Event-controlled telematics unit for monitoring a load carrier and method for operating the telematics unit

摘要

The invention relates to a telematics unit (10) for monitoring a load carrier (20), at least comprising a memory (13), an activation unit (30), a monitoring unit (40) and an energy source (12) which is used to supply energy to the components of the telematics unit ( 10) is used. The activation unit (30) has at least one real-time clock (32), a sensor module (33) and an activation unit (30), and the monitoring unit (40) has at least one locating means (42), a communication means (43) and a second processing unit (41). Data transmission means (11), with which the activation unit (30) and the monitoring unit (40) can be connected to one another, are connected between the activation unit (30) and the monitoring unit (40), the first computing unit (31) being designed as the activation unit (30) to evaluate a signal from the real-time clock (32) or the sensor module (33) and, based on this signal, to transmit an activation signal to the monitoring unit (40), by means of which the monitoring unit (40) switches from a standby state with lower power consumption to a Working state with higher power consumption is switchable. The second computing unit (41) of the monitoring unit (40) is also designed to send at least position data generated by the locating means (42) via the communication means (43) to a central data processing system (50) and / or to query information therefrom, with im Memory (13) of the monitoring unit (40) tour information for the load carrier (20) is stored, and the computing units (30, 40) of the telematics unit (10) means for linking this tour information with the real-time clock (32), the sensor module (33 ) and / or the location means (42) have information provided and for evaluating this link. The invention also relates to a method for operating such a telematics unit.
