Scenario development scope
Field devices and terminals
Focus on 4G vending machine control board development, 4G shared rental cabinet control system development and other products to clarify the interface, power supply and installation conditions, and develop or transform terminals.
Business and data
Define data, events, commands and results based on order or authorization → Local condition check → Equipment execution → 4G result return → Order and maintenance management to retain the association between equipment, sites or projects.
Platform and operation and maintenance
Connect with existing enterprise platforms, or develop device management, historical data, alarms, permissions and client functions, and determine the scope by module.
system constraints
In the planning stage, check order identification, execution detection, repeated commands, exception compensation and payment interface responsibilities, and clarify the responsibilities and exception handling of local and remote systems.
product development services
Select corresponding technical services based on field equipment and target business. You can start with a single terminal or combine multiple device types. The following products describe the interfaces, business processes, delivery materials and acceptance methods respectively.

View Development Scope and Deliverables →System composition and business process
Order or authorization → Local condition check → Equipment execution → 4G result return → Order and maintenance management.
The platform manages devices according to enterprise projects, sites and permissions. After the link is restored, check the data and service status; when control is involved, separately confirm command authority, timeliness, local conditions and execution feedback.
Project Inputs
- Target business, equipment list, on-site location, equipment size and users.
- Wiring, protocols, raw data and open software interfaces to existing equipment.
- Key confirmations: order identification, execution detection, repeated commands, exception compensation and payment interface responsibilities.
- Platform status, data retention, client and deployment methods, prototype and on-site verification conditions.
Deliverables and Acceptance
| stage | Delivery content | Verification basis |
|---|---|---|
| Needs and plans | Equipment interface list, business process, system architecture and development division of labor | Check order identification, perform detection, repeat orders, exception compensation and payment interface responsibilities. |
| Development and integration testing | Agree on terminal hardware, firmware, interfaces and platform applications | Check the fields, status, instructions and abnormal behaviors one by one according to the actual device. |
| Acceptance and handover | Prototype or program, design and deployment data, test records and version list | Accept according to the agreed environment, sample, duration and threshold, and record the handling of failed items. |
R&D, prototype materials, structure, testing, on-site implementation and subsequent operation and maintenance are listed separately. Project cost and cycle are evaluated based on equipment type, interface complexity, existing foundation and verification workload.

View Development Scope and Deliverables →Frequently Asked Questions
Can I build a control panel first and then connect it to different operating platforms?+
Device execution and platform access can be separated and connected through clear message and status interfaces. When changing platforms, you still need to verify the consistency of orders, authorizations, receipts, and exception handling.
Can I reuse existing platforms and terminals?+
You can first check the existing interfaces, data and code, and focus new development on the missing links. This scenario requires focusing on checking order identification, execution detection, repeated commands, exception compensation and payment interface responsibilities, and then determining the reusable scope and regression work.
