Title: Check system
Inventor: TASHIRO TAKASHI
IPC: G01R31/26
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To quickly automatically check the operation of a comparator for ID of burn-in board with high accuracy by outputting a check pattern to the comparator after the ID of a diagnostic board is sent to a test burn-in device from an ID setting section. SOLUTION: The characteristic ID code of a diagnostic board 20 set to a jumper line 1 for setting ID is read to a CPU 105 by switching a change-over switch 2 to its b-contact when PS power source 101 is turned off while the board 20 is connected to a test burn-in device 100. The CPU 105 turns on the power source 101 after confirming that the board 20 is an aimed board 20 from the read ID code and makes a check pattern stored in a memory 3 to be outputted to a comparator 103 through a switch 4. Since various kinds of check patterns used for the comparator 103 are stored in the memory 3 and the data can be set arbitrary with a program, various kinds of patterns can be checked easily when the CPU 105 reads and confirms ID codes.

Inside the area of road-to-vehicle communication, a road-to-vehicle communication control part 306 transmits the data packet during the frame control slot period synchronously with a communication frame from the information of detecting the communication frame. The road-to-vehicle communication system does not use the frequency channel for up communication during the frame control slot period. Inside the area of road-to-vehicle communication, vehicle-to- vehicle communication is enabled without disturbing the road-to-vehicle communication.
