Development Scope
Device and interface access
Integrate QR code scanning or RFID, camera, 4G and selected operating system to clarify task fields, identity permissions and attachment collection methods.
Product business functions
Integrate code scanning or RFID, photography and cellular networking, development task distribution, offline forms, data synchronization and device management.
Platform and data connection
Combined with the business link of on-site tasks or measurements → device identification and recording → local storage → 4G synchronization → enterprise archiving and operation feedback, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
The terminal application and background task versions must be consistent; conflict handling must be defined for offline editing, attachment retransmission, and multi-person operations.
Data and Operational Workflow
Task distribution → on-site identification equipment → form and photo collection → local storage → 4G synchronization → background review.
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: task fields, code scanning or RFID, offline forms and synchronization conflict rules.
- 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 | Check the scan result with the device file. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Test offline forms, photo caching and resume sync. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify task versions, permissions, and duplicate submissions. |
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
Can I continue to fill in the form when there is no signal at the inspection site?+
Received tasks and necessary dictionaries can be saved locally, and forms and attachments can be recorded. After the network is restored, synchronize by task version and record identification, and give clear status to conflicting or expired tasks.
Can I entrust only part of the functions of the handheld inspection terminal?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing data and target boundaries, first check "task fields, code scanning or RFID, offline forms and synchronization conflict rules", 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 task fields, code scanning or RFID, offline forms and synchronization conflict rules; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
