What Parts Make Up A Digital Tachograph System?
The digital tachograph consists of a vehicle unit, motion sensor and smart card. Vehicle Unit : The vehicle unit is the main part of the system. It consists of a printer, display, user interface buttons and 2 smart card slots. It holds the driver data (driving that vehicle), driving and duty periods over the last 365 days, faults data, calibration details and over speed and excessive drive times. Motion Sensor : The motion sensor provides a signal representation of vehicle speed and/or distance travelled to the vehicle unit in an encrypted form. Smart Card : This smart card is a white plastic card similar to a credit card in size and shape. It has a microchip on it and records activity and other details, similar to those now recorded on a conventional tachograph chart.
