The LHP Hardware-in-the-Loop Test Platform (LHP/HTP) leverages tools, experience, and partnerships with National Instruments and MathWorks combined with the LHP Engineering Solutions body of knowledge to deliver powerful test assets at reasonable costs. The HTP uses NI hardware and software (LabVIEW/VeriStand/TestStand) to deliver extraordinary I/O capability, processing power, test management, user interfaces, and reporting. The HTP runs a Simulink real-time plant model which provides capabilities to faithfully simulate normal plant operation or complex fault conditions. The system architecture, DUT interfaces, and signal conditioning are custom configured for each application while leveraging re-use of LHP developed solutions
Interested in finding cost-effective test solutions?
LHP has designed a 3 Tier Test Environment Architecture approach to providing test solutions to our clients:
TIER 1 - HTP Manual Testing Architectural Model
TIER 2 - HTP Automated Test Architectural Model
TIER 3 - HTP Reconfigurable Automated Test Architectural Model
Client-selected options extend each architecture tier to further tailor the system to meet the requirements based upon blocks that each build up to the next tier. Thus, the HTP can be made extensible and grow according to client needs. LHP Engineering Solutions can provide a basic open loop system, a closed loop automated system, a complete data-driven total test automation system with traceability to requirements, as well as variations to those architectural tiers.
