Entrance Road Weighing & Access Interlock
Chunxiao Technology · 2015 – 2017
Role: Developer (Field Software Integration)
Entrance Road Weighing & Access Interlock
Customer-site vehicle weigh-in system: read stable weight from entrance scales, raise overload warnings, and interlock with barrier/signal hardware. Serial/device integration with Delphi under field constraints.
Delivered field weighing integration with barrier interlocks under tight schedules
Problem
Vehicle entrance weighing needs reliable software integration with scales, barriers, and alarm hardware in industrial environments.
Solution
Field integration: serial communication for weight reading, overload threshold detection, barrier/signal hardware interlocks. Shipped in Delphi for speed, with documented interfaces for maintainability.
Key Highlights
- ▸Field workflow: vehicle on scale → software reads weight → triggers alarms → coordinates barrier interlocks
- ▸Advocated for team-aligned stack over individual familiarity
- ▸Documented interfaces and operational risks for next maintainer
- ▸Professional execution under non-preferred stack decision

What I Learned
Technical disagreements should focus on maintainability and bus factor; when the org picks a lane you don't own, execution quality and written-down risk beat hallway debate.
