes, shipping detection, door status and inventory interfaces, and establish mapping between payment results, order numbers and equipment execution.
Product business functions
Connect goods lanes, payment results and equipment sensors to develop order status, shipment verification, exception compensation, inventory and remote diagnosis.
Platform and data connection
Combined with the business link of order or authorization → local condition check → device execution → 4G result return → order and maintenance management, the device identity, data fields, update time, exception status and result confirmation method are defined.
Exception handling and operational constraints
Payment results and shipping results need to be checked separately; refunds or compensation are handled according to the customer's authorization platform process, and repeated orders must not trigger repeated shipments.
Data and Operational Workflow
Platform order confirmation → Dispatch a vend command over 4G → Vending channel actuation and detection → Result acknowledgment → Inventory and abnormal order processing.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business processes and parameters: cargo lane and shipping detection, order identification, inventory rules and exception compensation.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Test normal shipments, stuck goods and detect abnormalities. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Verify order duplication, timeout and reconnection recovery. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Check the consistency of inventory changes and order results. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
Will disconnection and reconnection result in repeated shipments?+
Terminals and platforms should save execution status according to unique order identifiers and define retry and query processes. When restoring the network, check the results first and then decide whether to continue the operation. The specific behavior is verified through fault use cases.
Is it possible to delegate only part of the functionality of the vending machine control panel?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing information and target boundaries, first check "cargo lane and shipping detection, order identification, inventory rules and exception compensation", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking cargo lanes and shipping inspections, order identification, inventory rules and abnormal compensation; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
