PURPOSE:To enable processing corresponding to the management of vehicle operations by writing detected operation data and inputted item data in a stor age medium together with time data at the time of the input when items are interactively inputted. CONSTITUTION:A CPU 200 is integrated as a one-chip microcomputer together with an A/D converter and a main memory, for example. Then, the respective parts of an operation recorder 2 are controlled, the operation data inputted from an operation sensor part 202 are sampled, A/D converted, afterwards, averaged by data compression and stored in the main memory, and data write into an IC card 3 is controlled. The A/D converter quantizes the operation data inputted from the operation sensor part 202. Further, a maximum amplitude value from the peak hold circuit of an interface is converted to the quantized data of 8 bits, and the eight sets of sample data are simultaneously fetched. The main memory temporarily stores the operation data quantized by the A/D converter. |
