On-board Emissions Measurement System
OBS-ONE is the latest Portable Emissions Measurement System designed for engine/vehicle certification under real road conditions.
It measures concentrations of emissions (CO, CO2, THC, NOx, NO2), particulate matter, air-to-fuel ratio, exhaust flow rate, GPS data, environmental conditions (atmospheric temperature, humidity and pressure) and calculates mass emissions.
OBS-ONE features the highly adaptable, intelligent operating platform called “HORIBA ONE PLATFORM” which integrates other ONE series product data and optimizes test cell operation.
HORIBA has developed broad emission test applications for certification and engine/vehicle R&D, such as simulating a real-world driving event in the test cell with the Test Automation System-STARS. This simulation requires data combined from the OBS-ONE and a drive recorder.
◎ Easy to Install
◎ Stable Operation Over Long Driving Periods
◎ Safe
◎ Accurate
◎ Measurement
Comprehensive test package includes self-diagnosis, quality check, and sensitivity calibration before testing.
Guides the entire process (preparation, measurement data post processing, etc.) from before to after testing.
[ Real-time Validation and Guidance ]
・Checks measuring data during testing to avoid invalid results
・Driver can concentrate on driving without any operation once measurement is started
◎ Data Post Processing
Complicated process of calculation and analysis made simple
・Suitable calculation and result output for LDV/HDV
・Makes test report for certification
・Shows the camera-recorded drive replay and the GPS map related to measured data
・Complies with ASAM-ODS* standard
※ASAM-ODS: Association for Standardization of Automation and Measuring Systems ｰ Open Data Service
Integrated Operation Software “HORIBA ONE PLATFORM”The newly developed software for the OBS-ONE is integrated with the same operating platform as the MEXA-ONE, CVS-ONE and other devices. The intuitive, ergonomic design of the new software platform makes system operation easier. System control and a complete system view of other measurement devices are available from one single display. User support for system operation such as maintenance, alarms, and message functions has been further enhanced.
・Future expandability of PN counting and additional pollutant measurement, etc.
・User-friendly screen configuration and layout offer both measurement efficiency and convenience
Achieving real-world simulation in the test lab
OBS-ONE provides real driving emission test as well as real driving simulation in the test lab by utilizing STARS.
This comprehensive solution ensures accurate emissions data from both real-road and laboratory testing conditions.
