Development Scope
Scope and Basic Check
Determine the existing foundation, technical dependencies and content that needs to be developed based on the original equipment interface, power supply, structure, control responsibilities, changeable code range and target platform.
Implementation and integration
Compare the three paths of connecting an external gateway, adding a communication board, and revising the motherboard. Prioritize the responsibility boundaries between the original equipment and the new terminals, and then implement integration testing of the interfaces.
Delivery Documentation
Implementation materials, interface descriptions and test records.
Verification and Constraints
Accessibility is not judged by the appearance of the interface; when changes to the original controller or firmware are involved, the authorization and return scope should be clearly defined.
Project implementation process
Verification of data and interfaces → Confirmation of technical solutions and verification use cases → Implementation of integration with the target environment → Regression of abnormal scenarios → Transfer of version data.
Verify the implementation results in the target hardware and software environment, and deliver records of associated interface configurations, version dependencies, and problem handling to facilitate subsequent integration and maintenance by the enterprise R&D team.
Project Inputs
- Original device interface, power supply, structure, control responsibilities, changeable code range and target platform.
- Design information, code, interface permissions and target test equipment can be provided.
- Source files, programs or tools expected to be delivered, inter-module integration testing responsibilities and project nodes.
- Acceptance samples, environment, test conditions and passing thresholds.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| achieve results | Implementation materials, interface descriptions and test records. | Check the original functions before and after renovation. |
| Integrated data | Versions and dependencies, interface configuration, usage or deployment steps, and integration changes | Test the impact of new communications on power and bus. |
| Verify records | Test conditions, execution records, problem lists and regression results | Verify network outages, power outages, and maintenance operations. |
The delivery scope and acceptance criteria are determined based on the target environment. Third-party SDK, licenses, laboratories, cloud resources, equipment materials and on-site support are listed separately; when the existing information is insufficient, follow-up work will be determined through interface verification or key function verification.
Frequently Asked Questions
How to proceed if the original equipment does not have an open protocol?+
First confirm the available authorization information and readable signals, and add independent sensors if necessary. The feasibility assessment should first determine the range of data that can be verified before agreeing on subsequent development.
What information do I need to provide first for connectivity retrofit of existing equipment 4G?+
Please give priority to providing the original device interface, power supply, structure, control responsibilities, changeable code range and target platform. At the same time, the existing implementation, problems encountered, expected changes, and compatible test conditions are explained to facilitate the determination of implementation scope and reproduction methods.
Can it be implemented on existing products?+
You can first evaluate the scope of existing designs and versions that can be changed, retain the verified parts, and determine the interfaces and dependencies that need to be adjusted. This service requires attention: Accessibility is not judged by the appearance of the interface; when changes to the original controller or firmware are involved, the authorization and return scope should be clearly defined. Existing and new functions must undergo regression testing within the agreed scope after the changes.
