📋 Case Study
EU Precision Vineyard Sprayer Compliance Audit
Failed audit due to missing NOx and particulate matter reporting fields in telematics export
🏗️ Project Overview
14 self-propelled sprayers (Amazone, Grimme, Horsch) operating under EU Stage V regulatory enforcement
🎯 Challenge
Failed audit due to missing NOx and particulate matter reporting fields in telematics export
🔧 Design Approach
Reverse-engineered OEM firmware logs to identify hidden SPNs; implemented custom ISO 11783-10 JSON wrapper with mandatory EU emission fields

📐 Key Calculations
NOx Emission Estimation
SPN 411 × SPN 412 × 0.00012 (g/kWh)
Result: 1.82 g/kWh
Within EU Stage V limit of 2.0 g/kWh
PM Reporting Completeness
Reported PM SPNs / Required PM SPNs
Result: 100%
Passed post-audit verification
📊 Results
Passed regulatory re-audit; enabled subsidy eligibility; reduced administrative reporting time by 70%💡 Lessons Learned
- •OEMs embed emissions SPNs in non-standard PGNs
- •EU compliance requires both real-time and aggregated reporting windows
- •JSON schema must include ISO 11783-10 metadata headers for traceability
