LDEV-X — AI-powered test software suite
Design, configure and automate — your way. Six modules, three test models, one suite — Langdi's platform-based test automation software for automotive, robotics, power and energy.
Six modules. One complete testing ecosystem.
Each LDEV-X module works independently — together they cover the full test workflow, from bench definition to data analysis. Lab-wide web management is handled by LD-LMS, the separate lab management product.
Configurator
Configure test systems, signals, test programs, dashboards and protections — the foundation of every LDEV-X testbed.
Automation
Run test programs with live monitoring and logging — reliably, hands-off, around the clock.
Production
Production and end-of-line tests with operator-guided workflows, pass/fail gates and yield tracking.
SCADA
Supervise live plant signals and control loops on mimic dashboards — single-line diagrams, alarms, synchroscope.
DataView
Process, visualise and analyse live and recorded data — turn high-speed measurements into engineering answers.
Simulator
A virtual bench: build and prove test programs against a simulated testbed before they ever touch real hardware.
Open by design
Built-in drivers and open protocols mean LDEV-X also runs equipment you already own — no vendor lock-in.
Engineering test. Production line. Live plant.
One suite covers three very different jobs — and the configuration you build for one carries into the next.
Automation — engineering test
R&D benches and burn-in: test flows, live acquisition dashboards (voltage, current, power, temperature, flow, pressure) and full test logs.
Production — line test
Multi-station dashboards with pass/fail, per-station status, yield percentage and failure drill-down by test step.
SCADA — live plant control
Genset endurance runs, load-bank steps, single-line diagrams, synchroscope and live gauges — supervision-grade control.
Describe, don't code
No test-engineering expertise required — the AI agent guides you through every step of system configuration.
- Natural-language testbed setup — tell the agent what you want to test; it configures the bench automatically.
- Template library — pre-built testbeds for motors, inverters, batteries and more, ready to customise.
- Instant test programs — sequences, signal mappings and validation scripts generated in seconds.
- Offline validation — designs are proven on LDEV-X.Virtual in the office before deployment to the lab.
- Smart optimisation — the platform learns from test data to suggest improvements and catch anomalies.
LDEV-X capabilities at a glance
Custom hardware configuration
Configure test equipment freely using built-in drivers and communication protocols.
User-defined test programs
Create custom test sequences and scripts for complex, diverse workflows.
Offline design + validation
Design test programs in the office and prove them on the Langdi Virtual Test Bench before they reach hardware.
Multi-protocol support
High-speed data logging
Up to 10 parallel data loggers — 1000 channels @ 1 kHz.
100-device integration
Simultaneously operate up to 100 measurement devices on one bench.
Real-time testing
Seamless integration with the LDRT real-time bench controller for HiL testing.
Lab-management ready
Pairs with LD-LMS to put every LDEV-X bench on one web dashboard.
