Maintenance system for vehicle, has wireless data transmission unit for wirelessly receiving data, and central processing unit detecting rank according to transmission signal and transmitting data corresponding to rank

摘要

The system (1) has a wireless data transmission unit (13) for wirelessly receiving data, where the received data is transmitted to a data storage unit (12) by a central processing unit (11). The stored data is taken out from the data storage unit by the central processing unit and transmitted over the wireless data transmission unit. A rank of corresponding weighted value is assigned to the respective data in the data storage unit, so that the central processing unit detects the corresponding rank according to a transmission signal and transmits the data corresponding to the rank. An independent claim is also included for a device for data input and output, comprising an input unit.
