Scenario development scope
Field devices and terminals
Focus on the development of 4G engineering machinery remote information terminals, 4G development of unmanned vehicles and robot operation and maintenance gateways and other products to clarify the interface, power supply and installation conditions, and develop or transform terminals.
Business and data
According to the device bus and status → Operation and maintenance terminal → 4G → Task and device profile → Diagnosis and maintenance, define data, events, commands and results, and retain the association between devices, 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 bus authorization, operation and job status, task validity period, mobile network and local control responsibilities, and clarify the responsibilities and exception handling of local and remote systems.

View Development Scope and Deliverables →System composition and business process
Device bus and status → Operation and maintenance terminal → 4G → Task and device files → Diagnosis and maintenance.
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 points to confirm: bus authorization, operation and operation status, task validity period, mobile network and local control 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 bus authorization, operation and job status, task validity period, mobile network and local control 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.

How to divide the work between remote operation and maintenance and the local control system?+
The operation and maintenance side is responsible for telemetry, task status, logs and authorized configuration, and the local control is responsible for movement, protection and emergency stop. The interface needs to clearly define acceptance conditions, disconnection behavior and execution result feedback.
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 bus authorization, operation and job status, task validity period, mobile network and local control responsibilities, and then determining the reusable scope and return work.
