摘要：	The Smart InfraRed Inspection System (SIRIS) is a tool designed to assist inspectors in determining which vehicles passing through SIRIS are in need of further inspection. This is accomplished by measuring thermal data from the wheel components. As a commercial motor vehicle (CMV) travels through the system, infrared cameras mounted on the roadside measure temperatures of the brakes, tires, and wheel bearings on both wheel ends of the vehicle. This thermal data is analyzed by SIRIS internally before being presented to enforcement personnel on a user-friendly interface inside the inspection station. Vehicles that are suspected to have a defect are automatically alerted to the enforcement staff. The main goal of the SIRIS field operational test (FOT) was to collect data to evaluate the performance of the prototype system and to determine the viability of such a system for use in CMV enforcement. From March 2010 to September 2010, ORNL facilitated the SIRIS FOT at the Greene County Inspection Station (IS) in Greeneville, Tennessee. During the course of the FOT, 413 CMVs were given a North American Standard (NAS) Level-1 inspection. Of those 413 CMVs, 384 were subjected to a SIRIS screening. A total of 36 (9.38%) of the vehicles screened by SIRIS were flagged by the system as having one or more thermal issues, with brakes issues making up 33 (91.67%) of those. Of the 36 vehicles flagged as having thermal issues, 31 (86.11%) were found to have a violation and 30 (83.33%) of those vehicles were placed out-of-service (OOS). Overall, the enforcement personnel who have used SIRIS for screening purposes have given positive feedback on the potential of SIRIS. With improvements in detection algorithms and stability, the system will be beneficial to the CMV enforcement community and increase overall trooper productivity by accurately identifying a higher percentage of CMVs to be placed OOS with minimal error.
