Field Data Transfer Bridge
A pilot integration for forwarding field data through a local queue to a central system, developed as part of the production tracking work.
What this role enables
- 01
Provision a pilot connection for a production point.
- 02
Switch between existing and pilot collection methods with confirmation.
- 03
View last-contact information and connections awaiting a test.
- 04
Pause a connection for maintenance and resume it afterwards.
Institutional context
A pilot combining firmware and central application integration. It does not claim uninterrupted field operation or proven production success.
My contribution
- Developed firmware separating data collection from transmission.
- Implemented persistent queueing and retry behaviour.
- Integrated pilot provisioning and collection-mode selection into the central panel.
Problem
Communication between the field data source and the central application needed a separate layer that considered connection interruptions and a gradual migration path.
Constraints
- Integrate with the existing production application in stages.
- Use limited local storage, without guaranteeing retention of every record during extended outages.
- Keep the scope explicitly at pilot stage pending field reliability and long-running validation.
- 01Read field data
- 02Queue locally
- 03Send to the centre
- 04Evaluate the response
- 05Expose status
Approach
I separated reading, local queueing and forwarding. Pilot activation was designed as a controlled transition that could be managed alongside the existing collection method.
Solution built
I developed firmware with a persistent local queue, retries after failed submissions and authenticated data transfer. The central application gained management views for pilot provisioning, collection-mode selection and last-contact information.
For management
- Provision a pilot connection for a production point.
- Switch between existing and pilot collection methods with confirmation.
- View last-contact information and connections awaiting a test.
- Pause a connection for maintenance and resume it afterwards.
Institutional impact
The work establishes a technical foundation for an alternative data-transfer path within the existing production system. It is not presented as a field-accepted solution or a guarantee against all data loss.
Technical scope
- Microcontroller firmware development
- Persistent local queue and retries
- Authenticated API communication
- Central application integration
- Pilot transition and status monitoring
