infrared intelligent sensors basic IRMA Reliable counting, robust engineering, low system price IRMA basic passenger counting system is a low cost entry into passenger counting operations. IRMA basic delivers a continuous and reliable stream of high-quality counting data for applications such as statistical measurement and distribution of revenues or the determination and control of transit system performance (passenger kilometres, pkm). Discreet and unobtrusive, sensors monitor the door space while permanently sending out IR light pulses, which are reflected by any passengers present and detected again by the sensors. The user can choose between two system architectures: IRMA Basic and Basic CAN. The alternatively available M12 cabling minimizes wiring in vehicles. The sensors are linked to the CAN system bus. • Highly sensitive active IR detector • Recognition of the direction of movement (boarding and alighting passengers) • Support of standard systems interfaces (IBIS, RS232, RS485, J1708) for connection to existing telematics systems (on-board computer, ticket printer) • Combined use with GLORIA II radio data transmission module possible • Easy unobtrusive installation within the vehicle • Optionally, M12-CAN cabling can be provided for simple cabling scheme in multiple-door vehicles (recommended for vehicles with more than two doors) • Connection of up to 4 reaspectively 8 sensors to one analyzer (for a maximum of 4

analyzer data interface power supply service interface door contact On vehicles with more than 2 doors: The analyzer with CAN cabling is designed to connect with up to eight sensors (type IRMA Basic CAN). This allows for four wide doors per analyzer. analyzer data interface power supply service interface door contact On vehicles with 2 or less doors: The analyzer is designed to connect with up to four sensors (type IRMA Basic). This allows for two wide doors per analyzer. system ComponentS • Counting of passengers in vehicles with standard requirements regarding counting accuracy •...
